Enigma of chess

-


Many of you must have played chess atleast once in life. Have you ever thought that there are more possible iteration of a Game of chess than Atoms in observable universe. Intersting Right! 

Let's look more into it~ 

 The number of possible ways of playing the first four moves per side in chess is greater than the number of atoms in the observable universe. 

HOW!?

In chess, each player has 20 possible opening moves for their pawns and 16 possible opening moves for their pieces  leading to an expansive number of potential positions right from the start. As the game progresses, the number of possible moves for each player increases exponentially with each turn. The total number of possible chess games is estimated to be on the order of 10^120, a staggeringly large number often referred to as the Shannon number, named after Claude Shannon, a mathematician and computer scientist. This astronomical figure far surpasses the estimated number of atoms in the observable universe, which is on the order of 10^80 to 10^82


This comparison to the number of atoms in the observable universe serves to emphasize the extraordinary depth and intricacy embedded within the rules and possibilities of the game of chess.

I was mindblown when I came to know this, I'm pretty sure you also felt the same when you read this ! 


Next time whenever you play chess remeber this fact and make your and your opponents game more interesting 😉

Is It Possible To Sneeze With Your Eyes Open?

You've probably heard the rumor that you can't sneeze with your eyes open because your eyes will pop out if you do. Is it impossible to sneeze with your eyes open? Let's find out in today's blog.   You've probably noticed that whenever you sneeze, your eyes automatically close right before you sneeze; most of us learn this eye-popping rumor, and honestly, and luckily it's a myth, your eyes will definitely not pop out. Fear not, fellow sneezers! The act of sneezing — also known as sternutation — will not cause your eyes to pop out, even if you do sneeze with your eyes open. If you sneeze, your eyes close just before a sneeze as an involuntary reflex; the brain sends a signal to the eye muscles telling them to close without you ever having to think about it. But why do our eyes automatically close? Experts can't say for sure, but many believe it could be a reflex that keeps all the icky stuff we sneeze out. Sneezing is just a way for your body to get rid of

INTRESTING FACTS ABOUT WATER!!!

        There aren’t many qualities that are true of all life on Earth, but the need for water is one of them. It is in all living things, whether they live in the sea or the desert. Water made life possible on Earth. Here are some interesting facts about water that you may or may not know : ● Hot water freezes faster than cold water. The Mpemba effect is the name given to this observation. It states that there exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will freeze sooner. The hot water cools faster because of the bigger difference in temperature between the water and the freezer, and this helps it reach its freezing point before the cold water reaches its natural freezing point, which is at least 5°C lower. Also, all the conditions must be controlled, such as the location of the samples in the freezer, and the type of contain

The mystery of Bigfoot

Bigfoot, or Sasquatch, is a giant ape-like creature that some people believe roams North America. It is a cryptid (opens in new tab) (or species rumored to exist), and just like the Chupacabra or Loch Ness monster(opens in new tab), there's scant physical evidence to suggest bigfoot is actually out there. But that doesn't stop alleged sightings of the ape that never shows its face or Bigfoot buffs from trying to prove there's life in the legend. Most Bigfoot sightings occur in the Northwest, where the creature can be linked to Indigenous myths and legends. The word Sasquatch is derived from Sasq'ets, a word from the Halq'emeylem language used by some Salish First Nations peoples in southwestern British Columbia, according to the Oregon Encyclopedia(opens in new tab). It means "wild man" or "hairy man" .   HISTORY OF BIGFOOT In 1958, Jerry Crew, a logging company bulldozer operator in Humboldt County, California, discovered a set of large, 410 mi
