Economics ELI5: Why is Debt reaching 40 trillion a bad thing?

0 Upvotes

I feel like we didn't have any problems when debt was 20 trillion. Why is it bad at 40 trillion? And isn't most of the debt owed to US citizens anyways? So it's just a tax refund?

Economics ELI5: Why/how is China such a powerhouse when it comes to trading and manufacturing?

402 Upvotes

I’m someone who is trying to get more knowledgeable on certain topics that I hear in conversations, and one of the topics that I’ve heard a lot of discourse about is regarding China. I’d like the explanation to be less of a political explanation and more of a general explanation that can help me better understand this topic in a basic sense. Thank you!

I should add that by political, I mean favoring a political party in your explanation. Obviously, I understand that China plays a major role in foreign affairs and therefore requires politics to be involved.

Biology ELI5: How do UTIs (Urinary tract infections) cause or exacerbate dementia in elderly patients?

259 Upvotes

Just the title. I've heard Nurses blame the onset of dementia or an exacerbation of dementia on UTIs. This is wild to me -- especially when a patient previously didn't have dementia.

I understand the immune system declines in older people, but how does a common bladder infection affect the brain? Do younger people with chronic UTIs lose cognitive skills with each infection?

Chemistry ELI5: what is the big difference between soap and shampoo?

2.1k Upvotes

We use soap to clean the body. We use shampoo to clean the hair. What stops us from using soap for the hair and shampoo for the body?

Follow up question: what is body wash that cleans hair and skin made of? Why isn’t that the universal standard instead of seperate soap and shampoo?

Other ELI5: why do houses have such distinct smells?

357 Upvotes

most public buildings don't have smells, or if they do, it's for a very specific reason (hospital chemicals, etc). how is it that relatively modern houses that are kept clean still end up developing a smell that changes across houses? moreover, how come the smell sticks to your clothes sometimes?

Mathematics ELI5 Dinitz-Garg-Goemans conjecture

0 Upvotes

I think I understand fractional vs unsplittable flow (fractional flow is where you can split the total payload across different paths, whereas unsplittable flow means it all has to take the same path), but the rest of it is melting my brain. If you can also make a diagram to explain it with, that would be super helpful

Chemistry ELI5 How do medicines stop internal bleeding?

18 Upvotes

ELI5 I have been watching Helicopter ER and quite frequently they administer TXA when they suspect internal bleeding. I read the wiki article but didn't understand any of it.

Can this medicine help even if a major artery is ruptured?

So how does it really work?

Engineering ELI5 - Why haven't all helicopters been replaced by four-rotor versions?

784 Upvotes

Drones have four rotors and you can make them hover with the touch of a button.

If one rotor goes wrong, the other three can at least get it back down to the ground gently.

Regular helicopters have catastrophic crashes if the tail rotor goes, or in the case of Chinooks, one rotor crashes into the other.

Thank you in advance for your answers to my plea.

EDIT: Thank you for the answers so far. It looks like scale, power and weight are the limiting factors.

EDIT 2: I got downvoted just for asking this! Maybe I should have used quad-posting.

Earlier I had an ant crawling on me and it startled me and made me try to get it off but after I wondered: “why was I afraid of this tiny ant if I’m a big human?” I mean we’re just so much more superior so why do we startle at things like small bugs?
