The Mechanical Battery
In principle, a flywheel is nothing more than a wheel on an axle which stores and regulates energy by spinning continuously. The device is one of humanity’s oldest and most familiar technologies: it was in the potter’s wheel six thousand years ago, as a stone tablet with enough mass to rotate smoothly between kicks of a foot pedal; it was an essential component in the great machines that brought on the industrial revolution; and today it’s under the hood of every automobile on the road, performing the same function it has for millennia—now regulating the strokes of pistons rather than the strokes of a potter’s foot.
Ongoing research, however, suggests that humanity has yet to seize the true potential of the flywheel. When spun up to very high speeds, a flywheel becomes a reservoir for a massive amount of kinetic energy, which can be stored or drawn back out at will. It becomes, in effect, an electromechanical battery. Read the rest of this Article ▶
The Gravity Express
Hooke’s calculations showed that if the technology could be developed to bore such holes through the Earth, a vehicle with sufficiently reduced friction could use such a tunnel to travel to another point anywhere on the on Earth within three quarters of an hour, regardless of distance. Even more amazingly, the vehicle would require negligible fuel. The concept is known as the Gravity Train, and though it seems inconceivably difficult to construct, it has received some serious scientific attention and research in the intervening centuries.

Evolving Universes
Evolutionists and naturalists have long observed Earth’s “natural selection” where most creatures create offspring with slightly different characteristics than their own. Those with characteristics better suited to the environment will thrive, procreate, and pass on their heritage; whereas offspring less suited will wither, reproduce less, and their traits will fade and vanish.
Theoretical physicist Lee Smolin looked at the simple, functional elegance found in the the theory of natural selection, and thought that maybe such a concept could be applied on a universal scale. Thus the theory of Cosmological Natural Selection was born. Read the rest of this Short ▶
Baseball and the Physicists
Very rarely do these scientists, mostly physicists, offer practical advice for players to take into the field, but they do come up with some interesting observations. And almost all of them have to do with the baseball-bat “collision sequence.” Read the rest of this Article ▶
The Hutchison Effect
What the H-Effect is purported to do is nothing short of extraordinary. It is said to cause objects to defy gravity, cause metal to spontaneously fracture, cause dissimilar materials to fuse (such as metal and wood), and other strange phenomena. Hutchison has captured the effect on video many times, and claims to have demonstrated it for scientists from U.S. Army intelligence. But the claims are mired in doubt because the effect is not reproducible, even by the discoverer himself. Read the rest of this Short ▶
Skipping Bombs Like Stones
Finding a method for destroying the dams, however, proved difficult. Anything but a direct hit with a normal bomb would not do enough damage to break the dam, and bombs were not accurate enough at the time. A bomb powerful enough to destroy a dam via a direct hit would be too heavy for any conventional airplane to carry. On top of that, the dams were protected underwater by torpedo nets, so the only possible way to hit the dam would be against its wall, near the surface of the water. There were no bombs that could get around these problems. The British military found this dilemma unsolvable.
Then along came Barnes Wallis, who invented a bomb that capitalized on the same physics as skipping a stone over water. Read the rest of this Short ▶
Prepare for Ludicrous Speed
Heim’s ideas described a “hyperdrive” which would locally modify the constants of nature in such a way that a vehicle would be allowed to travel at immense speeds, possibly faster than the speed of light. Such a propulsion system could theoretically reach Mars in under five hours, and neighboring stars within a few months.
But shortly after he announced his theory, Heim went into isolation, and took his theories and formulas with him. It would be years before his theories again resurfaced, but when they did, they attracted the attention of NASA, the U.S. military, and the Department of Energy. Read the rest of this Article ▶
The Physics of Quicksand
Quicksand is one of the staple environmental hazards in cartoonish low-budget movies, where it has been known to quickly swallow unwitting persons as they wander through jungles and deserts. It is usually represented as a deep pool of sandy goo which blends in with its surroundings, lying in wait to slowly suck in anyone who attempts to traverse it. Barring any nearby vines or branch-wielding comrades, the victim will slowly sink until completely submerged. Unsurprisingly, real quicksand is pretty tame in comparison to Hollywood’s depiction, but traditional quicksand does have an evil cousin that would pose a grave threat to anyone who might stumble upon it… if it exists.
