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>
SpaceX have a striking video showing Mars spinning faster and faster, transforming from the current red Mars to a planet with a small ocean and with the deserts tinged with green in seven revolutions. Of course that is poetic exaggeration - it wouldn't terraform in a week. So how long would it take? Science fiction>
After attracting scorn with bizarre classifications of a weedkiller, bacon, and hot tea, the French statistics group known as the International Agency for Research on Cancer (IARC) decided to puncture claims that activists had manipulated the process by doing a flip-flop on coffee. Though they were widely expected>
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>
Bats generate a measurably distinct aerodynamic footprint to achieve lift and maneuverability, quite unlike birds and contrary to many of the assumptions that aerodynamicists have used to model animal flight, according to University of Southern California aerospace engineer Geoffrey Spedding.
The researcher, together>
A new optical technique by which audio information can be extracted from high-speed video recordings, by using an image-matching process based on vibration from sound waves.
The technique is based on the fact that sound waves are mechanical waves that cause air to vibrate when traveling, the paper notes. That vibration>
