I retired in 2006 and bought Mathematica and a stack of math books with the goal to teach myself to become a world-class mathematician. I am on pace to achieve that goal sometime shortly after the next Ice Age.

I consider myself a Mathematical Mutt (no papers) who occasionally ventures off the back porch to play in the yard with the big dogs.

I donate regularly to the The OEIS Foundation.

When I look at the patterns, I can hear the wheels turning. When I look at the math, I find out the hamsters have died.

comment Aren't there obvious patterns in the primes that no one makes use of and what about this...
It doesn't fit my page.

Chasing links in en.wikipedia.org/wiki/Back-of-the-envelope_calculation will give some insight.

comment Can Waring problem be solved with triangle inequality?
@GerryMyerson, My reasoning is that the fractional part designated in the original problem description is not continually increasing or decreasing which makes it hard to solve. But, taking the differences at each $k$ is always decreasing. So the fractional part of $\left(\frac{3}{2}\right)^k$ is just a piece of $1-$ difference and thus has less influence on the inequality. Also, by a separate inequality, we can show that $2$ (at $k=1$) is the only integer that can possibly occur.

comment Sublists Conjecture
@GregMartin, I figured that out after I wrote Wow, so I added the length to show how incredible that answer is. Incidentally, 401 is a prime, so it can't be broken down into month and year.

@bubba, Carpenters call it kerf and they must account for it to build things. Sawmills do the same to determine board-feet of a log. The volume of this kerf is the sawdust.

comment Can a simple plot be used as a proof-without-words?
Sorry, I switched accepted answers. I like both, but decided to go with the induction.
