Discovering memristors

David Warren is back from his annual vacation, and is in fine form. I’ve been meaning to comment on the recent discovery of memristors (the “fourth” fundamental circuit element, after resistors, inductors, and capacitors) for a while now, but I rather prefer Mr. Warren’s approach to it:
…the empirical outlook of science needs balancing against the philosophical outlook, which demands context, and seeks breadth. It is incidentally also why the greater advances in scientific understanding are often made by rank amateurs — people like Einstein working in places like Swiss patent offices, who can see the forest in spite of all the trees.
It is also why such a disproportionate number of the greatest theoretical advances have been made by religious “nutjobs” (in the current parlance) — from the evangelical Newton, to the Catholic fundamentalist Galileo, to monks such as Copernicus, Mendel, and Lemaître — people chilled out by disposition, with a grand view of nature and her infinitely distant, but transubstantially present, God. Without such vision, we all tend to become easily panicked data crunchers.
I was struck this week by another science story, also in Nature magazine. The techies at Hewlett-Packard have successfully fabricated “memristors,” a fourth building block for electronic circuits (after capacitors, resistors, and inductors). The achievement promises significant advances in computer memory and processing.
The possibility of memristors was first established by Leon Chua, a professor at Berkeley, in 1971. He said this week, “I’m thrilled because it’s almost like vindication. Something I did is not just in my imagination, it’s fundamental.”
I love the implicit faith and humility in that statement. The man is thrilled because he didn’t really invent anything after all, merely discovered (”dis-covered”) something already there, in nature or “the mind of God.”
And THAT is where authority comes from. Not from “scientists.”
The thought of scientific discovery is thrilling, but so often it seems the frame of mind that is put in to the necessary research is…lacking in a certain internal humility. Leon Chua knew, from mathematical circuit models, that something more was yet to be discovered; resistors, inductors, and capacitors, though important, did not tell the whole story. But he didn’t create memristors — he understood from looking at the math that the fundamental laws that governed the Universe required that something like memristance exist, even if no technology corporation had yet constructed a memristor.
And indeed, all congratulations to both Leon Chua and the researchers at HP — this discovery is a significant advance in computing technology.
But even in saying that sentence, what is the most important reflection one can make? David Warren points to it — the term “discovery.” For indeed, this is not something new that has emerged suddenly, but instead is something very old which has now been found.
God is rather wont to array things in just such a way that this sort of thing transpires from time to time.
