#OTD 7 June 1866 Gaston de Chasseloup-Laubat sets the first officially recognized land speed record of 63.159 km/h (39.245 mph) in a Jeantaud electric car.

Adam Savage gets to see the most important science book ever written — the first edition of Sir Isaac Newton's Principia Mathematica printed in 1687! And the original written manuscript.

If I can't hold and touch these objects myself, I'm happy I can at least watch someone who's probably more excited than I am. About 15 minutes of joyful viewing.

Émilie du Châtelet, who hypothesized conservation of energy, established kinetic energy as distinct from momentum and proportional to (speed)², and combined work by Newton and Leibniz with her own original ideas in "Institutions de Physique," was born #OTD in 1706.

Du Châtelet is an important figure in the development of classical physics, but she is not nearly as well known as many of her male contemporaries.

Finally got around to joining, so just a brief #introduction and hello!

I am a #historian, #postdoc, and Associate Director of the Institute of Intellectual History at the University of St Andrews.

My past research has focused on #intellectualhistory (specifically Scottish political thought/theology in the 17th century). I am now working on a new postdoctoral project about #earlymodern Catholic & Reformed student migration, education, and identity formation.

A Dutch East India Company bond, issued to Jacob Van Neck, 1622. Van Neck invested 2,400 guilders and was to be paid back at 6.25% interest over the course of one year. Van Neck was a Dutch ship captain who led a trade expedition to Indonesia in 1599 -- bringing back a million pounds of pepper and cloves -- before retiring to become mayor of Amsterdam.

I have published extensively on late #Medieval England, most recently in #LegalHistory. I have recently moved more into the #EarlyModern period (16th-17thC).

I was always very enthusiastic about open source software and about building public goods on the internet.

Our World in Data is built as a non-profit, all the work we do is licensed under Creative Commons, our software is open source.

So I'm very excited to see how good Mastodon is! Let's all work together to build a great community here on this platform!

Together with a great team I am building the website OurWorldinData.org

Our goal is to make the data on the world's largest problems accessible and understandable.

You also find us here on Mastodon:

This map shows only people. It is a beautiful illustration of where people are concentrated.

If you squint, you can see Australia and New Zealand.
