Discovering the physics behind 300-year-old firefighting methods
From American Institute of Physics 26/01/24 Today, water pressure technology is ubiquitous, and any person who showers, waters a garden, or fights fires is benefiting from the technology devised to harness it. In the 17th and 18th centuries, though, a steady stream of water not punctuated by pressure drops was a major breakthrough. In 1666, […]
Pingpong balls score big as sound absorbers
From American Institute of Physics 25/10/23 Long-term exposure to low-frequency noise can cause numerous health problems, but the solution may be found in an unexpected object, a pingpong ball. Conventionally thought of as the hollow plastic balls that speed through the air during a fast-tempo game of table tennis, with a few modifications, pingpong balls […]
