Let’s celebrate #WorldBicycleDay!
#Trains are bikes’ best friends😊,and in combination with walking, they compose the smart urban mobility triptych, with reduced congestion costs.

When the Death Star destroyed Alderaan, would it have experienced a kick-back from its laser shot?
Absolutely!
Really? Light can cause a kick-back?
It sure can! If you wonder how much—buckle up for a new cute physics thread!

Our paper on hyperfine resolved spectroscopy of MgF has just been published online in @JChemPhys. We show why it matters to do precise spectroscopy of laser cooling candidates! @fhi_mpg_de

@stevain I mainly use them in combination with some Wigner-Eckhart-Theorem-magic and there, they make sense to me. The only book that I found useful so far is Zare's "Angular Momentum"
Feature: The Stern–Gerlach experiment at 100. In 1922, Stern & Gerlach showed that silver atoms have a quantized magnetic moment, as predicted from the Bohr–Sommerfeld atomic model. But the correct interpretation of the result proved to be revolutionary.
