  24. Despite the fact that the thought experiment allows for no resistance in the wire... Veritasium is making several mistakes. The amount of energy required to light the bulb must be considered as "some reasonable" amount of current for the Light to turn on, NOT "any ridiculously small amount of current". The claim is that the when the switch is closed, the current starts moving which induces an electromagnetic field (EM field) in the wire near the switch. This means that an Electromagnetic Wave will be produced and start radiating from the wire and will reach the light bulb after traveling only 1 meter. However, Veritasium ignores the fact that the EM Field traveling thru the air or free space will be inversely proportionate to the square of the distance. Therefore the energy reaching the bulb after 1 meter of travel in the air, will be very very small. The counter claim would be that the amount of current needed to turn the light bulb on is very very small, and any amount of current would turn the light bulb on, but then why bother with wires at all? It makes no sense since in that case, one simply has to touch the battery or touch a switch connected to the battery, and not even have the wires present. So it makes no sense to setup a giant thought experiment requiring 300,000km of wire with a switch if all Veritasium wanted to demonstrate was that EM fields radiate. So, we must conclude that Veritasium earnestly believes that the energy in the EM field traveling thru 1 meter in the air is enough to power a regular light bulb with regular amounts of current. But he is wrong. Some will say that Veritasium requires "ANY" amount of current to be acceptable. But the counter to that is ... no. He claims that once current reaches the bulb then the bulb instantly turns on. That current must be considered as "the required current" to activate the bulb and not "any" current... otherwise, mere movement of anyone to even turn the switch... the blood flowing in your body, etc would activate the bulb thru induction. so since that is a preposterous assumption that such a low amount of current would activate the bulb we must then conclude that the bulb does require a standard amount of current to turn it on and simply that it must turn on immediately when receiving that current rather than a delayed effect in time due to filament heating / driver charging etc. I also find it immensely frustrating that the "papers" provided by the experts are in no way "proving" any of Veritasium's claims. They are not 1 for 1 and they are extrapolating two or more very different experiments. Additionally, they are simulations and then those simulations are extrapolated. Going back over the Power point provided by Veritasium shows that at 2.5 seconds only 0.25 volts are measured (under the simulation). That is FAR LESS than the energy needed to light a bulb. Extrapolating to a 12volt car battery and light bulb we get ~1/10th of a 12 volt battery's voltage which simply cannot light a bulb. So the answer is that current necessary to light the bulb properly must travel 300,000km down the wire in order for the bulb to receive enough current to turn it on. So the amount of time to travel that distance is the amount of time it will take for the bulb to see that current. Additionally, it is not constructive to claim that we have been told "Lies" about the nature of the electrical energy. Those are theories. Not lies. It does science a Great Disservice to rebrand past theory as "lies". @Dr Ben Miles... I agree with you on almost every point. @Veritasium, with respect, It devalues your integrity to use these methods to drive conversation. I much prefer your older more conscientious methodology where you are more careful about the things you say. I am especially focusing here on the claim regarding "Lies" in your video. Remember that your value to the scientific community is in your integrity not in your hype.

  31. Good video, glad to see someone tackling exactly why this sort of TV 'endorsement' by proxy is so damaging. As someone with ME I'd just like to add that our primary symptom is not actually fatigue, it is post Exertional Malaise - which is a giant flare up of all our symptoms including feeling flu like and very unwell indeed, caused by going even slightly over our physical limitations, anything that uses energy counts - including talking, reading, and even THINKING for people at the very severe end! Thinking uses energy on a cellular level - how else would it happen after all. I would appreciate it if more people could start making sure they mention Post Exertional Malaise since it really is the symptom that rules them all, so to speak. It is what rules my entire life and it's risky - trigger it often enough or big enough, and you don't really recover back to where you were, you stay stuck at a lower level of functioning, it literally makes you sicker than you were. Over time some people end up dead, because it's so incredibly difficult to control and keep inside your limits. When 'over doing it' can simply mean you had an upset tummy and went to the loo a few times too many that day, or had to pick something up from the floor, or simply moved around in bed a bit too much that day, it is unbelievably difficult to stay inside your limits and prevent triggering PEM, many people don't manage it and therefore deteriorate over the years getting sicker and sicker. It's so poorly understood by medical staff that going to hospital becomes something to fear. Research is coming along though and I love that this video talks about how we need more people investing in genuine medical entrepreneurship, moving real, science evidence backed treatment forwards. In all areas, but hopefully soon for ME too.
