Well I've just balanced a whole lot of dominoes up and what I wanted to do is look at how computers actually do maths for us. How on earth can a mechanical system like just a chip in a computer - how can it actually do arithmetic. This is my input Domino here. If I bump the input Domino it's going to send a signal down the chain and normally you ju... Read More

Questions & Answers

Q: How do domino circuits demonstrate logic gates like AND and EXCLUSIVE OR?

Domino circuits showcase logic gates by simulating inputs and outputs, showing how they operate in tandem to produce specific results like AND and EXCLUSIVE OR.

Q: What is the significance of using dominoes to explain binary arithmetic?

Dominoes simplify complex binary arithmetic concepts, making them visually understandable through physical demonstrations of logic gates and circuit behavior.
