It is only fitting that Albert Einstein should have begun his scientific endeavors as an experimentalist since theory and experimentation go together. Experimentation supports theory, and theory motivates experimental efforts. Basic research is experimental activity for the sole purpose of extending the knowledge base of our human experiences. Very little ,if any ,application or usefulness is intended. Most people do not understand the importance of such basic research, but without it, we undercut the knowledge base from which applications can arise.
Applied research comes forth from basic research efforts.
It is easier to look for direct application in any scientific efforts, and much funding for research implies the need to justify the investment in terms of tangible application. However, the efforts of basic research sometimes does not yield immediate tangible results or application. Sometimes, such application comes many years later. For example, the photoelectric effect found application in the electronic tubes that powered our first computers in the 1940's R. H.
