• 🌞 Earth gets heated by the Sun. But hey! Not all parts get the same amount of love (or heat).
• Why? Blame things like geography and those fluffy clouds.
• 🔥 Hot Land/Sea: Air above rises, creating a low-pressure party.
• ❄ Cooler Spots: Air falls, and a high-pressure club is formed.
• Air hates FOMO (Fear of Missing Out) so it moves from high pressure to low.
• 💨 This movement? That's wind for you!
• 🌍 And Earth's rotation? It brings the Coriolis force into the mix.
  • Result? In the North: air goes clockwise around high pressure.
  • In the South: it's a counter-clockwise dance.

🌍 Real-world example: Think of a merry-go-round. If you try to walk straight across it while it's spinning, your path seems curved because of the moving platform underneath. Earth's rotation does something similar with winds!

• Morning ritual: You blow on hot coffee. Why?
  • Helps cool it faster. How? Enter, forced convection.
  • You're speeding up energy transfer, making the coffee say, "Brrr!"
• Newton's Chilling Fact: Newton had a cool (pun intended!) law. The rate a body cools is linked to the difference in its temp (θ) and the surrounding's temp (θs).
• Formula magic: dθ/dt ∝ (θ – θs).
• Radioactive Déjà vu: Just like radioactivity has a half-life, so does cooling.
  • What's cooling half-life? Time taken for the temperature difference to be slashed in half.
• When old meets new: Maruyama & Moriya in 2020 gave Newton's 1692-3 experiment a try.
  • Result? Newton rocked! His measurements were on point.

🔥 Real-world example: Cooling half-life is like melting ice cream on a summer day. Even if it's kept in shade, it'll melt, but the rate might just halve if you cover it!
