“An innovator is one who does not know it cannot be done” - R.A. Mashelkar These splendid words of Dr R A Mashelkar have made a deep-rooted impact on my mind. He rightly states that great leaders fearlessly tackle challenges; they believe that nothing is impossible. These leaders are actually innovators who have immense passion in them to envisage solutions for perplexing problems. As a young, aspiring engineer, I find Dr R A Mashelkar’s philosophy, that the innovators have compassion in their heart
belief that made Max Planck a physics super star was that, “light can be emitted and absorbed only in the form of certain discrete energy packages.” Though, without the monumental work that his predecessors, which include Ludwig Boltzmann, Josiah Willard Gibbs, and James Clerk Maxwell, his work would have been ill inspired as well as impossible! As the book continues the reader learns more and more about Max Planck, including how his work on the Light Quanta led to a better understanding of the
To answer the most obvious question, what is ΔHºrxn·? Well, ΔHºrxn· means the change in enthalpy. To break it down further, enthalpy is the measure of the amount of energy in a system. Every single reaction in the entire universe has a change in enthalpy. Energy is held in each and every single bond that puts together the world we see and live in today. When a reaction takes place and bonds are broken and reconnected, energy has been transferred, and enthalpy tells us how much. It is just about nearly
Le Chatelier’s Principle (i) Biography Born on October 8, 1850 in Paris, France, Henry-Louis Le Chatelier is a French chemist best known for his principle, the Le Chatelier Principle, which has made it possible for chemists to determine and predict the effects of changing conditions on chemical reactions. These changes include, but are not limited to, temperature, pressure and concentration (Clark, 2002). Le Chatelier was the oldest of six siblings in a privileged, Roman Catholic family, which
be related to the microscopic data of individual atoms or molecules (Laurendeau). This ability to make macroscopic calculations based on microscopic characteristics is the main benefit of statistical mechanics over classical thermodynamics. Josiah Willard Gibbs used these definitions to explain the laws of thermodynamics as consequences of the statistical properties of large ensembles of particles, and officially created the field of statistical mechanics. His book Elementary Principles in Statistical
Material science, which is also known as material engineering, is considered an interdisciplinary field and it mainly applies the properties of matters on the earth to a variety of areas concerning science and engineering. In the more advanced stage, the discipline will reach a new scientific field to explore the connection between the structure of materials at the atomic or molecular level and their macroscopic attributes. Moreover, it also includes factors of applied physics and chemistry in which
Whether Einstein Was a Plagiarist or Not Proponents of Einstein have acted in a way that appears to corrupt the historical record. Albert Einstein (1879-1955), Time Magazine's "Person of the Century", wrote a long treatise on special relativity theory (it was actually called "On the Electrodynamics of Moving Bodies", 1905a), without listing any references. Many of the key ideas it presented were known to Lorentz (for example, the Lorentz transformation) and Poincaré before Einstein wrote the famous
