Recently, I was looking for something online, or probably browsing aimlessly, when I happened on a
name I hadn’t thought of since I was a child: Alfred P. Morgan. Someone had uploaded a digitized
version of The Boy Electrician. I was instantly swept back more than half a century to my local library. In
my mind I saw the familiar metal shelving and the blue-gray binding of my favorite book, also written –
and illustrated – by Morgan: The Boys’ First Book of Radio and Electronics.
What is known about Alfred P. Morgan?

Soon enough, say some engineers, miniature wireless sensors will be located in spots where it would be
inconvenient, to say the least, to change their batteries – inside your body, within the steel and concrete
of buildings, in the dangerous innards of chemical plants. But today, even the most robust nodes can be
counted on to last only a few years. Ideally, engineers need wireless sensors that can last forever without
external power sources or battery changes. According to research presented in December at the
International Electron Devices Meeting, in Baltimore, that dream is within reach.
The expression ‘to say the least’ in the text suggests that…

The history of technology is full of breakthroughs in one field that wound up working wonders in a
related one. The 300B vacuum tube, introduced by Western Electric in 1937 to amplify telephone
signals, found a far more enduring use as a high-fidelity audio amplifier. The atomic clocks first used
in the 1960’s by the U.S. military to track Sputnik and later to validate Albert Einstein’s relativity
theories are now the basis of Global Positioning System. And of course, the magnetron, invented in
the 1920’s at General Electric and used in radars during World War II, later found itself repurposed as
the basis for the microwave oven.
According to the text, complete the sentence: “The microwave oven…”
