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 […]
PROOF OF STOKES LAW OF VISCOSITY USING REYNOLDS LAW THE UNIVERSITY OF BURDWAN Author’s name: Arup Shit Qualification: Undergraduate (Physics) Gmail ID: [email protected] 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 […]
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, […]
Abstract: Galileo Galilei, an astronomer, physicist, and philosopher of the 16th and 17th centuries is credited with the discovery of several scientific instruments and phenomena that contribute further to the understanding of modern science. At the time in Italy, even when religion was dominant, he was one of the primary proponents of scientific innovation over religion. […]

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 […]
Abstract This article builds on previous work on the information paradox, but is independent of any of them. The central idea concerning this article is that gravity is not a fundamental force, rather an emergent force. Though this idea is not new in modern physics, the reasoning followed in this paper is unique. The logical […]
By Katie Bean There is an undeniable sense of wonder felt when we look up at the sky and see the clouds. Wisps and stretches of cotton wool; you only have to skim read Romantic literature or gaze at a few pieces of art to understand and acknowledge their captivating, obvious beauty. They are also […]
The discovery of the Higgs boson is only the beginning when it comes to uncovering various mysteries about our universe. Currently, there is a lot of research on the possible link between the Higgs mechanism and cosmology. In this article, the topics of inflation, the false vacuum, dark matter, matter-antimatter asymmetry and what role the […]
Abstract: The objective of this article is to explore the existing efforts in the study of replicating the Morpho butterfly’s structural color in order to create artificial colorings that may be longer lasting and more environmental-friendly which has the potential to offer a better way to color various products. The article gives an overview of […]
Shriya Subramanian Abstract Nuclear medicine is a medical specialty that makes use of radiation in two primary areas of medicine: the diagnosis and the treatment of disease. There are various techniques used for diagnosis such as Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET), which are collectively known as nuclear imaging. The […]
Introduction The study of physics has captured the human mind for centuries. Encompassing some of the greatest minds of history, the evolution of physics has followed the human race since the beginnings of civilization. Filled with both complementing and contrasting thought experiments, theories, and revelations, the journey to modern-day physics is an exciting and complicated […]
By Waania Zia Abstract This is an article detailing the different models and theories of time travel, focusing on Einstein’s theory of relativity and Minkowski space-time, which is the combination of the 3 dimensional space with a 4th dimension of time. It delves into the development of time travel within science and fiction as well […]
Forces A force is something which tends to change the state of rest or state of motion, or size, shape, the direction of motion of a body, etc.. There are four fundamental forces: gravitational, electromagnetic, strong nuclear and weak nuclear forces. These forces are responsible for all possible interactions that can take place in this […]
Abstract This paper explores different types of rocket propulsion systems and assesses their benefits and drawbacks. The paper also compares different types of rockets, such as Single Stage rockets and Two Stage rockets, before proposing a propulsion system for a future Single Stage to Orbit (SSTO) rocket. This system shall meet the requirements of both […]
Abstract: The following article concerns the James Webb Telescope Cosmic Mining Project (offered by the Institute for Research in Schools), undertaken by a group of students in Abingdon School. The project focuses on the classification of the spectra (showing the intensity over a range of electromagnetic wavelengths) of stars and galaxies identified by the Spitzer […]
Abstract Ever since the proposal of the Big Bang model, scientists have been puzzling over the expansion rate of the universe. What is the current speed of expansion? Is our universe expanding at an accelerating or decelerating rate? What does this tell us about the substances in the universe and our ultimate fate? In this […]
