Beyond The Jetsons — SpaceX’s orbital car

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

Biggest thing in the universe?

So, on the 10^n scale, today Space.com posed the interesting question “What Is the Biggest Thing in the Universe?” Scientists have created the first map of a colossal supercluster of galaxies known as Laniakea, the home of Earth’s Milky Way galaxy and many other. This computer simulation, a still from a Nature journal video, depicts… Continue reading Biggest thing in the universe?

Beyond the Milky Way — a game-changing discovery

As I’ve noted elsewhere (Beyond the infinity of black holes), it wasn’t long ago — maybe a 100 years or so, that our view of the cosmos was much more circumscribed. Those who studied cosmology — physicists, astronomers, et al, viewed our cosmos in a much different way, at a much different scale — basically… Continue reading Beyond the Milky Way — a game-changing discovery

Communicating what physics says — The Science Asylum

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 — The Science Asylum

Astrophysics is what?

Wiki’s definition of astrophysics is comprehensive. Contemporary astrophysics often is associated with Big Science programs involving both observational and theoretical work by large, interdisciplinary teams. Astrophysics is the branch of astronomy that employs the principles of physics and chemistry “to ascertain the nature of the heavenly bodies, rather than their positions or motions in space.”… Continue reading Astrophysics is what?

Quantum spin — angular what?

I’ve been reading about quantum spin for awhile and taking notes. Hobson’s book1, for example, discusses the foundational experiment which discovered spin. In the mean time, Space.com posted an article today which may serve as a placeholder for the topic while my draft notes on other topics develop. The Space.com article “The Weird Quantum Property… Continue reading Quantum spin — angular what?

Kilonovas and multi-messenger astrophysics

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
