Everyone wants success. Some people spend their every waking moment pursuing it, to the detriment of all else. For others, attaining success seems impossible. They conclude that it is destined for a select few. The rest of us are to remain “content with such things as we have”. Having it all is not “in our stars”. However, the above assumptions couldn’t be further from the truth. When you strive for success with the wrong assumptions, you will never reach it. It’s like travelling somewhere with the wrong map. Zig Ziglar says that, “Success is a process, not an event,” “a journey, not a de

Under Hes Wings..........An article in National Geographic several years ago provided a penetrating picture of God's wings.After a forest fire in Yellowstone National Park, forest rangers began their trek up a mountain to assess the inferno's damage. One ranger found a bird literally petrified in ashes, perched statuesquely on the ground at the base of a tree. Somewhat sickened by the eerie sight, he knocked over the bird with a stick. When he gently struck it, three tiny chicks scurried from under their dead mother's wings.The loving mother, keenly aware of impending disaster, had carried her offspring to the base of the tree and had gathered them under

Pauling, Linus Carl (1901-1994), American chemist and physicist, whose investigations into the structure of molecules led to discoveries of how chemicals bond.Pauling was born in Portland, Oregon, on February 28, 1901, and educated at Oregon State College and the California Institute of Technology. He began to apply his insights into quantum physics as Professor of Chemistry at the institute, where from 1927 to 1964 he made many of his discoveries. By devising techniques such as X-ray and electron diffraction, he was able to calculate interatomic distances and the angles between chemical bonds.During the 1930s Pauling introduced concepts that helped reveal the bondi

Thevenin's Theorem Thevenin's Theorem states that it is possible to simplify any linear circuit, no matter how complex, to an equivalent circuit with just a single voltage source and series resistance connected to a load. The qualification of “linear” is identical to that found in the Superposition Theorem, where all the underlying equations must be linear (no exponents or roots). If we're dealing with passive components (such as resistors, and later, inductors and capacitors), this is true. However, there are some components (especially certain gas-discharge and semiconductor components) which are nonlinear: that is, their opposition to cu

Wait For The Brick A young and successful executive was traveling down a neighborhood street, going a bit too fast in his new Jaguar. He was watching for kids darting out from between parked cars and slowed down when he thought he saw something. As his car passed, no children appeared. Instead, a brick smashed into the Jag's side door! He slammed on the brakes and drove the Jag back to the spot where the brick had been thrown. The angry driver then jumped out of the car, grabbed the nearest kid and pushed him up against a parked car, shouting, "What was that all about and who are you? Just what the heck are you doing? That's a new

By definition, a perfect gas is one in which intermolecular forces are neglected. So, along with the assumptions of an ideal gas, the following assumptions are added:1)Neglected intermolecular forcesBy neglecting these forces, the equation of state for a perfect gas can be simply derived from kinetic theory or statistical mechanics.This type of assumption is useful for making calculations very simple and easy to do. With this assumption we can apply the Ideal gas law without restriction and neglect many complications that may arise from the Van der Waals forces.Along with the definition of a perfect gas, there are also two more simplifications that can be made

Oxidation And Reduction Reactions in Organic Chemistry Introduction one of the unique characteristics of carbon is that it has nine stable oxidation states. It should not be surprising that organic chemists have developed reagents that allow them to alter these oxidation levels. This topic presents a survey of some of those reagents. Oxidizing Reagents We have already seen several examples of such reagents in our discussion of the oxidation of alcohols. They are repeated here for the sake of completeness. Chromic Acid This reagent is prepared by mixing sodium or potassium dichromate with sulfuric acid as shown in Equation 1. It is used to oxidiz

Sometimes People Can't Handle Success
"I tried 1000 different ways to find a solution, but 1001st was the best solution" - Thomas Alva Edison, when asked about his experience in inventing the light bulb.
The first question is "What is Success?"
The dictionaries provide various definitions of success as 'an occurrence that accomplishes its intended purpose' or 'a state of prosperity or fame' or 'a realization that a person is successful', but success is broader than what we define. Achieving success means you became famous; you can have enough money to buy the luxuries you longed for so many years, you are being a d

Radioactivity, spontaneous disintegration of atomic nuclei by the emission of subatomic particles called alpha particles and beta particles, or of electromagnetic rays called X-rays and gamma rays. The phenomenon was discovered in 1896 by the French physicist Antoine Henri Becquerel when he observed that the element uranium can blacken a photographic plate, although separated from it by glass or black paper. He also observed that the rays that produce the darkening are capable of discharging an electroscope, indicating that the rays possess an electric charge. In 1898 the French chemists Marie Curie and Pierre Curie deduced that radioactivity is a phenomenon associa

Multiple Choice Questions on Inductance1. An air cored coil of self inductance L has N turns of fine insulated copper wire wound on a former of cross section area A. If the area and number of turns are doubled and the core is a medium of relative permeability 1000, the self inductance of the coil will be (a) 8000 L (b) 4000 L (c) 8×10–3 L (d) 4×10–3 L (e) L Self inductance of a coil is directly proportional to the area of cross section, relative permeability of the core and the square of the number of turns. The answer therefore is 8000 L. 2. A straight air cored solenoid has length 1 m, area of cross se

Electromagnetic Induction (1) A search coil in the form of a plane circular copper loop of 10 turns and diameter 2 cm is held within a magnetic field of 20000 gauss, with the plane of the loop perpendicular to the magnetic field. The resistance of the search coil is 0.1 Ω. If the search coil is withdrawn from the magnetic field in a time span of 0.1s, the total charge (in coulomb) and the average current (in ampere) flowing during this time are respectively (a) 0.1π, 0.5π (b) 0.2π, 2π (c) 0.2π, π (d) 0.1π, π (e) 0.02π, 0.2π The charge ‘Q’ induced in the search coil is given by Q
