No Need for Erroneous Assumptions in Science
The laws of nature, as we understand them, are the foundation of our knowledge in natural things. So much as we know of them has been developed by the successive energies of the highest intellects, exerted through many ages. After a most rigid and scrutinizing examination upon principle and trial, a definite expression has been given to them; they have become, as it were, our belief or trust. From day to day we still examine and test our expressions of them. We have no interest in their reten... 1

Science is More Than Lone Geniuses
The progress of science depends less than is usually believed on the efforts and performance of the individual genius ... many important discoveries have been made by men of ordinary talents, simply because chance had made them, at the proper time and in the proper place and circumstances, recipients of a body of doctrines, facts and techniques that rendered almost inevitable the recognition of an important phenomenon. It is surprising that some historian has not taken malicious pleasure in w... 1 notes

Discoverers Are Not Heroes
Do not expect to be hailed as a hero when you make your great discovery. More likely you will be a ratbag—maybe failed by your examiners. Your statistics, or your observations, or your literature study, or your something else will be patently deficient. Do not doubt that in our enlightened age the really important advances are and will be rejected more often than acclaimed. Nor should we doubt that in our own professional lifetime we too will repudiate with like pontifical finality the most...Folksonomies: discovery

Discovery By Wislawa Szymborska
I believe in the great discovery.
I believe in the man who will make the discovery.
I believe in the fear of the man who will make the discovery.
I believe in his face going white,
His queasiness, his upper lip drenched in cold sweat.
I believe in the burning of his notes,
burning them into ashes,
burning them to the last scrap.
I believe in the scattering of numbers,
scattering them without regret.
I believe in the man's haste,
in the precision of his movements,
in his free will.

1 A chilling and insightful poem about faith and how it blinds people to evidence.

A Reversible NAND Gate
The great discovery of Bennett and, independently, of Fredkin is that it is possible to do computation with a different kind of fundamental gate unit, namely, a reversible gate unit. I have illustrated their idea--with a unit which I could call a reversible NAND gate. It has thre inputs and thre outputs. Of the outputs, tow, A' and B', are the same as two of the inputs, A and B, but the third input works this way. C' is the same as C unless A and B are both 1, in which case it changes whateve...Folksonomies: computing

notesFeynman describes a reversible logic gate, with three inputs and three outputs, one of which tracks the change in input and output, allowing the computer to reverse its operation and potentially pursue a different route.
