## The Nobel Prize in Chemistry 2013

Classical mechanics is considered to be just opposite to quantum physics in terms of theory and practical models. Classical mechanics, especially Newtonian Mechanics, and quantum mechanics are definitely two fundamental but equally different branches of physics having no significant connection to each other. These completely disjoint subjects were glued by the work of the trio of Martin Karplus, Michale…

## Finally a Physics Nobel Prize for Higgs boson Theorists

The 2013 Nobel Prize for physics has been awarded to Peter Higgs and Francois Englert for their remarkable contributions to the theory of Higgs boson “God Particles”. It came after 50 years Peter Higgs, Robert Brout, Gerald Guralnik, C R Hagen, T. W. B. Kibble and Francois Englert independently announced the existence of Higgs boson in 1964 to put the…

## Some good, OK, and useless revision techniques

Exam have been haunting student since forever, and although you’re willing to do whatever you can to retain essential information, sometimes you end up spending weeks studying with useless revision techniques. We’re accustomed to employ our own techniques when it comes to studying such as making sticky notes, highlighting, or drawing charts. However, recent studies conducted in the US have…

## Complete Elementary Analysis of Nested radicals

This is a continuation of the series of summer projects sponsored by department of science and technology, government of India. In this project work, I have worked to collect and expand what Ramanujan did with Nested Radicals and summarized all important facts into the one article. In the article, there are formulas, formulas and only formulas — I think this…

## Light the bulb: An everyday logic puzzle

You are inside a room and there are exactly three electric bulbs outside of the room. The three bulbs have their corresponding switches (exactly three) inside the room. You can turn the switches on and off and leave them in any position. How would you identify which switch corresponds to which electric bulb, if you are allowed to go outside…

## When nothing is everything in Set theory

In an earlier post, I discussed the basic and most important aspects of Set theory, Functions and Real Number System. In the same, there was a significant discussion about the union and intersection of sets. Restating the facts again, given a collection $\mathcal{A}$ of sets, the union of the elements of $\mathcal{A}$ is defined by \$ \displaystyle{\bigcup_{A \in…

## Why You Need To Take A Level Courses?

Have you ever wondered why you need to take A level courses? This question has been asked plenty of times. A level courses offer several benefits to students over those that only have O-level education. Understanding these benefits is the only way to persuade more people to further their education when they may be so reluctant to do so.…

## Hopalong Orbits Visualizer: Stunning WebGL Experiment

Just discovered Barry Martin’s Hopalong Orbits Visualizer — an excellent abstract visualization, which is rendered in 3D using Hopalong Attractor algorithm, WebGL and Mrdoob’s three.js project. Hop to the source website using your desktop browser (with WebGl and Javascript support) and enjoy the magic. PS: Hopalong Attractor Algorithm Hopalong Attractor predicts the locus of points in 2D using this algorithm…

## Photo Archives from ‘Only Gaurav’

‘Only Gaurav‘ was a photo-blog, I operated parallel to MY DIGITAL NOTEBOOK. Both sites worked well together until February 2012. After February 2012, I got busy in college stuffs and my blogging life took a huge leap of one year. MY DIGITAL NOTEBOOK was able to survive this gap and now it is continuously getting updated. On the other hand,…
