Here is the average amount of trash piling per month in one mid-sized district. multiply this with about 300-500 for the monthly trash of just one city. Now add transportation costs to carry all these to the nearest volcano.

Also, volcanos do not disintegrate trash into the atoms and erase them out of existence. They produce leave a liquid black unburnable residude and toxic fumes by burning plastic and all other synthetic material, which spreads into the air we breathe. Doing this every month is highly pointless and expensive.

Because you want the radioactive waste to be in a location with stable geology, not one that is liable to spew radioactive gases into the atmosphere at the drop of a dime.

Find your class. Watch the vids at your own pace. The professors at MIT are light years ahead of your shitty dead end associate professor.

Read the book, teach yourself.

you have to believe firmly that most of your profs are not there because they're good teachers, lecturers, educators, people...they generate money and publicity for your school. when i was in uni i would go to class for a week or two and see if i vibed with the prof, then skip class the rest of the quarter and teach myself the material.

why are there so many fucking FTL threads on this board?

because they just recently found a way to travel faster than the speed of light, read the news

none of them lol! Causality, relativity, FTL, pick two.

Yes.

Any one body without a handle is topologically the same. Pic related is the Wikipedia pic for one body with one handle (demonstrating homotopy transformations)

>>7653054
It sounds like you have a problem visualising the gluing process. Just see what happens as you pull the sides into the two corners while keeping the boundary connected. I think wikipedia has a gif of the process of making a disk into a sphere, probably on the quotient space page.

topology is the shit tho

just because you don't understand it doesn't mean it doesn't make sense.

We just don't know


yet.

Because without something there can be no nothing. Without an ever there can be no never, nor forever.

The very logic you're using itself is based on existence. Non-existence probably isn't meaningful in the same way, as it's a consequence of the existing framework of logic you have available.

>>7652922
In the set of all possible complete mathematical representations of the universe, there is only one way in which nothing can exist, the empty set. There are however, one assumes, an infinite number of ways things can exist. So, it is infinitely likely things will exist, and infinitely unlikely nothing will exist.

It's much better than grape juice, which is basically just sugar water, but probably worse than grapes.

However, it also lasts much much longer than grapes do because alcohol is a preservative.

All told, red wine is good for you in moderation.

>>7652888
>is wine superior to grapes and grape juice from a health pov?
No. Any benefit of wine can easily be found in myriad other sources.

>>7652897
please give some examples, still it would be not bad if you could drink wine too

>>7652894
I mean grape juice made from grapes, not bought from the grocery store. Somewhere I read fermentation adds valuable nutrients to the mix.

I independently derived the fact that the "new thread" function is a projection from the space of 4chan users onto the space of faggots

When I was in kindergarten I figured out 10X10=100 when I barely knew what multiplication was. All the other babbies were impressed :^)

>>7652828
I guess this was pretty lame, but back when I was in physics 2, I was working through the derivation of the RC time constant, and thought the method used for analyzing the circuit was pretty cool.

So I went to a math instructor and said "Hey, this is pretty cool, given just a relationship between a function and its derivative, you can determine the function! Is there a way to generalize this, it seems really useful."

He told me "Yeah, it's called Differential equations..."

psychology would be almost as useful as astrology, except that gravitational waves produced by stellar objects is real and any purported objective description of what goes on inside your head that doesn't take into account external factors is not

>>7652810
Psychopaths are supposed to be more organized and harder to spot. Also they tend to be born with it as opposed to being a victim of child abuse or something.

ethics, and the fact that doing it in mice doesnt mean they have figured it out, or even can, do it in humans.

>>7652694
What exactly are the dangers of doing this to humans?

>>7652702
Pick a bad genetic mutation...any of em. That's the risk you run.

>>7652621
Also opinion on the ethics of passing such genetics on if I have a daughter since male wouldn't inherit.

>>7652621
Having a daughter would be more ethical than having a son with these mutations. While the COMT muts would only affect a female its probably the case that the mother would have non mutated genes that would compensate for the mutations present. Also 23andme only does extremely basic shit so the data is most likely reliable. Also males would inherit. Look up x linked diseases in males. All of these genes (except the last, I didn't. check that one) are x linked

>>7652621
Also, you wouldn't want the info released. One of the guys who worked on the human genome project switched a sample containing donor DNA with his own and got caught when geneticists were using basic tools (I think ncbi) to look at some of his genes

either could allow you to work with robots, but i recommend the mechanical engineering approach as it tells you everything you need/ want to know about robots, and then some

Why do people always want robots to look humanoid??? Unless its for sex, there is literally no reason to spending time on how to design such a thing. A robot with a simple form cna perform most tasks just as good if not better than one with a humanoid form.

>>7652620
>Not the ones in factories that build cars together for example, but humanoid robots.

good fucking luck. every engineer out of college wants to do that. 99% of everyone that gets into robotics does the " boring" stuff. if you go to a top tier university and just BTFO every course, maybe you could get into it, but i'm pretty sure that if you are posting on 4chan about it, you won't be able to pass the cut.

because our eyes are aligned horizontally, not vertically.

>>7652534
also your 3D axes do not form a direct trihedron

I have no idea if it shows the most promise, but metallic nanoparticles are probably something you haven't heard of.

>shoot them infrared lasers that pass harmlessly through most flesh but are resonant with nanospheres, literally cooking the tumors and leaving the rest unharmed

It sounds implausible, but they're actually doing this shit.

>>7652523
Why gold? And would they remove the spheres afterwards? Could you just have bi-yearly check-ups using this?

>>7652529
because gold is really conductive.
