Hey guys, any of you land any undergrad research that lead to authorship? How'd you do it?
I ask as a community college kiddo with a subpar GPA who wants to transfer into uni as a junior, and to make up for my shitty earlier years with some a solid portfolio so grad school at a decent place isn't impossible.
Just ask around with the professors. I'm coming from a small private uni so the chance to do research is a much greater privilege (profs usually do an informal application process) but if you are at a larger uni there should be someone who will take you.
Tip: ask everyone if your first few choices aren't responding. You want to tell grad schools you did research for X number of years. What it's in doesn't matter that much unless
You are looking at top ten schools.
t. A 3.4 gpa biochem major who did computational research for 2 years and is now going to a pretty good UC for inorganic materials research.
It's very doable.
>>8030724
Damn, biochem and computation is exactly what I want to get into. Kind of eerie, lol.
Thanks for the response. I'll be going to a state uni, so pretty big, hopefully someone will take me. My only concern is not having enough time to establish contacts and just having to immediately pester staff for a spot - is that acceptable? I was considering sending out applications for research before I even transfer, so that when I arrive I'd, ideally, be researching from day one to make up for two years at a junior college with nothing special.
I proved that the use of nCr always results in a prime if you factor out the denominator from the numerator. But there are rules and its basically counting so it never got published.
Let [math]T[/math] be an operator on Hilbert space [math]H[/math]. Let [math]A \in H[/math] and [math]\chi_A[/math] its characteristic function.
What does [math]\chi_A(T)[/math] mean?
>>8029827
for x in H
xhi_A (T)(x) = :
1 if T(x) is in A
0 otherwise.
>>8029835
Unfortunately no.
Here is a context btw
With your assumption, the dimension doesn't match
>>8029841
then don't call chi a fucking characteristic function if it's not one. It's a projector.
Why do we need to sleep?
Is it because our brain doesn't have lymph nodes?
>>8028820
Regeneration, memory management, make you use much less energy and resources when you don't really need then, prevents you from going out of the cave out of boredom to get eaten by predators.
>>8028820
No one knows for sure
>>8028820
I don't know but it's some fucking bullshit. It seriously angers me how much of my life I have to spend sleeping. Every scientist who's working on extending people's natural lifespan should instead focus on eliminating the need for sleep, it'd extend the amount of time we have available to do stuff in our lives by decades.
who goes to Queen's for engineering?
I go to King's. I love guys, I love you.
hnnng
fuck queens, western all the way
Nice pole.
is evolutionary psychology a valid approch to human behaviour ?
>>8046947
Yes.
Anyone who disagrees is clearly retarded.
>>8046947
>psychology
>valid
choose one
>>8046950
You were just conditioned to think that way due to your environment, your opinion is too limited in scope and invalid.
When did you realize that engineering is insane?
>>8046207
The worst part is the pay isn't even that great. True cuck work.
This is why engineering is the intelligent choice.
>>8046221
>4-7 IQ points
this is like saying you're better than someone because you're .5" taller than they are.
4chan is a superintelligence. Opinions?
More like a superstupidity, IMO.
>>8047392
Superintelligence, if intelligence is horse shit to you.
>>8047406
Mentally retarded superintelligence maybe, or immature.
Is climate change real?
yes. it was sunny yesterday and its raining today
I got a sunburn yesterday.
Honestly, we have a climate crisis.
No. Planck function is a lie.
Are visual proofs mathematical proofs?
>>8043036
Yep
>>8043036
it depends
>>8043036
no. never.
visual drawings give a good idea of things, but unless you actually write it down, it's really easy to trick yourself
>there are people out there who think this is genuinely a good idea.
I sure am glad that my doctor has to consult her textbook everytime I visit; aren't you, guys?
>>8048019
if the civil engineer designing my septic system didn't have a book open and check all his work with a computer, I'd be pretty upset
this is the same meme as teachers telling you "no calculators on this exam, you won't be carrying a calculator with you everywhere you go in life!" when literally 100% of people have a wolfram-alpha capable pocket computer with them 24/7 the following year
next decade it'll be "don't take this test using your sub-dermal brain implants, anon, that's not going to be useful in real life!"
>>8048019
>tumblr
Just don't visit that shithole nigga
>>8048019
>I sure am glad that my doctor has to consult her textbook everytime I visit; aren't you, guys?
I sure would be glad if the last 4 times I've been to a doctor, they could have found what was wrong with me instead of just giving me a retarded prescription for symptoms that would come back later. If they need books to help me, let them use books. They're trained to do that.
At least one had the honesty of saying "I don't know what this is, I won't charge you if you don't want to stay"
In case of emergency, it would be different though. But experience makes for it (just like when you're not looking at your fucking keyboard everytime you type)
It's good for engineers/people who decide to have orders of magnitude in mind when talking. No one sounds more retarded than a guy who asks why we don't make a dyson sphere or why we don't build cities in the middle of the ocean.
Anyway the issue OP has is an issue for undergrads who are worried about exams.
The man who knew infinity?
>>8036582
Certain people are born in this world but not apart of it. These people are like Ramanujan, Gauss Cantor, Godel etc.
>>8036630
Were they aliens?
>>8036630
agreed and langan
What's the best way to get red pilled on evolution? I want to be able to understand it and know the evidence instead of just trusting the scientists and knowing nothing about the subject.
>>8043876
>red pilled
ugh
Anyway, I don't know, you could take just search for open courseware in biology that covers evolution, natural selection etc...
Watch more dawkins
>>8043876
darwins origin of species probably best place to start
>Proved the Poincaré conjecture
>Refused the Fields medal and the $1 million Clay Millennium Prize

I cannot even begin to imagine how nihilistic and apathetic he must be with his high IQ.
>>8039280
Sounds like he is mentally ill.
Grigori Perelman is ugly though. If he is ugly then how could his Mathematics be right? Just because it says Geometry or "Topology"? I don't think he is even Poincaré conjecture. Perhaps he is a Muslim. He recently moved to Israel as I saw in the documentary about him.
The Rhind Papyrus is an ancient Egyptian mathematical papyrus which dates from about 1650 BC. This is around the time of ancient Egypt's middle kingdom (a bit later, it seems). The papyrus contains some (very) elementary problems of arithmetic and geometry - in particular, quantities are reckoned (somewhat arbitrarily!) in terms of /Egyptian fractions/, which are sums of unit fractions (fractions whose numerator is one):
https://en.wikipedia.org/wiki/Egyptian_fraction
In the mid-19th century one Alexander Rhind, a Scottish antiquarian, purchased the papyrus in a shady deal; this is where the texts' namesake comes from. Mr. Rhind died a few years later, and so the papyrus came to be in the possession of the British Museum, where it lives today.
I went to the library and I have an English edition (Chace) of the papyrus close at hand, so I'm going to go over it and post about it in this thread. It will be a very, very simple mathematical recreation, which yet has some historical interest, and then I can say I've been through a meme text. If you find this thread boring, you're welcome to hide it, but as we'll see, it has a perfect right to be on this board.
Comparison with my library book shows that this OP picture is problems 45-60, or thereabouts.
>>8027713
Very cool, I'll be following this thread.
>>8027713
Me too, sounds pretty cool. Pretty, pretty, pretty cool.
Unfortunately the Egyptians' attitude towards math was purely utilitarian. They did not contemplate theoretical stuff, but only sought methods to perform calculations directly connected to real life problems like measuring areas of polygon shapes etc.
Rocket thread! Talk about space (mainly rockets and the iss with space programs) and share images!
I got a question, what it the original space shuttle program worked?
ITT: Pic related
>>8040690
How many old Space Shuttle boosters are left?
What is more efficient in terms of pure delta v, Nerva engines or ion propulsion?
Does the ion propulsion change much if its powered by a nuclear drive instead of solar cells?
taking this into account, does anyone have any sources regarding what propulsion is being considered for the mars mission?
i mean, surely if we could get around the nuclear paranoia the nervas would be the best bet for it
