    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

    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 😅😅😅

    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.

    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.

    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.

    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.

    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.

    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

    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.

    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.
