Knowledge and use of basic mathematics have always been an inherent and integral part of individual and group life. Refinements of the basic ideas are visible in mathematical texts originating in the <a title="Egyptian mathematics" href="http://en.wikipedia.org/wiki/Egyptian_mathematics">ancient Egyptian</a>, <a title="Babylonian mathematics" href="http://en.wikipedia.org/wiki/Babylonian_mathematics">Mesopotamian</a>, <a title="Indian mathematics" href="http://en.wikipedia.org/wiki/Indian_mathematics">Indian</a>, <a title="Chinese mathematics" href="http://en.wikipedia.org/wiki/Chinese_mathematics">Chinese</a>, <a title="Greek mathematics" href="http://en.wikipedia.org/wiki/Greek_mathematics">Greek</a> and <a title="Islamic mathematics" href="http://en.wikipedia.org/wiki/Islamic_mathematics">Islamic</a> worlds. <a title="Axiom" href="http://en.wikipedia.org/wiki/Axiom">Rigorous arguments</a> first appeared in <a title="Greek mathematics" href="http://en.wikipedia.org/wiki/Greek_mathematics">Greek mathematics</a>, most notably in <a title="Euclid" href="http://en.wikipedia.org/wiki/Euclid">Euclid</a>'s <a title="Euclid's Elements" href="http://en.wikipedia.org/wiki/Euclid%27s_Elements">Elements</a>. The development continued in fitful bursts until the <a title="Renaissance" href="http://en.wikipedia.org/wiki/Renaissance">Renaissance</a> period of the <a title="16th century" href="http://en.wikipedia.org/wiki/16th_century">16th century</a>, when mathematical innovations interacted with new <a class="mw-redirect" title="Scientific discoveries" href="http://en.wikipedia.org/wiki/Scientific_discoveries">scientific discoveries</a>, leading to an acceleration in research that continues to the present day.<a title="" href="http://en.wikipedia.org/wiki/Mathematics#cite_note-5">[6]</a><br />Today, mathematics is used throughout the world in many fields, including <a title="Natural science" href="http://en.wikipedia.org/wiki/Natural_science">natural science</a>, <a title="Engineering" href="http://en.wikipedia.org/wiki/Engineering">engineering</a>, <a title="Medicine" href="http://en.wikipedia.org/wiki/Medicine">medicine</a>, and the <a class="mw-redirect" title="Social science" href="http://en.wikipedia.org/wiki/Social_science">social sciences</a> such as <a title="Economics" href="http://en.wikipedia.org/wiki/Economics">economics</a>. <a title="Applied mathematics" href="http://en.wikipedia.org/wiki/Applied_mathematics">Applied mathematics</a>, the application of mathematics to such fields, inspires and makes use of new mathematical discoveries and sometimes leads to the development of entirely new disciplines. Mathematicians also engage in <a title="Pure mathematics" href="http://en.wikipedia.org/wiki/Pure_mathematics">pure mathematics</a>, or mathematics for its own sake, without having any application in mind, although applications for what began as pure mathematics are often discovered later.<a title="" href="http://en.wikipedia.org/wiki/Mathematics#cite_note-6">[7]</a></div></div>vahid darvishhttp://www.blogger.com/profile/02245465765987821526noreply@blogger.com0tag:blogger.com,1999:blog-4152364821328761402.post-64238174679014540632008-05-02T23:50:00.000-07:002008-05-07T02:22:45.714-07:00test<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-czPpcXT7VRaDqNx9EUrn4ZBlKC4ewvsQdtLjNgTuIN576aDr0h1Fw02LZjg-9CrB0mm0ubfBkmVVXa6-qqa-wy0J80TPKaQh_zmiTyn9Wft1YwJiHp-tQe7oF53R67JIhxVitGm4rTE/s1600-h/3208757269.jpg"><img id="BLOGGER_PHOTO_ID_5196040820021172290" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 162px; CURSOR: hand; HEIGHT: 113px" height="238" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-czPpcXT7VRaDqNx9EUrn4ZBlKC4ewvsQdtLjNgTuIN576aDr0h1Fw02LZjg-9CrB0mm0ubfBkmVVXa6-qqa-wy0J80TPKaQh_zmiTyn9Wft1YwJiHp-tQe7oF53R67JIhxVitGm4rTE/s320/3208757269.jpg" width="322" border="0" /></a><br /><div></div>vahid darvishhttp://www.blogger.com/profile/02245465765987821526noreply@blogger.com1
