“What are Significant Figures?”, “What are they used for?”, “What is their significance?” Students often ask these questions because why would you want to identify significant numbers, if you can do mathematical calculations without them, right? Where the idea of using significant figures might come off as unnecessary, it is a crucial concept that you…

A transistor is a semiconductor gadget used for amplifying or switching electronic signals and electrical power. It is built with a single piece of semiconductor material and consists of three terminals connected to the external circuit. If you provide any voltage through one end of a transistor, it changes the current flow through the rest…

Looking for recommendations on the best statistical mechanics textbooks? In this article, I have listed some of the best statistical mechanics books for Statistical Physics majors. In this list, I have collected only those books that are loved by both teachers and students. These books are considered the top textbooks in all the colleges and…

Are you looking for the best General Relativity books to start your studies in the Theory of Relativity? Relativity, Spacetime, Gravitational Theory, Quantum Mechanics and String Theory, etc., are some of the most important branches of advanced physics. If you are looking to have a career in these, these General Relativity books for beginners may…

I don’t feel that I should explain the importance of kinematics in Physics. Kinematic equations form the very foundation of any question you intend to solve in physics. Be it uniform rectilinear motion or rotational motion, these equations will always help you to find the correct answer. Whether you are preparing for NEET or JEE…

In this article we will learn everything about the life of Chandrasekhar Venkat (CV) Raman, Raman Spectroscopy, Raman Effect and Raman Scattering in detail. Useful for graduate and undergraduate students. About CV Raman Sir Chandrasekhar Venkat Raman, also known as Sir CV Raman, was a Physicist, Mathematician and a Nobel Laureate. Venkat (his first name)…

In a collaborative attempt, astrophysicists from different institutions have found success in discovery of A1689B11 – a spiral galaxy that’s said to be the oldest discovered. The research reports an integral-field spectroscopic (IFS) observation of this gravitationally lensed spiral galaxy. It is the most ancient one till date and is calculated to be 11 billion years…

‘Symmetry’ has a special meaning in physics. A picture is said to be symmetrical if one side is somehow the same as the other side. Precisely, a thing is symmetrical if one can subject it to a certain operation and it appears exactly the same after the operation. For example, if we look at a…

In this article we will define what are Macrostates and Microstates in Statistical Physics with examples and illustrations. Consider some (4, say) distinguishable particles. If we wish to distribute them into two exactly similar compartments in an open box, then the priori probability for a particle of going into any one of the compartments will…

What if we make a tunnel through the earth and drop a ball or any other body into it? How would the gravity behave on the ball, and , will the ball pop-up on the other side? If yes, then how much time will it take? A question, which is usually asked in competitive exams…

Ensembles As a system is defined by the collection of a large number of particles, so the “ensembles” can be defined as a collection of a number macroscopically identical but essentially independent systems. Here the term macroscopically identical means, as, each of the systems constituting an ensemble satisfies the same macroscopic conditions, like Volume, Energy,…

This is a small story of Nanotechnology, one of the most advanced and trending topics in physics. Nanotechnology has become a widely discussed topic today in newspapers, magazines, journals, blogs and even in television ads. It’s very common that some organization announcing ‘yet another’ “nano-conference”. Nanotechnology or nanotech in short, refers to the technology of creating…
