The Fascinating Tale of Measuring Light and Upending Our Understanding of the Universe

It is by far the most famous equation in the history of science – and one of the shortest: E=mc2. Derived by Albert Einstein in 1905, the equation describes the relationship between mass and energy, stating that the total energy contained in a given piece of matter is equal to its mass times the speed of light squared. Given that […]

Do Spaceship Escape Pods Actually Exist in Real Life?

In the 1969 science fiction film Marooned, a trio of astronauts manning an experimental space station attempt to return to earth, only for their spacecraft’s main engine to fail. Without sufficient fuel either to initiate reentry or return to the space station, the astronauts find themselves – well, marooned – in orbit, doomed to slowly suffocate unless some bold rescue […]

The Fascinating Story of One of the Most Elegant and Powerful Experiments in the History of Science

On March 31, 1851, a crowd of curious Parisians gathered at the Pantheon to witness a historic scientific demonstration. In the centre of the building, directly beneath its towering dome, they found a deceptively simple piece of equipment: a 28-kilogram brass-coated lead sphere, suspended from the building’s dome by a 67-metre-long wire. Beneath this was placed a wooden platform covered […]

What is Up with Space Food?

If your parents ever took you to a science museum or planetarium as a child, you likely spent much of your visit in the gift shop, begging them to buy you one of the hundreds of shiny – and purportedly “educational” – items on offer. And most irresistible of all was undoubtedly “astronaut food”: shiny foil packets of freeze-dried strawberries […]

What Does the “Octane Rating” of Fuel Actually Mean?

Ah, the joys of vehicle ownership! Traffic jams! Construction! Costly insurance! Speed traps! Searching endlessly for parking! Having the check engine light come on just as you were about to buy that new game system and having the mechanic charge you thousands of dollars for parts and labour… and, of course, the greatest joy of all: that weekly soul-crushing, wallet-emptying […]

Why Do We Grow Old?

Ah, immortality, previously only for the gods and individuals with a fetish for chopping each other’s heads off. In more modern times, science is coming closer and closer to both identifying the tapestry of things that cause humans to grow old, and slowly but surely taking the first steps into finding ways to delay and even reverse this process for […]

How Does Nuclear Waste Disposal Work?

31 countries currently use some form of nuclear power, with the 455 currently operational reactors generating some 393,000 Megawatts of electricity – nearly 20% of the world’s total energy production. Despite high-profile disasters such as Chernobyl, Three-Mile-Island, and Fukushima, nuclear power is actually among the safest and cleaner forms of electricity generation, placing dead-last in terms of deaths per kilowatt-hour […]

The Mysterious and Fascinating World of ‘Numbers Stations’

Shortwave radio signals, which occupy the radio frequency band between 3 and 30 megahertz, have the unique ability to bounce or “skip” off the earth’s ionosphere, allowing them to propagate over vast distances. This has attracted a devoted international community of shortwave radio enthusiasts, who exploit the unique properties of the medium to listen to and communicate with shortwave stations […]

How Does Stealth Technology Actually Work?

At precisely 3 in the morning on January 17, 1991, a series of explosions rocked the Iraqi capital of Baghdad. The explosions were exact and devastating, destroying Iraqi military radars, command bunkers, and communications hubs with surgical precision. Immediately, Iraq’s aerial defence system sprang into action, its 3,000 anti-aircraft guns saturating the air with explosive shells. But the 60 surface-to-air […]

Space Religion

On Christmas Eve, 1968, nearly a billion people sat glued to their radios and television sets as the crew of Apollo 8 entered orbit around the moon. For three days the world had followed the pioneering mission three live television broadcasts, and they now waited eagerly to hear the historic words of the first humans to reach another world. Then, […]

Do Humans Have Pheromones?

Paul A. asks: Is there really such a thing as human pheromones? Insects, such as the male silk worm using the pheromone Bombykol have long been known to attract mates through pheromones. Moving over to the one humped camel, also known as the Arabian camel and dromedary, of all their adaptations, the grossest is probably the male dromedary’s proclivity to […]

The Curious Case of the People With Split Brains

In late 1961, Drs. Philip Vogel and Joseph Bogen, neurosurgeons at the California College of Medicine in Los Angeles, were preparing to carry out a radical new procedure. The patients under their care suffered from severe epilepsy, which despite their doctors’ best efforts had resisted all attempts at conventional treatment.  One such patient, a 48-year-old former paratrooper identified in medical […]

Tesla, Hollywood, and Inventing the Drone

Drones. Whether raining down death and destruction on the battlefield, capturing sweet snowboarding and mountain bike moves for YouTube, helping farmers inspect their fields, or driving aviation authorities mad by wandering into controlled airspace, drones seem to be just about everywhere these days. Using the latest in remote control and automatic guidance technology, drones – more properly known as Unmanned […]
