A man who is right every time is not likely to do very much.
FRANCIS CRICKIn my experience most mathematicians are intellectually lazy and especially dislike reading experimental papers. He seemed to have very strong biological intuitions but unfortunately of negative sign.

There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.
FRANCIS CRICK -
An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.
FRANCIS CRICK -
We have to take away from humans in the long run their reproductive autonomy as the only way to guarantee the advancement of mankind.
FRANCIS CRICK -
For simplicity one can think of the + class as having one extra base at some point or other in the genetic message and the – class as having one too few.
FRANCIS CRICK -
A good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.
FRANCIS CRICK -
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
FRANCIS CRICK -
It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less secure than our other deductions about the general nature of the genetic code.
FRANCIS CRICK -
The balance of evidence both from the cell-free system and from the study of mutation, suggests that this does not occur at random, and that triplets coding the same amino acid may well be rather similar.
FRANCIS CRICK -
If, for example, all the codons are triplets, then in addition to the correct reading of the message, there are two incorrect readings which we shall obtain if we do not start the grouping into sets of three at the right place.
FRANCIS CRICK -
A comparison between the triplets tentatively deduced by these methods with the changes in amino acid sequence produced by mutation shows a fair measure of agreement.
FRANCIS CRICK -
How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons.
FRANCIS CRICK -
One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.
FRANCIS CRICK -
It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us.
FRANCIS CRICK -
Evolution is cleverer than you are.
FRANCIS CRICK -
It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.
