SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "Finding the true center of a wooden log might look like guesswork, but it’s actually a precise geometric method used by carpenters, woodturners, and sawmill operators. This video shows a reliable technique that works even when the log isn’t perfectly round. The process starts by identifying two random points on the edge of the log. From each point, straight lines are drawn across the surface toward the opposite side. When these lines intersec

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "Leveling tiles might look simple, but it requires precision, planning, and the right tools. This video demonstrates the professional approach to achieve a perfectly flat and even tiled surface: 1️⃣ Surface Preparation: The first step is ensuring the base is clean, flat, and free of debris. Any unevenness can cause tiles to crack or shift later. ⚡ 2️⃣ Mortar Application: A uniform layer of mortar is spread with a notched trowel. Proper thickne

SCIENCE | HISTORY | FACTS | EXPERIMENT on Instagram: "Sometimes, perfection isn’t lost in the beginning—it’s lost at the very end. This moment shows how a single final touch can completely change the outcome of a painting that was otherwise flawless. Art relies on balance: color harmony, contrast, spacing, and restraint.
