Falling in love is a chemical reaction. But it wears off in a year.
Through the continued accumulation of detailed and reliable knowledge about elementary reactions, we will be in a better position to understand, predict and control many time-dependent macroscopic chemical processes which are important in nature or to human society.
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.
Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids as livestock, launch armies into wars, use chemical sprays to alarm and confuse enemies, capture slaves... They do everything but watch television.
The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable; the chain of evil it initiates not only in the world that must support life but in living tissues is for the most part irreversible. In this now universal contamination of the environment, chemicals are the sinister and little-recognized partners of radiation in changing the very nature of the world-the very nature of its life.
It is time to end the discrimination against people who need treatment for chemical addiction. It is time for Congress to deal with our Nation's number one public health problem.
I think that we are already making steps toward mapping out the brain so we can identify the chemical patterns that create and store memory.
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.
In the case of Iraq, notwithstanding the violence there at the moment, the very fact that a hideous regime - responsible for genocide, for the use of chemical and biological weapons, aggression against two neighbors - has been removed in itself is a positive development.
A neighborhood friend showed me how it was possible to go to a camera shop and pick up chemicals for pennies... literally... and develop your own film and make prints.
For me, first, it's finding quiet in my life - and I do that through yoga and meditation. It's also been a matter of changing the way I eat, because I think what we eat can inform who we are; food is a chemical and a drug to a certain extent.
He has systematically violated, over the course of the past 11 years, every significant UN resolution that has demanded that he disarm and destroy his chemical and biological weapons, and any nuclear capacity. This he has refused to do.
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.
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.
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.
The inspections started in 1991, right after the Gulf War. One of the conditions for the ceasefire was that Iraq had to do away with all of its weapons of mass destruction - biological, chemical and nuclear weapons and long-range missiles.
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.
I studied chemical engineering. I was a good student, but these were the hard times of the depression, my scholarship came to an end, and it was necessary to work to supplement the family income.
We also have to stop the flow of precursor chemicals that meth cooks use to boil up this poison.
Every chemical reaction has a transition state.
What surprises me, what amazes me, is that it seems the military people were expecting to stumble on large quantities of gas, chemical weapons and biological weapons.
After all, the universe required ten billion years of evolution before life was even possible; the evolution of the stars and the evolving of new chemical elements in the nuclear furnaces of the stars were indispensable prerequisites for the generation of life.
Cult recruiting methods based on dosing victims with the brain chemicals released during capture bonding would make cults even more of a problem than they are now.
Loads of chemicals and hazardous wastes have been introduced into the atmosphere that didn't even exist in 1948. The environmental condition of the planet is far worse than it was 42 years ago.
This I conceive to be the chemical function of humor: to change the character of our thought.
