explains both the old data and the new data. For a simple example
'The angles of a triangle add up to 180 degrees.' You can draw
millions of triangles for which that is true. With a tennis ball
and a biro you can draw one triangle which shows it isn't true.
Start at any point, draw a quarter of the way round the ball,
turn the ball at rightnagles to the line and draw a quarter round
again, turn again at rightangles in the same sense and draw a
quarter way round again. You'll meet the original line at
rightangles. You now have a triangle the angles if which add up
to 270 degrees. It is also. incidentally, [possible on another
common object to draw a triangle the angles of which add up to
les than 180 degrees. The way out is to define triangles in such
a way that all three situations become 'true'. That realisation
was known to Euclid himself but he couldn't work on all cases. So
he chose
Simple for the other case, just cut the ball and draw the triangle
"inside". Don't remember the exact angles but they are less than
180 summed.

******************************************************

The three angles of a triangle only add up to 180 degrees in the
case of a two dimensional or PLANE triangle.

A triangle drawn on a tennis ball or the earths surface is THREE
dimensional and SPHERICAL TRIGONOMETRY applies.

It may have 3 angles each of 180 degrees, total = 540!

You beat me to that. Interesting illustration that Moody doesn't
know quite as much as he thinks he does.

And that is an even better illustration of how incompetent at
argument you are. Toddle off and get yourself educated in
understanding English. I said very clearly that it only needs ONE
example to falsify a proposition so I gave only ONE in full, albeit
did refer to there being others. That ONE proved the case. There was
no need for detail any more. It doesn't matter how many more I do
or don't know, ONE is enough.

If it had been necessary to give two examples, the easiest to
demonstrate in practice would be the 'outside' of a trumpet - with
the warning that any trumpeter who lent you his instrument for the
demo would want it back polished afterwards. And if you want to be
further picky 'outside' is in inverted commas because that is the
normal.inaccurate, non-mathematical usage. There is no inside or
outside in a hollow tubular object of any shape, and that includes
the human digestive system.

It's usually not a good idea to try to get clever with a research
organic
chemist on the subject of shapes and their deformations. Everything we
do is based on understanding shapes, and how they fit or don't fit in
three dimensions, and how they deform during reactions; and what we
deal with is vastly too small to be seen. It follows that organic
chemistry has to be imagined in 3D in the head before a finger is laid
on glassware. Next time you pop a pill for some condition you will be
benefitting from at least one organic chemist's 3D thinking about
shapes. It's not unique to organic chemists. Some kinds of sculpting
and engineering can't be done without the same ability to 'see' in 3D
what doesn't yet exist,. for just two examples. A third, and
genealogically interesting case is that one particular kind of
dyslexia is
accompanied by an ability ro 'see' in 3D which is orders of magnitude
greater than most organic chemists I ever knew in the drug research
game. The tendency to that kind of dyslexia appears to be inheritable.
Find yourself an illiterate hefty bloke who is brilliant at dry-stone
walling, and you'll probably have found such a dyslexic. And a little
enquiry round his family will probably reveal more of them. They'll be
in trades where the ability to read and write doesn't matter but the
ability to 'see' in 3D what doesn't yet exist is the foundation of the
trade. They will all appear 'dim' to orthodox educators and inevitably
fail written examinations. No doubt some have low IQ but the
distribution of IQ is believed to be much the same as the non-dyslexic
population albeit the dyslexic can't do written IQ tests. Some are
exceedingly bright, but must can't express it in writing. One in my
year at school, a very selective grammar, managed to get right through
to the Fifth without being able to read properly. She could remember
anything spoken to her at just one 'take'. That included whole
Shakespeare plays. That she was a bloody good actress also depended in
part of her knowing exactly where she and everybody and everything
else was on stage from moment to moment. In due course she became a
DBE for her acting. She had dyslexic relatives.
