IAE Blog

Information Age Education (IAE) is an Oregon not-for-profit corporation founded by David Moursund in August 2007. The IAE Blog was started in August 2010.

The Math Learning Center

I was one of the founders of the Math Learning Center (MLC) and have served on its Board of Directors since this 501(c)(3) organization started 40 years ago. During these 40 years, I have advocated for increased use of calculators and computers in math education. Several hundred of my math education and computer education publications are available free online (IAE, 2017). Three of my more widely read math education articles are (Moursund, 2017a; Moursund, 2017b; and Moursund, 2017c).

One of my contributions to the MLC was getting it started in developing some online Math Manipulatives programs (Moursund, 4/19/2013). A catalog of the MLC’s current collection of 11 free online math manipulatives is available (MLC, 2017).

The purpose of this IAE Blog entry is to call your attention to some of today’s robots. I was amazed by some of the materials I read recently.

The talk and the videos all focus on robots being developed by Boston Dynamics, a company founded in 1992 by Marc Raibert, a MIT graduate. He is still the President of the company, although the company is currently owned by Japan's SoftBank Group. Japan is particularly concerned about providing personal health care for its aging population, and is exploring the use of robots as one possible approach to meeting this growing need.

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.):

Free Weekly Newsletter from MIT

The purpose of this IAE Blog entry is to introduce you to The Download, a free newsletter from the Massachusetts Institute of Technology that I enjoy reading (MIT, n.d.). One of the interesting aspects of this free newsletter is that you can specify the areas you like to keep up with, and the weekly newsletter you receive will then focus on the topics you specify. The list of topic areas is:

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.
