Consequently, results of scientific experiments are now appearing on YouTube and attracting a larger audience. Read this informative article by Jacob Berkowitz to find out more.
While gearing up for the holidays, I found this entertaining video with Engineering Professor Larry Silverberg (a.k.a.

The search commands, AND, OR, NOT, (also known as Boolean operators, named after its British mathematician inventor, George Boole) can be used to combine your words in many search engines and research databases. Here’s a short video that explains how to use AND, OR, NOT when searching:
