I ran into the word “无常” a few days ago, and it really intrigued me to find out its meaning. “无常” or “世事无常,” in my understanding, means that everything in the world is constantly flowing, so change is the natural state of things. Interestingly, it reminds me of the Heisenberg Uncertainty Principle in quantum mechanics.
What happened so far in 2026? So far this year, I have continued trading NVIDIA options, generating approximately 11% return (~37% annualized on a non-compounding basis). From late February to early April, I developed a strong trading cadence — in capital allocation (options vs. stocks), timing of entries and exits, and strike price selection to
I picked up The Art of War again this week — a quiet return to something that helps me feel grounded, especially after being pulled into other people’s energy lately. “胜军先胜而后求战, 败军先战而后求胜.”A winning side secures victory before entering the battle.A losing side fights first, then tries to win. Over the past three weeks, I thought
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
It has been a while since I shared my Nvidia options trading updates. As many of you know, the U.S. stock market in 2025 has been extremely volatile — sharp highs and lows, rapid reversals, and plenty of uncertainty. For option traders, volatility can be both an opportunity and a source of stress. Premiums get
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
