>Laughed profusely and wrote in the test , 'kill yourself desu senpai'

Hold me guys
you told a student to kill himself after getting a 0, whatre you expecting
Sounds like you're a shit teacher. I hope you get fired.

I joke with my students all the time ;_;

He's black so most likely yes, i will get fired
Has anyone here seen a reaction between Francium and water? What's it like?
>>7664709
>Has anyone here seen a reaction between Francium and water? What's it like?
There's 13g of Francium on the whole planet, so no
It's probably similar to the other alkali metals but not as energetic as Cesium since its highly radioactive. This might be why there's no videos of it because it decays quickly.
>>7664730
You could hypothetically synthesize francium and do it, so maybe.
Also where'd you get this 13g estimate? That's oddly specific.
Hello, I'm doing a program and I have been stuck for a while.
Imagine I want to move the blue dot to the red dot through the smallest path, d, by clicking on the screen (red dot).
I tried many different ways but the blue dot won't ever go through the coordinates I pressed, it seems to act kinda randomly.
How do I make it move to where I pressed?
Basically I want to get vx and vy.
Using java.
>Inb4 >>>/g/
I literally have not the foggiest idea.
Try asking /g/ in the programming general.

If you're really set against /g/ then stack overflow could be helpful
Hey guys was wondering if I could get some help. My mammalian physiology class is doing case studies and I'm honestly not sure how to go about the first question. Any ideas?
1. An agonist is an agent that reacts with a receptor and mimics the action that normally results from the binding of a transmitter to that receptor. Thus a muscarinic agonist mimics the effects of acetylcholine to a muscarinic receptor. An antagonist blocks the action that normally results from the binding of a transmitter to a particular receptor. Thus a β-adrenergic antagonist blocks the actions of epinephrine (a β-adrenergic agonist) that normally result from its binding to a β-adrenergic receptor. Assuming that you had an agonist and an antagonist for every autonomic transmitter receptor, how could you determine which receptor types exist in any autonomically controlled effector?
You would add selective antagonists to each of the suspected receptors and see which antagonist blocked the response of the endogenous ligand.

Did you get that from Yahoo? Just wondering if two different sources are saying the same thing or if it's only one source being repeated?

y-you guys...
Why do people say "ow"?
>>7664475
Goddamn, I can hardly deal with this apsergers autist shit so early in the morning.
Why do people make that sound? Clear enough?
Do other languages say something other than "ow" ?

Yes.

What makes the universe consistent? as much chaos as there is. i mean on a miniature scale have accident or 'glitches' occurred?
self-organizing system, life-like
glitches do occur but are not 'fatal'

What makes math beautiful to you? Is it the patterns or the relationships between different subfields?
pure logical reasoning is pretty fun
>>7665016
this desu. It's fascinating that we could come up with hundreds upon thousands of theorems and ways to explain the universe by building upon a relatively small amount of axioms.

A while ago I suggested increasing rocket thrust through the atmosphere by exhausting it horizontally over a Coanda surface before finally pointing it downwards and /sci/ was typically dismissive calling me a "free energy nut" and all sorts. So explain to me if fast moving fluid over a surface does not induce atmospheric pressure underneath it then why does a piece of paper lift up when you blow air over the top of it? Try it now.
they did
>>7664545
link? why did it flop?
The issue is your exhaust has momentum and won't hug the conada surface tightly when its moving at a mach multiple.
Also it's hot, nozzle bells have active cooling.
So, my old $210 refurbished Dell PC finally imploded after about 2 years. I'm getting a new one with gaming components in it, but as I hear from my friends in The Netherlands, they need higher-performance PCs for Bio-Lab simulations, pictures, programs, etc.
I'm at a massive point where I'm at 'generals' in school and I don't give a fuck anymore, Calc 3 and Mechanics Of Materials, the latter taught by the most sporadic person I've ever been forced under, and the former difficulty but not impossible.
M8s I need higher level stuff to keep interested.
I never learned the following:
Creo/CAD, MATlab, Arduino, C++, Java
I really want to get into modeling and/or simulations.
What would /sci/ reccomend I do with this new hardware, now that I'm able to run shit, for more interest in this field with stuff that is relevant?
Sorry for great wall of text.

And this is why university is a scam
>>7664443
I'm a chemical engineer and I never learned CAD. They focused on teaching us aspenONE hysys and matlab.
CAD is really just for civil/mech/EE isn't it?
Even the apple math and applied physics people I talk to spend most of their time in maple or matlab, not cad.
>>7664445
How are you gonna design the plant without CAD?
The NYU Langone Medical Center has completed the most extensive face transplant ever, under Dr Eduardo D. Rodriguez.
The receiver of the transplant was a volunteer fire-fighter, Patrick Hardison, who was injured in early Sept 2001 when a burning house roof collapsed on him.
Despite 70 surgeries, he could not return his life to normality.
The donor was David P Rodebaugh, an artist and cycler who died aged 26.
The face and the scalp were transferred, including, for the first time ever, the eyelids and blinking muscles and also for the first time ever, the ears and ear canals.
The hair and beard are growing as normal, and Patrick could blink from the 3rd day of recovery.
Patrick, like all transplant patients, will need to take anti-rejection meds for the rest of his life.

Neat.
He looks tired, though.
The most face-transplantiest face transplant ever.
That's super cool. If I were him I'd be pumped about having a relatively normal face again.

Big improvement.
Wojak is a little faggot. Pepe is big time.
Nice triple dubs.
I'll start:
Prove:
(cos^2(x/2))/(cos(x)+sin^2(x/2)) = 1
>>7664390
This is just your homework.
>>7664390
cos(x) = cos^2(x/2)-sin^2(x/2)
therefore cos^2(x/2)=cos(x)+sin^2(x/2)
this version is better because the equality is also valid when x=pi
>>7664390
do your own homework ass.
What would Einstein think of IQ tests? His ideas of intelligence and genius seems to me a contradiction of IQ.
He'd probably say something along the lines of "They can't measure imagination" or someshit
>>7664359
but isn't it true?
IQ tests can measure conformation, not innovation.
If you look at all the people who made the most amazing discoveries in the natural sciences and math over the years most of them are geniuses but not all of them are polymath super scientists. Take a look at people with IQ's over 200 today like Terence Tao who won gold at IMO at age 13 or whatever. He has not made critical contributions to mathematics but he is clearly one of the brightest technical minds currently on the planet. Lots of what is responsible for innovation is luck, Einstein's image is popular because he was both a technical and innovative genius and he had cool hair and wrinkles.
What is intelligence?
you're mum idiot
Intelligence has been defined in many different ways including one's capacity for logic, abstract thought, understanding, self-awareness, communication, learning, emotional knowledge, memory, planning, creativity and problem solving.
