科学家赫谢耳1800年在红光区域外侧发现了红外线后,人们根据对称思维就猜测在紫光区域外也可能有一种看不见的射线。后来,科学家里特在1801年果然在实验中发现了这种射线,即紫外线。在基本粒子的研究中,人们根据对称性,由已经发现的粒子猜测可能有反粒子(质量相同而电荷相反的粒子)存在,后来被实验完全证实反粒子的存在,是一个很重要的发现。它说明物质世界中存在着一种很基本的对称性,就是正粒子和反粒子的对称性。当然,我们可以通过联想与类比,使思维继续深化:有反粒子,有没有反原子呢?这一猜想也为现代科学实验所证实。现已发现了一些由反中子、反质子组成的反原子核(带负电),它同阳电子组成反原子。有反原子就可以猜想有反分子,也可以有……麦克斯韦方程揭示了电
When Hesscher discovered infrared rays outside the red light region in 1800, people speculated that there may be an invisible radiation outside the violet region based on symmetry. Later, in 1831, scientist Ritter discovered in the experiment that the rays, namely ultraviolet rays. In the study of elementary particles, based on symmetry, people guessed from the discovered particles that there may be anti-particles (particles of the same mass but opposite charges), and it was later confirmed experimentally that the existence of anti-particles is a very important discovery. It shows that there is a very basic symmetry in the material world, which is the symmetry between positive particles and antiparticles. Of course, we can continue to deepen our thinking through association and analogy: antiparticles, anti-atoms, and this conjecture is also confirmed by modern scientific experiments. Some antinuclear (negatively charged) nuclei consisting of anti-neutrons and antiprotons have been discovered. They form anti-atoms with cation electrons. There are anti-atoms to guess there are anti-molecules, there can also be ... Maxwell’s equation reveals electricity
