Better robots, please.

It has been heartbreaking watching my daughter get excited about robot toys– and all of their fantastic behaviors that she has read about and seen in fictional shows — only to be ultimately disappointed at how lame they are in…



People with guns killing people on campuses

There are so many campus murders, usually with guns, that most of us are not too removed from them. Maybe you’ve been on campus during a shooting, and if not, then maybe you are colleagues or personal friends with people who have been though that trauma.

Active alignment for diffraction limited optics in the 1600s

In my optics classes, I often give a brief historical account of Galileo’s telescopes. A point I want to make in this post, is that part of the high performance of Galileo’s telescopes was obtained through careful final adjustments.

A sense of scale: web ads pay for AI/ML

Worldwide spending on all advertising is on the order of 1 trillion USD per year (source: statista). Web ad companies capture large fractions of this. For example, Meta gets about 10%, and Google gets about 20%. Then those companies invest heavily in R&D of various types, including for machine learning (ML) / artificial intelligence (AI)….
