There are many professionals who make a career of science communication. I'm sure they would do a better job than I at describing the ins and outs of how to effectively communicate science to the public. Instead of paraphrasing their ideas, today I am focusing on why I personally value science communication and public outreach.
Last night, I replaced the broken screen on my daughter's phone. This was my first attempt at electronics repair and involved taking the entire phone apart (phones have lots of little pieces!) and putting it back together again.
I started the project with fear that my meddling in the unknown would result in failure; I ended with satisfaction in a job well-done. It's funny how the emotional ups-and-downs of scientific research can be replicated in such a comparatively small project.
