Due to experimental errors, the discovery of conductive polymers increased the number of catalysts by 1000 times. From 65438 to 0967, Korean students in tokyo institute of technology Hideki Shirakawa Laboratory accidentally synthesized a metal polyacetylene film with silver tape. This polymer used to be a white powder. By analyzing the experimental process, Hideki Shirakawa found that the polyacetylene sample was highly crystallized, forming a fibrous structure, because the experimenter interpreted millimoles in the experimental scheme as moles, and the Ziegler-Natta catalyst used was 1000 times of the common dosage.

After doping a small amount of bromine, the conductivity of polyacetylene increased by 654.38+billion times, which was close to that of silver. Subsequently, they cooperated with physicist Aranda Jaeger to study the doping mechanism. Miracle jellyfish and green fluorescein (GFP? No one has told a classic story like GFP. In fact, many scientific papers are talking about this historical process. Here is a brief talk about repairing villages.

In Japan from 65438 to 0956, the young Shimomura Xiu (pictured above) finally analyzed the structure of fluorescein, the source of scarab fluorescence. But what he didn't know was that his leader forgot to talk about this topic, and many people failed to come back. The success of fluorescein inspired Shimomura's fighting spirit and studied another incredible biological crystal jellyfish. According to Fresnel theory, if an opaque circular plate is placed on the propagation path of light.

Because light diffracts at the edge of the circular plate, there should be bright spots in the shadow center of the circular plate at a certain distance. Fresnel and arago, who were not surprised at that time, accepted this challenge and soon predicted this theory in their experiments. In fact, Einstein discovered the unified relationship of space, time and matter in 1905 and 19 15, and created them respectively. Special relativity? And then what? General relativity? . This is also a mistake.
