We're exposed and carry in our bodies multiple chemicals, and we have to understand how they interact. Both how they individually interact and the thousands of effects they can produce when they interact with the receptors that run our bodies.
I listen to everything. I love The Chemical Brothers.
I find it hilarious that there are academics who try to analyse chemical changes in the brains of students while exposing them to gags.
My Chemical Romance is done. But it can never die.
I've always seen My Chemical Romance as the band that would have represented who me and my friends were in high school, and the band that we didn't have to represent us - the kids that wore black - back then.
Short cycle business are being impacted by credit, and are being impacted by gasoline prices, food, distribution businesses, chemical business.
The more natural the charcoal, the better your food will taste. Rather than briquettes, use lump charcoal, which is is all-natural. Lump charcoal will cause your grill to get much hotter than briquettes. Also, briquettes have chemical filler which holds saw dust together and can change the taste of the food.
Those of us who work in this field see a developing potential for nearly a total control of human emotional status, mental functioning, and will to act. These human phenomena can be started, stopped or eliminated by the use of various types of chemical substances. What we can produce with our science now will affect the entire society." A "utopia" could be found - providing "a sense of stability and certainty, whether realistic or not.
Life evolved under conditions of light and darkness, light and then darkness. And so plants and animals developed their own internal clocks so that they would be ready for these changes in light. These are chemical clocks, and they're found in every known being that has two or more cells and in some that only have one cell.
Diet Coke does not contain nasty chemicals. It contains lovely and delicious carbonation, caffeine, and aspartame. What's unnatural about that?
[About reading Rachel Carson's Silent Spring, age 14, in the back seat of his parents' sedan. I almost threw up. I got physically ill when I learned that ospreys and peregrine falcons weren't raising chicks because of what people were spraying on bugs at their farms and lawns. This was the first time I learned that humans could impact the environment with chemicals. [That a corporation would create a product that didn't operate as advertised] was shocking in a way we weren't inured to.
From my studies of genetics and neuroscience I have come to believe that people fall into four broad personality types - each influenced by a different brain chemical: I call them the Explorer, Builder, Director, and Negotiator.
It turns out that Molly wasn't her mother's daughter in that respect. Charity was like the MacGuyver of the kitchen. She could whip up a five-course meal for twelve from an egg, two spaghetti noodles, some household chemicals, and a stick of chewing gum. Molly ... Molly once burned my egg. My boiled egg. I don't know how.
No one can believe I might have a brain. Because I'm really tall, I'm really blonde, I have big muscles, and kill people for a living. There you go. If anybody's going to be assumed to be stupid, it's me. I don't know what my IQ score is, but I did study for five years at college. And I'm proud of my chemical engineering degree. I haven't done anything with it, but it's a card up your sleeve for later in life. It's nice to have, just in case.
IT is now reaching out to fuels and chemicals, energy and clean tech, rockets, all kinds of bizarre industries that formerly didn’t face much competition.
The execution of William Bonin was not the traditional gas chamber of the past. That has been ruled cruel and unusual. Instead, we have something that seems very kind and benign and technical; the injection of chemicals, Nazi-style.
Every one of you sitting here today is carrying at least 500 measurable chemicals in your body that were never in anybody's body before the 1920s... We have dusted the globe with man-made chemicals that can undermine the development of the brain and behavior, and the endocrine, immune and reproductive systems, vital systems that assure perpetuity... Everyone is exposed.
In fact, it seems that present-day science, with one sweeping step back across millions of centuries, has succeeded in bearing witness to that primordial 'Fiat lux' Let there be light uttered at the moment when, along with matter, there burst forth from nothing a sea of light and radiation, while the particles of the chemical elements split and formed into millions of galaxies ... Hence, creation took place in time, therefore, there is a Creator, God exists!
I believe the proliferation of weapons of mass destruction presents the greatest threat that the world has ever known. We are finding more and more countries who are acquiring technology - not only missile technology - and are developing chemical weapons and biological weapons capabilities to be used in theater and also on a long range basis. So I think that is perhaps the greatest threat that any of us will face in the coming years.
But in fact, when you try to model that on a computer you find that because of the very structure of matter and of the chemical bonds that are the basis of every organism, evolution is not random at all. It will tend to follow certain paths.
If a chemical drug like Viagra is accepted by society and by the world to ignite desire, then what is the problem with my audio-visual drug called cinema which ignites desire? Both are basically doing the same thing!
The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself made up of several units into a selfcontained whole.
'Tis a superstition to insist on a special diet. All is made at last of the same chemical atoms.
It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system.
I think the facts leave no doubt that the very mightiest among the chemical forces are of electric origin. The atoms cling to their electric charges, and opposite electric charges cling to each other.
For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.
By recognizing that the chemical atom is composed of single separable electric quanta, humanity has taken a great step forward in the investigation of the natural world.
With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms.
Within a hundred years of physical and chemical science, men will know what the atom is. It is my belief when science reaches this stage, God will come down to earth with His big ring of keys and will say to humanity, 'Gentlemen, it is closing time.'
Football tactics are rapidly becoming as complicated as the chemical formula for splitting the atom.
Pauling was shocked by the freedom with which the X-ray crystallographers of the time, including particularly Astbury, played with the intimate chemical structure of their models. They seemed to think that if the atoms were arranged in the right order and about the right distance apart, that was all that mattered, that no further restrictions need to be put on them.
Every chemical substance, whether natural or artificial, falls into one of two major categories, according to the spatial characteristic of its form. The distinction is between those substances that have a plane of symmetry and those that do not. The former belong to the mineral, the latter to the living world.
We speak erroneously of "artificial" materials, "synthetics", and so forth. The basis for this erroneous terminology is the notion that Nature has made certain things which we call natural, and everything else is "man-made", ergo artificial. But what one learns in chemistry is that Nature wrote all the rules of structuring; man does not invent chemical structuring rules; he only discovers the rules. All the chemist can do is find out what Nature permits, and any substances that are thus developed or discovered are inherently natural. It is very important to remember that.
Land mines, torture equipment, cluster bombs, chemical weapons are weapons designed to inflict pain and death on human beings. Most victims are civilians, women and children. How can arms manufacturers, weapons designers, plant managers, politicians, who have families of their own whom they love, be so insensitive when it comes to the suffering of other human beings?
We can decide that the presence of cancer-causing substances in our air, water, and food is too expensive. A 2009 study, for example, has found that coal miners in Appalachia costs the region five times more in premature deaths, including from cancer, than it provides to the region in jobs, taxes, and economic benefits. In California, the production and use of hazardous chemicals cost the state $2.6 billion in 2004 alone in lost wages and health-care expenses to treat workers and children with pollution-linked diseases.
Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives. - Dr. Carl Sagan
We may lay it down as an incontestible axiom, that, in all the operations of art and nature, nothing is created; an equal quantity of matter exists both before and after the experiment; the quality and quantity of the elements remain precisely the same; and nothing takes place beyond changes and modifications in the combination of these elements. Upon this principle the whole art of performing chemical experiments depends: We must always suppose an exact equality between the elements of the body examined and those of the products of its analysis.
For decades, people have known the chemical-propulsion approach to space travel is really not going to get us that far. Chemical propulsion is essentially like the horse-and-cart approach to the exploration of the American West, instead of the steamboat or the railroad.
Biologists have long attempted by chemical means to induce in higher organisms predictable and specific changes which thereafter could be transmitted in series as hereditary characters. Among microorganisms the most striking example of inheritable and specific alterations in cell structure and function that can be experimentally induced and are reproducible under well defined and adequately controlled conditions is the transformation of specific types of Pneumococcus.
Disco satisfied social as well as musical needs. Disco people got to dress up all the time and go to places ... where everybody sort of 'looked good' - and later, after an evening of chemical alteration, everybody looked even better, and the next thing they knew, they were getting The Blox Job. Punk, in the late seventies, purported to be a rebellion against this sort of silly behavior. Maniac bands started thrashing away in dingy little places with no decor, developing their own silly behavior. ... New wave evolved from punk, basically, by sterilizing its own safety pin.
Cellular pathology is not an end if one cannot see any alteration in the cell. Chemistry brings the clarification of living processes nearer than does anatomy. Each anatomical change must have been preceded by a chemical one.
Our soldiers in another area were attacked chemically. Our soldiers - they went to the hospital as casualties because of chemical weapons, but in the area where they said the government used chemical weapons, we only had video and we only have pictures and allegations. We're not there ; our forces, our police, our institutions don't exist there. How can you talk about what happened if you don't have evidence ?
Today, about 40 percent of America's carbon pollution comes from our power plants. There are no federal limits to the amount those plants can pump into the air. None. We limit the amount of toxic chemicals like mercury, and sulfur, and arsenic in our air and water, but power plants can dump as much carbon pollution into our atmosphere as they want. It's not smart, it's not right, it's not safe, and I determined it needs to stop.
The advances of biology during the past 20 years have been breathtaking, particularly in cracking the mystery of heredity. Nevertheless, the greatest and most difficult problems still lie ahead. The discoveries of the 1970's about the chemical roots of memory in nerve cells or the basis of learning, about the complex behavior of man and animals, the nature of growth, development, disease and aging will be at least as fundamental and spectacular as those of the recent past.
If the Bush Administration cannot ensure Americans that they will be safe from the flu, how will they protect our country against a possible bio-terror or chemical attack? The American people deserve better.
This would be a very good moment to institute a call for imposing the Chemical Weapons Convention on the Middle East. The actual Chemical Weapons Convention. Not the version that [Barack] Obama presented in his address to the nation and that media commentators repeat. What he said is that the convention bars the use of chemical weapons. He knows better. And so do the commentators. The Chemical Weapons Convention calls for banning the production, storage and use of chemical weapons, not just the use. So why omit production and storage?
There's no question that Saddam Hussein is a threat Yes, he has chemical and biological weapons. He's had those for a long time. But the United States right now is on a very much different defensive posture than we were before September 11th of 2001 He is, as far as we know, actively pursuing nuclear capabilities, though he doesn't have nuclear warheads yet. If he were to acquire nuclear weapons, I think our friends in the region would face greatly increased risks as would we.
It is vitally important that we can continue to say, with absolute conviction, that organic farming delivers the highest quality, best-tasting food, produced without artificial chemicals or genetic modification, and with respect for animal welfare and the environment, while helping to maintain the landscape and rural communities.
Fight fire with fire. If you must have bores, always put them together or at the same table ... bores have an effervescent chemical reaction on one another at a party. They invariably have a marvelous time trading banalities in the absence of competition. Clichés roll trippingly off the tongue like sparkling epigrams and trite observations acquire depth sinking into receptive minds.
