Glenn Engel is inviting you to a scheduled Zoom meeting.
Topic: Bob Cutler - what research after retirement looks like
Time: Feb 4, 2026 01:00 PM Pacific Time (US and Canada)
We all remember Bob Cutler as the math and signal processing whiz keeping HP at the forefront of the digital communications boom. After retirement he has kept his math chops active looking at the signals buried in celestial mechanics and it's relationship to our climate. He has reached some interesting conclusions about this and after a bit of prodding has put together a presentation/summary of his findings and is inviting you to hear about it:
It took 15 minutes to accidentally discover how to predict global temperature from sunspot data, and another year to figure out why it worked. Now, after two more years of research I’ve finally discovered the smoking gun: climate at a given location repeats with striking precision after 3,560 years. Please join me as I highlight this repetition in climate records from around the globe, and then explain how this clockwork 3560-year precision originates in the orbits of the Sun and Jovian planets. It’ll be fun, and I promise everyone will learn something new.
I hope you can all find time in your busy retirement schedules to make the zoom meeting. Call in early and chat with old friends - maybe trade emails. Feel free to forward to our other exlks friends whose exlks email is no longer valid. Is it time for another exlks reunion? Maybe a discussion topic!
As a teaser, here is a graphic showing how shifting temperature reconstruction by 3560 years confirms a repeating pattern:
