QUESTION: Dear Prof Scott

en.wikipedia.org/wiki/Postage_stamp

Other than Rectangle, Square, Diamond, Kite shapes can we construct postage stamps with other possible shapes viz Circular, Oval, Trapezoid, Pyramid, Triangle etc ?.

Thanks & Regards,

Prashant S Akerkar

ANSWER: The rectangular is the easiest to construct. Other shapes would cost more due to the waste involved in material that couldn't be used.

See, if we take a piece of paper, and cut horizontal and circular lines that are equally spaced apart, smaller rectangles are easily generated. We could also generate trapezoids are triangles with a small amount of waster, but there would still be some. Other shapes would generate even more waste material.

QUESTION: Dear Prof Scott

Thanks.

Can we construct cone,cylinder, rhombus,parabola, ellipse,hyperbola shaped postage stamps?.

Thanks & Regards,

Prashant S Akerkar

Well, they need to be two dimensional in order to stick to a surface.

They could be formed as just part of the outside of a cylinder,

but when torn off they'd be close enough to flat to work.

Again, they need to be formed into a flat shape since that is two dimensional and easily sticks to a letter. Even if letters were made to have some three dimensional aspect to them,

that would make it a lot more difficult to send them through in such massive amounts.

They are two dimensional so it is easy to put them in stacks of 100's or 1000's.

Adding another dimension would make storage be a whole lot more.

Now if we were advanced enough to make stamps allow letters to fly to a destination, perhaps they could be formed in the shape of an airplane ...

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later.
I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman.
I tutored at Mathnasium for well over a year.
I worked at The Boeing Company for over 5 years.
I received an MS degreee in Mathematics from Oregon State Univeristy.
The classes I took were over 100 hours of upper division credits in mathematical courses such as
calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more.
I graduated with honors in both my BS and MS degrees.
Past/Present Clients: College Students at Oregon State University, various math people since college,
over 7,500 people on the PC from the US and rest the world.
**Publications**

My master's paper was published in the OSU journal.
The subject of it was Numerical Analysis used in shock waves and rarefaction fans.
It dealt with discontinuities that arose over time.
They were solved using the Leap Frog method.
That method was used and improvements of it were shown.
The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.
**Education/Credentials**

Master of Science at OSU with high honors in mathematics.
Bachelor of Science at OSU with high honors in mathematical sciences.
This degree involved mathematics, statistics, and computer science.
I also took sophmore level physics and chemistry while I was attending college.
On the side I took raquetball, but that's still not relevant.
**Awards and Honors**

I earned high honors in both my BS degree and MS degree from Oregon State.
I was in near the top in most of my classes. In several classes in mathematics, I was first.
In a class of over 100 students, I was always one of the first ones to complete the test.
I graduated with well over 50 credits in upper division mathematics.
**Past/Present Clients**

My clients have been students at OSU, people who live nearby, friends with math questions,
and several people every day on the PC. I would guess that you are probably going to be one more.
