## Who Is This Euler And What Does He Want?

Leonhard Euler amazes and humbles me each time I run across something he discovered. Recently I ran across the equation Come On!! A series of integer square inverses adds up to Pi squared over 6?? How weird is that?

## Clean Lines

I am drawn to and dedicated to the clean crisp logical way mathematics and lots of science are constructed. For example, consider this kid's problem: what's the power sum of the first n positive odd integers? Answer: n-squared. Demo: take first 2 positive odd integers and sum...

## Euler's Identity

Since this is the ONLY entry so far I figured it was a good place to start. It is described as tying together five of the most important numbers in math: 0,1,e, i, and "pi" - the additive identity, the multiplicative identity [of groups], the basis for a function which is its...

## So I came across this in my random internet

adventure and really enjoyed it 😄## Help Required

Can anyone out there explain to me why a constructible universe L in set theory is defined by the axiom V = L where V is the von Neumann universe of cumulative hierarchy? If L is that class of sets that are definable, according to some parameters and quantifiers, why is L not...

## Simply The Best

Religious zealots often hawk theirs as "The Perfect" or "Best" religion, claiming all others are inferior. Can math shed some light on this? Let me try.... In topology, not a topic studied by most, there is Morse Function Theory which basically determines the highest point of an...

## Except When It's Dumb Shmuck Nonsense

A report out today that I saw in an Aussie online newspaper, led me to its source, the media & marketing department of the University of Tennessee at Knoxville. It headlines a study just published in the extremely distinguished Proceedings of the National Academy of Sciences of...

## Quaternions

These extensions of imaginary numbers form a Vector Space over R4, were discovered [invented?] by Hamilton, a giant of mathematics. They do NOT follow the commutivity rule of ordinary multiplication. For example, (8 x 3) = (3 x 8) = 24 as we all know. But quaternions are non...

## Lagrange Points

Joseph Lagrange, a mathematical giant who might be called nine feet tall if it were stature, defined these 5 points centuries ago when celestial mechanics was first formulated. In the ideal case of a planet orbiting circularly around the sun there will be five such points, so...

## I Can't Learn Enough Science

My first two degrees were in Math and Computer Engineering. Then I got one in Electrical Engineering. Now, I am in a Biophysics program, and I assist in teaching Chemistry. As Dr. Wheeler once wrote: "As our island of knowledge grows, so does our shore of ignorance."
