How does one determine the ideal population density for a civilization without "environmentalism" hijacking it and saying everyone should live in a prison cell-sized apartment?

You mean like what the hipsters are doing now?
Why not just use capitalism?
If people don't want shitty housing, they won't take it. Let the shitty shipping container houses collapse and have someone that knows what they're doing come in and build actual housing.
>>
>>8559587
Everything that I've read seems to imply quality of life and overall life satisfaction seems to increases as population density decreases. I've never seen any real counter-arguments for why a higher population density would be better aside from stupid shit hipsters would care about.
>>
>>8559609
Quality of life is relative to what people can afford.
Obviously people have a higher quality of life if their homes are bigger and they're friendlier with their neighbors and whatnot.
But not everyone can afford that.
Lots of people simply choose smaller housing because that's what they can afford--society deems that they are only worth that much housing.
Lots of people also choose denser neighborhoods because it's close to work. Imagine having to drive an hour to work every day. There is a correlation between depression and driving time.

not necessarily, it depends on the mechanism of the antibiotic

sometimes antibiotic resistance is as simple as a slight change in the protein conformation of a ribosome so that drugs no longer can block the exit site of the elongating protein

"Evolution" doesn't mean "improvement." There's no such thing as "devolution." A new environmental pressure killing off one kind of bacteria so another will survive, reproduce, and expand to fill the niche in its place is in fact evolution. Just because you consider not having an enzyme somehow "worse" doesn't make it not evolution. Also, it's not "the power of natural selection at work." That's the opposite of natural selection since they're introducing the environmental pressure themselves.

evolution is all around you!
look at bacteria !
>bacteria losing genetic information and not gaining new genes

I am a very confused young man.
I work 40 to 50 hours a week as a manager at a department store.
I have about $6000 saved up (was more but had to pay for my fathers cremation and funeral)
I missed a little over 180 days of school when I was in highschool because I was taking care of my father
I failed 3 classes (due to the fact I didn't do any of my make up work)
I got a 1420 score on my SAT but I forgot to study or bring a calculator or do any preparation before it.
I don't know what to do, I want to study math and get a PhD in it honestly because I enjoy it very much and study it on my own when I can find motivation and time to do so.
Do I retake the SAT and hope for a higher score? I think my GPA in highschool was 2.0 to 2.5
I am currently enrolling to start an associates degree in engineering at a community college cause I figure its hopeless to go to a real university with how much school I missed and all that.
atleast I can take my family out to dinner for christmas and can eat everyday

If I was you then I would just, right now, try to get in a state school. Even to one that has no competition and all. Just do it.

If no one will take you then go to a CC, pass some traditional classes every math major has to take like calc and linear algebra with As so that your GPA gits gud and then apply to state schools again.

Don't let your dreams be memes.

I flew on a training plane and expienced 4g and -0,5 g

Can someone explain this carefullly to me?

Why did I experience these forces just by going down? I mean i dont think the plane was able to accelerate at 36m/s^2

It was a propeller one

>I mean i dont think the plane was able to accelerate at 36m/s^2
That's the centripetal force caused by the wings diverting the air in order to make the plane turn. I do glider flying as a hobby, some planes can handle up to 8g during steep turns.
>>
The fact that the plane is driven by a propeller is irrelevant. Only the wings mater when you "pull Gs" and yes, small aircraft are easily capable of doing these maneuvers.
>>
what type of maneuver brings more gs?

going down

or turning the plane 90º with the ground, then going up

?

I'm trying to confirm that a particular area in my place isn't within a magnetic field of above average strength. I downloaded a tesla meter app for my phone, and it seems accurate in the sense that unlike with the Compass app, when I put my phone near known magnetic fields (like a magnet or transformer) the reading rises dramatically and also bounces up and down a lot.

But I've read from unofficial sources on the internet that smartphones only measure DC fields, not AC fields. Is this true? If so, what's the cheapest way to detect AC fields or both AC/DC magnetic fields?

>>8557558
I assume by "AC fields" you mean alternating magnetic fields. The Alternating Current forms fields that can be measured just as well with a magnetometer (really depends on the frequency though).

If you want to detect an alternating field, you could just use a radio. Most consumer electronic devices are tuned to oscillate in the GigaHertz range, which can be picked up by nearby radio receivers.

It really depends on what exactly you're looking for.

If the scientific method is just one epistemic method out of infinitely many, and science is merely a subset of philosophy, then why do non-scientist philosophers completely evacuate any field that scientists are directly involved with? Surely they have a lot to contribute? Philosophy is more than just science.

So for example, philosophers love talking about the brain and consciousness but they are suspiciously quiet about how cars work. Why is this? Why isn't the Harvard faculty trying to work it out, when cars are such an important part of our society? The engineering / scientific school has merely done it through the scientific method yet there are still so many more methods to be used!

It seems the main function of philosophers is to spin ever more elaborate and unfalsifiable chains of reasoning about subject areas that haven't yet been colonised by scientists or mathematicians and desecrated with maths at a higher than secondary school level. But that's just my ignorant cynicism, no doubt.

Suppose, for a second, we could travel faster than the speed of light.

With this in mind, would there be some other upper limit on how fast we could possibly go? Is there a physical constraint on speed beyond the speed of light?
19 posts and 1 images submitted.
>>
why does it matter?
>>
yeah, there is a constraint, it's called the speed of light
>>
The speed of light really refers to the speed of causality and is a maximum speed having to do with the space and time between two events which are causally connected. The only reason we call this speed "the speed of light" is because it happens to be the speed that light travels in a vacuum. Maxwell's equations reveal that light travels the same speed regardless of inertial reference frame.

In this thread you state your major, state majors you respect (due to difficulty, interest, etc) and give a compliment towards the other majors or fields of study
I'm a chemistry major and I gotta give respect to the few physics majors around in my school. Our physics lab is so low budget but the lectures must get ridiculous towards junior year

My major: Mathematics
Majors I respect: None except my own.

To
Physicists: Great memes. Keep em coming. The internet wouldn't be what it is without you. I wish you a memeful christmas

Chemists: Your memes are shit and much harder to understand but you help make the medicine that cures my asthma, I think. So you know, keep the advances coming. Great jobs.

Engineers: Thank you for not competing for women with me. I am so glad that you are all gay. It really helps because there is already a lot of sexual competition at unis and honestly I couldn't deal with it if I had more opponents. Great jobs

Biologists: Thank you for keeping my ego up. If it weren't for you and physicists then math would be the lowest paid major. Great jobs
>>
>>8556887
My major: Chemical Engineering
Majors I respect: None at an undergrad level

To
Other Engineering disciplines:
Electrical: You do control engineering, but you waste that background because of your limited education in mechanics and chemistry to model physical processes. Electrical circuits and signals are only so useful.
Mechanical: Heat transfer really isn't difficult. Vibrations is just baby wave mechanics.
Civil: At least you guys lift.
Mining/Petro: Stop money whoring

Mathematicians: Some of you are ok, especially those heading into mathematical physics and other applied maths requiring you to be well educated in a variety of fields instead of circlejerking in one small niche most of your career. Good background in your major allows you to access the other STEM disciplines easier. If you were less lazy and included some chemistry, biosciences and more mechanics in your electives most of you would be successful.

Physicists: You're like the amateur version of an engineer, not really worth my time, call me again when you have your PhD on something important. Actually don't call me you filthy labratting codemonkey.

Computer scientists: You autists made some nice libraries for us, you're ok when you aren't fucking ponies.

Chemists: I have yet to see anything you are capable even after postgrad that any of our junior undergrads can't do

"""Engineers""":
Industrial: Back to the business and management faculty
Nano: How do you manage to be even less educated than MSEs?
Physical: Nice job studying watered down physics and not even being accredited fuckhead.

Bio, food and health sciences: If you just included some PDEs and numerical analysis/simulation instead of forcing a dumb degree mill programme you would actually be employable as something more than lab techs.
