Let me be more specific: when you allow yourself to be wrong and are capable of admitting that you are wrong that's when learning happens. It's possible that Tach still believes he's never lost an argument (as daft as that premise is)
No, I simply pointed out that it makes no sense for you to keep bringing up the debate since you amply demonstrated that you had no clue on the subject regarding the Doppler effect and that you still don't since you are still under the severe delusion that you won that debate, otherwise you would not keep referring to your utter debacle, that's all.
The damn searching function seems to be flaky, but dig up the thread (the original public debate AND the subsequent thread started by me on matte wheels) and we can discuss if you sincerely continue to believe that you were right on that subject. (?!!???!)
The only purpose would be to further expose your inability to comprehend a fairly simple subject. You lost that debate once, this is enough.
