What are you working on ?

Mission progress ?

pic related is what I'm doing. brainlets only, no high iq shitposters needed. some of us are 25+ iqlets brainwashed by pop math into wanting to underachieve intellectually so don't spoil these threads for us

I'm trying to find some data for the IQ of STEM students/graduates. Preferably engineering.

I can only find averages. I want to see all the data.

I saw some data like this while I was at mit, email the stats dept and they will get it to you, probably

Interesting. For what subject? Can you remember some of the outliers (both low and high)? I'm very interested in seeing the outliers. It will greatly satisfy my autism.

Is there any reason why we use rockets instead of airplanes with a liquid oxygen storage to get to space?

Building a SSTO Spaceplane is absurdly difficult and the development costs are more than anyone has cared to pay.
>>
stay tuned my friend :^) NASA basically confirmed the working mechanisms of the EM drive which allows us to travel to Mars in 17 minutes with multi-dimensional wormholes that are fueled by Qualia consciousness gems.

tl dr : Rocket fuel is the most efficient and feasible way to get a fuckton of stuff up to space.
>>
>>7783713
Why not to use airplanes with rocket propulsion? Wouldn't the lift reduce fuel expenses?

We are working with uncertainty principles in my chemistry class and I have no idea how to go about answering this question.

Is there a formula that I can use and can someone point me in the right direction?

The question is:
If photons of green light (wavelength=530 nm) are used to locate the position of the basketball (thrown with a velocity of 30 m/s) with precision of one wavelength of the green light, what would be minimum spread in the speed of the baseball?
>>
You need to use the following equations:

$E = \frac{{hc}}{\lambda }$
$E = m{c^2}$
$p = mv$
$\Delta x\Delta p \geqslant \frac{\hbar }{2}$

Hey, /sci/. I know this may be geared towards /adv/ but I dont want to go to that depressing faggot board. Is this too full of a schedule? I need all these classes to be completed because a Berkeley transfer is planned.
Discrete Math
Differential Eq.
Assembly lang.
Data structures
Calc III
Physics III

I'd appreciate any serious responses. I do go to SDSU where Ive noticed that curriculum is far easier than it should be and Ive gotten straight A's, but these classes could be different. Thanks in advance guys

>is this hard???

I don't know what you're expecting to hear. It definitely depends on you, bro. Are you willing to put in the effort required in these classes?

You can always make it feel softer if you study some of it right now so you get with the intuition in place. Try http://ocw.mit.edu/courses/ocw-scholar/

I just thought I should probably share this with you, I couldn't stop laughing.

Hi /sci/

i need some books or information sources o energy configurations within atoms,like how the electrons move, how you can see what element something is from its light spectrum. and also about the wave/particle duality.

i cant really find anything that i can use online,
and i cant afford to buy any books.
can /ci/ help me?

fuck you guys :(

Here you go, everything you could ever want to know about the behavior of electrons and photons.

$\int {\mathcal{D}\psi \mathcal{D}{A_\mu }} \exp \left( {i\int {{d^4}x\left[ {\bar \psi \left( {i\not D - m} \right)\psi - \frac{1}{4}{F_{\mu \nu }}{F^{\mu \nu }}} \right]} } \right)$

Please explain enantiomers to a retard. I don't get it, and I've read the definitions everywhere - in my textbook, on Wikipedia, and on various chemistry sites.

Mirror image, compare right and left hand.

Happens when a carbon binds four different groups. If two of these groups are swapped, a mirror image is formed.
>>
If you have a chiral carbon (a carbon atom bonded to four unique substituents), placing that compound "infront of a mirror" will give it's enantiomer. Your right hand is the enantiomer of your left hand. A good check for this is that no matter what you do, you cannot get the original connectivity of the enantiomer without breaking bonds.

>In the South Seas there is a cargo cult of people. During the war they saw airplanes land with lots of good materials, and they want the same thing to happen now. So they've arranged to imitate things like runways, to put fires along the sides of the runways, to make a wooden hut for a man to sit in, with two wooden pieces on his head like headphones and bars of bamboo sticking out like antennas—he's the controller—and they wait for the airplanes to land. They're doing everything right. The form is perfect. It looks exactly the way...

Nobody said they are. To the best of their knowledge these are the actions which are required for an event to happen. Rain dances, hunting rituals, animal sacrifice, all early pseudo-scientific attempts at understanding the world. Even the Mayan calendar is pseudo-scientific. The act of counting days between eclipses, full-moons, etc,while it may allow for prediction of future events, does not get into the process of what causes a full moon or an eclipse. But one can say these are essential steps in the evolution of...

Give it to me straight. How many hours of *hard* work do smart people do per week? And by hard work I mean stuff like mathematics / CS / physics / STEM academia (or even programmers outside of academia or smart people in general), which require stuff like mathematical knowledge, creativity, trial and error, the whole deal.

I see varying things. By default people say lots of work. But poincare did 4 hours a day of according to wikipedia. Marx worked from 9 to 7 at the british library and then more at home.

Well, let me tell you about my friend, one of the top 12 british mathmaticians atm

He only works, per se, like 4 hours a day - he goes into work monday to friday, but he mostly answers emails and discusses problems with other mathmaticians.

Thats it.

But the key is what you spend your free time on - my friend has like 20 hours of free time a week, but he does his maths for fun. For him, it is free time, and as a result although he technically only works a few hours a day, he is doing maths effectively every waking moment without pause because its fun for...
