amazingcarrotsanddasterdlypears asked: Hey. So I was reading through a national geographic magazine and I came across the term M-theory. But they didn't give me any explanation. Can you explain it to me?

In theoretical physics, M-theory is an ultimate theory that mathematically combines the five superstring theories and the supergravity theory in eleven dimensions, as well as the four fundamental interactions.

This is the most accurate summary that I have found about string theory:

So, obviously I can not. For those who don’t have access to the universal doubts fixers (Wikipedia, Google, or your Mom) a friend of mine suggested The Elegant Universe by Brian Greene.

Neuroimaging: Live from inside the cell
A novel imaging technique provides insights into the role of redox signaling and reactive oxygen species in living neurons, in real time. Scientists of the Technische Universität München (TUM) and the Ludwig-Maximilians-Universität München (LMU) have developed a new optical microscopy technique to unravel the role of “oxidative stress” in healthy as well as injured nervous systems. The work is reported in the latest issue of Nature Medicine.

I’ve never been female. But I have been black my whole life. I can perhaps offer some insight from that perspective. There are many similar social issues related to access to equal opportunity that we find in the black community, as well as the community of women in a white male dominate society…

When I look at — throughout my life — I’ve known that I wanted to do astrophysics since I was 9 years old…I got to see how the world around me reacted to my expressions of these ambitions. All I can say is, the fact that I wanted to be a scientist, an astrophysicist was hands down the path of most resistance through the forces of society.

Anytime I expressed this interest, teachers would say, ‘Oh, don’t you wanna be an athlete?’ I want to become someone that was outside of the paradigm of expectations of the people in power. Fortunately, my depth of interest of the universe was so deep and so fuel enriched that everyone of these curve balls that I was thrown, and fences built in front of me, and hills that I had to climb, I just reach for more fuel, and I just kept going.

Now, here I am, one of the most visible scientists in the land, and I wanna look behind me and say, ‘Where are the others who might have been this,’ and they’re not there! …I happened to survive and others did not simply because of forces of society that prevented it at every turn. At every turn.

…My life experience tells me that when you don’t find blacks, when you don’t find women in the sciences, I know that these forces are real, and I had to survive them in order to get where I am today.

So before we start talking about genetic differences, you gotta come up with a system where there’s equal opportunity, then we can have that conversation.

” —

Neil DeGrasse Tyson in response to a question posed by Lawrence Summers, former Treasury Security and Harvard University President

"What’s up with chicks and science?"

Are there genetic differences between men and women, explain why more men are in science.

The Astro Alphabet
By Ethan Siege

A is for Aurora, the Earth’s polar lights,
as the Sun’s hot electrons help color our nights.

B is for Black Hole, a star’s collapsed heart,
if you cross its horizon, you’ll never depart.

C is for Comet, with tails, ice, and dust,
a trip near the Sun makes skywatching a must!

D is for Dark Matter, the great cosmic glue
that holds clusters together, but not me and you!

E is for Eclipse, where the Moon, Earth and Sun
cast light-blocking shadows that can’t be outrun.

F is for Fusion, that powers the stars,
as nuclei join, their released light is ours!

G is for Galaxies, in groups and alone,
house billions of planets with lifeforms unknown.

H is for Hubble, for whom Earth’s no place;
a telescope like this belongs up in space.

I is for Ions, making nebulae glow;
as they find electrons, we capture the show.

J is for Jets, from a galaxy’s core,
if you feed them right, they’ll be active once more!

K is for Kepler, whose great laws of motion
keep planets on course in the great cosmic ocean.

L is for Libration, which makes our Moon rock,
it’s a trick of the orbit; it’s tidally locked!

M is for Meteors, which come in a shower,
if skies are just right, you’ll see hundreds an hour!
