YouTube Videos on Numerical Methods Cross 1-Million Views Mark

In a short 2.5 years since starting the numericalmethodsguy YouTube channel in January 2009, this month the channel crossed the benchmark of receiving 1 million video views.  Currently the channel gets between 2,500-3,500 video views per day.  Although we have playlists on the channel, the playlist for all the available topics are given on single webpage at http://nm.mathforcollege.com/videos/index.html

Complete resources on each topic of available numerical methods including textbook chapters, videos, multiple-choice tests, PPTs, and worksheets are  given at http://nm.mathforcollege.com/topics/textbook_index.html

A Wolfram demo on how much of a floating ball is under water

Here is another Wolfram demo. This one shows how much of a floating ball would be submerged under water.  The demonstration uses the specific gravity and radius of the ball as inputs.  Using calculus and Archimedes’ principle, the level to which the ball is submerged turns out to be the solution of a cubic equation.  To play with the demo, download the free CDF player from Wolfram first.
