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

Detailed Explanation on Instagram: "A Prince Rupert’s Drop is a teardrop-shaped piece of glass formed by dripping molten glass into cold water, which rapidly hardens the outside while the inside cools more slowly. This process traps intense internal stresses that give the drop its bizarre properties: the thick, rounded head becomes incredibly tough. Able to survive hammer blows, while the long, thin tail remains extremely delicate. If the tail is cracked or even lightly chipped, the entire drop
