But that's not even difficult.
We DON'T use the integral in quantum; not for anything that's quantized, at least. Literally the first quantum mechanics was defined by the use of non-integrals (Rayleigh and Jeans fucked this up and used the integral, and got the wrong answer, Planck said "no integrals" and got the right answer).
The second part, while valid, doesn't violate anything; again, nobody is assuming that's continuous. It violates nothing. This is 2nd year stuff.

I hope you guys aren't ACTUALLY all just freshmen in engineering... Right?

Well if it's a 3d shape with any thickness then it is the area that's getting unbounded but the volume stays bounded.
Still the whole joke there is that he meant painting with a brush or something and wasn't aware of that strange physical property of liquids that they are able to flow into all the nooks and crannies of objects.
Which brings me to the last point: paint molecules are not infinitely small so at some iteration they'd stop getting into the smaller holes of the figure. I don't think we even need to go beyond the realm of possibility there, since paint molecules are pretty huge and we can make structures that are pretty small. But I guess I'm getting into the realm of philosophy there since the ultimate question is "what's the definition of painted"

2s complement still holds parity. Taking unsigned is unnecessary.

>>8545527
Is this implying that writing proofs involves having a lot of wrong turns, or that proofs usually have a lot of unnecessary bullshit but it's the only way that it's been solved for now?

>>8545610
Mathematicians usually just publish right after they find a proof, and don't bother spending time trying to reduce it and really understand what's going on. Proving something is only halfway to understanding why it'd true

>>8545650

I thought it states that mathemiticians take years and a lot of "thinking bridges" to get a proof done but then just release a reduced and compact version which doesn't help with understanding it at all.

>>8544788
In the US, pseudoephedrine was a key ingredient in cough syrups. It's also a convenient precursor to making methamphetamine, which is illegal. People making meth would buy lots of cough syrup to extract the psuedoephedrine for making meth. Because of this, cough syrup with pseudoephedrine is really hard to get now. Lot's of cough syrups use much less effective replacements, and ones that do still have pseudoephedrine have to be dispensed directly by a pharmacist. The paper proposes using (plentiful black market) methamphetamine and reversing the usual synthesis to get pseudoephedrine.

tl;dr, it's lampooning the War on Drugs.

>>8545610
>>8545713
This is sort of it. More what it's referencing is that the both the collective and individual efforts to prove something generally go all over the place in every direction with many false leads and dead ends (and beneficial tangents too) before something is found that works.

In the case of the Poincare conjecture (theorem) that the comic is talking about, the final proof ended up relying on Ricci-Hamilton flow as the "correct" tool but it's not as though that was the first or even the hundredth thing somebody tried applying to the Poincare conjecture

A mathematician would just take an infinite number of chairs and reduce his falling speed incrementally.

A physicist is visiting Los Angeles. As he takes photos from the top of a skyscraper and helpfully points out the position of a couple of amateur aeronatus to them upon request, the fire alarms sound. Trapped atop the building, his only chance of surviving is to jump from the building into a tiny swimming pool several stories below him. He quickly pulls out a few slips of paper and a pen, and frantically scribbles on them. Then he stands up, takes a deep breath, jumps and flies off into orbit. What happened?

Well, this is easy. All you need to do is buy a 10-mile radius plot of land in a desert along with a private plane ride for a year later at that location. You will escape the bears and gain a fortune in their dead corpses.

[eqn]i^i={(e^{\ln(i)})}^i=e^{i\ln(i)}=e^{i{\frac{i\pi}{2}}}=e^{-\frac{\pi}{2}}=\frac{1}{\sqrt{e^\pi}} \approx 0.20787957635[/eqn]

Bruh that's a one liner. You just use mod.

return num%2==0? true:false;

>>8552212
do you have to worry about which branch of ln you take when you substitute ln(i) for ipi/2?

I haven't taken complex in a long time but I remember my russian prof always busting our balls over branches of Log, deriving 1/2 = 1/5 and shit like that from equations that looked fine (like yours.)

No. It prints out "The number is even." for every even number from 2 to 2147483647 (1073741823 times) and then after that prints "The number is false."

Parentheses and parenthesis are both used to designate either a pair of the symbols or a single symbol. Is there an accepted alternative? I'm genuinely curious.

My gen chem prof literally said that nature was one of the most prestigious chemistry publishers in the west, and that it's very difficult to get your research on there. What is this horseshit?

>>8538549
I interpret this as sci-fi wherein a lonely girl is dating an expensive android, but the story is told from the perspective of the machine. The machine's actions aren't highlighted, but rather, its thoughts are. Its cold, analytical thoughts.

Misread.

Also, general statements are usually meant to be taken as statistical tendencies and not actually how all instances behave in all conditions.

Even if the specific energy levels are quantized, the integral is still important when considering the probabilistic distributions of electrons in a three-dimensional space, which is what he was asking about. It's more a question of statistics than of quantum mechanics as a whole.

Also, I've long been convinced that this board is full of insecure undergrads. I came here a lot as an undergrad and wound up learning something new every now and then just by lurking the board.

I think a good estimate of the actual expertise of these discussions would be around the level of people with associate's degrees in physics/pre-engineering, above community college but below university-level. For topics beyond that, actual discussion seems to slow down significantly.

>>8552277
>not just return num%2==0;

>>8553600
No, he is right.

Science and Nature are top tier publications. Focus is a little wider than most other publications in that they want things a little more flashy/astounding/illustrated bordering on tabloid, yet still scientifically top notch.

Also articles in one field is meant to be mostly readable to scientists ion other fields, the purpose being to not lose track of the overall picture in science in general.

So yes, getting an article there hard. Getting a front page article requires also a very nice and colourful diagram or figure.

>>8542731
This guy is right:

Modulo is not sure to be optimized for base 2. Worst case the CPU is assigned to do integer divisions which are both super slow in instructions and also clog up CPU pipelines.

The fast way is to do:

return (num & 0x1);

>>8553857
The really skilled people get tired of that, go get a comfy cottage and do their own science in isolation from all the stupid fancy pants air-castle building and patting-each-others-back in publishing.

>>8553875
There's a fair share of skilled people burning themselves out trying to reach those air castles too, my friend.

>>8553879

Yeah. I'm not skilled enough to do that stuff so I'm doomed to try and steer and whip the ones who have the potential. Quite fun. I can act out my frustrations of being a failure myself.

>Burnout
Yup, I saw a lot of it, had my share of near fatal accidents and I got out and into industry. Thankfully only a few of the accidents left permanent damage.

It is when you risk incineration in your lab that burnout doesn't seem so bad.

Correct. Saying that the object isn't properly painted because the paint molecules don't fit into the smaller infinite spaces, is similar to saying that nothing is truly painted because of the electromagnetic repulsion of all atoms.
