SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "This video shows a master craftsman sculpting a perfectly smooth curved ledge using a custom wooden trowel, and it’s a brilliant example of precision meeting traditional technique. Unlike flat plastering, curves demand constant control of pressure, angle, and motion. 🔹 Why a wooden trowel? Wood absorbs moisture slightly, preventing plaster from sticking and tearing, which helps achieve a smoother, more organic curve. 🔹 Controlled geometry:

E History on Instagram: "This street artist doesn’t touch the canvas directly — instead, he controls a marionette that paints for him. Every string pull becomes a brushstroke. Every movement turns into color, chaos, and control at the same time. What looks like a puppet show slowly reveals a finished painting, created through precision, patience, and performance. The audience isn’t just watching art being made — they’re watching art being performed. It blurs the line between artist and tool. Who

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "Industrial chains aren’t just metal links — they’re precision-engineered components designed to carry thousands of tons without failure. This video reveals how extreme strength is forged step by step: 1️⃣ Material Selection: High-grade alloy steel is chosen for its ability to handle massive loads, fatigue, and sudden shocks. Even tiny impurities can weaken the final chain. 2️⃣ Heating & Forging: Steel rods are heated to glowing temperatures a

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "Your smartphone battery looks simple from the outside, but inside it’s a carefully engineered chemical system powering your entire digital life. Most modern phones use lithium-ion batteries, and here’s what’s actually inside them: 🔹 Anode (Negative Side): Usually made of graphite. This is where lithium ions are stored when your phone is fully charged. 🔹 Cathode (Positive Side): Made from lithium metal oxides (like lithium cobalt oxide). Thi

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "This video shows how artificial intelligence and 3D printing are completely changing rocket engineering. Engineers now use AI algorithms to design rocket engines that humans could never calculate manually. 1️⃣ AI-Generated Design: Instead of traditional blueprints, AI analyzes airflow, combustion pressure, and heat distribution, then creates an optimized engine shape with internal channels impossible to machine by hand. 🤖 2️⃣ 3D Printing the
