Is anyone else here really excited for the implementation of this project? I know that this telescope will be significantly more capable than the Hubble, but what sort of things, exactly, will that improved capability allow the Webbscope to discover?

Without using meme, incommensurable numbers like [math]\pi[/math] or other irrationals, or approximations to irrationals.

What's the formula for finding the area of a real circle, i.e. a circle that can exist IRL?

The smallest possible discernible event has no duration. It has happened or it has not. These events are either in the past of the future. There is no constant state of all moments. The sequence of events happen in an order. The state of the world triggers the next events, and the next state the following events. Time is the constant flow of indivisible events. The past is gone. Time is not relative. Time can pass even if we don't witness it. Traveling in the speed of light stops the picture we see of outside events, it does not stop the events themselves. It is all a misunderstanding. Time can not be broken.

I've spent the last decade with wireless headphones on my ears and blasting music when working on something. It came to a point where I don't start working on things unless I start up some music.

is it possible for you to be a good scientist without being a virgin?(its not)
16 posts and 4 images submitted.

>>8796863
Half-right.

I am fairly intelligent, I have an 'above average' IQ and Asperger's syndrome, normally this would a wonderful combination for STEM and I should be thinking about going to do either a master's degree or doctorate by now (I'm 21, going on 22).

However, at 19 I was 'luckily' enough to have caught the attention of someone who apparently didn't notice I had Asperger's and took my 'decent' looks (apparently) as an invitation to baby-trap me.

This forced me to drop out of higher education and has delayed me applying for a bachelor's degree until now.

So, I would say, to a certain extent, that being a virgin (and certainly being caught pregnant) retards your progress in academia and certainly within STEM, as it is a naturally more complex metatopic.

I think you need to know how to live for yourself, focus on seeing the world in a lens apart from social bullshit, and focused on life, the nature of your world, and yourself, long enough to think correctly and be properly functional. After that point it's probably not markedly deleterious, in a core sense, to pursue or accept romantic or sexual involvement.

This always baffled me. What does the proof for e^(ipi) = -1 even look like?
>>
>>8796837
Write e^ix as an infinite series.
Then realize that that series is equivalent to the infinite series of cos(x) and isin(x) summed.

You end up with e^ix = cos(x) + isin(x)

Then plug in pi.

Hey, /sci/entists, I was wondering whether there is strong, conclusive evidence of sex hormones on the growth of feet. Throughout history and over various cultures small-footed females have been considered as sexually attractive. Today high heels tend to give this illusion, foot-binding has been practised in China and Persia, and men from Iran, Brazil,Tanzania, and Papua New Guinea rate small feet as more attractive than large feet. It would appear obvious, then, that estrogens inhibit bone growth of the feet, but finding information of this type has not worked out. It seems that studies on the sexuality of feet are awfully lacking.

If you could provide good studies on this subject or any rational discourse, it would be much appreciated.

Woah really makes you think

>>8793567
So I've been marathoning a certain podcast, and they had an episode about heels a while back. More about design (and a lil history) of heels than why we find them attractive.

If you're interested.

>>
>>8793567
Estrogen doesn't specifically limit the growth of feet. Feet are designed to be a mixture of lightweight and balanced producing. Evolutionarily, it would be more of a physical detriment to have large feet because it would take more energy to lift them and more focus to burst away from a gray timber wolf.

We actually had a civil discussion last time /sci/

Well do you think we are truly alone in the universe or are the odds in favor of some other species all alone out there in space

Let's assume there's life on Pluto we'd have no way of knowing if they were trying to reach us until we were on planet

Do you think Earth would befit from first contact?

Meh this has been done to death...

YES "Aliens" are likely to exist elsewehere in the universe because it's fucking huge

NO we will never make contact with these "Aliens" because everything is really far away and we haven't invented warp drives

NO they won't be little green men, but more likely just bacteria and germs. They won't be intelligent like humans because it took billions of years for us to evolve from bacteria, and we will only inhabit Earth for a small fraction of this
>>
No, there isn't life out there besides us.
There is literally no precedent for it. Until we find life anywhere else, we just have to accept the most likely scenario and the only scenario that there is any actual evidence for, and that is that Earth is the only place with life.

>>8793149
Theres probably other life in the milky way, theres probably older life in parts of the unigerse that cooled before our part of the universe, theres probably not extremely technologically advanced life elsewhere in the milky way, perhaps there is a handful of sentient, intelligent life per galaxy, but it would take tens of thousands to millions of years to contact another one of these lifeforms.

Why do governments put fluoride into the water supply if we get enough fluoride from toothpaste? Is it necessary? Also, how are they complete sure it's safe? Scientists have been wrong before (saying sodium and fats are bad for you). Why should we be forced to drink this stuff when most other advanced nations DON'T put fluoride into their water supply?

The fluoride addition was an attempt to bolster dental health among populus

The actual fluoride itself is water soluble and in such a low concentration that toxicology evidence is non existent. You'll pass out any extra fluoride that remains assuming you even drink that much water. There isn't any evidence that fluoride in the water at the <1ppm level is harmful in anyway

And sodium and fats in excessive amounts is bad for your health. Enjoy neuropathy and heart disease
