In somewhat terrifying but hopefully positive personal news, I've decided to purchase an extremely expensive 10x10 booth in the exhibit hall at the American Geophysical Union meeting in December. I'll be selling my gemstone and wire jewelry and art. I hope you'll come find me there.

My name badge is hanging at mid-chest from a chain of beads that look like planets. In the foreground, trays of colorful bracelets. To my right, stands with necklaces. Behind me, a sign with photos of planets says "Emily's Space Craft."

Happy Isotope Day everyone! 🥳On this day in 1913 Nature published Federick Soddy's paper "Intra-atomic Charge" www.nature.com/articles/092... in which he introduced the term "isotope" (coined after a dinner conversation in Glasgow with Margaret Todd the classics scholar). how will you celebrate?🧪⚒️🌊
black and white picture of Federick Soddy looking at the camera. A plaque on a wall in Glasgow celebrating Federick Soddy the text says: At a dinner party held in this house in 1913 Federick Soddy (1877-1956) introduced the concept of "isotopes". He was awarded the Nobel prize in 1921 for his work on radioactivity.  Photo from X account of @is_glasgow

Let’s wrap #EarthScienceWeek ⚒️🧪 with outcrop #7. ~200 km northeast of Toronto, Ontario, somewhere on Highway 118 north of Tory Hill is an outcrop that provided a granite sample that helped pioneer lab methods for determining the age of the Earth *and* led to kids today being a bit smarter. 1/4
A Google Street View scene titled ‘18347 ON-118 Tory Hill, Ontario. The image shows a rough outcrop of fractured rock around 1 metre beside a road. On top of the outcrop is a power pole with several cables and there is a thickly vegetated forest beyond the outcrop.
