Go Phillies! Way to support LA in the quest to have your wild card series go the full 3 games! Also please win tomorrow as well, even though I’m more scared of your pitchers because I don’t want to have to listen to the Tomahawk Chop ever.

Wanted the Phillies to win just because I’ve hated the Braves since I was a kid thanks to Ted Turner pushing them on us. But White Sox won so that’s good.

For other runners out there, how do you react to dogs along the route? I go in the road to leave them the max space. Ever since I ran close to a seemingly friendly dog that seemed friendly and then just snapped at me and I jumped just clear enough that it only tore a big hole in my shorts.

This is shocking to hear! Einstein kept a picture of Maxwell on his office wall and admired him more than any other scientist. Every fall I teach a whole course about his work. This is like hearing that Westminster Abbey might be purchased so a new car rental place can built on Newton’s grave.

This stuff is cool. The two large craters on Mars (~100m) which were also detected by InSight’s seismometer were amazing. I want to catch these on the Moon. Imagery, lunar impact flash, and seismic detection combined could better define the seismic efficiency factor and the physics of impacts.

Andalusite “Chiastolite”, was a very popular stone among 16th-century religious pilgrims traveling through Spain due to its unique appearance. And the stones, although not holy, are certainly mineral miracles. #MinCup26 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology #geosky #GIS 🍎 🪐 🔭 🌋

Given how many places I’ve lived, I’m not surprised it didn’t get where I’m from (Indiana). At this point, though, I’ve lived in California about as long as I lived in the Midwest, so I guess it makes some sense. Florida also got a little red patch somehow, but New Jersey didn’t stick.

Ontario Lacus is a hydrocarbon lake near the south pole of Saturn’s moon Titan. Measuring 235 kilometers long by 75 kilometers across, Ontario Lacus is slightly smaller than its terrestrial counterpart, Lake Ontario. Lakes on Titan are named after lakes on Earth that are roughly the same size.
