The territory of the ancient Roman Empire covered not only much of Europe, but also parts of North Africa and Asia, as well as numerous islands.

How many people spend the precious moments of their existence that they have been given in human form simply pursuing material goals, while the achievements of generations of scientists, researchers, and inventors continue to shape civilization? Earning money, buying food, fashionable clothes, an ex...
Perhaps no animal in the world has been misunderstood as much as the elephant. These giant herbivores are the largest land animals alive today, but what do we actually know about elephants? Surprisingly little. To begin with, many people mistakenly consider the mammoth to be an ancestor of the eleph...
The world’s most expensive bottle of wine has sold at auction for hundreds of thousands of dollars. Such rare bottles are often treated as collectibles and investments, and some may never be opened.

The Krupp-built Bagger 288, one of the world’s largest bucket-wheel excavators, made headlines when it was transported across Germany to the Hambach open-cast coal mine.

Cats have lived alongside humans for thousands of years, but in the modern era of urban life, people have found them some unusual “jobs.” And cats, for their p...
Holding your breath underwater for as long as possible is a discipline in freediving known as static apnea. In a standard static-apnea attempt, the diver remains still with their face submerged, trying to stay relaxed while holding their breath. Some widely publicized records, however, have been set...
Mount Kailash, also known as Kangrinboqê or Gang Rinpoche, is one of the most sacred mountains in Asia.

Sailing ship — a vessel that uses sails and wind power as a significant means of propulsion. Sailing vessels have existed for thousands of years, from the ships of ancient civilizations to the enormous windjammers of the late 19th and early 20th centuries.

The English Channel separates Great Britain from continental Europe — and for centuries it has been much more than a stretch of water on a map. It has been a playground, a challenge and an irresistible invitation to inventors, adventurers and people who apparently looked at a perfectly good boat and...
The Concorde was more than an airliner. It was a technological statement: a passenger aircraft that could cross the Atlantic at twice the speed of sound, fly at around 60,000 feet and turn a seven- to eight-hour London–New York journey into roughly three and a half hours. For 27 years, Concorde was...

What makes a drug dangerous? Is it the chance of overdose, the risk of addiction, the damage it causes to the body, or the harm it can cause to families and society? There is no single answer. In fact, one of the most famous scientific attempts to answer this question produced some surprisingly cont...
If small cars exist, why shouldn’t there be small 4x4s? They deserve just as much love as large SUVs and off-roaders, while their compact dimensions can make them surprisingly capable on narrow, muddy or snowy roads. And there is another obvious advantage: smaller vehicles can be more economic...

The basketball hoop is 3.05 meters (10 feet) above the floor. For some players, reaching it requires a tremendous jump. For others, simply raising their arms is enough to put the ball within easy reach. Throughout basketball history, the sport has produced some truly extraordinary giants. Here are t...
The press is often called the “fourth estate.” Newspapers report the news, announce events and campaigns, and keep the public informed. They can be just a single sheet of paper or run to hundreds of pages. Some are virtually unknown, while others are recognized around the world. This article looks a...
You can’t surprise anyone with citrus anymore — we add lemon to our tea almost every day, and mandarins are now a year-round fruit rather than something we buy only for New Year’s celebrations. Yet the citrus family includes far more than these familiar fruits. I previously wrote about c...
Some giant dogs can weigh as much as an adult human and, when standing on their hind legs, can even tower over one. The breeds featured in our top 10 are among the largest dogs in the world, with some reaching dimensions that can seem closer to those of a small horse than an ordinary […]
