| 535361 | 2007-03-27 11:37:00 | :lol: I don't think anyone's ever going to use anywhere near 65,000 rows either. I think it's just a "because we can and it makes us look better than Microsoft" thing. Of course, then, since Corel isn't Microsoft, they are better anyway. :D |

| 535363 | 2007-03-28 05:07:00 | Wow!! All this maths stuff. It's coming back now. Glad I am retired and have forgotten lots of it. But it is absorbing and satisfying. I always fancied the duo decimal stuff (base 12) - perhaps somebody can enlighten me. Our instructor 50 years ago reckoned pi would work out. I admit I told my students that I believed that was true but I never checked it. Has anybody else? Messing about with maths to be honest I still find to be satisfying and rewarding. But I hate these private school people who insist that they can make learning maths fun. It isn't, it's hard work and can be terribly boring. But what a reward when it is learned. I specialised for a while calculating deflections in aircraft rigs etc. Greatly satisfying when things worked out to my calculations. But it took me hours and hours of study for years to reach that point. Tom |

It doesn't matter what base you use, you can't represent it in a finite number of digits unless the base is itself a multiple of Pi, which would make nearly everything else unrepresentable :) . Whether or not any particular activity is fun is entirely subjective - a good school may well increase the proportion who enjoy a particular subject. | TGoddard (7263) | ||
