I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.
Interpretation
Even incorrect theories can enhance our understanding of complex scientific concepts.
Edward Witten highlights the paradoxical nature of scientific inquiry, where even flawed theories can provoke deeper insights into established fields, such as quantum field theories and the behavior of black holes. This suggests that the journey of exploration in science is as valuable, if not more so, than the pursuit of certainty.
In practice
During a lecture on quantum physics, this quote could illustrate how theoretical exploration is vital for understanding complex phenomena.
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.
But the beauty of Einstein's equations, for example, is just as real to anyone who's experienced it as the beauty of music. We've learned in the 20th century that the equations that work have inner harmony.
You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.
Regardless of any deviations, it was clear I was supposed to end up in math and physics.
Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.
It's an exaggeration to say that I came up with M-theory.
As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery.
No barrier stands between the material world of science and the sensibilities of the hunter and the poet.
It is the very strangeness of nature that makes science engrossing. That ought to be at the center of science teaching. There are more than seven-times-seven types of ambiguity in science, awaiting analysis. The poetry of Wallace Stevens is crystal-clear alongside the genetic code.
The idea that there could be other universes out there is really one that stretches the mind in a great way.
Modern science is fast-moving, and no laboratory can exist for long with a program based on old facilities. Innovation and renewal are required to keep a laboratory on the frontiers of science.
One does not have to appeal to God to set the initial conditions for the creation of the universe, but if one does He would have to act through the laws of physics.
