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?
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
