Book recommendation for anyone who has ever spent any time in academia as either a teacher or a student. The Saber-Tooth Curriculum is a 1939 sharp-witted critique of the educational system that hasn’t lost an ounce of relevance in the 77 years since its publication. Its pseudonymous author J. Abner Peddiwell describes a society of cavemen who refuse to update their curriculum of fish-grabbing, horse-clubbing, and tiger-scaring long after the environment around them has changed. The book serves as an excellent argument against the fallacious logic often used in the defense of preserving tradition in academia.

It’s not technically science but I’m pretty proud of our creation. Behold, the Periodic Table of Cookies! (Bell peppers for obscuring identifying info.)

I’ve done a reaction with 40 wt. % dimethylamine solution in H2O. The bad thing was that it only started when the solution was at 90 °C and it was slightly exothermic, so after it started, it was at 100 °C in no time.

The gas bubbler at the top of the reflux condenser indicated that a LOT dimethylamine gas escaped from the reaction as seen on the gif. The coloration of the liquid in the bubbler was caused by an indicator to see, that dimethylamine is going away or something else is happening.
