This semester, I formalized reading assignments on the work of science in my classical mechanics course.
I've called them 'Exercise 0' and they focus on labor, capital, and transparency.
Here's the first six: dannycaballero.info/phy321msu/ad...

Chemist and physicist Ida Noddack was born 130 years ago today. In 1925 she and her husband co-discovered Rhenium, and her 1934 paper criticizing some results of Fermi anticipated the theory of nuclear fission.

Hey #physicsSky, question from an 11-year old that I'm too tired to answer:
Where do photons go? Like, they bounce off of stuff and some hit our eyes and do something and that's sight, but what about photons that don't reflect off of a dark blanket or don't get all the way into a cave or dark place?

The I-field breaks T-symmetry via the dissipation term γu^μ∂_μI in the field equation:
□I + m²I + λI³ + γu^μ∂_μI = -g_I J
This is fundamental irreversibility—not emergent, not statistical!

Okay, now I want to know EXACTLY what velocity a hoagie/italian/sub-sandwich must achieve to pierce Kevlar.
I mean, my physics is weak, but such a velocity must (at least theoretically) exist, right?
Would 4,000 ft/second, for example, cut the mustard?
More?
