I am somehow running for the board of #EOS. If you think that having me there trying to expose more people to the beauty of optics is a good idea, you might vote for me.
On the other hand there are a lot of excellent candidates on the list, so you should probably vote for one of them ๐Ÿ™‚

Usually because the second method is easier and shorter only after you built enough intuition with the first method.

4-panel SMBC comic update. A woman is teaching a man sitting at a desk. The man says "I get it! You write (equation)* and that tells you the superposition is some amount in the 0 direction and some amount in the 1 direction." The woman replies "now that you've got it, we'll use this easier form" and proceeds to write a much longer equation on the board. The man then says "this is why people become chemists" to which the teacher replies "do not use the c-word in my presence"

*equation won't copy properly in the alt-text.

I find telling that all the interviewed people were super happy about their degrees, meaning all the academics did their job properly.

Due to its yellowness, a friend of mine dubbed him "Orconzola", so this is now his name forever.

Nonlinear harmonic generation would require fs pulses. These IR cards are phosphorescent (and thus very broadband).

I am old enough to remember these games from when they came out, and looking back at them it is i interesting that nobody commented on their controls. Because nobody knew any alternative was possible.

One more finished model, a million new things I tried for the first time. The most notable were blending contrast paints, and the crackling on the base.
Biggest mistake was not to undershade enough before applying the contrast paints.

This is the original sin of higher education.

(So many) students see University as a away to access better paid jobs.
Universities see students as income.
(So many) professors see teaching as the price they have to pay to be allowed to do research.

Learning is almost never discussed.

As everybody knows, nobody from those countries can be a good student, worth of a place at Uni. Therefore it is entirely reasonable to deny them study visas.
