Radio Shack brand may return online
The Radio Shack stores played a big role in my childhood. My first memory of Radio Shack is from around 1975 when I was six. I went with my dad when he bought new speaker cables. We went others times whenever our TV stopped working. Dad would take the back cover off, pull out some vacuum tubes, and take them in to Radio Shack to use the tab tester. Sometimes there would be a line for the tester. If the tester said a tube was weak, dad would go over to a counter and ask the man there for a new one.
How Stocks Work
Wall Street, NY in 1867
For many years nobody could explain to me the rational basis of the stock market. They told me that prices were controlled by the law of supply and demand. Investors expected the the price of shares in successful companies to rise and so they bought them. This demand then drove the price up. Those who got in early enough would make money when they later sold their appreciated shares. This is all true, but it did not answer my question: why do shares have value in the first place.
Review of the Sun Joe CJ603E Wood Chipper
Ever since I first saw them in a catalog years ago I have wanted own one of those garden waste chippers. Those I saw 30 years ago were made of metal and cost far more than I could justify paying. But consumer goods are getting cheaper and home wood chippers are no exception. One reason they are cheaper is that the stamped and folded bodies of heavy-gauge sheet metal have been replaced by molded plastic. Still the prices seemed too low for a useful machine. Surely they would break and jam unless the openings had been made deliberately small enough that nothing which would put a strain in the mechanism could be inserted in which case the machine would be of little practical value.
Where Did Sputnik Get its Name?
On October 5, 1957, the Soviet newspaper Pravda announced that the Soviet Union had launched a 184 pound object into Earth orbit. That first artificial satellite has since come to be known in the English-speaking world as Sputnik. In the West it is now widely assumed that the Soviets chose the word sputnik as the name for their satellite because it means “fellow traveler.” This is not what actually happened.
