Every physical process, from the motion of planets to the rise of consciousness, is the output of computational rules acting on data (bits). > 🗣️ > “If we reduce all the complexity of the universe to its first principles, what remains are the simplest distinctions — **1 and 0**, **something and nothing**. With those, we may describe all phenomena.” --- ## 💡 Core Idea: Leibniz’s Vision of a Calculable World Leibniz believed that **reason and calculation** could be used to resolve all disputes, understand all natural laws, and build systems of truth. He dreamt of a **computational metaphysics**（计算形而上学） long before computers existed. ### 🔄 Binary vs Decimal Systems | 十进制 (Decimal) | 二进制 (Binary) | | ------------------- | ---------------------- | | Base-10 system | Base-2 system | | Digits: 0–9 | Digits: 0 and 1 only | | Intuitive (fingers) | Efficient for machines | | E.g., 5 = 5 | E.g., 5 = 101 | > In Leibniz’s words: > “The simplest form of numbering — **0 and 1** — reflects the duality of being and non-being, and through them all things may be encoded.” --- ## 🧪 Key Components of the Computational Universe ### 1. **Bit-Based Reality** All matter and energy reduce to information, and the universe can be represented in **bits (0s and 1s)**. ### 2. **Laws as Code** The laws of nature are like algorithms — **mathematical rules** that process initial data to yield physical phenomena. ### 3. **Physical Systems = Computation** Physical entities are like **hardware**, and natural laws are **software**. Atoms = logic gates. ### 4. **Consciousness & Life** In this view, **life and mind** are emergent properties of high-level computations. Even human thought can be simulated in theory. > 🧠 Note to self: > If everything is calculable, what happens to mystery? Where do intuition and emotion go?
