Today, on October 23rd between 6:02am and 6:02pm, we celebrate Mole Day!

On this day, we marvel at Avogadro's Number, 6.02 X 10^23, which allows chemists to count a large number of atoms simply by weighing the substance on a regular scale.

Every chemist has a lab story. Here's where yours can start. 🧪

The MIT course "Laboratory Chemistry" covers principles and applications of chemical laboratory techniques, such as chromatography and spectroscopy. This is an absolute must for anyone who plans to take or teach a chemistry lab course. https://t.co/VrbrGZkg7x

We just learned of the passing of MIT mathematician and programmer Margaret Hamilton. Her work at MIT's Instrumentation Lab was essential to the success of NASA's Apollo missions in the 1960s. She was a true trailblazer. Rest in peace. 🚀
