![]() A difference of just 0.0002 in the barometric pressures caused huge changes in the final results.Įdward Lorenz: “Chaos: When the present determines the future, but the approximate present does not approximately determine the future.” - quoted from hereĪ second thing that Silver writes about is a European weather model. Eventually they tracked it down to the setting of barometric pressure in one area of the grid where the floating point number was being rounded differently. They spent quite a while trying to figure out what the problem was. ![]() According to Silver sometimes the forecast would be clear skies over Kansas and sometimes thunderstorms. This was when running through the exact same code using what they thought was the exact same data. When Lorenz was working on a weather forecasting program on a computer they were getting widely divergent results. He writes about Edward Lorenz, the man who coined the term “butterfly effect”. Chaos theory is where very small differences in the starting conditions of a dynamic system can result in completely different final results. So happy save money to GBC fans.I have been reading Nate Silver's The Signal and the Noise and in one of his chapters he discusses weather forecasting and chaos theory. The great differente is that LEGO's are mate and China's are "shine"Īnyway, It is always interesting get 30 balls for trying with genuine lego balls your modules in case you go to an event The only problem is that hole could be read as "black". not much but it could interfere with color sensor. no so much dfference because they are so small. these are simple "beads" for aesthetic purposes. I suppose this is because the moulding quality. I have noted some balls have little less diameter than LEGO's (no more than 0.3 mm measured with caliper), but when they move I haven´t noticed any difference. Many thanks for all your help! You saved me a large investment, that is for sure.ĮDIT: I just saw my profile on the left. I am color sensing, how close is the color of the orange one to the basketball? What about the small hole, does that impact rolling? ![]() do they all fit within 2 studs and roll nicely? IMPORTANT: How are the moulding tolerances? i.e. Oh wow, found the exact ones you mentioned in your blog post!Īvailable in many colors! I suppose I shall buy orange and white )īefore I buy, I have a few questions about them.ĭoes the weight difference play any part in their performance? I suppose for about 5 euros you can have a large bunch of it on ebay. too much for a single user, even for a community ^^ :)Īnyway I asked some moulding companies for a large quantity but it only worths when you buy more than 100000 balls. with many prices, You could have more different if you search "14 mm Round Beads". If you search "Round Smooth Plastic Beads 14mm" you have many stores and types to choose. ![]() I have not posted any link of stores because of i have found it in ebay, and I don't know about stores policies on Eurobricks. I supported the cuusoo project, but as I said before, I have serious doubts about the feasibility of it succeeding, especially when you look at what lego is looking for - set ideas, not parts pack.Ī better bet would be a 'GBC starter module' or something like that. However, I didn't see in your blog any link to where I can buy some. Well, I certainly have more of an open mind about using other ball alternatives. Showing our modules in events we'll show to the world hoy fun GBC is! I believe we could be 10000 fans of GBC, builders or just "viewers" I have to say that balls are almost the same except that they are finest polished and they may have more tolerancy than LEGO balls. The cheapest way to find is that that I proposed time ago (In 3 languages, english at the end)īut I think the best way is support it by cuusoo. Yeah, I came with this problem of lack of balls when i first started to build my modules.
