These days I am putting the finishing touches on a hybrid algorithm that optimizes a system (a gamma-ray observatory) by combining reinforcement-learning with gradient descent. Although I published an optimization strategy for that application already, I am going back to it to demonstrate a case where the simultaneous>
Pluto, along with many other dwarf planets in the outer solar system, is often thought of as dark, icy and barren – with a surface temperature of just −230°C. But now a new study, published in Nature Geoscience, suggests that the body has had a warm interior ever since it formed, and may still have a liquid,>
Eighteenth-century socialites have been depicted as vain, silly women who were poisoned by their white lead makeup. The Countess of Coventry, Maria Gunning — a society hostess renowned for her beauty — is said to have refused to stop wearing foundation containing white lead, even as she lay dying. Why would women>
A gravity model of the Earth constructed with data from GRACE. Credit: University of Texas Center for Space Research and NASAIt is all about gravity these days. First came GRACE (Gravity Recovery and Climate Experiment) and then we'll have GOCE (Gravity field and steady-state Ocean Circulation Explorer). I'll reveal>
In 1957, when the USSR launched Sputnik, it began a new era in the Cold War. The Race to Space. Senator Lyndon Johnson worried the commies could rain nuclear bombs down on us from the high ground, making him the perfect guy to run NASA and because it was a military concern it got funded. Only later it>
Like the surface motif of a bubble bath, the spatial distribution of a magnetic field penetrating a superconductor can exhibit an intricate, foam-like structure. Ruslan Prozorov at the U.S. Department of Energy’s Ames Laboratory has observed these mystifying, two-dimensional equilibrium patterns in lead samples>
