Once upon a time, your ancestors used to look at the night sky to determine their location. Then we used a Thomas Guide, remember those? Today, it only takes one magical technology to get driving directions, send your picnic spot to a lost friend, or track how far you’ve gone during a workout. That technology is called GPS, and you’re about to find out the secret behind it. Did you know that GPS was actually a military invention? The highest quality signals were only used for military purposes until May 2000, when it became available to all civilians for free. Now GPS is literally everywhere, and you can now even purchase GPS insoles to keep track of your kids or relatives with Alzheimer’s disease. Other videos you might like:

And here’s a Bonus 8:05 #GPS #inventions #brightside Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY:
– To put it simply, GPS is a system that has three basic parts: satellites, ground stations, and receivers.
– Grounds stations use radars to find out if the satellites really are where they’re supposed to be. – The GPS system has 32 active satellites orbiting the Earth. 24 of them are core satellites, and the rest serve as emergency replacements when something happens to the others. – A receiver on Earth has to see at least 4 satellites to calculate an accurate location because the GPS uses a trilateration mechanism. – 2-D trilateration is about calculating its latitude and longitude position on a map. – When it comes to 3-D trilateration, it’s basically the same, but there’ll be spheres instead of circles on your drawing. 3-D position includes your latitude, longitude, and altitude.
– GPS satellites send information about their position and current time to a GPS receiver at certain intervals. The receiver gets the information in the form of a signal.
– GPS satellites have atomic clocks that keep the most precise time, but it would be impossible to install these clocks in every receiver. – Satellites’ atomic clocks get 38 microseconds ahead of ground clocks every day. If scientists did nothing about it, GPS locations would be off by 6 miles more every day. – There’s also a GPS almanac in the receiver that keeps track of where this or that satellite should be at any moment.
– GPS not only determines the most accurate location of people and objects, but also sends time signals that are accurate within 10 billionths of a second.
– Even though it’s incredibly accurate and useful, sometimes GPS takes people to unexpected places, especially in rural areas. Subscribe to Bright Side : https://goo.gl/rQTJZz —————————————————————————————-

There are numerous workouts that target each and every of your muscles, but there’s none better for your stamina and endurance than planking. If you think plank is a static exercise with little dynamics, then think again! Thee are different variations of plank that will bring your exercise routine to a new level! The standard plank strengthens your core, abs, and back. As you progress, it’ll become easier to perform, so when you’re ready, increase the time you hold the position: first to 45 seconds, then to a minute, and so on until you reach 2 minutes. The same applies to the rest of the planks you’re going to see in this video, so just hold it! Other videos you might like:

– Tom Cruise plank, or a Spiderman plank, if you like is all about training your entire body: shoulders, forearms, calves, thighs, and abs.
– Side plank with foot touching is awesome for your shoulders, arms, and hips.
– While you’re still in the side plank position, it’s a good idea to switch to knee to elbow side plank that targets the same muscles as the previous one and adds another group to them: your glutes. – Plank sidewalk is a lighter exercise to give you a little breather before the tough stuff. It targets mainly your back and shoulders.
– One-armed plank is not exactly for beginners, so don’t feel frustrated if you can’t hold it even for 30 seconds. It will make your core and especially your shoulders burn.
– Plank side jumps works wonders for your hips, glutes, calves, abs, and back. It also acts as a moderately effective cardio exercise, getting your heart rate up, which is always nice. – Leg lifting plank is a mix of planking and stretching, which helps you avoid injuries and do some endurance training at the same time. Leg lifting plank targets your obliques, glutes, and latissimus dorsi, or the biggest back muscles, nicknamed “lats”.
– Forward slide plank will train your calves, abs, and biceps.
– Cross-step plank is another plank variation that gets your muscles stretched while strengthening your core, back, and legs.
– PPT stands for posterior pelvic tilt, which probably still doesn’t make any sense. Anyway, what this exercise is about is building a lot of tension in your core, activating your abs like nothing else. Subscribe to Bright Side : https://goo.gl/rQTJZz —————————————————————————————-

Did you know you could sell a $20 bill for ten times its value? Or that a person you’re physically attracted to may not be as smart and funny as you think? Or that the only reason why there’s this third option on the market is to create the decoy? All these things are called cognitive biases, and they rule your entire life without you even knowing it. Here are some of the most prominent ones. Other videos you might like:

Framing effect 5:00

Dr. Fox effect 7:45
Spotlight effect 9:17 #psychology #humanbrain #brightside Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY:
– How hard could it be to take 20 bucks from an MBA student? In fact, Professor Max Bazerman proves it’s easy-peasy. In 2010, he first conducted an experiment at his class where he organized a simple auction: he would give a $20 bill to the student who pays the most money for it. The $20 bill was sold for $204.
– The only reason why there’s this third option on the market is to create this decoy to make you buy a more expensive product.
– You may not notice this, but when you see an attractive person, you tend to exaggerate their good traits of character. And that’s the gist of the halo effect.
– We tend to prefer an option that is described in a positive way. Even if the only other option is absolutely the same, people will likely disregard it because it’s been given a negative description. – Although a situation can be completely random, people tend to think their choice somehow affects the results. We like to be in control of everything, don’t we?
– The positive attitude and liveliness of a person can completely fool a whole audience of highly educated specialists. If you ever heard motivational speakers and got inspired by their ideas… well, chances are that you’ve also experienced the Dr. Fox effect.
– If you’ve ever felt self-conscious leaving your house in different socks, worrying that everyone would laugh and point fingers at you, you’ve become a victim of the spotlight effect. It’s a psychological bias that basically makes you think too much of yourself. Subscribe to Bright Side : https://goo.gl/rQTJZz —————————————————————————————-

More 7 Psychological Effects That Rule Your Whole Life Videos

They say success is a mindset. No offense to whoever “they” are, but that doesn’t really help most people much. So what about a real-life example to live by? If you've got problems with procrastinating, feeling overwhelmed by all the stuff you need to get done, and just overall pitiful time management skills, this is what can help you. Okay, now, who's one of the most successful and productive dudes out there? You're right! It's Elon Musk! This guy is a productivity ninja who’s mastered the art of time management. He heads multiple companies, the most well-known being Tesla and SpaceX, and has admitted that he works 100 hours a week or more! Let's try to follow his typical schedule for a week.

The fun part – the weekend! 6:58
Some conclusions 7:35 #elonmusk #success #brightside Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY:
– I started on a Sunday evening by planning my week ahead based on what I’d read about Elon Musk’s routine. Much to my dismay, the first thing I found out is that he wakes up at 7am every single day and functions on just 6 hours of sleep!
– I’m a pretty traditional guy – I like to get my recommended 7-9 hours of shuteye each night, so 6 hours was not enough.
– Elon Musk skips breakfast… Well, at least he drinks coffee! To be honest, the first couple of days with no breakfast hit me hard. – One of Musk’s golden productivity rules is to work in a 5-minute block system, which means that for 5-minutes, I had to stay completely focused on one thing and then switch to another. – Some of my projects take hours to finish. But by breaking them down into smaller steps that I spent less time on, in the end, it took me fewer hours to get my projects done! – The first day, what used to take me a solid 8 hours to do ended up taking me just 6. By the week’s end, I’d cut that number down to 4! – As for phone calls, Elon suggests NOT taking any calls during the day except for emergencies.
– I really saved a lot of time on the email thing. I would’ve never guessed I was wasting so much time going through my inbox! – So, I hit the gym twice this week, and, I gotta say, I think I understand where Musk gets his energy – working out really does charge your battery, so to speak. – Getting 6 hours of sleep is not for me, but I like getting up at 7 and having time to plan my day ahead. So, I’ll hit the sack at 12am to get that precious extra hour of shuteye. – And I’ll spend some of that extra hour on a good breakfast. Even if experts say you can go without, I’d prefer to fill my tank before I head to work!
– Planning the day ahead and tackling tasks in 5-minute blocks will be my new norm.
– I’ll continue ditching my phone during work hours and keeping the emailing at a minimum because this saved me loads of time. – I’m enjoying the gym, and I feel really good! It’s even become a sort of new hobby of mine.
– As for the weekends, I need my Saturdays, man! I understand Elon has a lot on his plate, but I’m no CEO or entrepreneur, so I can afford to take 2 days off a week instead of just one. Subscribe to Bright Side : https://goo.gl/rQTJZz —————————————————————————————-

More I Lived Like Elon Musk for a Week But One Day Was Enough Videos

It was the image that broke the Internet in April 2019. The subject? One that had managed to evade the paparazzi for as long as people have theorized about its existence. It was the first photo ever taken of a black hole! It's a monumental event, not only for scientists but for the public too! Up until recently, black holes had only technically been a theory. Well, astronomers were pretty sure they exist. For decades they’ve been watching the pull and push of black holes that influenced neighboring planets and stars. They’ve even been listening to the powerful gravitational waves that appear after supermassive black holes collide. But up till now, astrophysicists have always lacked that final proof of their existence. Other videos you might like:

Animation is created by Bright Side. #blackholes #space #brightside Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY:
– The event horizon is “the point of no return” on the outskirts of a black hole. Once something, for example, matter, radiation, or light, reaches this boundary, there’s no way for it to escape the black hole's clutches.
-To capture the very first image of a black hole, scientists created a (sorta) mega Earth-sized virtual telescope by combining the power of 8 different radio telescopes spread around our globe.
– What they observed was a monster of a black hole measuring about 25 billion miles (40 bln km) across.
– It’s somewhere out in the middle of the supergiant Messier 87 galaxy, about 55 million light years away from our little floating rock in space.
– The headline-making black hole is a mature one. It's just chillin’, resting, and eating gas that's trickling from nearby stars. The giant is dimmer than other more energetic black holes.
– Black holes are some of the most extreme objects that exist anywhere in space. They pack incredible amounts of mass in a single point, which makes them infinitely dense.
– Black holes are so unique because they're the only existing objects surrounded by a region of spacetime that’s entirely inaccessible for the rest of the Universe!
– Some scientists are sure that certain black holes (the ones that spin fast) can create wormholes in spacetime!
– If scientists can get more images of black holes, they may be able to confirm (or reject) this hypothesis!
– There are tiny ones called primordial black holes. They vary from the size of an atom to that of a mountain!
– There’s a supermassive black hole right in the middle of our Milky Way galaxy!
– Besides Sagittarius A, there are a staggering 100 million medium-sized black holes in our galaxy.
– Scientists have found out that there exist black hole binaries: two black holes that orbit each other.
– If you ever find yourself near a black hole, you’ll notice that time slows down significantly.
– If you managed to squeeze Earth down to the size of a cherry tomato, it would turn into a black hole.
– They also sometimes fling out "spitballs" the size of a planet. These things manage to escape a black hole’s immense gravitational pull by slipping away before going past the point of no return. Subscribe to Bright Side : https://goo.gl/rQTJZz —————————————————————————————-

More The First Ever Black Hole Image Finally Released Videos

Our solar system is made up of eight planets, hundreds of natural satellites like moons, thousands of asteroids, and billions of comets. This beautiful space cocktail is constantly moving around our sun. But it could all be torn apart if just one stray black hole decided to drop by… Yes, there’s been a lot of talk about black holes lately since Kathrine Bouman figured out how to take a picture of one. The closest black hole to our solar system is 10 to 13 times the mass of our sun, and it’s located 3,000 light years away. But what would happen if a black hole came into our solar system?

13 Scariest Theories That'll Make Your Blood Run Cold https://www.youtube.com/watch?v=E3UIGKn69dE& TIMESTAMPS:
What are black holes? 1:18
Supermassive black holes 1:48
Stellar-mass black holes 2:59
The most terrifying thing 4:11
When we would start to feel its pull 4:49
You want some spaghetti… fication? 5:51
What if two supermassive black holes collided? 6:49 #blackholes #space #brightside Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY:
– Black holes actually huge amounts of matter crammed into a teeny-tiny space. As a result, they have an extremely strong gravitational pull. In fact, it’s so powerful that even light can’t escape once a hole gets its hands on it.
– A big fat star collapses, then boom, black hole. Those ones are called stellar mass black holes. But there are also mega monsters called supermassive black holes. Those ones can be found churning slowly at the centers of galaxies. – If our galaxy, the Milky Way, decided to rearrange itself, putting us a few dozen light years away from the center where a supermassive black hole lives (instead of 26,000 light years away), we’d be doomed.
– But what about a stellar mass black hole? They appear when stars run out of their star fuel and basically fall into themselves. This only happens if a star is big enough, like 3-10 times bigger than our sun. – Here’s the thing I find most terrifying – we wouldn’t notice the black hole until it’s too late! The only detail that could give away the approaching black hole is a slight blurring of distant stars due to the hole’s gravitational lensing effect.
– As the gravitational pull of the black hole approaches each planet, it’ll play tug-of-war with our sun, ripping them all to pieces. As soon as the black hole reaches the asteroid belt between Jupiter and Mars, we’ll start to feel its pull
– Before disappearing into the abyss, anything that falls into the gravitational pull of a black hole will go through a process called spaghettification.
– Basically, if anything gets too close to a black hole, before it falls in, it gets stretched waaaay out (like a spaghetti noodle!) due to the hole’s incredible gravity.
– According to scientific estimations, the odds of a black hole coming across our solar system, much less munching on our planet, are lower than the chance of winning the lottery ten times in a row.
– It turns out that almost all galaxies in the universe have their own supermassive black holes in the center of them. In some of these galaxies, the black holes can be billions of times more massive than our sun! Subscribe to Bright Side : https://goo.gl/rQTJZz —————————————————————————————-
