A Fun Little Differential Equation In Python (Dark Matter)

Check out my course on UDEMY: learn the skills you need for coding in STEM:

One of my favorite classes during my astrophysics career was grad-lvl “computational astrophysics” that I took as an undergrad. We wrote our own solvers for Friedmann equations and lots of other beautiful equations.

We also wrote our own implementations of numerical solver methods but then used the scipy methods as a test.

I had so much fun in that class.

Thanks for posting this!! this is awesome. You've got a natural talent for explaining complicated systems.

As a suggestion, you could make a partial differential equation (PDE) case and creat 3d graphics

Pro tip: genuine Jupyter will take only a tiny fraction of the system resources of the hulking behemoth that is VScode.

Great video again! Can you prepare a video that teaches us how to solve general relativistic differential equation for mercury perihelion problem using python? This equation confuses my mind :(

GUYS !! I FREAKING DID IT !!
I FINISHED THIS ENTIRE SERIE OF 33 VIDEOS THROUGH THAT PAST SEMESTER !
IT HELPED ME A LOT TO GET MY HEAD AROUND PHYSICS PROBLEMS USING PYTHON EVEN IF I DIDN'T ALWAYS UNDERSTAND EVERYTHING. I HAVE TO SAY THAT YOU ARE A BIG TIME BOSS Mr.P ! I THANK YOU VERY MUCH FOR THE KNOWLEDGE YOU GAVE ME ALONG WITH YOUR RAP INTRODUCTIONS. YOU DO A GREAT JOB WITH THIS CHANNEL. I'M GONNA TRY TO DO THE OTHER SERIES NOW.
ANYWAYS, I BECAME A LITTLE MORE SHREGORY...THANK YOU !

woww, you gained a subscriber!
Will look at your content daily, it’s awesome!
Python + Space, can’t ask for more
Keep it up!

This is great! Worked examples are really useful.

[andrewiglinski]

Bud you moved into vscode?! I'm proud of you.

[CoDFOTIS]

That's amazing! What happens though when we have to deal with PDE's that cannot be solved analytically? I hope in one of the following videos you will provide us with a worked example of a similar type of problem where you will solve PDEs numerically for instance with the newton-raphson approach. Keep up the fantastic content, your channel's a gem!

F loving you mate, super cool, one of the best here, will yu do c++ too?
or some cfd?

[sylwek]

Me: Makes sense.
You: How?
Me: Don't know.

When you defined f(x, m) it looks like you used 63 in the denominator but 64 shows up in the denominator of the markdown. Which one is right?

[banditadas]

Hi, I have doubt if we have a vaiable which changes periodically with time how do u pass it and solve the differntial equation, can u please reply, i really need some suggestion

[henryodonnell]

I was wondering, how do you get latex format as output in notebook?

[HYPERLOG]

Ok I'm a dumdum, can someone please tell me where those unspecified functions came from or how they were derived?
