Multiplication method in Vedic Math Multiplication: Numbers are close to the base. The following steps are followed: Step I: write the numbers and their deficit Step II: Any product will have two parts and so Right part will consist of Product of both deficits and left part would consist of cross subtraction of either of […]

# Graphing and Scientific Calculator

I wanted to share two great resources that almost any Math student will appreciate. An Online Scientific Calculator and a Graphing Calculator. Both are free, work directly in your browser and have a wide range of features including graphing up to 5 equations, calculating permutations and statistical regressions and multiplying matrices, to name just a […]

# More of Vedic math

Let us do some verification of calculations and especially multiplications (product of two numbers) The correctness of any arithmetic operation can be verified by carrying out the same operation on the navasesh of numbers in the operation. Now what is navasesh? Navasesh of a number is “the remainder obtained when the number is divided by […]

# Vedic formulas

The Vedic mathematics from Vedas is an science of calculating faster when there were no calculators and computers and were once used by our ancient scholars to make mathematical calculations faster . These are one line formulas or what we know it as sutras which not only enrich the computational skills but also provide a […]

# Plastids

Plastids Plastids are sub-cellular self-replicating organelles present in all living plant cells, and the exclusive site of many important biological processes, the most fundamental being the photosynthetic fixation of CO2 within chloroplasts, a process which is vital to life on earth. In addition, plastid metabolism is responsible for generating economically important raw materials and commodities […]

# Central Dogma

Central Dogma of Molecular Biology Virtually everyone knows that the genes, located in the nuclei of all cells of the body, control heredity from parents to children, but most people do not realize that these same genes also control day-to-day function of all the body’s cells. The genes control cell function by determining which substances […]

# Tyndall effect and nature

Sunsets: When the air is clear the sunset will appear yellow, because the light from the sun has passed a long distance through air and some of the blue light has been scattered away. If the air is polluted with small particles, natural or otherwise, the sunset will be redder. Sunsets over the sea may […]

# Haber’s process

Haber’s process: The chemical equation denoting the synthesis of ammonia from its elements is, N2 (g) + 3H2 <=====> 2NH3(g) The description of above reaction is: it is a gas phase reaction, a reversible reaction, an exothermic reaction in which number of moles decreases upon the formation of products from reactants. Four moles of reactants […]

# Hydrogen Bonding

Hydrogen bond: “The electrostatic forces of attraction between a partially positive charged hydrogen atom of a molecule and a highly electro-negativity atom are known as hydrogen bond. Hydrogen bond: “The electrostatic forces of attraction between a partially positive charged hydrogen atom of a molecule and a highly electro-negativity atom are known as hydrogen bond. In […]

# Weather pattern and thermodynamic rules

Thermodynamics involves the study of heat to work transformations. The weather and climate on the earth is a result of absorption of solar heat by land, air and water on the earth and heat exchanges and heat to work transitions between them. Weather patterns The Earth receives energy from the sun, moon and other stars. […]
