Excuse me, professor. The expression you put up on the board at around 4:50 is not necessarily correct for any given field. How does this affect the theorem itself? I mean, the only counter-example I know is a field in a non-simply connected region, but the question is still up.

@jasondonev7038 3 ай бұрын

Non-simply connected regions aren't within the set of fields that we're talking about in this series (we're focusing on fields that are useful for E&M, but the statements are broader than that). I don't know much about fields that aren't simply connected, so I can't meaningfully speak to them. I'm uncertain if they vanish at infinity in the way that's necessary for Hemholtz's theorem to hold.

@murillogregorio1533 3 ай бұрын

Yeah, I stopped to think a little about it, but didn't came to any concrete conclusion. The only example of field in non-simply connected region is that of F(x,y) = -y \hat{x} / (x²+y²) + x \hat{y} / (x²+y²). See that it does vanish at infinity, but the singularity at the origin makes it not-conservative in general, although its rotational is indeed zero.

Bonjour , merci pour la vidéo. Vers 3:40 vous dites "ainsi toutes les matières fissiles ne sont pas fissibles, mais toutes les matières fissibles ne sont pas fissiles". Je pense que vous vouliez dire que "toute matière fissile est fissible, mais toute matière fissible n'est pas forcément fissile" (puisque pour les matière fissibles un neutron lent ne peut pas déclencher la fission de l'atome, il faut en effet nécessairement un neutron rapide pour initier la fission).

When they in the 1950s talked about "too cheap to meter", they were talking about this. Our failure to better utilize nuclear has been extremely disappointing, but we *will* get our act together, because we *must*. We simply cannot ignore basic physics forever...

@@energyeducation4087 Gasoline is 13% hydrogen, so hydrogen actually has 7.69231 (1 ÷ 13%) times more energy than gasoline. Hydrogen is 120 megajoules per kilogram, gasoline is only 15.6 megajoules per kilogram.

I have a question. I got a therapy using radioactive iodine, I have to be isolated for 8 days and I've read that its half life is about 8 days. Does it mean that in 8 days the radiation has decreased by half? Sorry, I really don't know haha I'm just curious about this

The fuels you compare to uranium come out of the ground or grow with relatively little processing. The fuel density should include the weight of all the waste produced...then the equation would be a little more balanced.

@energyeducation4087 2 жыл бұрын

Including the waste produced from the different energy sources would make this even more starkly in favour of nuclear. The waste from coal (for example) triples in mass when burned and gets 100x times larger. The waste from fossil fuels is causing widespread devastation that are a threat to civilization, as opposed to the waste from nuclear power which is comparatively easy to handle. The energy density described in this video is a big part of why nuclear power's waste is fairly easy to handle.
