Elemental shenanigans
At the Start, Hydrogen heaved ho.
Helium laughed. Lithium lay low while Beryllium became bemused.
But Boron bore the burden of all the work yet to be done.
Then Carbon was conceived, and came forth in a manger wrapped in swaddling clothes, surrounded by angelic hosts of other elements, celebrated as the great center-point of history. He would go on to bring myriads of other elements together in peace and productivity, but in latter days was criticized for attaching himself to everybody’s business.
Meanwhile, back at the ranch, good ole Nitrogen nourished all the stuff that came later.
Oxygen got involved and opened a whole new way of life.
Fluorine flew flags of fluorescence for all to see.
Neon knew nothing but nonsense, but was neutral enough to practice non-intervention.
Sodium solved a lot of problems, and he's all over the map with that
Magnesium managed to make itself useful.
Aluminum lightened everybody’s load.
Silicon solidified his/her position, early on in the sands of time, and then later went on to establish a ubiquitous presence in the science of small smart circuits.
Meanwhile Phosphorus flamed along, brightening the path for others.
Sulfur suffered through a lot.
Chlorine clung to just about everything, cleaning house along the way, but has been known to kill when too excited.
Argon atoms are gone until somebody proves their actual existence.
Potassium produces plenteously.
Calcium is known as a great collector of a lot of stuff.
Scandium is scant. Titans use Titanium to tighten up their tridents.Vanadium is very strong, while Chromium captures all the attention. Manganese manages to make good use of itself.
Iron Age innovations initiated innumerable inventions.
Cobalt combines with others to combat corrosion.
Nickel has made itself a necessity.
Copper's a good cop, conducts a lot of traffic.
Amazing Zinc sets up rustless zones wherever it goes. Thank God.
And then there's Gallium; it has the gall to call itself a metal, as if it were a major player along with iron and nickel and all those other big-time movers and shakers.
Germanium is a dope in silicon valley. Arsenic is also a real dope, but reputed to be a pathological killer when let out of his cell. He hides behind old lace.
Selenium periodically illuminates this end of the Table, while Bromine combines medicinally and then resigns.
Krypton is a rare super-phenom found only in old comics of the 1950’s.
Now here's the line-up for the second Period:
Rubidium rules while Strontium drools— radioactivity, that is— 90 times a second, I think, and then renders all those other metalistic johnny-come-lately wannabees as metalla non grata.
If we keep this mining expedition going long enough, we could find lucky ole Silver hiding under the Table.
Along the way we're bound to kick up that perennial also-ran can—Tin— he comes to town and makes the rounds, but always ends up wasting away in a landfill, a real slacker if there ever was one.
And I mean, sure, there are some bright spots on the Periodic Table. There’s the star of the show, gold, hiding down there in the middle of the pack, and glinting in at a clandestine #79. Highly-prized all the time, but he's oh-so-hard to find, unless you’ve got a really big credit line.
Every now and then you may catch sight of that tempereal Mercury, but its hard to pin him down. He never stays in one place long enough to amount to anything. He’s got a really hot temper, but, I'm told, a cold personality.
Down there in the middle of the defensive line there’s the Lead heavyweight-- not very fast, but good on the line-- a good blocker for those fast Uranium backs.
Uranium backs are the stars of the show, you know, forever racking up the big stats. But most of them are real hot shots, and if their temper gets worked up, you can't get rid of 'em. The refs kick 'em out of the game, but they hang around for a long time like they own the place and make trouble for anybody who crosses their path. Don't cross 'em. If they get really fired up they'll go plutonium on ya and that's all she wr

Elements of Life, simplified
Hydrogen initiates life; oxygen proliferates it; carbon gives life something to hold onto.
While helium laughs at the universe, nitrogen fertilizes it.
Sodium makes living things interact; calcium lends them some structure.
Neon, colorful and spritely, excites life, while cousin chlorine cleans up the messes.
Iron puts life to work; silicon makes it smart.
Nickel enables commerce; silver makes the life shine; gold makes it rich.
Uranium steps up the power exponentially, but then it requires maintenance in perpetuity.
Heat it up, and the whole life experiment becomes volatile; anything can happen, and probably will.
Drop in a little arsenic, and life bites the dust. Pay attention.

Defunding H2 from H20
I learn a lot about what's on the cutting edge of scientific research by listening to Ira Flatow on ScienceFriday, NPR. The segment I heard today (8 April 2011) was downright inspiring as the program presented some good possibilities for generating energy from sunlight by experimental technology that could separate of hydrogen and oxygen from water.They call it artificial leaf; its something like synthesized photosynthesis. This ScienceFriday edition is worth a listen.
http://www.sciencefriday.com/program/archives/201104081
Dr. Daniel Nocera of MIT talks with Ira about this very promising technology of using silicon to function in energy-gathering ways simulating what photosynthesis does in natural leaves, only better. Nocera's rap goes like this:
What does a leaf do? It turns photons into electrical current, stores the solar energy while splitting water into hydrogen and oxygen. In this new tech, silicon replaces the leaf. Stored hydrogen produced thereby runs a fuel cell. This silicon system catches the sun as much as a hundred times more efficiently than a leaf.
The real breakthrough is that these researchers are using earth-abundant materials: silicon, cobalt, phosphate and cheap metal. Hence, some practical applications for energy generation are realized; they're building prototypes at MIT, with the experimental apparatus going for days with no drop in productivity. This water-breaking work has propelled progress well beyond the science; now its in the engineering phase.
Ira asks: whats next for commercial viability? Dr. Nocera says they're working toward the apparatus being the workable size of two doors and thus operating effectively. Passing water over silicon and producing energy, but without wires--that's the breakthrough-- making the necessary gases over surface of silicon. Next challenge is engineering a gas collection system, and now they're using regular water instead of something rarer, so that's the real promise of significant improvement.
Dr. Nocera also mentions in the closing comments that people in developing world are less dependent on old technologies than we are; that is something to be aware of. Folks in the developing world are more open to new techs, being less dependent on the old (fossil-fuel) ones.
This is cutting edge; you won't hear about it on fox or hln. That's why I appreciate ScienceFriday, and that's why I appreciate NPR.
Although I do not subscribe to the exclusively materialistic hypotheses through which Ira interprets our cosmological origins, I do appreciate the excellent coverage that he and his staff regularly provide on scientific frontiers.
And my appreciation extends beyond the ScienceFriday crew, to NPR generally, which is an informative aural venue through which we Americans can garner fuller understanding of our life on this finite planet as it exists today. National Public Radio is a place in broadcast space where we can hear, and participate in, real disscussions about relevant, timely issues. A little "liberal" perhaps, but its more productive, I think, than listening to some self-made mouthpiece who pontificates through a microphone and insults callers who disagree.
As a supporter of public radio, I hope to see ScienceFriday and all the other NPR programs continue. If the Repubs, of which I am one, succeed in cutting the funds for public broadcasting, I do not see that as an insurmountable obstacle for its continuance. I plan to continue my financial support. I truly believe that the excellence in journalism and educative programming supplied therein will find adequate means to prosper in the competitive world of commercial media--and without compromising their high journalistic and first-amendment standards.
If our Congress is inclined to consider cutting NPR out of the federal funding trough, I suggest that they defund Planned Parenthood instead, and then appropriate that money that would have otherwise aborted feti to promote growth--growth in public comprehension of the issues that define our existence in 21st-century America.
There's no sense in aborting feti when we will have dire need, in the future, for young working citizens to support our expanding Medicare demands and our waning energies.
