- Toll Bridge (Old), Hudson, WI (johnweeks.com)
The Hudson Toll Bridge was built in 1913, and it closed in 1951 after a new US-12 bridge was built one-half mile downstream. Today, people refer to the bridge as the Old Toll Bridge. Toll income from the bridge resulted in City of Hudson residents paying little or no property taxes for many years.
- Amaterasu particle (Wikipedia)
The Amaterasu particle, named after the sun goddess in Japanese mythology, was an unexpected ultra-high-energy cosmic ray detected in 2021 and later identified in 2023, using the Telescope Array Project observatory in Utah, United States. It had an energy exceeding 240 exa-electronvolts (EeV) and was inferred through the two dozen particles it sent toward ground detectors. This single particle appears to have emerged, inexplicably, from the Local Void, an empty area of space bordering the Milky Way galaxy. The single subatomic particle held energy roughly equivalent to a brick dropping to the ground from waist height.
