The Chemistry Behind The Forming of Different Colors of M42 Nebula


PS:IT’S NOT A RESEARCH PAPER Abstract This paper begins with the Messier 42 nebula, talking about how different color lights form due to the electron transport in Bohr’s model. How these lights are absorbed by gas and form the absorption spectrum, then how these lights are captured by sensors with the explanation between CCD and CMOS sensors. The history of spectrometer also includes plus...

How I understand the Ideal Gas Law


After learning the Gas law, that I got some general idea of the beauty of equations, I think the expression of textbooks is pretty strange, they trying to divide one simple formula to several different unclear ones, hmm… I think the better the equation is the more factors it includes in; it does not let the question become complicated but even make it even simpler because people do not need...
