Thought for the Day

Here's a great insight from the eminent physicist Richard Feynman (1918-1988), who worked on the Manhattan Project and later won the Nobel Prize:

"It is in the admission of ignorance and the
admission of uncertainty that there is a hope
for the continuous motion of human beings
in some direction that doesn't get confined,
permanently blocked, as it has so many times
before in various periods in the history of man."
