Things that are really weird when you think about them

[Shitshitshitshit]

Someone said to me today that balloons are like a plastic bag of someone's breath...

I'd never thought of it like that before and to be honest it made me feel a bit nauseous!

Do you have anymore examples of things that are actually really fucking weird when you think about it?

This is going to, I hope, blow your mind.

The maths involved in modern aviation relies on complex numbers, ie numbers that are part real and part imaginary.

Numbers that cannot exist in the real world.

What if rocks are actually soft but tense up when touched by something else?

Churches would look like bouncy castles.

Disclosure: I don't know how photographs happen. Will someone please explain like I'm an alien?

For the original black and white photos it is basically shadows. You know how you get shadows when you have a light source and an object and the light doesn't poss through the object but casts a shadow.

If you were to get a piece of light sensitive (photographic)paper and cast the same shadow a latent image would be created, that is an image you cannot see. If you leave the paper and shadow long enough you will see an image but it could take a couple of days.

Instead of waiting you 'develop' the photo with chemicals and then 'stop' the development going further with other chemicals.

X-rays are the same idea but rather than a light source they use, well, X-rays, unlike light this form of radiation passess through structures such as humans.

Yemen this point isn't about colour recognition though. It's about labelling. If the colour I called green looked to you like the colour I called blue we would both go through life unaware. We'd both agree traffic lights were 'green' at the bottom, grass was green and emeralds were green. We'd both agree the sea was blue and some people have blue eyes. But if I could ever look through your eyes I'd see blue at the bottom of traffic lights.

Video games and letting children, especially boys, near them. Video games are addictive, electronic, timewasters that distract children from real life and from learning to read. They have spurious ‘levels’ of difficulty to lure gamers into thinking there is a skill to them but are really only hooking the marks more securely to make the producing company further profit. Many are violent and produce damaging and anti social emotions. Children are angry and miserable when they Yule them or have just stopped using them. They cause rifts in families and poorer people beggar themselves to indulge their sons in something that wrecks their schooling.

Why do we tolerate this abuse of our children? Why do people defend them for children? To me it is like having a sewage pipe connected to the house where the sewage is directed inwards.

Use not Yule. Predictive text.Sorry.

I'm not going to argue the colour point any more, accept to say I simply don't agree that it's possibly subjective, and refer back to BadPenny's post.

We can tell when people are colour blind, and therefore seeing a different colour from the majority.

Colour blindness isn't seeing red as green and green as red, though. It's seeing them both as exactly the same colour (and similar to some shades of brown according to DH's friend who is colour blind)

For anyone weirded out by the fact that you were in your mum once, how about the fact that part of you was also in your grandma once?

The eggs grow in a woman's ovaries while she is in her mother's womb. So the egg that became you was in your gran.

Non human milk - we choose to eat milk or feed our babies milk of a massive mammals young and wonder why we are all so fat!

Religion - someone decided that people should worship predominantly male gods, based on sometimes very random fables, and let that be the basis of what you wear, what you eat, who you are friends with. Then you meet up a couple times a week and sing.

Tanning = star damage, but we still think it makes us more attractive

People on boats that have run into trouble being restrained with the supplies. Cue documentary 'by this time they had been drifting for a month and only had enough supplies to last until March'.

Wtf I'd be starving. And punching people for a mouldy biscuit.

And also: if you are overweight and you work out how many pounds you've gained over your lifetime, and what that equates to in terms of food, it works out something ridiculous like (for me) an extra 500 calories a month. Which makes it impossible that anyone can really maintain their weight through appetite control alone, because no one is that accurate. Just getting up earlier on one day a week could burn an extra 500 cals a month. There must be more to it than simply eating the right number of calories. And yet we're all told all the time that calories in/calories out is so important.

Yes I remember reading when remote controls for TVs came in, that if nothing else changed, just using a remote control rather than getting up and changing the channel would make you put on one pound every year. So in 14 years you would have put on a stone.
Weight control is very very finely balanced.

Why has it taken so many thousands of years to reach this point of advanced technology?....most of which has happened in the last 100years or less

Good point. There are a lot more people alive today than there used to be (as in, the world's population is bigger), so I wonder if that's part of it?

Though sadly only people with a certain amount of privilege have access to the tools, education etc needed to come up with new advances. Imagine how much further on we'd be if we all had equal chances.

Dancing.

Smelling someone else's fart - it was literally up their bum a minute ago

My mind is blown. I'm really not good at maths, so I don't get this at all! If you can write a number down it exists, surely? I mean a number is just a potential quantity of something right? Like 3 bananas or 785315704.598556 bananas. If you can't write it down how do you use it in calculations?!

Yup, mind blown.

Women’s bodies are designed really badly. Your vag is internal, warm and moist and a complete haven for germs. Boobs! Did someone have two milk producing things and couldn’t think where to put them, so stuck them ion the front.

Kissing. Why press your lips together, why not rub elbows instead

Plus the difficulties encountered giving birth (Think it's the worse body type in the animal kingdom for birth).

Also the majority of women don't orgasms during PIV sex. Also many need a lot of build up in order to. A real design flaw.

Money, who thought that we should have pressed metal and paper to get things.

We don't need milk! Why would we be reliant on secretions from another species? Where do cows get calcium from?- plants- We can do the same.

While I believe there are lots of good arguments as to why people in the West don't have to drink animal milk, the 'cows get calcium from plants so we can too' is probably at the bottom of the pile!

It's probably because I've never seen them anywhere else but I can't think of a better place on my body for my boobs to be located 🤣🤣

Televised awards for celebrities. Best actor? Big deal - s/he earned millions doing their job. Emptying bins is a job. But best bin man isn’t a thing.

This - and not just one award for doing it. Several opportunities to win over a whole season, and massive crying and drama if they do/don't win.

I'm pretty happy to do my job without all that fuss to be honest.

clairemcnam but surely its all based on averages. So yes if you get u p earlier one day you might eat more. But that should be balanced out by other days

Get a calculator.

multiply 2 x 2 you will get 4
square root the 4 you will get 2

now multiply -2 x -2 you will again get 4
square root the 4 and you will get 2 not -2.

The square root of 4 is 2 or -2

Now square root - 4 and you calculator will have a hissy fit because you cannot multiply anything by itself and get a negative.

This is where imaginary numbers come in, if you say the the square root of -1 is 'i' (or j if you are an engineer) then you can manipulate it just like any real number.

So now you can get a square root of -4 and that is 2i.

You can never have 2i bananas.

But you ca have numbers that have a real part and an imaginary part, these are complex numbers, so you can have 3+2i.

Although those numbers do not exist in real life you can plot them on a graph, instead of an x and a y axis you have a real and an imaginary axis.

What we're all doing now: overthinking things.

"That for 1000’s of years people have lived without central heating, inside toilets and electricity etc (I know some still do), but we are lucky enough to have all these things. I’m very grateful."

Yes, but some people had running water and central heating many, many years ago, but then it was common not to have it in the 60s and some people still don't. We've gone back as well as forwards.

stealth What I read was how finely weight, exercise and food intake is balanced. So it might average out. But often doesn't if you are fat. It is not about eating more if you get up earlier. It is that if you get up earlier and are therefore more active, that can make you lose weight if everything else stays the same.
So my example of the TV remote for example. TV remotes rather than changing channels manually mean that people have to either eat a tiny bit less or be a tiny bit more active every single day, to avoid putting weight on. It is very finely balanced.

My gran was due to marry someone else, but he sent away and did the dirty on her and, on the rebound, she married my grandad. We came v close to not being here (and weirdly we all wish she hadnt met him and had to deal with him because he's an evil arse and she was the lovelies t person ever.) so we kind of wish we weren't around...!
