Material objects have half-lives.

We know how old things are because carbon-14 loses half its mass every 5,730 years. Measuring this radioisotope lets anthropologists and geologists date fossils and specimens up to 50,000 years old.

Ideas have half lives too.

The Old Testament was written over 2,000 years ago and is still being discussed today. There were many texts written that time as well, but most have been forgotten.

On this blog, there are posts from years ago that still get traffic, and others that barely get read at all.

How an idea is presented is important. If we hope to change the world, we should plan to find a medium and message where the impact lasts more than a few seconds.

Anything less, and it will be forgotten in no time.
