A very large number and some well-known numbers

This question naturally arises in the mind of all of us which is the biggest number. In the field of knowledge, this question is the first step towards moving from the known to the unknown and from the concrete to the abstract. Common sense says that no single number can be the largest number because numbers go on increasing and point toward infinity. If you want, you can think of the largest number, for this, you have to arrange the digits from 0 to 9 in any logical or desired order! But it is a futile activity in itself as such numbers have no significance. Nevertheless, some supergiant numbers have been hypothesized in mathematics and science. Such gigantic numbers are found in the form of solutions to some mathematical calculus and theorems and their importance has been accepted as a mathematical solution to a problem.

Graham's number and Poincare recurrence time have been discussed in previous posts on large numbers. In this post, along with the introduction of another huge number, some other interesting numbers are being told: -

1.  2 4,31,12,609 – 1

There are approximately one crore thirty lakh digits in this number. What is special about this number? It is the largest prime number or prime number known so far. A prime number is one that can only be divided by 1 or the same number. This number was detected in the year 2008 by the Great Internet Messene Prime Search (GIMPS), a software designed to search for the largest prime number. Note, this is only the largest known prime number, there may be larger prime numbers but they have not yet been discovered.

2.  -273.15°C

This centigrade temperature is also called absolute zero or zero-degree Kelvin temperature. On a theoretical basis, it can be said that energy is neither emitted nor absorbed at this temperature. At this point of temperature, the energy of any particle becomes almost zero, which can be determined on the basis of the laws of quantum dynamics. It is believed that absolute zero temperature is not possible at any place in the universe because some energy is present even in such places where there is nothing thousands and millions of light years away. This level of temperature cannot be reached, but scientists have been able to reach temperatures close to it, and they have observed that materials at temperatures near absolute zero exhibit strange quantum properties such as superconductivity and superfluidity. and superfluidity).

3.  -40

This is a unique number in the field of temperature measurement because at this temperature the centigrade and Fahrenheit scales meet, ie -40°F is the same temperature as -40°C.

4.  3888

This number is the largest number that can be written in the Roman numeral system. It is written in Roman as MMMDCCCLXXVIII.

5.  Pi (π)

In Euclid's geometry, pi or π is the ratio of the circumference of a circle to its diameter. Its value is approximately 3.14159. It is the most important mathematical constant used in mathematics, physics, and engineering. It is also called Archimedes' constant.

6.  1.6180234878

This is called the golden ratio. In mathematics and art, two quantities are considered to be in the golden ratio if the ratio between the sum of those quantities and the larger quantity is the same as that between the larger quantity and the smaller quantity. The golden ratio is approximately 1.6180339887. Artists and architects have been using this ratio in their artworks and architecture since the Renaissance era and they believe that the artworks created on its basis are beautiful. I do not understand this thing.
