Transparency of Atomic and Subatomic Particles Have you ever wondered whether atomic and subatomic particles are transparent? If not, then why aren’t we able to see particles of nitrogen and oxygen in the air? In this article, we will explore the transparency of atomic and subatomic particles and find out if they can be seen …

Metronomes are common tools for musicians to maintain a consistent tempo while playing an instrument. These tools work on the principle of a weighted pendulum, where a weight moves back and forth, producing a clicking sound with each oscillation. A metronome typically allows a wide range of tempos, between 40-208 beats per minute (bpm) in …

Specific Heat Ratio: A Beginner’s Guide to Rocket Propulsion If you’re interested in rocketry, you may have come across the term “specific heat ratio.” But what is a specific heat ratio, and why is it important in rocket propulsion? Defining Specific Heat Ratio Specific heat ratio is defined as the ratio of the heat capacity …

There are various assumptions that one can make to simplify the equation of radiation transfer given in (1.1). In this article, we explore some plausible and creative assumptions for modelling radiative transfer of heat from the atmosphere to terrestrial solar cells. Introduction The equation of radiation transfer given in (1.1) describes the transfer of radiant …

Guns are often associated with loud noise, power, and aggression. While they’re useful in certain situations, they can be quite disturbing for others, especially if they’re used in populated areas. However, there is a way to muffle the sound of a gun, making it less disturbing. This is where gun silencers come in. A gun …

One Electron Energy Levels Explained If you have been reading a book on quantum transport by Supriyo Datta, you might have come across the concept of one-electron energy levels. Specifically, you might have read that “For the ionization levels, the one-electron energies εn represent the difference between the ground state energy EG(N) of the neutral …

When it comes to designing cooling and ventilation systems, one important aspect is determining the capacity of the fan needed to achieve the desired airflow rate. However, as we go higher in altitude, air density decreases, which can affect the performance of the fan. This raises the question, is there a way to estimate fan …

As architects and engineers continue to push the limits of skyscraper design, the question of how tall a building can theoretically be has become an increasingly intriguing subject. The limitations of building size are not only determined by human factors like transportation and air density, but also by the physical constraints of materials and the …

The Electromagnetic Spectrum: Understanding Light The study of electromagnetism is essential to understanding the fundamental workings of our universe. At the heart of this complex yet thrilling branch of physics lies the phenomenon known as light. Light is known for having electric and magnetic fields oscillating perpendicular to each other. But what causes these fields …
