“Knowledge is powerful and self-education is the only education there is.” — Isaac Asimov
We have all benefitted from the unprecedented advances in technology, planetary exploration, and medicine that have taken place during our lifetime. Between 1945 and 1971 there were many breakthroughs, and the progress has accelerated ever since.
For us seniors, it is a challenge to understand and keep up with the changes, and to a lesser extent, for our younger generation as well.
History can provide a thread of knowledge and excitement for the privilege and pride to be part of it. For that reason, I have researched a timeline of significant events for our readers (and myself!) to think about, share with the next generation, and explore deeper if so motivated.
