Scientists from MIT Developed a Trillion frames per second slow motion camera that can show light moving through a bottle. Ramesh Raskar presents femto-photography - For comparison, the imaging of a bullet captured at this many frames per second would last a year as explained in thepresentation by Professor Ramesh Raskar of MIT.
^ what you have witnessed above is light travelling in slow motion.
Math is Beautiful, math is the absolute truth and that makes it beautiful. Mathematicians even go so far as calling it an art form.
mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show - Bertrand Russel
One of the most amazing equations, in my opinion, is the Lorentz factor,
Virtually all of the mathematics behind Einsteins theory or special relativity can be reduced back to this one, simple equation. basically, these few lines describe exactly what happens when you travel close to the speed of light, and the fact that it is as simple and short as it is, is beautiful.
NASA engineers use origami as inspiration when they fold up solar panels for their trip to space. Shown here: the Miura fold. Once a piece of paper (or solar array) is all folded up, it can be completely unfolded in one smooth motion. You can read more about origami in space here, and learn how to do the Miura fold in this video:

This animation from Moonwalk One shows all the stages of the Apollo 11 mission, which launched 45 years ago on July 16, 1969. As designed, the only component to return to Earth was the Command Module Columbia.

I felt so angry at the UCSB massacre (an article about this incident and a script of his video’s speech) and the sexism we’re blind to everyday so I drew about my opinions on sexism to channel my rage.
I’m very happy the #YesAllWomen tag is going strong on U.S. Twitter right now. :D
- willfully ignorant
- It’s not hard to fathom why so many men tend to assume they are great and that what they have to say is more legitimate. It starts in childhood and never ends. Parents interrupt girls twice as often and hold them to stricter politeness norms. Teachers engage boys, who correctly see disruptive speech as a marker of dominant masculinity, more often and more dynamically than girls.
- For example, male doctors invariably interrupt patients when they speak, especially female patients but patients rarely interrupt doctors in return. Unless the doctor is a woman. When that is the case, she interrupts far less and is herself interrupted more.
- This is also true of senior managers in the workplace. Male bosses are not frequently talked over or stopped by those working for them, especially if they are women; however, female bosses are routinely interrupted by their male subordinates.
- As adults, women’s speech is granted less authority. We aren’t thought of as able critics or as funny.
- Men speak more, more often, and longer than women in mixed groups (classrooms, boardrooms, legislative bodies, expert media commentary and, for obvious reasons religious institutions.)
- Indeed, in male-dominated problem solving groups including boards, committees, and legislatures, men speak 75% more than women, with negative effects on decisions reached. That’s why, as researchers summed up, “Having a seat at the table is not the same as having a voice.”
- Even in movies and television, male actors engage in more disruptive speech and garner twice as much speaking and screen time as their female peers.
- Listserve topics introduced by men have a much higher rate of response.
- On Twitter, people retweet men two times as often as women.
The best part though is that we are socialized to think women talk more. Listener bias results in most people thinking that women are hogging the floor when men are actually dominating. Linguists have concluded that much of what is popularly understood about women and men being from different planets, verbally, confuses “women’s language” with “powerless language.”
This preference for what men have to say, supported by men and women both, is a variant on “mansplaining.” The word came out of an article by writer Rebecca Solnit, who explained that the tendency some men have to grant their own speech greater import than a perfectly competent woman’s is not a universal male trait, but the “intersection between overconfidence and cluelessness where some portion of that gender gets stuck.” Solnit’s tipping point experience really did take the cake. She was talking to a man at a cocktail party when he asked her what she did. She replied that she wrote books, and she described her most recent one, River of Shadows: Eadweard Muybridge and the Technological Wild West.The man interrupted her soon after she said the word Muybridge and asked, “And have you heard about the very important Muybridge book that came out this year?” He then waxed on, based on his reading of a review of the book, not even the book itself, until finally a friend said, “That’s her book.” He ignored that friend (also a woman) and she had to say it more than three times before “he went ashen” and walked away. If you are not a woman, ask any woman you know what this is like, because it is not fun and happens to all of us.
Last week as I sat in a cafe, a man in his 60′s stopped to ask me what I was writing. I told him, a book about gender and media and he said, “I went to a conference where someone talked about that a few years ago. I read a paper about it a few years ago. Did you know that car manufacturers use slightly denigrating images of women to sell cars? I’d be happy to help you.” After I suggested, smiling cheerily, that the images were beyond denigrating and definitively injurious to women’s dignity, free speech, and parity in culture he drifted off
In the wake of Larry Summers’ “women can’t do math” controversy several years ago, scientist Ben Barres wrote publicly about his experiences, first as a woman and later in life, as a male. As a female student at MIT, Barbara Barres was told by a professor after solving a particularly difficult math problem, “Your boyfriend must have solved it for you.” When several years after, as Ben Barres, he gave a well-received scientific speech, he overhead a member of the audience say, “His work is much better than his sister’s.” Most notably, he concluded that one of the major benefits of being male was that he could now “even complete a whole sentence without being interrupted by a man.”
“Stop interrupting me.”
“I just said that.”
“No explanation needed.”
This machine allows anyone to work for minimum wage for as long as they like. Turning the crank on the side releases one penny every 4.97 seconds, for a total of $7.25 per hour. This corresponds to minimum wage for a person in New York. This piece is brilliant on multiple levels, particularly as social commentary. Without a doubt, most people who started operating the machine for fun would quickly grow disheartened and stop when realizing just how little they’re earning by turning this mindless crank. A person would then conceivably realize that this is what nearly two million people in the United States do every day…at much harder jobs than turning a crank. This turns the piece into a simple, yet effective argument for raising the minimum wage.
