Perhaps one of the most interesting things about Judaism is is how Judaism engages technological innovations. Sometimes Judaism embraces technology; even the most hidebound of Orthodox Jews will use microphones and loudspeakers to deliver a Torah lecture to a large audience. On the other hand even the most liberal of Jewish communities will insist that the Torah scroll in their synagogues be hand-written by a scribe who uses a pen dipped into ink.
In the coming sessions ( probably three) we will see how the Halacha treated three technological innovations. They are the wax candle, the printing press and the incandescent light bulb.
I hope that you will find the classes interesting.
