Which of the following are true about Hypatia, based on
readings and classroom activities?
1.
Theon of Alexandria's commentary on the third (book) of
the Mathematical syntaxis of Ptolemy begins with, "the
edition having been prepared [paranagnostheisa] by
the philosopher, my daughter Hypatia."
Knorr thought that Rome did not find conclusive stylistic
variations because the literal translation of
[paranagnostheisa] is "reading along" instead of
"prepared". He found the same term used for Eutocius'
commentary on Archimedes, and compared this to a
second Archimedes version. Eutocius had aded new
paragraphs, and modified others, but the text was
mostly unaltered. So, Knorr looked for sections of Book
III distinct from the rest of the commentary and from the
other Books, and found a section on sexigesimals that
he attributes to Hypatia. in Book I, a sexigesimal
computation was done very differently than in Book III -
instead of using a chart, a method of long division for
sexagesimals was used to find successive quotients
by trial one digit at a time. The answer found was an
approximation, as opposed to the precise answer
found in Book III by the table method.
2.
In the 10th century Suda Lexicon, it said that "She
(Hypatia) wrote a commentary on Diophantus, the
Canon of Astronomy, a commentary on the conics of
Apollonius, and Archimedes Dimension of the Circle".
3.
There is no historical evidence that Hypatia worked on
Archimedes Dimension of the Circle, but it is
interesting to speculate. Knorr finds stylistic
similarities in Archimdes Dimension of the Circle that
he the attributes to Hypatia.
4.
We know that Hypatia was a mathematician, but we
don't know for certain exactly what she worked on.
5.
In Archimedes dimension of the circle proof, they did
know the area of a right triangle, but not of a circle.
6.
As the number of sides gets large, the area of a
polygon inscribed in a circle
does not approach the area of the circle.
7.
If B and C are adjacent vertices (forming an
edge) of a polygon inscribed in a circle with center A,
then BC is less than the length of the arc of the circle
corresponding the angle BAC
because the shortest distance between two points
(in Euclidean geometry) is a line.
8.
If B and C are adjacent vertices (forming an
edge) of a polygon inscribed in a circle with center A,
and K is the midpoint of BC, then AK is perpendicular to
BC because of the setup and SSS.
9.
Grinstein's (light blue) book is a good, reputable
resource on Hypatia, but Osen's (green) book is not
since it quotes Hypatia's words (which we don't have),
and gives other misleading information based on a
paper that was a fictional account of Hypatia.
