Underwater Robotic Miners

Almost every day I find one or more science and technology articles that really catch my attention. David Hambling’s article about developing robots to do underwater mining certainly provides a good example (Hambling, 10/23/2017).

The problem that many mining operations face is that of water getting into a mine. The history of steam engines is intimately connected with this problem. Steam engines were first developed to pump water out of mines. Quoting from Encyclopedia.com (n.d.):

Larry Cuban

Larry Cuban is Professor Emeritus of Education at Stanford University. He was a high school social studies teacher (14 years), district superintendent (7 years), and university professor (20 years).

Over the years, I have read many of Cuban’s articles. While I have not always agreed with what he was saying, I am always impressed by the quality of his thinking and clarity in expressing his ideas.

In Terms of Vacuum Tube Dollars, Likely You Are a Billionaire

Most days I spend quite a bit of time browsing educational and technical websites. Today, this led me to reading about the early history of transistor radios and transistors.

The transistor was invented in 1947. In many electronic circuits such as in a radio, a transistor could be used in place of a vacuum tube (Wikipedia, n.d.a). The transistor is smaller, much more rugged, has a much longer expected life, and uses much less electric power.
