Algodoo

Nicely done! Did you use any of Maxwell's equations in your calculations? Just curious.

Just one note about the in-scene instructions. #3 says to use the Move Tool, but the Move Tool is not available while the scene is running in "Play Mode". It would need to be stopped, move the circles, and then start the scene again. Other than that detail, it works great, and is quite interesting!

Q: Did you use any of Maxwell's equations in your calculations?
A: No, I don't understand Maxwell's equations.

I started with the standard equation for the magnetic field around a long straight wire and modeled 2 wires. I took the sine of the result in order to get bands. I then tried to linearize the result by using the natural log function. I then noticed you can't take a log of a negative number so I tried absolute values, but that didn't look right. I then tried multiplying and dividing the distances and that's where I ended up.

I other words, I played with equations until I ended up with something that looked believable. I think that matto did the same thing but we ended up with different equations.

That's exactly how I do math too! For example, I'm currently playing around with a missile targeting scene. I know the basic equations for finding the trajectory of a missile that are required in order to intercept a moving target, but I don't fully understand HOW they work. And so I am tweaking the calculations and adding "fudge factors" in some areas in order to make them work for my situation. The more I play with them, the more I'm beginning to understand how and why they work. FUN STUFF!

BTW - I don't understand Maxwell's equations either but I do understand how important they are in designing things that use magnetic fields. Maxwell was an incredible genius.

Algodoo is usually very accurate in terms of basic physics. Some things that affect this accuracy are low sim.frequency, air friction, air buoyancy, and contact penetration.

True, Algodoo is certainly an amazing product.

Regarding '#3 says to use the Move Tool, but the Move Tool is not available while the scene is running in "Play Mode".', the drag, move, and cut tools are available when I run Algodoo in play mode. Maybe your settings are different than mine.

I just realized those tools actually ARE available during Play Mode, but in a different position on the screen! I'm so used to selecting tools from the list that shows up on the lower-left side of the screen that I forgot that they also show on the bottom of the screen just to the right of the sim control buttons during Play Mode. So, you can ignore my comment about the Move Tool not being available in Play mode. That was my mistake.

you made a mistake!

Yes, I know it's very difficult for you to believe, JohnG, but it's true.

everyome makes mistakes sometimes

Very beautiful and interesting!
Yes, we played with the equations, but you came up with a better result.
You are a great !!
I am happy to have given you the inspiration.
I would like to ask one thing:
Is there a site, a book to study Thyme?
Thanks !!
