#Ferranti #Current war #AC

Icons of EE: Sebastian Ziani de Ferranti

The name Ferranti has been notorious in electrical engineering history until Ferranti International P.L.C. finally went bankrupt in 1993, after having experienced over a century of business. This article will reveal the achievements of a very important player in the Current War, although he did not appear in many of the media at the time. Ferranti was less a man of drama, he rather let his inventions speak for themselves. ...

Icons of EE: Harold P. Brown

Although the War of Currents might seem a classic feud between Edison and Westinghouse, both Army Generals had their lieutenants. For Westinghouse, Nikola Tesla was an important player because of his advancements in alternating current inventions. Edison was far from alone in his fight, receiving unofficial cooperation from Harold P. Brown, feared by many as “The Executioner”. Brown rose when the competition was getting ever more heated, when Edison needed him the most. ...

The 19th century was host to some of the largest scientific advances. Hence it is only fitting that, within the topic of Icons-of-EE, we focus on perhaps the largest topic, the electrification of the world. The previous article introduced George Westinghouse, a proud American and provocateur of AC-power. His War of the Currents was originally driven by the need to light up the world. But the availability of electricity also provided the means for other applications. ...

Science and engineering are great, as long as they are used. Think of vaccines, which lose their value when fewer people make use of them. That is why this article on another icon of Electrical Engineering heroes not necessarily a man known for his inventions, but for his propagation of other men’s ideas. The 19th century was host to some of the largest and most useful developments in physics, electronics and science in general. ...

Icons of EE: Oliver Heaviside

In the last edition of ‘Icons of Electrical Engineering’ we met Richard Feynman (See Vonk 37-3). Among other things, he is famous for the creation of ‘The Feynman Lectures on Physics’ which are commonly used to lecture students on a wide variety of physics subjects including electrodynamics. As you all (will/should become to) know, electrodynamics can be described by the four Maxwell equations. However, James Clerk Maxwell derived a total of 20 equations with 20 unknowns to describe this part of physics. ...

Icons of EE: Richard Feynman

After following module 4, you probably wondered, “why is there an image of Feynman playing the drum on page one?” Well, you’re in good company, he didn’t get it either. Richard Feynman was, however, an avid drummer. He was also a safe cracker, a nude model painter and a world-renowned lecturer. Oh, and he also won a Nobel Prize in physics, but, considering his personal life, one could argue that’s not his biggest achievement. ...
