Exhibits and Principles of China Science and Technology Museum

The exhibits and principles of China Science and Technology Museum are as follows:

1, China Science and Technology Museum, as one of the largest science and technology museums in China, has a variety of exhibits covering science, technology, engineering, mathematics and other fields.

2. Stellar instrument: Stellar instrument is an instrument used to observe the position of stars in the night sky. Through a series of rotating shafts and dials, it enables the observer to accurately measure the direction and angle of the star, thus determining the position of the star. This helps astronomers to study constellations, galaxies and other celestial bodies in the universe.

3. Kaleidoscope: Kaleidoscope is an optical instrument, which consists of colored glass fragments and mirrors. Light passes through stained glass and reflects on the mirror, which will produce beautiful symmetrical patterns. This shows the principle of refraction and reflection of light, and the dispersion effect, so that white light can be decomposed into different chromatograms.

4. Electromagnetic induction: China Science and Technology Museum usually shows the principle of electromagnetic induction. Through the interaction between magnetic field and conductor, electromagnetic induction can produce current. The audience can see that when the copper coil moves in the magnetic field, it will generate current, thus lighting the bulb. This demonstrates the basic principles of electromagnetic induction and power generation.

5. Balancing robot: Balancing robot is usually a robot with sensors and control system. It can keep balance and won't fall when moving. This shows the principle of control engineering and feedback system, and the robot keeps balance by constantly detecting its own posture and environment.

6. Laser interferometer: Laser interferometer is a precision measuring instrument used to measure the interference effect of light. It uses laser beam and beam splitter to observe the interference fringes when beams interfere with each other. This can be used to measure length, detect vibration and study the properties of light.

Matters needing attention in exhibits of China Science and Technology Museum

1. Reservation and queuing: During peak hours, the China Science and Technology Museum may have a long waiting time in line. If possible, book tickets online in advance to reduce waiting time. You can also choose to avoid peak hours, such as weekends or holidays.

2. Safety regulations: Please observe the safety regulations and instructions of China Science and Technology Museum, including prohibiting touching the exhibits and maintaining order. This helps to ensure the safety of you and other viewers.

3. No photography and video recording area: Some exhibition areas may prohibit photography and video recording, because this may cause interference to exhibits or other audiences. Please observe these regulations.
