Goodwill Hunting

The Orange Nude by Roberta Malkin

A few days ago I received an email from a guy I didn’t know named Bob:

I think this was done by your mother. Might want to pick it up. Very good work and it caught my eye. Bob

He included a link to a Goodwill auction, where I immediately recognized one of my mother’s early drawings, at least 30 years old judging by the style. It was being auctioned out of Portland, Oregon – odd given that my mother (Roberta Malkin) has lived and worked her entire life in Chicago.

The Laser Eruv

The Laser Eruv

An image from the laser eruv, produced by shooting a red laser out a window and into a surveillance camera mounted across the street.

An eruv is a symbolic boundary – a wire – that is suspended around orthodox Jewish communities throughout the world. It is typically strung between utility poles above the city streets, a somewhat fragile arrangement prone to storm damage and requiring laborious upkeep.

The laser eruv, in contrast, creates a boundary out of continuous beams of light. Obstructions like the branch of a tree will interrupt the flow of light without damaging the apparatus. As such, it represents the most significant advancement in eruv technology since the telephone pole.
