Explainer Zone™ on Instagram: "In this moment, a simple bottle balanced on top of a moving vehicle captures something surprisingly real about human behaviour — we get used to objects and routines so quickly that we sometimes overlook the smallest details. A bottle like this can remain upright only when the surface is steady, speed is controlled, and movement is smooth, showing how stable the ride actually is. While it looks funny and careless, it also reveals how friction, weight distribution, a

Explainer Zone™ on Instagram: "This video shows a vintage pen plotter, a type of early computer-controlled drawing machine widely used from the 1970s to early 1990s for technical drafting, engineering diagrams, maps, and typography. Unlike modern printers that spray ink, a pen plotter physically moves an actual pen across the paper using precision motors and coordinate commands. These machines were known for producing extremely accurate straight lines and curves, which made them essential for ar

Artificial Intelligence (AI) on Instagram: "This tongue-controlled device is redefining accessibility. Placed on the roof of the mouth, it works like a wireless trackpad—letting paralyzed users navigate phones and computers with precision and complete independence. A breakthrough in human-tech interaction, built by MIT-trained engineer Tomás Vega. • Follow @artificialntellligence for more content on AI and technology. #innovation #accessibility #technology #future #design #engineering #assistive

Explaining The Universe on Instagram: "NASA’s space “claw hand” is a specialized robotic gripper designed to collect rocks and soil in environments with little to no gravity. It uses motorized joints and reinforced metal fingers or scoops that can close tightly around a sample without relying on weight to keep it in place. Cameras and sensors guide the arm so it can approach a rock accurately, then the claw secures it using precise, controlled pressure. Many versions also include drills or seale
