Philanthropic efforts on behalf of basic research span a range of modalities, from assistance for individual investigators to the establishment of research institutes.
The combined effects of ozone, sunlight, and atmospheric waves turn the near void of Earth’s mesosphere into a refrigerator capable of producing vast clouds of water ice.
How stars are born from clouds of gas is a rich physics problem whose solution will inform our understanding of not just stars but also planets, galaxies, and the universe itself.
An unusually broad set of experiences helped prepare Stanford Ovshinsky to recognize a phenomenon that forever changed solid-state physics.
Old Sun-like stars observed by the Kepler Space Telescope spin faster than astronomers expected. Apparently, they experience a dramatic shift in their rotation and magnetism at about middle age.
