The only scientific and technological symbol of Mianyang in the country - Science and Technology Museum. The core location of Youxian District, convenient transportation, magnificent appearance and rich interior. Three floors, the main lecture on Mianyang research related to nuclear energy, aerospace, two bullets and one star. The advantages are obvious: the venue design is reasonable, the layout is open, the focus is highlighted, and the content is deep, suitable for a certain knowledge reserve. Disadvantages: the equipment is old, repaired for many years, most of the interactive equipment is all scrapped, and the moving is the legacy products of the last century; Secondly, knowledge update is slow, many still stay ten years ago; once again, some exhibitions are too professional, in order to be lazy, large-scale excerpts of professional introductions, long-term accumulation, teenagers and the general public are difficult to understand. Overall, it is a good place to popularize knowledge, and some new experiences such as wind tunnels are also worth trying. Four-star recommendation, feel the deterrent of nuclear energy cities.
