What ancient money tells us about the future of computers

The way that some of the first coins were viewed 2500 years ago is similar to how we regard computers today, writes Annalee Newitz

Coloured transmission electron micrograph (TEM) of chloroplasts from the yellow portion of a yellow/green variegated Coleus blumei plant. Chloroplasts are the sites of photosynthesis, the process that synthesises carbohydrates from carbon dioxide and water using sunlight. The structure of a variegated chloroplast is slightly different from that of a normal green chloroplast. The granal stacks, formed from parallel thylakoids (membranes, bright lines), that contain the chlorophyll pigments are less ordered in the variegated chloroplast. The pigments themselves are also slightly different. Magnification: x14,300 when printed at 10cm wide.

Quantum Darwinism: Can evolutionary theory explain objective reality?

Quantum phenomena “wash out” as particles interact with the environment, but classical properties survive. Are they selected in a process analogous to evolution by natural selection?
