Spring is a popular time to visit Colonial Williamsburg, not least because it’s “lambing season,” the time of year when baby lambs are born and take their first steps (which is obviously very, very cute). But small as they are, these lambs have a big baaa-ckstory (sorry) – they are part of a breed that was once guarded like a trade secret, was smuggled into the American colonies, went extinct in the US in the early 20th century, and then was brought back right here at Colonial Williamsburg. This episode was produced in partnership with Visit Williamsburg.

This is an animated 3D visualization of the growth of Paris from 300 BCE to the present day. It was made with Blender (no AI) by Christian Ivan, who notes that it’s a “simplification” and so might not be 100% accurate. To my eye, the broad strokes are all there. The subtle sound design helps with the overall effect as well.
OpenAI:
With this launch, ChatGPT now offers three subscription tiers globally:
- ChatGPT Go at $8 USD/month
- ChatGPT Plus at $20 USD/month
- ChatGPT Pro at $200 USD/month
And perhaps the bigger news:
We plan to begin testing ads in the free tier and ChatGPT Go in the US soon. Ads support our commitment to making AI accessible to everyone by helping us keep ChatGPT available at free and affordable price points.
Their pricing page has a comparison chart showing the differences in their four consumer tiers (free, Go, Plus, Pro). Screenshot, for posterity. The big difference that will keep me on the $20/month Plus plan for now is that the Go plan doesn’t have access to the Thinking model.
The rate at which the universe is expanding differs depending on how it’s measured. Gravitationally lensed supernovas could solve the discrepancy; the lensing allows for the tracking of the supernovas over time.
