US Military Uses 8-Inch Floppy Disks To Coordinate Nuclear Force Operations
"The US Military still uses 8 inch floppy disks on outdated IBM computers to run the nuclear missile systems. It's because they are incredibly hard to hack. The computers are essentially air-gapped and the old IBM computers are reliable. They could run for another 40 years with spare parts." Start hoarding Floppy Discs. I have one.

Why Are Indian Battery Companies Reluctant To Take Up Li-ion Battery Manufacturing?
While battery companies in India have accepted the shift to EVs, they still remain cautious about moving in too early. Unless there is better demand visibility, it is unlikely that battery manufacturers would risk significant capital on the sector. "Investors appear to have two major concerns that led to the decline in the stocks – the risk of technological obsolescence and a slowdown in the automotive sector."

MIT has predicted that society will collapse in 2040
MIT had simulated many possible futures in the early computers of the mid 20th Century that led to various possible outcomes. Some of which led to the destruction of humanity altogether and some to a smaller collapse. Nevertheless, all simulations showed a major reduction in growth in around 2040, which has only accelerated as climate change wasn't taken into account in those simulations but is a major factor now.

The Big Misconception About Electricity
Derek says that if there is a light-second long wire that connects an AC battery to a lamp, then due to Maxwell's equation the energy flows from the battery to the lamp directly and not through the electrons. This is why the lamp will light up as soon as (or after 1/c^2 sec) the circuit is closed.
Great comment section.

Why heaters are the future of cooling - Vox
Heat pumps are more efficient than Air Conditioning units (ACs) and there is a growing demand for personal home cooling mechanisms, so a policy change that promotes heat pumps over ACs will greatly help in reducing global warming.
 
What If The Ocean Wasn't Salty?
The salt dissolved in the ocean is in the form of ions. These ions are usually in equilibrium and regulate the currents, temperatures of the ocean and the glaciers. However, in the recent years, due to climate change, the concentration of salt ions in the ocean is decreasing. If it continues at this rate, then the ocean currents will be affected resulting into warmer waters near the equator which will promote more violent and more frequent cyclones.
 
Some of Earth's Water Was Created by the Sun? | SciShow News
It was previously hypothesized by scientists that Earth's water came from comets and asteroids containing iced water that crashed into the Earth in it's early developmental stage. Though, recent measurements on the composition of water on the asteroids and comets have shown that they contain very less heavy water (deuterium instead of hydrogen in water). Therefore, now it is speculated that some portion of he water came from the Sun which has high amounts of Deuterium to form heavy water. Basically, during solar storms, the Sun shoots out a stream of ions. These are mainly hydrogen and deuterium ions that then collide with the atmospheric oxygen and get converted into water and heavy water respectively.

The curios tale of the man who slapped Tojo
TL;DR: Shumei Okawa was speculated to be the organiser of some attack called the Mukden incident. During the wait for his trial, he was seated just behind General Tojo (President of Japan during World War 2). This is when he slapped Tojo's bald head twice. Tojo simply smiled and was amused. "They had to put him out of slapping distance." Later on, Okawa was said to be mad which made him mentally not fit for trial and thus saved him from prosecution. He was sent to a psychiatric unit and then an asylum where he spent the rest of his life.
Here's a video that shows the incident:
