From article above I interest in the proses discover the non
Euclidean geometry. Gauss who coined the term "the
non-euclidean geometry". He refers to his own
work that today we call hyperbolic geometry
.. Some modern
writers are still
considered "non-euclidean geometry" and "hyperbolic geometry"
to be synonymous. In 1871, Felix Klein,
by adapting the metric
discussed by Arthur
Cayley in 1852, was
able to bring nature into a location metric
projective and therefore is able to unify the treatment
of hyperbolic geometry, euclidean and elliptic
under the umbrella of projective geometry.

I think this draft still inconsistent with the aim of
education in Indonesia. So it is good if government want to revise that
curriculum. However this curriculum challenge the teacher to build their
creativity in the teaching learning proses.

I think science
has no boundaries. it's just that every matunia have in understanding the limits
of science. The relationship between the philosophy of science that can be integrated
in the philosophy of science, where the philosophy tries to answer the
questions posed science, shows the limitations of science in explaining the
various phenomena of life.

I have been read Kuhn opinion, then I know that Since he
considered problem solving to be a central element of science, Kuhn saw that
for a new candidate for paradigm to be accepted by a scientific community,
"First, the new candidate must seem to resolve some outstanding and
generally recognized problem that can be met in no other way. Second, the new
paradigm must promise to preserve a relatively large part of the concrete
problem solving activity that has accrued to science through its predecessors."
And overall Kuhn maintained that the new paradigm must also solve more problems
than its predecessor, which therefore entailed that the number of newly solved
problems must be greater than those solved in the old paradigm.
