C R Rao gone

“All knowledge is, in final analysis, history.

All sciences are, in the abstract, mathematics.

All judgements are, in their rationale, statistics.”

— C. R. Rao (1920–2023) Very sad to learn that C R Rao who pioneered. information geometry passed away August 22nd at the age of 102 years.

Hyderabad: Indian American Mathematician Calyampudi Radhakrishna Rao, commonly known as C. R. Rao passed away on Wednesday. He is 102.

C. R. Rao was born to a Telugu family in Hadagali, Bellary, Madras Presidency (now in Karnataka), India. His schooling was completed in Gudur, Nuzvid, Nandigama, and Visakhapatnam, all in the present state of Andhra Pradesh. He received an MSc in mathematics from Andhra University and an MA in statistics from Calcutta University in 1943. He obtained a Ph.D. degree at King’s College in Cambridge University under R. A. Fisher in 1948, to which he added a DSc degree, also from Cambridge, in 1965.

The Indian American statistician was recently awarded International Prize in Statistics, which is statistics’ equivalent of the Nobel Prize. The most distinguished exponent of the subject, Calyampudi Radhakrishna Rao’s monumental work across several branches of statistics and its applications, is noteworthy.

抽象地说，所有科学都是数学。

所有的判断，就其基本原理而言，都是统计数据。”
