物质科学长时期以来处于科学的前列,20世纪前半叶起更极大地改变了人类的生活和人际关系。在这一时期中出现了运输、通信和各种大生产技术的革命,并开始了计算机和核能的利用。到20世纪后半叶,生物科学却走到了最前面,现在有充分根据预计21世纪将是生物科学的时代。这实际是物质科学发展的成果,因为如果没有以物质科学发展为基础的电子显微镜、核素、化学分析 Physical science has been at the forefront of science for a long time and has greatly changed human life and human relations ever since the first half of the 20th century. During this period there was a revolution in transport, communications and various mass-production technologies and the use of computers and nuclear energy began. By the second half of the twentieth century, biological science came to the forefront and is now fully justified as the 21st century is expected to be an era of biological sciences. This is actually the result of the development of material science, because if there is no electron microscope, nuclide, chemical analysis based on material science development
