"I wished to establish some sort of system of simple bodies in which their distribution is not guided by chance, as might be thought instinctively, but by some sort of definite & exact principle." -Dmitri Mendeleev (born #OnThisDay 1834) on the origins of the #PeriodicTable

There's something poetic about promoting a podcast that examines Katharine Burr Blodgett's scientific accomplishments on Irving Langmuir's birthday.
(No kidding...Langmuir was born #OnThisDay in 1881!)

In our new building, we are honouring scientists by naming meeting rooms after them. This is room: “Mary Elliott Hill”,
She was (on the first African American Women to achieve that) an organic and analytical chemist and taught at Kentucky State University in the 50’s.

Going through old tweets is reminding me of old blog posts, so figured I would reshare a few. Every wondered why we call the positions on a cyclohexane ring 'axial' and 'equatorial'? Wonder no more #Chemsky #HistChem #HistSci! 👇
