What’s an attosecond?

As I continue to ponder the mind boggling character of quantum physics (the 10^-n reality), I’m fascinated by articles about novel experiments which routinely explore infinitesimal time scales and distances. Nanoscale (10^-9) is amazing! But now there’s the attosecond. This Space.com article (April 30, 2018), “The ‘Attoclock’ Shows How Fast Electrons Move in a Millionth of a Billionth… Continue reading What’s an attosecond?

Celebrity and cultural phenomenon — Stephen Hawking

Stephen Hawking died last week. Lots of tributes in the media about his scientific legacy and life. Sean Carroll posted an article on his blog on March 16: “Stephen Hawking’s Scientific Legacy.” It’s particularly interesting. As a career physicist and cosmologist, Carroll met and interacted with Hawking over the decades. Early in his career Carroll turned… Continue reading Celebrity and cultural phenomenon — Stephen Hawking

Star bright, first light — fingerprint hunt

Following up on the “Ultimate how” question in the context of the Big Bang theory, how far back in time can we actually detect evidence, follow a breadcrumbs trail? To a cosmic dawn? Space.com, among others, today posted articles about research at the Murchison Radio-Astronomy Observatory (MRO), in particular the MRO’s Experiment to Detect the Global EoR… Continue reading Star bright, first light — fingerprint hunt

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

We’re a story-driven species — 2019 TV series ‘Cosmos’

This Space.com article heralds the coming new season of the “Cosmos” TV series: “‘Cosmos’ Tackles Humanity’s Future: Q&A with Creator Ann Druyan.” Yes, science communicator is a real profession. A new season of the science TV series “Cosmos” [“a show largely about astronomy and astrophysics”] is set to premiere in the spring of 2019, penned by… Continue reading We’re a story-driven species — 2019 TV series ‘Cosmos’

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
