The only reason why I am writing review of a 21 minute episode is because it's very special to me. Sheldon proposes a topic to discuss socially amongst friends. He continues in spite of negligence of friends in comedic manner and ends his conversation. The topic of discussion is number 73. How it is prime number at 21st position and its opposite i.e. the number with replaced digits is a prime at 12th position i.e. 37. He further explains it's a palindrome as well. I would like to add here is 73 is an emirp, meaning that the reverse of 73, that is, 37, is also a prime number. 73 is a star number. 73 in base 36 number conversion is 21. The number 21 has prime factors 7 and 3. The number 21 in binary is 10101; 7 in binary is 111, 3 in binary is 11, and seventy-three in binary is 1001001.
Thus my friends I would really like u to watch this episode and enjoy!
