Updated @Tesla Robotaxi geofence sizes (in square miles):
• Austin: 272
• Houston: 254 (916% increase today)
• Dallas: 81
• Miami: 31
• Orlando: 26
• Tampa: 24
All these areas are fully autonomous/unsupervised robotaxis only.

Elon just said Raptor 4 will deliver 300 tons of thrust at sea level, and hopefully at about the same mass as Raptor 3.
That's on top of Raptor 3 already beating NASA's RS-25, with 34% more thrust at 57% less weight and over 3x the thrust-to-weight ratio, per @XFreeze.
More thrust without more weight is exactly what Starship needs. How far can SpaceX push this?

How big did Tesla Robotaxi just go in Houston? The new geofence is live, and it even looks like a rocket now!
The old zone was a small pocket in northwest Houston.
The new map runs from up near Cypress all the way through downtown Houston, past Bellaire and nearly to Pasadena.

At 250 km/h the air pushes a 2026 F1 car down harder than it weighs. In theory, it could drive on the ceiling. So I built one you can flip.

It was a bit stormy on this morning's walk here in Glastonbury. Rain showers and very very windy.

Mechanics evolved not by adding more forces, but by discovering that nature prefers the path of stationary action.
That shift from causal forces to variational principles opened the road to relativity, statistical mechanics, and quantum theory. The equations of motion stayed, but the language that generates them became deeper and more universal.
What began as a search for the causes of motion ended as a recognition that motion itself is the unfolding of an extremal principle.

Geometry starts with lines and circles, then unfolds into perfect solids and infinite fractals.
Compass constructions yield triangles, squares, pentagons, and the five Platonic solids. Recursive rules produce the Pythagorean tree and Apollonian gasket, each step adding detail without breaking the underlying order.
In these diagrams, simple rules reveal the deep structure of form.
