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?

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
