Last night, I fell trying to walk to my steps in the dark and I basically hit myself in the brow/forehead in pic related. I don't have a concussion. My pupils weren't looking weird, it was bloody, ran down my nose a bit, but after pressing it down with a soapy wash cloth, it stopped 95% of the bleeding. It was a bit swollen and purple last night, and still today it is a tad swollen and I'll put ice on it now.

three pictures showing the cut

Do I have any cause for concern? Is this one of those deals where you hit your head and get a stroke one year later out of nowhere because of bleeding in your skull or something, or is this just a cut that I can put neosporin on and cover with a bandaid with some ice on it?

I don't have any weird head aches. I don't feel mentally off. I have anxiety over the possibility that something could have been affected, but nothing like memory loss or anything like that.

I'm just paranoid about anything related to head injuries. Am I going to be okay?

I'm a MENSA member, IQ of 154 and I fail in any aspect of life. Total failure. I've never accomplished anything, specialized in anything etc. Just took this stupid test and joined the organization. I like science. Any advises ?

Imagine a square, sitting on a piece of paper and talking to his friend, Ms. Circle. As their universe is infinitely thin, Mr. Square would only see a line segment of Ms. Circle, even though that's not the shape she is. A two dimensional object cannot "see" two dimensions-- only one. Likewise, three dimensional humans cannot actually see three dimensions, only two dimensions at a time.

Here's where it starts to get cool. If Mr. Square was falsely convicted of grand larceny and had to go to Square Penitentiary, we could say "oh, you can easily escape! Just hop vertically out of the square!" Of course, he wouldn't know how to do that. The third dimension is beyond his comprehension of the world.

Likewise, if a human was stuck in a jail cell, there would have to be a fourth dimension we could escape through. There is *mathematically a direction that we simply can't point to because we cannot perceive it.* For all we know, fourth dimensional beings are walking all around us, watching our every move.

Premise: nothing moves faster than the speed of light

Problem: we have observed the opposite

Solution: ad-hocs (space can move faster than the speed of light, particles also move faster than light but only during a small period of time and therefore it doesn't count)

And you are telling me that there is nothing fundamentally wrong with this?

>Specifically, Google and an international team of scientists have successfully simulated the energy surface of a hydrogen atom. If you’re a chemist, you’ve probably bolted up in surprise, but for the rest of us, it’s difficult to properly simulate chemical reactions on a computer, because the different parts of an atom can be in so many different states, called a “superposition.” It can take days to figure out simple reactions, and more complex ones, like drugs reacting in the human body, are more or less impossible.

Oh boys

What if the journals would contain totally no name papers, so there will be no bias in the review?

Then you would need to actually read it, not just trust. Of course, there would be rumours and shit but...

Are you doing science because of "muh dick" of because of "muh progress and shit"?

I've noticed that a lot of my math friends are into music.

I'm taking graduate-level math classes, and I really like to play both classical and jazz flute. In addition to that I listen EDM, rock, indie, and rap, and am well-versed in music theory. My professor and advisor is a graduate of Cornell University, and he plays guitar in a local rock band. Most of my friends on math team play classical violin. One plays jazz trumpet.

Do you think there is some sort of correlation between love of math and love of music? Examples? Why do you think this is?

Pic is my favorite classical flute piece to play.

I have experienced this event twice i will give both examples twice. I am 19 and this has happened twice over 4 years.

first story
>I was a student ambassador in Ireland.(i was 15)
>me and group other students were playing a card game laying in grass under a tree out side our hotel.
>someone tells a funny joke and i go into a hysterical laugh and it starts.

>everything goes white like(see pic related, it was more white wall than tunnel vision) but i can confirm my eyes stay open.
>sounds start to fade and so does my ability to feel, smell, and move.
>Eventually i have lost all of my senses, feel, smell, taste, hearing, sight.
>I have also lost my ability to move
>I can still think to myself
>for a few seconds all i have our my thoughts and whiteness.
>then all my senses fade back in, first being sound then sight and so on.
>The last thing i was able to do was move.

Second event
>i got in a bad car accident.
>we flipped, i hit my head on the dash and hurt my back against the hard racing seats of my friends car.
>I had a concussion but it never got treated and because i didnt realized i had a concussion i took pain relievers.
>two days later i was driving myself and a friend to a concert a hour away.
>I was on the intestate when i started
>my friend told a funny story and i went into a hysterical laughter.
and just like before
>everything goes white like(see pic related) but i can confirm my eyes stay open.
>sounds start to fade and so does my ability to feel, smell, and move.
>Eventually i have lost all of my senses, feel, smell, taste, hearing, sight.
>I have also lost my ability to move
>I can still think to myself
>for a few seconds all i have our my thoughts and whiteness.
>then all my senses fade back in, first being sound then sight and so on.
>The last thing i was able to do was move.

Luckily while i was in my "state" i was able to keep the car relatively straight and we only moved into the other lane a little bit.

Both events lasted roughly 10 seconds.
