It's strange to think we walk around with powerful supercomputers in our pockets, yet we don't use them as much as we should to learn interesting facts about the world. Our planet is massive, always changing, and there's always something cool to learn. Just take a note from these people and learn something incredibly cool.


Reddit user, u/[deleted], wanted to hear about:

What's something cool you recently learned about?

It Comes Around So Rarely, It's All Chance

The origin of the word "happiness" is from the Middle English "hap" which has to do with chance and possibility. As in "happenstance" or per-haps. So hap-iness was originally about the feeling of good fortune/getting lucky; the chance that something could or could not occur, and then it goes your way. Happiness is that specific feeling when something that could have gone horribly wrong goes amazing well.

For the last 50+ years, every submarine and aircraft carrier built by the US Navy has been powered by nuclear reactors. What's more, the aircraft carriers have a 50 year service life and only need to be refueled ONE TIME. There has also never been a nuclear related accident on board these ships (two subs have sank, but not because of a failure in the propulsion system).

Monitoring All Aspects Of Prisoner Life

The shower water on Alcatraz was intentionally kept very hot.

This is so prisoners wouldn't get used to cold water and be able to swim to shore if they escaped.

Within Our Line Of Sight

On December 21, 2020 Jupiter and Saturn will align such that you can see them together in the same telescope, and even with the naked eye. It's called The Great Conjunction.

Edit: To answer some common questions:

  1. It should be viewable from most anywhere in the world. In the Northern Hemisphere look southwest. In the Southern Hemisphere look south.
  2. The best time to view will be 30 minutes to 2 hours after sunset.
  3. If it's cloudy on the 21st don't worry. The 21st is just the date that they're closest. But since the planets move so slowly across the sky it should allow for similar viewing in the several days before and after the 21st.
  4. The planets will appear pretty low in the sky so try to find a viewing location where you can see as much of the horizon as possible in the proper direction. Since there are several nights this will be visible it's best to try early to find the right spot.

A Protective Wall

No one who was born blind has ever gone on to develop schizophrenia. Researchers are investigating how congenital blindness may protect people from developing the condition.

The New "Normal"

Museums are struggling to keep the appropriate humidity levels for their collections because of the lack of foot traffic and people breathing in the buildings due to COVID.

Edit: should say I heard this on the podcast "No Such Thing as a Fish", which I highly recommend, as I'm sure many in this comment chain would as well :) I think, as some have pointed out, "struggle" might not be the right word to have used, but it does appear from the research I did this morning that it is something museums are dealing with due to lack of foot traffic creating a "new normal" of humidity in these places.

Y'all know that one Hannah Montana song? “Everybody makes mistakes! Everybody has those days!" That's the song I sing to myself every time I accidentally burn myself while making ramen. It comforts me to know, however, that there are a lot of worse mistakes out there than some spilled ramen. Who knew?

When I was younger, it seemed every adult believed that you couldn't swim for several hours after eating. Why did they all believe this? I fought them on this all the time, by the way. I shouldn't have had to, just because I'd eaten some barbecue during a pool party. Guess what, though? That belief is unfounded.

As much as we're not supposed to feel satisfaction upon observing the struggles of other people, it can be hard to resist a silent, internal fist pump when some blunder occurs immediately after we tried to help the person prevent it.

One of the most upsetting aspects of the Covid-19 pandemic––which is saying a lot, frankly––is the number of people who have been so affected by misinformation and disinformation. You know the ones to which I refer: These are the people who are convinced the virus is a hoax despite the lives it's claimed and the devastation it has wrought on society at large. Disinformation kills––there are stories of people who remained convinced that Covid-19 is a hoax even while intubated in the ICU, even up to their last breath.

After Redditor asked the online community, "Doctors of Reddit, what happened when you diagnosed a Covid-19 denier with Covid-19?" doctors and other medical professionals shared these rather unsettling stories.
