>introduction to proof

>>7656887
what's so funny you bumfucker

>>7657434
Not to comment on the contents of a book I've never read, but you should have been introduced to proof at the high school level, not at the upper division level.

>>7655860
yep. bacteria are just gonna grow. idiot.

>>7655860
the fact that the eggs are full of nutritious/delicious proteins is exactly why the antibacterials are there in the first place - to fend off hungry parasprites. this experiment can show the effectiveness of these lysozymes in their egg drop soup served on paper plates, but if you want to find their effectiveness in other environments... well, you know.

>>7655860
Don't see a problem with that. Even bacterial growth would be a result, just like the opposite (antibacterial effect).

The processes behind reviving someone in such a way are still far from reality and the methods that we go to cryogenically freeze shit today are not good for tissue to begin with.

We have no use for cryogenically freezing people and reviving them to begin with. The only realistic application is long term space travel or some shit like that and we're better off trying to get shit like the meme engine working.

So the only people left outside of that who would give a remote shit about that specific application in cryogenics is the industry of rich assholes who want to be frozen before they die of cancer so they can come out 200+ years to get "cured" and I assure you nobody working in that "field" gives a remote shit about successfully reviving someone from long term cryogenic storage.

You're basically better off waiting for long term changes in medicine and science that allow much longer lifespans with in turn result in a better chance of you being around for further semi-immortality.

I believe, Anon.

If it truly was a giant waste of money the government would be doing it by now.

Because you're pushing the limits of what humanity can do. You're thinking about abstract concepts and forcing your body to answer questions more complex than. How to avoid bear? How to get food? How to fuck her? etc. The latter is your natural desire.

Sometimes brilliant people break down and just retreat to the wilderness as primitives because they crack.

>>7659694
I doubt it's something you'll have to worry about.

>>7659711
I don't claim to be super intelligent or anything, I'm still above the average person in terms of problem solving skills however, granted that's probably a part of the whole autism thing

Apparently according to new research autism was a trait that was useful in hunter gatherer tribes where there was less social interaction to be had and the enhanced reasoning skills it tends to give let it survive though generations, or something like that

>>7657498
>why not
Exactly.

>>7657498
>would you work for a defense contractor?

Yep

>Why?

Because humans have been killing each other since time immemorial, if I didn't work that job someone else would and if no one worked that job then we'd just go back to killing each other with large bits of rock and pointy sticks.

>>7657498
Yes

The human race being just as shit as it always was in new ways, and maybe new places.

It'd be good for the universe if we never managed to leave Earth. We're going to spread like a disease.

>>7656863
Three primary possibilities:

1.Humans remain on earth. Humans continue being humans. Theres pain, war, struggle, despite some things being improved. Everyone keeps on getting by, particularly poor places get richer, etc.

2. Humans leave earth. Basically precisely above except we also have people on other planets. Cool!

3.Industrial society collapses and we go back to preindustrial living. Humans continue being humans just as they did for thousands of years.

stop.

Not evil, intrinsically broken. We aren't able to be or create anything we don't hate on some level. This is potentiated by existing in a group.

I love watching them freeze up and error while considering that I'm expecting them to remember everything they learned in precise detail. The smart ones start panicking and reviewing, the rest just get depressed.

>>7656787
>Hand wave hard proofs, go through easy proofs with infuriating detail.

Guilty as charged :^)

>>7654887
What on this green earth is happening in your pic?

are they convex? Then use separating axis theorem. If you are trying to make your own collision detection system, just use bullet.

>>7654894
for all shapes

I'm looking for a general solution

>>7654910
You can't detect collision for real, any-shape because you can't represent it in computer memory. You need to simplify it first.
Do you want shape based on triangles or voxels or mathematical perfect primitive shapes like spheres or cylinders? 2D or 3D or higher dimensions?

I've TA'ed calculus and a bunch of people failed if that counts. Derivatives are some wack shit, but I think what holds most people back is the algebra rather than the concepts and the formulas.

>>7653079
This to be honest family, more so when integrating, algebraing the fuck out of functions to fit the formulas is the hard part, mostly because relies on mathematical intuition and algebraic experience more than actual knowledge of what your Calculus book says.

>>7653072
>Derivatives some wack shit man
You better get the fuck out of here with that weak shit.

Deriviatives are literally the easiest part of calculus. The operators take two seconds to complete, and the chain rule is only mildly complex.

Calculus is the shit son. You better read the Principia and realize how much of an ingrate you are.

Why women?

At least STEAM rhymes with meme.

>>7652676
>synchronise their clocks

whooops

>>7652676
Think about this.

How do they synchronize their clocks?

What is the physical method of determining synchronisity?

>>7652676
those names seem familiar

I don't understand what you're saying.

Calculators take a taylor series approximation that's good enough for anything.

>>7650963
[math]tan(x)=sin(x)/cos(x)[/math]
[math]cos(x)=sin(x)*tan(x)[/math]

:^)

>>7650411
Because if we had no attraction we wouldn't really care about reproducing. Attraction brings competitiveness which brings survival of the fittest.

>>7650545
>Why are women attractive?
Scent, associative factors, and tendencies of the brain when processing shapes and conceptualizing. Why does some food taste good and others not? It's of the same basis.

The only odd part is how these mate selection heuristics come into play to begin with. Some of it can be explained, others are a bit harder. Like choosing women that aren't just genetically fit, but have behaviors suggesting they'll be viable partners to work with and raise children properly. That might be spillover from other desires and tendencies.

>>7650545

better question, why are some women NOT attractive.
