There is a film crew in the office here filming us so I decided to put an Easter egg equation on the wall to see who watching it will catch the reference.

Person: If I start at 0 and count up in infinitesimal increments to the number one how many numbers must I count?

Wiseman: infinite

Person: and if i start at 0 and count up in infinitesimal increments an infinite number of times what number will I arrive at?

Wiseman: all of them

You know you are a nerd when you by a textbook for over a hundred dollars and at twice the price just to get it new and then cant sleep the night before because your excited to get it....

Found this in my notes from a while back. Shows how to calculate the values for a balun to match a transmission line to an antenna.

Sometimes when im bored ill just doodle out little math proofs to make sure i remember the solutions. I admit, i am a nerd.

Excuse the poor handwriting, I was just scribbling and not really trying to write nice.

@math

When you hear the word "graph" what do you think of?

I hope everyone had a fantastic Pi day. Its always a bit sad when the holiday season is over though. I will miss the pi day carolers and all the pi day treats and lawn decorations.. cant wait till next year!

@math
That time a mathematical proof to an unsolved math problem was just casually posted anonymously to 4chan... Mathematicians found it some time later and realized, remarkably, a long outstanding problem in maths had finally been solved...

100 Pots Puzzle

About a year and a half ago I presented the 100-pots puzzle, which is by far my favorite programming/logic/math problem I have ever come across. It took me a while to solve it the first time I heard it (most of the work day which is where I heard it). I also was at an advantage because the solution comes from a field of math I have particular expertise in, so most people will probably have a harder time solving it.

I don’t think anyone was able to solve it last time I presented it, and had to give the official answer, I could be wrong, I need to dig up the thread. @Absinthe however did write a simulation for it in python after I had posted the answer.

Anyway here is the problem for anyone who wants to take a stab.

All answers or hints must be CW’ed

No tricks

First off some background. The problem is not a trick question, as much as it may seem like one. There is no play on words, no hidden exception. Everything in this problem is exactly how it is presented and the answer doesn’t rely on any slight of hand. Take this puzzle at face value.

The Puzzle

There is a room with 100 jars with lids on them all in a row. There is also a stack of papers, 100 papers each labeled 1 to 100. The papers are shuffled and one paper placed into each pot randomly.

You and your assistant are in an a joining room. Your assistant is allowed to enter the room, look in all 100 pots, and if they wish they can pick any 2 pots and switch the paper in them. They can only do this one time, they do not have to do this they can choose to also do nothing. At this point they leave the room, without talking to you.

Next, someone tells you a random number from 1 to 100. Your goal is to enter the room and open a pot that has that number in it. You are allowed to open, at most, 50 of the pots.

Whatever process you use to open those pots must guarantee that by the time you open the 50th pot that the number you were given will be found. Obviously your assistant didn’t know what the number is at any point.

What rules do you give your assistant, and what rules do you follow, to ensure you are successful?

I am way too excited by this novel little discovery of continuous complex fibonacci sequence.. I need to play with this!

I really do love heat map visualizations of data, there is a certain beauty to it when seeing patterns emerge.
