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>

It is the Haber (or Haber-Bosch) process and while its contribution to energy usage and emissions is negligible compared to its benefits, the private sector is always looking for ways to keep things affordable. That means trying to come>
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>
C/2012 S1, Comet ISON, is intriguing because it has never approached the sun before and that is scientifically terrific. Comet ISON began in the Oort cloud almost a light year away and has traveled for over a million years. Unlike more famous comets, Halley's as an example, it has never come this way before >
