Smart People Share Senseless Ideas That Can Be Proven Mathematically[rebelmouse-image 18356273 is_animated_gif=
Math was never really my strong suit, but I do understand that some stuff just needs numbers to make sense. Not sure what I'm talking about? Leave it to Reddit to explain it way better than I ever could. One Reddit user asked:
What are some things that make no sense but can be proven mathematically?
I'm still not 100% sure of the math that goes into explaining why one pizza might be more pizza than two pizzas or why straws don't work in the moon - but I feel like if SpaceForce is going to be able to do SpaceLunch these are just bits of knowledge we all need to have. Prepare to have your mind blown by stuff that makes little-to-no sense in the real world, but math says is perfectly normal.
The Perfect Sphere[rebelmouse-image 18360101 is_animated_gif=
The Banach-Tarski paradox is a nice example of something that exists because of mathematical objects that have no correspondence in reality. If you have a mathematical perfect sphere and cut it in ways that are only possible in mathematics (single points do not exist in reality), you can rearrange it to get two spheres. And that is just one example of what messing with infinity can give you.
The great Polish sci-fi writer Stanislaw Lem in his book "Summa Technologiae" wrote that mathematics is like a mad tailor, making all possible sorts of clothes. Some of them fit humans, some fit trees or octopi, some fit creature that exist but we haven't met yet; and some just don't fit anything in our universe. Mathematics makes theories that seemingly have no point in physical reality; that might be so, or it might be that we just haven't discovered a way to apply them. Number theory was thought to be useless until cryptography came along.
Monty Hall[rebelmouse-image 18360102 is_animated_gif=
The Monty Hall problem's solution doesn't make sense until you start adding tens or even hundreds of doors.
Here's my attempt:
3 doors: 1 goat, 1 car, 1 nothing. Your chances are 1/3 to choose the car, yes? There are still 3 doors.
3 doors, goat is shown. 2 unknowns. There are still 3 doors- your original probability DOES NOT CHANGE because of this. It's still 1/3 chance. This is the part where I got stuck before. There are still 3 doors, your chances are 1/3.
Acting on the information though by swapping ADDS the 1/3 chance by knowing it has a goat behind it will ADD the probability together. 1/3 and 1/3 together. Making 2/3. The important part is acting on the information. However, if you had no outside knowledge, aka if your friend comes after a door is opened, his chances are 1/2 because he doesn't know. By opening a door for you, the dude 'adds value' to the door that isn't chosen by you but not to the one chosen by you originally.
So another way of thinking of it is NO MATTER WHAT choice you had made originally, you had 1/3 chance of winning. What's left is 2/3 right? If you abandon your original choice and jump ship to the other pool, your chance doubles.
How Much Rope?[rebelmouse-image 18346795 is_animated_gif=
The old rope-around-the-earth trick.
Imagine you have enough rope to go all the way around the earth's equator (ignoring mountains, etc). Now assume that you'd like to have that rope be 1 meter off the ground all the way around the earth. How much rope would you have to add?
A New Deck Of Cards[rebelmouse-image 18360103 is_animated_gif=
If you take a deck of new cards and shuffle it, chances are good that's the first time that sequence has ever existed on earth. 52! Is a long number.
No Straws On The Moon[rebelmouse-image 18360104 is_animated_gif=
This is less math and more physics, but straws don't work if they're taller than a very certain height - and they don't work at all on the moon. In order for liquid to flow through a straw, the inside of your mouth needs to be at a lower pressure than the outside air. If there is no outside air (like, say, on the moon for example) your mouth can't be at any lower pressure.
Pizza Math[rebelmouse-image 18360105 is_animated_gif=
One 18" pizza is more pizza than two 12" pizzas. One 17" pizza is almost exactly two 12" pizzas by area. However, the two 12" pizzas will still have about 30% more crust than the 17" pizza. So if you're going stuffed crust, go small.
Global Temperature[rebelmouse-image 18360106 is_animated_gif=
When I was in uni, we had a calculus temp/sub prove that the temperature here and a spot exactly on the opposite side of the earth, are the same.
If I recall correctly, he took 2 classes to write it on many many chalkboards. We were mostly in awe of his handwriting, and later found out he was allowed to turn in his thesis in handwriting, rather than typewritten. Before anyone questions, his thesis was not what he burned our time with.
It is the Borsuk-Ulam theorem in topology: for a continuous mapping of a sphere onto a plane, there will be two points which were antipodal on the sphere and are the same point on the plane. In fact, we can pick two continuous variables here: say, temperature and atmospheric pressure. Then it is a mapping between the Earth's surface and a temperature-pressure plane, so there will be two antipodes that have the same temperature and atmospheric pressure.
Happy Birthday![rebelmouse-image 18348437 is_animated_gif=
The birthday paradox.
Get 23 (randomly chosen) people in a room. It is decently likely that 2 of the 23 people share the same birthday (discounting year).
I am a mathematics graduate, I understand the mathematics, yet there's still a part of my brain that is thrown by this logic!
For anyone intrested: the idea is how many times you compare 2 peoples birthday or, in other words, how many unique parings of birthdays you have. The first person has 22 people to compare their birthday to, 2nd one has 21, therefore you have 22+21+20....+1=253 unique parings. Chances of a pair to be identical is 1/365 (disregarding leap years):
(1-1/365)^253=0.4995 or about 50%
The Speed Of Light[rebelmouse-image 18360107 is_animated_gif=
Light moves at the same speed for everyone.
If you're moving away from the light, or moving towards it, doesn't make a difference, it's still travelling the same speed for you
Roulette[rebelmouse-image 18360108 is_animated_gif=
Gambler's fallacy - patterns of independent events do not dictate future results. I know it is true but still fall for it.
When a fair roulette table lands on black 10 times in a row it is just so tempting to keep putting money on red.
"What makes someone bad in bed?"
WHERE TO BEGIN?!
The list is endless.
Half the time all it takes to be better is a little effort.
RedditorMidoriSpicewanted to hear about the lack of skills some people really need to acquire when it comes to sexy time. They asked:
"What makes someone bad in bed?"
I love sex. But it can be stressful. I've always found connection to be one of the best lessons.
CommunicationsGIF by HULUGiphy
"Assuming they already know what their partner wants/likes and doesn't communicate or take any instructions."
Take it Slow
"No foreplay and not caring if your partner is enjoying it."
"I had an ex who literally never wanted to do any kind of foreplay. He just wanted basically sex of any kind for him. He said oral on women was gross."
"Proposing mid intercourse."
"Honestly? With the partner I have, I'd think it was pretty hot and romantic lmao. I'd check in after the deed to make sure he was serious but our relationship is already very serious so it wouldn't be a big deal."
Talk to Me
"Not talking or making any noises. We don't have to dirty talk the whole time or even at all but you gotta let me know you're enjoying it at least."
"I think there's some balance between having some small talk, silence, and dirty talk while being in bed with someone. Or maybe that's just been my experience. I don't know--I think there's some fun in trying to carry a side conversation while having sex lol."
"Friction isn’t always a good thing."

"To this you can add unclipped fingernails."
"And dirty fingernails. Nah, ma'am. I’m betting this is not worth the infection. Thanks."
‘good at sex’
"I have a feeling most men will say 'lack of enthusiasm' and that most women will say 'being selfish about pleasure.'"
"I’m a woman and my first thought was lack of enthusiasm, but my own lack of enthusiasm. The only bad sex I’ve had is when I don’t genuinely want to be there. I’ve had sex with guys who weren’t ‘good at sex’ but still enjoyed it because I was really into them."
"They are convinced they know more about what works for you than you know yourself. Just cause your ex-lover Pat liked technique X doesn't mean everyone does."
"Have experienced this, it sucks. He wouldn’t listen to what I enjoyed, didn’t want me to say ANYTHING even if it hurt or wasn’t working, and would just say something along the lines of 'every other woman I’ve been with liked it.' I’m thinking, all you’ve had are one-night stands, really, so they probably didn’t say anything."
"I’ve had numerous partners and love sex. Crashed and burned with this one and he really crushed my self-esteem and sexual confidence."
"The biggest thing is always going to be selfishness and the inability/refusal to communicate and listen to your partner. I've seriously had a guy yell 'I KNOW HOW TO DO IT!' when I was trying to tell him how I liked whatever he was doing. He then got even more upset when I said 'did you just f**king yell at me? Alright, off, I'm done.'"
FlavorsAmanda Seales Wow GIF by truTVGiphy
"Lack of variety. Don't get me wrong, I don't mean crazy kinks or positions from the karma sutra, but more when it's really predicable. I has an ex that had this weird routine of positions, it was exactly the same every single f**king time in exactly the same order."
Sex. Let's be better at it.

Love is so elusive these days isn't it?
Who knows what anyone is looking for in the relationship department anymore.
It's all too exhausting.
But people we keep trying.
RedditorProblemNice5257wanted to hear why so many people are still on the hunt for that perfect one. They asked:
"Why are you single right now?"
I'm single because I've given up. And I'm good. For now.
PeaceSnoop Dogg Reaction GIFGiphy
"I put absolutely no effort into meeting someone."
"Same! Also it's extremely difficult when you feel so at peace being by yourself. The fact that I have to find someone whose presence outweighs my level of comfort being alone seems impossible."
"Hard to meet people when you are a hermit."
"Yeah, I describe myself as a shut-in, lol. I leave my apartment to work, I leave my apartment to buy food, and occasionally I’ll bring out the trash, otherwise I just watch Hulu, play online chess, surf Reddit."
"Same. I've spent months trying to find an apartment I can afford without a roommate and finally settled on a small studio apartment for $1100 a month because I'd rather living in a tiny space and be left the hell alone than share a much nicer place even with a good friend."
"I have too many unsolved issues, i can't in good conscience bring someone else into them."
"Idk your issues but everyone's got some crap. Not sure how unique yours are but everyone's got some crap. It's good to share some of your struggles with other people. Just don't open with it haha."
"Issues unresolved or not, (in my case) only makes it worse when you feel like you could open up to them, and they just take those to use it against yourself afterwards."
"I hardly go out and expose myself to people. I'm uncomfortable with the notion of myself being in a relationship at this point. Also, I'm very dry in terms of personality."
"I spent a year entirely isolated due to covid and now I can't handle physical contact. It makes me really uncomfortable and a hug is enough to make my body shut down. I'm hopeless."

"I'm attracted to many, and unattractive to all."
"Last relationship was so toxic, I've sworn off dating, at least for awhile. I haven't had this much free time in ages. It's nice."
"Edit: Hey, it's really great hearing from so many people with similar experiences. Like many of you, I've been taking it in stride and focusing on bettering myself, both physically and mentally. It's done wonders for my health and I feel a whole lot better. I wish y'all the very best. Stay excellent, my friends."
"I'm 35yr old single father to a 5yr old and I work nights. It's hard to find free time to meet someone, especially in my area. If I do have free time to myself, I like staying home and ordering a pizza while drinking some beers and playing video games. I pretty much faced the fact that I will probably be alone for the rest of my life."
"I was in an 8 year relationship (married for two) to my high school sweetheart. Exactly this same time last year, we got divorced because I found out he was cheating on me with my best friend. The best friend I had known LONGER than him and was friends with since fourth grade."
"She was living with us to try to get back on her feet. Yeah lol. So I lost my best friend and the man I had been with for 8 years within the same night. So I moved to another state, got an apartment by myself, and am now single and divorced all by 26. Not really looking unless the right person comes along."
"It’s pretty happy and peaceful now that they’re both out of my life though honestly. You realize people’s toxicity and flaws the most once you get space away from them."

"Because my relationships end before they even begin."
"This is my story right here."
Alright. Now that we've laid out all the excuses, let's get to matching with some people.
There is no bigger mystery than what happens to us after we die.
But even those who don't practice an organized religion tend to believe that there is a Heaven, a happy joyful place where our souls will remain for eternity.
No two people share the same idea of what heaven would be like, but everyone who believes in it probably has an idea of the first thing they'd do after entering the pearly gates.
Redditor WeDidItGuyz was curious to hear what would be top on everyone's list upon entering the afterlife, leading them to ask:
"If heaven exists, what’s the first thing you’d do?"
Overcome with joy
"In all reality?"
"Probably cry for about 30 minutes because the biggest existential fear at the very core my humanity has now been lifted."
"If Heaven exists, like 50% of the awesomeness is just the very fact that it exists."heaven gate GIF by South Park Giphy
A re-match long in the making
"Ask my childhood friend Kevon for a race."
"He used to beat me handily when were younger (9-13) and he’d always brag."
"When I got older and faster I moved away so I was never able to race him again."
"We arranged for a race but he was shot multiple times and bound to a wheelchair until he passed a few years ago."
"I wanna race him both in our prime."- Abethegreat1

Who knows what's in store for us after our lives come to an end.

"Fun facts" generally refers to a tidbit of information about a specific topic which the general public might not have otherwise known about.
But the first word in that term can be misleading.
Indeed, some "fun facts" reveal information that isn't remotely "fun" in the slightes.
Redditor Alternative_kachocho was curious to hear some "fun facts" which were anything but fun, leading them to ask:
What's a 'fun fact' that isn’t fun at all?"

They'd still be here if they weren't so delicious...
"The giant tortoise was so delicious, it caused not only itself to be hunted to extinction, but also the dodo."
"Giant tortoise meat was supposedly better tasting than chicken."
"It's fat tasted better spread on bread than butter."
"Also, it was the perfect food for sailors at the time, as their bladders stored 1 litre of purified water, and they could survive without food in hibernation for almost a whole year in the hull of a ship."
"Not to mention, because they evolved without humans, they were easy to hunt."
"You could tie one to your back, and roll another to the ship and they would just let you."
"It was so delicious, they went unrecorded for a long time because expeditions to bring living samples of wildlife to Europe kept eating them on the way."
"Conversely, the dodo, while as easily captured by sailors, tasted awful."
"It was completely unpalatable."
"HOWEVER, one day, someone discovered if you cooked dodo meat in the more delicious tortoise fat, it tasted just like chicken."
"So now, sailors were hunting a few tortoises at a time for their fat and water, storing them, and then hunting dodos on the daily."
"Overhunting, plus the introduction of rats to the environment (because sailors) which would eat eggs, led go the population to decline at a rate they could not breed to keep up, leading to both animals going extinct."- Kyhan
Don't forget the nose plugs

It's hard not to read some of these "fun facts" and wonder if there should be an alternative term for the facts which aren't fun.
Oh yeah, probably not....
