What's so special about this?
>>8254507
comes from the e^ix = cosx + isinx case where x = pi
links e, i, pi and contains 0 and 1 (sinpi= 0)
i can't think of any practical applications, but it is a pretty equation
>>8254507
Should use [math]\tau[/math] obviously.
>>8254507
You have to appreciate that you got an exponential to be a negative number without a negative base.
If 1 billion people, all each flip a coin 100 times, what are the chances that at least 1 of them will get heads on every single flip? Also say how you got your answer.

Hey STEMfags. How do you handle the ethical dilemmas you face in your careers? Have you ever turned down a job over ethical qualms? Or do you just go where the money is and not ask questions?
Am an EE major, and all of my most reliable career connections are with DoD contractors. Not sure how I feel about that.
>>8251876
I work at Raytheon. The only ethical dilemma I've encountered is making sure we do our work as efficiently and effectively as possible since we are ultimately funded by the tax payer (of course the government bullshit is basically the opposite of efficiency).

Morality is a spook
>>8251876
I don't. If there is an ethical concern, society as a whole needs to dictate that. From my day to day perspective, it makes no difference to me. I will do whatever the laws and regulations say, and I will be on equal ground to my competitors.
For instance, I work at a petrochemical facility, but my electricity is 100% wind power.

Sadly not the case.
Can man-made acceleration cause gravitational time dilation?
With energy?
Maybe?
Of course.
Acceleration and gravitation are interchangeable.
>>8242920
Acceleration and gravity are the same thing, so yes.

What difference does it made if it's manmade or not ? Are you not gonna stop a meteor crash because it's not a manmade threat ?

>What difference does it made if it's manmade or not ?
Why should I let my own country be punished with carbon taxes if it's not man-made?
I'm not sure if this it the best place for this question, as there isn't a general board for education.
What would be the straightest, purely scholastic route to scoring admission to HYPSM, that is, purely through the performance in school? Not through having extracurricular activities or achievements, but through performance in grades and tests.
Here's my plan: try to teach the child as soon as possible to self-learn by grade six, (either through homeschool), and then homeschool him and spread out virtually every non-language AP exam among his middle school and high school years. After the sixth or seventh grade, he would do nothing but learn how to score fives on these exams and only learn for this purpose, not actually taking the course itself, which will considerably shorten the workload. The structure of the curriculum will be that by the time universities are accepting applications for Early Decision, the AP results for the 12th grade year will be received.
In addition, the same level of dedication will be applied to scoring in the 99th percentile of the SAT and ACT, with frequent practice tests and taking the exam in an official setting as often as possible.
Perhaps I've underestimated the requirements for being accepted into HYPSM. If so, what else could be done in a purely scholastic setting, and assuming the child gets 20+ fives in AP exams and scores in the 99th percentile of the ACT and SAT exams, what's the most prestigious university that would most likely accept him?

Sounds like a fun way of making your kid hate you.
>>8253502
Raise your kid to be a hard-working, conscious, upstanding citizen.
>>8253519
Okay, let me rephrase the question: suppose I wanted to get into HYPSM only through scholasticism, (because I was autistic or something or hated every activity that wasn't directly related to schoolwork). Would this get me into HYPSM. If not, how far would it get me, and what else could I do in a scholastic setting to improve my chances?
Would this plane be able to take off?
No, the plane wouldn't be moving through the air at all, the one thing you need to do for the wings to generate lift
Yeah, planes don't take off because of wheels, they take off because of their wings
Of course it would, that's what the propeler is for, to pull enough wind to generate lift off.

When did you realise that apparently perplexing philosophical problems were a bunch of fluff?
For example:
>Something rather than nothing
We have no reason to believe that 'nothing' exists; it has never been observed.
What other ridiculous concepts are you aware of?
>>8246044
dark matter and black holes are probably made of the same material.
>>8246064
Well, dark matter is just the name given to perceived matter that doesn't interact with light.
Black holes have been indirectly observed, so unless you can come up with a better model they're legit.
>>8246064
No Dark Matter DOES INTERACT
No Black Holes SUCK

Many watch guys say that they're into mechanical watches for the engineering marvel. Exactly how impressive are mechanical watches?
>>8243294
The watch in that picture goes for something like $300,000. It couldn't POSSIBLY be because of how impressive it is from an engineering standpoint, right? Discounting the brand name, the precious metals, all of that. How impressive is the technology behind a mechanical watch like this?
>>8243294
Isn't every watch an engineering marvel?
>>8243336
I mean more of how impressive it all is. That's really what I'm asking. The watch in the OP, the back there, it looks very intricate. I'm wondering if that costs a lot and is part of the price or why people are so interested in them, or if it's 100% a brand thing.
I'm looking for a good, thorough, textbook on neuroscience. Something more focused on the low level. eg, voltage dependent calcium channels, pyramidal cells encoding their outputs, feedback loops and rate limiters for neurotransmitter synthesis, etc. Something a bit more functional than a more anatomically oriented perspective.
I'm aware of the stickied link, but would like some more firsthand opinions.

Theoretical Neuroscience: Computational and Mathematical Modeling of Neural Systems
>>8244414
I'll look into this, thanks. From the sound of some of the reviews it might be close to what I'm looking for. Something that doesn't dick around and try to hold your hand, creating an unnecessary metaphorical and abstraction overhead.
It's a machine. Material that clearly lays out what we think it is, what we think it does, and how, seems rare. Greater meaning is then rendered implicit.

Yesterday, I went to get a head CT scan. This is the only CT scan I've ever gotten. Should I worry about dying of a brain tumor later in life?
Little known fact; The cancer that shows up in your CT scan results are the results of the cancer caused by the CT scan itself ;)
cancers are small people just like you and me,so to detect them in your brain,the doctors must give you a cancer amplifier so the tomography can be done right.But if you dont already have it,you might just get one,go and scan yourself tomorow,who knows what you might find
>>8230508
I legitimately have death anxiety from this. I keep thinking that I shouldn't have gotten it and now I'll die of a fucking brain tumor.
They said the machine was only one year old, so maybe it was very new and optimized and used even less radiation than normal? Also, the actual scan took like 5-10 seconds.
Has mankind developed materials that will allow for vacuum airships to be feasible?
