Citizen Science Musings: The Future of Citizen Science?
Recently it was my pleasure to have a long, informative chat with a couple of gentlemen who are part of an emerging trend outside the more settled model of “citizen science.” Continue reading…
The “Long Sought”, Practical Prime Number Formula Has Been Known (But Not Recognized as Such) Since Ancient Times
The search for a simple and easy to use formula, that would produce integers guaranteed to be prime, has gone on since ancient times. It appears that no one ever happened to notice (until I did) that a type of equation which has been known since ancient times, will produce integers that are guaranteed to be prime, if the equation is set up properly.
