As teased earlier this month, today the Event Horizon Telescope (EHT) project announced and presented the first ever photographs of a black hole — “the last photon orbit.” Another epic story of big science and an international team. The interplay of models and simulations, data capture, and complex processing. And funding. Much news coverage. Here’s… Continue reading Photographing a black hole?
Much has been written about Richard Feynman. Many tributes and books. Feynman wrote some books as well. But the inspiration for this post is an exhibit promoted for Caltech’s 82nd Annual Seminar Day and Reunion Weekend May 16 – 19, 2019. The Mind’s Eye: Richard Feynman in Word & ImageIn work and play, Richard Feynman… Continue reading Feynman’s legacy — quantum originality
I’ve written elsewhere about neutrinos (aka “ghost particles”). The latest news is about a particular discovery — a major team effort — as to the source of some of the most energetic ones. Many articles. Some contain illustrations. High-Energy ‘Ghost Particle’ Traced to Distant Galaxy in Astronomy Breakthrough Most of these neutrinos come from the… Continue reading Blazar neutrinos
A lot of science goes into exploring space. Great stories, with lots of people, lots of hard work, lots of challenges, lots of money. Yesterday’s historic launch of SpaceX’s Falcon Heavy is one of those stories which reflect our understanding of the Earth and beyond. A tale of 10^n. It’s an epic moment when we… Continue reading Beyond The Jetsons — SpaceX’s orbital car
So many media headlines today regarding the observation of both light (EM spectrum, not just visible/optical light) and gravitational waves from colliding neutron stars. Lots of visualizations. Big science in action. Here’s a sampling of headlines: Gravitational waves from kilonova collision of neutron stars discovered – The Washington Post Gravitational waves: So many new toys… Continue reading Kilonovas and multi-messenger astrophysics
