Quantum Mechanics

http://www.myspace.com/acorvettes The Danish physicist Niels Bohr, who worked in Rutherford's lab, was the first to describe orbits of fixed size and energy in which electrons are free to travel without losing energy and falling toward the nucleus. According to this model, published in 1913, electrons can only occupy or jump between fixed energy levels and cannot reside in between these levels. In addition, once in their "ground state," electrons maintain the energy they contain. This energy keeps them in perpetual motion, allowing them to resist the attractive force of the nucleus.

beautiful

what made Bohr think of and assumed the presence of well defined electron orbits around the nucleus which allowed further acceptance of the atom concept then? was this simply fudging to make things seemingly fit preconcieved ideas or was this derived from some verifiable mathematical computations-was this just a thought experiment that was serependitious? thanks.

This is beautful

So when we die do we die forever and nothing more?

Can anyone tell me what video this clip is from?

But that's all it is...just a probability...not an exact point in space and time. One physicist(forgot the dudes name sry) once said "You can compare looking at an electron to looking at a cat. There is a probability that the electron is in that point in space or not in it, similar to the probability that the cat you are looking at is dead or alive."

from my understnding ...the 'probability of finding this point particle ' IS through the wave...but why did he not say 'wave function'?isn't he supposed to say 'wave function'?

darkknightgaury (Monday 10th of November 2008 09:52:23 PM)

No. You can measure the position of the electron. You can use the bohr model for hydrogen like atoms. But you need the wave function in order to calculate what is the probability of an electron being in some space.

Well, certainly you may think so but it is still strange how an electron can be in two places at the same time. This phenomena has been observed, it is not about the position of an electron it is about the nature of the electron itself...Wave particle Duality.

We have technology to measure the position with great accuracy :D
