Comment Re:VERY interesting study in linguistics (Score 1) 31

Apparently, this is what happened with the Nicaraguan Sign Language, one of the latest natural languages to have appeared (on Earth).

Deaf people in Nicaragua used to communicate with hearing relatives using ad-hoc signing. Once the Sandinist revolution increased the schooling of deaf kids in the late 70s, all of these signing schemes surfaced at Nicaraguan schools, and little deaf kids, well, fixed them, and in the process created a real language.

It doesn't need to be all driven by dishonesty. There may be also the sheer intellectual interest in knowing what follows from a body of doctrine once you add an extra ingredient. It's surely idle -for non-believers, I mean- but it may be an honest piece of harmless fun.

Well, I teach an undergraduate course and avoid using presentation software -which, anyway, would have been Lyx plus Beamer for me-, for largely the kind of reasons advanced in TFA. Most of my colleagues use PowerPoint or something similar this days.

And I'm starting to notice that many students actually prefer the PP-teachers. They want to have the information delivered in formulaic pills, "Concept A stands for blah; Concept B stands for bleh", and this is more easily achieved if the formulae in question are neatly projected on the screen. I could achieve the same effect by dictating, of course, but that's even more boring and less empowering for students that PowerPoint.

It is one thing to establish that some statement is true -i. e., getting to know it-; it is another thing to prove it true, if proving involves something like perfect certainty. Knowledge does not entail certainty, thinking otherwise is simply bad epistemology.

So you may be right that science cannot prove statements right (I do not wish to advance judgement about this), but this is still compatible with science being in the business of securing truths, attaining knowledge about the world.

> The worst, that could happen for a physicist, would be that the observations could be explained with GR.

This kind of (extremely common) remarks strike me as frivolous. It is one thing to say that physicists enjoy being disproved, because this shows the length of the road ahead; it is another thing to say that physicists would hate to attain knowledge in one particular area or other. Science is in the business of securing truths, not in the business of idly advancing ever-refutable theories.
