Even those that do not particularly care for math will agree that pi, or “π," is fascinating. The numerical constant — defined as the ratio of the circumference of a circle to its diameter— is recognized by most as 3.14. However, Pi is an irrational number. This means it can't be written as a fraction. Instead, it is infinitely long and never forms a repeating pattern. While individuals attempt to break records by memorizing pi's decimal points, scientists strive to find its most accurate value using new algorithms and powerful computers....

Clothing made from synthetic materials, such as polyester and nylon, has many positive attributes. It is cheap to produce, lasts for a long time, and is comfortable to wear. However, the fabric, made from petroleum, has one major downside. The tiny polymer strands — or what we call lint — that shed from the textiles during each laundry cycle are big contributors to plastic pollution. Now, some scientists from Lithuania have found a way to recycle the textile waste into clean energy....

But that is exactly what was done to one of Rembrandt van Rijn's most famous works, The Night Watch, almost 300 years ago. Now, Amsterdam's Rijksmuseum has finally managed to restore the painting to its original glory with the help of artificial intelligence (AI)....

For most people, Friday the 13th is just another day on the calendar. However, for the superstitious, it is the unluckiest day of the year. The irrational fear of Friday the 13th is called friggatriskaidekaphobia. It affects over twenty million people in the US and many more worldwide. Some of the anxiety can be blamed on the namesake movie series. However, the day's bad reputation began long before the film's hockey-masked villain, Jason Voorhees, made his debut in 1980....

However, a psychological condition, known as "the twisties," can sidetrack even the most experienced gymnast. The phenomenon, attributed to stress, disorients the athletes and causes them to lose awareness while they are in the middle of a routine. It can lead to serious injury....

Though the meteors will peak the night of August 11, 2021, they will be visible on the days before and after as well....
