Hello /sci/

My adviser and I have been back and forth on pic related twice now--he's convinced that the R2 value should be very high, given that for all values of pKH Equilibrium rejection is about 1. I believe that the low value given by excel is correct, in that it indicates that no matter how high the pKH goes, the final equilibrium rejection will not exceed 1.

Eliminating the outlier gives an R2 of .023, if you were wondering.

Who's right?

That's what machines are for, faggot. Until we get a machine that can write this thesis for me and create original thoughts, it can do my math for me.

>>8607273
In what way? There's no correlation between the independent and the dependent variable, therefore the R2 should be very low, right?

Because it doesn't get interesting until late in the degree when things start to make sense.

>tfw about to fail my optimization course

My lecturer is so fucking garbage it's unbelievable. His lectures are the most boring thing imaginable, he's just standing there awkwardly fidgeting a bit with his hands and talking in himself. Worst of all, the course material is useless. We only have lecture slides (no book, or proper lecture notes), but those are a pain in the ass to learn from, it's an unorganized mess. Other than that we have some HARD AS FUCK practice problems, which are basically impossible to make unless you already have a thorough understanding of the subject.

Now, does anyone have recommendations for me? I have the test this Friday and I want to pass the class. Unfortunately since I'm not American this course is fixed in my curriculum so there is no way I can simply drop the class. Things we have to know include:

ILP modelling, Dual Simplex Method, Branch and Bound algorithm, P vs NP and approximations algorithm.

If anyone can link good lecture notes or recommend me a book with practice problems that would be great.

> If anyone can link good lecture notes or recommend me a book with practice problems that would be great.

There is no such thing. I'll literally curse anyone who posted Stanford's Convex Optimization course.

Optimization is a shit subject. All books are shit.

I assume you're German, because their curriculum has such a hard-on for optimization.

As everything, last minute prep is bound to fail. Prepare yourself mentally.
Best course of action, to make sure you can do all of the HWs and practice problems and past exams.
Ask your classmates, and tutor for help.

>>8606813

I can sympathise with how a lecturer and shit powerpoint lecture slides can make simple things seem horrifically complicated.

Try to find out what textbook your course is based on and look in there.

Excuses. Everyone in your class has the same problem.
The only difference is they didn't whine and actually did the work.
That's why you'll fail and they won't.

What's the science behind uncommonly large breasts?

Is it a natural or artificial selection thing, or just luck of the draw?
25 posts and 2 images submitted.
>>
>>8605937
Men sexually select women with larger breasts because it makes them look fertile and able to provide lots of nourishment to offspring. Obviously there is some genetic variance. Whether you call this selection artificial or natural is a bit iffy philosophically, but that distinction doesn't matter that much in this case.

tl;dr: yes

High levels of estrogen generate very attractive female forms flat stomach, big butt, huge breasts, wasp waist.

So the fact that I hate big breasts and ass just makes me an outlier?

if i answer these questions i could win some free shit, but I'm horrible at math.

1. There are 9 red balls, 8 green balls and 7
blue balls in a box. How many balls do you have to pick up to ensure you have at least 1 ball of each color?

2. There are 10 questions on a test paper. They can be answered with either yes or no. How many test papers are needed so that at least 2 of them have the same combination of answers?

3. What is the volume of a triangular prism measuring 7cm long, 5cm wide and 10cm tall?
The raffle key is the answer of the 3 questions above added together.

then understand the relativistic approach, because it is a relativistic theory. you need to understand the lorentz transformation and the forces and the way to maxwell equations.

This is David Blackwell

probably by most accounts, the greatest black mathematician ever

this is what he said when he met Von Neumann for the first time


"He did a year of post-doctoral studies as a fellow at Institute for Advanced Study in 1941–42.[6] At the Institute, he met John von Neumann and von Neumann asked Blackwell to discuss his Ph.D. thesis with him.[7] Blackwell, who believed that von Neumann was just being polite and not genuinely interested in his work, did not approach him until von Neumann himself asked him again a few months later. According to Blackwell on this meeting, "He (von Neumann) listened to me talk about this rather obscure subject and in ten minutes he knew more about it than I did."[8] He departed when he was prevented from attending lectures or undertaking research at nearby Princeton University, which the IAS has historically collaborated with in research and scholarship activities."
>>
other exploits

on Neumann's ability to instantaneously perform complex operations in his head stunned other mathematicians.[157] As a 6 year old, he could divide two 8-digit numbers in his head.[158] When he was sent at the age of 15 to study advanced calculus under the renowned analyst Gábor Szegő, Szegő was so astounded with the boy's talent in mathematics that he was brought to tears on their first meeting.[24]
