Magical number :73

Seventy three is a magical number and has so many strange properties that are rare to be found in many of the other numbers.

The digits of 73, '7' and '3' when multiplied yield 21, and 73 is the 21st prime number!!!

Also the reverse of 73 yields 37 which is the 12th prime number which is also a reverse of 21!!!

Finding out the binary form of 73 yields 1001001 which is a palindrome!!!

And that's not all 37 + 12 = 49 (seven squared) and 73 + 21 = 94 = 47*2, 47+2 also being equal to 49.

This similar phenomenon or the magical property of 73 was also mentioned in "The Big Bang Theory".
That's all for this edition of magical numbers, stay posted for more such numbers.

Much similar to the infamous Bermuda's triangle, dragon's triangle has seen many disappearings. The Dragon’s Triangle follows a line from Western Japan, north of Tokyo, to a point in the Pacific at approximate latitude of 145 degrees east. It turns west south west, past the Bonin Islands, then down to Guam and Yap, west towards Taiwan, before heading back to Japan in a north north easterly direction. The existence of agonic lines - lines of no magnetic variation, along which the magnetic needle points directly north and south. The principle agonic line in the Western Hemisphere runs directly through the Bermuda triangle, whilst the principle agonic line in the Eastern Hemisphere runs through the Dragon’s triangle. Which in both cases often leads to extreme compass deviation in the surrounding area. For over

Cruel History

This post like most with similar topics, would seem like ranting about things in the past. I've been doing some research into world history and various major events that shaped the world we live in today. The past is filled with atrocities, which makes us humans seem like the lowest form of animal species to ever walk on this beautiful earth. So, let's start with dictatorship. I never realized this, but when it comes to the most cruel dictators of all time, Hitler isn't really on the top spot. The man who even dwarfs Hitler's crime against humanity is Joseph Stalin. The man was a nightmare to deal with, responsible for over about 49 million deaths. Then, there is Mao Zedong perhaps the most cruel dictator of all time, responsible for 45 million deaths in just 4 years. With respect to all of this, the Indian independence struggle and the great war of 1857 seem like just a bad day (perhaps an over exaggeration on my part). As, I was exploring this I came across Nanki
