Beauty and Truth in Physics
1)
Beauty, truth and ... physics?
/ Murray Gell-Mann at TED 2007 /
Armed with a sense of humor and laypeople's terms,
Nobel winner Murray Gell-Mann drops some knowledge
on TEDsters about particle physics, asking questions like,
Are elegant equations more likely to be right than inelegant ones?

Beauty Is Truth, Truth Is Beauty, and Other Lies of Physics
/ by Sabine Hossenfelder , 15/JUL/2018 /
Who doesn’t like a pretty idea?
Physicists certainly do. In the foundations of physics, it has become
accepted practice to prefer hypotheses that are aesthetically pleasing.
Physicists believe that their motivations don’t matter because
hypotheses, after all, must be tested. But most of their beautiful ideas
are hard or impossible to test. And whenever an experiment comes
back empty-handed, physicists can amend their theories
to accommodate the null results.

Simulation and Reality.

No, we probably don’t live in a computer simulation
Wednesday, March 15, 2017
According to Nick Bostrom of the Future of Humanity Institute, it is likely that we live in a computer simulation. And one of our biggest existential risks is that the superintelligence running our simulation shuts it down.
The simulation hypothesis, as it’s called, enjoys a certain popularity among people who like to think of themselves as intellectual, believing it speaks for their mental flexibility. Unfortunately it primarily speaks for their lacking knowledge of physics.

Among physicists, the simulation hypothesis is not popular . . . .
Proclaiming that “the programmer did it” doesn’t only not explain anything - it teleports us back to the age of mythology.

Stephen Wolfram (from Wolfram research) recently told John Horgan that:
“[Maybe] down at the Planck scale we’d find a whole civilization
that’s setting things up so our universe works the way it does.”

[Maybe] down at the Planck scale there is quantum existence
that can generate the whole Material universe.
====
Planck scale of existence is described by Quantum theory.
But . . . .
“[Quantum mechanics] describes nature as absurd
from the point of view of common sense.
And yet it fully agrees with experiment.
So I hope you can accept nature as She is - absurd.”
/ Richard Feynman /
