In physics, your solution should convince a reasonable person. In math, you have to convince a person who's trying to make trouble. Ultimately, in physics, you're hoping to convince Nature. And I've found Nature to be pretty reasonable.

Interpretation

What this quote means

In physics, the validity of a solution relies on convincing a reasonable observer, while in math it requires convincing a skeptic. Ultimately, success in physics means aligning with the laws of Nature, which tends to be fair and logical.

The quote by Frank Wilczek emphasizes the differing nature of validation in physics compared to mathematics. In physics, when one proposes a solution, it is vital to satisfy a reasonable individual's understanding and acceptance of the explanation. Conversely, in mathematics, one must often meet the demands of critics, who will seek to challenge and scrutinize any proof. The ultimate goal of physics is to align one's findings with the innate logic of Nature itself, which Wilczek suggests is fundamentally reasonable. This reflects the intricate relationship between theoretical reasoning and the empirical observations that define the physical world.

We're at a point in history were we have to become a part of the neighborhood of inhabited planets, like a neighborhood of a community, which we have not even acknowledged that that community exists up until this point.

A man has no reason to be ashamed of having an ape for his grandfather. If there were an ancestor whom I should feel shame in recalling it would rather be a man who plunges into scientific questions with which he has no real acquaintance, only to obscure them by an aimless rhetoric.

People who look for the first time through a microscope say, 'Now I see this, and then I see that,' and even a skilled observer can be fooled. On these observations I have spent more time than many will believe, but I have done them with joy, and I have taken no notice of those who have said, 'Why take so much trouble,' and, 'What good is it?'

My whole interest is, how do you use evolution as an innovation engine? How does evolution solve new problems that life faces? And to have a system that can create a whole new chemical bond that biology hasn't done before, to me, demonstrates the power of nature to innovate.

A big misconception is that a black hole is made of matter that has just been compacted to a very small size. That's not true. A black hole is made from warped space and time.
