I expect most people have heard of the conic sections, the circle, ellipse, parabola and hyperbola which can all be formed by slicing a cone with a plane. I've just learned of this geometric method which can be used to find the two foci which are a separate way of defining or constructing an ellipse.
It turns out that if you take two spheres, such that they are tangent to the surface of the cone on a circle, and also tangent to the plane slicing through the cube at one point, those points where each sphere is tangent to the plane will coincide with the foci necessary to construct the same ellipse by finding the curve that is the sum of the distance from any point on the curve to the two foci.
In this image I've taken an overhead perspective view showing the surface area of the ellipse and the two small green spheres I've used to mark its foci or the points at which the spheres embedded in the cone were tangent to its surface.
You know, I think I would really like to study geometry more deeply, best yet as the mathematics of computer graphics. But I would want to study it à la carte, just choose whichever topics seem interesting and fruitful to me, without having to do things in the order someone else decided was best. No prerequisites either. Because if I have to know the math before I can use it then I will never use most of it, because I won't find most of it to be worth my time until I have an application to which it is an essential tool.
That's how I think math and physics should be taught, as the tools you need in order to construct your own video game.
SAN DIEGO (July 26, 2017) Quartermaster 2nd Class Amanda Franks describes equipment functions of the bridge to students during a STEM (science, technology, engineering and mathematics) event aboard the Wasp-class amphibious assault ship USS Essex (LHD 2). This event was part of the annual National Naval Officers Association (NNOA) Professional Development and Training Symposium coordinated with the San Diego chapter NNOA. The Department of the Navy is actively engaged in efforts to improve STEM education in the Unites States in order to ensure that an educated workforce is ready to meet the Navy and Marine Corps manning needs.

More than 700 fourth and fifth graders from four school districts in San Joaquin County converged on the Stockton campus of University of the Pacific for the sixth annual Math Steeplechase. They were split into teams of five to six students each and each team had to solve six complex mathmatical problems with only 10 minutes per problem. The best scoring teams and schools received trophies. It wasn't all just math. Students also were taken on a scavenger hunt on campus and also played games with Pacific athletes.
He say's he use to be a teacher. He taught mathmatics and economics to high school students before he became homeless.
Now I am presently figuring that the average national cost of what is a gallon of gasoline here in the state of Ohio is going to be within the $ 3.60 cent cost range for what will be the following months of June of 2008 if not higher. Now my present estimate is that I believe you can travel just about 45 miles more or less on just what is one gallon of that gasoline. So then the distance of about 45 miles for when it is divided down by the average cost of what is $ 3.60 cents per gallon for gasoline breaks down into what is about just 0.08 cents per gallon of gas for every mile that is traveled in your automobile. Now lets say you wanted to drive from the state of Virginia on the east cost to all the way across to the state of California to the pacific ocean on the west coast. Well that is about 2,509 miles only just one way. So then eight cents per mile times what is 2,509 miles traveled is about the cost of $ 200.72 for just one way only. So you need about at least if not more then $ 401.44 just for the return trip back on gasoline back to Virginia not including any other expenses you would incur along the way. If you intend to go traveling and to exploure the United States. Plan accordingly and bring about five or six times this amount with you. This would be about $ 2000.00 to 3000.00 dollars alone if not more.

This is the Caravaggio painting 'The Decapitation(or Beheading) of St John the Baptist'
He has been accredited with being a user of the Camera Obscura. His paintings certainly do have a mathmatical correctness about them.
This is the only painting he signed , he signed his name using paint he uses to represent the bloody outflow from the ongoing severance of the head.
Its the third painting he did that associates with chopping heads off. Nice. A bit of a fetish going on there , perhaps!
Always strikes me that artists of any time seem to paint images of the past , fact or fiction , in the style of thier present day .
The story of the shot/ painting is that Herod wanted rid of St John , aka Henry VIII style and reason , and a situation was created where he could legitimately present St Johns head on a silver platter to some woman who on dancing well was allowed to choose a present for the accomplishment .
Not suprisingly ??!! she chose St Johns head ! it is what any fullsome dancing girl would go for if she could chose owt in the world from a powerful and rich King...
Herod was then duty bound by the promise to deliver , damnation ,what a waste of a perfectly decent Saint , ah well ,he must have thought , what will be will be !
Off with his head!
Religion eh ...good stuff !
:-)
PS I did not take this shot , I lifted off Wiki , I just wanted you to see it for completion of what is at the St John the baptist cathedral
