Light likes to travel in straight lines, but when it moves from one material to another, it can bend or reflect depending on the angle. Engineers use this behaviour to trap light inside a very thin strand of glass. Even though glass feels fragile, these strands are made extremely pure and flexible, allowing light to move through them with very little loss. Because light is the fastest thing in the universe, using it to se

Explaining The Universe on Instagram: "In machining, lubrication—often provided through cutting fluids or coolants—plays a vital role in controlling heat, friction, and tool wear during cutting operations. As the tool shears material, it generates significant heat, which can cause the tool to dull quickly or the workpiece to distort. Lubricants create a thin film between the tool and the chip, reducing friction and preventing material from welding onto the cutting edge. Coolants help carry heat
