Advances in modern materials science and thermal engineering have enabled us to precisely shape and control the temperature field of an object's surface, creating localized thermal environments that transcend natural experience. This provides an ideal experimental platform for studying human thermal perception. By establishing a stable, directional temperature gradient on a single conductor, we can make different parts of the same object exhibit drastically different thermal states. When the human hand, a sophisticated biosensor, comes into contact with this, the "contradictory" information collected by its distributed network of temperature receptors conflicts with the temperature model in the brain based on everyday experience, thus sparking cognitive curiosity and exploration. The "Knowing Cold and Hot" exhibit is a clever application of this principle. In this 1200*650*1050mm device, a special metal tube, under the action of a hidden temperature control system, maintains a constan
Gravity is the downward pulling force that no object on Earth can escape. The core of electromagnetic levitation technology is to create a continuous, controllable upward force to precisely counteract gravity and achieve stable levitation. This is typically achieved through the interaction between an electromagnet and a controlled object (containing magnetic materials or conductors). The system needs to monitor the position of the levitated object in real time and quickly adjust the current of the electromagnet through a feedback loop, thereby generating a magnetic force equal in magnitude and opposite in direction to gravity, "locking" the object at a certain equilibrium point in the air. Essentially, this is a dynamic and precise force balance, an elegant victory of magnetism over gravity. Our "Magnetic Levitation Light Bulb" exhibit transforms a transparent device, 1.4 meters in diameter and 2.6 meters high, into the stage for this "anti-gravity magic." When you press the start but
The scale of astronomical measurements often surpasses human intuitive imagination. The average distance between the Earth and the Sun—approximately 150 million kilometers—is defined as an "astronomical unit," serving as our primary yardstick for measuring the solar system and beyond. However, the real challenge in understanding this number lies not only in its spatial distance but also in its temporal delay. Even at the speed of light (300,000 kilometers per second), it would take approximately 8 minutes and 20 seconds to travel from the Sun to Earth. This means that the Sun as we see it "at this moment" is actually what it looked like 8 minutes ago. The "Earth-Sun distance" is not merely a length but also a "depth of time" defined by the speed of light. Our interactive exhibit, "The Distance Between the Earth and the Sun" (3000*800*1200mm), aims to make this abstract astronomical scale tangible and understandable. Visitors can choose from historically significant measurement methods
When high-energy charged particles ejected from the sun reach Earth's magnetic field, are guided towards the poles, and collide with atoms in the upper atmosphere, one of Earth's most magnificent natural light shows—the aurora—is born. Different gaseous components (such as oxygen and nitrogen), when excited, release light of specific wavelengths. Oxygen atoms primarily produce green and red light, while nitrogen molecules contribute blue and violet light. Essentially, this is a giant "fluorescent" phenomenon occurring hundreds of kilometers above the Earth. Understanding the aurora is understanding the epic energy transformation between the particle stream from the sun, Earth's magnetic field, and the thin atmosphere. Our interactive "Aurora" exhibit brings this cosmic drama from the poles to your doorstep within a 1.5-meter-high vacuum-sealed acrylic tube. Using safe and controlled high-voltage discharge technology, we simulate the process of particles exciting gases inside the tube.
Mathematics, often considered the pinnacle of abstraction and rationality, possesses a stunning beauty of form and structure at its core. From the elegant undulations of a sine wave to the infinite details of a fractal, each exquisite formula corresponds to a unique spatial logic and visual pattern. However, traditional learning methods often stop at symbolic derivation, failing to intuitively perceive the aesthetic impact of its graphical representation. Liberating the beauty of mathematics from abstract symbols, making it a visible and tangible art, is key to bridging rational cognition and sensory appreciation. Our interactive exhibit, "The Beauty of Formulas," bridges this gap within a delicate 400*400*600mm space. Visitors first select a mathematical formula on a touchscreen, ranging from classic sine and cosine to the graceful rose curve. The system then uses multimedia animation to explain the formula's geometric meaning and generative logic. Next, the exhibit's core precision
Human temperature perception is not simply a thermometer reading, but a complex symphony orchestrated by nerve endings, signal transmission, and brain decoding. Our skin contains different receptors sensitive to cold and heat stimuli. When these receptors are activated simultaneously or sequentially, the signals undergo integration and interference during transmission to the central nervous system, sometimes even producing subjective perceptions that contradict the actual physical temperature, such as "hot/cold illusions." Understanding this phenomenon is the starting point for exploring the subtle gap between perception and reality. Our interactive exhibit, "Knowing Cold and Heat," uses a special metal tube (1200*650*1050mm) integrated with a precise temperature control system to translate this neuroscience principle into a direct sensory experiment. When you touch either end of the tube, you can clearly experience the preset sensations of cold and heat. However, when you try to touc
