Someone once in the UK told me that it was a big enough problem that so many people turn on their electric kettles during the endtitles of Eastenders, that there's an employee in a hydro plant that needs to watch it to ramp up the power at the right time. I've finally found a wikipedia page about it.
«These tricks show Feynman taking the method of thought he learned in pure science and applying it to the more mundane topics most of us have to deal with every day.»
«This post is a condensed version of what I've sent to people who have contacted me over the years, outlining what everyone needs to learn in order to really understand physics.»
The Kessler syndrome (also called the Kessler effect,[1][2] collisional cascading, or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions.[3] One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.[3]

Psychology's reproducibility problem
It turns out there's more to cat litter than you think. It can soak up urine, but it's just as good at absorbing radioactive material.

Rita Levi-Montalcini OMRI OMCA (US: /ˌleɪvi ˌmoʊntɑːlˈtʃiːni, ˌlɛv-, ˌliːvi ˌmɒntəlˈ-/, Italian: [ˈriːta ˈlɛːvi montalˈtʃiːni]; 22 April 1909 – 30 December 2012) was an Italian Nobel laureate, honored for her work in neurobiology. She was awarded the 1986 Nobel Prize in Physiology or Medicine jointly with colleague Stanley Cohen for the discovery of nerve growth factor (NGF). From 2001 until her death, she also served in the Italian Senate as a Senator for Life. This honor was given due to her significant scientific contributions. On 22 April 2009, she became the first Nobel laureate ever to reach the age of 100, and the event was feted with a party at Rome's City Hall. At the time of her death, she was the oldest living Nobel laureate.
Margherita Hack Knight Grand Cross OMRI (Italian: [marɡeˈriːta ˈ(h)ak]; 12 June 1922 – 29 June 2013) was an Italian astrophysicist and scientific disseminator. The asteroid 8558 Hack, discovered in 1995, was named in her honour.
Samantha Cristoforetti (Italian pronunciation: [saˈmanta kristofoˈretti]; born 26 April 1977, in Milan) is an Italian European Space Agency astronaut, former Italian Air Force pilot and engineer. She holds the record for the longest uninterrupted spaceflight by a European astronaut (199 days, 16 hours), and until June 2017 held the record for the longest single space flight by a woman until this was broken by Peggy Whitson and later by Christina Koch. She is also the first Italian woman in space. Samantha Cristoforetti is also known as the first person who brewed an espresso in space.
