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.
