"This adventure is made possible by generations of searchers strictly adherent to a simple set of rules. Test ideas by experiments and observations. Build on those ideas that pass the test. Reject the ones that fail. Follow the evidence wherever it leads, and question everything. Accept these terms, and the cosmos is yours."

❝ For a democracy to function correctly, we need as many citizens as possible to at least have an understanding of the scientific method. ❞

- Brian Cox on why science is essential to modern democracy. Pair with Ray Bradbury on why reading is essential to democracy. (via explore-blog)

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."

❝ Is it political if I tell you that if we burn coal, you’re going to warm the atmosphere? Or is that a statement of fact that you’ve made political? It’s a scientific statement. The fact that there are elements of society that have made it political, that’s a whole other thing. ❞

SpaceX To Test Rocket Landing Legs With Soft Landing At Sea

Today’s SpaceX launch to the International Space Station will be the first to test the deployment of landing legs (seen above) on the rocket’s first stage as it attempts a soft landing at sea. If all goes well this will be a significant step forward in developing reusable-rocket technology that could dramatically reduce the cost of space exploration.

Watch this video of the Falcon 9 Reusable rocket’s first flight test: https://www.youtube.com/watch?v=0UjWqQPWmsY

Most of NASA’s funding goes to out-of-house contractors, such as SpaceX, in the private sector. By advocating for an increase in NASA’s budget you are helping SpaceX reduce the cost of space exploration for all of us. Take action today! Tell Congress to increase NASA’s budget: http://www.penny4nasa.org/take-action/

Richard Feynman ‘The beauty of a flower’


"Some claim that evolution is just a theory, as if it were merely an opinion. The theory of evolution — like the theory of gravity — is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it’s also a soaring spiritual experience."

Get you best paper, cut a circle and fold it, fold it so that the circumference falls on a fixed point inside. Repeat, using random folds. Now see the creases. This is how you paper-fold an ellipse.
