The ITER Project
Years from now—maybe in a decade, maybe sooner—if all goes according to plan, the most complex machine ever built will be switched on in an Alpine forest in the South of France. The machine, called the International Thermonuclear Experimental Reactor, or iter, will stand a hundred feet tall, and it will weigh twenty-three thousand tons—more than twice the weight of the Eiffel Tower. At its core, densely packed high-precision equipment will encase a cavernous vacuum chamber, in which a s...Description of a multi-national effort to produce a fusion reactor. Something some refer to as a "non-optional" technology for the human race to survive.

Survival of the Stable
Darwin's 'survival of the fittest' is really a special case of a more general
law of survival of the stable. The universe is populated by stable things.
A stable thing is a collection of atoms that is permanent enough or
common enough to deserve a name. It may be a unique collection of
atoms, such as the Matterhorn, that lasts long enough to be worth
naming. Or it may be a class of entities, such as rain drops, that come
into existence at a sufficiently high rate to deserve a collective name,...One of the characteristics of a successful species is stability.

Infinite Creativity was Stored in Hydrogen Atoms
Once the matter created by the Big Bang cooled sufficiently, the universe consisted of a vast cloud of hydrogen atom consisting of a single proton surrounded by a single electron—along with a smattering of slightly heavier elements, including helium (with two protons) and lithium (with three). The universe at that time was about the most boring place imaginable. It consisted of nothing but disembodied atoms drifting through space and the radiation left over from the Big Bang. Yet the potent...From this simple unit, everything in the Universe came about.

The Power of Chemical and Nuclear Energy
New sources of power ... will surely be discovered. Nuclear energy is incomparably greater than the molecular energy we use today. The coal a man can get in a day can easily do five hundred times as much work as himself. Nuclear energy is at least one million times more powerful still. If the hydrogen atoms in a pound of water could be prevailed upon to combine and form helium, they would suffice to drive a thousand-horsepower engine for a whole year. If the electrons, those tiny planets of t...Folksonomies: energy

Churchill recognizes the power of coal and predicts the awesome power of nuclear energy.

Seeing How Species Arise is Similar to Understanding Star...
The way we discovered how species arise resembles the way
astronomers discovered how stars “evolve” over time. Both processes
occur too slowly for us to see them happening over our lifetime. But we
can still understand how they work by finding snapshots of the process
at different evolutionary stages and putting these snapshots together
into a conceptual movie. For stars, astronomers saw dispersed clouds
of matter (“star nurseries”) in galaxies. Elsewhere they saw those clouds condens...Just as astronomers search the skies for stars in varying stages of life, biologists look for species in varying degrees development.
