Experiments in Thinking

Your brain remembers experiences, recognizes patterns, and knows countless things it was never explicitly taught. How does it manage all that? These interactive Labs let you explore a radically different approach to AI. BrainSim Thought uses connected Atomic Thoughts to represent knowledge, retrieve information, and remember sequences.

Create knowledge, change it, and watch the results appear in a live 3D graph. Each Lab contains several short, hands-on experiments. Follow the suggested challenges or explore on your own. You’re interacting with the actual BrainSim Thought software—not a scripted demonstration.

These interactive Labs demonstrate ideas from AI With Understanding: How Atomic Thoughts Model Thinking and Could Transform AI by Charles Simon (coming February 2027). Explore the software yourself, then dig into the book to see how—and why—it works.

The Atomic Thought

Chapter 2,  5 experiments

Lab 1: How can your brain represent facts?

Start with Fido, add facts about him, and watch a network of Atomic Thoughts take shape. Discover why a Relationship is itself a Thought—and how Relationships can describe other Relationships.
Then explore the network and create some knowledge of your own.

Inheritance with Exceptions

Chapter 5,  4 experiments

Lab 2: How can you know something you’ve never been told?

Give a dog a few attributes, then make it a member of a category. Watch it instantly inherit knowledge that was never stored with the individual.

Introduce exceptions, search for things using their attributes, and discover how recognition leads to predictions.

Sequences and Memory

Chapter 7,  4 experiments

Lab 3: How does your brain remember things in order?

Explore how Atomic Thoughts represent the letters in a word, recognize fragments of stored sequences, and remember patterns of colors and timing.

Then try the same machinery with music: remember a melody then recognize it from just a few notes and hear what comes next.

We’re expanding the experiments to explore learning, language, algorithms, and mental models. Check back as new labs will explore more capabilities of BrainSim Thought.

The Ideas Behind the Experiments

These Labs accompany AI With Understanding: How Atomic Thoughts Model Thinking and Could Transform AI, by Charles J. Simon, scheduled for publication February 1, 2027.

The book explains the architecture behind the experiments and explores how Atomic Thoughts might provide a foundation for human-like knowledge, learning, and reasoning.
