The Problem with CosmoLearning.org

If you found the site helpful, please consider sending a polite e-mail to the folks at CosmoLearning.org.   They have archived many of videos at the MathDoctorBob Youtube channel without permission.  While linking to videos is not a problem,  embedding videos decreases ad revenue and reduces incentive to create free product. We've asked once for their removal and they have failed to comply (as of 12/10/2017). 

Note that we have no affiliation or have ever affiliated with CosmoLearning.org

No need for donations.  While we do plan to produce more videos in the future,  time is a bigger factor than money at this point.  So unless you have a time machine, we're good.  

Of course, please pay it forward - suggestions include supporting your local animal shelter (we're actively involved in trap, neuter, and release for urban stray cats), the ACLU,  or other worthy charities or causes.
