I would like to give you an example on how you can actually verify some of the Laws outlined in the Pentateuch. In fact, the topic I'm going to talk today is most likely familiar to everyone who reads my blog. I'm talking about TriboElectric effect, or namely when two materials with different electrostatic potential are rubbed (or put together) against one another, which of'course produces static electricity.
Verses of Leviticus 19:19 and Deuteronomy 22:11 describe this effect. Let's take a look:
11 לֹ֤א תִלְבַּשׁ֙ שַֽׁעַטְנֵ֔ז צֶ֥מֶר וּפִשְׁתִּ֖ים יַחְדָּֽו׃ ס11 Thou shalt not wear a garment of divers sorts, as of woollen and linen together.
The word שעטנז "shatnets" here means a combination of the materials with the different electrostatic potential, which of'course results in a very unpleasant spark and jolt. I'm more that sure that all who read this have been shocked before. So if you ever wondered why - this is your answer. And so you can see that these Laws are still in effect very much ;)
Of'course, text does not speak about wool and linen. The words "צמר" (tsemer) and "פשתים" (fishtim) refer most likely to "positive" and "negative" charge potential. So, in my opinion, it is improper to translate it as "wool" and "linen". Text is most certainly not that primitive. In fact, I can't even find the right words here. I think English may not have an equivalent of these words. But I would need to look into this further.
Check out this table. You will find it informative. It will also show you that many modern (synthetic) materials also belong in either of these categories, so the more science advances, the harder it will be to figure out which one is which, and what can be mixed together and what can't be.
