About Sunny Side Up Software

Sunny Side Up Software is a name that may require some explanation.

From 2018 to 2026, the main Sunny Side Up Software site hosted freeware Windows 10 and 11 applications that I created as a hobby. My interests shifted over time, and although I still maintain a few of the applications for personal use, I no longer offer the original applications online.

But back to the name. When I was looking for a name for the site in 2018, it somehow immediately occurred to me that I like my eggs sunny side up. And I was publishing software, so, voilà: Sunny Side Up Software.

Today, this science site serves as a simple gateway to three related sites, each using a subdomain of sunnysideupsoftware.com:

• GPS Relativity shows live GPS and GLONASS satellites and calculates how special and general relativity affect the selected satellite’s clock.
• Voyager Relativity follows Voyager 1 and Voyager 2 through deep space and shows how motion and gravity make time pass differently aboard them than on Earth.
• Quantum@Home uses small detectors in an ordinary home to make quantum effects visible through live data and short experiments.

Sunny Side Up Software is not a legal entity.
