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.
Interpretation
Einstein's equations possess a beauty akin to music through their inherent harmony.
In this quote, Edward Witten draws a parallel between the aesthetic appeal of scientific equations and music, suggesting that those who deeply understand scientific concepts can appreciate their beauty just as one appreciates the beauty of art. This highlights a profound connection between science and creativity, indicating that there is an intrinsic harmony in mathematical truths that resonates with the same emotional profundity found in musical compositions.
In practice
During a lecture on physics, this quote can be used to illustrate the artistic side of scientific inquiry.
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.
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.
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.
Science tells us more and more now that there is a strong connection between emotional well-being and health outcomes, and that you can proactively cultivate emotional well-being through relatively simple practices like sleep, social connection and meditation.
There is a single light of science, and to brighten it anywhere is to brighten it everywhere.
Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.
Science reserves the highest reward for those of you who disprove our most cherished beliefs. At any moment someone from any walk of life could come forward and be responsible for a complete revision of our view of everything.
Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.
A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
