Marble AND Gate definition

According to wikipedia: 'Walther Bothe, inventor of the coincidence circuit, got part of the 1954 Nobel Prize in physics, for the first modern electronic AND gate in 1924'

Well, lets try to trivialize his incredible contribution to the scientific achievement of mankind by trying to repeat his feat with dollar store marbles, popsicle sticks, and glue.

 Lets start by defining a marble AND gate. We begin by defining a large marble to be a true, and a small marble to be a false. Then a marble and gate will take in 2 inputs and produce 1 output. We can produce a table of inputs and outputs as:

i1 i2 output
o o   o
o O  o
O o  o
O O O

Any marble machine that corresponds to the above table is an AND gate!

Marble Computer Language

In symbols one observes an advantage in discovery which is greatest when they express the exact nature of a thing briefly and, as it were, picture it; then indeed the labor of thought is wonderfully diminished.   - Liebniz To build an AND gate, we need some smaller components. We also need a language to talk about the smaller components. 1. Consider a marble run component with one input track and two output tracks. If a big marble is put into the input track, it comes out on the left output track. If a small marble is put into the input track, it comes out on the left hand track. We call this component a Separator. We use the following symbol, an inverted Y with a double hash to denote which side the big marble comes out:  | // \ 2. Consider a marble run component with one input track and one output track. The marble going into the input track comes out of the output track but is delayed. We call this component a Delay with the symbol: Z 3. Consider a marble run co

Marble Separator Prototype

He is ready to separate the chaff from the wheat with his winnowing fork. - Mathew 3:12 I like to define the ones as wheat and the zeros as chaff. I need to build a winnowing fork to separate the marbles for operations like sorting. I have a couple of landscaping pitchforks in the garage with tines the perfect distance to separate 'shooters' from 'cats-eyes', but they are way too big to go into a computer and I need them to spread wood chips. Recall that we defined a separator as a component that takes in a marble and routes it one direction if it is a large marble (wheat) and routes it another direction if it is a small marble (chaff). Here is a youtube video of my first separator made with popsicle sticks and glue: Eureka! I've done it! This is the first of my components to build my marble computer!! And it's pretty small, only about 3x2x6 = 36 cubic inches. With only 8 components in an AND gate, an average gate might be 288 in^3. Then a full adde

Initial Musings

I want to build a computer out of marbles. I told a few people about this plan and they look at me like I am crazy. What do I mean by making a computer out of marbles? Modern digital computers take in instructions called 'programs' and execute them by running electricity through specialized gates. The results are then usually either returned or stored. Instead of running electricity through electronic gates, I intend to run marbles through mechanical gates using gravity to the same end (albeit slower and smaller). The 'DigiComp II' and the 'Rule 110' marble computers are already built, but I will be doing something a bit different than those and other marble computers I've seen. My computer will use 2 different sized marbles for 1's and 0's and not store all information in the marbles themselves rather than the state of the machine.
