*Our external physical reality is a mathematical structure --* so says Max Tegmark Mathematical_universe_hypothesis <https://en.wikipedia.org/wiki/Mathematical_universe_hypothesis> On Mon, Apr 2, 2018 at 12:42 PM, Dan Asimov <dasimov@earthlink.net> wrote:
If this common discussion subject among mathematicians has come up in math-fun previously, it must have been a while ago:
Is mathematical truth real? I was reminded of this question when I happened to sit next to an esteemed molecular biologist who has strong opinions on the matter: He thinks math is "all in the brain" of humans who think about it. I could not convince him that math has any kind of independent existence — though I certainly believe it myself.
What do other think about this? I would say that mathematical truth is *at least* as real of a thing as physical truth.
