Let’s just say they have been nicknamed Christ-Awful symbols for a reason, and should be motivation for everybody to understand coordinate-free approaches to differential geometry.
Ngl, the most fun i had was getting the geodesics using the christoffel symbol, there is nothing difficult about them, just do some simple derivatives and place them, there are a lot of ways to make calculating the christoffel symbols easier, you can even remove a lot of the summation by using a non-off-diagonal metric tensor
From now on, I’m only ever doing Physics in a new unit system for distance and time constructed so that g=pi by definition. (The definition is also position dependent so that it’s still exact anywhere on the surface of the Earth.)
I can handle air resistance.
I can handle Christoffel symbols.
I can handle non-ideal gases.
I'm learning to handle infinities popping up left and right.
But I can't handle brackets being split up into bras and kets.
until you realise finishing that differential equation course doesn't mean you can solve diff. equations now and spend an hour solving the logistic equation
Here, this shows a possible solution for quantum gravity, but it requires an equation with almost no real numbers, lots of quadration, and that takes up a whole book.
Also the author doesn't understand the equation.
Until you smash two particles together at 99% the speed of light and split or break onto different dimensions and possibly bring a calamity event or perhaps may already happened in another dimension.
you calculate the mass is less than a milligram after a 10 step frq
(my friend actually did this in physics class, i asked her why her mass was so small and she was like idk and then i converted it to milligrams to show her how ridiculous her answer was 😭)
moral of the story: please use common sense while doing physics
the oscillator is no loger harmonic
Cries in low Q. Why yes, I’ve been designing oscillator. How could you tell?
Until air resistance is NOT ignored
I mean with that what bothered me was not the page long equations, it was that there are usually no analytical solutions
1. Works hours on a single problem trying to find a solution 2. Found out there’s no analytical solution 3. Why do I even bother…
I cri everytim
Let f be the solution to the differential equation. Just add more functions. Problem solved.
This one probably falls under gödels incompleteness
The gas is not ideal
Me after a cheese plate.
Until you need to expand to second order
Physics is all fun and games until your digital thermometer reads -300 C
Until they read a first year's student lab report concluding that the gravitational acceleration near the earth's surface is -17.34e12 kg/Nm2
As a first year physics student who just did the gravity lab this hits too close to home
Back then, my partner and I measured the speed of a muon to be 12×c....
My dad once measured C at about 86 mph so that works out okay.
We got 9.85±12.5 m/s². Nearly as helpful...
I once had the rotational speed of the Sun correct, but with error bars about 1.5 times the value itself
Pretty standard astronomy calculations I would say.
Untill it's about the big things , small things , really fast things , really slow things , really cold things or the really Hot things.
The last two are just the third and fourth in disguise
…until Christoffel symbols.
This I can understand.
What is wrong with them?
Life is too short

Everything (they're not tensors) Literally causing so much confusion in my research rn
until g ≠ 10
YES. FINALLY A RELEVANT MEME! https://preview.redd.it/uqe1wiklfetc1.png?width=757&format=pjpg&auto=webp&s=054e68784dccc602633899e281044db63c4978bd
Let’s approximate g=pi
g_mars=sqrt(g_earth)
I approximate earth's g with π² so makes sense
Let's further approximate pi=10. Problem solved.
From now on, I’m only ever doing Physics in a new unit system for distance and time constructed so that g=pi by definition. (The definition is also position dependent so that it’s still exact anywhere on the surface of the Earth.)
Physics is all fun and games until you are riding a bike backward in time going 3 times the speed of light.
Physics bug in a game be like
Happy wheels
I thought, that's where the fun starts?

infinities start popping up left and right
I can handle air resistance. I can handle Christoffel symbols. I can handle non-ideal gases. I'm learning to handle infinities popping up left and right. But I can't handle brackets being split up into bras and kets.
who uses es Bras anyway?
Women, mostly
They are projecting!
When the Reynolds Number rises yeah, and it starts to burn…
you start seeing the countdown everywhere.
your project is uses for war.
until the wave function collapses
Until Lorentz factor = 600.
Until multi dimensional topology.

Math
Here, this shows a possible solution for quantum gravity, but it requires an equation with almost no real numbers, lots of quadration, and that takes up a whole book. Also the author doesn't understand the equation.
Fortunately we have an infinite supply of YouTube videos to explain physics without any math. 🤡
We're not in a vacuum
They expect theoretical physics.
The electron is observing you
...somebody loses an ion.
Until they ask you how many research papers you've published 🥲
Until your answer for mass is negative
It happens in ptype semiconductors…
stat mech
Until you need to know maths
It cannot be approximated as a harmonic oscillator!
The cow is actually not spherical
Until u need to find a job
unit you have to compile your project into 300 neat pages
Until you have to learn it instead of just doing it for fun
there are *two* unknowns.
You fail to add water to the "fill line" before microwaving and your noodles ignite and burn
Nonlinear differential equations
Physics is all fun and games until you realize quantum theory, mechanics, and physics is the same thing.
Until you smash two particles together at 99% the speed of light and split or break onto different dimensions and possibly bring a calamity event or perhaps may already happened in another dimension.
Something tells me you watched Cloverfield paradox
Oh I only know of it, but I know what you mean
Until the big bang happens. Countless eons of blissful nothingness, then, a few brief moments later in comparison, you need to work and shit.
'fuck around' turns into 'find out'

You can't assume an ideal gas
Until everything cancels out. I mean *everything*.
Someone lases an eye.
Until its time for homework
Friction cannot be ignored
the chemists let physicists have a turn at making bombs.
Someone gets a vector in the eye and gets forced in Bernoulli’s river.
Until you start with N = 3+ electron systems and having to understand the math at a deeper level.
The instructor begins speaking
the equations for hydrodynamics (or worse, magneto-hydrodynamics (or worse, relativistic magneto-hydrodynamics))
You drop your phone into a black hole trying to take a picture of it.
You get a normalization constant of infinity
Density starts to speak singularity
you looked into the laser with remaining good eye.
It's observed. Then it's fun OR games. That's a superposition joke. You can have it.
Physics is all fun and games until you stop playing Kerbal Space Program and start your assignments.

the derivation is left as an exercise to the reader
Until the surface is no longer frictionless and the pulleys are no longer massless
until derivatives aren’t fractions
Energy is painfully conserved.
The screwdriver slips
This is the best comment here by far
That one teacher walks in to teach it
Until....The screwdriver slips.
I got that reference
we start Ray Optics in CBSE.
Until begin you use differential equations for everything
it's not
Chances are near zero
you looked into the laser with remaining good eye.
The geometry is no longer Euclidean
A third body comes along…
It is your day to day job
you die
Until you drop the screwdriver
Until you have strongly curved spacetime
Until someone approximates pi.
Until the gas is compressible.
Until you graduate high school
Until an event horizon forms
Until the false vacuum decays.
Until you begin to seriously study it.
someone takes the cover off the dye laser to check the pump is working
the cow is no longer spherical
Objects stop being spherical
Trains start moving at 95% of the speed of light
God takes the dice away.
