Re: Air Trajectory B/C

At the incipient stage - I came to this forum (not this specific thread) with one question. There was no emotion attached to it. Just a fact-based question. In response I got several emotion-loaded responses here and a few were nasty. Since then - my initial question got answered, with logic, at the...

Re: Air Trajectory B/C

RE your comment . . " It's a shame you don't want your children to participate in this "dumbed down" competition." I did not say anything to indicate I don't want my children to "participate." Looks like we have word-connotation-problems here again. I stated that my last child is home-schooled. That...

Re: Air Trajectory B/C

No offense intended here but it sounds kind of silly to me. If real science in the real world had to limit itself to these two two factors you listed - hardly anything would get done. It sounds like part of the equation is dumbing things down so all can participate. This kind of thinking reminds me ...

Re: Rules contradiction?

This sort of reply from Mr. "Retired 1" helps make a mockery of what is supposed to be a science-based event. "Your constant carping about this is not going to win friends or influence the rules committee. The rules are not going to change to placate you. You have to comply with the existing rules o...

Re: Air Trajectory B/C

I see a lot of talk about ping-pong balls and PVC pipe. I don't see anyone stating what sort of PVC pipe or what sort of ping-pong ball. Maybe I missed it somewhere in these discussions? PVC does not have just one ID. It is the OD that is the constant. So, "1 1/2" PVC is always 1.9" on the outside d...

Re: Rules contradiction?

Still looks like a distinct contradiction to me . I have submitting the following question to the official rules clarification area twice now. Once on Jan 21 and once today Jan 27. No answer posted so far. This is what I asked. 3d states an 80cm cube may be used at "any orientation." This is not pos...

Re: Rules contradiction?

A few more comments from me (John Demarrais) I stated . . "The written rules clearly state (with a bit or paraphrasing) that an 80 cm square can be used "in any orientation chosen by the team."". I got a reply stating . . "This is NOT what the rules say. The device must fit in an imaginary cube that...

Re: Rules contradiction?

One more comment. RE the "PostScript" pointed in my direction that states . . "P.S. - please don't convert / reference imperial units when the rules specify metric. Metric is the defacto system for SO (and much of science and engineering in general) and by using it you will become more familiar with...

Re: Rules contradiction?

I am 65 years old and was told in grammar school that the US was going to change over to the metric system in the 60s. As we all know - it never happened. I was working as an auto mechanic when the first US cars appeared with a mix of SAE, USS, and metric hardware and it caused a lot of confusion. F...

Re: Rules contradiction?

How is that NOT a contradiction? The written rules clearly state the device can be the max size of a cube with 32.4" sides (80 cms). The written rules also clearly state the operator of the "device" can orientate it any way she or he chooses. If "orientate" does not mean to move to any angle wanted,...
