What's some very informative but practically useless information you'd like to share?

Bass frequencies require more power than high frequencies to travel the same distance, although because of this bass frequencies will move through textures and high frequencies will reflect. That's why you can hear the subs from festivals kilometres away. Edit: Yes this is why bass frequencies shake your house. Also, I know this information is actually pretty useful come to think of it. Edit 2: yes, telling me that I hear bass frequencies because the high frequencies are absorbed in the air is correct. Edit 3: yes, lower frequencies have longer wavelengths and higher have smaller. It's all very useful information if you an audio guy, but if you have a small speaker setup at home it's useless.

When mark zuckerberg first started off he figured he wanted to paint the walls in his office but had no money to do it. So he found a painter and asked him if he can pay him in equity from his new start up (facebook). So the painter agreed and painted everything so mark gave him 1% stake in the company. Long story short, The painter is now a billionaire.

Most ancient Incas and many other ancient South American native tribes had the same blood type, (O Negative). The ancient Incas were masters of blood transfusions and had a high success rate due to most of the population having the same blood type.

If you pick the Shoshone in Civ V you get an initial border growth, pick tradition to lower the culture cost of border growth and the pantheon Religious Settlements to increase border growth by 15 percent. Then rush Angkor Wat which halves the culture and gold cost of border expansion. Relish in large swaths of land that you can barely use.

Gary Numan is just over a week older than Gary Oldman.

The second player controller controlled the duck on Nintendo's Duck Hunt.

Astronomer here! Here is a crazy one- it now appears that statistically all stars have planets. We have confirmed over 2,000 of them so far, but surveys via microlensing (which don't yield confirmed planets, but interesting other info) indicate there are likely around 100 billion extrasolar planets in our galaxy. There are about 100 billion stars in our galaxy, and interestingly the study that came up with this estimate suggested also that there would be more Earth sized planets than Jupiter ones (which is against the current grain of confirmed planets because bigger ones are easier to spot via current techniques). So, for comparison, if you take our local neighborhood of 50 light years radius from us, there ought to be at least 1,500 planets in it. :D

"When Nintendo wanted to get the NES onto shelves in the US, companies were very warry of video game consoles due to the market crash caused by Atari. So Nintendo threw together a robot toy named R.O.B to package with the NES, because robot toys from Japan were popular as hell. Essentially they said "Hey, you guys want to stock this cool robot toy? Well, you have to package it with this video game console." And the stores begrudgingly agreed, and people bought it, then quickly realized the robot toy was kinda shitty but hey this console is pretty rad. R.O.B was a shitty peripheral, but he was never MEANT to be a good peripheral. His secret quest was to save the video game market in the US, and he was successful. Bless you, R.O.B "
