FROM SCRATCH SERIES || CHAPTER 2: विद्युत्वृत्त(The electric Chronicles) || Part 3: Electromagnetism and the great synthesis: The Maxwell Equations

 Part 3 || Electromagnetism and the great synthesis: The Maxwell Equations || Next the world saw, the dawn of something called: Electromagnetism . The man who bore the next torch, then, was one with little to no schooling, and no math beyond arithmetic. This man reached to true greatness by teaching himself and propelled to the heights of, not only, intellectual greatness but also spiritual one- He refused knighthood and turned down the presidency of the Royal Society. The man is: Michael Faraday(1791 - 1867) .  Michael Faraday Faraday's primary contributions start from one: Electromagnetic Induction  in 1831. Faraday discovered that: A changing magnetic field (a concept he introduced) induces an electric current in a conductor. He discovered it through his experiments involving two metal coils wrapped around an iron ring -> and the observation that a current is generated in the second coil whenever a current was started or stopped in the first. In essence:  He wa...

FROM SCRATCH SERIES || CHAPTER 2: विद्युत्वृत्त(The electric Chronicles) || Part 2: The fusion of two sciences and the birth of electrodynamics

 Part 2: The fusion of two sciences and the birth of electrodynamics Up until now, Electricity was an isolated study, having nothing to do with magnetism at all, with even the spectacular Mr. Gilbert considering the two forces of nature separate. But this Danish scientist stumbled upon something that was about to change the face of this field of scholarship. The man we're talking about is:  Hans Christian Øersted(1777 - 1851) What happened was, Mr. Øersted was teaching a course on Natural Philosophy and was giving, thus, a demonstration to his students in the University of Copenhagen, Denmark in 1820. During a demonstration regarding the effect electric currents on heating- how electricity passing through a conductor produces heat, he connected a voltaic pile to a platinum wire and then observed- A compass needle lying nearby deflected. He confirmed after multiple repetitions, that this was indeed a result of something magnetic emanating from the electrical wire.  He then...

FROM SCRATCH SERIES || CHAPTER 2: विद्युत्वृत्त(The electric Chronicles) || Part 1: The unit mathematics of electricity - Coulomb's law

Image
 In chapter I, we experienced the origin story of it all. In this one, we are going to cover all the foundational concepts concerning electricity, magnetism and fusing the two- electromagnetism . This ride will comprise less rigor with regards to history on account of the necessity of covering the concepts which are increasingly complex hereon, in a short literary piece.  Part 1: The unit mathematics of electricity - Coulomb's law   The person that would come first in my list in this trail is none other than the person who first mathematized the charge: Charles-Augustin de Coulomb(1736 - 1806) .  Charles-Augustin de Coulomb Coulomb was a French military officer, engineer and physicist. He wrote a series of seven memoirs to the Royal Academy of Sciences in Paris where he formalized his law and derived it using his invention: The Torsion Balance . His memoirs were titled:  See, Newton, till then has already established the relation between gravitational ...

FROM SCRATCH SERIES || CHAPTER 1: वैद्युतकषास्त्र (THE ELECTRICITY महायज्ञ) || PART 12: The Origin of 'Volt'-age: The story of man behind electrical power

Image
 PART 12 || The Origin of 'Volt'-age: The story of man behind electrical power || In Italy, we find our next guy too:  Alessandro Giuseppe Antonio Anastasio Volta (1745 - 1827) This guy, too, was interested in one additional subject: i.e. Chemistry other than physics that is. He accomplished many things:  1. The first of which is the " Electrophorus ". The electrophorus is a manual electrostatic generator invented by him in 1775. This allowed the generation and storage of electric charges over and over again.  2. Also, his most famous invention- The First true battery : The Voltaic Pile . This was capable of producing a continuous flow of electric current through a closed circuit.  Structure of the Voltaic Pile:   The Blotting paper was some eletrolyte like Brine-soaked cloth or cardboard-soaked in saltwater, acid, or alkali.  The individual element was also called a cell .  Although the discharge from this battery did last longer than a spark, th...

FROM SCRATCH SERIES || CHAPTER 1: वैद्युतकषास्त्र (THE ELECTRICITY महायज्ञ) || PART 11: Electricity from Animals- The Frankenstein story

Image
 PART 11  || Electricity from Animals- The Frankenstein story || The next person in our trail did something completely different and something exceptionally fascinating. The unusual nature of this guy's mention would become even more clear after I mention his profession: Physician and biologist. But to be fair, also, a physicist and also a philosopher. With the next person we move, in this study, back to Europe (😑). This man is from Bologna (Then, Papal States; now Italy): Luigi Galvani(1737 - 1798) . Though this guy's work is very interesting and fascinating too, I will, for some reasons, cover it concisely here. For that reason, I am going to source wikipedia and chatGPT for this part.  Luigi Galvani It says that Galvani's interest in " medical electricity " came from the ongoing researches in electricity in Europe in the 18th century and also:  Galvani is credited with the discovery of what is called " animal electricity ". In 1780, using a frog, he ...

FROM SCRATCH SERIES || CHAPTER 1: वैद्युतकषास्त्र (THE ELECTRICITY महायज्ञ) || PART 10: Electricity comes to the Modern World: Ben Franklin's Kite

Image
 Part 10: Electricity comes to the Modern World: Ben Franklin's Kite Welcome to the end of an era and the beginning of a new one. Marked by our next man who completely changed the face of electrical research/study and the terminology and concepts will start feeling more recognizable from this point on. This is the point where the study of electricity moves out of Europe für the first time and into(well, essentially, an extension of the Anglo-Saxon British Empire) a little place called: [Drums rolling.......] --> America .  So, this next man in our trail is, not only gonna be a big name in science, but is also, one of the founding fathers of the United States of America . Yes, you perfectly would've figured out till now... the guy is: [Drums Rolling.....] Benjamin Franklin(1706 - 1790) Ta... Da.....    This is the next BIG MAN right after Mr. Gilbert that is (In my opinion only). As such, Mr. Franklin is more popular in the modern world than any of his predecessors...
