Mandelbrot details
This is a collection of several details of the Mandelbrot set. The images are made in #MATLAB. The same pictures can be made by using an APP, for example #FraXplorer.

Floating Point Error
Переглядів 1283 роки тому
I show how to calculate the error of the representation of a fraction in Python. The result of 1 divided by 3 is not stored exactly as 1/3, but as a fraction N/2^54. In this video I show you how to use the Python-command as_integer_ratio() to find N and 2^54. We compute the error in the representation of 1/3 as 1/3-N/2^54. In numerics, we should always be aware when we are finding difference of...

This video is about FraXplorer which is is available on App Store: apps.apple.com/no/app/fraxplorer/id1471062379 The app makes you zoom into the famous Mandelbrot set.
Saturn V launch
Переглядів 456 років тому
The video shows a simulation of a launch of a Saturn V rocket. The path is not the original but quite close. A simple atmospheric model is used. The implementation use Runge-Kutta-Fehlberg with a low tolerance. The calculations in simulation are done in "real time". One second in the movie coresponds to 10 minutes.
Moon Earth orbit

This movie shows a simulation of the Moon and Earth orbiting their centre of mass. The calculation is done in realtime by using the Runge-Kutta-Fehlberg-5.4 method. The method is implemented in Python.

I started to film when I saw these swans. But I was not aware that I should capture this wonder of nature.
Triple integrals
Переглядів 1,4 тис.11 років тому
This demonstrator shows my program for illustrating triple integrals. I wrote this in JAVA by using the JOGL OpenGL API. It was written for use in my lectures.
A good presentation. I wonder if the problem is in the Python code or that the code exposes something in the architecture (hardware). Thanks for posting the video.
I am first to comment on a seven year old video, huh
this pops up on my recommendation, weird
@@HosheaManein Popped up in mine today too..weird. I just took Calc 3 so maybe thats why?
My program QuasiTiler did not work after I uploaded a new OPENGL-version. At last, I had time to fix the problem and it works fine. The movie shows a QuasiCrystal model that I will work on in the close future.
A few days ago, I saw that these swans with cygnets in their nest.
