Guys I've graduated from medicine but I have a possibility to get a degree from engineering too, should I go for it or just forget I ever started there. Anyone else with a dual-degree from engineering and medicine? Is there any career use for both.

What if the universe wasn't created by energy

How come that if you rub literal shit into an open wound it will most likely get infected, but people with hemorrhoids get shit mixed with blood all the time and it rarely gets infected?

Is the medfag meme true or is it just /sci/ insecurity? You would think that the MD or MBChB would be rigorous and of a high quality given the prestige and strict entry requirements. Does the medfag meme also then apply to Vet Med or any bioscience?

If I were to fire a bullet from outer space at earth, would it increase or decrease in velocity?

Not that much of an epiphany but even so: when I was taught group actions on sets and in particular (the so called) Burnside's lemma I felt I did not undestand it. It took me a little while to figure out something like the action groupoid, and drawing few sets of points with loops around them made me visualize and realize that the actions of groups are very strongly structured. Next thing I knew I was in love with the concept, and I tried (without success) to develop baby group theory (for example, first iso theorem) in that language. I hoped to get isomorphisms of groups instead of bijections but I failed, and even trying with actions of groups on groups was unsuccessful.
Another one was me trying to generalize the lifting of curves (and boxes) along covering maps, I was not so successful (I was getting to CW-complexes without knowing what they were) as I learned after a short while the general criterion. The existence of the universal cover was something strange until I decided to consider S^1, then it became clear.
Most of attempts like those revealed to be dead ends, but it was fun and I learned something. Sometimes instead it was successful, for example giving an analytic proof (of a lemma) instead of a geometric argument, the latter being not so rigorous or correct. I feel good when I finally gather the courage to attempt another proof, or follow a proof on easy examples. But this is something everybody does (right?), not so worth of a clap.

Is it theoretically possible for an organism to feed off sound?

where do child prodigies come from? i'm talking about the 6 year old kids who can speak four languages and play symphonies on the piano and hold physics degrees. are they born a certain way? do they have a compulsion to pursue stuff that autistically or do their parents make them do it? if a hyper intelligent toddler is made and not born then why are they one in a million?

Should I study Physical Therapy or Nursing?

Okay fellas, here's my theory. Please correct any logical gaps you see.

Consciousness, as we know it, is singular. You see through your eyes. Why is that? Why weren't you born 500 years ago, or even born now? Consciousness is literally just atoms moving around.

That's it. There's no "soul", no god, just random groupings of atoms in the scope of our universe. Our existence is completely based on luck.

When you die, that's it. Lights out. But, after that, what happens? I believe that "you", in the vaguest sense of the word, become a new organism. "You" inhabit a different brain and "you" are in the driving seat. My "evidence", I guess, is that we are existing in the first place. People created the image of god because they didn't want to think the universe and existence was meaningless. They grabbed at straws for a single reason for existing.

I do not believe in the Hindu reincarnation. I just believe that since we are each inhabiting a brain via consciousness, it will repeat itself.

If you find this completely retarded, feel free to point out why.

Moral is relative
Ethic is objective
As far as I'm concerned, that's kind of a rule

Heard energy can't be created or destroyed, only transformed
but isn't gravity a source of infinite energy? it continuously gives kinetic energy to things by accelerating them
Where is the catch?

Does this thread constitute evidence of absence or absence of evidence for intelligent life on Earth?

just wondering and i cant find anything answering this online, but is the average of the left and right Riemann sums the exact area under a given curve?

i tested it with the function y = x with 10 partitions from 1 to 3 and the average = 4, which is the exact area.

is this uniform throughout all functions or just this one?

>have a study session for intro E& M

What the fuck is this? Is this how Asians do school? Why the fuck would you do this? This seems like a terrible way to learn.

Are young people secretly conditioning themselves away from ideal women shown on TV and magazines?

Hypothetically, if we could copy the data from all the atoms in your body and print them out again, effectively making a clone, which one would be the real you?

wait a second...

Can anyone link me good physics lectures on YouTube or any other site? My professor is utter shite at explaining anything. Inb4 "outside the class learning." fuck off

What, in your opinion, is the absolute best physics textbook?

>in Biology class
>ask how groups separated for many 10's of thousands of years are perfectly equal when they evolved in varying environments and underwent differing selective pressures
>thought police arrive and shoot me in the face

Prove that the universe wasn't created upon your conception. How can you trust anything that happened before your birth?

I kind of get it now after doing some reading. (you know i only read mathsisfun.com best site xdddd)

I don't get the vectors part though. Each element represents a component. Does three components mean a vector in a 3D coordinate system/space? why duh colum be duh vectur and what duh tensur mean mang halp moar
