Direct link to cgepfert's post “Quantum Physics can be us...” Quantum Physics can be used synonimically to Quantum Mechanics and even Quantum Theory. Quantum Physics is theory which try to explain why Classical Mechanics doesn't work in cases for example very small particles or also explains some "more visible" phenomenon like superconducting. There is the series of videos in Khan Academy, so if you are interested you can learn from them a lot :) (78 votes) Moona Javed 6 years agoPosted 6 years ago.

If the reaction force is same for both cases, why dont i get hurt in both cases the same way? • (17 votes) The #1 Pokemon Proponent 6 years agoPosted 6 years ago.

Direct link to gccostello4's post “NGSS is a program of newe...” NGSS is a program of newer education. They have more concise lessons, and they have cut out certain information that might not be needed as much. The best way to know if you should use it is (1) what state you are in and (2) what you're using the course for. NGSS has only been implemented in the following states' education: Arkansas, California, Connecticut, Delaware, Hawaii, Illinois, Iowa, Kansas, Kentucky, Maine, Maryland, Michigan, Nevada, New Hampshire, New Jersey, New Mexico, Oregon, Rhode Island, Vermont, and Washington, which is 20 out of the fifty states in the US. If you live in a state not listed (like mine, I live in Texas), then your state does not use it in their curriculum. If you are taking the course on your own and not taking a credit by exam or taking it for your school or university, then you can choose whichever you prefer. If you are taking it for school, then I would recommend using whichever one is used according to your state/country. (I'm not sure if Khan Academy teaches for out of the US or not) (4 votes) Benjamin.X.Wu 4 years agoPosted 4 years ago.

Because according to Stephen Hawking universe originates in white holes and ends in black holes.
So the laws of universe may not apply there.
