In physics, waves refer to disturbances in a medium carrying energy without a net movement of particles. The two most common types of waves are electromagnetic and mechanical waves. Both transmit information, energy, and momentum, but they do not...
The past two centuries have produced some of the most incredible inventions ever developed in human history. Many significant ones came to life in America. From vaccines and medicines to electronic devices and deep space exploration, many American...
Benjamin Franklin gets all the credit for discovering electricity, but all he did was establish a link between lightning and electricity. Charles François Fay, Luigi Galvani, Alessandro Volta, Michael Faraday, Thomas Edison, and Nikola...
Phosphoric acid is a corrosive inorganic acid with the chemical formula H3PO4. It’s a weak acid, available in a range of quantities, purities and reagent grades. In its pure form, phosphoric acid is a colorless solid. In less concentrated...
A British physicist named Ernest Rutherford described alpha particle for the first time in 1899. He also differentiated and named alpha and beta radiation. However, it wasn’t until 1928 that George Gamow solved the theory of alpha decay using...
Radiation can be defined as the energy that travels through space or through a material medium in the form of particles or waves. Depending on the energy of the radiated particles, radiations can be categorized into two groups: Ionizing radiation:...
The word “catalyst” is derived from the Greek word katalyo, which means “to pick up,” or “to unite,” or to annul.” The concept of the catalyst was first described by chemist Elizabeth Fulham in 1794...
Anyone with the basic understanding of cosmology is aware of the certainty that, sometime in the distant future, our Earth will die. But the question is how and when. The death of the Earth can be explained in two ways; biologically and geologically...
The new research shows that the origin of photosynthesis in today’s plants had begun nearly 1.25 billion years ago. Previous studies had placed it somewhere between 0.7 and 1.2 billion years. Researchers put “Bangiomorpha...
Researchers achieve detailed high-speed imaging of the microparticle impact process. The study revealed that both the surface and the particle melt to some extent at high impact velocities. The combination of high temperatures...
The new method can use any pliable molecule to write, store, and read data. It is cheaper and less labor-intensive as compared to DNA-based methods. The ‘reading’ averages 20 bits/second while ‘writing’ averages 8...
Different types of sensory instruments are used to determine the location and orientation of an object. The two most common of these instruments are the accelerometer and the gyroscope. When integrated into a signal device, they produce incredibly...
