The 6 points of advice I have given to many people in my life are pretty much what I distilled from baz Luhrman's speech (my last post). This is basically the advice that has stuck with me from that:

1) Do one thing every day that scares you
2) Don't be reckless with other people's hearts; don't put up with people who are reckless with yours
3) Sing every chance you get
4) Never let distance be a barrier, travel!
5) Never expect anyone or anything to financially support you
6) Be critical of advice you receive, but be patient and kind to those who give it.

# Fluency in math

Fluency in language is relatively easy to measure: you can give a talk, keep up in a coversation and write jarry, more or less gramatically coherent texts. Math is trickier: most people struggle with it, some people seem to be better at it naturally. I have no idea why is that the case, but there is an interesting observation.

Math is language we describe universe with, because words aren't suited well for this purpose. There are a few major concepts that are tough to describe in plain language, like limits in calculus and tensors in algebra. And math is a weird language, mistakes are punished way more than ever, infact, one wrong symbol renders the entire "text" meaningless. This breeds frustration.

Fluency in math, in a particular parts of it, consists of two things. Firstly, the ability to derive new relations and transform existing ones effortlessly and without mistakes. No, there is no "I know this, I'm just so inattentive" when you skipped a minus sign. Mistakes show gaps in either knowledge or skill, they are a signal for you to get some more practice.

Secondly, the internalization of concepts. It boils down to the Feynman rule: you only understand it if you can explain it. The only way to internalize a concept is to link it to existing knowledge: think of the knowledge as a map, and your competence grows in a tree-like shape all over it, creating nodes and lines. As long as there are enough nodes near something new, you can learn it. If you struggle - roll back and explore the area around, maybe go slightly sideways or practice what you already know.

Guess who got another old camera converted to infrared and can now do 700 AND 550nm? Damn, that red leaf effect is powerful, even if a bit tricky to optimize in post-editing... #infrared #photography

The meaning of life is 42. The ascii code 42 is “*”, which is a wildcard in regex. Thus, the meaning of life is whatever you want it to be :)

Palestina se levanta, Palestina resiste, Palestina es un ejemplo de resistencia elevado a la enésima potencia. #palestinalibre

This is about my perspective as well. Israel has often spoken about not having a partner for peace, but do the Palestinians?

#TIL When a Class 2 ceramic capacitor is heated above its Curie temperature (130 °C), the crystal structure changes. Soldering the cap causes a sudden increase of capacitance beyond spec (so don't attempt to hand-matching ceramic caps!), followed by a logarithmic decline (aging). This is reversible, resoldering the cap or baking the board can "reset" an aged cap back to the initial state.

"Referee time" is the time for a cap's capacitance to decline back to its standard spec value (X7R cap ages slowly, referee time is 1,000 h., X5R is only 48 h.). A DC bias not just reduces the effective capacitance, but further accelerates aging in a nonlinear way.

As usual, Class 1 NP0/C0G capacitors are not affected by these effects. #electronics

@jhagas The world would have to scream in pain at this, but all you hear is silence.😢😢
