Newton's Law of Universal Gravitation* 🍎
-Gravity ek _force_ hai. Har mass wali cheez dusre mass ko kheenchti hai.
F = G \frac{m_1 m_2}{r^2}$
Simple, seedha. School me jo padha tha.
- *Kab use hota*: Rocket launch, bridge banana, cricket ball ka girna — Earth par 99% kaam ke liye perfect hai. Bas Mercury ki orbit ya black hole me fail ho jata hai.

Einstein's General Relativity* 🌌
Gravity koi force nahi. Mass space-time ki chaadar ko daba deti hai, aur cheezen us curve par fisalti hain. Jaise Earth ek trampoline par rakhi bowling ball.
Complex, but zyada accurate.
*Kab use hota*: GPS satellite, black holes, universe ka expansion, light ka mudna. Bina iske Google Maps me roz 11 km ki galti aa

Gravity is a phenomenon... Despite having been superseded, Newton's gravity continues to be used as an excellent approximation.

Matlab Newton "galat" nahi hai — wo bas ek simplified version hai. Einstein ne usko upgrade kar diya. Jaise cycle chalana aata ho toh scooty seekhna aasan ho jata

"Every breath is an exchange. Oxygen in, doubts out."

"Every breath is an exchange. Oxygen in, doubts out."
Gas Exchange in Lungs

1. Oxygen In: You inhale → O₂ fills alveoli → Diffuses through thin walls into capillaries → Binds to hemoglobin in RBCs → Goes to body
2. Carbon Dioxide Out: CO₂ from body comes via blood → Diffuses from capillaries into alveoli → You exhale it out

Why it works so well:
-Alveoli: Millions of tiny air sacs in lungs, like clusters of grapes
- Capillaries: Tiny blood vessels wrapped around each alveolus
- Huge surface area: ∼70 m², about size of a tennis court
- Process: Simple diffusion — gases move from high to low
