on driving in residential sidestreets

Ralph Nader wrote, "Erratic driving will always be characteristic of the traffic scene; ehxortation and stricter law enforcement have at best a limited effect." (The Nation, 11 Apr 1959.) He was writing about the safety of vehicles themselves, especially the safety for the drivers and passengers. Largely based on his crusading aided by leaps in technologies, vehicles are now safer for all. Accidents were made safer. (Traffic engineering too has improved road safety, but this was called for later.)

Technologies and regulations, while having huge impact in reducing the imact of impacts, has not been able to address the first point, that human error remains an issue. It may also be likely that while many technologies improve safety for all, vehicles that handle smoothly, are quieter, have tinted windows that mask the driver, and loaded with distracting technologies may increase danger to people outside them.

So what can be done to address speeding in the neighborhood? Behavior modification? Implementation of existing technologies or development of new ones? What are likely solutions? We need them, but can we identify them.

art and mitosis

It's 2018 and when I went to put a comment on a painting at the San Diego Museum of Art, discovered that this blog exists and the last entries were 2007.  Probably there were more entries but as I was beginning to apply for jobs, deleted them.  or maybe this blog was just a way to drive traffic to my other public web presences.

Here's what I posted today:

A few days before seeing this painting I went to an exhibition of  Ramón y Cajal's original drawings on display at the Grey Gallery in NYC.   Cajal delineated cytokinesis with beautiful drawings based on observations through a microscope.  Certainly we cannot avoid comparing many of Cajal's neuron depictions as appearing to be trees.  Made me question, what was Rivera's source material for the cells in the tree canopy?  Is it possible he saw reproductions of Cajal's drawing in particular, or did he have alternate sources to draw from?
