If I were to buy Uranium marbles and place them in this person's bag, or under their bed, how long approx. until they got cancer?

couldnt the police see the uranium in the dead persons body and see that Retard OP made a recent purchase of uranium
>>
>>7970051

Not in that for OP. You'll need to make the uranium unstable. Easiest way to do is bombard it with protons and make plutonium. Just go to a hospital and say you have cancer. Ask for proton therapy and sneak it under your clothes. It should become radioactive in no time.

I see a lot of hate for the mods, but if you look at /sci/ archives, you find that they delete a lot of shit threads. Look at the link below for examples. 8 shit threads deleted in 16 hours.

The problem is that you faggots decide to reply to these threads, instead of reporting and hiding them. If you complain about mods, but are one of the faggots who replies to shit threads, and you don't report shit threads, you are the cancer killing /sci/

When r9k and pol start a discussion, it's a criclejerk full of low quality posts. There are boards for that shit, you know?

This "environment" repels some posters which make those q/a interesting threads and some eventual happening, for example.

IQ and statistic demographics are good, unfortunately, those threads derail to pol shitposting and r9k circlejerk.

Is /sci/ interested in books and shows about science fiction? Realistic ones, say, with actual science
13 posts and 3 images submitted.
>>
>>7969349
yes.
Also, much of science fiction has basis in real science. Probably not the movies/books you've been subjected to. A lot of sci-fi books have realities that are theoretically possible, or totally possible just maybe not logical if said logic is to be applied to the world you and I live in.
Authors like Isaac Asimov and Arthur C Clarke.
Ray Bradbury is a good author as well but many of his stories or closer to fantasy than sci fi.

What about a book set in the very near future, with weaponry that's only just beyond our scientific grasp today?

I am taking an intro to physics class, physics 101 essentially, the professor is a goddamn nincompoop. He doesn't know anything, it's so sad and pathetic can someone here help me on my journey of discovery. Can someone here on /sci/ help a anon out. I am a biochemist and I have never taken a single physics class not even in high school.

You know calc? Apply calc to the material. Use MIT open courseware and the many free tutorial sites. Those are kinematic learn force diagrams and their rules.

I would like to study math here following my undergrad. I plan on not taking the entrance exam, and instead applying with the personal package. I am currently enrolled in an honours math program at a top 15 university. I have 3.95/4.00 GPA and pretty extensive research experience+publications. What mathematics topics are necessary? What else can I do to beef up my application? Do I even stand a remote chance of getting an interview?

To keep it /sci/ related, also general discussion of the entrance exam. Here's a sample exam:

you link a subject for biology students.

what do you study and what do you want to do ?
>>
>>7969052
Oh really? That test is math for bio students? I may be worse off than I thought then.

I have been involved mostly in combinatorics and graph theory projects including the Bruhat graph combinatorics and forbidden Berge subgraphs problems. I have also been involved in a few projects in mathematical biology and one in space physics. I hope to study pure math at ENS. I would like to study rings but I don't have experience in this area beyond my coursework

wait what do bio students even need math for?

If the sun were scaled down to the size of a tennis ball, how hot would it be?
Could we hold it in our palm?

Note, scaled down to size, not "compressed" down to size.

That doesn't make sense anon. You can't scale down atoms of hydrogen and helium.
Even if you could shrink it somehow why would that affect it's temperature?

Is real life "memoryless". That is, does where the universe go next depend entirely on its current state only, or does one need to know the history of the universe in order to predict its future?

Both.

It will be perpetuated by events of the past, of course, but inductive reasoning will only get a human so far.

Hello /sci/ I was in physics lecture (waves and optics) and I asked the professor if the intensity maximum of slit experiment light increases if the number of slits increases.

At first he thought they did not and the intensity remained the same, but then I talked to him again after class and expressed how I thought the intensity would increase as a function of the integral.

Online MIT and Georgia Tech lecture notes always show the maximum intensity as one as the attached image shows. Is this correct? I think the intensity would increase as the interference decreased. Where is that energy going?

Thanks!

Total area is conserved so peak heights must increase.
>>
>>7968952
That is what I was thinking, could you explain why the area must be conserved?

Also why does MIT and Georgia Tech both have it wrong? I guess NYU as well because the professor did it wrong at first.
>>
>>7968949
as the number of slits increase, the distance between each slit decreases (we want to keep the original area that light strikes the same to ensure we are always talking about the same incoming energy). We know that for diffraction gratings, m=d/lambda where 2m+1=max number of bright spots. Since d decreases, m also decreases and the total intensity f course stays the same. So it seems you're correct that the more slits a grating has the higher the intensity of each spot.

Hey /sci/, I've been busting my ass with gen end courses and have about 3.7 but I'm about to start getting into the physics/Math courses making up the bulk of my engineering major.

This summer, I'm deciding on getting a tutor or two in order to help me set a strong foundation in order to really grasp and get a semantic understanding of the maths and physics needed.

I want to get to Calc 3 Levels and pretty high in physics.

Are there any subjects that you guys recommend for me to really focus on over summer for a MechE degree which may eventually evolve to Nuclear?

I'm currently just in my second semester.
