Knowing how things are doesn’t make you see them correctly, doesn’t stop you from seeing things incorrectly. Stare at the image as much as you like, it’s all in vain. It will never surrender the truth, not to your naked eyes; you have to go in armed with a straightedge.

I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.

—Leo Tolstoy, What Is Art?

It’s when the thing interacts that its properties are revealed, even resolved.

Sometimes, when properly regarded, the problem in front of us is understood to be no problem at all, or at least not of the kind we believe it to be.

I am reminded of what Einstein said on the death of his friend: He has departed from this strange world a little ahead of me. That means nothing. For us believing physicists, the distinction between past, present and future is only a stubborn illusion.
