Top 283 Molecules Quotes & Sayings - Page 4

We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star.

If I let my fingers wander idly over the keys of a typewriter it might happen that my screed made an intelligible sentence. If an army of monkeys were strumming on typewriters they might write all the books in the British Museum. The chance of their doing so is decidedly more favourable than the chance of the molecules returning to one half of the vessel.

What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences. The secret of antibody diversity would emerge from that. Fortunately at the time I was sufficiently ignorant of the subject not to realise how naive I was being.

Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Quantum physics forms the foundation of chemistry, explaining how molecules are held together. It describes how real solids and materials behave and how electricity is conducted through them... It enabled the development of transistors, integrated circuits, lasers, LEDs, digital cameras and all the modern gadgetry that surrounds us.

The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for its shape and comfort.

I believe from my many experiences that the spirit world is more real, more solid, than this earth in which we live. In truth, ours is a world of illusion. All that seems so solid is yet just a mass: molecules locked together, forming an impression of solid matter that in fact is not solid at all.

Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the pant's unique ability to synthesize them from sunlight.

The emotion is the execution of a very complex program of actions. Some actions that are actually movements, like movement that you can do, change your face for example, in fear, or movements that are internal, that happen in your heart or in your gut, and movements that are actually not muscular movements, but rather, releases of molecules.

Physicist Isador Isaac Rabi, who won a Nobel Prize for inventing a technique that permitted scientists to probe the structure of atoms and molecules in the 1930s, attributed his success to the way his mother used to greet him when he came home from school each day. "Did you ask any good questions today, Isaac?" she would say.

What is it about fire that's so lovely? No matter what age we are, what draws us to it?...The thing man wanted to invent, but never did...If you let it go on, it'd burn our lifetimes out. What is fire? It is a mystery. Scientists give us gobbledygook about friction and molecules. But they don't really know. Its real beauty is that it destroys responsibility and consequences.

My father worked for Unilever, running a mass-spectrometry lab - mass spectrometry is a process for elucidating the chemical structures of molecules, which means that he presided over a legal form of corporate espionage, breaking down the component parts of competitors' products in order to copy them.

If you want to change the world, then be your own focus for a celebration of life. Really, fundamentally, at the very core of your being, be thankful you are alive, that you've got this opportunity, with these molecules, at this moment. Be thankful! Be a celebrant! Be thankful that you are alive and then look around to see who else is at the party!

The universe and the Laws of Physics seem to have been specifically designed for us. If any one of about 40 physical qualities had more than slightly different values, life as we know it could not exist: Either atoms would not be stable, or they wouldn't combine into molecules, or the stars wouldn't form heavier elements, or the universe would collapse before life could develop, and so on...

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

The problem is how do molecules react. Because if you want to transform a molecule into something useful or something you're interested in, it helps a lot to understand the structure. That means you can explore much more complicated systems, much more complicated reactions.

It's hard to say goodbye for good at any time or any place. It's harder still to say it through a meshed wire. It crisscrossed his face into little diagonals, gave me only little broken-up molecules of it at a time. It stenciled a cold, rigid frame around every kiss.

Suave molecules of Mocha stir up your blood, without causing excess heat; the organ of thought receives from it a feeling of sympathy; work becomes easier and you will sit down without distress to your principal repast which will restore your body and afford you a calm, delicious night.

We're inquiring into the deepest nature of our constitutions: How we inherit from each other. How we can change. How our minds think. How our will is related to our thoughts. How our thoughts are related to our molecules.

As a bio major, I figured "free will" meant chemicals in your brain telling you what to do, the molecules bouncing around in a way that felt like choosing but was actually the dance of little gears--neurons and hormones bubbling up into decisions like clockwork. You don't use your body; it uses you.

It would be great if you could cool the water and immobilise the molecules, though keeping the structure, because when it's frozen, when it's immobilised, you can have it in the electron microscope and the water will not evaporate because in the electron microscope, it must be under vacuum, and water at normal temperature evaporates.

The whole material world. It doesn't actually exist. Matter is not material. It's made up of atoms that are moving at lightning speeds around huge empty spaces. So as you go beyond the appearance of molecules, you end up with a subatomic world, and if you go beyond that you end up with nothing. Nothing is the source of everything.

I know that, except for carbon, there would be no life in the universe. Except for this one atom, there would be no life. Well, why? When you think about it, it does get spooky. Encountering these molecules are spiritual experiences similar to what I remember in church as a child, only these are more serious.

Beyond a critical point within a finite space, freedom diminishes as numbers increase. This is as true of humans as it is of gas molecules in a sealed flask. The human question is not how many can possibly survive within the system, but what kind of existence is possible for those who so survive.

When we think of what is necessary for the phenomenon that we call life, we think of compartmentalization, keeping the molecules which are important for life in a membrane, isolated from the rest of the environment, but yet, in an environment in which they actually could originate together.

Such is the art of writing as Dreiser understands it and practices it--an endless piling up of minutiae, an almost ferocious tracking down of ions, electrons and molecules, an unshakable determination to tell it all. One is amazed by the mole-like diligence of the man, and no less by his exasperating disregard for the ease of his readers.

Local order in parts of the universe is always possible at the expense of heat and disorder dissipated to the external environment. The human body is one example: we take in energy from our environment to build up complex molecules that help power our bodies, and, in doing so, we release heat to the world around us.

The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.

The world is not made of molecules, the world is made of stories.

As soon as we touch the complex processes that go on in a living thing, be it plant or animal, we are at once forced to use the methods of this science [chemistry]. No longer will the microscope, the kymograph, the scalpel avail for the complete solution of the problem. For the further analysis of these phenomena which are in flux and flow, the investigator must associate himself with those who have labored in fields where molecules and atoms, rather than multicellular tissues or even unicellular organisms, are the units of study.

I've always found the rhetoric of mainstream civil rights leaders and organizations to be far too timid, accommodationist, and gradualist. It always seemed to me that they behaved like meek and gentle supplicants begging the oppressor for a few crumbs of justice, for a few molecules of citizenship rights.

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.

I'm too drunk to recall much of what I've said. Which, come to think of it, is probably just as well, judging by the way people who are normally quite sensible dissolve into gibbering, rude, opinionated and bombastic idiots once the alcohol molecules in their bloom-stream outnumber the neutrons, or whatever. Luckily, one only notices this if one stays sober oneself, so the solution is as pleasant (at the time, at least) as it is obvious.

We need to go back to our relationship with nature and understand that those trees are our lungs. The earth is recycling as our body. The rivers are our circulation. This air is our breath. And the star stuff, the carbon, hydrogen, nitrogen that comes from distant galaxies is actually the molecules of your body.

There are receptors to these molecules in your immune system, in your gut and in your heart. So when you say, 'I have a gut feeling' or 'my heart is sad' or 'I am bursting with joy,' you're not speaking metaphorically. You're speaking literally.

In the parallel universe the laws of physics are suspended. What goes up does not necessarily come down, a body at rest does not tend to stay at rest and not every action can be counted on to provoke an equal and opposite reaction. Time, 'too, is different. It may run in circles, flow backward, skip about from now to then. The very arrangement of molecules is fluid: Tables can be clocks, faces, flowers.

Physics and those parts of other fields that grow out of physics - chemistry, the structure of big molecules - in those domains, there is a lot of progress. In many other domains, there is very little progress in developing real scientific understanding.

Better biofuels are a really big deal. That means we can precisely engineer the molecules in the fuel chain and optimize them along the way. So, if all goes well, they're going to have designer bugs in warm vats that are eating and digesting sugars to excrete better biofuels. I guess that's better living through bugs.

I thought in my Nobel Lecture I pointed that I was delighted that the Swedish Academy of Science did not quote anything about my current work right now, because the current work that my group is focusing on is actually both the time resolve electrons and possibly x-rays to be able to get the architecture of these molecules, the molecular structures themselves, of very complex biological systems. That's the ultimate goal.

Nature - how, we don't know - has technology that works in every living cell and that depends on every atom being precisely in the right spot. Enzymes are precise down to the last atom. They're molecules. You put the last atom in, and it's done. Nature does things with molecular perfection.

Compare ... the various quantities of the same element contained in the molecule of the free substance and in those of all its different compounds and you will not be able to escape the following law: The different quantities of the same element contained in different molecules are all whole multiples of one and the same quantity, which always being entire, has the right to be called an atom.

Companies are actually much better than governments and other bureaucracies at organizing in a holistically efficient way the extremely complex path from the examination of molecules all the way to the delivery of medicines to patients. Already in the conception and selection of research projects, companies would anticipate all the challenges down the line that they will need to overcome in order to achieve actual health impact. Bureaucratic organizations, by contrast, are notoriously bad at this sort of optimizing.

I build molecules for a living. I can't begin to tell you how difficult that job is. I stand in awe of God because of what he has done through his creation. My faith has been increased through my research. Only a rookie who knows nothing about science would say science takes away from faith. If you really study science, it will bring you closer to God.

While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.

When you buy into any version of fear, it can become your experience because your molecules are intelligent and your energy responds to the predominant feeling in your being. The focus of your mind is exactly what gives the orders to create what you experience.

It has been recognized that hydrogen bonds restrain protein molecules to their native configurations, and I believe that as the methods of structural chemistry are further applied to physiological problems it will be found that the significance of the hydrogen bond for physiology is greater than that of any other single structural feature.

I want to know diverse facts about such things as galaxies or molecules or proteins or insect species. I have an impulse to want to know the little details, which are usually of no significance to non-specialists. I own a dissection microscope, and if there is an insect in the house, I sometimes catch it and look at it under the microscope.

The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.

[My] pictures are about memory and forgetfulness. The evidence is dissolving. Bones crumble; human ash returns to soil; teeth, sandals, hair, bullets, axes disperse into atoms and molecules. Footprints in the snow will be erased by the next storm. The evidence of evil, like the evidence of good, obeys the universal laws of entropy. Heat cools, matter disintegrates, memories fade. If we let them.

As a listener, we're looking for that person who kind of excites the molecules within us - who knows how to tell the story that resonates deeply to our core and almost prompts us into action. Fats Waller has been that person for decades. When people need a lift, sometimes they go to him. I know I do.

If, in the very intense electric field in the neighbourhood of the cathode, the molecules of the gas are dissociated and are split up, not into the ordinary chemical atoms, but into these primordial atoms, which we shall for brevity call corpuscles; and if these corpuscles are charged with electricity and projected from the cathode by the electric field, they would behave exactly like the cathode rays.

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.

Some say that everything that is called a psychical law is nothing but the psychological reflex of physical combinations, which is made up of sensations joined to certain central cerebral processes... It is contradicted by the fact of consciousness itself, which cannot possibly be derived from any physical qualities of material molecules or atoms.

Recognize that the very molecules that make up your body...are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.

The Heart of Gold fled on silently through the night of space, now on conventional photon drive. Its crew of four were ill as ease knowing that they had been brought together not of their own volition or by simple coincidence, but by some curious perversion of physics- as if relationships between people were susceptible to the same laws that governed the relationships between atoms and molecules

Even a vortex is a vortex in something. You can't have a whirlpool without water; and you can't have a vortex without gas, or molecules or atoms or ions or electrons or something, not nothing.

[S]uppose you make a hole in an ordinary evacuated electric light bulb and allow the air molecules to pass in at the rate of 1,000,000 a second, the bulb will become full of air in approximately 100,000,000 years.

Look at your feet. You are standing in the sky. When we think of the sky, we tend to look up, but the sky actually begins at the earth. We walk through it, yell into it, rake leaves, wash the dog, and drive cars in it. We breathe it deep within us. With every breath, we inhale millions of molecules of sky, heat them briefly, and then exhale them back into the world.

There are two ways you can receive energy from your environment: One is molecules bumping against you. That's the air. The other is radiative energy. That's what you're feeling from the sun. When they say "Get out of the sun, out of the heat," the air is the same temperature; it's just you're exposed to sunlight.

A cancer is not simply a lung cancer. It doesn't simply have a certain kind of appearance under the microscope or a certain behavior, but it also has a set of changes in the genes or in the molecules that modify gene behavior that allows us to categorize cancers in ways that is very useful in thinking about new ways to control cancer by prevention and treatment.
