Pool shots come down to geometry and momentum. Aim the cue ball at the exact contact point and the object ball flies straight toward the pocket, no luck needed.

She was also the smartest of the main cast but was taking geometry as a junior and was trying to get into Stanford.

It’s not which neurons fire. It’s the geometry of their activity patterns. The piriform cortex doesn’t just store odor “labels.” It continually reshapes that geometry to encode odors.

just worked out the geometry of these activations and they're super weird. they're a linear graph inscribed on a cone with finite volume and infinite surface area.

I'd not come across livegeometry.com before, but livegeometry.com/CatrionaAgg is quite some way to announce it! Definitely going to check it out.

If something's shoved right against the mirror, a bit of geometry from the "reflection world" might poke through. I discovered this by making the debug penguin crouch in front of the mirror.

From the 8th-15th centuries, 600+ years, they dominated the study of math & astronomy. Arabic numerals. The decimal system. Algebra. The astrolabe. Trigonometry. Geometry. 60% of stars we can see with the naked eye have Arabic names. Neil DeGrasse Tyson praises them all the time. Rfk is an idiot.
