When the great pyramids were being built there was still woolly mammoths walking the earth.
Humans can’t feel wet, what we’re actually feeling is cold. It’s why when you have a cold patch on a blanket or carpet you can’t quite figure out if it’s wet or not.
It’s possible to define an infinite sequence whose nth term must exist before it’s first.
do it now…
Let $\mu(x)=0$ if $\exists y<x\mu(y)=0$ or $x$ is the 20 millionth prime. $\mu(x)=\mu(x+1)+1$ otherwise. The elements of the sequence only become defined once the 20 millionth prime is found; till then they’ve yet to be constructed.
Bonus: The sequence $\nu$ is defined as follows.
Let $\nu(x)=0$ if $\exists y\leq x\mu(y)$ is perfect. $\nu(x)=\nu(x+1)+1$ otherwise.
We’re not sure if this is a sequence, even though it is algorithmically definable. Its existence relies on the existence of an odd perfect number.
There are more atoms of hydrogen in a molecule of water than there are stars in the whole solar system.
So, more than the 1 star in our solar system? Did you type that right?
Correct. I essentially said 2 is bigger than 1.
Ha! Good one, I only caught half of that joke.
If sound could travel through space, from the distance we are to it, the sun would be as loud as a jackhammer everywhere on the planet, all the time.
Everyone knows you jump in the pool in summer, smell the chlorine, and know the water is clean, right?
Fun fact- chlorine dissolved in pool water at the usual sanitation levels has almost no perceptible smell or taste.
HOWEVER, when chlorine binds with certain organic substances, especially ammonia (from the urea in sweat and urine), the result is chloramine which has a significant chlorine-y smell. Chloramine has essentially no disinfecting properties.So when you go to the public pool and get a whiff of chlorine and think ‘man they’re using a lot of chlorine today’, no, it probably means someone peed in the pool.
You’re welcome :)
Ok, but why then when you open a bottle of bleach or container of chlorine pellets, does it smell like chlorine. Do they add the piss ahead of time?
take all but 1.5mL out of that gallon jug of household bleach, then fill it back up with water. that’s roughly the concentration of chlorine in a swimming pool.
Try swimming in bleach and see how it compares
That’s pure chlorine, much higher concentration. At the concentrations of pool chlorination there’s essentially no smell.

Whelp… yet another thing to add to my never have again list.
Multiple species have evolved into crab body plans, and only a subset of “crabs” are actually true crabs. For example coconut crabs evolved from a hermit crab ancestor. King crabs too.
The tendency to adopt the crab meta for your species is called carcinization.
There is no thru line from mouth to urethra. You drink water, it gets absorbed into your blood, your urinary system filters excess water and waste, you pee it out. Your pee is filtered blood, the only thru line for water to take from your mouth is your ass. I understood that when it was taught, but I didn’t really think about it…
Piss comes from blood!
Does the blood god accept pee? Your move, “science”!
The people who got anime to take off in the US are the same people who started the furry fandom.
The Superman symbol was based off of the symbol for a sci fi fan club.
Conventions, and sci fi as we know it, are because of one electronics magazine.
Useless knowledge.
When playing Mechwarrior 2 on a Windows 2000 system, make sure to change your video mode to 32bit color.
I’ll throw in a useful tip too!
You can buy USB foot switches for your computer and assign keystrokes and other functions to them.
Almost feels like cheating when you are playing a tactical shooter and can lean left or right and strafe on demand without crossing any controls. Having microphone activation, map, inventory, or any number of misc actions boud to a foot pedal makes a huge difference in your ability to play a game.
Further knowledge about Mechwarrior 2: 31st century combat:
At various stages in the campaigns, you’ll face off against Elementals, escort a Tarantula, and fight a Battlemaster. Through cheat codes, you can add these to the mech lab and play in them in the “Trial of Grievance” free play mode. The Elemental works fine, it functions as a tiny mech, the Tarantula works mostly correctly, but it isn’t 4-legged. It looks like it is but the front two legs are legally arms, they can be blown off and it works fine. Trying to select the Battlemaster in the mech lab will immediately crash the game.
Cheat codes for Mechwarrior 2 were the very, very first thing I searched the internet for.
Dishonorable conduct, Wetnose.
lol the drill sergeant character who spoke almost entirely un-clanlike, other than occasionally using the term “freebirth”.
I don’t know. Sounds kind of useful to me.
Probably more difficult if you have pets
Nah, my snakes don’t really mess with the foot pedals.
The continents move at roughly the same speed that your fingernails grow.
That’s fast! They must take their supplements!
The guy who did localization for the Zambak magazine’s Turkish translation of “the alice in wonderland” has the cool birthday January 1st, 1969.
(Might’ve been another magazine, could not find a picture online)
The gorgeous Lunar Moth exits the chrysilys fully formed, without a mouth or other structure for the intake of nutrients. It only exists to fly and breed at that point and expires around a week later.
Man, spends his whole life starving to death.
Ketchup, or catsup, which is the same word latinized differently, was a fish sauce from China.
The western Europeans and American colonists used the recipe, and expanded it to things like mushrooms and many other ingredients. (for proof, look at the ketchup entry on wikipedia).
Tomato ketchup (which is specified on your bottle still today) wasn’t invented until we realized that tomatoes weren’t poisonous despite their color, and their sweetness and tang totally rocked with the ketchup recipe.
Now we use it to eat frenched fries, which aren’t French! In fact, they are Belgian, and are named because they used a cooking technique invented by the French called “frenching” which has evolved into deep frying.
So, you are dipping your belgian potatoes into a chinese sauce that use a North American fruit as a base.
And with this information, you shall father nations!
It also took a long time for tomato ketchup sales to take off because it was very difficult to make shelf stable for transporting and selling in stores. Heinz was the first company to make one that sold well. Before that, tomato ketchup was typically made at home if you wanted something vaguely decent.
Thank you. This sounds like the kind of useless knowledge I can use.
And in the Philipines, ketchup refers to a banana ketchup, not a tomato ketchup.
That picture of mushroom ketchup is vile.
I bet that would be bomb on roast beef tho
Albert Einstein was rejected from Swiss army duty for having sweaty feet.
They don’t like people who question things in military anyway. Probably a reason too, why Autism and ADHD are reason for exemption (in Switzerland at least).
