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 […]
ARE WE IN A SIMULATION?
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 […]
HOW QUANTUM COMPUTERS WORK?
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 […]
HOW TRANSISTORS WORK? (BEGINNERS EDITION)
Transistors are indeed one of the revolutionary inventions that man has ever made. The function of the transistor is to switch and amplify electrical currents. The number of transistors in dense integrated circuit doubles about every two years. This is Moore’s law. In today’s post, I will introduce you to the semiconductor world and will explain the working of a transistor which has revolutionized our […]
JOURNEY THROUGH QUANTUM MECHANICS
It’s true that there are only a few people who truly understand Quantum phenomena and are able to give satisfactory explanations to others. Quantum Mechanics has always been one of the mindboggling domains in physics. This micro-world never misses an opportunity to surprise us and is always unpredictable. Thanks to the most powerful tool of mathematics because of which we can explore the deepest mysteries of science. In 1808, […]
WHY MATTER?
After the Big Bang, it’s predicted that our universe had equal and large quantities of matter and anti-matter, but today we observe only matter around us, no anti-matter. So why this imbalance of matter and anti-matter occurred at the beginning of our universe? What exactly caused matter to dominate over anti-matter? Well, such a question might be answered by baryonic asymmetry or CP-violation. The CP-symmetry […]
HIGGS MECHANISM AND ITS MISCONCEPTIONS
In my last blog post, ‘working of the large hadron collider‘, I talked about the Higgs boson (famously known as the ‘God particle’) at a certain instant. Today I will be explaining the Higgs mechanism and will unveil some common misconceptions with Higgs boson. I would also introduce some quantum mechanical equations for better understanding. So throw all your interpretations about the Higgs mechanism and start with […]
