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.

In the 1920′s the people of Europe feared the future as a dark, despairing place. Despite the loss of over five million Europeans in the Great War, the region was still plagued with the social maladies which had led to the conflict. The humans were maladjusted to the Industrial Age and the changes in labor which it spawned. To make matters worse, both scholars and soothsayers of the day postulated that world’s fluxing economies would congeal into two economic blobs: the Americas would unify into a wealthy super-state in the west, while the east colluded to become an enormous pan-Asian power. Europe would be left economically isolated, with a limited range of climates for farming and fewer resources at hand. Nowhere was the gloom thicker than in Germany where the terms of the Treaty of Versailles led to poverty and hunger for much of the population. It was in the midst of that dark time that an architect named Herman Sörgel devised a plan to preserve Europe through this daunting new worldscape.

Sörgel spent years promoting his scheme to save Europe: the construction of vast hydroelectric dams spanning the Mediterranean. The massive turbines would furnish a surplus of power, and the re-engineered sea would turn the life-hostile Sahara desert into a fertile wetland. In an era when it seemed technology could do no wrong, a considerable segment of the population supported Sörgel’s ambitious plan.

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.

Throughout the Second World War, the town of Hillersleben, Germany was home to one of the Third Reich’s most crucial weapons research centers. At a sprawling facility nestled in the forested hills, a contingent of 150 engineers and physicists developed and evaluated all manner of experimental weapons, a substantial number of which were ultimately adopted by the Nazi war machine.

When Germany surrendered in May 1945, the scientists at Hillersleben were forced to abandon an assortment of death-bringing innovations at various stages of completion. Among these were a rocket-assisted artillery shell which had 50% more range than standard artillery, a 600mm mortar which fired one-ton self-propelled projectiles for up to three and a half miles, a modified Tiger tank which could fire 760-pound rockets up to six miles, and a chain-like projectile made up of small, linked rockets with a range of 100 miles. But the military masterminds’ most sinister ambitions were embodied in their behemoth Sonnengewehr, or “Sun Gun” project– an orbital weapon intended to exact fiery punishment upon the enemies of the Third Reich, forever establishing their dominance over the genetically inferior Untermenschen of the Earth.

Early one Sunday morning in September 1949, throngs of people started to gather around the runway of the Bristol Aeroplane Company factory in the west of England. Curious Bristolians occupied every available vantage point, while workers and their families crowded into special enclosures alongside the airfield. The ten thousand or so bystanders were joined by two hundred and fifty reporters from all corners of the globe, all present in anticipation of an historic event. The message had gone out: “It’s going to be today!”

A huge contraption lay poised on the threshold of the runway: a flying machine far larger than any that the ordinary onlooker would have seen before. With elegant curves and a smooth stressed-metal skin, she looked impressive enough, but there may have been doubts among the spectators regarding the aircraft’s ability to leave the ground. Many had watched the giant plane incessantly track back and forth along the runway over the last two days, with no sign of a take-off. But now the taxi-trials were complete.

At ten o’clock their patience was finally rewarded. To the throaty roar of eight powerful Centaurus piston engines, and the delight of the crowd, the Bristol Brabazon– the largest and most advanced airliner of its day– sped down the runway and took to the air for the very first time. As the graceful behemoth slipped the surly bonds of the Earth, it’s said that the captain, test pilot Bill Pegg, uttered the words: “Good God- it works!” But for all of the splendor surrounding its maiden voyage, the massive aircraft was soon relegated to the scrap heap of aviation history.

Since childhood Dr. Robert Lang has practiced origami. It was the convergence of his intensely creative mind and this ancient Japanese tradition that gave rise to his unique style of origami, which he developed into a renewed art and ultimately a science of practical application.

His intricate paper insect creations were a departure from the standard boats and cranes that have long been the tradition of origami. Over time his works grew more complex, featuring hundreds of folds and multiple pieces of paper, such as a full-scale cuckoo clock. Between his efforts to earn a PhD in applied physics, his job at NASA’s Jet Propulsion laboratory, his eighty technical papers, and his forty-six patents in optoelectronics and lasers, he somehow found time to implement and evolve a number of original origami designs.

The practicality of his scientific research began to influence his origami designs, until the line between the two began to blur. He participated in a project at EASi Engineering to develop complicated crease patterns for airbag folding designs. Lang also worked to design a mesh wire heart support to be folded and implanted in congestive heart failure patients; once inside, it would expand, protecting the heart. His most ambitious project to date, however, is shared with a team at the Lawrence Livermore National Laboratory, with whom he has developed a space telescope – one that is forty times larger than the Hubble and collapsible for space travel through a series of precise origami folds.

Humanity’s home is far from factory-fresh these days. Frankly, the Earth has received its share of scratches and dents, including large asteroid impacts, megavolcanoes, earthquakes, ice ages, and heat waves. It’s to be expected. There are over four billion years on the clock, after all.

Though it has long been clear that Earth 1.0 is in need of an upgrade, it was not until a few years ago that someone began to take the notion seriously. In 2004, at a respected international design exhibition called the Venice Architecture Biennale, a young artist and architect named Christian Waldvogel displayed his plans for total global annihilation and the creation of Earth 2.0.

At the turn of the twentieth century, as the age of automobiles was afoot, the newfangled gasoline-powered internal combustion engine began to reach the limitations of the fuel that fed it. As higher-compression designs were tried, an engine-wrecking condition known as “knock” or “ping” would invariably develop. Though they didn’t know it at the time, the noisy destruction was caused when the increased heat and pressure prompted the air/fuel mixture in the cylinder to detonate all at once as opposed to an orderly burn. In spite of this problem, there was a demand for high-compression designs since they provided increased horsepower and fuel efficiency. The latter was particularly appealing in light of America’s forecasted fuel famine.

In 1921, after a long string of inadequate solutions, a clever but chronically catastrophic chemist named Thomas Midgley developed a fuel additive which eliminated ping problems while increasing fuel efficiency. Though the chemical agent eventually gained worldwide acceptance, it left a rash of psychosis, a trail of bodies, an epidemic of crime, and an irreparably damaged environment in its wake.
