As a number theory researcher, I recommend George E. Andrews’s Number Theory. It explains ideas like divisibility, congruences, and simple equations in a very clear way. At around 200 pages, it’s short and to the point, with plenty of examples and exercises you can check by hand

On the 136th day of the year, we come across these beautifully constructed summation formulas that distinctively depict the number 136, making use of both Fibonacci, Lucas sequences.

I tried to explain the Śrī Chakra through the lens of topology. It’s not just a sacred symbol — it’s a beautifully complex graph with deep mathematical structure. One connected piece, 43 interwoven loops, and a rich network of paths. Viewing the Śrī Chakra as a 1-dimensional

In this poster I explained the math and tech behind QR codes; from how bits are packed (numeric, alphanumeric, byte modes) to the Reed–Solomon error correction over GF(2⁸), BCH‐protected format bits, module placement and masking strategies, and even the decoding pipeline.

On the 138th day of the year, we explore beautifully constructed summation expressions that distinctly represent the number 138, using Fibonacci numbers, Lucas numbers, and the Binomial coefficient.

#Math is fun!

Here is an interesting page from the book Why Machines Learn: by Anil Ananthaswamy , sir. I think neural nets aren’t magic. Take the tiny XOR model: two hidden units feed one output unit that squashes their signals. Training just means seeing how each of its eight little knobs (weights

Linearize Einstein’s vacuum equations around flat spacetime, drop the higher-order terms, and you land on □ h = 0—the classic wave equation. Its null, transverse ripples travelling at light-speed are exactly the #GravitationalWaves LIGO hears.

On the 140th day of the year, we have this remarkable representation of the number 140 using the exponential function, π, and the Golden Ratio.

Famous Indian Scientist Prof J V Narlikar passed away this morning. It is a big disturbing shock to me. Om Shanti!

Today, we lost the legendary Indian astrophysicist & cosmologist Prof. Jayant Vishnu Narlikar—a profound loss to the scientific community. Pioneer of astrophysics, promoter of scientific thinking, and inspiration to countless young minds. Meeting him at IUCAA in 2014 was

On the 141st day of the year, here is a beautiful identity involving the sum of powers of the Golden Ratio that elegantly represents the number 141.

I enjoy quantum computing because its “qubits” can hold many values at once and even link together in ways regular bits can’t. In the table I shared, I show the main differences between today’s computers and quantum machines: how they store data, do work, fix mistakes, and the

For today's date: 23/5/2025 2352 + 025 is a Prime number 23 + 5 + 2025 is a Prime number 23 + 5 - 20 - 25 is a Prime number 23 + 5 + 20 - 25 is a Prime number 23 + 5 + 20 + 25 is a Prime number 23 + 5 + 20 - 2 - 5 is a Prime number 23 + 5 + 2 + 0 + 2 + 5 is a Prime number 2 + 3

As we arrive at the 144th day of the year, here are some elegant expressions of the number 144 using Fibonacci, Lucas, and triangular numbers.

As a mathematics teacher, I recommend “The Essence of Mathematics Through Elementary Problems” to anyone curious about how math ideas grow from simple puzzles. The book presents each topic as a question first, then shows the main idea behind it, making learning feel like solving

For the 145th day of the year, we have this magical representation of the number 145 using factorials.

Thank you, sir, for this fascinating and well-researched post on the origins of the wheel! The evidence you’ve presented for the independent development of wheeled technology in the IVC, like the terracotta carts from Harappa (3500 BC) and the Sanauli/Tilwara ox-carts, is
