My undergrad went
1 Intro linear algebra
2 Rings and fields (baby Hungerford), more linear algebra (Axler)
3 Group theory (Armstrong), reflection groups (Humphreys), Galois theory
4 Algebra (Dummit/Foote), Commutative/homological (Eisenbud/Matsumura/etc.), Representation theory (Vinberg)

I think I turned out all right, I think groups could have come earlier though

>>8046981
Are these separate courses?

>>8046982
Yes, with the textbooks used for each one

I probably took an above average number of algebra classes

>>8046844
Since bullets are generally made of lead, no

>>8046848
arent all materials at least a bit conductive, i mean isnt there an amoun tof electric charge that will repel it?

>>8046873
No, fuck you

Nope. None at all. Battery technology is advancing, jusf not exponentially.

>>8046840
Battery development is pretty slow, hard work right now. It's unlikely we're going to see any large jumps in performance any time soon.

>>8046840
Really? I've heard battery time is increasing logarithmically and will slow down significantly in a couple decades if new technologies aren't developed.

>>8046772
tbqh I'm not even sure how the new board works with all the dice rolls an shit. Seems like an expanded /tg/ dedicated to separate games per thread.

>Say there were a hardcore science story driven slow-form RPG on /qst/, where you would put your education to use solving technical problems, designing, collaborating, not-so-collaborating, etc.
Examples?

I guess individual posters could participate, but I doubt /sci/ as a group could collaborate on a single thread.

>>8046783
In its current early stages, when broken down to really basic levels it would follow a format something like this:

>Problem is proposed by the OP
>Players suggest solutions to problem, work together to form a coherent, objective solution
>Problem will be solved
>New problem will arise

Obviously that would get pretty repetitive.
And of course, that begs the question of how does the OP create the problem, in what way should it be presented, how can anyone feel welcome to participate on a given problem, in such a diversely complex umbrella field of science and mathematics, when individual problems require individual sub-fields.

A lot of big issues to tackle.

>>8046794
Thanks for spoon-feeding me anon, seems interesting after all. Also, where do the dice rolls come in in your proposed format?

Anyway, the problem I see is that for someone to actually propose a scientifically literate problem... well, they would have to be /sci/ themselves, which in turn means only /sci/ autists would be able to solve the problem and so forth, which would result in /sci/ exclusive threads, which I just don't see happening.

You could propose an example here and cross post it to see how it would go, but don't keep your hopes up. The only thing /sci/ can offer IMO is individual creativity and problem-solving skills based on a fundamental understanding of science, but not actual applied scientific knowledge because of what I explained above.

The radiation levels in the worst-hit areas of the reactor building have been estimated to be 5.6 roentgens per second (R/s), equivalent to more than 20,000 roentgens per hour. A lethal dose is around 500 roentgens (~5 Gy) over 5 hours, so in some areas, unprotected workers received fatal doses in less than a minute.

I'd rather we discuss the much more interesting biological effects of Chernobyl. Higher percentages of birth defects in the area for example. Panic over the effects of the spread of radiation. Also, dank radiation-powered fungi growing in the walls of the reactor ruins. Cool stuff.

>>8046570
Radiotrophic fungus is some cool shit actually. Imagine space travel using that stuff as one of your food sources.

shills, that's why

>>8046495
I'm no doctor bit you need to control cost and additivity. And history and what your taking

>>8046495
I've always kind of got the impression in doctors offices that they are always on the lookout for people acting sick just to get the good stuff. So they are a little more hesitant to give it out. Plus it would look bad if their boss saw they prescribed 40 people with benzos in the last few weeks. Also in the medical world (at least in the navy) you are taught to try the easiest cheapest treatment first. Then, if that doesn't work, move on to the more expensive ones. That's why the famous "drink water, take motrin, change your socks for a broken leg" joke is true. I get free medical treatment through my job and I went in to get my chest scanned for lumps and they gave me an x-ray first. At least in my understanding an x-ray will only pick up bones, but they insisted on doing it first before they gave me a real cat scan.

replace

>>8046399
I don't. I know exactly what I'm talking about and that chart is all kinds of out of order.

>Number Theory after Galois Theory
>Smooth Manifolds after Algebraic Topology
>Grobner Basis that fucking high
>Complex Analysis after Abstract Algebra

Terrible list.

Normal numbers are base 10. Binary is base 2. This means the columns represent values of 1, 2, 4, 8, 16 instead of 1, 10, 100, 1000. You "carry the 1" when a column gets to 2 instead of 10.

The value 0b1011 in binary is 1+2+8 = 11.


In programming binary can be used to represent things other than simple numbers. For example a game programmer could make different bits of a byte indicate what items a player has possession of.

>>8046332
>Normal numbers are base 10
10 in what base :^)

expounding on the previous anon's post, this is essentially how addition is performed in computers on adders. Depending on how much detail you want, you may want to look into computer architecture to see why binary is convenient and necessary. It may also help you understand more.

And here's a visibility chart. As you see, the entire transit will be visible for the eastern North America, Western Europe, and most of South America. Most of the rest of the world will get to see at least part of the transit. Sorry Australia and east Asia; you're fucked.

How do you even view this?

Pretty much all of modern drug development relies at least to some level on animal testing for essential data to encourage cure development.

https://en.wikipedia.org/wiki/Animal_testing
>Supporters of the use of animals in experiments, such as the British Royal Society, argue that virtually every medical achievement in the 20th century relied on the use of animals in some way.

>>8046183
I don't know, but we've prevented the deaths of at least hundreds of thousands of humans by testing on animals first.

Most drug designs are complete failures that never make it to human trials.

a LOT of ageing related research is done with mice

>I didn't get into my dream graduate schools for physics, but by contacting someone my professor knows, I have until tomorrow afternoon to decide whether I want to go to West Virginia University for a physics PhD or not, what would you do?

>Not getting in based on merit
Degenerate. Who cares what I think. Go for it if it's your dream school

>physics PhD

>>8046131
Here's more context:

So WVU isn't his dream school. There's another catch too: he'd be going there for numerical relativity (it's what he's done research in for the past 3 years as an undergraduate). But his true interests lie in mathematical physics.

Are you pigeonholed in physics? For example, for medical students, residency matters more than the medical school they pick, especially for what they end up doing at the end of it all. Does physics have a degree of flexibility to it, or will he forever be doing numerical relativity if he chooses this?

>>8046079
Christ - you'd think with a multi-billion dollar mission they could have loaded the probe with a better camera. My iPhone takes better pictures than that.

It's probably due to data transmission limitations.
