### Re: The List

I was looking through some science-game related stuff, and found this: https://hackpad.com/Science-based-games-J0X4MSberlM Most TTG games are on there, but there are some quite interesting games I've noticed too. For example, Parable of the Polygons , described as being about •social diversity, raci...

### Re: So I tried to see if I could do something like GSim in J

I could definitely add flinging, but I don't know how I would predict the trajectory. Andy's sim works by essentially fixing the objects for the time being, and computing the results of forces on the new object. A simple O(n) solution, but it doesn't take into account any motion and the effect of a...

### Re: So I tried to see if I could do something like GSim in J

Awesome that you coded it from scratch! You could totally add some simple additions to this (ex. Fling, set speed, move camera, etc) easily. If anyone wants to see what happens to the setup later, just put this into your console: var i; i = 0; while(i<4) { planets[i].vx *= 10; planets[i].vy *= 10; p...

Since we're at TTG, I thought you might like to know tomorrow is the aphelion of Earth's orbit! It'll happen at 19:40 UTC , which means 12:40 PDT (Pacific Daylight), 1:40 PM MDT (Mountain Daylight), 2:40 PM CDT (Central Daylight), and 3:40 PM EDT (Eastern Daylight). At this point the Earth is farthe...

### Re: So I experimented with Ray Casting

Not 100% from scratch, because I went somewhere to find out how to remove the fish-eye effect from my first attempt. For some reason, if you use the actual-distance from the camera to the wall, it produces a fish-eye effect. The best way to prevent this is treat the point on the wall that was hit b...

### Re: TAU DAY

I nearly forgot about tau day today! It should still be 6/28 in a few timezones (mine included).

Uh... Random tau fact I guess. The Feynman point is one 9 longer in tau than in pi.

### Re: Orbiting the known Universe

I just typed it into Wolfram. It gives 7*10^8 m/s, or 2.3c, which matches Neal's answer. You can't save this result by claiming a non-point-mass, because of the shell theorem . Of course, the OU's Schwarzchild radius is 530 billion ly, so... (Something doesn't make sense. I can certainly escape the...
