I'm looking for a couple of upper-level good math students interested in computational thinking, to contribute as Beta Learners. See: youtube.com/playlist?list=…

LJ, be careful to avoid "ex post facto" description of what D.M. saw outside her door. Saying "she came face to face with the murderer" mixes up what she experienced at the time with what only became known later on.

"VW BUG" What is fraction of area in the headlights and hood?

9 circles, 3 radii. Fraction of Area inside yellow circles? Yesterday's posting gave a bum steer. Correct info: The blue circle radius > 2.0 * yellow circle radius. The tangent lines intersect as shown at a point on the outer circle. Only one yellow size packs 'em exactly.

HINT (for 9 circles, 3 radii): I lack the smarts to see an analytical solution, so I used a Dynamic Geometry Environment (DGE) to solve it computationally & graphically. There is only one unknown (radius_blue / radius_yellow), so start with a good guess, model it, then iterate.

Here's the way I solved "9 Circles, 3 Radii" using algorithmic geometry (spread across 3 tweets)

Here's the way you might solve "9 Circles, 3 Radii" using a DGE tool (spread across 3 tweets)

A simple solution to regulate AI thehill.com/opinion/techno… A Public Frauds civil torts law (with rapid-response Court processes) is the best solution. Why? Juries in an adversarial due process are our official finders-of-fact, and rarely err. Public Frauds law is tech-neutral.

Congrats on the Report. Did you consider law that assigns ownership of personal info to the individual, ownership not allowed to be sold, only limited-divulged -purpose usage-rights sold? Please consider how that legal principle could work to shift power back to individuals.

#CuomoTownHall Mr. President, every day foreign criminals wage cyberattacks on American individuals and entities. We have the best computer scientists in the world. Will you appoint a commission on Cybercrime focussed on a next-generation Internet built for trusted actors.
