Let's just name all those space probes we sent out to explicitely analyise other planets and moons for forms of life.

Uuhhhh.

>>7649030
to counter this, if non life can produce life then surely one of the other earth like planets would have evolved an intelligent form of life capable of receiving our communication signals. the way a habitable planet forms isn't unique to earth and thus there must be billions of earth like planets out there -- and none of them can communicate with us.

>hen surely one of the other earth like planets would have evolved an intelligent form of life capable of receiving our communication signals.

It only has been very recently that we were able to detect other planets at all, nevermind those with actual possible living conditions. Then there is the thing that just because a planet can sustain life, it doesn't mean it can sustain very complex life. And thirdly, even if has been listening to all those different exoplanets for the past 100 years, that's still a tiny fraction in terms of civilisation.

We humans weren't even capable of receiving any possible signal until the 1950s maybe, and life has been existing for almost 4 billion years here. There is just a tiny tiny tiny window of a tiny tiny fraction of other stars' signals we have been able to observe now, and not only has the transmission of singals be made properly (which is a story for itself) , their window of 'sophisticated civilisation' has to match other window time shifted by the distance thir signals need to get here.

Owning a mirror

Can either be strictly psychological, strictly physiological, or both.

I'd wager it's usually a bit of both. Antidepressants should be an absolute last resort, but unfortunately GPs (and to a lesser extent, psychiatrists) give em out like candy. Further solidifying their place in our great "if X then Y" culture.

> how hard is it to get a in research once you've got your PhD?
It's trivial. You've already been collaborating with some people in your field by then, and the whole point of doing a PhD is to prepare you to do research independently. You'll have friends in your field or similar enough fields, you'll be invited to conferences to meet people, and so on.

Most people carry on with some aspect of their PhD work that they didn't get to do while they were finishing their thesis. Typically, you'll have a dozen or so ideas floating around, and you will never get to them all because you'll constantly have new ones.

I should actually say that most people try to carry on with their research in this way. Typically, once you start teaching, it takes a couple years to get settled in and really start doing research again.

> Is there anything I should know?
It's very hard to get a full time, tenure-track job these days. Be prepared to move around a lot, do more work for less pay than the established professors, and develop strong feelings of bitterness about the whole broken system.

On the one hand, you'll end up working 60 hour weeks if you want to get your research in. But on the other hand, you're going to get a bunch of time off. One of my friends has himself down to two days of classes a week, and he marks and does his administrative crap on the day between. Four day weekends, every weekend.

Isn't that more of an American issue?

Why is everyone in a Math PhD autistic?

At this point I'm going to get a B despite a firm grasp on the material.

Methuselah was over 900

Yes, the Bible has many reports of such people.

Almost certainly not. If living to 122 is 1/7 billion now WITH modern medicine, it would be an even smaller likelihood in the past, and since there weren't 7 billion people living in all of past history combined, there's basically no chance.

> What environmental factors contribute to intelligence?

I truly believe intelligence partly comes from genetics, partly from social environment and the amount of challenges you had to go through.

Okay.

Also, if you were one of the older students in your academic year, you obviously have more time to develop and will get a higher score by virtue of that.

This is the most significant, can't argue with that.

The 4 are important but I would still go for B

When I was in middle school one gym teacher told me that if I didn't cool down, my heart would explode and I would die. I believed him for years, and that scared the shit out of me.

>warm up and stretch
You do realize that these two are completely different things right? You should NEVER stretch before exercise.

In any case this thread belongs on /fit/.

>>7659120
I'm sorry if I'm too ignorant on this topic, but why should we never stretch before exercise?

It's harder I'm pretty much addicted to CAD, math, programming, electronics but it's exhausting on my mind, think working out , people are addicted to working out going a couple of hours everyday because it takes a huge toll on your body , the addiction pretty much lies in the daily consistency.

Genetics.

Not even shitposting. There's a higher reward payoff/work for people who are more academically inclined, and academic performance is largely due to your genetic phenotype.

>>7659002
>everything is genetics
Almost everything that people think is "genetics" is actually environment or at most a combination of both. Take a person out of a culture in which he would normally be expected to have poor academic performance and put him in an environment that would encourage high academic performance and guess what happens? It has very little to do with genetics.

None of that image makes sense.
If this were the case, then the object would travel in a straight path because the "centrifugal" and centripetal force terms would cancel, and "path of inertia" is absolutely retarded. Inertia is not a vector.
Centrifugal force is real when you construct the system in a non-rectilinear coordinate system. Not otherwise.

It's as real as gravity.

>>7658575
>Centrifugal force is real when you construct the system in a non-rectilinear coordinate system. Not otherwise.

can you explain that please?

I was always told that centrifugal force is not real and is only a misconception caused by a lack of centripetal force.

as in there is no force pulling the ball outward, there is only the centripetal force and the path of inertia, the ball flying away form you if you let go is the inertia without centripetal force acting on it any more

Atherosclerotic plaques are a telltale sign of heart disease. To image them, LDL NPs coupled with gadolinium ions can be used.

They are not intuitively, they are empirical.

Omg dude you don't understand them? How stupid are you?

I independently discovered them on my own when I was only 6. Shits basic anon.

No but really don't feel dumb just cause you find something hard to understand that doesn't mean anything. Dumb people are people like the guy in that relativity thread who think an idea must be wrong just because they don't understand it.

Certainly you can understand them to some extent... it's just a matter of putting in the time. IQ means way less than being willing to sit down and concentrate, day after day.

How much you get out of it will vary. I have a master's degree and have worked with them for years, and I don't understand them fully, all the implications and so on. The world is really complicated.
