How Do Classical And Quantum Physics Complement Each Other?

Classical physics, pioneered by legendary figures like Newton and Maxwell, reveals an orderly clockwork universe with precise mathematical laws governing motion, gravity, and energy. However, in the early 20th century, the emergence of quantum physics uncovered a microscopic realm where uncertainty, probabilities, and spooky connections reign supreme. For decades, these two frameworks seemed…

There are more in this series! We bought them when the beans were born. There's one about rocket science, one about quantum physics, and one with Newtonian physics.

Please Remember

As I post about newtonian physics... quantum physics is still very relevant.

They are relative to one another, though we may not yet fully understand their relationship.

There is also a “gravitational” field: it is the origin of the force of gravity, but it is also the texture that forms Newton’s space and time, the fabric on which the rest of the world is drawn. Clocks are mechanisms that measure its extension. – Carlo Rovelli, The Order of Time

Non-Newtonian Raindrops

Fluids like air and water are called Newtonian because their viscosity does not vary with the force that's applied to them. But many common fluids -- almost everything in your fridge or bathroom drawer, for example -- are non-Newtonian, meaning that their viscosity changes depending on how they're deformed.

The 8th doctor is jacked

I recently re-watched the 1996 Doctor Who TV movie and I simply cannot stop thinking about how the Eighth Doctor physically breaks down the morgue door to escape. And not like, some flimsy little swing door. No. This man bursts out of what is clearly a walk-in industrial freezer door, barefoot and freshly regenerated.

So I did a little digging (and math. there was math. I suffered) to figure out just how insanely strong that makes him.

That morgue door?

Based on visual cues and standard industrial build, here are approximate specs (not exact, but close enough to be unhinged):

Material: Steel plate

Thickness: 4 inches

Width: 3 feet

Height: 8 feet

Weight: ~3,920 pounds

Hinges: Triple concealed

That’s nearly 2 tons of “absolutely not something you open with your squishy mortal hands,” and the Doctor didn’t just open it—he launched himself through it like a Renaissance ghost with a personal vendetta.

And here’s the kicker: he dented it.

Not just broke the hinges, not just forced it open—he left multiple visible dents in solid steel with his bare fists. Even if we’re being generous and the hinges were weak, that door still looks like it lost a fistfight with a Victorian poet.

Industrial freezer doors like this are:

Built from dense, insulated steel

Often vacuum-sealed or magnetically locked

Designed to resist internal pressure

Not meant to be defeated by dramatic amnesiacs in bedsheets

To bust through one, you'd need to overcome:

The inertia of nearly 2 tons of reinforced steel

The resistance of triple concealed hinges

Possible vacuum seals or latch locks

Basic Newtonian laws

And apply enough impact force to deform cold-forged steel

Conservative estimate: Even assuming the door wasn’t locked and only held shut by weight and seal pressure, you'd still need thousands of Newtons of force—possibly several hundred pounds of pressure per square inch—just to budge it, let alone dent it.

That’s enough to:

Body-check a cast iron stove through drywall

Bench-press a baby elephant

Leave knuckle-shaped regrets in steel plating

Give Optimus Prime second thoughts

Physically intimidate a forklift

Get banned from IKEA for structural damage

And the Doctor does it:

Shoeless

Shirtless

Fresh from being legally dead

Wearing nothing but a sheet

In a morgue

In San Francisco

In December

In the movie, he claims he's “half human on [his] mother’s side,” which… okay, sure. Let’s split the difference and say he did all this with 50% human squish strength and 50% alien dramatics.

The Eighth Doctor woke up with no memories, no sonic, no clue what year it is—and still broke out of that freezer, dented a 2-ton steel door with his fists.

Time Lords are built different. Eight is built feral.

Potential DPxDC prompt The Justice League investigates the detonation of a covert government laboratory that whistleblowers warned officials about, speaking of human experiments and the torture and execution of nonhuman entities. Thanks to Superman, they discover some lower levels aren't completely caved in. With Martian Manhunter, they could begin to investigate in person if there were any survivors as they worked on creating a physical passageway for everyone else. J'onn discovers room after room of executed subjects and puddled remains of likely were former subjects. All except one room. In that room remained some creature that seemed partly human, but left partly liquid by whatever they injected into the subject that killed the rest. The subject was alive, but only just. With the one confirmed survivor, the tunnel into the facility sped up and information on how to stabilize the subject found in one of the intact computers. The government agency, thankfully, trusted in the explosion to destroy this information rather than a proper data wipe. The fact that the drug needed was named "Ecto-Dejecto" was disturbing, but it did work to cause the half human, half unknown entity to stabilize into something beyond a non-Newtonian liquid. Now the question was if they'd manage to wake up and inform them of just what this "G.I.W." were about.

And to think people here are still claiming that Kamala would have been just as bad as Trump.

It's a laughable assertion.

I suspect those people are socialists/communist who think that since neither of the candidates are socialists, they're both equally bad. But that's a fallacy.

To use an analogy from physics: Both Newtonian and Aristotilian physics are worse than modern physics at describing observations, but Aristotilian physics is a lot worse than Newtonian physics.
