This is how you convert AC to DC. Diodes only allow current to pass through one way, so no matter how your input current direction varies, it will ALWAYS direct current to your output in the same direction.

MIND. BLOWN. Science is so cool. People are so brilliant. Technology is so advanced. The things we learn about in class are so effing amazing. Half of the time, the bigger implications of what I’m learning go over my head. But it’s little snippets like this that make my day. I wish I were smart enough to have my mind blown more. But I’ll settle with what I’ve got.

EDIT: Friend pointed out you also need a capacitor attached across the voltage to stabilize the current, so it’s actually a straight line as opposed to an absolute value version of a sine wave.

RANDOM SCIENCE FACT 2: if you twist a piece of chalk, it will break in a helical pattern, at around 45 degrees. This is because chalk tends to fail in shear, and shear stresses are greatest at around 45 degrees.

consequences

Man. So I accidentally deleted most of the pictures I shot this weekend, due to not really understanding how to work the RAW editing program that I finally figured out how to use.

Including a picture I took of a worker at a carnival that I went to. She asked to see the picture, was really happy with how it turned out, and gave me her email address so she could send the picture to her mom. It was a big moment for me, realizing that my pictures go a bit beyond personal satisfaction, and can touch other lives as well. Realizing that while I have a lot of room for improvement, what I’ve got right now is enough to make some sort of impact.

Not sure if I should email her explaining what happened, or just never email her and hope that she totally forgot because she probably has a zillion other things on her mind.

I’ve tried recovery programs on my SD card, but omehow it recovered all the cookies from my internet browsing, because all I see are memes I opened (but never saved) from browsing Reddit. I don’t think .ARW files recover as well as JPGS. :(

Sometimes I don’t give a crap that I’m irresponsible and rash. I can mess around with system files and command prompt without a care in the world. I’ve only reinstalled Ubuntu like, 10 times at this point (12.04 comes out in less then a week! Reinstall again!). I can throw together meals with limited/strange ingredients like no other. I’ve only made myself sick a few times. I can always get another cool long-exposure shot of a spinning ferris wheel, never mind the fact that every shot I took was different because of the endless patterns that the ferris wheel lights up. Whatever right? There’s always tomorrow.

But you can’t replace a memory, and so maybe I’m thinking I should start giving a crap to the way I treat things after all.

On the bright side, shooting in RAW will no longer be as painful and terrifying as it was before. That is actually a pretty big deal. Darktable, you were a challenge, but I have finally conquered you in your unnecessarily complex multi-functional glory.

Beautiful beautiful thing.

Always reblog Proust. I think it’s Proust.
