"The Scale of the Universe," created by Cary Huang and ported to Pixi.js by Matthew Martori. Pick your preferred language and use the scroll bar to move from "Planck Length" to the entire "Observable Universe" - 62 orders of magnitude. You move at your own pace and can stop at objects on the various levels to explore them. Brilliant!

Creating matter from light - "Out Of Pure Light, Physicists Create Particles Of Matter," University of Rochester press release, via Science Daily, 18 September 1997
"Generating matter and antimatter from the vacuum," press release from the University of Michigan (via PhysOrg.com, 8 December 2010): "...scientists and engineers have developed new equations that show how a high-energy electron beam combined with an intense laser pulse could rip apart a vacuum into its fundamental matter and antimatter components, and set off a cascade of events that generates additional pairs of particles and antiparticles. 'We can now calculate how, from a single electron, several hundred particles can be produced...'"
"Becoming" by Jan van Ijken - time lapse microphotography and video of a newt developing from a single cell to a complete individual ready to hatch.

"An Ancient Greek Computer" -- article from Scientific American (1959) by Derek J. de Solla Price (one of my teachers at Yale).
"Counterfactual Computation" by Graeme Mitchison and Richard Jozsa, Proceedings of the Royal Society, London, A457 (2001) pages 1175-1194: "Counterfactual computation is a process by which the result of the computation may be learnt without actually running the computer..."
Fukt -- a Berlin- and Oslo-based magazine that focuses on contemporary drawing. It's edited by Björn Hegardt and designed by Ariane Spanier. Published once a year.
Notebook -- a very unusual site, created by Holly Larner, apparently as a personal reference-tool. The internal linking is haphazard, so it's hard to know exactly what's there. But what makes this site worth visiting anyway are the long, uncommon and diverse texts - entire books in some cases, e.g. How to Care for Works of Art on Paper by Francis Dolloff and Roy Perkinson; part of John Ruskin's The Elements of Drawing (1857); etc.
a node for Jack Burnham -- my attempt to provide access to the writing and ideas of this great theorist.
"'Exact uncertainty' brought to quantum world," by Eugenie Samuel, New Scientist, 27 April 2002: "...The result is an expression that looks like Heisenberg's original relation, but gives the exact uncertainty in the measurements of position and momentum. [Michael] Hall says it is an equation rather than an inequality, which is 'a far stronger relation'. So strong, in fact, that in a paper published this month in Journal of Physics A, Hall and Marcel Reginatto of the Physical-Technical Institute in Braunschweig, Germany, have managed to derive the basics of quantum mechanics from it, including the Schrödinger equation that describes the behaviour of quantum-mechanical wave functions..."
"The origin of life and the hidden role of quantum criticality," The Physics arXiv Blog at Medium.com, 6 March 2015: "most biomolecules are quantum critical conductors; their electronic properties are precisely tuned to the transition point between a metal and an insulator... These findings suggest an entirely new and universal mechanism of conductance in biology very different from the one used in electrical circuits..."
"The Known Universe" - a zoom from the Himalayas out to the edge of the known universe and back again, created by the American Museum of Natural History and the Rubin Museum of Art.
"Somebody's Listening" -- by Duncan Campbell, with links to more texts about Echelon and other governmental systems for intercepting private communications.
