Physics that can save you

Bro didn’t the first guy die?

if someone stabs you, call 911 bro

Physics? That's cool and all, but can it help me find my lost socks?

How does that relate to physics?

Yes ,it's save

Physics is human's bff Using kinetic energy to life a tire easily

These are actually legit trauma hacks taught in tactical/first responder courses: 1. Occlusive dressing (plastic + tape on 3 sides) → flutter valve effect. Lets air escape on exhale but seals on inhale → prevents tension pneumothorax. Standard in TCCC/TECC protocols. 2. Needle decompression (14–16G needle, 2nd intercostal mid-clavicular line) → releases trapped air under pressure. Can buy 20–60+ min until a chest tube. 3. String trick for rings → pure friction & lubrication physics. Works surprisingly well before fingers turn purple. 4. Pressure bandage layering → applies even pressure without tourniquet-level risk of cutting off circulation. Crazy how much basic physics shows up in life-or-death situations. Still, call 108/911 immediately — these are bridges to proper care, not replacements. Anyone actually tried the ring one IRL? 😅 (And yeah, the first scenario guy would still need urgent surgery, but the seal dramatically improves his odds pre-hospital.)

So do I need to tape the wound or not?

@grok, is this really a good method to save this guy?

I'll remember this next time a ninja impales me with a flying knife, thanks. Gotta keep my tape and plastic on my pockets

A sucking chest wound

The physics that saves the intestine

the magic of physics is wild

Who tf is gonna cover the wound?

the main thing is not to mix it up. a man got his lung punctured and he’s like, okay, I need to wrap a rope around my finger or something 😂

@grok would this work?

Ok how about the blood?

What did you make me watch bro ?

This is false. This would cause the chest cavity to fill with air, requiring a needle chest decompression. If it had an entrance and exit wound, it would need one side flutter valve, one side sealed. The recovery position is correct.

What is going on here ?

I don't live in London

@grok Is this real for saving human beings?

Science Accuracy Meter: 3/10 ⚠️ “Physics can cure all diseases and replace medicine.” Physics is super powerful for tools (like MRI, X-rays, radiation therapy), but it doesn’t “replace” biology, chemistry, or medicine. It’s one piece of the puzzle, not a magic fix for everything. • MRI, CT, PET use physics to see inside the body (Lauterbur & Mansfield, Nobel Prize 2003) • Radiation therapy uses physics to target tumors (Hall & Giaccia, 2019, Radiobiology for the Radiologist) • But diagnosis, drugs, surgery, immunology etc. come from other sciences working together If you want a more in depth analysis of this claim or if you’re curious about other scientific topics tag me @eli5xt and ask me your questions.

Why am I lost

A fucking hair transplant is neither physics nor life threatening

Onde que eu vou achar essa geleca enquanto eu estiver morrendo?

First rule of First Aid to a knife-attacked victim-- DO NOT remove the knife. Wait for professionals.

Lesson learnt!!
