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.

@MsHouseMD Thank you! These ancient traditions are absolutely fascinating to me.

A friend recently brought to my attention that Merriam-Webster defines "yule" only as synonymous with Christmas. Further down the page the etymology and history are briefly given but I'd think the definition could be expanded!

"In 20 years of science reporting I have never seen such pandemonium at a scientific meeting."

Check out the story of the discovery of the Great Attractor in this amazing article written in 1994 by Dennis Overbye for the New York Times: https://web.archive.org/web/20150526105256/https://www.nytimes.com/1994/10/23/books/whither-the-universe-sideways.html

I took this shot of Hollow Rock on Grand Portage and Lake Superior a decade ago.

Despite this spot being only about 45 minutes of my house, I seldom get there. Every year, I think that I should go photograph it in December when the sun comes through the hole, but then I end up doing other locations for the good sunrises.

The water was low a decade ago! You can't get this close now that water levels are near normal.

I logged on here yesterday for the first time in two weeks - thanks so much to everyone who has commented on my photos and sent messages. I hugely appreciate it, and wish I have had more time to engage.

Sorry for the lack of response - things are busy, as I have just moved house, and I'm running photography workshops and working on commissions.

I hope you are all enjoying the wintry weather if you have it! Long may it last

@neuralengine Oh that "scifi news" hashtag (#GalacticOnion) is fun, hope it catches on.
