Introduction RSA (Rivest–Shamir–Adleman) encryption has been long in use now and has a nimiety of applications, even as far as being used by government agencies. Now, RSA encryption makes use of the fact that some problems are elementary to solve one way but not so trivial to solve the other way. For example, if I ask you, what is the prime factor of 701,111 it […]

As the SARS-CoV-2 cases continue to surge globally, scientists, engineers, and young entrepreneurs are coming with simple yet innovative solutions to fight against the pandemic. Like C-Safekey, Social distancing Device, Affordable N95 masks, etc. Today, I would like to share how as simple as airflow could prevent you from getting COVID-19! What’s the Physics behind airflow? In Physics, the air is analogous to a fluid. […]

Albert Einstein, in his 1905 paper (On the electrodynamics of moving bodies) formulated a physical theory that described the relationship between space and time. This theory which was built on the earlier work of Hendrik Lorentz is the special theory of relativity. The incompatibility of Newtonian mechanics with Maxwell equations of electromagnetism and Michelson-Morley experiment which demonstrated the non-existence of aether led Einstein to develop […]

Back in the early 1970s, Stephen Hawking wrote an astonishing equation which included quantum mechanics, relativity and information. Hawking’s rather simple equation bought us closer to understanding the relationship between quantum physics and black holes. When an object gets closer to a black hole, the tidal forces crush the object. The information (arrangement of particles in some sense) of these objects shatters away completely. But the […]

Quantum Mechanics has been an all-time favorite topic for all science nerd, however, it’s truly a tedious job to understand the quantum phenomena and even more tedious when it comes to experimenting these effects (To know the three eras of quantum mechanics, check out my post ‘Journey through the quantum mechanics‘). One such experiment is making an economically viable and efficient Quantum Computer (to understand […]

In the classical computation model, the computer has access to memory which can be found in one of a finite set of possible states, each of which is physically distinct. The state of this memory is generally represented as a string of symbols 0 and 1. In the classical computation model, the fundamental unit of memory is called bit and the size of the memory […]

Development in science and technology has truly revolutionized our standard of living. Computers, smartphones, and smartwatches have become a part of our lives and we can’t afford to stay without them in this fast-moving world. But the batteries, which give the potential for our devices to work, drain quickly and its recharging is truly time-consuming, also the batteries are nonbiodegradable and a waste of natural resources.
