The Number

Narendra Modi, Prime Minister of India, paid tribute to Srinivasa Ramanujan: “A genius who made a monumental contribution to mathematics, I pay my tributes to the legendary S Ramanujan on his birth anniversary.”

It is Srinivasa Ramanujan’s 127th birth anniversary.

As a Mersenne prime, 127 is related to the perfect number 8128. 127 is also an exponent for another Mersenne prime 2127 – 1 (2127 – 1), which was discovered by Édouard Lucas in 1876, and held the record for the largest known prime for 75 years – it is still the largest prime ever discovered by hand calculations. Furthermore, 127 is equal to 27 – 1, and because 7 is also a Mersenne prime, this makes 127 a double Mersenne prime.

127 is also a cuban prime of the form p = (x^3 – y^3) / (x – y), x = y + 1. The next prime is 131, with which it comprises a cousin prime. Because the next odd number, 129, is a semiprime, 127 is a Chen prime. 127 is greater than the arithmetic mean of its two neighboring primes, thus it is a strong prime.
127 cannot be written as a sum of a power of 2 and a prime, the next is 149.
127 is a centered hexagonal number.
It is the 7th Motzkin number.
127 is a palindromic prime in nonary and binary.
It is the first nice Friedman number in base 10, since 127 = -1 + 27, as well as binary since 1111111 = (1 + 1)111 – 1 * 1.

Ramanujan would have known THIS NUMBER too.

The Premise

The Premise of Temperament

Professor Keirsey's Blog

“The history of philosophy is to a great extent that of a certain clash of human temperaments. Undignified as such a treatment may seem to some of my colleagues, I shall have to take account of this clash and explain a good many of the divergences of philosophers by it. Of whatever temperament a professional philosopher is, he tries, when philosophizing, to sink the fact of his temperament. Temperament is no conventionally recognized reason, so he urges impersonal reasons only for his conclusions. Yet his temperament really gives him a stronger bias than any of his more strictly objective premises. It loads the evidence for him one way or the other, making for a more sentimental or hard-hearted view of the universe, just as this fact or that principle would. He trusts his temperament. Wanting a universe that suits it, he believes in any representation of the universe that…

The Revolution of Corrective Counseling

It is a slow idea, someday it will catch on. Meanwhile, good luck for those in the grip of psychiatry and the DSM V, … DSM IV…

This revolution revealed to those who cared to look that every successful method of corrective counseling owed its success, not to the factor guessed at by its inventor, but to the unintentional “prescription of the symptom.” Logical investigation of successful methods invariably led to the same conclusion: each useful method in its own way entails “symptom prescription” as practiced by Milton Erickson. It was clear to those who studied Erickson’s method of encouraging clients to practice their symptoms under his supervision that Rogers’sreflection, Kelly’srole assignment, Stampfl’simplosion, Wolpe’sreciprocal inhibition,Ellis’sinsane sentencing, Moreno’srole directing,Adler’slogical consequences, Berne’spermission, Glasser’sbite-sized assignments, Skinner’srewards, Eglash’srestitution, and…

It Stands to Reason

Happy Birthday Sharon. She has been a libertarian activist for 50 years, and she hopes that she will have a few more years to fight for liberty. She is not slowing down if she can help it. She is finishing the libertarian feminist anthology, hoping to start a libertarian women’s magazine with Victoria Varga sometime this year, work on her book about American women resisters in the 19th century and other ideas in the offing. No rocking chair for her! Self and Herd-appointed Experts watch out.
