The Accounting Equation

accounting equation example

Accounting equations’ discretion starts from the assets and liabilities. Mathematically speaking, the equity is the difference between the value of its assets and that of its liabilities:

Assets - Liabilities = Capital

In addition, you can increase the share by revenue and decrease with the outputs. This make sense that when you get a check you become "rich" and when you pay for heaving lunch you become "poor". Mathematically this concept is expressed the Accounting Equation:

Assets - Liabilities = Capital + (Revenu - Expenses)

The equation always be respected; This is true whether the movements of money are always made from one account to another.

 For example, if you receive the money as revenue, there is a corresponding increase in capital. Another example, you may have an raise in assets if it corresponds to an increase in liabilities.

Invention Of The Light Bulb

Invention Of The Light Bulb

Do you know who invented the light bulb? Sure, most will say, Edison was, But that's not true.. Although Thomas Alva Edison in 1879 developed a carbon-filament lamp and started with this light bulb industrial mass production. The press then announced the invention as a sensation - but because it was actually a quarter of a century old. A native of Germany, watchmaker Heinrich Goebel had in fact in 1854 brought the first usable light bulb with a carbonized bamboo fiber glow. A court later stated that he was the real inventor. Only he did not let his idea patented.

Heinrich Goebel, born 1818 in Springfield am Deister, he was a very bad student. However, he attested to his teacher in the final certificate in 1832 an "inventive mind". Goebel learned watchmaker, opened a shop for mechanics and optics and always spent a lot of time in his workshop to tinker with arc and incandescent lamps. In 1848 he immigrated with his wife and two children to America and had in New York again watch making and optics business.

 He continued his experiments continue with the bulbs and finally found the right material for the filament. Supposedly his cane to have brought the idea to put a charred bamboo fiber in a 4711 bottle of Eau de Parfum him. With a mercury venting he created a vacuum inside the glass bulb and prevented the burning out of the thread. Goebel further tinkering on his invention and should have been reached in 1859 with its lamps burn time of 400 hours. He lit so that his shop window. But that was said to be so bright that the neighbors complained and Goebel had to reduce the lighting again.

1879 Edison then tinkered on the principle of light bulb and set out on the intensive search for a suitable filament. 2000 materials he allegedly tested until he tried it with a charred cotton thread. Its bulb burning for 40 hours. Meantime Werner Siemens invented the dynamo, so that these bulky batteries were no longer necessary to generate electricity, which had to be charged by huge exciters again in Germany. The bulb could be put on the market.

Role Of Calcuim In Human Body


Process of transformation of calcium, chemical element of fundamental importance for the human organism, in which it is present in abundance, since it performs functions of mechanical support in the bone tissue in the tissues of the tooth and its presence is also essential for the activity of enzymes and for the normal unfolding of various functions, such as muscle contraction by mediating the release of acetylcholine and therefore the transmission of the pulse. 

The transmission of nerve impulses, clotting .The vitamin D promotes the absorption of calcium through the intestinal mucosa and favors the deposition of calcium salts in the bone tissue other vitamins that interfere in the metabolism of c. are vitamin A and vitamin C. In pathological conditions, a decrease in the concentration of calcium ions in the plasma leads to an increase of the neuromuscular excitability and a syndrome called tetania.



Crystallization is the process of hardening, which leads to the formation of crystals.
It can be made from a solution, melt, the gas phase, an amorphous solid or from another crystal (re crystallization), but always through crystal formation and crystal growth. In this process, crystallization heat is released.

This results in a crystal can form the material must first be brought into super saturation. This is done for example by cooling processes from solutions or melts, or by evaporation of the solvent.

For crystalline materials, which consist of several components (for example, ionic crystals), the super saturation can also be prepared by mixing two solutions, each containing one of the components.
Here, the previously dissolved molecules or elements arranged in a regular, partly substance-specific form. This process can be accelerated if seed crystals are added, which then grow in the super saturated solution. The crystals can then be separated by filtration, flotation, and centrifugation or sieving of the solution (see also separation process). An example of obtaining a mass product by 
crystallization is the extraction of salt in salt pans.

The concept of crystallization is also used in a figurative sense, if a / someone something (a situation, a thought, etc.) gradually becomes clearer
