Scientific and technological knowledge

Society is used to linking science and technology together, collectively known as science and technology. In fact, there are both close ties and important differences between them. Science solves theoretical problems and technology solves practical problems.

The problem to be solved by science is to discover the relationship between facts and phenomena in nature and establish a theory linking facts and phenomena; The task of technology is to apply scientific achievements to practical problems.

Science mainly deals with unknown fields, and its progress, especially major breakthroughs, is unpredictable; Technology works in a relatively mature field and can make more accurate planning.
