Our heroes

"Prediction is very difficult, especially about the future."

- Niels Bohr

"I can live with doubt and uncertainty. I think it's much more interesting to live not knowing than to have answers which might be wrong."

- Richard Feynman

"In almost every computation a great variety of arrangements for the succession of the processes is possible. One essential object is to choose that arrangement which shall tend to reduce to a minimum the time necessary for completing the calculation."

- Ada Lovelace

"Uncertainty is an uncomfortable position. But certainty is an absurd one."

- Voltaire

"If the flap of a butterfly's wings can be instrumental in generating a tornado, it can equally well be instrumental in preventing a tornado."

- Edward Lorenz

"It is far better to foresee even without certainty than not to foresee at all."

- Henri Poincare

"The idea that the future is unpredictable is undermined every day by the ease with which the past is explained."

- Daniel Kahneman

"If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is."

- John von Neumann

"Information is the resolution of uncertainty."

- Claude Shannon

"The future is an unknown, but a somewhat predictable unknown. To look to the future we must first look back upon the past."

- Albert Einstein

"There is no way that we can predict the weather six months ahead beyond giving the seasonal average."

- Stephen Hawking

"A wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it."

- Herbert A. Simon
