Magic Mirror
★Exhibit Content: Popular science on visual illusions and the principles of cognitive biases of the brain ★Interaction: Manual interaction ★Operation: 1. Observe the shape of the opening above the model; 2. Rotate the turntable to a certain angle, observe and compare the actual shape of the model with its shape in the mirror. ★Function Overview: The exhibit consists of a plane mirror, a specially designed model set, a rotatable turntable, etc. It is a recommended exhibit for the KexMall exhibit mall. Rotate the turntable and compare the physical model with its image in the mirror; you will find that the image and the physical object have different shapes. Think about why this is? ★Scientific Principle: Why does the actual opening shape of the model differ from its shape in the mirror when observed from certain angles? The image of an object is transmitted to the brain through the eyes and processed by the brain, allowing us to understand it. However, when processing shapes, our brain tends to interpret objects as familiar shapes, discarding some extra details or filling in missing ones. In the exhibit, the edge of the model's opening is neither a simple straight line nor an arc, but concave on one side and convex on the other, like a lying S shape. When observed from the concave side, the opposite convex curve looks more like an arc, and the brain interprets this strange geometric body as a familiar cylinder. At this time, the object in the mirror is equivalent to being observed from the convex side, and the opposite concave curve looks more like a straight line, so the brain interprets it as a familiar rectangular prism. Observing things from different angles often yields different information. The ancient poem 'From the side, a range; from the front, a peak' describes exactly this principle.
