While reading A Brief History of Time, I came across several concepts that sparked my curiosity — one of the most intriguing being the Twin Paradox. I wanted to summarize what it is and why it matters, in a simple way. The paradox compares how two twins experience time differently when placed under two separate
In the past few weeks, I’ve been learning the basics of CPU, GPU, quantum mechanics—and today I wanted to understand: How does my phone connect to the internet? I always had a few questions in my mind: Here is the simple version of what’s actually happening. 1. Why my phone starts to have internet when
When I first learned about GPUs, I assumed they were basically the same as CPUs — after all, both provide computing power and both are everywhere in high-tech discussions.But once I started learning about electrons, transistors, and how chips actually work, I became curious:Is a GPU really the same as a CPU? The answer is
In the past three weeks, I’ve been exploring the foundations of quantum mechanics and how they relate to computing. I learned that in traditional computers, information is processed using binary language (0 and 1), while quantum computers use qubits that can represent 0, 1, or both at the same time through a principle called superposition.
Nowadays, we often hear about quantum computing. So what is it, and why do we need it? Here is my simple understanding: Quantum computing builds on a key idea from quantum physics: electrons behave both like particles (mass) and waves. Instead of fighting this nature, quantum computing uses it. Traditional computers use bits — 0
Last week, I explored the basic structure of the atom.Today, I want to take one step further — to connect those tiny particles called electrons with something that powers nearly every part of modern life: the semiconductor industry. Electrons behave both like particles and waves — a concept known as wave-particle duality. Each electron carries
As I began reading A Brief History of Time, I realized I needed a stronger foundation in atomic structure. This summary captures what I’ve learned—both as a record of my understanding and a quick reference for my future review. 1. The Basic Composition of Matter Atom → The smallest unit that retains the properties of
