Blockchain Fundamentals: Bitcoin and Ethereum
Blockchain is a decentralized, distributed ledger system that records transactions in a secure, verifiable, and tamper-resistant manner. It operates without a central authority by relying on cryptography and consensus mechanisms to validate transactions across all nodes on the network. Bitcoin, the first major application of blockchain technology, was designed as a digital currency running on a public and permissionless blockchain. It uses Proof of Work,

Blockchain Technology Fundamentals
What is Bitcoin?
Bitcoin is the foundational concept that introduced the world to blockchain technology. It is fundamentally a decentralized, peer-to-peer electronic cash system designed to solve the Double-Spending Problem without relying on a trusted third party like a bank. The Bitcoin network operates on a public, immutable ledger (the Bitcoin Blockchain) which chronologically records every transaction. This ledger is secured by the Proof-of-Work (PoW) consensus

Understanding Reaction Time and Information Processing
Information Processing & Reaction Time Revision Sheet
1. Core Concept
The human brain processes information like a computer, in a series of stages from receiving a stimulus to producing a response. The speed of this processing can be measured by Reaction Time (RT).
2. The Information-Processing Model
A three-stage model explaining how sensory input is transformed into motor output.
Input: Information from the environment received via the senses.
Stimulus Identification Stage: Deciding if a stimulus
