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...
The World Meteorological Organization recognizes more than a hundred different types of clouds. However, they can be categorized into 10 main types based on their overall shape and the altitude where they form. Clouds are classified and named using...
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...
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...
A base, in chemistry, refers to any substance that releases hydroxide ions (OH−) when dissolved in water or an aqueous solution. Many bases, however, don’t readily carry hydroxide ions, but they, too, produce high levels of OH− when...
What makes an acid strong or weak? To answer this question, we first need to look at the definition of an acid. It is a chemical compound that accepts electrons and/or donates (dissociates) hydrogen ions, also known as protons. Therefore, the...
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...
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 of 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...
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...
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...
