Many parents around me want their children to pursue the Olympiad programming path, but they are often troubled by questions like: “Is it suitable for a first grader to learn programming?” “Can we skip Scratch and go straight to C++?” “How should GESP and CSP-J be connected?” As a practitioner deeply involved in Olympiad education … Read more
Triangle, a geometric shape composed of three sides and three angles, may seem simple, but it is rich in meaning andcharm is infinite. It has wide applications in various fields such as mathematics, art, architecture, and nature. First of all, the triangle is one of the most basic geometric shapes, and its stability is its … Read more
Step by step, one can reach a thousand miles.【Daily Practice】The goal is to provide various problems for practice and explanation as a reference to help everyone improve. Friends can use the explanations as a reference or leave comments to share their methods.///////////////////////////////////////////////////////Today, I want to tell everyone that programming is not limited by tools; as … Read more
When it comes to programming, many people fall into the “either-or” fallacy: thinking that Scratch is for “children” while C++ is for “serious programming.” However, few notice that these two seemingly disparate tools actually share the same “soul”—algorithmic logic.Today, we will break down a key question: Are Scratch and C++ “of the same origin” or … Read more
There exists a very clear and inevitable progressive connection between learning Scratch, Python, and C++. These three are not isolated from each other, but rather form a classic learning path from “programming thinking enlightenment” to “practical application development” and finally to “system-level deep control”. We can understand this inevitable connection from the following core aspects: … Read more
Introduction to Digital Tubes A digital tube is a type of semiconductor light-emitting device, with its basic unit being a light-emitting diode. Digital tubes are categorized into seven-segment and eight-segment types, with the eight-segment tube having an additional light-emitting diode unit (for displaying a decimal point). The connection method for light-emitting diode units is divided … Read more
Today we will introduce the “Lissajous Figures.” The so-called Lissajous Figures are closed curves formed by the superposition of two mutually perpendicular simple harmonic motions. Background Knowledge: What is “simple harmonic motion”? It is somewhat similar to the swinging of a swing, the oscillation of a clock pendulum, or the “Biu” sound of a spring … Read more
This topic is a bit heavy, and I dare to throw out a brick to attract jade. Currently, maker education and programming education are being promoted across the country. I visited some schools and communicated with several teachers. Maker education is generally at a preliminary stage. I had an in-depth discussion with Teacher Chen from … Read more
