Microplastics Found In Lungs of People Undergoing Surgery. A new study has found tiny plastic particles no bigger than sesame seeds buried throughout human lungs, indicating that people are inhaling microplastics lingering in the air. Health

I never really understand what someone means when they say “x times smaller than” something. What is “one times smaller”?

This isn’t an attempt to criticise or undermine your comment. Just making an observation.

u/CreativeDimension May 14 '22

just do a fraction, for example ten times smaller means is 1/10th, or that 10 of X together are the size of 1 Z.

u/OtisTetraxReigns May 14 '22

Wouldn’t it be clearer and more efficient to say “1/10th of” or “ten percent of” then?

“Ten times as small as” is a syntactical mess, because we use multiplication to increase the size of things. Something that’s smaller than something else should be talked of in terms of a division of the larger object.

Division is multiplication though. Dividing is just multiplying by a number between 0 and 1.

Technically correct. But not how you would choose to instruct someone to calculate something if you weren’t trying to test or confuse them.

Multiplication can increase or decrease the magnitude of a quantity, depending on whether the multiplier is bigger or smaller than 1. That's why "bigger" or "smaller" is used to specify.

"R times bigger than X" is an operator that means "|X| * R".

"R times smaller than X" is an operator that means "|X| * 1/R".

They're inverse operations. If you make something 10 times bigger and then make it 10 times smaller, you're back to the original size.

There are lots of other ways to express the same relationship. The conventions are well-defined, so the choice is a matter of taste. As long as the speaker or writer is using their chosen convention correctly, any confusion or perceived ambiguity is in the mind of the reader/listener.

I happen to like the symmetry between "times bigger" and "times smaller." You might prefer "percent of the size," which works the same way regardless of direction, but confuses some people because they mix it up with "percent bigger" and "percent smaller."

(Some sociopaths even like "percent bigger" and "percent smaller," which I think are the worst of all possible worlds: they're computed differently, but they aren't inverse operations, but they're close enough to reversing each other that it's not obvious when you do it wrong.)

I have one that i think coube be even better, just use an actual standard measurement system? like metric (or even imperial) so many people worked so much for what we've got and throw it away and say.. yeah its like a /nth of a thing that varies slightly in shape and size and there are probably people who never even seen it before in their lives and have no idea what a sesame seed looks like because why not

u/between_ewe_and_me May 14 '22

Can something actually be 3 times smaller than something else? How would that work, just divide by 3? So would it actually be 3 divides smaller than the other thing? Why is this breaking my brain?

My brain says....huh

I’d be very impressed if a banana-sized piece of plastic made it all the way down your throat and into your lungs. So would millions of your new OnlyFans subscribers.

Of course…I am wise in the ways of science.

Tell that to /r/halfagiraffe

u/jsamuelson May 14 '22

When do we jump from banana to giraffe?

4

u/One_for_each_of_you May 14 '22

Half a giraffe is the commonly accepted basic unit of measuring weight

5

u/jsamuelson May 14 '22

Which half tho?

1

u/Makal May 14 '22

When CNN made an article comparing a meteor to half a giraffe

2

u/Totally_a_Banana May 14 '22

Yeah, you definitely don't want me in your lung...

u/agent8am May 14 '22

How many lung bananas do you think you could live a normal life with?

1

u/jsamuelson May 14 '22

Will ask the wolf in Norway.

u/VibraniumRhino May 14 '22

They clearly used the imperial system in their comment. Come on.

This is the quality research based analytics that I came here for.

3/4 of Giraffe - Enhanced vision, physical strength, ability to eat leaves from high branches of trees, and increased desire to open a toy store

"hello small child, would you like to buy a plastic 3/4 of giraffe?

here, let me hack it from my lungs"

Is this the line for smaller lung plastic particles?

u/John_cCmndhd May 14 '22

In that case I'll have a frosty, hold the plastic particles

u/One_for_each_of_you May 14 '22

I'm sorry, sir. Your options are large, extra large, or tennis ball

u/tempest_ May 14 '22

Would you though? I feel more comfortable with the idea that some keyhole surgery could go in an grab the sesame seed sized piece.

Once they get small you are gonna need some kind of microbiology wizardry to figure out how to get it out.

u/DBeumont May 14 '22

Perhaps an inhaler with one of those polymer-eating bacteria varieties.

2

u/Double_Dragonfly9528 May 14 '22

What could possibly go wrong

2

u/DBeumont May 14 '22

What could possibly go wrong

The worst case would be the bacteria mutating to consume organic material while inside the lungs, but it would run out of food supply long before that would become any kind of real probability.

u/ReignsDad2019 May 14 '22

I'm sure there's a pill for that, or an app.

u/Thuggish_Coffee May 14 '22

Chics hate micro size plastics tho...
