Communicating what physics says — Domain of Science YouTube channel

Today’s post is somewhat different than usual. I’m highlighting a YouTube channel. Communicating science to a general audience has a long history. The bibliography for my physics blog contains some books by authors to this purpose. Modern physics has many great stories, and the just plain strangeness of quantum physics lends itself to great storytelling.… Continue reading Communicating what physics says — Domain of Science YouTube channel

Blazar neutrinos

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

More about entropy — reality vibrates

I studied thermodynamics as an undergrad. Online resources really help refresh my understanding; so, here’s a summary of my notes about entropy. Hopefully these agree with how the term is used in physics. Statements Equation:  S = k ln Ω [Wiki] “The second law of thermodynamics states that an isolated system’s entropy never decreases. Such… Continue reading More about entropy — reality vibrates
