"There are two great mysteries that overshadow all other mysteries in science. One is the origin of the universe. That’s my day job. However, there is also the other great mystery of inner space. And that is what sits on your shoulders, which believe it or not, is the most complex object in the known universe. But the brain only uses 20 watts of power. It would require a nuclear power plant to energise a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that’s a compliment."

This is why Google is awesome
10 years ago this month, Google placed this anonymous billboard on Highway 101 in the heart of Silicon Valley.  Once you figured out the answer and entered in the correct URL, you were taken to a page directing you to the next level of testing.  In case you’re wondering what the first 10-digit prime found in consecutive digits of e is, the answer can be found here.

trigonometry-is-my-bitch:

How a hole is drilled to be made square, the red shape in the center would be the cutting tool.
it shares the same principle as a Reuleaux triangle but with one rounded corner so that the cut square does not have rounded edges; the cutting tool follows the path of the rounded edge that is tangent to the sides of the outer square. because a tangent line is perpendicular to the radius, as the cutting tool follows the path of the rounded edge it turns precisely 90° to create a sharp edged perfect square.

A series of Animated GIFs excerpted from Journey to the Center of a Triangle (1977): another fabulous film by the Cornwells, created on the Tektronics 4051 Graphics Terminal. Presents a series of animated constructions that determine the center of a variety of triangles, including such centers as circumcenter, incenter, centroid and orthocenter. More on the Cornwells at http://www.afana.org/cornwell.htm

According to son Eric Cornwell, here’s how the film was made: The 4051 produced only black and green vector images, not even grey scale. The film’s scenes were divided into layers in the programming, one layer for each of the colors in the scene, and each was shot separately onto high-contrast fine-grained b&w film stock. The final scene in “Journey” had 5 layers: one for each of the four colored dots, plus one for the white triangle and line. 

These five clips were then multiple-exposed onto color film on an optical printer, using colored filters to add the desired color to each black&white layer as it was copied. The resulting color was much better than a film of an RGB display would have been because the color filters on the optical printer allowed access to the full range of the color negative film, allowing much more saturated colors. All of that color is pretty much lost now, between prints fading and/or transfers to the VHS, and then viewing them on a computer screen which has a much more limited color gamut. Please imagine it all in bright, brilliant colors. (from Internet Archive)

how to get the d

  • image

i think i don’t want it anymore

as a math person i will give the D to any girl that can solve this. 

as a girl ‘math person’ i will tell you that you can’t solve this as there are no x or y values as it is only a formula and not a question plus we wouldn’t want the d from you anyway

I’ve never seen someone so efficiently shut down in my entire fucking life

as another ‘math person’… it’s really not that hard to solve (with the x and y values of course), just Pythagoras…
