Where can a normal everyday civilian buy raw uranium 238? I don't see where possessing it would be illegal.

thanks!
From making bombs alone you can calculate there are enormous amounts of U238 (known as depleted uranium) lying around. And there are no good uses for this really other than for research in fast breeder reactors and ammunition.
I hear it can be used for armor around jet engine turbine section to prevent turbine failure from slicing through the aircraft like knife through hot butter but that is not such a huge demand either.
So if you can find a good use for all this the US is all ears.
After oxbridge, what are the best non-US universities?
I'm thinking of Maths or Physics, in case that helps.
Ecole normale supérieur in Paris, but it's not really a University.
Then ETH is probably the right call.
>>7771611
ETH and EPFL are about the same for the sciences. ETH is bigger because it contains everything while EPFL is only engineering

Hello /sci/
I've been given a little thought experiment that I'd like to pass on to you, it goes like this:
You have a cube with sidelengths 1m.
You then take a drill which has a diameter of 1m, and drill through the cube from all sides, so that you end up with pic related.
Now, how do you determine the volume that is left after drilling?
just integrate one of the points and multiply by 8

So this is how it feels to talk with a retarded person.

Just give him shit he won't understand
So sci bc because of my curiosity, do any of you know of a portable power source that holds more "juice" than any other portable power source? I'm talking raw power not like an iphone charger or some lower tier BS like that.

I've recently gotten a sudden urge to learn maths from the ground up.
I have a very scattered education on math so most of it doesn't make sense to me. That's why I want to learn from the very beginning and make my way to the VERY advanced stuff.
I know this isn't going to be a walk in the park. It's going to take years and there's a chance I'll just fall behind and stop.
But at the moment I'm very determined to learn all I can and I need your help.
Where do I start. Where do I go? I found this chart on the /sci/ wiki but...

Anyone? I'm in need of some hardcore help here.
Also while we're at it, if anyone needs help learning certain types of math, they can post in this thread.
It was a bit selfish of me to just want the thread about teaching me.
I only minored in math so I dont know if I can speak to the 'very advanced' stuff.
If you're doing this for yourself I would go on Kahn Academy and just do the natural progression they've laid out. Something like Alg.1->geomtry->Alg.2->Pre Calc->all the calc courses->DEs->Linear alg.->etc. If you already understand a topic skip over it. Kahn explains maths a lot better than most textbooks will. It will give you a pretty good foundation to go explore whatever you find interesting afterwards.

so, had an interesting chat with a creationist, and he posted this gem, i wonder how you guys might respond to such a statement, because i'd like to know how to accurately respond to this in the future.
There's different animals alive right now that look "morphologically contiguous" to eachother.
>If bobcats were extinct animals, and domestic house cats were extinct animals from an earlier time period, they would line up their fossils together and claim that the house cat evolved into the bobcat.
>>7771164
He's right,
but it's not an argument for creationism.
>>7771164
In a way it's kind of true.
You could analyze their morphology relative to whatever "ancestors" or "descendants" you found (i.e. before cats and after bobcats), but assuming this is just a simple thought experiment, then no, you wouldn't really be able to tell the difference.
At the same time, in the fossil record you don't know what species evolved into what species. You just know that they are kin. You don't know if there is a direct ancestry there. Just like...

>>7771174
Me again. Let me put it this way.
If you found a house cat skeleton and a bobcat skeleton, you could say that the bobcat is related to that house cat. Related. You CANNOT say that the bobcat is a direct descendant from that house cat. For all you know, house cats and bobcats could have shared a common ancestor (let's call it desert cat), an in this case bobcats would NOT have been descendants/evolved from house cats, even though the fossil record could have made it looked like it.
why aren't we funding this guy??? clearly the work of an unprecendented genius

Greetings from /biz/
Trying to into financial modeling
Has anyone heard of monte carlo models and does it really work?
>>7771098
>Has anyone heard of monte carlo models
Yes.
>and does it really work?
Yes.
Any more stupid questions?
What the fuck do you mean "does it work"
Monte Carlo always works but is so slow that it usually seen as a "last resort" when faster algorithms can't be used.
I lost my parents as a teenager and became homeless. I missed out on high school education, but I've been saving up money to go to college for the last 5 years. I still have about a year of saving before I feel comfortable going to school with enough money to fall back on. I want to major in aerospace engineering by attending a community college and then transferring to a major university (there is a good school and program in my area to do this).
Has anyone here succeeded in college without a strong background of education and support?
What should I be learning on my own before I attend school?
>>7771027
>aerospace
About 30 years too late, fampai
>>7771027
Large universities have support structures for people in your position. Community college may be rougher. Aerospace is a crowded field.
However a lot of fresh out of highschool undergrads lack discipline to get all that they can out of their degree. What you lack in youth. You make up for in having your shit together.
Are you in Dallas by chance?
>>7771027
I never went to school and wasn't given education beyond basic numeracy and reading/writing.
I am now studying engineering a top uni. It's possible if you have the brains and the dedication. I wouldn't class myself as exceptional among my class and I think the average engineer would be capable of doing the same so you don't have to be a genius, just capable of being an engineer.
What I did:
1: got all the books for the entrance exams
2: found a place that would allow me to sit...

Hey /sci/ I need help.
Im trying to learn/teach myself pre-calc.
Can anyone give me a good and preferably free source to learn pre-calc? One that would give me a strong understanding of the concepts.
Much Appreciated.
Check the /sci/ guide next time.
https://sites.google.com/site/scienceandmathguide/subjects/mathematics
There is no subject called "pre-calculus." You should have a very good understanding of elementary algebra, trigonometry, and know your basic rules for dealing with functions.
Calculus is fairly easy. I'd say there's more online resources than one could count.

Most of what I've read indicates that the really big invertebrates (insects, spiders, etc.) of ages past disappeared due to falling oxygen levels. Let's say a person with a fairly large amount of cash created a sealed hyper-oxygenated environment, say the size of a warehouse, and began selectively breeding modern insects and arachnids for size along with providing them an ideal diet for growth. Could that person get bugs the size of the ones of the Permian period? If so roughly how many generations do you think it would take and what insects or arachnids would be ideal...

Come on, man.
Couldn't you have asked a serious question?
>>7770953
I'm seriously curious if such a thing is actually possible, basically are there any other roadblocks to giant insects other than the oxygen level in the atmosphere?

Would I be able to go into research with a bachelor's in engineering? If I changed my mind once I'm done
And if so, for which engineering degrees does this apply to?
Is engineering a good route to research? If I obtained a non engineering masters? And if so, what kind of masters complements a bachelors of engineering well?

How do I raise my IQ 5 points? Its 138 and I would like for it to be over 140.
practise pattern solving
>>7770846
140 - 138 = 2
You only need 2 more points, not 5.
Stupid brainlet.
>>7770846
every time you make an IQ thread on /sci/ you lose 0.999... IQ points
