Careful measurement data that can be confirmed on the other side of the Earth is basic to science moving ahead. There isn't much room for the use of Cooke's Variable Constant. Otherwise manufacture of better buggy whips would never have happened.🙂
 
If questions needed anti-fool prescreening by, say, an Engineer or similarly qualified person, half or more , including yours of course would disappear from this Forum.

Which would not be a bad idea, air would be much more breathable.

It would be a bad idea. Threads like this do serve a purpose, and it's better that the "fools" learn rather than continuing to be fools.
 
Osvaldo de Banfield,
Why not donate your time other than acting like a fool in DIYAUDIO forums to an organization that saves child lifes, by example.
Boy ,this place is going downhill quick.

Simply because during several years I had donated time, effort and money to my local ham Radio Club Banfield LU1EEE, where I made ham radio LW1DSE in 1987 and teaching and transmitting to newer generations, the passion, enthusiasm of the ham radio; and of trying to make their own ham devices, now more difficult task to do as new people prefeer spenting time in phacebook or doing stupid posts in some forums than enjoying and learning by their owns, although things don't work as one expect.

Did you?
