Dear Prof. Dr. Leonard Mlodinow,

Not having the advantage of an advance copy, but following your Cambridge friend since the early ‘70s and enjoying his cooperation with our Schrödinger What is Life?  tribute in 1979 at MIT,  your collective work is somewhat known to me.

I have some simple-albeit-trick questions for you about basic structure and then a comment about metaphor.

The foundations, first principles of logic and life, begin with some ordering condition that creates continuity. We are able to measure. There is quantitative analysis. A science can emerge. A space is defined. Push the points and lines into three dimensions and an equals sign readily emerges.  Relations are possible and can be quantitatively defined. Continuity equations now lead to symmetry equations.

Bear with me please.

Introduce duration and symmetries render all the diversity and complexity we know. Some of these dynamics are actually perfected in various manifestations of harmony. That is a simple overview of quantities.

With harmony, however, within the human condition, something rather special happens.  We begin to have qualitative analysis.  Numbers take on special meaning.    There is interiority. Then, comes logic, linguistics, and a psychology and all the other expressions of humanity. Among those expressions are folks who think about universals. Put those in quantitative language and you have science, put them in qualitative language and you have personal dynamics, business, religion and the arts.

Too simple? I don’t think so.

Though not highly regarded by some, I enjoyed the friendship of David Bohm who encouraged us in a class to spend some time thinking about points, lines, triangles and tetrahedrons.  When Bohm died in 1992, I took down his book, Fragmentation and Wholeness, that he had given to me as his guest in his class. After reading just a few pages, I thought, “Why did we not ask what is inside the tetrahedron?” I made a simple paper model.

For over a century, most discussions about simple geometries are not encouraged. As a result, most academics and practitioners of science could not answer the simple question, “What is perfectly enclosed within the tetrahedron?” School children should be able to quickly answer. At the center of the tetrahedron is the octahedron which poses an even more difficult challenge for most. Again the kids should know better. At Princeton a few years ago, I asked the surreal numbers man, John Conway (a good gaming guy), the question. He bought some time by asking me why I was so hung up on the interior structure of the octahedron. Then he said, “Let’s figure it out,”  and of course, he did. Though a few of Bucky Fuller’s people could have answered the question, very few can.

And therein lies answers beyond our wildest dreams. The simplest interior structure of the octahedron is not simple at all. And, therein is not only the GUT, the TOE and a few TOES as well, there is more. This is what is. It is pure thought and for some reason, that exploration , if we prevail, is just about to explode. We’ll finally get to see the cohesiveness of knowledge, all of knowledge. Make it personal, twist a few metaphors within it, and you can get a lot of God talk. Keep it abstract and quantitative, and you have a science.

I know that you didn’t ask, but I thought you might enjoy a slightly different twist on our mutually-shared views of our universe.

Thank you.

Best wishes,

-Bruce
