A Quote by Stefan Hell
According to the belief, molecules closer together than 200 nanometers could not be told apart with focused light. This is because, in a packed molecular crowd, the molecules shout out their fluorescence simultaneously, causing their signal, their voices, to be confused.

We know what molecules are needed to sense light - what turns that signal that detects light into an electrical signal. We know how smells are detected. But we have a vast number of senses for which we know what the signal is, but we don't know what the receiver is.
Studying organisms at a molecular level was totally compelling because it was moving from being a naturalist, which was the 19th-century kind of science, to being very focused and really getting to the heart of these molecules.
Suppose that you could mark the molecules in a glass of water; then pour the contents of the glass into the ocean and stir the latter throughly so as to distribute the marked molecules uniformly throughout the seven seas; if then you took a glass of water anywhere out of the ocean, you would find in it about a hundred of your marked molecules.
The words are strung together, with their own special grammar-the laws of quantum theory-to form sentences, which are molecules. Soon we have books, entire libraries, made out of molecular "sentences." The universe is like a library in which the words are atoms. Just look at what has been written with these hundred words! Our own bodies are books in that library, specified by the organization of molecules-but the universe and literature are organizations of identical, interchangeable objects; they are information systems.
My aging body transmits an ageless life stream. Molecular and atomic replacement change life's composition. Molecules take part in structure and in training, countless trillions of them. After my death, the molecules of my being will return to the earth and sky. They came from the stars. I am of the stars.
Why are atoms so small? ... Many examples have been devised to bring this fact home to an audience, none of them more impressive than the one used by Lord Kelvin: Suppose that you could mark the molecules in a glass of water, then pour the contents of the glass into the ocean and stir the latter thoroughly so as to distribute the marked molecules uniformly throughout the seven seas; if you then took a glass of water anywhere out of the ocean, you would find in it about a hundred of your marked molecules.
The molecules that comprise our body are traceable to the crucibles of the centers of stars.These atoms and molecules are in us because, in fact, the universe is in us. And, we are not only figuratively, but literally, stardust.
I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule?
My own training is in the field of neuroendocrinology and I really became very fascinated many years ago with the molecules of emotion, molecules that we call neuropeptides.
The neuro-biology of playing a musical instrument is completely scientific, but it’s also an absolute miracle, that you’re taking basically a calcium bucket filled with salt-water that’s run by a weak electrical signal, and you’re using it to move your flesh around in order to manipulate an instrument which disturbs air molecules between you and the listener, and then the listener’s ears picks up those disturbed air molecules which generates a weak electrical signal to their calcium bucket full of salt water, and they feel a feeling. That’s miraculous, and that’s where I live.
And what is literature, Rabo," he said, "but an insider's newsletter about affairs relating to molecules, of no importance to anything in the universe but a few molecules who have the disease called 'thought'.
UV is bad for molecules because its high energy breaks the bonds between a molecule's constituent atoms. That's why UV is bad for you, too: it's always best to avoid things that decompose the molecules of your flesh.
Eventually I realised there must be a way by playing with the molecules; trying to turn the molecules on and off allows you to see adjacent things you couldn't see before.
I have lived much of my life among molecules. They are good company. I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule? I tell them, Try to feel like a molecule; and if you work hard, who knows? Some day you may get to feel like a big molecule!
It will be possible, through the detailed determination of amino-acid sequences of hemoglobin molecules and of other molecules too, to obtain much information about the course of the evolutionary process, and to illuminate the question of the origin of species.
Once we understand how molecules are formed, we can manipulate them. If you can manipulate molecules, you can manipulate genes and matter, you can synthesize new material - the implications are just unbelievable.
