The Most Misunderstood Concept in Physics
Earth receives a steady stream of energy from the sun, but the deeper mystery is what that energy *doesn’t* do: it doesn’t simply vanish, and it...
Did The Past Really Happen?
A dog’s grave can be erased by a highway—and that small, human-scale loss points to a bigger question: how can anyone be sure the past happened, and...
Solving Wordle using information theory
Wordle can be treated as a problem in information theory: each color pattern (green/yellow/gray) functions like a noisy “measurement” that reduces...
What is NOT Random?
The universe isn’t “random” in the everyday sense—many outcomes are predictable—but the arrow of time and the limits of prediction point to a deeper...
Oh, wait, actually the best Wordle opener is not “crane”…
A subtle bug in the Wordle-simulation code changed which opening word comes out “optimal,” overturning the earlier claim that “crane” is the best...
The Impossibility of Perpetual Motion Machines
Perpetual motion machines fail for a simple reason: every proposed design ultimately breaks a law of thermodynamics—or, at best, can only run down to...
Why Doesn't Time Flow Backwards? (Big Picture Ep. 1/5)
Physics at the microscopic level treats past and future symmetrically: equations like F=ma, gravity’s inverse-square law, and Schrödinger’s equation...
Are You a Boltzmann Brain?
Boltzmann brains are a thought experiment that turns the second law of thermodynamics into a question about personal existence: if the universe’s...
The Misunderstood Nature of Entropy
Entropy’s core claim is simple but far-reaching: in an isolated system, entropy tends to increase, which effectively sets the universe’s “arrow of...
Why Do You Remember The Past But Not The Future?
Physics treats time as directionless: the equations governing motion run just as well backward as forward. Yet human experience is sharply...
The Arrow of Time and How to Reverse It
Physics treats time as directionless: reversing every particle’s motion and rerunning the governing equations predicts the same kind of “rewind”...
Fermions Vs. Bosons Explained with Statistical Mechanics!
Statistical mechanics turns the messy motion of countless particles into a counting problem: the macroscopic “rules” of thermodynamics emerge because...
Good news for faster-than-light travel. Bad news for time travel.
Time travel through a wormhole-like “time loop” runs into a quantum-level constraint: the only consistent past-return scenario requires the system to...
The Man Who Built the Second Brain Movement (Tiago Forte)
Thiago Forte’s “agency” framework boils down to a simple but demanding idea: when something feels bad, confusing, or stuck, the fastest path forward...
Thermodynamics || Lec # 3 || Second Law of Thermodynamics || Dr. Rizwana Mustafa
Second Law of Thermodynamics pins down not just whether energy can move, but the direction and limits of that movement—especially for spontaneous...
