A Quote by Sheldon Lee Glashow

One of the principal achievements of physics in the 20th century has been the revelation that the atom is not indivisible or elementary at all but has a complex structure.
The story is told of Lord Kelvin, a famous Scotch physicist of the last century, that after he had given a lecture on atoms and molecules, one of his students came to him with the question, "Professor, what is your idea of the structure of the atom." "What," said Kelvin, "The structure of the atom? Why, don't you know, the very word 'atom' means the thing that can't be cut. How then can it have a structure?" "That," remarked the facetious young man, "shows the disadvantage of knowing Greek."
[When asked "Dr. Einstein, why is it that when the mind of man has stretched so far as to discover the structure of the atom we have been unable to devise the political means to keep the atom from destroying us?"] That is simple, my friend. It is because politics is more difficult than physics.
String theory is 21 st century physics that fell accidentally into the 20th century.
I mean, certainly it's the single biggest event, I think, in terms of popular entertainment, or art even, if you say that, of the 20th Century. It's been film. It's the 20th Century's real art form.
I abhor Earth Hour. Abundant, cheap electricity has been the greatest source of human liberation in the 20th century. Every material social advance in the 20th century depended on the proliferation of inexpensive and reliable electricity.
D-Day represents the greatest achievement of the american people and system in the 20th century. It was the pivot point of the 20th century. It was the day on which the decision was made as to who was going to rule in this world in the second half of the 20th century. Is it going to be Nazism, is it going to be communism, or are the democracies going to prevail?
In science, probably ninety-nine percent of the knowable has to be discovered. We know only a few streaks about astronomy. We are only beginning to imagine the force and composition of the atom. Physics has not yet found any indivisible matter, or psychology a sensible soul.
Earlier this week ... scientists announced the completion of a task that once seemed unimaginable; and that is, the deciphering of the entire DNA sequence of the human genetic code. This amazing accomplishment is likely to affect the 21st century as profoundly as the invention of the computer or the splitting of the atom affected the 20th century. I believe that the 21st century will be the century of life sciences, and nothing makes that point more clearly than this momentous discovery. It will revolutionize medicine as we know it today.
It is my opinion that the 21st century will be the century of play, and the heteroglossic activity of artists in the 20th century has been the forecast.
Molecule, n.: The ultimate, indivisible unit of matter. It is distinguished from the corpuscle, also the ultimate, indivisible unit of matter, by a closer resemblance to the atom, also the ultimate, indivisible unit of matter ... The ion differs from the molecule, the corpuscle and the atom in that it is an ion.
There is a kind of structure for a story that was peculiarly compelling for the radio. I thought I had invented it atom-by-atom sitting in an editing booth in Washington on M Street when I was in my 20s. Then I found out that it is one of the oldest forms of telling a story - it was the structure of a sermon.
One layer was certainly 17th century. The 18th century in him is obvious. There was the 19th century, and a large slice, of course, of the 20th century; and another, curious layer which may possibly have been the 21st.
The 19th century was a century of empires, the 20th century was a century of nation states. The 21st century will be a century of cities.
The 20th century taught us how far unbridled evil can and will go when the world fails to confront it. It is time that we heed the lessons of the 20th century and stand up to these murderers. It is time that we end genocide in the 21st century.
It's fun to sentimentalize the 20th-century lifestyle and the 20th-century brain, but it helps nobody, it makes you look ancient, there's no going back, and you'd be miserable if you did.
There's a sort of eternal, indefinable 20th century quality to 'BTAS.' We never really pegged the decade, but it's anytime in the 20th century, so I often harkened back to things from the '40s or '50s.
