The furthest known galaxy has been discovered this March
http://www.nasa.gov/feature/goddard/2016/hubble-team-breaks-cosmic-distance-record
It's called GN-z11 and it's 32 billion light-years away. I have a question, if we can now see galaxies that existed just 200 million years after the Big Bang does that mean that soon we will be able to see the Big Bang itself?
We've already seen the Big Bang

I've seen this image so many times can someone explain it to me? I always visualized the Big Bang as a single point?

While I know that no such lens exists in real life and probably never will, as far as I can tell the mere existence of a lens like this would cause entropy to decrease and allow background heat to be turned into useful energy.
Is there something wrong with this, or is two-photon excitation really that magic?
>an hour later
>no attempt at explaining why this doesn't work
/sci/ does realise that this is a power source for a perpetual motion machine, right? I thought someone at least would try and refute it.
>>7922743
Probably something to do with thermodynamics or quantum mechanics or the EM spectrum
one of those seciency things, you know?
>>7922609
You can't double the frequency without actually interacting with the material. The total entropy still rises.
I assume that's what you're suggesting.
Maybe with a ridiculously strong electric field the vacuum itself would become non-linear, but that's a completely different beast.
How exactly does the damage occur in a nuclear / thermonuclear explosion?
I mean, I can see what happens, but how does the fusion or fission of atoms result in that sizzling burn and huge shock wave? Does all the energy exclusively come from the fissile material, or is there some kind of chain reaction with the environment that helps drive the explosion?
And what is the bright, burning "fuel" that appears to make up the explosion's fireball?

how come the plane didn't get hit by an EMP burst?
Is the concept of time a human construct?
Doesn't time require observation?
Time exists, the concept of ticking seconds in just a construct
https://en.m.wikipedia.org/wiki/Spacetime#Spacetime_intervals_in_flat_space
>>7918505
Just remember that time is a result of causality not the other way around
>>7918515
Units of time are defined as seconds.
Further, the entire phenomenon is 'observed' from a reference frame.
If you already know from the existence of mankind that biological life can occur in a planet with the right conditions to a level where those biological entities create civilizations, means of transportation and communication, then does it basically make it impossible to debunk the possibility of the existence of aliens ?
well ? >:o
>>7928828
yeah but it doesn't mean you proved they exist or anything
>>7928828
Ya. No one can actually say alien life is impossible and be able to prove it. In fact that'd be a much more difficult thing to prove than proving aliens do exist.

Why is the area a of the circle of radius r a = pi * r2 ?
because the area of a circle of radius 1 is π
:^)
Just set it as an axiom. Any other response would move the goalpost.
Becouse, pic related. Use transformation [math]x=r \cos(\theta) \wedge y=r \sin(\theta) [/math]

What's the point in studying science if you're never going to be like Einstein?
>>7926997
You could study science to discover what made Einstein's brain special and replicate it in other humans, like yourself.
Einstein was a Jew who worked for the patent office
>>7926997
Bad way of looking at it ~100% of people won't be Einstein, but then Einstein was only able to be Einstein because of Maxwell, who was only able to be Maxwell because of Faraday... The point is the massive paradigm shifts are very rare and when they happen they're built on a foundation of other, solid, research. You're unlikely to be the next Einstein, but you very well might help the next Einstein have his idea, at some point down the line.

If telekinesis was possible, how many laws of physics would that break? 3? 5? 8? 13? 21?
without some kind of telekinesis field this would definitely violate fund theor of thermodynamics
>>7926641
Not really that many to be honest, telekinesis is possible with strong enough em forces

How do you convert seconds to microwave time?
let's say you have 60 seconds that would be 00:60 but if you have 61 seconds then it would be 01:01.
What's the wizardry, /sci/?
>>7926613
If x=seconds
Just do (x/60) for minutes and (x%60) for remainder seconds.
>>7926613
you realize 61 seconds is just 00:61 right?
OP I type in 00:99 all the time just to save button presses. I know that it's the same as 01:39. Why can't you comprehend this?
Yesterday a guy was giving pamphlets that said that the man who discovered ADHD affirmed the inexistence of the disorder.

thats probably because he didnt discover it, and it was already labeled, he just wanted to sell drugs. hysteria has probably had 5 different names in the last century itself

Question 3: Remove All
Implement a function remove_all that takes a Link, and a value, and remove any list node containing that value. You can assume the list already has at least one node containing value and the first element is never removed. Notice that you are not returning anything, so you should mutate the list.
def remove_all(link , value):
"""Remove all the nodes containing value. Assume there exists some
nodes to be removed and the first element is never removed.
>>> l1 = Link(0, Link(2, Link(2,...

I won't make your homework, faggot.
I'm sorry OP, but I only program in assembly via smoke signals, I can't help you there

What's /sci/'s opinion on Math assignments rather then exams. Just finished High school And I fucken hated them. Thoughts?

That isn't a funny joke at all.
What "A+ maths student" would assume that "fraction" meant "fraction involving only rational numbers"?

thats not even right

Is the country where you take your PhD especially relevant?
My former MSc supervisor says Spain PhDs are shit tier, but honestly, I think he might be biased and might have interest in keeping me to apply for a PhD with him in my country. That is pretty much out of the question, since I want to either go abroad, or stay in a R&D position in a company as I am currently.
The situation is as follows: I currently have two pending applications in my field for Spain, one I need to give a yes or no answer pretty soon, and the other awaiting a final response (both of...

Without having any knowledge of the university that awarded it, I tend to put all degrees from EU nations on equal, favorable footing. The same goes for US, Soviet, Canadian, Australian, New Zealand, Japanese and South Korean PhDs. I'm a bit leery of modern Russian, Chinese, and South/Central American degrees, and I discount Indian, African, and Arab degrees almost entirely.
>>7925764
> Japanese, South Korean PhD
I don't know why you think these two are equal to US in PhD because my friends who aren't good enough to get into America apply to them as a sure win backup.
>>7925812
It might just be personal bias on my part, and it also might be due to my field. As an American, I generally deal with chemists that have US PhDs, but I've also met Japanese PhDs that are on par with their American counterparts.
Why hasn't there been a breakthrough in any kind of medicine since the 60's?
Were still using chemo, were still using antibiotics, and the VAST majority of the drugs people use were created in the 80's or earlier
Why can't big pharma push the envelope anymore? Is it because the FDA became too autistic and strict with their double blind trials and strict requirements for drug creation?
Literally when was the last time there was a real breakthrough in medicine? A REAL one. Not "curing AIDS" for the 10,000th time.
because ever since we've been able to isolate disaster-class bio's such as polio, the implications have become too dire. this may seem blunt, but when you think about it, can be applied to every scenario
we would need the ability for a computer to very quickly isolate and contradict any threat to the collective before we allow the power of bio to surpass our ability to understand it
