In imaginings of the future in ﬁlm and television such as Futurama or Alien, people are easily frozen for hundreds of years or placed into a state of “hypersleep” during ﬂights to distant stars. Although these stories are still ﬁctitious, somewhere on Earth several hundreds of frozen bodies are just waiting to be discovered. How does this freezing process work, and might we be able to one day bring them back to life?
Not too long ago, we were making plans for the upcoming year. Now, it’s time to realize them. The key to achieving our goals is a bullet journal — a hybrid of a daily planner and personal diary.
Sometimes we do something just because everyone else around us is doing it. We buy a new video game because our friends are obsessed with it or we make a TikTok account to make sure we understand our classmates’ references. Or we suffer through a dull, drawn-out movie that everyone else, of course, has already seen and loved. What is this strange force that makes us copy the actions of those around us?
Many centuries ago, riding waves was a favorite pastime of the natives of Polynesia, and today it’s a professional sport that’s even included in the Olympic games. Over hundreds of years, the boards and styles of surfing have changed, but there is still a sense of magic when you see a wave appear out of nowhere and a person hop on, carving a line in the water that immediately disappears into turbulent foam. However, behind any “magic” are the laws of physics, and surfing is no exception. Here, we’ll tell you all about where the waves come from and how surfers manage to “saddle” them.
The birthplace of traffic signs is thought to be Paris. In 1908, the first World Road Congress was held here, and the very first traffic signs were adopted: “bump,” “curve,” “intersection,” and “grade-level railroad crossing.” Gradually, the number of traffic signs increased, and today there are many dozens of different systems for their use.
It is a well-accepted practice to represent the number equivalent to the ratio of the circumference of a circle to its diameter with the Greek letter π. Perhaps this is the most famous mathematical letter — after all, it’s used by architects, physicists, astronomists, chemists, biologists, and many others.
On January 28, 1887, the cavalry detachment guarding the banks of the Yellowstone River against the Great Sioux Nation was covered by an amazing snowfall. The weather had been warm, so one of the falling snowflakes quickly drew the attention of the General — at almost 15 inches in size, it is still thought to be the largest snowflake ever seen by humankind.
How can anyone say with certainty that we’ve never been visited by aliens from outer space? Thousands of meteorites have, at some point, made their way through space to fall literally at our feet. This month, we’re going to find out where humans discovered these extraterrestrial rocks, what threatens them today, and why just 200 years ago scientists didn’t even believe in their existence.
Most of the people on Earth currently live in cities, but many of them don’t realize that the urban climate they experience is different than outside the city. Why does this happen, and what consequences can it have for city populations?
It was once considered a fancy dish and cost six times more than a serving of fresh noodles. The story of its dramatic decline in status — from a luxury item to a student’s budget food — is very curious indeed.
