The Big Bang Theory is the most widely accepted theory regarding the formation of the universe. It was discovered that the universe is moving away from us in all directions, that is, expanding at a tremendous rate. This concept has been verified with the redshift of galaxies and the cosmic microwave background. At the very …
Lavanya Arora The quantum world hosts a lot of staggering and interesting phenomena. One of these is quantum tunneling. It is a process in which a particle with less energy penetrates through a barrier with higher energy. The most common example scientists give to explain this is that of a ball and a hill. Consider …
1. Aim and Motivation a. Motivation What is light? Many scientists from the past have questioned this. What I learned about light through science classes and literature research is that light has two different characteristics. In summary, light exhibits wave-particle duality. Scientific observation of the nature of light is a complicated problem. Einstein\’s photoelectric experiment …

Abstract Viscosity is basically the measure of resistance of a fluid when it is flowing, i.e. it describes the internal friction of a moving fluid. In 1851 scientist George Gabriel Stokes gave his law; after that, a lot of research was done with taking that law into account. But there are no such mathematical solutions …

This project looks at the application of general-purpose CFD to two plasma propulsion engines. Verification against experimental data for a 200 kW engine was undertaken, achieving similar thrust levels and jet exhaust divergence angles. A scaled-up 30 MW engine, capable of interplanetary travel, showed similar operating behaviour to the test engine. The increased seventy-fold thrust …
Abstract: This study was conducted in an effort to confirm or deny the existence of the Mpemba effect. The Mpemba effect states that when identical bodies of water at two different temperatures are exposed to a physical cooling agent, the body with a higher starting temperature will cool faster than its counterpart. The experiment was …

On improving take-off efficiency of airplanes Arpan Dey Abstract In this paper, a special model for the airplane wing is proposed. The main aim of the model is to maximize take-off efficiency of airplanes and increase the effectiveness of in-flight maneuvers. The sudden movement of a leading-edge downward-movable control surface in the main wing could, …

Has anybody ever wondered why almost every object we see in the universe is spherical? From the smallest atoms to the immensely massive stars, all are spheres. Even the galaxies which are now flat and oval-shaped are believed to have commenced as spherical balls of hot gas and other materials. “Why is the universe biased …
Image credit: Getty Images Aaditya Bhattacharya[1]* Abstract The article explores and explains the evolving concept of “gravitational waves”. It presents the importance of and recent progress in the contemporary knowledge of “gravitational waves”. It provides a brief overview of the interferometer – an instrument used to measure these gravitational waves. The article elucidates …
