Scientific Confirmation of the Reason for Issur Yichud

For this post, I get off easy, since FKM posted a nice post on the topic.

Check it out here:

Basically, researchers found that when a man was alone with a woman, for a few min., his testosterone levels rose about 8% even if he did not find the woman attractive...

Cool Torah and Science Movie

I found this movie on YouTube. It is a computer animated movie that deals with Torah and Science issues in an entertaining way (I think meant for children). It is made by Nathan Aviezer, author of "In the Beginning: Biblical Creation and Science", and "Fossils & Faith: Understanding Torah and Science" (both available at Amazon). "In the Beginning" is highly recommended by me, as it goes step by step through the Creation narrative and gives a possible scientific explanation of the events that are going on each "day". (He is of the opinion that each "day" was a "phase" of variable length). Anyways, that book is now an entertaining movie, where RamBam, Einstein, and Darwin fly through time in a space ship, so here it is (in 5 parts):

Where Does Rain Come From?

As part of a "double dare" I have to start posting more frequently, so here is a quick post to get things rolling again.

The Midrash Tanchumah on Parashas Mikeitz states the following:

"And from where do the rains descend? Rabbi Eliezer says: All the world drinks from the waters of the Ocean. Rabbi Yehoshua said to him: But are not the waters of the Ocean salty? He said to him: They are sweetened by the clouds of the sky (rakia); for Rabbi Shimon ben Lakish said: Why are they [the heavens] called shechokim? Because they grind [shochakin] the waters and sweeten them, and after that, they descend."

There are a few interesting things to note in this passage:

1) Chazal seems to have known that the water in the Oceans rises up in vapor to form clouds, which in the process filter out the salt, and then the clouds blow onto land to give rain (I don't know if this knowledge was prevalent then or not, but it seems to me to be pretty advanced knowledge for that time).

2) The rakia includes the sky which contains the clouds, meaning that it cannot refer only to the "dome" or to space, etc. but is more inclusive.

3) Rabbi Eliezer says that ALL the world drinks from the Ocean [ok'yanos]. What about underwater springs, rivers, lakes, wells, etc? Some possible answers I can think of off the top of my head (i.e. may be totally wrong) are that for rivers, they flow due to the rain, for lakes, they formed from rain, or from when the land was gathered during creation, and hence from the same body of water as the Oceans (before they complained and became salty), and underwater springs and wells could be formed from absorbed rain.

Very Cool Movie/Music-SlideShow about the Convergance of Torah and Science

I came accross this and thought it was pretty cool. One must excuse the "quote" of Rashi which is given, as I think it is a stretch of what Rashi actually says, however the rest of the quotes are very interesting indeed!
