Edison on Failure

I have not failed.  I’ve found 10,000 ways that won’t work.
– Thomas Alva Edison (1847 – 1931)

This was an answer to a question from a newspaper reporter when Edison was working on the alkaline battery, btw – it took 10 years and 50,000 experiments. It cost him one million dollars of his own money for research, but he recovered his money from sales of the batteries.

Einstein on Relativity

“When a man sits with a pretty girl for an hour
it seems like a minute.
But let him sit on a hot stove for a minute —
and it’s longer than any hour.
That’s relativity.”
