Francis Crick Quotes and Sayings - Page 1
More Francis Crick quote about:
-
“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 -
“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 -
“If revealed religions have revealed anything it is that they are usually wrong.”
-- Francis Crick -
“Haemoglobin is a very large molecule by ordinary standards, containing about ten thousand atoms, but the chances are that your haemoglobin and mine are identical, and significantly different from that of a pig or horse. You may be impressed by how much human beings differ from one another, but if you were to look into the fine details of the molecules of which they are constructed, you would be astonished by their similarity.”
-- Francis Crick -
“The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.”
-- Francis Crick -
“A theory should not attempt to explain all the facts, because some of the facts are wrong”
-- 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 -
“One can say, looking at the papers in this symposium, that the elucidation of the genetic code is indeed a great achievement. It is, in a sense, the key to molecular biology because it shows how the great polymer languages, the nucleic acid language and the protein language, are linked together.”
-- 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 -
“Free will is located in or near the anterior cingulate sulcus.”
-- Francis Crick -
“The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority.”
-- Francis Crick -
“A knowledge of the true age of the Earth and of the fossil record makes it impossible for any balanced intellect to believe in the literal truth of every part of the Bible in the way that fundamentalists do.”
-- Francis Crick -
“A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.”
-- Francis Crick -
“In 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.”
-- Francis Crick -
“If you want to understand function, study structure,”
-- Francis Crick -
“Attempts have been made from a study of the changes produced by mutation to obtain the relative order of the bases within various triplets, but my own view is that these are premature until there is more extensive and more reliable data on the composition of the triplets.”
-- Francis Crick -
“You can do reverse engineering, but you can’t do reverse hacking.”
-- Francis Crick -
“Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.”
-- 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 -
“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 -
“Do codons overlap? In other words, as we read along the genetic message do we find a base which is a member of two or more codons? It now seems fairly certain that codons do not overlap.”
-- 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 -
“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 -
“If the code does indeed have some logical foundation then it is legitimate to consider all the evidence, both good and bad, in any attempt to deduce it.”
-- 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 -
“A good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.”
-- Francis Crick -
“Consciousness is somehow a by-product of the simultaneous, high frequency firing of neurons in different parts of the brain. It's the meshing of these frequencies that generates consciousness, just as tones from individual instruments produce the rich, complex, & seamless sounds of a symphony orchestra”
-- Francis Crick -
“Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself.”
-- Francis Crick -
“To produce a really good biological theory one must try to see through the clutter produced by evolution to the basic mechanisms lying beneath them, realizing that they are likely to be overlaid by other, secondary mechanisms. What seems to physicists to be a hopelessly complicated process may have been what nature found simplest, because nature could only build on what was already there.”
-- Francis Crick
