what are u talkin bout OP
mee to thanks
yau is a cunt
so im gonna do a six year dou le degree in electrical engineering and computer science. how do i get a get a job during it and maintain my studies? obviously staying at home for 6 years while studying isnt a good plan
>>8608539
Time management and no video games, anime, or fapping.
>>8608560
hahahhahahahahahahahaha
dude i cant do it.
my life is ending.
i sleep from 9 a.m. to 6 p.m. and am awake at night. HELP ME

someone explain how I know which is x1,y1,etc

I want to go to grad school for bio since shit like CRISPR fascinates the fuck out of me. But I know that the chances of me getting into a good grad school, wanting to stick through grad school, and finding a good job after grad school isn't assured. I'm thinking it would be better to get my bachelors with something more marketable like chem eng rather than bio or bio eng so that way if anything happens, I could go out and get a decent career in something that still interests me. But chem eng would cause issues for me going into a bio grad program wouldn't it?
advice?
>>8608447
>what is grad school ?
going through a school's doctorate program.
>>8608444
You're dreaming. Bio lab monkeys make minimum wage and unless you're Einstein-tier, you're not going to be doing anything meaningful.
Doesn't it frighten you that elementary particles are going to exist for eternity?

Why should it? Justify that fear.

Starting linear alg, O Chem 101 essentially, and waves/optics/thermodynamics phys next quarter. Any bits of help you guys can give me?
>>8608388
Don't take ochem lightly.
Lin. Algebra helps if you took ode.
The physics will be mostly plug and chug with some minor results proven for thermo.
>>8608388
get a feel for linear by reading ahead.
pray you have a proofs based course, it will help you with all physics forever
>>8608395
I'll have to take your word for it. I fucking hate proofs.
Hey, /sci/. Can we have a discussion? Not really questions that need to be answered, just thoughts on a subject.
I was pondering pressure washers. I got to wondering. Since we use them in industry to cut things, very cleanly and cooly, as opposed to using saw blades or drills, I was curious exactly how much pressure can you put water under before it becomes steam or plasma?
Lets suppose we could construct something with the materials science needed, okay? So for the purposes of this thoughtsmithing, they're made of unobtanium. We can discuss exactly how hard they'd need to be after we figure out how high it can possibly go pressure-wise.
Given the properties of common water, exactly how much cutting force could be applied? I'm not sure on how wide the nozzle would be. But lets assume we want a tool or a weapon capable of wasting the treads on tanks, or the hulls of ships.
How much PSI would be needed? And how far away could it be fired from and maintain enough pressure to do the deed? Clearly it's unlikely that something with the reach of a garden or firehose is going to be blasting tanks apart, but work with me here.

>how much pressure can you put water under before it becomes steam or plasma?
You've never had high school chemistry?
https://en.wikipedia.org/wiki/Phase_diagram
>>8608383
tl;dr: I never took it.
>>8608380
See:http://scienceline.ucsb.edu/getkey.php?key=3257
Long story short..
While the first order state changes (solid, water, liquid) are very different from the second order state change, gas-plasma.
There is no latent heat involved, meaning it doesn't happen sudden but rather gradually.
Also while the first order changes are dependent on temp and pressure(mass), the gas->plasma change is dependent on temp, but instead pressure(magnetic).
Long story short, you need to add temperature, pressure(mass) alone wont do it.
Diamond is metal , its in fact the hardest metal known to mankind , prove me wrong.

diamond is carbon.

So cells cant be created or destroyed, and they're recycled.
So that means that the we have the cells that belonged to dinosaurs, and before that to planets.
My question is (which i cant find online) why are we humans rather than dinosaurs or other reptile type creatures? Thanks

>So cells cant be created or destroyed, and they're recycled.
No. That's not true at all.

For time dependent 3-dim vectors [math] {\bf v} , {\bf b} [/math] and constant c,
I'm dealing with an differential equation of the form
[math] \dfrac{d}{dt} {\bf v} = c {\bf b} + {\bf b} \times {\bf v} [/math]
Does anyone recognize this type form any other setting?
For c=0 we have that [math] L = {\bf b} \times [/math] is just a linear map and I know that
[math] \dfrac{d}{dt} {\bf v} = L {\bf v} [/math]
is solved via

Mostly, I want to know what known discretization schemes available. For the first equation. Maybe there's something in fluid-dynamics, hydro-dynamics or electromagnetic field theory like that. (E.g. a text on the discretization of the Newton equation for the Lorentz force)
>>8607966
How about writing it using 4x4 matrix L. Append a 1 to v to make it 4x1. Use Magnus again
>>8608350
This.
Kind of looks like the Landau-Lifshitz-Gilbert equation for magnetodynamics if you define v as M and b as (M x H_eff). There are some notes on it on the internet for numerical solutions. Hope this helps!

Is being 27 too old to restore your natural test levels and recover from a live of chemical products filled with strogen?
>>8607939
Yes, unless you're still in puberty at that age.
>>8607949
how do I unfuck all those years taking strogens in my food, shampoo, and meat?
>>8607954
Stop using the useless products, such as shaving cream when you can wet shave.
Start eating lots of cruciferous vegetables and legumes, lots of variety, try to eat local if local isn't too polluted. Avoid processed, canned and frozen. Eat fresh.
You have established drugs of choice that are going to be torturous to stop; and one of your drugs of choice has been to eat lazily and put lots of chemicals on your body, cause that's what you were taught to do (e.g., taught and shown to clean chemically, the magic way, rather than actually using physical work to scrub away dirt and dead skin). It is doubtful you will change positively on your own; most people need tornadoes, hurricane, floods, tsunamis or earthquakes to move them and even then it rarely changes them.

A-am I still getting into grad school?
>>8607911
You don't deserve to get in given that you are an admitted cheater.
>>8607913
But people get falsely accused all the time. Could the grad schools will give me the benefit of the doubt since it only happened once?

Too many people are applying so no.
