上这个周一端午假期的最后一天，和小宝贝的同学家长一起约好了。带两个小宝贝去参观省科技馆，当天也发了帖子。今天详细说说参观的感受。其实武汉已经有一个科技馆了，就在江汉关边上，是之前的武汉客运港改造的那个地方，位于城市中心交通还是蛮方便的啊。这个省科技馆坐落于光谷新区，开车都得一个小时左右。而且我们去襄阳的时候，襄阳也有一座建筑非常现代化的科技馆，感觉多少有些重复建设了。当然，我们说市场经济是欢迎竞争的。不过，科技馆作为公共事业部门，并不是市场化运营的，这些场馆都无意例外采取预约制免费参观。他们也不是依据利润考核来决定运营的成功与否。所以这些科技馆之间并非竞争的关系，他们也没有讨好观众的压力。就拿武汉市科技馆来说，里面的展品不可谓不丰富，也不可谓不新颖。拿去和我参观过的香港科技馆对比，可以说完全是碾压式的。不过这么多年了，感觉里面的展品从开馆之后也没怎么更新过。
而这个省科技馆是近年来才开的新馆，里面的设施就更新了，分上中下三层，三层是主要展区里面的展品还是偏科普。总体来说，感觉并不算丰富，也没有什么让人眼前一亮的，大都是对基本科学常识的简易实验展示，可以让孩子对这些常识有一个感性的认识，但是能提起他们多大的兴趣，则很难说。除了那个演示时空扭曲的相对论效应的投影仪之外，很少有能抓住小朋友眼球的设备，很多设备只有对基础物理有所了解的情况下，才能看出点门道。而如果大人在旁边讲解呢，可能情况要好一点，但是这次是和小伙伴一起去的。小宝贝是没有兴趣听你大人在那里啰嗦一堆他们还不太理解的科学知识的。
比如其中有一台设备是用来展示光的干涉的，打开按钮，就可以在白色背景板上看到两个对比的光斑，一个是激光通过单缝时候的，可以看出它是一条连续的红色带状光斑。另一个就是激光经过双缝之后形成的明暗相间的斑点条纹。这个对比图案虽然看似简单，但是如果深入下去，通过光的干涉几乎可以推导出深奥晦涩的量子力学中的所有基本知识的，其实是一个看上去平常，细思极恐的实验。你只要想想，光实际上是由一个一个的光子发出来的。这些斑点实际上是很多个小光子密密麻麻排列出来的，你就会感到不可思议。当单个的光子穿过狭缝的时候，它是怎么知道？旁边是否还存在另一个狭缝的呢？
当然，正当我想深入给小宝贝讲一讲的时候，她却已经跑开了。不过这个设备还是影响我的兴趣。说实话，这也是我第一次亲眼看到这一实验现象。以前就是在学校里上课的时候，印象中老师似乎并没有做过这个实验的演示。于是拼多多上搜了一下，真是感叹现在的网络购物啊！类似的效果几乎一样的实验设备在拼多多上，只要十五块钱一个。好吧，等小宝贝再大一点可以在家里跟他做这个实验了。
单看这些展馆中的展品似乎并没有特别的太特别的地方。不过既然是新馆的新，也必然有它的体现。这个省科技馆的新意之处就在于它的影院部分。它的影院部分有高清巨幕和沉浸式观影两部分，其中沉浸式观影，就是在场馆中心大厅的黑洞模型顶部有一个类似天眼射电望远镜形状的碟形。而这实际上是一个电影屏幕，而它的观影方式也非常特别。在这个碟形屏幕的周围有一个栏杆走道，观众就站在栏杆上面，凭栏观看影片。效果非常类似于各种游乐场所中流行的球幕沉浸式电影。
而当天播放的影片内容是《星盾计划》大概八分钟。短片有一个故事情节，说是有一颗磁星，也就是快速旋转，带有非常强大磁场的中子星闯入了太阳系，它的磁场会给地球带来严重的破坏。于是人类齐心协力将小行星改造成超导防护网布置在地球的周围，躲过了这场危机。其实严格来说，这个故事的设定是比较扯的，磁星一般都是中子星，而中子星是比太阳还要巨大的恒星死亡后留下的残骸。如果真有这样一个星球闯入太阳系，那么他带来的真正的危险可不是磁暴那么简单，比太阳还要强大的引力场会完全扰乱太阳系内八大行星的轨道，地球面临的不是被推到离太阳更远的寒冷边疆，就是被推入太阳的火海当中毁灭掉了。而影片的3都特效也比较一般。不说是五毛钱吧，最多也就是一块。但是巨幕影院的效果非常棒。放的影片是捕捉昆虫的植物。需要带3d眼镜观看。效果和阿凡达差不多。当然就是时长太短。
Last Monday, the last day of the Dragon Boat holiday, and the parents of the little baby's classmates made an appointment together. Take two little babies to visit the provincial science and Technology museum, the same day also posted. Today I will tell you more about the visit. In fact, Wuhan already has a science and technology museum, on the edge of Jianghan Pass, is the former Wuhan Passenger Port transformation of the place, located in the city center traffic is quite convenient ah. This provincial science and technology museum is located in the Optics Valley New District, which takes about an hour to drive. And when we went to Xiangyang, there was also a very modern science and technology museum in Xiangyang, which felt a bit repetitive. Of course, we say that a market economy is open to competition. However, the science and Technology Museum, as a public sector, is not market-based operation, and these venues have no intention of making an exception to the reservation system for free visits. Nor do they determine the success of their operations based on profit assessments. So these museums are not in competition with each other, nor are they under any pressure to please the audience. Take Wuhan Science and Technology Museum for example, the exhibits inside are not not rich, nor can be said to be not novel. Compared with the Hong Kong Science and Technology Museum I have visited, it can be said that it is completely crushed. However, after so many years, it seems that the exhibits inside have not been updated since the opening of the museum.
The provincial science and technology museum is a new museum opened in recent years, and the facilities inside have been updated, divided into upper, middle and lower three floors, and the three floors are the exhibits in the main exhibition area or partial science popularization. In general, the feeling is not rich, there is nothing to make people bright, mostly simple experimental demonstration of basic scientific knowledge, can let children have a perceptual understanding of these common sense, but can raise their interest, it is difficult to say. With the exception of a projector that demonstrates the relativistic effects of warping time and space, there are few devices that can catch a child's eye, and many that can only be seen if they have some understanding of basic physics. If an adult is there to explain, it may be better, but this time it is with a friend. Babies are not interested in listening to you grown-ups spout a bunch of science they don't quite understand yet.
For example, one of the devices is used to show the interference of light, open the button, you can see two contrasting light spots on the white background board, one is when the laser passes through a single slit, you can see that it is a continuous red ribbon spot. The other is the light and dark spots formed after the laser passes through the double slit. This contrast pattern may seem simple, but if you go deeper, through the interference of light can deduce almost all the basic knowledge of the esoteric quantum mechanics, in fact, it is a seemingly ordinary, extremely thoughtful experiment. You just have to think that light is actually emitted by photons one by one. These spots are actually a lot of tiny photons packed together, and you can't believe it. How does it know when a single photon has passed through the slit? Is there another slit next to it?
Of course, just when I wanted to talk more about the baby, she had run away. But this device still affects my interest. To be honest, this is also the first time I have seen this experimental phenomenon with my own eyes. In the past, when I was in school, the teacher did not seem to have done the demonstration of this experiment. So spell a lot of search, really lamented the current online shopping ah! Similar effects are almost the same experimental equipment in pinduoduo, as long as 15 dollars a piece. Okay, you can do this at home with baby when he's a little older.
Looking at the exhibits in these pavilions alone, there doesn't seem to be anything special about them. However, since it is the new museum, it must also have its embodiment. The novelty of this provincial science museum lies in its cinema section. Its cinema section has two parts: high-definition giant screen and immersive viewing, which is the black hole model at the center of the hall with a dish resembling the shape of the Visualize radio telescope on top. And this is actually a movie screen, and the way it's viewed is very special. Around this dish-shaped screen is a walkway with a railing on which viewers stand and lean to watch the film. The effect is very similar to the ball-screen immersive movies popular in various amusement venues. The movie that aired that day was "Project Star Shield," about eight minutes. The short film has a storyline about a magnetar, a rapidly rotating neutron star with a very powerful magnetic field, that has broken into the solar system, and its magnetic field will cause serious damage to Earth. So mankind worked together to transform the asteroid into a superconducting protective net arranged around the Earth, avoiding the crisis. In fact, strictly speaking, the setting of this story is rather ridiculous, magnetars are usually neutron stars, and neutron stars are the dead remnants of stars larger than the Sun. If such a planet really breaks into the solar system, then the real danger he brings is not so simple as a magnetic storm, a gravitational field more powerful than the sun will completely disrupt the orbit of the eight planets in the solar system, and the Earth will be pushed to the cold frontier farther away from the sun, or be pushed into the Sun's sea of fire and destruction. And the film's three special effects are relatively average. Not 50 cents, but a dollar at most. But the effect of the giant screen theater is fantastic. The film shows plants that catch insects. 3d glasses are required. The effect is similar to Avatar. Too short, of course.
