![]() He hoped to promote it as a general germicide and collaborated with pharmacist Jordan Wheat Lambert who started the Lambert Pharmaceutical Company to manufacture it.Īt first, Listerine was sold a cure for gonorrhea and a floor cleaner. Louis, developed a formula which he named “Listerine” in honor of Lister.

The same thing happens when a pressure-sensitive tape such as Scotch tape is pulled away from the roll in a vacuum. Diamonds also fluoresce blue or red sometimes when rubbed, ground, or sawed, and minerals like quartz emit light when rubbed together. This optical phenomenon is known as “triboluminescence.” It can be observed when you bite on a Wint-O-Green LifeSavers candy in the dark as the wintergreen oil, which is fluorescent, converts ultraviolet light into blue light. When ripped, scratched, or crushed, some materials generate light as the chemical bonds break and the electrical charges are separated and reunified. The Eldredge knot or Trinity knot, which the mathematician himself uses every day, requires the same number of winding moves. ![]() Instead of eight winding moves, Vejdemo-Johansson chose 11 moves. He became interested in this tie-knotting business after watching a YouTube tutorial on replicating the intricate, exotic-looking knot worn by the Merovingian as shown in The Matrix Reloaded film. Later, another mathematician, Mikael Vejdemo-Johansson from the KTH Royal Institute of Technology, Stockholm, Sweden, put the number at 177,147. They also put a limit on the number of winding moves at eight. However, they made the calculations under two main assumptions – that you would only tuck at the end of all the folding, and that all knots would be covered by a flat stretch of the tie fabric. In 1999, two mathematicians, Thomas Fink and Yong Mao from the University of Cambridge, calculated the number of knots that can be used for men’s neckties was 85.
