This wasn’t a routine release. For three decades, water levels, structural safety checks, and changing environmental policies kept these massive spillways completely sealed. Today, for the first time in a generation, the gates were raised in a caref

Invention on Instagram: "Shredding an image into smaller pieces is a simple and effective way to understand the idea behind downsampling. When an image is physically cut apart and each small section is viewed on its own, the fine details disappear while the broader shapes and colors remain. This mirrors what happens digitally when an image is reduced in resolution. The computer keeps the essential structure but removes the smaller patterns that the human eye is less likely to notice at a smaller

ANALEMMA on Instagram: "The operating principle of a liquid hydrogen rocket engine can be divided into several key stages: 1. Storage and supply of fuel and oxidizer: A liquid hydrogen rocket engine uses liquid hydrogen (LH2) as fuel and liquid oxygen (LOX) as an oxidizer. These substances are stored in two separate cryogenic tanks at very low temperatures (hydrogen about -253°C, oxygen about -183°C). Fuel and oxidizer are supplied to the fuel lines using high-pressure pumps. 2. Mixing and feedi
