I'm becoming obsessed with cuttlefish.

They are intelligent, reproduce in large brood sizes, have short lifespans with short generational gaps. Their color based communication language is fascinating.

In other words they are the perfect organism to apply artificial selection to. We could breed an ultra-intelligent cuttlefish in no time.

Am I crazy /sci/?

not at all crazy. but artificial selection is fuckin stupid. It poses several threats if accidents were to occur, costs tons of money, trial and error very time consuming.

It would be more viable to colonize the South Pole of Earth, but no one is going to do that because it's stupid. Surface structures like greenhouses are fantasy.

If you rolled N, the odds of you getting a bigger number is pretty much

(100 - N)/(100)

So solve for

(100 - N)/(100) > 0.5
100 - N > 50
-N > -50
N < 50

pretty easy.
>>
of course it's 0.5

I've seen so many youtube videos but it's mostly just proposed experiments for a gyroscopic anti-gravity device?

So is there any magnetic/anti-gravity/fuelless propulsion system or is it all just a meme?

What note taking strategies do you have?

My main question for math is, should you have homework and notes in the same notebook?
20 posts and 2 images submitted.
>>
>>8698399
I keep notes and personal exercises in the notebook. Everything homework or generally assignment related I do on a whiteboard then LaTeX it up when done.
>>
I sorely need tips on keeping up with the lecturer and making notes that are 1) useful; 2) legible; and 3) malleable.

I'm terrible at making lists, determining whether the lecturer is switching topics, and generally organizing my notes. I've tried Cornell. It just comes out as a dense mess without any sort of system, either in using shorthand symbols or in using available space.

It doesn't help that my handwriting is garbage and that I often need to rewrite what I've written because I'll write some garbage sentences in-the-moment to summarize the information because I can't quite think of a better way to phrase it. It's gotten to the point where I don't take notes anymore because I don't even bother.
>>
One notebook per course for lecture notes. I write with a colour other than blue and later go through the material and add notes in blue ballpen if anything is unclear.

I use seperate notebooks for exercises and loose thoughts.

>>8698538
Try to structure your notes into definitions, lemmas, theorems and remarks. If you look out for these things during lectures you should be able to avoid trying to write everything the lecturer says down.

How would you know you don't even have a nose or eyelashes
>>
>>8695803
Because eyelashes can get pulled out more easily dumb ass
>>
>>8695803
early humans would often get into fights with wooly mammoths in the savannah. one of the mammoths' favorite tactics was to pull the humans' eyelashes to distract them; hence, humans evolved so that they didn't feel any pain when their eyelashes were pulled out. don't know about the nose hairs.

spaceship is flying through space
for the crew to be at constant 15-20G force
they would need to be constantly accelerating
right?
not just - we are going fast
but - we are going many times faster than 1 min ago and increasing

just asking cuz i saw latest episode of scific series the expanse, for 15G the crew needed some special chemicals to help survive
