Elliptical Paraboloid and Southern California

Post by dbhguru » Wed Feb 20, 2019 4:27 pm

ENTS,

While rusticating here in sunny Southern California, I’ve been completing an Excel worksheet to compute the volume of an elliptical frustum that can be conoid, paraboloid, neiloid, or anything between. It seems to be working, but needs more testing. The worksheet as it exists now is attached.

I’ve also been getting reacquainted with Mount San Jacinto and San Gorgonio. They are HUGE! San Jacinto rises abruptly around 10,300 feet above a Palm Springs. A very imposing sight. John Muir felt the view from the summit was unsurpassed anywhere. Quite a testament. The following image is of 11,500-foot San Gorgonio. I’m on a hill above the place we’re staying. Elevation 1535 feet. Elevation at the house is 1,348 feet.

Behind San Gorgonio there are two very beautiful towns, Lake Arrowhead and Big Bear Lake. I visited them in 2012 and saw this beauty:
