Live Demo: Dot Product Visualizer, a mathematical toy

This was developed as an aid to understanding the dot product function used in Fractal Kitty's There is(Ǝ) – Such that (∋) project.

The dot product is the length of vector A projected on vector B (you can imagine this as the length of the shadow that A would cast on B, if a flashlight were shining perpendicularly at B), times the length of vector B. If the two vectors point in directions 90° apart, the dot product is 0 since neither has a component in the other's direction. If they point in the same exact direction, it is just the full length of A times the full length of B.

Mathematically, the dot product of vectors A and B defined as |A| * |B| * Cos θ, where |A| and |B| are the lengths of vectors A and B, and θ is…

Online Fact-Checking Tool: The Internet Bad Statements (“BS”) Detector

Here's a fairly old repost from my consulting site, where it got no traction whatsoever.

The Bad Statements Detector is a specialized search tool designed to aid in online research and to help prevent people from passing along nonsense on the internet, by making it easier to look stuff up on fact-checking websites like Snopes.com, Politifact, FactCheck.org, and other myth-busting websites all at once.

It works very simply: drag a “Detect BS” button to your bookmarks bar to create a "bookmarklet", a javascript bookmark that opens a tool when clicked. Then, while you surf the web, you can drag your mouse to select text on any web page and click your “Detect BS” bookmark link. This will return no-nonsense links from a multitude of reputable fact-checking and science websites that tell you if the statement you selected is well-known BS (plus offer you some sharing options right from the popup.)
