What sort of answer are you looking for?

You seem to know applications.
It's common for existence statements with simple condition to be relevant shortcuts. Like the fixed point theorems.

>>8606672
>has a few other applications; but is that it?
I don't understand your point. What else do you want? Do you wish for it to keep your beer cold? Like seriously, what else do you expect from a theorem other than using it in proofs for other theorems or for direct application, what else could there possibly be?

probably some cool stuff too bad we won't be around to see it.

Bump.

>>8605328
So you got a degree, just not in science or engineering?

I don't know the answer. What you find fun/useful is a personal thing.

>>8605333

I got an engineering degree at a shit low standard university.

>>8605328
Why is my question?>>8605328

Higgs boson

Energy divided by the square of the speed of light.

It is the physical property of an object to resist acceleration when there is an external force applied to it. It also determines its mutual gravitational attraction to other bodies of mass. Look up Mass-Energy for more information on the relativistic concept of mass.

just brute force it, man

>>8603886
explain how that game works

Fuckin magic man we ain't gotta explain shit

its pretty complicated according to Feynman.

To break it down, for ferromagnets the free energy is the lowest in state where spins of some electrons align in the same direction. There is also paramagnetism, ferrimagnetism, antiferromagnetism and diamagnetism but this is left as an exercise for the reader.

You should probably just Bs in Physics or EE and go to grad school for Nuke

>>8603310

Don't be an idiot. Be single major.
Virtually no career requires a double major.
Double major is stressful, and takes all of your time to pass the courses.

Just do EE. Interesting, challenging, and employable.

>>8602816
whats the difference

>>8602816

Pst. Pro-tips.

1. If you really need the book, go to the library, take out your phone, take a bunch of snapshots, and then study digitally on your iPad or whatever.
2. You don't need the book 99% of the time. Study your notes and maybe take a voice recording of the professor if that helps.

>>8602828
I'll need it later down the road, plus once I'm out of college.

I don't mind shelling out $24 on a book, just not $320

1,000 years

because I want to witness cyborgs and the end of ageing

no more than 100 years

Because any further than that and humanity will be extinct and the planet will be an uninhabitable rock

leonardo what are you doing here

>>8602102
dude man Perelman proved the Poincare conjecture (and really went quite a bit beyond it) Tao man is BTFO in comparison with that.

Tao is basically a polymath of math, so Tao. Also, Tao's IQ is much higher.

Nice resolution.

Yes, they are very difficult to express, purify, and crystallize.

For some reason it's much harder to get E. coli to express membrane proteins than any other type, at least in any meaningful amount, without killing the cell.

Purification and crystallization are also tough because, since it's a membrane protein, correct conformation often depends on the presence of a lipid bilayer for the transmembrane domains. If you don't have that layer, you might not fold the protein correctly, which means any structure you crystallize might be just plain wrong.

Usually people get around this by expressing just the free domains of a protein, but this again has its issues. You don't know that the protein folded correctly without the transmembrane domain. Also, if your protein has a multi-pass structure and the tertiary structure depends on the loops between passes being present, again, you might not fold correctly.

We've run into this problem a lot in our lab because the membrane protein we're interested has a good deal of sequence similarity to bacterial histidine kinases, so we think it might actually be functionally active in E. coli in a way that kills the cell.

> we think it might actually be functionally active in E. coli in a way that kills the cell
Thats like one of the common lame excuses for laziness
>Hurr my protein is toxic, i cant express it, so i cant raise antibody
Not in your case of course

I'm in the same boat with you anon, well kinda. I wanna do something with engineering, geography and traveling.
I don't know how it is there but here you can become a survey tech right out of high school and pretty much work your way up to survey manager which is practically civil engineering (I think, that's what i've heard)
Have you taken any classes on Geomatics or any other survey related fields?

>>8606860
I'm a geology major myself so we do work some in GIS and Geomatics. That would be my suggestion. We have an entire Geomatics department at my university. Surely a degree there would qualify someone for surveying.

>>8606860
here you have to have atleast 2-3 yrs study to became a technician or a 4 year bachelor to be a surveyor plus i think 2yrs for license.. i think.

i have not taken any classes yet, but im planning on studying to became a tech in February.

Because of the Earth's rotation about it's axis, correct?

>>8606720
>Earth's axis is parallel to its ecliptic
Do you mean to say 'Earth's axis is perpendicular to the equator'?

>>8606748
It's the way that answer is worded. I dislike these kind of questions because I feel it could have two or more answers... This is for a "physical geology" course by the way.

>>8606682
I looked at the NASA website, gonna need a more layman explanation.

>>8606682
>>8606686
ok I actually found a resource for finding the mach number via mach angle.

Now I just need to know how to properly measure mach angle on an rectangular object.
