The Loop

In my previous article I described how one can use a differential equation to calculate the trajectory of the Earth around the Sun. But at the end it was quite tedious so I decided to use a computer instead. Because they are good at repeating things. One way to make a computer do the same […]

Differentialligninger

Det handler om at udregne svære problemer ved at tage det i små bidder ad gangen. Lad mig illustrere det med et eksempel. Forestil dig, at du gerne vil udregne jordens bane rundt om solen. Den her tegning den viser hvordan jorden roterer rundt om solen. Nu vil jeg gerne forklare hvordan det virker. Afstanden […]
