QUESTION: Dear Prof Scott

Can we Construct Concentric Stars?.

Thanks

ANSWER: All the stars in a galaxy are concentric in that they all rotate about the same center
(the center of the galaxy).

QUESTION: Dear Prof Scott

Thanks.

Can we have Concentric Star polygon?.

Thanks

Answer
Do you mean a set of stars that all rotate around the center of all of them?  Yes, it is possible.  However, there is not a star system anywhere that has uniform size stars with equal space between them.

There might be a triangle of stars somewhere that are almost all the same size, and maybe another triangle of stars that are of roughly the same distance apart, but it would be hard to just three stars with both.  In theory it would work, but in nature, it never does.

Just take a look at the trees.  If we tried and find two trees that looked exactly alike, we couldn't do it, for they all grow branches in differing spots.  Perhaps another one would be to find two people that looked the same.  It is very close to impossible.  Of course, twins could be looked at, but there is usually some little thing between them that is different.

Back to the stars - if a set was found that were roughly the same size and somehow put out by themselves in a cluster with a spin, perhaps it might be possible, but that is not a natural occurrence.

Even is something close was found, the differences in them would soon make them not be so equally distanced.

Expertise

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

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.
