Today we celebrate the contributions inventors have made to the world. Every February 11 since 1983 has been National Inventors’ Day in the United States, as proclaimed by President Ronald Reagan. It’s just coincidentally Thomas Edison’s birthday, too! He’d be 172 today. So hug your favorite inventor today. (Or, I mean, if you’re an inventor, you should totally use that automatic hugging machine you built for yourself!)
