Because I have no idea what yin and yang really are, I decided to go right to the source. It turns out that no one knows. Or, rather, while they are opposite each other and while they together make up everything, no one has any idea what they are. That makes me feel better. Because I clearly have no clue.
But here is a possibility: (1) yin (or yang) is related to the work being done by Harvard Professor Jeff Lichtman in mapping the human brain, while (2) yang (or yin) is the work being done by the various Chabad missionaries, spreading the word. Go ahead: prove me wrong.
I learned about Lichtman and his cohorts in the September-October edition of Harvard magazine. It involves coordinated research taking place in a number of universities to try to figure out how the brain really works. In part it focuses on habits and memories. How do they become habits and memories? Not surprisingly, this involves a lot of technical work: “He and colleagues spent the past decade analyzing one cubic millimeter of cerebral cortex (about the volume of a poppy seed) to create the first detailed map of connections in the human brain. Their analysis has revealed numerous complex structures of great beauty and unknown purpose: nerve fibers growing in whorls……, a new class of neurons with receptors (dendrites) that point only in two, diametrically opposed directions, and aligned with nerve fibers in an unconnected, underlying layer of white matter (none of the scientists have even a theory as to why this alignment exists); and powerful multisynaptic connections, rare instances where nerve fibers make as many as 50 or more connections to a single cell.”
Of course, I don’t understand any of that, and I become more at sea when I continue and read: “Surgeons removed the tissue used in the analysis from the temporal lobe of a 45 year old woman to gain access to an underlying lesion. After infusing and preserving the sample with a hardening resin, the researchers used a diamond knife to slice it into more than 5,000 sections, thinner than a thousandth of a human hair. “Any thicker”, say Lichtman, “and we can’t actually follow the wires through.” Each slice was scanned with a purpose-built multibeam electron microscope (the world’s first when the experiment began) at a resolution so high, he said, that to see all the detail in just one slice would require an array of 750 laptop screens wide by 500 high. Creating the images took six months, running the experiment 24 hours a day, seven days a week. Then came the hard part.”
All I can add is that “the hard part” was totally unintelligible to me, having to do with finding objects in each slice and stitching them together in a three dimensional pattern and color coding them, to obtain “seed sized” samples”, each with 57,000 cells, 230 millimeters of blood vessels and 150 million synapses.
The research, as you may have guessed, is ongoing.
The article, “Mapping the Human Brain” is by Jonathan Shaw, who may or may not have any idea what he was writing about.
As to Chabad, this comes from an article from the most recent edition of Moment magazine titled “From the Margins to the Mainstream” by Sarah Breger and Sue Fishkoff. The story of the rebirth of the Lubavitcher movement is itself well known – how it was brought to the United States by its leadership and reborn into a large, now again worldwide movement, after the destruction of World War II.
But some of the statistics and other facts brought out by the authors are interesting. As you may know, Chabad is centered in Brooklyn, in Crown Heights, but sends its “sluchim” out to create centers elsewhere. There are now approximately 5,000 such locations, of which 2,000 are in the United States, and 3,000 elsewhere in the world. Each is operated by a husband-wife team, and has as its goal pure outreach, reaching Jews of both religious and secular persuasions and giving them a place to congregate and to learn, with no pressure to become observant in any particular way. In fact, the article makes it clear that perhaps 90% of those who attend Chabad functions are not religiously orthodox and will never become so. But Chabad, which started off as what appeared to many as a dangerous fringe movement, is now accepted as mainstream. This is especially true around university campuses and the article claims that the Chabad House at SUNY Binghamton attracts, for its free Friday night dinners, approximately 450 hungry Jews at a time. And through its Jewish Learning Institute, which has 600 locations and a website that draws up to 50 million unique visitors yearly.
Perhaps both of these efforts (the Lichtman experiments and Chabad activities) are related. Perhaps Professor Lichtman needs to figure out why the human brain is so receptive to the Chabad rabbis and their wives (all Chabad rabbis are male, and virtually all married) and their events and courses. The secret undoubtedly lies in those synapses, and when it is discovered, the age old secret of yin and yang will finally be resolved. And the world finally made whole. And by the way, I think that both Professor Lichtman and the Lubavitcher Rebbe (may his memory be for a blessing) would agree.
