!Organic chemistry reaction I just wonder is there any ways to predict the catalyst and other conditions for a certain organic reaction to happen?

oh yes..that makes perfect sense now..thank you so much

I don't know if this question is stupid, but i am curious Since the nanobots are so small, will they follow or getting affect by the rules of quantum physics?

I red something about Nano-Desulferizer, the article said something about how people can send Nanobots that carry calcium and magnesium to the atmosphere and react with SO2 to produce salts, which prevent the acid rain.. I wonder why Nanobots, why they can not just send something else that...

Thank YOu Jesse M, i think I get it now. but..ah..I am not sure how do you know which one is suppose to be the proper length. In this scenario, is it true that the captain finds the distance separating the two events to be Lm is because of she thinks the planets are moving, and she is...

haha thank you for helping me It is Thomson Nelson Physics 12. By Hirsch, Martindale, Sewart and Barry It is in page 574

Yeah..My textbook use the time dilation relationship to derive the length contraction formula. They mutiply both sides by v, which is the speed of the spaceship.. then V*Ts becomes Lv, and V*Tv becomes Ls

Thank you JesseM "Probably the first means that in the rest frame of the spaceship, the distance from planet A to planet B is less than it is in the planet's own rest frame, and likewise the second would mean that in the rest frame of the planets, the length of the spaceship would be less than...

Thanks to Diazona and Feynman respond to my question Ls is the proper length, and Ts is the proper time now, I think I understand the formula.. however, i still don't really get one concept.. My textbook says, when you look at the length of the spaceship as proper length, then the distance...

Hello, everyone I am learning special relativity in high school.. I understand the time dilation thing...but i have trouble to understand the length contration.. I am getting confused why Lm=ts*V and Ls=tm*V Please help..thank you

Thank you fatra2 for reply my question. looking forward to see more explanations.

Hello everyone, This is not a typical homework question. I found this confuses me when my teacher derives the special relativity formula in the class. Here is the derivation: 1. The astronaut, stationary relative to the clock incorporated in the bottom mirror, measures a time interval 2...
