M. Stanley Whittingham : Pioneer on Rechargeable Lithium Battery

Image
 M. Stanley Whittingham is a well-known scientist and researcher who has made significant contributions to the creation of lithium-ion batteries. He was born in the United Kingdom on December 22, 1941. Whittingham's seminal work on rechargeable lithium batteries began in the 1970s, while he was employed with Exxon Research and Engineering Company. His study concentrated on developing a high-energy-density battery that could effectively store and discharge electrical energy. Whittingham's research resulted in the discovery of intercalation, a technique that allows lithium ions to be introduced and withdrawn from the atomic layers of specific materials. This breakthrough paved the way for the creation of lithium-ion batteries. Whittingham was awarded the Nobel Prize in Chemistry in 2019 along with John B. Goodenough and Akira Yoshino in appreciation of his pioneering achievements. The Nobel Committee recognized their efforts in developing lithium-ion batteries, which have revolut

Ernest Rutherford

Image
 Ernest Rutherford, better known as Lord Rutherford of Nelson, was a well-known New Zealand physicist. He is widely considered as one of the best nuclear physics experimenters of all time. Rutherford contributed significantly to our understanding of atomic structure and radioactivity. Rutherford presented the Rutherford model of the atom in 1911, which stated that the atom contains a tiny, compact, positively charged nucleus at its center, with electrons surrounding it. This concept transformed the conventional view of the atom and established the groundwork for the creation of the current atomic theory. Rutherford is also famed for his gold foil experiment, which he carried out in 1909. Rutherford and his colleagues attacked a thin sheet of gold foil with alpha particles and examined the scattering patterns. Rutherford concluded from the surprising results that atoms possess a concentrated, positively charged nucleus that comprises just a small proportion of the atomic volume.  Ruther

War of the Currents: The Rivality between Edison Vs Tesla

Image
 The "War of the Currents" was a time in history in the late nineteenth century when there was fierce competition between two competing electrical power systems: Thomas Edison's direct current (DC) system and Nikola Tesla and George Westinghouse's alternating current (AC) system. Thomas Edison pioneered the use of direct current (DC) electricity for electrical distribution through his firm Edison Electric Light firm (later known as General Electric or GE). Due to its restricted transmission capabilities, DC electricity travels in just one way and necessitates power plants being situated near customers. On the other side, Nikola Tesla, with the financial backing of George Westinghouse, lobbied for alternating current power. AC electricity allows for more efficient long-distance transmission and the use of transformers to step up or step down voltage levels as needed. As each side sought to control the burgeoning electric power business, tensions between these two syste

Big Pharma Conspiracy

Image
 The term "Big Pharma conspiracy" refers to the widespread idea that pharmaceutical firms engage in clandestine and immoral practices in order to maximize profits at the expense of public health. While it is true that the pharmaceutical business is profit-driven, valid concerns regarding corporate practices must be distinguished from unsubstantiated conspiracy theories. Consider the following crucial points:     Research & Development: Creating new pharmaceuticals is a time-consuming and expensive process that requires considerable research, clinical trials, and regulatory clearance. Pharmaceutical businesses devote enormous amounts to research and development (R&D) in order to identify and commercialize new medications. While profit is a motivator, it is also vital to recuperate the significant expenditures of R&D and to support future innovation. Patent protection is obtained by pharmaceutical corporations in order to preserve their investments in medication d

Erwin Schrödinger: The man who change the physics

Image
 Theoretical biologist and Austrian physicist Erwin Schrödinger made substantial contributions to the study of quantum mechanics. He was born in Vienna, Austria, on August 12, 1887, and passed away there on January 4, 1961. The Schrödinger equation, which explains the behavior of quantum particles, is the most famous formulation of the wave equation created by Schrödinger. In 1925, he created this equation as an alternative to Werner Heisenberg's matrix mechanics version of quantum theory. A fundamental equation in quantum physics known as the Schrödinger equation describes how a physical system's wave function changes over time. The wave-particle duality, in which particles can have both wave-like and particle-like features, is mathematically described. The probability of various outcomes of quantum experiments may be calculated using the wave functions, which are the solutions to the Schrödinger equation. The "Schrödinger's cat" thought experiment is one of Schr

Albert Einstein: The Genius

Image
 The theory of relativity, developed by renowned scientist Albert Einstein, revolutionized how we think about space, time, and gravity. His birthday was March 14, 1879, and he passed away on April 18, 1955, in Princeton, New Jersey, in the United States. He was born in Ulm, in the Kingdom of Württemberg, in the German Empire. The special theory of relativity and the general theory of relativity are the two main parts of Einstein's theory of relativity.  The famous equation E=mc2, which represents the equivalence of mass (m) and energy (E), was first proposed by the special theory, which was published in 1905. This theory demonstrated that the rules of physics are the same in all inertial reference frames. Published in 1915, the general theory of relativity expanded on the special theory and offered a fresh perspective on gravity. In accordance with this theory, mass, and energy produce the curvature of spacetime, not gravity, which is a force. It explains phenomena like gravitation
