Please give an uncomfortably warm welcome to our newest author, Gustaf Hildebrand.

The meeting had not gone well, the man gloomily reflected as he was driven out of East Berlin. His head was still heavy after a few too many snifters of cognac. The American's ambitious scheme to build a life and career in Moscow had sputtered to an unforeseen halt not unlike a Trabant's two-stroke engine; the only concession the Russians had made was to invite him back for another meeting in two weeks' time. The three KGB representatives he had talked to didn't seem very enthusiastic about his offer to defect from the US Army.

The date was 22 February 1953. It was George Washington's Birthday, a holiday for all American troops stationed in Berlin. The drunken man being shuttled out of East Berlin in a Soviet car was Robert Lee Johnson, a 31-year-old sergeant in the United States Army. Most competent intelligence services would have considered the Army clerk useless, dismissing him as an embittered bureaucrat with a grossly inflated sense of self-worth. Nine years later he would, through a combination of luck and circumstance, become one of the most destructive spies the KGB had ever implanted into the US military.

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.

A simple telegram plunged America into the Great War. The Zimmermann telegram, intercepted by American intelligence in April 1917, revealed Germany’s efforts to encourage Mexico to invade the United States. For a towheaded kid from Arizona named Frank Luke, Jr., and other citizens of the states along the Mexican border, the threat of invasion was real and personal.

Anti-German sentiment swept the nation that spring. Sauerkraut became “Victory Cabbage”, the precursor to Freedom Fries, and suspicion fell on families of German descent such as the Lukes, whose name had been Luecke just a generation before. The immigrants’ son Frank Luke, Jr. had a lot to prove when he joined the Army a few months later.

By the time Luke completed flight training, received his commission, and joined the 27th Aero Squadron in France in July 1918, the surge of American forces onto the Western Front promised a swift end to the war – and the life expectancy of a pursuit pilot at the front was just three weeks. If Frank Luke was going to prove anything, he needed to work fast. In just a few months, he would demonstrate how well he could work under pressure, becoming one of the most decorated flyers of the First World War.

It’s a testament to the strength and versatility of the human brain that anyone with at least half of one tends to assume that their senses give them direct access to objective reality. The truth is less straightforward and much more likely to induce existential crises: the senses do not actually provide the brain with a multifaceted description of the outside world. All that the brain has to work with are imperfect incoming electrical impulses announcing that things are happening. It is then the job of neurons to rapidly interpret these signals as well as they can, and suggest how to react.

This neurological system has done a pretty good job of modelling the world such that the ancestors of modern human beings avoided getting eaten by sabre-toothed tigers before procreating, but the human brain remains relatively easy to fool. Optical illusions, dreams, hallucinations, altered states of consciousness, and the placebo effect are just a handful of familiar cases where what the brain perceives does not correspond to whatever is actually occurring. The formation of a coherent model of the world often relies on imagined components. As it turns out, this pseudo-reality in one’s imagination can be so convincing that it can have unexpected effects on the physical body.

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.

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.

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.
