I've talked on the podcast about launching a worldwide campaign to require the reversal of ALL those little arrows on the symbols for transistors and diodes. You see, they are saying that electricity flows from the positive to the negative. Engineers apparently got that idea from Ben Franklin, and they are sticking with it. It is time for a change! Reverse the arrows! Down with CCF! Viva Electron Flow! Let's tell the truth! This morning Bob Crane W8SX sent me this very interesting article on this topic from Nuts and Volts: http://www.nutsvolts.com/magazine/article/which-way-does-current-really-flow?utm_source=Newsletter+%2332&utm_campaign=Newsletter+%2332&utm_medium=email The article describes very well the origins of this controversy. (There were one or two scary moments in which I thought the author was getting ready to tell us that positive ions can move through wires and transistors (NO!) but he pulled back from the brink and clarified that he was talking about ion flow in electro-chemical batteries. Whew, that was scary!) But here's a question for the philosophers and historians of electronics: When physicists decided to label the electron as "negative" this was an arbitrary choice, right? They could have just as easily decided to call it "positive" with the protons being called "negative" right? In this case all the arrows in our diagrams would not be in need of reversal, right?
In response to popular demand, "SolderSmoke -- Global Adventures in Wireless Electronics" is now available as an e-book for Amazon's Kindle.
Here's the site:
For the print version:
For shipping from a printer in the U.S. (probably better for N. American buyers) Click here: SolderSmoke USA Version
For shipping from a printer in the UK, Spain, or the USA (probably better for UK and other European buyers)
Click here: SolderSmoke EU Version
The two versions are identical, except for a minor difference in the paper used. That's why the prices are a bit different.
