Susskind Physicists Tier List 2025

That look of pure mathematical betrayal! The small angle approximation (sin x ≈ x for x near zero) is actually a legitimate mathematical shortcut used in physics and engineering. But to a math major, this is like saying "2+2≈4.1 is close enough." They've spent years proving theorems with rigorous precision only to watch someone casually commit mathematical heresy. The Taylor series expansion of sin(x) is x - x³/3! + x⁵/5! - ..., so technically the approximation has some merit, but that death stare says "I didn't suffer through Real Analysis for you to butcher calculus like this."

The perfect quantum physics explanation doesn't exi— Quantum mechanics: "Imagine something that's exactly like a familiar classical object, except it's completely different and breaks all intuition." That's electron spin in a nutshell—except it's not in a nutshell, because that would be too straightforward! What makes this brilliant is that electron spin is actually an intrinsic angular momentum that has nothing to do with physical rotation. The ±½ values represent spin quantum numbers that determine magnetic moment direction. Physicists spent decades developing this mathematical framework only to explain it with "it's like a spinning ball that's not spinning and not a ball." Physics professors everywhere: "Did I clear that up? Great, next topic!"

Engineers live in a world of practical approximations—"close enough" gets the job done! Meanwhile, mathematicians are having an existential crisis if you dare suggest that a spherical cow in a vacuum isn't pure blasphemy. The title "Assume Silver Is An Ideal Gas" perfectly captures this divide—it's the kind of simplification that would make an engineer nod while causing a mathematician to scream like that cartoon rat. Pure math demands ABSOLUTE TRUTH, while engineering just needs something that won't collapse or explode... usually.

The chemistry version of "send nudes" is apparently "send nodes"! This brilliant pun plays on atomic orbital diagrams showing 1s, 2s, and 3s orbitals with their characteristic spherical probability clouds and nodal surfaces. In quantum chemistry, these "nodes" are regions where the electron probability is zero. So basically, this person is flirting with their girlfriend using electron orbital diagrams. Talk about finding romance in the quantum realm! Next time you want to impress your chemistry crush, forget about sending flowers—just send them your favorite atomic orbital nodes. Because nothing says "I'm attracted to you" quite like electron probability distributions!

Schrödinger would be proud. Here's a cat simultaneously existing on a scale yet registering zero mass—the perfect quantum superposition. In quantum physics, particles exhibit wave-particle duality, existing in multiple states until measured. Much like how this cat seems to defy the scale's measurement while clearly being present. The ultimate quantum loophole: if you don't register on the scale, those treats technically added zero calories.

When you're so deep in physics notation that you write seconds as "kilogram-meters squared per seconds squared" instead of just "s"! This is the SI unit formula for seconds derived from dimensional analysis (kg·m²/s²), which is like ordering a coffee by listing all its molecular compounds. Only physics students would torture time itself this way! Next time your professor asks "how long did the experiment take?" just reply with this equation and watch their soul leave their body.
