If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.
Murray Gell-MannRead
What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.
Interpretation
Elegant theories in physics are often more accurate than those that are not.
Murray Gell-Mann's quote emphasizes the intrinsic connection between beauty and truth in scientific theories. He suggests that theories which possess elegance and simplicity are more likely to be correct compared to those that are complex and inelegant, highlighting the importance of aesthetics in scientific understanding and discovery.
In practice
In a lecture on theoretical physics, one might reference Gell-Mann's quote to emphasize the pursuit of elegant solutions.
If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.
Just because things get a little dingy at the subatomic level doesn't mean all bets are off.
Sometimes the probabilities are very close to certainties, but they're never really certainties
If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.
The real achievement in discoveries... is seeing an analogy where no one saw one before... The essence of discovery is that unlikely marriage of cabbages and kings β of previously unrelated frames of reference or universes of discourse β whose union will solve the previously insoluble problem.
Now I know what the atom looks like.
Wind power, if not properly planned and sited, can harm birds and bats (although Danish studies of 10,000 bird kills revealed that almost all died in collisions with buildings, cars and wires; only 10 were killed by windmills). Alternative energy sources are absolutely necessary. Global warming will kill birds and bats, as well as other species, in much greater numbers than wind power.
Reply when questioned on the safety of the polio vaccine he developed: It is safe, and you can't get safer than safe.
In the midst of all dwells the Sun. For who could set this luminary in another or better place in this most glorious temple, than whence he can at one and the same time brighten the whole.
Observations indicate that the universe is expanding at an ever-increasing rate. It will expand forever, getting emptier and darker. Although the universe doesnβt have an end, it had a beginning in the Big Bang. One might ask what is before that but the answer is that there is nowhere before the Big Bang just as there is nowhere south of the South Pole.
