  • The tame tachometer rationally attract because sneeze generically join about a enormous swan. screeching, guiltless toothpaste

  • I have a question. I had been searching for the answer in the internet. But sadly i was unlucky. So Can you please help and answer the Question. Here's the question : What will happen if both the front tyres of a car of which the front tyres are the tyres which is used for changing direction( I have heard of cars the other way) are turned in the opposite direction ? Like if both are changed towards each other or away from each other. Please if possible explain it with a short video

  • Trying to fly on Mars *is* the experiment.

  • please use kilogram

  • U know when ur in class and everyone’s speaking or shouting when your trying to concentrate and u just want to shout and tell em all to shut up! Just me?

  • Shampoos strip out natural oils and ensure that the hair and skin can’t achieve a healthy balance.

  • problem is, that the chain has also some WEIGHT , which is added to the weight of the dumbbell.. so that is main reason why it accelerated quicker than the free dumbbell 😅😅😅

  • And what if two wheels on stick rotating in oposite directions? What then? On one end or on two ends.

  • good content

  • god i hate imperial so much

  • Don't they have cameras that have 100,000,000 frame rates that can watch light move through a room

  • You can have two mirrored situations. One on each end. Then in addition you time stamp the laser with pulses that are read by the other side.

  • i have an idea of how to measure it but i cant write it in a comment. but... does it even matter if light moves the same? its kinda like "is my purple the same as your purple?" it doesnt matter because we both agree *this* is purple... so i dont really see why it matters? but then again im only a stupid 16 year old on youtube xD

  • I have a few ideas about how to measure the one way speed, so please correct me if I am wrong. First, if you send a synchronizing signal using electricity, you can know that speed and it would not be the speed of light, so can't you use that to find the difference in values. Also, can't you measure the speed of light in relation to other things. For example, what if you blew up a nuclear bomb in a vacuum, measured, with ONE clock, when the massive amounts of light reached the clock (i.e. by turning the clock on at that instant) and then seeing when the protons and neutrons reach. Then, do the same thing but with the clock on another side of the blast. Then you can see if there is any difference in the time measured, effectively measuring if there is a difference in the speed of light in different directions. Finally, can you not use the way that the speed of light was first discovered to be finite? Someone whose name I cannot remember looked at the eclipses of the moons of Jupiter and when they stopped being visible. He noticed that when Earth was farthest from Jupiter, the time that this was seen happening was a few minutes after when it was supposed to happen, and earlier when Earth was closest. If you know the distance of Jupiter at those times, can you not measure the speed of light in that direction? If I am mistaken, please explain how.

  • I fuckin need this

  • The masks are starting to fall off! "The Chinese biology lab in Wuhan belongs to Glaxosmithkline, which (coincidentally) owns Pfizer!" (the one that produces a vaccine against a virus that (accidentally) started at the Wuhan Biological Lab, which was (accidentally) funded by Dr. Fauci who (accidentally) promotes the vaccine! “GlaxoSmithKline (by chance) is managed by the finance department of Black Rock, which (by chance) manages the finances of the Open Foundation Company (Soros Foundation), which (by chance) operates the French AXA! "Coincidentally, Soros owns the German company Winterthur which (coincidentally) built a Chinese laboratory in Wuhan and was bought out by German Allianz which (coincidentally) has Vanguard as a shareholder who (coincidentally) is a shareholder of Black Rock which (coincidentally) controls central banks and manages approximately one-third of global investment capital. "Black Rock (coincidentally) is also a major shareholder in MICROSOFT, owned by Bill Gates, who (coincidentally) is a shareholder in Pfizer (who - remember? He sells a miracle vaccine) and (coincidentally) is now the first KTO sponsor! Now you understand how a dead bat sold in a wet market in China infected the ENTIRE PLANET! "

  • This woke up my cat

  • mirror is not the only solution, two light beams into opposite direction will work as well

  • I want him a my teacher

  • Is anyone else thinking shadesmar?

  • at 3 min - clocks get out of sync not because of special but because of general relativity due to acceleration

  • No, I have not seen the video.

  • It has Gyros, does it have Pita's too?

  • Love the explanation, still most people I know with a sensitive skin have weeks (!) of irritated hair skin after use of head and shoulders, its apparently super aggressive to the skin. My theory (should be interesting to review), is that the use of metaloxides is not controlled and it oxides too much with the skin, thus nullifies the bemefits of better gene expressions results.

  • 15:40, the Nobel Prize techniques reset your cell to an embryo. 15:55, doing that to your entire body would cause it to become a tumor. Takeaway: kids are literally cancer

  • Did he change the title?

  • Very cool thanks.

  • I find this interesting to for some reason it happens to quick but I believe that there will be no another covid 19. But I could be wrong.

  • Bill Gates creates the next crisis. Stop feeding the Snake Oil Salesman.

  • You need to get your sound recording adjusted properly. Some people are feinter and the narrator is too loud.

  • You can measure the one way speed of light, i have done it... you take a length of fiber terminate it to the output of a laser... put a detector at the output of the fiber.. get a fast oscilloscope, trigger on the output pulse and put the laser output pulse on channel 1 and detector signal on the end of the fiber on channel 2. Measure the time difference and correct the speed using the index of refraction of the material of the fiber. The distance of the fiber is known... divide the distance by the index of refraction corrected time. You have the speed of light, one way.

  • Why those shapes with identical sides are familiar to me? Oh yeah, rpg dices, of course

  • It would take years to remove the hair on my back.

  • Do you know how long I've been pronouncing Veritasium as "Veritaserum" from Harry Potter in my head? God, I'm dumb.

  • So you wanna test if the 1 way trip is instant. Cant u Just do from start no clock a light then a mirror going diagonal with a clock that starts going to another place where there is another mirror that sends the light back to the clock and maybe if u want to also back to the 1st clock

  • It's purpose is *not* to make scientific discoveries, it *is* the scientific discovery.

  • I'm sure forced, prolonged silence could cause mental issues. Voluntary isolation in a "silent" room where other senses still are there wouldn't be a problem I'd think. You'll get heightened sense in other senses. The brain relies on sensory for all information, so the first few minutes would probably be a mixture of your brain searching for lost information intake. It'll fill that in with other things. I'd love to meditate in a room like this. lol I want to try a sensory deprivation chamber as well.

  • Quantum Entanglement This would fix your time dealation issue since they spin at the same exact rate no matter the distance.

  • Actually.. you can measure the speed of light... if you couldn't.. laser distance measurements wouldn't work.

  • Why not use a balloon? and also tell where Nasa bought their magic physics elimination wand? please

  • Not correct! 1 Cod flesh is not oily. 2 people further inland ate salmon from the rivers and reindeer, both rich in vitamin D, the laps did not have rickets. 3 The Nordic population in Greenland traded with Iceland, which have a lot if cod. 4 The vikings had vitamin C with them at their long journeys in the form of cloudberrys and lingonberrys. Both very good for long term storage. The polar expedition with Andre' is known for him not getting scurvy as all the other. Now we understand that it was his lingonberrys from his mother that saved him. As propably a viking descendant in Sweden I have seen that old people knew that eating the liver and the rom from cod was important, as well as eating herring, rich in vitamin D. The onset of little ice age oround 1350 made the waters around Iceland and Greenland hard to sail, due to lots of ice. This made trade problematic at the same time as the Inuits was pressing south. The Nordic Greenlanders could not keep their society going unde these sircumstances.

  • Haha u updated the title. Cool!

  • i saw a video by astrogeekz and it said that jupiter yeeted that thing out of the solar system im pretty sure that planet is the one that got yeeted

  • well i would say ligth off is kind of adding to the anxiety, solitary confinement can affect your mental healt after all.

  • ee türk ama ing konuşuyo

  • This is called balls deep.

  • Thank you so much for uploading this video. It is helping me get through the pandemic!

  • What if you use sound as a comparing medium? We know the speed of sound, so turn on a light and make a sound at a fixed distance from a detector, you should be able to calculate the speed of light from the delay between the sound detection and the light detection

  • Masks PROTECT YOU and people around you!

  • why does it look a little lobsided

  • this is very Buddhist. thank you

  • Didn’t know a nuclear bomb could excavate, I thought they blew and made a crater, not excavate it lol

  • At 10:40 if the two clock don.t Start at the same time we can see the difference between two direction

  • Dangererous! making your own futures Is making your god.

  • Aww helll naw Im iN dANgEr

  • Hard to believe these are some of the same people who appeared on the recent NASA coverage of the Mars Rover landing which was just awful as it was done only for 2nd graders, in fact I’m guessing some 2nd graders were rolling their eyes at the horrifically stupid coverage

  • Record is 45 minutes* Everyone reading this: that's insultingly low

  • Stop calling anything a conspiracy when you are not willing to investigate or prove it. It just pushes this fishiness.

  • why didn't they integrate the solar panel into the rotors?

  • The slow mo guys have filled light. What about that.

  • Just realized you were born the same day as Carl Sagan, I'm skeptical towards astrology and all that but it's like you were meant to be a science communicator

  • Everyone’s left ear is enjoying this

  • It has something to do with the ocean, right?

  • I didn’t understand any of this but Im excited

  • I can remain their for ever. I created the same situation at my home but, when every sound gets cut off then I start hearing my heartbeat and my inner sounds so the result is you can't stop hearing unless you are deaf. The more the silence the more bodily sounds get amplified. just like you hear tic tic of clock at night but not during day.

  • He just happens to have a pack of straws on hand

  • The argument of pressure is wrong ! You can solve the clapeyron equation to check out, if this is possible.

  • That totally makes sense that speed of light might be different in different directions because as the universe is expanding, solar system is orbiting the central black hole of the galaxy, earth is orbiting the sun, and earth itself is rotating, we are moving! And even if we agree that in static situations the speed of light should be the same in all directions, it must be different on earth.

  • Absolutely evil person what would you give him sir time, oh you must of been paid.

  • He is not a prophet and can’t predict anything! It’s more possible that he knows something just planned! It’s not impossible for someone so brilliant as he is, to make his efforts in educating people about eating healthier instead of eating bats, cats and dogs! There’s so much to be done in the world in Education. Beginning in America, where the level of Education fell so much recently!

  • There is no room that make you focus on.your study

  • Yes, I do expand when eating too much chocolate.

  • He makes a coaxial helicopter sound so complicated. Haha. My first rc helicopter was coaxial and the easiest thing I’ve ever flown!

  • How can anyone ignore that he confidently said he is FOR depopulation and vacination IS one method?? HE said it HIMSELF.

  • Thor practising with his mjolnir

  • Hear that? It's the sound of your credibility evaporating.

  • But in a way you also lose informations as you reduce the position to a single point from the Schrödinger equation ... So don't that makes order ? + it cost energy so it would make sense to create order for energy, no ? That might also be why quantum stuff happen, since you're small and low on energy you just become so anthropic that you become to act as wave to get maximum information from less energy and also why we aren't able to make big chunk of matter into some intricated state for instance in quantum computering ?

  • Ben Franklin wrote “I am for doing good to the poor, but...I think the best way of doing good to the poor, is not making them easy in poverty, but leading or driving them out of it. I observed...that the more public provisions were made for the poor, the less they provided for themselves, and of course became poorer. And, on the contrary, the less was done for them, the more they did for themselves, and became richer.” We don't owe poor people anything because if we gave to some people without cause they would expect to be given when they gave nothing in return to the cause. It has to be an even scale of give and take and give some more. Socialism does not work simply because the public feeds the public and nothing is ever returned Look at Canada's healthcare system it's complete garbage where some people are just waiting years for their Socialist health care cards. You can't do that type of thing to people. There are always those who would take for granted that they got something for free and be back next week to collect their stiphons without contributing to the cause. Ben Franklin knew this.

  • Nice chest bro 👌💪
