Re: A Nice Mathematical Puzzle

Something like this? My friend in the village did the reverse as my initial answer when he visited my house the other day. Upon returning to the village he calculated (T2-T1)/2 and wrote me a letter stating that time difference. His 'clock' for T1 and T2 being the Church clock. Edit: adjusted for th...

Re: A Nice Mathematical Puzzle

Wind the clock and keep it running, make a note of the current time (T1, say 9am), walk to the village and look at the Church clock, make a note of that time as well (Tc, say 1pm), walk back to your house/clock (assuming that walking both ways takes the same amount of time). Take a note of the curre...

Re: Bouncing Basketball tech demo on the Acorn Electron

I have just tried this on my Electron - although I didn't seriously believe you were making this up, I decided I had to prove to myself that it was really possible... It's really incredible! It doesn't look like something that an Electron can produce at all. =D> That's the biggest compliment I coul...

Please don't think I'm trying to belittle any of your achievements, just explain them in terms I can understand myself.
I wasn't thinking that but I thought you (and anybody else) might appreciate the challenges of getting from idea to execution.

Re: Bouncing Basketball tech demo on the Acorn Electron

... try it on your own Acorn Electron (will NOT work on any emulator) ... That sounds like a challenge - what are the rough edges in emulators that stop this working? One or two things, or many things? From my experience it boils down to timing issues. None of the emulators have 100% accurate timin...

Re: Bouncing Basketball tech demo on the Acorn Electron

Almost correct! The rainbow bar in front of the basketball is where all 4 colours are changed. The rainbow bars behind the basketball is where only one of the four colours is changed. The basketball itself can only use a maximum of 3 colours this way. Right ..... so the colours are "transparent" fo...

Re: Bouncing Basketball tech demo on the Acorn Electron

Am I right in thinking that the actual basketball itself contains only 3 colours; leaving you a fourth palette entry to use for where the "rainbow" lines pass in front of the ball? Or am I going in totally the wrong direction there? Almost correct! The rainbow bar in front of the basketball is wher...

Re: Bouncing Basketball tech demo on the Acorn Electron

It's certainly impressive! The timing of the bounces feels right; I don't know whether you're solving the differential equations on the fly :) or just using a pre-calculated list of positions, but either way it's impressive. By the way, have you ever tried creating graphics on an Amstrad PCW8256 wi...
