If you ask any random person what is the hardest material on Earth, the most likely answer would be diamond. It is fairly common knowledge. But is diamond actually the hardest material or mineral on Earth? We’ll find out in this article. How...
The density (more precisely, the volumetric mass density) of a substance is its mass per unit volume (denoted in kg/m3). It is a unique physical property of an object that shows how tightly matter is packed together that object. Solid materials like...
Thermal energy refers to the energy possessed by an object due to the movements of particles within the object. It’s the internal kinetic energy of the object, which comes from the random movements of the object’s molecules and atoms...
A mixture is a physical blend of two or more compounds. Each compound retains its own characteristics in the mixture. Scientists recognize two types of mixtures: homogeneous and heterogeneous mixtures. In the overview article, we’re going to...
Physics helps us understand how our world works. It studies a very wide range of objects, from the very small (through quantum principles) to the entire universe (through general relativity). The subject not only covers the objects’ behavior...
The new plasma accelerator can generate electron beams with energies up to 7.8 billion electron volts in just 20 centimeters. This is almost double the previous record for energy generated by plasma acceleration (set in 2014). To uncover the...
For years, many influential personalities such as Bill Gates, Elon Musk, Mark Zuckerberg have advised their followers and audiences to read books. For them, books don’t just help people become successful in life, but it also nurtures the...
Research is a detailed, systematic study into a specific problem or concern using various methodologies set by professional fields and academic disciplines. It involves collecting necessary data, documenting critical information, and analyzing and...
The term “scientist” was coined by a philosopher and historian of science, William Whewell, in 1833. However, it wasn’t until the late 19th century that this term came into regular use. A scientist is a professional who makes...
Osmosis is an example of diffusion in which molecules tend to distribute themselves evenly in space. Unlike diffusion, which can take place in all mediums (gas, liquid, and solid), osmosis only occurs in liquids and (very often in) gases. What...
Kinetic energy is the energy of motion: if something is moving, it is said to have kinetic energy. According to classical mechanics, the kinetic energy (E) of a non-rotating object depends on its mass (m) and velocity (v). E = ½mv2 Since energy is a...
Nanomaterials have become a trending area in science and technology. Numerous metal nanomaterials have been extensively studied for a wide range of applications. Among them, gold nanoparticles have been found to be highly remarkable. They have...
