Engineering | Science | Technology on Instagram: "After exactly 30 years, one of the world’s most iconic dams has opened its gates for the first time since 1995 — an event engineers, environmentalists, and locals have been waiting decades to witness. 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

How Everything Is Made on Instagram: "This battery-free kinetic sculpture works on stored mechanical energy. With just a single twist, a hidden spring winds up — and as it slowly unwinds, it releases that energy into a series of precision-cut Eucalyptus and Ash plywood blades. Each blade is angled and spaced to create a continuous wave-like motion, so the energy transfers smoothly down the mechanism for up to 15 minutes of movement. There’s no motor, no battery — just clever engineering, frictio

Jodie Kammerer • AMAZON HOME FINDS on Instagram: "✨ON SALE NOW!!✨I love the look and ease of these pullout basket drawers! They install in seconds and secure with heavy duty Nano film adhesive! This stuff is STRONG! Before I installed these pullout drawers this cabinet was a mess! It was jammed full of stuff and I hadn’t seen the back of my cabinets in years! Now, with just a little pull I can access all the storage potential of the cabinet! And I didn’t even have to get out my drill! Incredible

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

CREATE on Instagram: "Rocket engines work by taking stored chemical energy and converting it into directed momentum. Inside the vehicle, super-cold propellants-usually liquid oxygen (LOX) and either RP-1 kerosene or liquid hydrogen-are pushed through turbopumps that spin faster than 30,000-100,000 RPM. These pumps raise the propellant pressure high enough for it to enter the combustion chamber as extremely fast, atomized streams. Once the fuel and oxidizer meet, they burn almost instantly. This

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

Wealth on Instagram: "Some of the world’s most valuable crypto fortunes are locked inside tiny devices like this and recovering them is a science of its own 🔐💰 Digital forensics specialists are sometimes called in when a damaged flash drive contains an encrypted wallet. Their job is to extract the memory chip, stabilize it, and read its data using advanced hardware that can access each storage channel individually. It is one of the most delicate branches of data recovery because even a microsc
