Write a response to this " The topic that I chose is quantum physics, and the video that I watched was about light and quantum physics. The video was on physicists in the 1920's Einstein, Bohr, Heisenberg, and Schrodinger, and how they debated on how electrons move around an atom. One concept I learned was that to observe the electrons; you can use light: a weak light slows them down so they can be seen but can not tell where they are, and by using a strong light, they move very fast, but you can see where they are but can not measure the movement of them and with only being able to see one or the other leads to the second concept that I learned which is where Schrodinger's cat came from, I had heard of it just did not know what it pertained to, if a cat is in a box there is no way of knowing if the cat is alive or dead without looking in the box and with electrons if you can only see one aspect at a time, there is no way of knowing what the other aspect is doing
