i can't hear the voice clearly so i suggest to add english subs down in medium sized clear font.thanks for video.but would like to know about the school,place,department.if possible load all your lectures of all subjects so that we can study.plz reply soon.

inner electron orbits can be exactly calculated by elliptic functions (see Klaus Huber Cauer Filters) - it also supports more exact calculation for satellite obits

And your last question....

It depends on the exact amount annihilated but if by annihilated you mean matter/antimatter explosions it would either cause drastic seismic activity to complete destruction of the planet

Next one....

One thing to remember about photons is that sometimes they wanna be a particle, sometimes they wanna be wave. Thats beside's the point though. Photons hit the top of the atmosphere as well as they ground, what matters is the wavelength of the photon, some wavelengths get filtered out, some wavelengths pass freely through until they hit the ground. This is also how life is possible on this planet and how greenhouse gasses work.

Therefore, if an electron were to get into the nucleus of an atom, it's momentum would increase as it's position became less speculative. An electron does not enter the nucleus because quantum mechanics says no.....

@GateMessenger

just came a long to this video and this comment might be a bit late, but i'll attempt to answer your question. In quantum mechanics there is a little, er, principle called the heisenburg uncertainty principle which states that the more precisely you know one physical property of a particle the less precisely you know the other property. In other words, if you know the position of an electron more precisely, the less you know it's momentum.

Our universe is a really weird place. It makes no sense to my ape brain, but it works.

You can prove with Maxwell's equations that accelerating charges must give off radiation, and radiation contains energy. Therefore, accelerating charges must emit energy. When dealing with lumps of charge, this dragging effect can be understood in terms of the front of the charged lump acting on the back of the charged lump. When dealing with point charges on the other hand it is harder to explain where the retarding force comes from. I don't think that a completely satisfactory answer exists.

Because they carry a charge. Planets are electrically neutral. As simple as that : ).

@prepstarr25 where do you get that idea from?
