My understanding of clear materials is that they allow all lower photon energies to pass through due to the energy gap.
This makes sense for UV proof glass, it blocks higher energy photons.
What I dont understand is how a material can only let a certain range of photons through, like most of the visible range but no infrared, because that means its blocking a lower energy level and allowing a higher energy level which doesnt make sense to me if the energy gap between electrons is what causes transparency.

How do you study, /sci/? I, 1.Write all of the definitions in a chapter. 2.Write a checklist of what I'm going to do that study session 3.Skim the chapter quickly and then try to condense it into three or four pages. 4.Finally, once I think I know the material well enough, I do the questions in the book and some exam questions.
Is there anything you do that you think is better than that?
There's that familiar feeling again. When the present state of research can't satisfactorily answer the most base of questions, and every scrap of literature you read contradicts another. Then you get the reviews that read like opinion pieces.
I just read a whole review, complete with a few hundred citations, that was essentially trying to say the only pharmacologically relevant components of cacao seeds were flavan-3-ols, methylxanthines (mainly theobromine), magnesium, and some other antioxidants. The rest of it was a snotty half minded display of trying to... Comment too long. Click here to view the full text.
This is one of many things that is beginning to really piss me off. I can't stand disjointed garbage that doesn't fit together, and I hate even worse stupid shit making its way into the available body of literature. It's one thing to try to substantially dispel myths and try to make it clear a good direction for further endeavor it's another thing to say idiotic shit that doesn't agree with experiment or empirical observation. Maybe this moron should have spent some time eating enough chocolate to get high on (not as much as you might think), rather... Comment too long. Click here to view the full text.
>>7770026 Go get either some high quality dark(er) chocolate. Make sure it contains both the butter (fats), and the solids. Sometimes this will be listed as "chocolate liquor", which just means a roughly 50/50 proportion of cocoa butter and solids. Make sure it's not processed with anything (dutch process, roasting, alkali, etc. This is done to reduce pH and control bitterness).
You can either do this in the form of cacao nibs, chocolate chips, or chocolate bars. Chocolate chips is probably the most viable,... Comment too long. Click here to view the full text.
>Did you follow your dream in your choice of study?
Yes, Pure Mathematics.
>How is it going now?
Just in freshman year and I already got a paid internship working in banking software. I start monday.
Man, being a mathematician is like living life in easy mode. Literally everyone wants to hire you. You got software on one side, statistics on the other, finance on another, research everywhere and rich people want you to tutor... Comment too long. Click here to view the full text.
>>7769871 I picked mathematics because it's very little work
Couple of homework problems each week is at most all they grade, the rest is just exams No papers, no projects, no groupwork. All you have to do is study an hour or so a day (at most) to keep up and that's not too hard because I enjoy mathematics anyway.
Is buteyko a legit method for everyday breathing?It seems like it does wonders but i never seen it discussed.It would be great if some anon can take a few minutes of his time to read the info on this site.
>>7769617 intuitively: the wavelength of a light wave is the distance between the "peaks" of the wave, right?
If study a beam of light that comes from the left towards the right with a wavelength [math]\lambda[/math], and you move to the right with speed [math]v>0[/math], do you agree to say that you will meet more peaks than me? (since you are catching up to them).
Notice that if light moves at the speed of light, it doesn't mean that the peaks themselves move or move at the speed of light.
