Each color is described by the brand as “holographic” because microprisms in the formula shrink and expand to produce the different shades.

In a famous paper, ‘Are ideas getting harder to find?’, Nicholas Bloom and collaborators found that research productivity has been falling quite dramatically since the 1970s. Their data suggests that it now takes 18 times as many resources as it did then to work out how to double the number of transistors on a microchip.

"Today, 85 percent of adults say they spent more time outside when they were kids than children do today."

Census tracts are tiny, hyper-local designations, with populations between 1,200 and 8,000 each; mine is only 0.2 square miles in area.
