Quantum Tunneling

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 …

Double slit experiment using Arduino and Light sensors

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 …

Applications of General-Purpose Computational Fluid Dynamics to a Plasma Propulsion System

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 …

Observing the Mpemba effect over a range of initial temperatures of bodies of water.

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 …
