And so the journey arrives in the here and now – Cusanus, Bruno, Pascal, Kant, Einstein, and Witten. Edward Witten is the last in our line – and the first to be contiguous with his immediate predecessor. For four years, between 1951 and 1955, they actually shared our little globe. He is also alive today. I suppose it would be fair to ask is Witten now, where Einstein once was. In the late Twenties, or early Thirties Einstein would have been, oh let’s say 52-53. Witten today is about 57. For certain the locale is the same. Both led The Institute for Advance Study, Princeton, New Jersey. The search is similar – one sought and the other seeks a unified theory of everything. The latter is still producing, but has the rate slowed?
Awhile back I wrote about me: “A younger mind than mine can compute differently by holding more facets clearly in context. Does that automatically make his product superior to mine? Is he always closer to the truth?” I didn’t answer then, still can’t – but I do wonder if it’s germane. Perhaps it is possible that, with experience, we get better at synthesis. Youth generally doubts it. On such a question rests the possibility of Witten succeeding where Einstein failed. Let’s at least see how far he has gotten.
He won a MacArthur Genius Grant in 1982, The Dirac Medal in 1985, A Fields Medal in 1990, The National Medal of Science in 2003, and an Honorary Doctor of Science, from Cambridge University, 2006. He is primarily a mathematical physicist - the Fields Medal is the highest honor for a mathematician. He marries math to Quantum Field Theory. Of course his math is way beyond me – actually beyond almost everybody – but way, way beyond me. However he has never won a Nobel Prize, maybe never will. That’s at least partly because the technology to prove some of his theories won’t be invented for a long, long time. Still the terascale of the Large Hadron Collider, just about to come online at CERN, could help. Of course he could win in 2021, as a fitting centennial to Einstein’s.
Some of his concepts such as anomaly cancellation, theory equivalence, mirror symmetry and gauge invariance are almost comprehensible to a layman, even if the math is not. Some of them, under varying names and degrees of applicability, trace back to Cusanus, Bruno, Pascal, and Kant. Even more go back to Einstein. Man, it seems, has been struggling with infinity under various guises almost forever. If the one dimensional trajectory becomes a two dimensional orbit, is that different in kind from the debate between a point and a wave? Little loops of vibrating string oscillating in varying harmonies are a way of looking at things that can resonate in the mind, if not yet under the macro microscope. It is successful primarily because of the fuzziness it produces. Space-time itself becomes fuzzy. Thirteen/WNET used the expression “Quantum experiments were more actuarial than actual.” Maybe solid things became fuzzy waves, but produced good vibrations. Is that the extra dimensions? Maybe, maybe not, or maybe sometimes on average, if it’s a Planck length or universal.
There are a few techie sorts, a few nerds, and a lot of communists who would like to do away with God in all H. guises. For the rest of us – Buddhists, Catholics, Protestants, Muslims, Hindus and a host of others – we know there is a PBU. From Cusanus to Einstein and maybe Witten too – we don’t really know his views on this subject. He was raised in a Jewish family – beyond that we don’t know, and perhaps shouldn’t. Some years ago on a physics forum they asked the question: “Does the world’s smartest man, Edward Witten, believe in God?” The overwhelming response was who cares? What does it matter? It is not his area of expertise… and other such comments. They had a point, but since it was a physics forum, they might also have had a bias. There was an article in National Geographic (March, 2008) entitled The God Particle by Joel Achenbach. It was a fascinating piece on the LHC at CERN. Still, I thought it a bit presumptuously titled. Journalists and physicists, both it seems, have to sell magazines and colliders respectively. At any rate that brings us back to Cusanus and full circle.
