Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. The project was started in 2013 by Dave Hakkens and is now in its fourth iteration. It relies on a series of machines and tools which grind, melt, and inject recycled plastic, allowing for the creation of new products out of ...
Bridgeville, California (population 25) was the first town to be sold on eBay in 2002, and has been up for sale three times since. [1] In January 2003, Thatch Cay, the last privately held and undeveloped U.S. Virgin Island, was listed for auction by Idealight International. The minimum bid was US$3 million and the sale closed January 16, 2003. [2]

Source tagging is the application of EAS security tags at the source, the supplier or manufacturer, instead of at the retail side of the chain. [6] For the retailer, source tagging eliminates the labor expense needed to apply the EAS tags themselves, and reduces the time between receipt of merchandise and when the merchandise is ready for sale.
As of 2023, a superconducting nanowire single-photon detector is the fastest single-photon detector (SPD) for photon counting. [8] [9] [10] It is a key enabling technology for quantum optics and optical quantum technologies. SNSPDs are available with very high detection efficiency, very low dark count rate and very low timing jitter, compared ...
Cryogenic particle detectors operate at very low temperature, typically only a few degrees above absolute zero. These sensors interact with an energetic elementary particle (such as a photon ) and deliver a signal that can be related to the type of particle and the nature of the interaction.

In physics, particle detectors are used in the experimental study of radioactivity, nuclear physics and particle physics; they are also important as a surveillance tool in nuclear safety. Particle detectors may range from the simplest, such as photographic film and Geiger counters , to the most complex used in particle colliders .
