Many Jewish day schools are taking good advantage of technology these days. I was very impressed when I heard about how one Jewish day school in Detroit — Hillel Day School — made it possible for a family to celebrate a bar mitzvah together even though one cousin was in Mongolia.

Eli Falk, an 8th grader at Hillel, wanted his cousin who is working in Mongolia to be a part of his bar mitzvah. So, on a Monday morning in the school’s minyan, through the technology of Skype, Eli’s cousin was right there with the rest of his family — in real time.

One more example of how geographical distance matters less in the 21st century.
