So this Fall I'm starting in an Engineering program, hoping to specialize in Mining. Are there any tips on how to get 80's or higher while not burning out? Does group work make for the best methodology to get through the work or should I keep my to my hermetic ways?
Also, general thread related to Engineering.

you should have picked applied math to make that cash
Do really good on homework and tests and you can easily get good grades.
>>8094776
Get a fucking work ethic, grow the fuck up and do your god damn homework you lazy sack of shit. That's how.
Also engineering specifically: learn to love the cock.
Yay!

nice interview
good the numberfile guy doesn't talk all too much (I mean that as an honest compliment to a reporter)
The idea of cooling typically gaseous elements to a liquid/solid/superfluid intrigues me, especially:
>Although colorless at standard temperature and pressure, when cooled below its freezing point of 202 K (−71 °C; −96 °F), radon emits a brilliant radioluminescence that turns from yellow to orange-red as the temperature lowers.
Are there any images of this effect? (or any other solid/liquid noble gas for that matter)
have a bump OP
Interested

I believe that physicists who take their models as literal interpretations of physical systems to be morons. For example,
> heuuuuu space and time are the same thing!
> heuuuuu spacetime curves!
Yes, with these assumptions/consequences, we find a very successful mathematical models that gives us correct predictions. However, this by no means ensures us that the physical system is in fact the way it is described by the model.
Another example: With Newtonian gravitation we may be able to describe...

MWI is terrifying, i don't see how any sane person would want to believe it
Why haven't we discovered the process that leads to self-awareness yet? The anatomy is there, the regulation of everything in our bodies is done through electrical impulses or chemical vesicles and the mechanisms for a large part of those are well-understood. So, how do a bunch of neurons sending APs across your brain form coherent thought and self-awareness? A computer is not self-aware, so processing information isn't what concerns me here, although it's still very interesting. I'm genuinely not trolling, it just baffles me to see it unresolved.

Opie, there are trillions of cells in the human body.
We have only the vaguest generalized sense of what's going on.
Come back in a thousand years and ask again.
>magnitude of cross product gives you the area between 2 vectors
>triple product gives you the volume between 3 vectors
How do you generalize into higher dimensions?

Science degree or trade school? Which one earns more generally salary wise?
>>8094263
trade school
>>8094263
Too many variables.
Assume you're talking about a BS/BA in science. Does the science degree go to grad school, then do a post-doc, then stay in academia? Does the science degree go to industry after undergrad? After grad school? Does the science degree stay in R&D, or move to the business side?
>>8094263
Trade school all day long.
At least then you'll have the option of doing a science degree afterwards and having a trade to fall back on. You'll be working well into your 70's these days, there's plenty of time.
ls there any lRC out there where l could ask small questions about maths or/and physics?
no. i used to believe in a world of infinite cool internet people as well. doesn't exist.
gl, OP.
Do what I do. Look up the math/physics dept on a random college's website, pick a likely email address from the staff directory and tell them you're a student in one of their classes and you're curious about _____.
Helps to cross reference with the course catalog, so you can see what classes they're teaching and lie more effectively. All that info is usually public.
>>8094276
why don't ask your own teachers instead? lmao
By using normal weapons and with no resistance could a single man kill every human?
Thinking of how many babies are born on a global scale compared to how many people he would be able to put down.
>normal weapons
If I have access to 'normal' weapons I'll just nuke everyone.
gg let's play again sometime op when you have a better game.
>>8094216
If you killed one person per second, it would take about 220 years to kill everyone on earth, so no.
>>8094246
what if you used bombs
you could kill thousands of people a second
Can someone explain me just how much Bacteria is there in our environment and when exactly does it get harmful and just what harm can it cause?
Some example scenarios:
You take your laptop with you in college. There you put it on the tables that are used by many people. Let's say you let a guy type on it who didn't wash his hands after the toilet. At home you take that laptop in your bed and after using it you don't wash your hands and continue to touch things inside your house. What can happen?
Or if you use the keyboard in the college library that probably hasn't been washed in a long time. And then with the same hands eat a sandwich.
Or you drink a soda that you bought in a store straight from the can.
Or you step over dried bird crap that didn't stick and then take those shoes inside home.
Or you have a dog that jumps around the house and your furniture.
Or you touch the faucet in a public toilet. Isn't that full with bacteria?
And just what would happen if you sat down with you bare ass in a public toilet?
And what if despite shaking your dingus the last drop ends in your pants?
What can happen if you eat food at a cheap place that doesn't respect hygiene too much?

You could attain a stronger immune system, or get a cold or things of that nature if you're unlucky. Basically unless the news headlines says 'SARS' , 'Ebola' or similar nothing very bad will happen as a result.
there are bacteria everywhere, they live on you, they live in you, they eat your shit, they shit where you eat, you eat their shit, you cannot stop them, you need them, they can kill you
your skin is an excellent barrier, your immune system is an awesome killer, just wash your fucking hands, and don't be a germophobic dingus
https://en.wikipedia.org/wiki/Human_microbiota
You are surrounded by bacteria literally every moment of your life. Countless bacteria are living and reproducing in your gut right now.
Passive exposure to bacteria is generally beneficial, and is considered essential to the development of your immune system as a child.
Bacteria are only bad when the wrong kind get inside you and reproduce without control.
For example, the Staphylococcus bacteria that causes deadly staph infections, lives natively on your skin. It's always there. It only can kill you if it gets past your skin.
Tl;dr, bacteria is everywhere....

What is the logic behind pic related?
I'm sure there is a reason for it, but I was never taught it and its always bothered me.
For example, whenever I do the quad formula
if -4ac turns out possessive (and following the Order of operations exponents, multiply, add/subtract) I always end up with something looking like 17 153, and multiply instead of adding.
Can anyone explain why we are taught to write like this?
>>8094202
>possessive
positive. Fuck auto correct.
>a - b(-c) = ab
>>8094217
8 -5(-5) if you follow the order of operations and multiply -5 * -5 the problem now looks like 8 25.
Basically why is it that when 2 positive numbers are next to each other, by default it's assumed you are suppose to multiply, but when 2 negative numbers are together you are suppose to subtract?
Example:
if a and b are both positive, and you see
[math]ab[/math]
You know to multiply, even though if you write it out ab comes out as
[math]+a+b[/math]
and
[math]-a-b[/math]
means...

Can /sci/ recommend me a good book for Differential Geometry? Something I could learn from on my own
>>8094070
Lee's smooth manifolds. Spells everything out, hence very suitable for home study.
>>8094080
I just took a look at Lee. i think we aren't studying it so deep. We started with parametric curves in R^2 and R^3 (Tangent, Normal, binormal base). Then we got to elementary parametric surfaces with geodesic curves, first and second fundamental forms, asymptotic lines.
I need something like that for further reading

We'd have a huge surplus of burger-flippers, low-end wages would fall.
