Most stars just fuse hydrogen into helium, but larger stars can fuse helium into other elements. Still larger stars, in turn, fuse those elements into slightly bigger ones, and so on.
Some of the hydrogen in your body comes from the Big Bang, and when you see a kid walking down the street with a helium balloon, you can say, 'There goes some of the primordial universe.'
Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.
If we had a hydrogen economy worldwide, every nation on earth could create its own energy source to support its economy, and the threat of war over diminishing resources would just evaporate.
Second point is no one here could predict or know that Israel was involved or started producing the hydrogen bomb - the most advanced and powerful atomic bomb that can kill millions of people.
The affinity of blood or pure haemoglobins for oxygen is a complex phenomenon, depending upon a number of conditions, the most important of which are temperature and hydrogen ion concentration.
Americans are in need of an all-of-the-above energy approach, and when you think about all-of-the-above, you think about wind, solar, hydrogen, think about all those groovy technologies I really like.
If we were driving pure hydrogen automobiles, that automobile would actually help clean up the air because the air coming out of the exhaust would be cleaner than the air going into the engine intake.
Only in the last week, South Carolina announced that it is seeking to become the U. S. center for hydrogen fuel cells, and BMW revealed that it will power some of its high-end model cars with hydrogen.
Hydrogen holds great promise to meet many of our future energy needs, and it addresses national security and our environmental concerns. Hydrogen is the simplest, most abundant element in the universe.
With sufficient water on the Moon, solar energy can be used to split the water into hydrogen and oxygen. The oxygen is, of course, critical for humans to breathe and the water important for us to drink.
We're not just any star stuff, most of which is humdrum hydrogen and listless helium. Our bodies include fancier ingredients like carbon, oxygen, nitrogen, phosphorous, and a few other herbs and spices.
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?
In organic chemistry, we have learnt to derive from compounds containing only carbon and hydrogen, i.e. from the hydrocarbons, all other types of combinations, such as alcohols, aldehydes, ketones, acids, etc.
Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.
We frequently define an acid or a base as a substance whose aqueous solution gives, respectively, a higher concentration of hydrogen ion or of hydroxide ion than that furnished by pure water. This is a very one sided definition.
My entry into the field of hydrogen came as a great surprise. President Bush of the United States was interested in hydrogen for energy applications, and I was asked to chair a committee on hydrogen for the Department of Energy.
The environmental benefits of hydrogen are also outstanding. When used as an energy source, hydrogen produces no emissions besides water. Zero polluting emissions, an amazing advance over the current sources of energy that we use.
And when these advances are made, hydrogen can fill critical energy needs beyond transportation. Hydrogen can also be used to heat and generate electricity for our homes. The future possibilities of this energy source are enormous.
And I thought about the psychic numbing involved in strategic projections of using hydrogen bombs or nuclear weapons of any kind. And I also thought about ways in which all of us undergo what could be called the numbing of everyday life.
Since hydrogen is a constituent of most of our electrolytic solvents, the definition of an acid or base as a substance which gives up or takes up hydrogen ion would be more general than the one we used before, but it would not be universal.
Something funny certainly happens when palladium and platinum come into contact with hydrogen gas; it's one of the great mysteries still waiting to be solved on the periodic table. But it's quite a leap from 'something funny' to cold fusion.
Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.
Hydrogen peroxide-based bombs were used in the London bombings in 2005; in al Qaeda's foiled plot to attack subways in New York City in 2009 and also in the ISIS-directed Paris attacks in 2015 and the ISIS-directed attacks in Brussels a year later.
For example, a breakthrough in better batteries could supplant hydrogen. Better solar cells could replace or win out in this race to the fuel of the future. Those, I see, as the three big competitors: hydrogen, solar cells and then better batteries.
The strands of the DNA double helix are held together by hydrogen bonding interactions between the complementary base pairs. Heating DNA in solution easily breaks these hydrogen bonds, allowing the two strands to separate - a process called denaturation or melting.
It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.
When ISIS and al Qaeda have attacked or plotted attacks in the West in the past decade or so, they have invariably used hydrogen peroxide-based bombs because acquiring military-grade explosives or dynamite is nearly impossible for would-be terrorists in Western countries.
After earning my Ph.D., I stayed at the Max-Planck Institute as a postdoc, working on laser excitation of Rydberg states of triatomic hydrogen and helium hydride. I also succeeded in analyzing all the emission spectra of helium hydride, which I had discovered during my Ph.D.
Agriculture is now a motorized food industry, the same thing in its essence as the production of corpses in the gas chambers and the extermination camps, the same thing as blockades and the reduction of countries to famine, the same thing as the manufacture of hydrogen bombs.
At first, I was able to use a Bunsen burner attached to my mother's gas stove, but the use of the kitchen as a laboratory came to an abrupt end when a minor explosion involving hydrogen sulphide spattered the newly painted decor and changed the colour from blue to dirty green!
The discovery of deuterium and the marked differences in the physical and chemical properties of hydrogen and deuterium, together with an efficient method for the separation of these isotopes, have opened an interesting field of research in several of the major branches of science.
On the morning of January 17, 1966, a real-life dirty bomb crisis occurred over Palomares, Spain. A Strategic Air Command bomber flying with four armed hydrogen Bombs - with yields between 70 kilotons and 1.45 megatons - collided midair with a refueling tanker over the Spanish countryside.
We are living in a world of fear. The life of man today is corroded and made bitter by fear: fear of the future, fear of the hydrogen bomb, fear of ideologies. Perhaps this fear is a greater danger than the danger itself because it is fear, which drives men to act thoughtlessly, to act dangerously.
In some sense, what you might have suspected from the first day of high-school chemistry is true: The periodic table is a colossal waste of time. Nine out of every 10 atoms in the universe are hydrogen, the first element and the major constituent of stars. The other 10 percent of all atoms are helium.
During the first million years of its existence, mankind survived five apocalypses without succumbing to extinction. It endured the Apocalypse of Steel, the Apocalypse of Hydrogen, the Apocalypse of Serotonin, and both Apocalypses of Water, the second of which occurred despite certain contracts to the contrary.
Three things about water affect almost all of cooking. First are the hydrogen bonds, which is why it has an incredibly high boiling point. Another is that it's a polar molecule, so that it dissolves a lot of things, and there are things that won't mix with it. And then there's how much energy it takes to heat water.
Back in the 1950s, there was a top-secret program code-named SUNTAN being conducted at a top-secret facility called Skunk Works. Its objective? To develop a liquid-hydrogen-powered spy plane. Because liquid hydrogen is incredibly volatile, early experiments were conducted inside a bomb shelter with eight-foot-thick walls.
"God is a spirit." But that does not make him an immaterial being —a being that has no properties in common with matter. The expression "an immaterial being," is a contradiction in terms. Immateriality is only another name for nothing. It is the negative of all existence. A "spirit" is as much matter as oxygen or hydrogen.
The universe starts off with the Big Bang theory, and the first thing that emerged from the Big Bang is essentially hydrogen and then helium. And that's what combusts in stars. Finally, stars implode, and they build heavier elements out of that. And those heavier elements are reconstituted in the heart of other stars, eventually.
I was having a conversation with my father and he was talking about this thing - strangeness and charm. It's actually the name of the two smallest particles that there are when you split the atom, so I wrote a song around it. I even managed to fit the word 'hydrogen' in there. Isn't that a nice thing for scientists to call them though?
There are a few elements - especially platinum and palladium - that have the amazing ability to absorb up to 900 times their own volume in hydrogen gas. To get a sense of the scale there, that's roughly equivalent to a 250-pound man swallowing something the size of a dozen African bull elephants and not gaining an inch on his waistline.
t century, hundreds of millions - and eventually billions - of human beings will transform their buildings into power plants to harvest renewable energies on site, store those energies in the form of hydrogen and share electricity, peer-to-peer, across local, regional, national and continental inter-grids that act much like the Internet.
