Citizen science in the age of connectedness
A nice column in the New York Times by biologist Aaron E. Hirsh explains the rise of Big Science massive, centralized projects with large staffs and expensive equipment and the emerging trend of distributed citizen science. [more]

"Physics is to the rest of science what machine tools are to engineering. A corollary is that science places power in our hands which can be used for good or ill. Technology has been abused in this way throughout the ages from gunpowder to atomic bombs."
- John Pendry, Imperial College London
