Scientists and supercomputers have amplified our ability to look ahead. For decades, experts have warned us that human numbers, technology, hyper-consumption and a global economy are altering the chemical, geological, and biological properties of the biosphere.
Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).
Chemical propulsion is obsolete to go anywhere other than the moon. Three days - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then spend whatever length of time we want to spend and return when we want to come home.
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.
Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions.
Syria is important because it lies at the heart of a region critical to U.S. security, a region that is home to friends and partners and one of our closest allies. It is important because the Syrian regime possesses stores of chemical weapons that they have recently used on a large scale and that we cannot allow to fall into terrorists' hands.
We the chefs have a responsibility to learn about the chemical makeup of food!

I'm sure a majority of farmers do their best to follow safe practices, to read carefully chemical labels, to follow the law, and to try and ensure that they are making both safe and profitable decisions for their business.
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.
Plants can't very well defend themselves by their behavior, so they resort to chemical warfare, and plants are saturated with toxins and irritants to deter creatures like us who want to eat them.
Our sexual lives are maintained by the shadow side and the light side, so the more we can understand and embrace enlightenment, the less need there is for chemical enhancement.
Computer photography won't be photography as we know it. I think photography will always be chemical.
When we're talking about technology that involves weapons of mass destruction, nuclear, chemical or biological weapons, there has to be an element of preemption.
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.
We need the UN, to deal with the threats to our common security from nuclear, chemical and biological weapons, not only in the case of Iraq. They must be tackled by the international community together, by strengthening conventions, treaties and agreements.
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.
What we know from World War I is that some of our troops had acute symptoms of exposure to chemicals, had bad health and died because of chemical exposure in World War I.
The relationship between 'My Chemical Romance' and Michael Pedicone is over. He was caught red-handed stealing from the band and confessed to police after our show last night in Auburn, Washington. We are heartbroken and sick to our stomachs over this entire situation.
Most Americans will be horrified that President Obama is compromising our deterrent to chemical and biological attacks on this country. Our allies will also be troubled by his aspiration to eliminate U.S. tactical nuclear weapons in Europe.
The threat from Saddam Hussein and weapons of mass destruction - chemical, biological, potentially nuclear weapons capability - that threat is real.
George W. Bush and Tony Blair had to convince the world that Saddam Hussein represented an imminent threat. Tony Blair lied when he claimed that Iraq could launch a chemical or biological attack within 45 minutes.
And they will tell you unequivocally that if we have a chemical or biological attack or a nuclear attack anywhere in this country, they are unprepared to deal with it today, and that is of high urgency.
This success led my theoretical group to the chemical reactivity theory, extending more and more widely the range of compound and reactions that were discussed.
When we faced a possibility here in New York of chemical and biological attack, three days after September 11, I called in all of the experts, academic experts, Nobel Prize laureates, and doctors who had dealt with anthrax, doctors who had dealt with various forms of chemical and biological attack.
Saddam Hussein 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.
Nowadays, however, we recognize that simultaneously with the typical case of a chemical reaction a typical case of catalytic effect had been studied which constitutes a limiting case.
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 had to find a diet that would kick me back into dating shape, because I know that I can't date at size 8. I have to date at size 2. And it's just a fact of nature. Go get your injections and your chemical peels. You gotta look good to attract a man.
I consider nature a vast chemical laboratory in which all kinds of composition and decompositions are formed.
Cooking is one of the strongest ceremonies for life. When recipes are put together, the kitchen is a chemical laboratory involving air, fire, water and the earth. This is what gives value to humans and elevates their spiritual qualities. If you take a frozen box and stick it in the microwave, you become connected to the factory.
No one doubts that innocent men, women and children have been the victims of chemical weapons attacks in Syria. And there's no doubt who is responsible for this heinous use of chemical weapons in Syria: the Syrian regime.
One letter to bin Laden reveals that al Qaeda was working on chemical and biological weapons in Iran.
I also became interested in chemistry and gradually accumulated enough test tubes and other glassware to do chemical experiments, using small quantities of chemicals purchased from a pharmacy supply house.
