A Quote by Giulio Natta
If the polymer chain assumes a helicoidal conformation in the crystalline state, and if it does not contain asymmetric carbon atoms, it can be expected that either helices of the same sense, or, in equal ratio, helices of opposite sense are represented in the lattice.

X-Ray crystallography is nowadays an accurate and rapid method of determining conformation in the crystal lattice, which conformation usually corresponds to the preferred conformation in solution.
Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life-the carbohydrates, amino acids, proteins, and lipids-is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.
Now what is just and right is to be interpreted in the sense of 'what is equal'; and that which is right in the sense of being equal is to be considered with reference to the advantage of the state, and the common good of the citizens. And a citizen is one who shares in governing and being governed. He differs under different forms of government, but in the best state he is one who is able and willing to be governed and to govern with a view to the life of virtue.
There's something about a roller coaster that triggers strong feelings, maybe because most of us associate them with childhood. They're inherently cinematic; the very shape of a coaster, all hills and valleys and sickening helices, evokes a human emotional response.
Even when they are saturated in the sense of the older theory of valence, the elementary atoms still possess sufficient chemical affinity to bind other seemingly also saturated atoms and groups of atoms, under generation of clearly defined atomic bonds.
[Professor Bragg asserts that] In sodium chloride there appear to be no molecules represented by NaCl. The equality in number of sodium and chlorine atoms is arrived at by a chess-board pattern of these atoms; it is a result of geometry and not of a pairing-off of the atoms.
God has a tremendous sense of humor! Religion remains something dead without a sense of humor as a foundation to it. God would not have been able to create the world if he had no sense of humor. God is not serious at all. Seriousness is a state of disease; humor is health. Love, laughter, life, they are aspects of the same energy.
Italy is still very much the same place it was 2,000 years ago. Italians are still the same .. there's a sense of beauty and a sense of dignity and a sense of living life to the full that infects everyone.
If the atoms in [a] decimetre cube of lead were all put into a chain side by side the same distance apart as they are in the normal lead, the strings of atoms so formed would reach over six million million miles.
To demand 'sense' is the hallmark of nonsense. Nature does not make sense. Nothing makes sense.
[Buddhism and Christianity] are in one sense parallel and equal; as a mound and a hollow, as a valley and a hill. There is a sense in which that sublime despair is the only alternative to that divine audacity. It is even true that the truly spiritual and intellectual man sees it as sort of dilemma; a very hard and terrible choice. There is little else on earth that can compare with these for completeness. And he who does not climb the mountain of Christ does indeed fall into the abyss of Buddha.
When we sense something, it is due to the movement of atoms in space. When I see the moon it is because "moon atoms" penetrate my eye.
I will venture to assert, that a just translation of any ancient poet in rhyme is impossible. No human ingenuity can be equal to the task of closing every couplet with sounds homotonous, expressing at the same time the full sense, and only the full sense of his original.
They have a crystalline sense of right and wrong; it disappears when they walk out the door with their M.B.A.
[The American public demands] a sense of legitimacy from and in the presidency. There is more to this than dignity, more than propriety. The president is expected to personify our betterness in an inspiring way, to express in what he does and is, not just what he says, a moral idealism which, in much of the public mind, is the very opposite of politics.
The Republicans, in the various arguments, repeat exactly the same phrases one after another, with no sense of embarrassment, no sense of shame, no sense of intellectual integrity.
