    How Satellites Track Your Exact Location

    January 12, 2020


    GPS satellites are constantly bathing the
    world in their electromagnetic signally glow, but how EXACTLY do these satellites find you? Saying a satellite finds YOU is very Enemy
    of the State, very NBC TV government drama; but GPS satellites don’t actually track you,
    they’re simply broadcasting a signal that you pick up. What would be a more accurate
    way to look at it is, GPS doesn’t find you, but you find it. The Global Positioning System is network of
    around 30 satellites, a receiver, and a SUPER accurate clock; all pulled together with math.
    The system was created in the 1980s for the military, but they opened it up for civilian
    use, and it has since changed how we find directions, look for pizza, and connect with
    each other. But how it works, requires a TON of incredible science. Firstly, we have to know what time it is.
    I know that seems strange, but if you don’t have a SUPER ACCURATE measure of time, you
    can’t do GPS! The most accurate measure of time humans have, is the constant, predictable
    vibration of an atom. The U.S. Naval Observatory in Washington, D.C., is the official United
    States time. They mark time, by measuring billionths of a second using 9,192,631,770
    electron vibrations of a Cesium-133 atom. This atomic clock is accurate to nanoseconds…
    which is super important. Secondly we have to have a satellite network
    which ALSO know the time. As of October 19, 2015, there were GPS 31 satellites with three
    atomic clocks on board, as well as transmitters to send microwave signals out at the planet
    below. The system is flying at 11,000 kilometers per hour, about 20000 kilometers above our
    heads (7000mph/12500mi) and is maintained by the U.S. Air Force. Those signals? Those
    are what are telling you where you are on the planet! Okay, so. GPS signals are sent at exact intervals.
    Say… every few seconds. Embedded in microwave signal is the ID of the satellite, the health
    of the satellite, the location of all the satellites in the system, and the precise
    date and time. VERY precise. Because Tens of thousands of kilometers away on the ground,
    the signals will be picked up by your smartphone once you click, let the pizza app know your
    location. Smartphones and GPS units have to have very
    precise time, because microwave signals travel at the speed of light, roughly 300,000 kilometers
    per second, so in a fraction of a second, the signal travels from each satellite to
    you! This is why we need atomic clocks, because 20-30 nanoseconds matter! But we’ll come back
    to this in a sec. The receiver can tell where each satellite is, by the difference in time
    lag. Using a mathematical process called trilateration the GPS unit can determine your exact location.
    Basically, a sphere is drawn indicating the time lag from each satellite and the overlapping
    point is your current location! After ALL THAT, the pizza app knows exactly where you
    are. Before you get confused, there’s NOT an atomic
    clock in your smartphone, but as long as the smartphone clock is pretty good, it can will
    regular updates from the Observatory clock and stay on track! The more satellites it
    can “see” the more accurate the location. If you pick up three satellites, your GPS
    can determine your 2D location (latitude and longitude), but with four it can tell your
    altitude too! As you move, the time lag from the satellite to the antenna of each signal
    will change, and by constantly updating the trilateration math, the location dot on your
    map moves. Even after all this work just to get a pizza
    delivered, there’s a ton more complications. Satellites need replacement, and only have
    an operational life of 7-15 years. So they have to keep launching new ones. We’re on
    our fifth generation now, and they’re getting a lot better, but they’re not perfect. The
    satellite signals can bounce off an ionized layer of the atmosphere called ionosphere
    — AM radio bounces off it from the ground too. It’s not friendly to signals going through
    it. But on top of THAT GPS satellites are traveling FAST and far away, meaning Einstein’s
    General & Special Relativity comes into play. Even if the atomic clocks are super accurate,
    the ones on the satellites are ticking faster than the Naval Observatory clock, because
    gravity is stronger on Earth and they’re moving so fast! SO! The GPS has to mathematically
    calculate and adjust for the roughly 45,000 nanoseconds per day of difference in time;
    since being off by 20-30 nanoseconds can make the system pretty much worthless. This a big
    deal. It’s frickin’ crazy. Thanks to the space program, Einstein’s relativistic
    physics, atomic clocks, and smart phones, you my friend, can get a pizza delivered to
    your exact location — give or take a few feet. What do you want? We’re not perfect.
    Yet. The next generation should get us within inches. And thank you also to the US Air Force for
    sponsoring this message, and making sure the pizza guy knows where to come. Every day American
    Airmen go above and beyond to break barriers both professionally and personally. The United
    States Air Force is powered by Airmen, fueled by innovation.
    Crazily enough, your BRAIN has GPS too, after a fashion. A set of cells creates a map of
    the stuff around you… No, no, I’ll let this super handsome guy with a great t-shirt collection
    explain it.

    What if Earth was INVERTED? (Geography Now!)

    December 22, 2019


    Hey Geographypeeps how are you doing? So as you know, this is ‘Filler Week’ which means every time we finish four episodes we take some time off to research for the next ones But I don’t leave you hanging I still give you some topical videos so at least you have something on this channel to watch. So today I kind of want to talk about something. On Reddit I saw this picture It’s a hypothetical Picture of what the world would look like if all the land and water was inverted on planet Earth. It really kind of got me thinking how would a world like this function It’s not immediately easy to understand because you kind of have to think upside down And you have to kind of study the oceans topography more than the dry land. First of all the strangest thing about this planet is that all the land would be interconnected in every single Cardinal direction.That means theoretically you could circumnavigate the entire Globe by walking in either North to South or East to West Avoiding every major body of water. That means the entire planet would technically only have one big major continent with large island clusters which are the inland Seas like the Caspian Sea, the Black Sea or the Great lakes. The Mediterranean Sea would look like an island but it would still be connected by that very narrow strait of Gibraltar which would now be the Gibraltar Isthmus I guess. The Gulf of Bothnia would be like the weirdest peninsula, like, connected by a bunch of splotchy leakey isthmus What’s the plural Isthmus? When thinking like this you have to realize: Mountains become trenches and trenches become mountains. Now in terms of land formations You kind of have to ask yourself, are we measuring by sea level or by ocean floor level and if that’s the case if we ask by sea level than of course the Himalayas would be the deepest Trench However if it’s by ocean level, then Mauna Kea on Hawaii would be the deepest lake!? However, Chimborazo in Ecuador would be the Trench closest to the center of the Earth. All the islands are become lakes and all the lakes would become islands. Lake Baikal would probably be like one of the most remote islands on the planet. This means that Challenger Deep in the Mariana Trench would most likely be the tallest mountain, dwarfing Mt.Everest at about 36,000 feet or 11,000 meters. Bouvet Island would be like the most remote oasis!? We would still have the same tectonic plates but the direction of impact would have to be backwards and inverted as well, so instead of the Himalayas converging to create mountains they would be sub-ducting to create trenches. This means that the Ring of Fire would now become like the; ‘Bowl of Desolation’; as all of the deep trenches have now become really high peaks that would barricade the Pacific Valley below. Now here’s the problem I have with the image. It doesn’t accurately portray the underwater topography of our planet. I think maybe a little bit more of an accurate depiction would be this picture by ‘frans block’ at 3develop.nl. For some reason there’s a large mountain range that splits right in the middle of the pacific ocean creating a rain shadow effect with the desert in the middle of the pacific. That wouldn’t be there. The only kind of rise would be the east pacific Ridge that goes close to South America but then it kind of cuts off. The whole area would be kind of generally flat as the oceanic trenches would be the only mountains in the area, as all the pacific islands would be like lakes. There’s the coolest thing the longest mountain range on this theoretical planet would be the Mid-Atlantic Range which bisects the entire planet from the Arctic to the Antarctic. The coolest thing is that this new planet would have like a triple convergence mountain range with the Mid-Indian, Southwest and Southeast Indian ridges all smashing into one. I don’t think I agree with the amount of ice on this planet and obviously I don’t believe that the new Lake of Greenland would be all blue half of it most of it would probably still frozen underwater. Also I hate the fact that this is a Mercator projection. I can’t stand the Mercator. It’s so disproportionate it just drives me crazy! Another interesting thing to grasp would be the concept of Continental Shelves. At some point in our geological history the Continental Shelves were exposed and had life on them during the Ice Ages. Over time water levels rose and concealed them And that’s why today we have offshore oil deposits. In an inverted world I guess that would mean that the continental shelves would have been covered first and then later exposed. Sort of like those areas in Egypt where you can find whale bones in the middle of the desert. And then you kind of have to ask yourself, like, how would this work function and could even sustain life? We always tend to kind of err on the side of: “Oh, well, if it has water than of course!” But there’s a lot of other things that kind of go into the mix this is where you kind of have to think scientifically. Our planet right now is about 70% water and is able to kind of sustain a meteorological atmosphere which allows condensation and precipitation of water to lands across the planet. If our planet only had 30% water would it be able to sustain that much precipitation and condensation. I don’t know! Let’s assume that all the oceans on this new planet are saline just like our oceans, and if that was the case then where would all the fresh water come from. Would they come from the ice caps on the tops of the mountains and if that’s the case if we can’t get enough precipitation and condensation would there even be enough ice on those mountain caps? I don’t know! Would any or all of these mountain ranges create a rain shadow effect, creating an entire desert landscape across half of all the land? I don’t know! It’s hard to say because we can’t recreate the scenario in a controlled environment because we’re talking about a planet. We can’t.. ..recreate a planet! We can theorize and it’s fun, but until then it’s just kind of like brain candy. And there’s a lot of other things you have to kind of consider like; ‘What would caves look like? Would they be like underwater pocket reservoirs? And what would a sinkhole look like? would it be like an underwater land pipe? What would the role of marshes and swamps look like? I mean what they still remain but still be a little backwards? I mean also what would Antarctica look like? I mean it would still kind of be frozen but what the land still be water? And how does the ice look like? It’s confusing! And let’s assume that life can thrive on this planet, ‘what would culture look like?’ and ‘how would people live and thrive in what areas and what type of resources would they have?’ I don’t know what do you guys think. Let me know? Write some stuff in the comments and debate about it, fight about it, argue about it. Troll each other about it. Geography, more like geogra.. FIGHT, FIGHT, FIGHT! But in the end the point is is that we live on this planet the way how it is and I kind of like it I kind of like the way how our planet is. So that’s it for now. Thanks for joining me on this hypothetical quest. Subscribe if you want, and I hope you have a good one!

    Don’t Trust Prince Ea (Diss track)

    December 6, 2019


    Hi! I’m Dave from Boyinaband! Recently, I was looking around the Internet when I found a video telling me “You are not depressed!” “Stop it!” with an angry looking guy in the thumbnail who I recognised This is Prince Ea He’s a Youtuber and rapper who has more recently started making content which is motivating and inspiring according to himself You’ve probably seen some of the more successful stuff on Facebook His spoken word videos have gone freakin’ crazy viral Now at first glance, it looks like he’s spreading a good message but underneath the surface there are some really fundamental things he’s doing which struck me as seriously dodgy and watching the video behind the angry thumbnail pushed me over the edge so today I’m calling out Prince EA on several things I think he’s doing wrong First, that video okay so it´s obvious clickbait and that’s understandable we’ve all gotta do what we gotta do tocompetewithbuzzfeed youknowwhatI’msayin But the problem I have is within the content Did he just say that? I’m so mad I’m seriously going to go off on this guy in the comments How did he know? Okay I’m gonna have to stop you there No. Depression does not always go See it looks like you’re mixing up this wikipedia page with this one “depressed” can be a mood like sadness or frustration but “depressed” can also refer to major depressive pffffrickinghair major depressive disorder a mental disorder people are genetically predisposed to I’ll let this professor from Stanford University explain it It’s a biochemical disorder with a genetic component in early experience influences where somebody can’t appreciate sunsets and that’s what this disease is about Seriously well worth watching the full thing small Hagrid has some great insight so let’s see what else Prince has to say If you have to tell someone something is life changing then it probably isn’t that life changing Okay I get what you’re trying to say if you treat your emotions and thoughts as if you were a passive observer you’re more likely to be able to live with them this is at the core of a type of scientifically backed therapy which my therapist did called ACT I actually e-mailed one of the people who created the therapy Steven Hayes sent me a bunch of studies with evidence of it being effective but there are a lot of people who are stuck with brains that do not let their sadness go and this is why this part of his video is so problematic For those people who have the mental disorder it’s like saying to someone in the middle of a heart attack ‘You don’t have heart attacks you may be experiencing a heart attack but you do not have heart attacks heart attacks come… they go….’ And judging from the comments it’s not just me who felt strongly about this In fact one of his fans uploaded a response video which really explained this well First of all thank you for being an increadible force for change it’s fantastic but uhm dude if this is depression and you had been in my house yesterday I would have thrown the fucking thing at you it’s not a choice that people make it’s a shift in perception that’s caused by or has it’s basis in biochemistry What you’re saying now I think almost even errs on the side of being a little bit dangerous for folks
    [hard to hear, someone please check] But I thought I’d give him the benefit of the doubt maybe he just messed up once with this topic until I found another video where he mentions the same concept with some more mistakes See this world we live in it creates depression For the mood: yes. For the mental illness: no. Sunsets This is where the damaging part comes in See everybody suffers from depression There’s always this little voice between the lines there of “Come on, pull yourself together” “we all deal with this sort of thing” This video is going to encourage that voice in depressed people which makes them feel inadequate everyone else has a come and go but not me That’s the kind of thing that could contribute to the statisticky reference at the start of this video Did you know that in ten years depression will be the leading cause of death Hang on, really? Even over heart disease or cancer? That seems really freaking high let me check your sources oh wait, there isn’t one wait is it here? no what about under here behind this? HERE? WHETHEHELLISIT? and this is the next problem The guy references studies all over the place I read a study yesterday Studies show the There was a study done a hospital study At a rate of 40 football fields every minute But I can’t find his sources any fricking where not in the description not on his Facebook posts not hidden in the background of his videos WAIT WHAT’S THAT oh it’s just bigfoot false alarm *AHAAAH* So I have no idea whether what he’s saying is just made up like in his video ‘Can We Auto-Correct Humanity?’ did you know the average person spends 4 years of his life looking down at his cellphone wow really? well i’d love to research this to contribute to the conversation but I can’t because you don’t CITE THE FRIKIN’ SOURCE And this made me wonder just how much scientific misinformation is this guy just casually throwing out there so I started to check Studies show the attention span of the average adult today is one second lower than that of a goldfish Now this struck me as absolute crap and it turns out that that’s because it’s absolute crap The closest I could find to a source that he might be referencing was a marketing brochure saying: The average time a user spends to digest information has decreased significantly over the past twelve years from 12 seconds in 2000 to 8 in 2012 less than the average attention span of a goldfish and after hours of searching I couldn’t find the actual study at all but even if we put aside for the moment the fact that he’s citing a study that doesn’t seem to exist it still means absolutely bugger-all because the study measured how long internet users spend on each page before moving on to the next one it might show that websites load faster now or that there’s more crap on the internet that we have to wade through before finding the good stuff But it does not show that people are incapable of paying attention to important messages which the next part of the video suggests so if you wanted a few people or aquatic animals that have yet to click off or close this video congratulations CONGRATULATIONS And not only did he mess up the part about human attention spans but the goldfish part is also wrong here are two studies proving they can remember things for months and if that’s not your thing even fricking mythbusters did an episode proving it wrong Thirty seconds I think is pretty good to make it through four holes it’s clear that they’ve learned and and it’s clear that they do, in fact, have a memory longer than three seconds MYTH BUSTED I just don’t know how many more layers of wrongness it’s possible to pile onto one sentence except maybe this one. Now that one was just a random fact trying to strengthen his point but some of the things he claims have worse consequences A line that made me fricking shake with frustration was: Videos are 6 seconds at high speed And you wonder why ADD is on the rise Okay so as you might say: Now here I know you didn’t do any research not just because you called it ADD when it’s been known in the psychological community as ADHD since 1987 but also ADHD is one of the most fricking genetic mental disorders I contacted one of the worlds leading ADHD experts Dr. Russell Barkley who told me that and then explained: 70 to 80% is the result of differences in genetics across the entire population it exceeds the genetic variation in any psychological trait if you have an identical twin with ADHD the risk to you is 75 to 90, 94 percent roughly So does watching short video cause ADHD? But we found no real evidence of purely social factors that can explain this disorder it really behaves very much like a biological trait ADHD is fricking horrible it’s essentially being trapped in your own brain unable to control yourself like normal people can this guy is spreading a lie that people could avoid it if they just stopped using their phones rather than the truth that it is one of the most treatable genetic disorders with medication and this from a guy who (according to himself) is “making smart cool” Imma make smart cool again That is definitely not smart and it is definitely not cool So why would he do this? Well if we take a look later in his video it brings me to the final issue with Prince EA Oh Princey! Princey wincey! (Hey! Hey! Hey!) Prince EA makes things seem a lot worse than they actually are so people get emotional enough to share it Mr Zuckerberg not to be rude but you should reclassify Facebook to what it is an anti social network yeah because some people are not using Facebook in a healthy way the entire site which has allowed billions of people to keep in touch across countries is anti-social he gives no sense of nuance to the argument and he often just totally lies technoloGY has made us more selfish and seperate than ever here are several sources which found charitable giving has been growing for decades but I’d love to see what you base your point on but ohwaityouDIDN’TCITETHE SOURCEAANY The news is 140 characters I could have sworn that technology let us freely share our footage and re- the news is 140 characters issues like police brutality which ne- THE NEWS IS 140 CHARACTERS twitter didn’t sto- THE NEWS IS 140 okay okay what else is wrong no longer do I wanna spoil a precious moment by recording it with a phone wanna spoil a precious moment precious moment by precious mo momnet by recording it with a phone I’m just gonna keep them I’ve noticed this is a surprisingly popular opinion but I just don’t get what’s wrong with it what if you wanna share it with someone who couldn’t be there or if you have a bad memory or if, heaven forbid, you enjoy looking at photo’s I don’t wanna take a picture of all my meals anymore I’m just gonna eat them I don’t see the appeal of taking pictures of food either but some people seem to enjoy it what’s wrong with that? just don’t follow them on Instagram I don’t want the new app the new software or the new update well in that case your cyber security is going to be severely comprimised and if I wanna post an old photo hang on you just said you don’t w- The news is a hundred and forty characters oh my mistake and it ends on this big point I imagine a world where we smile when we have low batteries cause that’ll mean we’ll be one bar closer to humanity the implication here is that technology prevents humanity how many films or songs have made you emotional? or how many online conversations made people happy your own videos judging from the response made people emotional which is very human and he went even further in another video entitled “Why I Think This World Should End” Technology has given us everything we could ever want And at the same time, stolen everything we really need really nee-need really nee-
    NEED Frinkin’ everything around us is technology easily accessible food your frickin’ polo shirt What’s the cut-off point for you? 1846? Was the penny farthing a step too far? wat?! He continues to monger fear It’s easier to find a Big Mac than an apple. No it isn’t, there are more supermarkets than McDonald’s. Where are you looking for fruit? Also, you can get apples at McDonalds, just ask. When you find the apple, it’s been genetically processed and modified We’ve been genetically modifying things for centuries Bananas used to look like this Do you want that? Do you wanna eat that Prince Ea? There’s more violence on the screen than ever before And yet it is the least violent period in human history Today, we are probably living in the most peaceful time in our species existence Death rate goes down from 65,000 in the 1950s to less than 2,000 deaths in this decade There’s so much of this crap He makes it seem like the world is getting worse and worse when in a lot of ways we’re improving but that’s not a sharable poetry video is it? Now this point i have made me stop thinking this could be just unintentional and made me question if he respects his audience at all So on Facebook, different post types get different promotion by Facebook’s algorithm so Facebook can make the most money Things which keep people on the site for longer are promoted Like videos and posts and links which take people off the site don’t Which is why upload most of my videos to facebook directly rather than just linking to the youtube video and Prince EA does this himself by uploading video to facebook and youtube separately Now I noticed something weird on Prince E’s facebook Very often he linked to articles externally instead of making posts directly on facebook Now I wondered why he wouldn’t just post directly to facebook or stick to the motivational quote pictures which he slaps his name on to get a bit more exposure then I realized that most of the articles were from the same few websites most were plastered with ads and some were focused with selling something when you see what this clickbait crap is it gets worse I found this article written for Prince EA whatever that means on this site titled 6 signs you are in the presence of a deceased family member They get money by lying to desperate grieved people and spamming their pages with ads I might understand if this was a few articles which he had made a mistake about but this is systematic, it’s fricking daily! So I wondered hang on, is he getting paid for this? Isn’t he supposed to disclose when he’s getting paid to endorse something So I looked it up, In America, which is where he’s from The FTC regulates how legal this stuff is I found the FTC guidelines saying But maybe he actually is just sharing articles regularly which decreases his facebook ranking and potential audience growth Until I saw that some of them were written by him and the FTC guidelines also had a q&a section which had this part Either he’s writing a lot of unpaid clickbait articles or he’s making money by misleading his audience everyday and as he’s said repeatedly he’s really smart *rapping* imma make smart cool again or perhaps I missed something which is entirely possible but it seems seriously fishy to me One of the most frustrating things about all of this is that fundamentally I like that he’s trying to do good in he world he clearly makes a lot of people happy and inspires even if he does say so himself and has raised some great awareness with a few of his videos but these vague generalizations with no scientific backing just make it impossible to trust what he’s saying and what’s worse is there are plenty of other issues that he could address which are a lot less vague and still incredibly important since Prince EA has called out individuals in the past to give constructive criticism I thought this might be the most appropriate way to address him *music playing* *rapping* I read a study the other day It said be careful when you’re listening to prince EA Not gonna cite it in case you criticize it but let me try to summarize it anyway It said if some guy makes wild unsourced claims and never provide citations for what he states and tries to drum up fear over what’s not a big deal then be skeptical as hell of what he’s saying calling everyone’s depression the same are you insane? Guess not, or at least one psychiatrist would’ve explained it can’t always just be thought out, Jesus, it’s chemical imbalance please first do some research And saying ADD is caused by media consumption You kinda hard to trust with such incorrect pressumptions A mountain of evidence is that it is gentic And man, it’s AD /H/ D, don’t you listen to Kendrick? You won’t record precious moments on a phone? I suppose you hated the moment you posted this photo with Oprah you hippy hypocrite But a back-track lickety-split Deleted all of it quick We’re causing society’s downfall! Technology’s out to get us, Put down your phones, they’re devious Oh, and before you do, Follow me on social media. You hate media overstimulation, Wait, look… How many spam articles are you posting on Facebook? But I’ve got to give congratulations… For picking a videographer good enough to distract from the inaccurate crap you’re saying. Fear-mongering over the state of the world to seem clever When several of the things you said are better than ever We are way less selfish And we’re safer than historically And what made that possible? Oh yeah, technology. Human curiosity, man that is humanity What isn’t is spreading misinformation that’s damaging! Now I’m not perfect, I bet I have some citations missed. But I try to be consistent, and if it isn’t, then I’ll fix it. I like your aim to bring attention to important issues, And if you fixed things, you’d be great. Hell, that’s why I thought to diss you But if you won’t listen to me, Maybe you’ll listen to one of your fans who left this comment trying to help you understand saying “Even though I really like your thoughts and attitude, gonna unfollow ’cause of clickbait ads and lack of scientific proof.” Peace.

    Animal Track Detective! | Science for Kids

    December 1, 2019


    Hey Guys! Squeaks and I were just outside, playing in
    the mud! [Squeaks squeaks] It’s wet out there, and wet weather can
    make a lot of mud. Mud’s fun to play around in, but what I
    really like about it is that it’s great for spotting animal tracks! When it’s really muddy outside, I like to
    see how many tracks I can find, and try to guess which kind of animal made which track! We look at animal tracks for fun, but some
    people do it as part of their job! Checking out animal tracks is really important
    for scientists who study animals. That’s because tracks help scientists understand
    where an animal lives, when it travels from place to place, if it moves in groups or by
    itself, and a lot more. You might even say that these scientists are
    kind of like detectives, and the tracks are their clues! But you need special skills to tell one kind
    of animal print from another! You see, not all tracks are alike. Different animals leave behind different tracks. And you won’t just find tracks out in the
    woods — Animals live everywhere, even in big cities! So you might be surprised by how many different
    tracks you’ll find if you look hard enough! But where exactly should you be looking, when
    you’re searching for animal tracks? Well, one good place to start is … mud! Animal tracks show up really well on wet ground,
    so look for muddy spots near water, or after a good rain shower, or when snow has melted! Some tracks show up nicely in snow, too, or
    in dry dirt, but when scouting for animal tracks, remember—mud is your friend! Next, after you’ve found a track—or several
    tracks!—it’s time to start asking some questions. How many tracks are there? Which way are they going? What are they shaped like? And, maybe most fun of all, which animal might
    have left them behind? Let’s take a look at this track. If you see a track that’s paw-shaped and
    has four or five toes, it’s probably been left by a mammal! It could be a dog—like these—or a cat,
    like these. If you ever see a track in the mud that looks
    sort of like a dog or cat track, but is much smaller…say, hardly larger than a penny,
    then you’ve probably found a squirrel track, like these. But of course, mammals aren’t the only animals
    that leave tracks behind. One of the most common animal tracks you’ll
    see is this one: a deer track. Deer tracks don’t look like pawprints, do
    they? Do you see those two large, curvy marks? Those are the two halves of a deer’s foot,
    called a hoof. Each half leaves a mark that looks like a
    tiny horn, with a point and the top and a small spot at the bottom. Now, what if you find fork-shaped tracks,
    like these? Well, they’ve probably been left behind
    by a bird! Birds, deer, squirrels, dogs, and cats are
    some of the most common animal tracks you’ll find when you’re playing animal track detective. So, do you think we’re ready to play? Let’s test our track-naming skills! I’ll show you a track, and you guess what
    kind of animal might have made it, based on what we just learned, OK? OK! Here’s track number 1. What do you see? It looks like a paw, right, so it’s probably
    a mammal. Good! But it’s a really small track. Smaller than even a little house cat might
    leave. I’m going to guess “squirrel.” Yay! It is a squirrel track! Time for track number 2. Hmm. This is not paw-shaped. In fact, it’s kind of…fork-shaped. Definitely not a mammal. Do you remember what kind of animal makes
    fork-shaped tracks? A bird! I guess this is a bird track. It is! OK, last track. Ready? Not paw-shaped. But not fork-shaped, either. Sort of … horn-shaped? And it’s split into two halves. …a deer! These are deer tracks! Great job! Like I said, these are some of the more common
    tracks you might find in the mud, snow, or dirt, no matter where you live in the world. But there all kinds of animals in the world,
    and each leaves its own special kind of track. So, if you study them enough, one day, you
    might be able to tell the difference between two different kinds of birds, or two different
    kinds of cats — just like some scientists can! And we didn’t even get to cover reptile
    tracks or insect tracks. So maybe we’ll get to those another time
    — on the next muddy day! In the meantime, thanks for playing Animal
    Track Detective with us! And remember, if you have a question about
    tracks or anything for us here at the fort, let us know by leaving a comment or emailing
    us at [email protected] We’ll see you next time!

    How cookies can track you (Simply Explained)

    How cookies can track you (Simply Explained)

    November 27, 2019


    So we’ve all heard how companies like Facebook
    and Google can use cookies to follow us around the internet and keep track of what we’re
    interested in. They do this to sell targeted ads or in some
    cases even share that data with others without our permission. In recent months, there has been a lot of
    fuss around the fact that Facebook tracks its users across the internet. So how do they do this? Before we dive in, let’s look at what cookies
    are and why they exist. Let’s start with some quick history. The cookie was created in 1994 by an employee
    of Netscape Communications, the same company that made the browser. He was creating an online shop, and he didn’t
    want to store the contents of the shopping cart on the server. Instead, he wanted a way to save it on the
    computers of the visitors, right until they made their purchase. The reason for this is simple: if the server
    doesn’t have to keep track of everyone’s shopping cart, it has less work and can save
    money. In 1994 the Netscape browser implemented cookies
    and the next year Internet Explorer followed suit. However two years later – in 1996 – the first
    concerns were raised when it was discovered that cookies could potentially invade our
    privacy. That would turn out to be very true, but we’re
    getting ahead of ourselves here. Let’s take a look at how cookies work. Let’s imagine we have a website that requires
    people to log in to see the contents of the site. When you log in, your browser sends your username
    and password to the server, who verifies them and – if everything checks out – sends you
    the requested content. However, there is a small caveat. The HTTP protocol – which is what we use to
    browse the internet – is stateless. That means that when you make another request
    to that same server, it has forgotten who you are and will ask you to log in again. Can you imagine how time-consuming it would
    be to browse around a site like Facebook and having to log in again every time you click
    on something? So cookies to the rescue! You still log in to the website, and the server
    still validates your credentials. If everything checks out, however, the server
    not only responds with the content but also sends a cookie to your browser. The cookie is then stored on your computer
    and submitted to the server with every request you make to that website. The cookie contains a unique identifier that
    allows the server to “remember” who you are and keep you logged in. As you can see, cookies are very useful, and
    they make our lives a lot easier. But it doesn’t stop there! Besides keeping you logged in, cookies can
    also be used to store your settings. Let’s say you change the number of results
    your favorite search engine should return. Chances are high that they save this preference
    in a cookie and not on their servers. But there are also some restrictions on the
    use of cookies. Most browsers only allow websites to store
    a maximum of 300 cookies and they cannot contain a lot of data (just 4096 bytes). The biggest limitation, however, is the fact
    that cookies set by one website, cannot be read by another. And that restriction raises the question:
    how can companies use cookies to track us around the internet? Especially if a cookie from one website cannot
    be read by another. How can Facebook for instance track what sites
    we visit? Well, the whole process starts when you log
    in to Facebook. To remember that you’re logged in, Facebook
    stores a cookie on your computer, nothing unusual about that, many other sites do the
    same thing. This cookie is scoped, or bound to Facebook’s
    domain name, meaning that no one else besides facebook.com can read what’s in the cookie. Let’s now imagine that you browse away and
    you land on someone’s blog. The blog cannot read your Facebook cookie,
    and the scope prevents that. Facebook also can’t see that you’re on
    this blog. All is well. But let’s now assume that the owner of the
    blog places a Facebook like button on his website. To show this like button, your browser has
    to download some code from the Facebook servers, and when it’s talking to facebook.com, it
    sends along the cookie that Facebook set earlier. Facebook now knows who you are and that you
    visited this blog. I’m using Facebook as the example here,
    but this technique is used by many other companies to track you around the internet. The trick is simple: convince as many websites
    as possible to place some of your code on their sites. Facebook has it easy because a lot of people
    want a like or share button on their website. Google also has an easy job because many websites
    rely on its advertisement network or on Google Analytics. At this stage, cookies are getting out of
    hand. I read the cookie policy of a few popular
    websites. Here is an overview of how many cookies they
    expose you to. Reading some tech news on CNET: 100 cookies
    Finding a song on last.fm: 82 cookies. Reading The New York Times: 57 cookies
    Finding a job or connecting with your network on LinkedIn 28 cookies. And then some companies take it to the extreme. The company behind Yahoo mentions that their
    websites could use up to 455 third-party cookies. 455! That’s just outrageous! Granted, not all of these cookies track you
    around. In fact, a handful of them are essential for
    the site to work correctly, like a session cookie to remember that you’re logged in. However, the majority of cookies on these
    websites don’t serve the user. They are there to track you or to display
    more targeted ads. So what can we do to prevent these cookies
    from tracking us on the internet? As a user, you can protect yourself from trackers
    by installing a browser extension that blocks them like Privacy Badger or Ghostery. You could also switch to a browser with built-in
    privacy protection tools like Brave or Safari. And if you don’t want to do anything, the
    law is on your side. More and more politicians realize that cookies
    are a threat to privacy and that the use of trackers should be regulated. In Europe, we have the GDPR which requires
    websites to be transparent about their use of cookies and requires sites to offer users
    a simple way to opt-out. You’ve probably seen these annoying cookie
    banners asking for your permission. Next time you see them, don’t just click
    on accept but look at what cookies the website wants to place on your computer and for what
    purpose. So to summarize: cookies were invented to
    make our lives easier and allow us to stay signed into websites or remember the settings
    that we changed. However, the downside is that cookies, along
    with other techniques, can be used by large corporations to follow us around on the internet
    and gather data about us that they can potentially sell to others. I hope you found this video interesting and

    KY Dept of Education and Interapt TRACK Partnership Announcement

    November 26, 2019


    Hi I’m Steven Pruitt, Commissioner of Education
    for the Commonwealth of Kentucky. I’m joined here today by Ankur Gopal of Interapt. We are here to have an exciting announcement
    about a great opportunity for our students in our TRACK program. For the first time, we’re going to offer an
    Information Technology Apprenticeship. It’s a 2-year pilot for select schools that
    are going to allow our students to engage in computer programming apprenticeships. This is going to be incredibly important opportunity
    for our kids, for our employers, and for our state. Wouldn’t you agree, Ankur? Yes, Dr. Pruitt, it is. And Interapt is very proud and pleased to
    help be part of this solution. By the year 2020, there will be over 10,000
    open technology jobs in the Commonwealth of Kentucky. In fact, many businesses are already struggling
    to fill in these roles with skilled developers and IT team members. As a partner in the first IT TRACK program,
    we’ll be able to introduce high school students to this fast-paced tech industry. They will learn how to use their skills to
    develop projects, work in a software development lifecycle, and participate in the gig economy. Those who successfully complete the pre-apprenticeship
    program will have the opportunity to apply at Interapt after graduation. If accepted to our apprenticeship program,
    they will be credited for up to 500 hours toward their apprenticeship completion, get
    paid to train, and receive a nationally recognized credential from the U.S. Department of Labor. But don’t take my word for it though–meet
    Brian Keinsley, Enterprise VP of Information Technology at Humana. Thanks Ankur! At Humana, we’re excited to hear about TRACK. We intend to take a good look at the job applicants
    who have completed this program, and be sure to follow the ones who go on to complete the
    Kentucky Registered Apprenticeship. We believe these individuals will have proven
    they are hard workers and are passionate about working in technology. We hope to be hearing great things about these
    students in the future! Pairing this type of blended learning with
    an apprenticeship program will give students, parents, and educators the opportunity to
    look differently at post-secondary education. Additionally, it will give students the skills
    they need to be competitive in a local and global job market, as well as participate
    in the upcoming gig economy. We really look forward to seeing the outcomes
    of this program and sharing those with you in the fall of 2018. Thank you so much, and we are so excited about
    this brand new program!

    NASA’s zero-gravity plane: How astronauts train for microgravity | Michelle Thaller

    November 21, 2019


    ack, you had the question, how do we remove
    gravity from the anti-gravity chambers that astronauts train in? And you’ve probably seen films of astronauts
    in training, floating around in a closed chamber. And it does kind of look like we may have
    something that can actually shield against gravity. Well, for one thing, I really wish we did
    because just think about how useful that would be. Think about having, say, a construction site,
    and you can remove all of the gravity. You could actually move things around really
    easily. There’s so many applications for having some
    sort of anti-gravity device, but we don’t have one. There is no way to shield astronauts here
    on the earth from the We train astronauts by putting them up in an airplane and then
    having the airplane fly very, very carefully on an arc to throw everybody up at just the
    right rate so they’re floating. It may have actually happened to you. You may have been on an airplane, and the
    airplane actually sort of arced around, and you felt yourself thrown up a little bit. So that’s actually what we do in a very controlled
    way. We only can get about a minute’s worth of
    weightlessness that way. The airplane flies in arc and then goes around
    again and flies another one. So the astronauts train by doing this over,
    and over, One of the really amazing applications of this was in the movie Apollo 13. If you look very carefully, it’s a very realistic
    depiction of astronauts floating around in the weightlessness of space. And that’s because they really were weightless. They actually put movie sets inside this aircraft
    and filmed one minute at a time. The footage of the astronauts floating around
    the lunar module, for example. Now, this sort of training where one minute
    you’re weightless, and then all of a sudden you’re not, and then you’re weightless again
    has a bit of an effect on people’s stomach. And, in fact, the NASA nickname for this plane
    is the Vomit Comet. It’s something that can actually make you
    feel pretty sick to your stomach, but a lot of astronauts in training also find it really
    fun. And I’ve heard it mentioned that there are
    some pilots that are better than others at doing just the right arc. There are some pilots that as you fly, you’re
    up against the ceiling, up against the floor, up against the ceiling. And then there are ones that get really, really
    smooth so you have the longest possible time in weightlessness. And, in fact, I heard that the pilot that
    was best at it would actually put a pencil in front of him as he began the arc to make
    it feel like you were weightless. And then he would fly the plane around the
    pencil, trying to keep that pencil in the same position as you went through the weightlessness
    arc. So there’s no way we can shield from gravity. We only can train astronauts a minute at a
    time in these aircraft. The other way we train them is by simulating
    a weightless environment the best we can by using water, by using really, really big swimming
    pools. At the Johnson Space Center– one of my favorite
    places to go in all of NASA– there is a swimming pool, a pool so big that we actually have
    an entire scale model of a space station underneath the water. The same size as the space station. We put astronauts in basically scuba gear. They have their helmets. There’s air being pumped through there. And they can float around and practice doing
    spacewalks outside the space station in the water. And then all around them, there are actually
    real scuba divers, ready to assist them to make sure everything’s going well. And I’ve had friends who have actually served
    this way. They’ve actually been scuba divers that help
    astronauts train. So, unfortunately, there’s no way to shield
    from gravity here on the Earth. Gravity is of curvature of space and time. We have no way to manipulate that with our
    current technology, so we have to fake it. Astronauts have to either be in aircraft that
    are flying arcs or pretending to be weightless under the water,
