[Me] Zvi Har’El

I am a senior lecturer in the Department of Mathematics at the Technion, Israel Institute of Technology. I have been here since 1978, after spending two years in the University of Illinois, Urbana, IL. Later, I spent two more years in Bell Labs, Murray Hill, NJ, and three semesters in IBM Research Lab in Haifa. I am married to Zahava, have three children: Nadav, Gilead (1977-1996) and Michal, and a grand daughter: Gili.

Some of my mathematical papers:

[PDF]Uniform Solution for Uniform Polyhedra [TXT]
Geometriae Dedicata 47 (1993), 57-110.
[PDF]Curvature of Curves and Surfaces — a Parabolic Approach
[PDF]Gauss Formula for the Julian Date of Passover [TXT]
[PDF]The Torah Reading Sequence [TXT]

Some software packages I wrote:

[DIR]kaleido
Uniform Polyhedra - Computation and 3D Display. See the Virtual Reality Models produced by Kaleido and the Java demo.
[DIR]pp
A pretty printing utility.
[DIR]hebgroff
Hebrew fonts for Groff.
[TXT]il-uni.map
Unicode Hebrew/English keyboard map for Linux. The older 8-bit map is still available.
[DIR]gauss
Hebrew calendar programs, using Gauss formula for the Julian date of Passover. If you prefer, the programs are also implemented in Java. FYI, today is . the calendar or an iCalendar file ( holidays only) for the year Anno Mundi, in , style.
You can learn about my ICD and browse in my Jules Verne, Andersen and Escher pages. You can use my public key to send me mail. See you around on the Web!
