@jacktcc1: My friend Adam. He gave his buddies in school 28 sweets to them what a nice guy 😊 | Graham’s number is one of the largest numbers ever to appear in a serious mathematical proof. It was introduced by mathematician Ronald Graham while working on a problem in a branch of mathematics called combinatorics. Although it is incredibly large, it is still a finite number. This means that Graham’s number is not infinity. It has a specific value, even though that value is so unimaginably huge that it cannot be written down in ordinary decimal notation. To understand how large Graham’s number is, it helps to start with smaller numbers and work upward. The number 10 is a small number. The number 100 is larger. The number 1,000 is larger still. A million is 1,000,000. A billion is 1,000,000,000. A trillion is 1,000,000,000,000. These numbers are enormous from a human perspective, but they are tiny compared to numbers used in higher mathematics. Consider a googol. A googol is: 10^100 That means a 1 followed by one hundred zeros. A googol is much larger than the estimated number of atoms in many familiar objects. Now consider a googolplex: 10^(10^100) A googolplex is so large that writing all its digits would require more space than exists in the observable universe. Yet a googolplex is still unbelievably tiny compared to Graham’s number. Mathematicians use special notation to describe numbers that become too large for ordinary exponentiation. One such notation is Knuth’s up-arrow notation. Examples: 3 ↑ 3 = 27 3 ↑↑ 3 = 3^(3^3) 3 ↑↑ 4 = 3^(3^(3^3)) Already this number is gigantic. Then there is: 3 ↑↑↑ 3 Which means repeated tetration. Then: 3 ↑↑↑↑ 3 Which is even larger. Then: 3 ↑↑↑↑↑ 3 And the numbers continue growing at rates that completely overwhelm normal intuition. Graham’s number is not simply one huge exponent. It is not a tower of exponents. It is not a tower of towers of exponents. It is not a tower of towers of towers of exponents. Instead, Graham’s number is constructed through a sequence of numbers where each stage becomes the input for the next stage. The first stage is already so large that describing it precisely requires advanced notation. The second stage uses the first stage as the number of arrows. The third stage uses the second stage as the number of arrows. This process repeats again and again. Sixty-four total stages are used. The final result after the sixty-fourth stage is Graham’s number. Trying to visualize Graham’s number is impossible. Suppose every atom in the observable universe were converted into paper. Suppose every piece of paper contained digits. Suppose every digit was microscopic. Suppose every universe-sized collection of paper was duplicated trillions upon trillions of times. You still would not come remotely close to writing down Graham’s number. Even the number of digits in Graham’s number is unimaginably huge. Even the number of digits in the number of digits in Graham’s number is unimaginably huge. Even repeating this idea many times does not adequately capture its size. One reason Graham’s number became famous is that it was once recognized as one of the largest numbers ever used in a mathematical proof. The problem involved high-dimensional geometry and combinatorics. Interestingly, later research showed that much smaller numbers could be used as upper bounds for the same problem. However, Graham’s number remained famous because of its extraordinary size. People sometimes assume Graham’s number is the largest number known to mathematics. This is not true. Many larger numbers have been defined. Examples include numbers created using advanced fast-growing hierarchies. Some mathematical functions eventually produce values that dwarf Graham’s number. For example, certain values related to TREE(3) are vastly larger than Graham’s number. Likewise, some values in the fast-growing hierarchy exceed Graham’s number by incomprehensible amounts. #tcc #truecringecomunnity #edit #sinister #fyp
