Suppose we split this chain in two. How can we make another one just like it? If, in the substances of the cells, there is a manufacturing department which brings up phosphate, sugar, and A,B,C,D units not connected in a chain, the only ones which will attach to our split chain will be the correct ones, the complements of BAADC . . . , namely, ABBCD . . . Thus what happens is that the chain splits down the middle during cell division, one half ultimately to go with one cell, the other half to end up in the other cell; when separated, a new complementary chain is made by each half-chain.
richard p. feynman, “six easy pieces”
The nod to DNA is in honor of Thanksgiving and courtesy of Richard Feynman, in “Six Easy Pieces (Essentials of Physics Explained by Its Most Brilliant Teacher),” page 57. c. 1963 Perseus Publishing. I have collected a few books about Quantum Physics. And I have read some pages, yes. The subject is thick and hairy. For me it is challenging, no? I started with “Quantum Questions” by Ken Wilbur, which made me aware of the schism between the new age/dancing wuli master types who want to read grand, eastern spiritual truths into quantum realities, and the people who actually understand the science behind it. So hopefully I will no longer be be in bed with the former. The universe is a trip, yah? Anyway, this is only a tiny little half-page about DNA and biology but I kind of understand it and I liked the picture and everyone in my family is exactly the same so there, have some damn turkey.
