Bohr Model: A Delightful History [CC]
How did 27-yr-old Niels Bohr make a model of the atom that was so audacious even Einstein admitted it he did not dare publish them? This is a story of dorky physics jokes, a truly supportive marriage, a useful conversation and a brilliant maid. Ready? Let's…

Super-elastic alloy is first known metal to get springier as it heats up
City University of Hong Kong researchers have accidentally discovered a first-of-its-kind alloy that retains its stiffness instead of softening as the temperature rises. Indeed, high-entropy Elinvar appears to get stiffer and springier as temperatures approach 1,000 K (727°C, 1,341 °F). No other known metals have been found to behave this way.
In addition to the Elinvar effect, this metal also displays an elastic limit of about 2 percent at room temperature. You can see the extraordinary spring-back power of this high-entropy Elinvar alloy demonstrated in a room-temperature ball bearing drop test in the video.

Dispersion correction (D3, D4, VV10 etc) is crucial to get accurate results in quantum chemistry calculations.
Anonymous Quiz
47%
False: It depends on the system size and the correction only gets relevant with ~ 50 or more atoms.
53%
True: every system is subjected to dispersion. Even small molecules with less than 10 atoms.
