No. Albert Einstein is usually considered to have been a Physicist.
But in order to do what he did in Physics, he needed to use tons of
high-power mathematics.
mathamatic
Isaac Barrow inveted Mathamatic stuff.
deffrentiation is the branch of mathamatic logic that deal with engineering aspect.in anothe way is graphy method solve gradient of slop.
LOL means Laugh Out Loud Jk means Just Kidding using simple mathamatic techniques i would say its safe to assume that LOLIJK would mean ....... are u read for it .... Laugh Out Lough Im Just Kidding
The significance is that not everything can be expressed with whole numbers. This is especially clear in the case of measurements; a certain unit has been chosen as the standard of length (the meter); the length, width, or height of real-life objects will usually not happen to be an exact multiple of the meter (or close enough to that), so that fractions have to be used.
The one known by most the the self-named Descartes' Theorem, in where it explains the relationship of Four mutually tangent circles. Descartes' first addressed this theorem in a letter to Princess Elizabeth of Bohemia.
The question is a little more difficult to answer than you may think. Here is a link to the mathamatic concept, each pipe is different so you will need the material your using. http://knol.google.com/k/d-gardiner/how-to-calculate-pressure-drop-and/35e6sqhxsbdsg/2# My friend Jeff from Canadian Leak Detection says: The answer is 189 gallons per minute. Then: The rest of the story is that 189 gallons is nozzle flow. If the water flows down the pipe for any distance the friction will slow the flow a bit. So if you need really accurate flow rate I need more info.
