In 1666, Newton determined π to 16 places using 22 terms of this series. He then wrote: "I am ashamed to tell you to how many figures I carried these computations, having no other business at the time"

The Role of Vectors in Machine Learning We hear over and over that machine learning is linear algebra, which, in turn, has to do with vectors and matrices. But why? What’s so amazing about this particular mathematical discipline as it pertains to ML? Here, from a bird’s eye-view,

NEW: Harvard University on Monday announced that tuition will be free for students from families with annual incomes of $200,000 or less starting in the 2025-26 academic year. abcnews.link/j661fIP

🔭💥 200 gravitational wave candidates in O4! From 90 in O1-O3 to 200+ now is proof of incredible detector upgrades. Each new signal sharpens the physics we understand of black holes, neutron stars & spacetime. What's next? Such exciting times! #GravitationalWaves #LIGO #Virgo

DESI has made the largest 3D map of our Universe to date Earth is at the center in this animation, each blue point is a galaxy: > 14 million galaxies in total up to 11 billion light years away The gaps are the regions where our own galaxy blocks the view

Congratulations!!!

A. Einstein about his 'intuition' of general relativity (1929) ✍️ I believe in intuitions and inspirations. I sometimes feel that I am right. I do not know that I am. When two expeditions of scientists, financed by the Royal Academy, went forth to test my theory of relativity, I

Fermat's Last Theorem is not applicable to matrices

37 is the 12th prime and 73 is the 21st prime.

The Indian astronomy community mourns the passing of Prof. J.V. Narlikar, a luminary in astrophysics & cosmology, institution builder, science communicator par excellence. His founding of IUCAA & efforts to promote astronomy in universities transformed Indian science. Inter-University Centre for Astronomy&Astrophysics

An outstanding astrophysicist, giant of Indian science and superb science communicator and educator who founded India’s premier astronomy and astrophysics institute. RIP. indianexpress.com/article/cities…

A playlist of some wonderful talks and interactions by or including Prof. Jayant V Narlikar recorded by IUCAA Scipop at Inter-University Centre for Astronomy&Astrophysics over the years. His commitment to fostering scientific temper across society was phenomenal. youtube.com/watch?v=gycppn…

The passing of Dr. Jayant Narlikar is a monumental loss to the scientific community. He was a luminary, especially in the field of astrophysics. His pioneering works, especially key theoretical frameworks will be valued by generations of researchers. He made a mark as an

Jayant Narlikar, visionary Indian astrophysicist, who challenged the Big Bang, co-developed an alternative cosmology, passes away at 86. Read about the passionate science communicator’s life and science in #NatureIndia’s #Obit by Pranav Sharma nature.com/articles/d4415…

Dr Jayant Vishnu Narlikar is no more. A celestial flame has dimmed on Earth, only to shine brighter among the stars he once deciphered. I begin my tribute to recalling the blessings that I received from Mrs Taratai Bole, when I returned to India 50 years ago. She said, “You

This is wonderful: Roy Kerr who discovered an exact solution to Einstein's field equations for spinning black holes - a solution that Subrahmanyan Chandrasekhar called "shuddering before the beautiful" - attributes his success (where others had failed) to his maverick approach.

The paper is out here: pole.uchicago.edu/public/data/ca… Of personal interest: the full range of neutrino masses allowed by neutrino oscillations are now excluded at 98% confidence.

POV: You think you're attending a quantum gravity conference, but it's just a Lenny Susskind birthday party in disguise.

I had a wonderful week with Subir Sarkar, with a bit of adventure. Learned a lot of cosmology and life. Subir is full of wisdom, not just great physics.

Today is July 29. #OTD in 1898 physicist Isidor Rabi was born. He received the The Nobel Prize in Physics in 1944 "for his resonance method for recording the magnetic properties of atomic nuclei". Also one of the 1st to work on the cavity magnetron, used in radar and microwave ovens.
