Michael Faraday
<p ><b>Michael Faraday</b>, <a href="http://en.wikipedia.org/wiki/Fellow_of_the_Royal_Society" title="Fellow of the Royal Society" class="mw-redirect" >FRS</a> (22 September 1791 – 25 August 1867) was an English <a href="http://en.wikipedia.org/wiki/Scientist" title="Scientist" >scientist</a> who contributed to the fields of <a href="http://en.wikipedia.org/wiki/Electromagnetism" title="Electromagnetism" >electromagnetism</a> and <a href="http://en.wikipedia.org/wiki/Electrochemistry" title="Electrochemistry" >electrochemistry</a>. His main discoveries include those of <a href="http://en.wikipedia.org/wiki/Electromagnetic_induction" title="Electromagnetic induction" >electromagnetic induction</a>,<a href="http://en.wikipedia.org/wiki/Diamagnetism" title="Diamagnetism" >diamagnetism</a> and <a href="http://en.wikipedia.org/wiki/Electrolysis" title="Electrolysis" >electrolysis</a>.
Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the <a href="http://en.wikipedia.org/wiki/Electromagnetic_field" title="Electromagnetic field" >magnetic field</a> around a <a href="http://en.wikipedia.org/wiki/Electrical_conductor" title="Electrical conductor" >conductor</a> carrying a <a href="http://en.wikipedia.org/wiki/Direct_current" title="Direct current" >direct current</a> that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that <a href="http://en.wikipedia.org/wiki/Magnetism" title="Magnetism" >magnetism</a> could affect <a href="http://en.wikipedia.org/wiki/Ray_(optics)" title="Ray (optics)" >rays of light</a> and that there was an underlying relationship between the two phenomena.<sup id="cite_ref-EncBrit_1-0" class="reference" ><a href="http://en.wikipedia.org/wiki/Michael_Faraday#cite_note-EncBrit-1" >[1]</a></sup><sup id="cite_ref-IEEUK_2-0" class="reference" ><a href="http://en.wikipedia.org/wiki/Michael_Faraday#cite_note-IEEUK-2" >[2]</a></sup> He similarly discovered the principle of <a href="http://en.wikipedia.org/wiki/Electromagnetic_induction" title="Electromagnetic induction" >electromagnetic induction</a>, <a href="http://en.wikipedia.org/wiki/Diamagnetism" title="Diamagnetism" >diamagnetism</a>, and the <a href="http://en.wikipedia.org/wiki/Faraday%27s_laws_of_electrolysis" title="Faraday's laws of electrolysis" >laws of electrolysis</a>. His <a href="http://en.wikipedia.org/wiki/Invention" title="Invention" >inventions</a> of <a href="http://en.wikipedia.org/wiki/Electric_motor" title="Electric motor" >electromagnetic rotary devices</a> formed the foundation of electric motor technology, and it was largely due to his efforts that <a href="http://en.wikipedia.org/wiki/Electricity" title="Electricity" >electricity</a> became practical for use in technology.</p>
<p>
As a chemist, Faraday discovered <a href="http://en.wikipedia.org/wiki/Benzene" title="Benzene" >benzene</a>, investigated the <a href="http://en.wikipedia.org/wiki/Clathrate_hydrate" title="Clathrate hydrate" >clathrate hydrate</a> of chlorine, invented an early form of the <a href="http://en.wikipedia.org/wiki/Bunsen_burner" title="Bunsen burner" >Bunsen burner</a> and the system of <a href="http://en.wikipedia.org/wiki/Oxidation_number" title="Oxidation number" class="mw-redirect" >oxidation numbers</a>, and popularised terminology such as <a href="http://en.wikipedia.org/wiki/Anode" title="Anode" >anode</a>,<a href="http://en.wikipedia.org/wiki/Cathode" title="Cathode" >cathode</a>, <a href="http://en.wikipedia.org/wiki/Electrode" title="Electrode" >electrode</a>, and <a href="http://en.wikipedia.org/wiki/Ion" title="Ion" >ion</a>. Faraday ultimately became the first and foremost <a href="http://en.wikipedia.org/wiki/Fullerian_Professor_of_Chemistry" title="Fullerian Professor of Chemistry" >Fullerian Professor of Chemistry</a> at the <a href="http://en.wikipedia.org/wiki/Royal_Institution_of_Great_Britain" title="Royal Institution of Great Britain" class="mw-redirect" >Royal Institution of Great Britain</a>, a lifetime position.
Faraday was an excellent experimentalist who conveyed his ideas in clear and simple language; his mathematical abilities, however, did not extend as far as trigonometry or any but the simplest algebra. <a href="http://en.wikipedia.org/wiki/James_Clerk_Maxwell" title="James Clerk Maxwell" >James Clerk Maxwell</a>took the work of Faraday and others, and summarized it in a set of equations that is accepted as the basis of all modern theories of electromagnetic phenomena. On Faraday's uses of the <a href="http://en.wikipedia.org/wiki/Lines_of_force" title="Lines of force" class="mw-redirect" >lines of force</a>, Maxwell wrote that they show Faraday "to have been in reality a mathematician of a very high order – one from whom the mathematicians of the future may derive valuable and fertile methods."<sup id="cite_ref-MaxwellSciPapVol1_3-0" class="reference" ><a href="http://en.wikipedia.org/wiki/Michael_Faraday#cite_note-MaxwellSciPapVol1-3" >[3]</a></sup> The <a href="http://en.wikipedia.org/wiki/International_System_of_Units" title="International System of Units" >SI</a> unit of <a href="http://en.wikipedia.org/wiki/Capacitance" title="Capacitance" >capacitance</a>, the <a href="http://en.wikipedia.org/wiki/Farad" title="Farad" >farad</a>, is named in his honour.
<a href="http://en.wikipedia.org/wiki/Albert_Einstein" title="Albert Einstein" >Albert Einstein</a> kept a picture of Faraday on his study wall, alongside pictures of <a href="http://en.wikipedia.org/wiki/Isaac_Newton" title="Isaac Newton" >Isaac Newton</a> and James Clerk Maxwell.<sup id="cite_ref-4" class="reference" ><a href="http://en.wikipedia.org/wiki/Michael_Faraday#cite_note-4" >[4]</a></sup> Physicist <a href="http://en.wikipedia.org/wiki/Ernest_Rutherford" title="Ernest Rutherford" >Ernest Rutherford</a> stated; "When we consider the magnitude and extent of his discoveries and their influence on the progress of science and of industry, there is no honour too great to pay to the memory of Faraday, one of the greatest scientific discoverers of all time".<sup id="cite_ref-5" class="reference" ><a href="http://en.wikipedia.org/wiki/Michael_Faraday#cite_note-5" >[5]</a></sup></p>
