Jahir Ali Khan on Instagram: "Ever wondered why bridges use triangles and why pillars are cylindrical? This simple experiment shows how geometry controls strength, stability, and load distribution in engineering structures. Triangles provide maximum rigidity, while cylinders evenly distribute stress — that’s why engineers trust these shapes in real-world designs, from buildings to machines. Science isn’t just theory; it’s visible everywhere around us. #engineering #science #physics #triangle"

MEMEZAR • MEMES & MEME-CULTURE on Instagram: "This temporarily broke my brain 😭 Optical illusions trick the brain by presenting visual information in a way that conflicts with how the brain normally interprets reality. They exploit the brain’s shortcuts for processing shapes, colors, light, and depth, causing it to see things that aren’t actually there or perceive them differently from reality. For example, lines of the same length may appear unequal, or a still image may seem to move because t
