The Isle of Doctor Seaborg

Glenn T Seaborg c. 1964
It was the summer of 1936 when Ernest Lawrence, the inventor of the atom-smashing cyclotron, received a visit from Emilio Segrè, a scientific colleague from Italy. Segrè explained that he had come all the way to America to ask a very small favor: He wondered whether Lawrence would part with a few strips of thin metal from an old cyclotron unit. Dr Lawrence was happy to oblige; as far as he was concerned the stuff Segrè sought was mere radioactive trash. He sealed some scraps of the foil in an envelope and mailed it to Segrè's lab in Sicily. Unbeknownst to Lawrence, Segrè was on a surreptitious scientific errand.

At that time the majority of chemical elements had been isolated and added to the periodic table, yet there was an unsightly hole where an element with 43 protons ought to be. Elements with 42 and 44 protons--42molybdenum and 44ruthenium respectively--had been isolated decades earlier, but element 43 was yet to be seen. Considerable accolades awaited whichever scientist could isolate the elusive element, so chemists worldwide were scanning through tons of ores with their spectroscopes, watching for the anticipated pattern.

Upon receiving Dr Lawrence's radioactive mail back in Italy, Segrè and his colleague Carlo Perrier subjected the strips of molybdenum foil to a carefully choreographed succession of bunsen burners, salts, chemicals, and acids. The resulting precipitate confirmed their hypothesis: element 42 was the answer. The radiation in Lawrence's cyclotron had converted a few 42molybdenum atoms into element 43, and one ten-billionth of a gram of the stuff now sat in the bottom of their beaker. They dubbed their plundered discovery “technetium” for the Greek word technetos, meaning "artificial." It was considered to be the first element made by man rather than nature, and its “short” half-life--anywhere from a few nanoseconds to a few million years depending on the isotope--was the reason there’s negligible naturally-occurring technetium left on modern Earth.

In the years since this discovery scientists have employed increasingly sophisticated apparatuses to bang particles together to create and isolate increasingly heavy never-before-seen elements, an effort which continues even today. Most of the obese nuclei beyond 92uranium are too unstable to stay assembled for more than a moment, to the extent that it makes one wonder why researchers expend such time, effort, and expense to fabricate these fickle fragments of matter. But according to our current understanding of quantum mechanics, if we can pack enough protons and neutrons into these husky nuclei we may encounter something astonishing.

Nineteen Seventy Three

On 12 November 1971, in the presidential palace in the Republic of Chile, President Salvador Allende and a British theorist named Stafford Beer engaged in a highly improbable conversation. Beer was a world-renowned cybernetician and Allende was the newly elected leader of the impoverished republic.

Beer, a towering middle-aged man with a long beard, sat face to face with the horn-rimmed, mustachioed, grandfatherly president and spoke at great length in the solemn palace. A translator whispered the substance of Beer's extraordinary proposition into Allende's ear. The brilliant Brit was essentially suggesting that Chile's entire economy--transportation, banking, manufacturing, mining, and more--could all be wired to feed realtime data into a central computer mainframe where specialized cybernetic software could help the country to manage resources, to detect problems before they arise, and to experiment with economic policies on a sophisticated simulator before applying them to reality. With such a pioneering system, Beer suggested, the impoverished Chile could become an exceedingly wealthy nation.

In the early 1970s the scale of Beer's proposed network was unprecedented. One of the largest computer networks of the day was a mere fifteen machines in the US, the military progenitor to the Internet known as ARPANET. Beer was suggesting a network with hundreds or thousands of endpoints. Moreover, the computational complexity of his concept eclipsed even that of the Apollo moon missions, which were still ongoing at that time. After a few hours of conversation President Allende responded to the audacious proposition: Chile must indeed become the world's first cybernetic government, for the good of the people. Work was to start straight away.

Stafford Beer practically ran across the street to share the news with his awaiting technical team, and much celebratory drinking occurred that evening. But the ambitious cybernetic network would never become fully operational if the CIA had anything to say about it.

Pushed to the Limit

On the morning of 15 September 1952, Captain James Robinson Risner sat in the cockpit of an F-86A Sabre and scrutinized the clear azure skies. He was leader of a flight of four Sabres tasked to escort F-84 Thunderjets to bomb the kimchi out of a North Korean chemical factory on the Yuan River. His squinty perseverance paid off when he spotted a flight of enemy jet fighters-- MiG-15s--making a run for his Thunderjets. CPTN Risner's opening salvo hit one MiG so hard it took the canopy off and sent the other 3 MiGs running, but Risner didn't let it end there. The injured enemy took it low, flying hard and dirty along a dry riverbed to escape. Risner and his wingman gave chase, eating the dust and rocks kicked up by the MiG's wash. Risner told "Aces in Combat":

"He was not in very good shape, but he was a great pilot - and he was fighting like a cornered rat!

He chopped the throttle and threw his speed brakes out. I coasted up, afraid that I'd overshoot him. I did a roll over the top of him, and when I came down on the other side, I was right on his wing tip. We were both at Idle with our speed brakes out, just coasting.

He looked over at me, raised his hand, and shook his fist. I thought 'This is like a movie. This can't be happening!' He had on a leather helmet and I could see the stitching in it."

The wily chase took the trio into Chinese airspace. Low altitude and high speed conspired to keep the US pilots from seeing an airfield until they were right on top of it. The MiG pilot must have radioed ahead, however, because the field's anti-aircraft guns were manned and firing.

The MiG darted, desperate to make a landing. Risner waited for his moment and hammered him with the last of his 50 CAL rounds. The MiG slammed into the tarmac and burst into flame. As they turned to hurry out of China and back into compliance with official US policy, the wingman, 1st Lieutenant Joe Logan, took a flak shell to the underside of his plane. The Sabre held together and stayed airborne, but her fuel tank was gutted, and her hydraulic fluid was bleeding out.

Bailing the crippled craft guaranteed Logan's capture, but there was no hope of making it 60 miles over anti-aircraft gun infested territory to the nearest rescue detachment. Risner couldn't desert his friend, so instead he did the only possible thing: he attempted the craziest and most daring rescue maneuver in aviation history.

Night Takes Rook

Please give a warm welcome to our newest author Mr J A Macfarlane. Hip-hip...!

Engineers need to have faith in their designs, but not many would necessarily be confident enough to put their lives at risk just to prove it. It takes a great deal of faith to design a lighthouse for the most dangerous reef in the English Channel, especially when no-one has ever built a lighthouse on the open sea before. It takes rather more to actually build it. And one approaches the shores of hubris when one decides to visit said lighthouse with a massive gale on the way. But when Henry Winstanley, an 18th-century English eccentric, designed and constructed the world’s first open-sea lighthouse on a small and extraordinarily treacherous group of rocks fourteen miles out from Plymouth, he was so confident in his building that he blithely assured all doubters he would be willing to weather the strongest storm within its confines – a boast he had the chance to live up to when he found himself in his lighthouse as the most violent tempest in England’s history approached its shores.

The Enlightenment Guide To Winning The Lottery

This article was written by our shiny new contributor Brendan Mackie.

Condamine/Voltaire
François-Marie Arouet knew how to get into trouble. After a very public scuffle with a nobleman nearly ended in a duel, the young playwright was exiled from Paris, the city where his plays were only just coming into fashion. He lived in dreary England for two whole years before slinking back to France, where he lived in the house of a pharmacist. There he experimented with various potions and poultices, but nothing would cure the vague sense of impotence and dread that dogged him.

Finally in 1729 the gates of Paris were opened to Arouet again, but he was still ill-at-ease. At a dinner party held by the chemist Charles du Fay, Arouet, better known by his pen-name Voltaire, found the cure he had been looking for. He met a brilliant mathematician called Charles Marie De La Condamine, who promised a panacea better than any Voltaire had found at his pharmacist.

It wasn’t medicine--it was money. Condamine had a plan that would make both him and Voltaire more money than he could ever scratch together by writing plays or poems, enough money to allow Voltaire to never have to worry about money again. He would be free to live how he wanted and write what he wanted. The plan was simple. Condamine planned to outsmart luck herself. He was going to arrange to win the lottery.

Steely-Eyed Hydronauts of the Mariana

The crew of the HMS Challenger, 1874
On 21 December 1872, the British naval corvette HMS Challenger sailed from Portsmouth, England on an historic endeavor. Although the sophisticated steam-assisted sailing vessel had been originally constructed as a combat ship, her instruments of war had been recently removed to make room for laboratories, dredging equipment, and measuring apparatuses. She and her crew of 243 sailors and scientists set out on a long, meandering circumnavigation of the globe with orders to catalog the ocean's depth, temperature, salinity, currents, and biology at hundreds of sites--an oceanographic effort far more ambitious than any undertaken before it.

For three and a half long, dreary years the crew spent day after day dredging, measuring, and probing the oceans. Although the data they collected was scientifically indispensable, men were driven to madness by the tedium, and some sixty souls ultimately opted to jump ship rather than take yet another depth measurement or temperature reading. One day in 1875, however, as the crew were "sounding" an area near the Mariana Islands in the western Pacific, the sea swallowed an astonishing 4,575 fathoms (about five miles) of measuring line before the sounding weight reached the floor of the ocean. The bedraggled researchers had discovered an undersea valley which would come to be known as the Challenger Deep. Reaching 6.78 miles at its lowest point, it is now known to be the deepest location on the whole of the Earth. The region is of such immense depth that if Mount Everest were to be set on the sea floor at that location, the mighty mountain's peak would still be under more than a mile of water.

Nothing was known of what organisms and formations might lurk at such depths. Many scientists of the day were convinced that such crevasses must be lifeless places considering the immense pressure, relative cold, total lack of sunlight, and presumed absence of oxygen. It would be almost a century before a handful of inventors and explorers finally resolved to go down there and take a look for themselves.

The Martian Express

On the 5th of February 1974, NASA's plucky Mariner 10 space probe zipped past the planet Venus at over 18,000 miles per hour. Mission scientists took advantage of the opportunity to snap some revealing photos of our sister planet, but the primary purpose of the Venus flyby was to accelerate the probe towards the enigmatic Mercury, a body which had yet to be visited by any Earthly device. The event constituted the first ever gravitational slingshot, successfully sending Mariner 10 to grope the surface of Mercury using its array of sensitive instruments. This validation of the gravity-assist technique put the entire solar system within the practical reach of humanity's probes, and it was used with spectacular success a few years later as Voyagers 1 and 2 toured the outer planets at a brisk 34,000 miles per hour.

One of the more intriguing theories to fall out of the early gravity-assist research was a hypothetical spacecraft called the Cycler, a vehicle which could utilize gravity to cycle between two bodies indefinitely-- Earth and Mars, for instance-- with little or no fuel consumption. Even before the complex orbital mathematics were within the grasp of science, tinkerers speculated that a small fleet of Cyclers might one day provide regular bus service to Mars, toting men and equipment to and from the Red Planet every few months. Though this interplanetary ferry may sound a bit like perpetual-motion poppycock, one of the concept's chief designers and proponents is a man who is intimately familiar with aggressive-yet-successful outer-space endeavors: scientist/astronaut Dr. Buzz Aldrin.

The Remarkable Pneumatic People-Mover

The ventilation shaft at City Hall Park, 1912
On the eighth of February 1912, a small group of officials arrived at City Hall Park on Manhattan's Broadway street. The men gathered at one grassy corner of the park grounds, where a long-neglected iron grating protected the entrance to a seemingly unremarkable ventilation shaft. The heavy, rust-encrusted grille was pried from its resting place, and with lanterns in hand the men descended one by one into the cavity.

About twenty feet below the pavement the group emerged into an eight-foot-wide brickwork tube, the end of which was beyond the immediate reach of the lights. The sturdily-constructed tunnel was a relic from the years following the American Civil War, and it had remained virtually forgotten beneath the streets of New York since its main entrance was sealed sometime around 1880. As the men explored, they found the tunnel in remarkably good condition in spite of its age. When they reached the end of the tube, the men happened upon the wrecked remains of a unique mechanism for transport: a pair of carriages from America's first subway, the experimental and ill-fated Pneumatic Transit System.
