Google Squared is an odd little Google experiment that the company just released, probably to try to counter the even odder Wolfram Alpha search tool.
Each tool is different from each other, and each tool tries to apply analysis to search requests, as opposed to the "old fashioned" search that just dumps a list of unfiltered results in your lap.
Wolfram Alpha comes from the company that developed Mathematica, an extremely powerful piece of software used by mathematicians, scientists, and math teachers and students. Alpha tries to provide quantitative analysis to search requests. This works quite well if you enter things like math formulas or chemistry formulas. But if you enter something like "Blacksburg Virginia" it decides you must be interested in two places: Blacksburg, Virginia and Virginia, Minnesota, and computes the distance and straight line flight time between the two places. Huh?
Google Squared tries to take search requests and turn them into a tabular format. This seems to work quite well if you are shopping for something, but many other search terms I tried seemed to confuse it.
