SCIENCE IS SO COOL LIKE

"We are like dwarfs sitting on the shoulders of giants. We see more, and things that are more distant, than they did, not because our sight is superior or because we are taller than they, but because they raise us up, and by their great stature add to ours."

This tumblr's for all the great men and women of science for whom we owe our current understanding of the natural world; their achievements, their failures, and even their quirks, we celebrate them all.

For Science. For Inquiry. For Humanity.

Tupac’s cool (yet creepy) return from the dead to perform at Coachella: Here’s how it was done.

Tupac’s Return … How was it done?

This a great explanation of what was not, in fact, a hologram, but rather an illusion called “Pepper’s Ghost”.

The optical techniques behind this illusion actually date back to the 16th century, developed by camera obscura tweaker Giambattista della Porta. Which I think is important becausethe Machiavelli/Makaveli theory is just too much fun it’s all part of the plan he shall return.

Full explanation at the link, but the Tupac that we see above is a hi-res computer rendering projected onto an invisible sheet of Mylar foil from some point off-stage. No word on if the footage and vocals were an actor or reconstructed from previous performances.

Awesome use of science, all the same.
