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"

Dr. Joyce Kahng | Cosmetic Dentist OC Veneers on Instagram: "All about Black Triangles on Lower Teeth (Part 1). I still have a 1:30 limit on Instagram so had to split this one up. Part 2 will go over management and collaboration with the Hygienist. Raise your hand if you hate black triangles!"
