Topic: How we get a Ellipse from a Conic, and how we get a Oval from
Cylinder Sections-- knifes that are V and asymmetrical V shaped

4) Harvard's Mark Kisin, Peter Kronheimer, Jacob Lurie as dumb as
Mike Moroney, still teaching a ellipse is a conic when even students know it
is a OVAL

3)Stanford's Tom Church, Ralph Cohen, Brian Conrad, as dumb as Jan Bielawski, still teaching a ellipse is Conic when in truth it is Oval

Jan Bielawski says that take a section of Cone and it is a ellipse, and, take a section of cylinder and it is an ellipse, for which, even the idiot Franz responded that seems counterintuitive, but which Franz still believes is true. Anyone not crazy as Jan or Franz, knows the cone is different from cylinder and would immediately recognize the oval is the conic section, but not crazies.

Now the Rectangular Solid, a box, has a sectioning, a cut that is a rectangle, and the rectangle is the analog of an ellipse, and the Rectangular Solid is the analog of a Cylinder

Now, the Square Pyramid is the analog of a cone, and the sectioning of the square-pyramid, if you listen to the crazies around here-- Jan Bielawski, Franz, Jan Burse, Mike Moroney, Alouatta, etc, if you listen to the crazies, well, they would chime in and say the sectioning of the square-pyramid is a rectangle, when in fact, it is a trapezoid.

So, since Stanford University math professors keep teaching that the Ellipse is a Conic section, we can only say, that the Math Department at Stanford is as dumb, as crazy as is Jan Bielawski.

And that is a horrible statement of fact, that math professors at Stanford keep teaching young students a pitiful and crazy math. When students deserve far better.

Now, I have a toy collection of Geometry figures one of a rectangular solid (box), cone, square-pyramid and cylinder. All four are see-through plastic.

Please, some Stanford students take those see through plastics to classes at Stanford and ask the professor what sections does he/she get from each.

Students deserve better, than to have a bunch of crazies teaching them.
