It’s amazing how something can make total sense while being hard to wrap your brain around it at the same time!

It is a sad day indeed to share the news of William (Jack) Welch’s passing. I won’t duplicate here his achievements and awards, list his papers, nor attempt to wax poetic about his outsized contributions to the fields of radio astronomy and SETI. That’s all here and here.

What I’d like to add is that he was a wonderful person. As you can see from the picture below, he always had a smile, kindness, warmth, fun, and positive energy to share. He had the soul of an explorer, realistic yet indefatigable.

We’ll miss you, Jack.
