Thought for the Day: Even a Ma'she'hu Has a Shiur

I once had a boss who was Canadian and atheist.  Nothing in essence wrong with either one of those, of course; one is an accident of birth, the other a lack of thinking. This guy, however, was jingoistic about both.  After just a short time he let me know that I was from the NSM.  "NSM?", I asked quizzically.  "Yes!  You guys don't speak clearly and it comes out 'Nited States 'Meirca."  I looked right back at him and said defiantly, "At least I have my two front teeth; eih!"  (I didn't really, but I wish I had.  The truth is, he could have been reacting to me referring to an American as someone from the United States, implicitly implying that Canada was not in America.)  Anyway, that tells you something about his personality.

Of course religion in general, and my religious observance in particular, was another favorite target of his "wit".  He once came gleefully bounding into my office.  "So.... you aren't allowed to eat pork, right?"  "Right."  (Obviously this was not why he had that cat-that-ate-the-canary look on his face, but I figured it was safe enough to answer that question in the affirmative.)  "You aren't allowed to eat any amount at all; right?"  (Ah... that's what we are up to.)  "Right.", I answered innocently; then added, "Of course, once it is less that one part in 60 then it is as if it is not there."  His expressoins changed to the cat-that-just-realized-it-was-his-kitten-and-not-a-canary-that-he-ate look.  He had been all ready to give me grief about how it is impossible to ensure that there isn't even one molecule of pork (not that there is anything called a pork molecule, of course) in my food and/or air.  yada yada

Just between us, though, we do have a shiur known as "ma'she'hu"; literally: whatever it may be.  (You try figuring out how to punctuate transliteration!)  During Pesach, of course, we are forbidden to eat even a ma'she'hu of chameitz.  Does that really mean "even a molecule of chameitz"? (again, there is not such thing as a molecule of chameitz, but you know what I mean.)  I have even heard seemingly crazy stories about people not drinking water from the Kineret during Pesach because of (non-frum/non-jewish) fishermen using chameitz for bait.  Does it really go that far?  Do I need to start wearing a surgical mask lest I catch a whiff of Dunkin Donuts from downtown?

I do not, says Halichos Shlomo; ma'she'hu is also a shiur.  Assur b'ma'she'hu means that in its current concentration the issur cannot be tasted.  However, if the amount is so small that it would not be detectable by normal human senses even if the issur were to be isolated, then the mixture is kosher l'chatchila.  In fact, that tiny amount of issur itself is not even assur, since it is undetectable by normal human senses.  Yet another example of lo nitna torah l'malachei ha'shareis -- the Torah was not given to ministering angels.

Too bad for the surgical mask vendors.

Thought for the Day: Thanking HaShem Each and Every Day for Solid Land Near Water

Each and every morning, a Jew is supposed to view himself as a new/renewed creation, ready for a new day of building his eternal self through Torah and mitzvos.  We begin the day with 16 brachos to praise/thank/acknowledge HaShem for giving us all the tools we need to succeed.  We have a body, soul, and intellect.  We have vision, mobility, and protection from the elements.  Among those brachos, we have one that perhaps seems a bit out of place: רוקע הארץ על המים/Who spreads out the land on/over the water.  After all, it's nice to have a dry place to walk, but does that compare to the gratitude I have for a working body and vision?  As it turns out, I should; as explained by the R' Rajchenbach, rosh kollel of Kollel Zichron Eliyahu (aka, Peterson Park Kollel).  Your best bet is to listen to the shiur; very distant second is to continue, which I hope will whet your appetite for the real thing.

First... since we have dry land, I don't have to slog to work through even a foot…

Thought for the Day: Using a Mitzvah Object for Non-Mitzvah Purposes

As I am -- Baruch HaShem -- getting older, I am more cognizant of the fact that I'd like to stay as healthy as possible right up the moment I leave this world.  Stuff hurting is not the problem (I am told there is an old Russian saying that once you are 40, if you wake up and nothing hurts -- you're dead), stuff not working, however, is a problem.  To that end, for several years now I commute to work by bicycle (weather permitting, 30 minutes on an elliptical machine when weather does not permit).  I recently took up some upper body weight training.  Not because I want to be governor of California, just simply to slow down loss of bone mass and extend my body's healthy span.  Simple hishtadlus.  I have an 18 month old grandson who is just the right weight for arm curls (yes... I am that weak), so I do about 10 reps when I greet him at night.  He laughs, I get my exercise; all good.  (Main problem is explaining to the older ones why zeidy can't give them the same "…

Thought for the Day: Hydroponically Grown Humans... I Feel Sick

I am quite openly not at all objective about abortion in particular and the treatment of human embryos and fetuses in general.  I am, after all, the survivor of a failed abortion attempt.  Not "thought about it, but couldn't go through with it"; not "made appointment, but then chickened out at the lost moment"; but, "tried a procedure, but was unsuccessful in attempt to abort".  Nonetheless, I try very hard to listen to the liberal arguments (which I also used to chant as part of the general liberal catechism), and am genuinely empathetic to the plight of women who find themselves in that difficult position.

What I heard on NPR this morning, however, has left me feeling physically ill.  You can read about it, if you like, but here's the bottom line:  Scientists in Cambridge have achieved a new record, they fertilized a human ova and then kept it alive in vitro (that is, in a test tube/petri dish in a laboratory) for 14 days.  The scientist involve…
