The history of polka dots
Polka dots have a curious history that dates back to medieval Europe when spotted patterns were associated with disease, making them widely feared. However, with the advent of the sewing machine during the Industrial Revolution, fabric production improved, allowing for the precise, evenly spaced dots we recognize today. The name "polka dot" emerged in the mid-19th century, likely inspired by the polka dance craze, though the exact connection remains unclear.
The pattern gained mainstream appeal in the 20th century, notably when Miss America 1926, Norma Smallwood, wore a polka dot swimsuit. It became further entrenched in pop culture through Disney’s Minnie Mouse in 1928 and the 1960 song Itsy Bitsy Teenie Weenie Yellow Polka Dot Bikini.

Washing clothes in space!
Unlike on Earth, there are no washing machines or dryers on the International Space Station (ISS). Water is a precious resource in space, and traditional laundry methods are impractical. Instead, astronauts wear their clothes much longer than they would on Earth—sometimes for several days or even weeks—until the garments become too dirty or smelly to continue using. Afterwards, the clothes are treated as waste and disposed of, often by loading them into cargo ships that burn up upon re-entry into Earth's atmosphere.
To address the issue of laundry in space, NASA and other space agencies have explored innovative solutions. For example, they’ve developed antimicrobial clothing to reduce odour and extend wear time. Additionally, researchers are experimenting with ways to clean clothes in space, such as using air or steam to remove dirt and bacteria. These efforts are crucial for long-term missions, like those to Mars, where resupplying clothing from Earth won’t be feasible. The article highlights how even mundane tasks like laundry require creative problem-solving in the unique environment of space.

Thought of the Week
“Most regrets, by the way, are acts of omission and not commission. If you do bad things, if you go murder somebody, that would be bad and that would be an act of commission that you would regret. But most everyday, ordinary non-murderers, when they’re 80 years old, their big regrets are omissions.” ~ Jeff Bezos
