funding for this program game of ice hockey scoring three goals in one game is called a hat trick China Patrick today is solve a problem in field theory that Isaac Newton seems to have a great day known as gases turn on imagine Nation genius name Michael Faraday this life would have been embarrassed emoji he began to circumstances and he had very little formal education to become a book binder he was intent on self-improvement then he started attending institution in London and he was and he and he eventually as the professor in the most famous scientist in all of Europe his career are they understood the scientific and yes he has intuition every scientific problem it is one of the greatest ideas that situation that we want to speak about today everywhere throughout space Shirley no true has dug up more scientific truth and the sharps faded fairy the groundwork from which much of modern physics mathematical in nature not alone electric force is inversely proportional to the square of the distance between the charges experiment what concept the idea of the inverse Square relations Century earlier in fact Isaac Newton's Theory stated that the form of an apple consequences of the same basic laws universal gravitation this was a difficult to reply Steven for Isaac Newton answer the point is have to show the gwinin objects attracted to the Earth all of the Earth more concentrated at the center analyze what he called action at a distance even though they're separated by millions of kilometers with no tangible connection between them might have come to admit a certain dissatisfaction with the idea of action-at-a-distance defensively in the principia I have not been able to discover the cause of those properties of gravity hypothesis but that famous phrase I say null hypothesis physical or mechanical meat and that's according to the laws which we have explained obviously in England there after the law of gravitation was the law of the land and by the 19th century discovered obey Summerville divorce decreases with the square of the distance similarity is amazing question perhaps because the inverse Square law is related to perhaps because these forces are the only things that diminish with the square of distance Square Mall equally in all directions subscribe down hemisphere area of a sphere grows as the square of its radius per unit area decrease as the square of the distance the inverse Square law wasn't the only provocative ideas which Faraday was exposed by 1810 he was a regular visitor particularly actors of the institutions legendary Professor sir humphry Davy natural philosopher president of the Royal Society he was The Very Best of British slang with his own research shows list Davis Polk is the world's Authority on every element from sodium to potassium chlorine to iodine Baby the game of scientific father figure for Thursday almost 20 years relationship was Rocky 1 but under Davies and phones in the Golden Age of chemistry who discovered Benzene liquefied chlorine gas and develop new allies of Steel a list of is remarkable accomplishments as a camera skills on and on 1821 Faraday set aside is working chemistry in that year discovered the effect electric currents has on magnets that effect can be seen clearly now in 1821 it was still a great scientific mystery Indy why would the compass needle line up perpendicular to the electric current Spark by curiosity scientific confusion Faraday set out to solve the mystery for himself of an electrical current and invented the device to do it that device happened to be the first electric motor how did Michael Faraday management that's because being unable to analyze the mathematical Saturday was able to take these circular magnetic forces at face value did Michael Faraday electricity as well as magnetism applied real forces in space began his study of them with a number of assumptions anywhere in the vicinity of an electric charge a small test charge experiences of if it's due to only one charge the pattern of forces detected by the test charge is simple BrandsMart for two opposite charges four four two charges of the same sign and more complex still for more complicated arrangement but in any case here's the point even if the test charge isn't there to feel it I don't know forces Can Be Imagined to exist everywhere in space is the essence of the idea of the few fuel can also be expressed mathematically horse's  on a test charge at each one is equal to the test charge times a quantity definition of the electric field phenomena has forces in space you manage to see further than his peers as a result of this any other discovery can the professor there as well as a member of the Royal Society into the invisible forces of space the one over r squared force between electric charges suggested that the force must be applied by something radiating outward from charges the Sun never stops and never ends in space imagine this something would be lines or two applying a force to any charge and its path these lines of course only on positive charges never Crossing the configuration the charges would have a characteristic pattern of lie and weak far from the Chargers where the lines are farther apart to apply for Isaac each point in space and the force arises from the intensity of the line regardless of the location of the charges that create them even without such face are you driving this is how a faraday picture of the electric field and it still seems the most graphic way to visualize Define scientific community necessarily those steps would be mathematical was taken by Carl Friedrich Gauss astronomer perhaps the best mathematician of all time Elsa's mathematics would offer An Elegant to Faraday's idea and it would become law is represented by all over lines of force passing through any surface is proportional to the inside charge inside a circle positive flux outwards must be balanced by an equal amount of energy more negative plus Gus's ball which is mathematical definition to Faraday's intuitive about the electric field is actually an expression of the geometric meaning of any inverse Square law free p*** it applies not only to electric field magnetic fields as well flowing from the Sun in any event houses theoretical work parodies common sense reveals the number of amazing facts about nature itself example Watch What Happens inside a conductor cost of a moving electrons passing through a conductor horses the electrons to flow the electric field inside a conductor therefore 0 equal to 0 and since all the actions at the circus metal box of any sort Electric Feel that can be demonstrated with this device electric charge microscopes Inside the Cage When the boxes and close the gold leaf any metal box Kindle any metal box that does do it it's called a faraday cage of course not every Faraday cage was designed to protect its contents from electric field probably couldn't care less because radio waves are a kind of disturbance in the electric field Indian clothes container that its name implies a great place to get food reception outside again just about anywhere where can the lines of a uniform sphere of charge go extended Regional charge might consist of many point charges and see if the electric field has only one difference electric field outside inverse Square nature of the Earth concentrated Isaac Newton had to use his most powerful mathematics to prove that point which may have contributed to the publication of the principia Michael Faraday's Vivid mental picture the reason behind the idea can be perceived as completely grasp without any mathematics after all in the end will be the mathematical expression of James Clark Maxwell Saturday would come to admire Maxwell property responding to a letter from Faraday Maxwell Road you are the first person in whom the idea of bodies acting at a distance has arisen as a principal to be actually believed in nothing is clear descriptions you seem to see the lines of force curving around obstacles and driving from as conductors certain directions and carrying with them everywhere the same amount as the lines widen for contract I'm thinking of gravity as well as ice your lines of Force Cross the sky the stars in their courses and so far they had this idea about space what's the weather and then Along Came James Clark Maxwell and he transmuted Faraday's idea into our modern view of the electric field and once I was done Saturdays and so a reasonable question you might ask is something we no longer believe to be true perspective on that question by considering something in today science atom is made up of small particles called protons and neutrons we can smash the nucleus stop the protons and neutrons and study them Awesome song from cells are made up of even smaller constituents it turns out that it's impossible to smash up rope on a pot and get out the individual cross and so the question real that question is very similar to the question of whether Faraday's lines of force or real may turn out to be irrelevant Vines of course we're kind of mental scaffolding that have to be put up the final edifice which was the electric field what's the building is finished someday situation today turn out the TV and the idea of quarks wish today scientists certainly believe are real turned out to be also just the kind of mental scaffolding we'll get on with studying the final when we meet here again next time funding for this program was provided by the Annenberg cpb project you
