What were the benefits of Albert Einstein's work?

Answer 1

Albert Einstein tremendously increased our scientific understanding of the universe in which we live. In terms of technological applications, his work created the theoretical basis for the invention of the laser, which is a highly vital item of technology, and he helped us to use atomic and nuclear power (both for peaceful purposes and for bombs); GPS technology would not be possible without correcting for relativistic time dilation effects, MRI scanners require an understanding of relativistic effects, and so forth. Einstein was tremendously important in bringing about the high tech society in which we now live.
