Light and darkness

The seasonal Christmas lights remind me of Thomas Edison.

After experimenting with thousands of filaments, he discovered a material that would glow well and last a long time for an electric light bulb. His effort literally lit up the world.

Was he a genius? Certainly. But more importantly, he did a lot of work.

I wonder how many dark moments he endured along the way.

*Note: Contrary to common misconception, Edison did not invent the light bulb. He built on inventions done by many scientists before him. However, Edison did advance light bulb design and contributed to the commercial success of electric lighting.
