Now normally I'd be delighted that someone was making a film set in the Fifth Century at least, one that wasn't another fantasy about "King Arthur" anyway. After all, it's not like there's a shortage of remarkable stories to tell from that turbulent and interesting time.
And normally I'd be even more delighted that they are actually bothering to make it look like the Fifth Century, rather than assuming because it's set in the Roman Empire everyone needs to be wearing togas, forward combed haircuts and lorica segmentata.
And I would be especially delighted that they are not only doing both these things but also casting Rachel Weisz in the lead role, since she's an excellent actress and, let's face it, pretty cute.
So why am I not delighted? Because Amenabar has chosen to write and direct a film about the philosopher Hypatia and perpetuate some hoary Enlightenment myths by turning it into a morality tale about science vs fundamentalism. As an atheist, I'm clearly no fan of fundamentalism - even the year old variety though modern manifestations tend to be the ones to watch out for.
And as an amateur historian of science I'm more than happy with the idea of a film that gets across the idea that, yes, there was a tradition of scientific thinking before Newton and Galileo. But Amenabar has taken the actually, fascinating story of what was going on in Alexandria in Hypatia's time and turned it into a cartoon, distorting history in the process.
From the press release timed to coincide with the film's screening at Cannes this week: Played by Oscar-winning British actress Weisz, Hypatia is persecuted in the film for her science that challenges the Christians' faith, as much as for her status as an influential woman.
From bloody clashes to public stonings and massacres, the city descends into inter-religious strife, and the victorious Christians turn their back on the rich scientific legacy of antiquity, defended by Hypatia. So we are being served up the idea that Hypatia was persecuted and, I'll assume, killed because "her science And why have a movie with one historical myth in it when you can have two: At least he's done his homework enough to realise that the decline of the Great Library was a long, slow deterioration and not a single catastrophic event.
But he still clings to Gibbon's myth that a Christian mob was somehow responsible. And rather niftily invents a "second library of Alexandria" so he can do so. Of course, there's an inevitable moral to all this: The director also said he saw the film worked as a parable on the crisis of Western civilisation.
We are talking about social crisis, economic of course, this year, and cultural. We know that something is going to change -- we don't know exactly what or how, but we know that something is coming to an end.
And who are the murderous fundamentalists? I suspect the answer could be "Muslims". The LA Times article on the Cannes screening seemed to think so: The film is at its most compelling when Amenabar shows the once-stable civilization of Alexandria being overwhelmed by fanaticism, perhaps because the bearded, black-robe clad Christian zealots who sack the library and take over the city bear an uncanny resemblance to the ayatollahs and Taliban of today.
However far you want to take Amenabar's parable, the outlines are clear - Hypatia was a rationalist and a scientist, she was killed by fundamentalists who were threatened by knowledge and science and this ushered in a Dark Age.
Hypatia the Myth Not that there is anything very new or original about this - Hypatia has long been pressed into service as a martyr for science by those with agendas that have nothing to do with the accurate presentation of history. As Maria Dzielska has detailed in her study of Hypatia in history and myth, Hypatia of Alexandriavirtually every age since her death that has heard her story has appropriated it and forced it to serve some polemical purpose.
Ask who Hypatia was and you will probably be told "She was that beautiful young pagan philosopher who was torn to pieces by monks or, more generally, by Christians in Alexandria in ".
This pat answer would be based not on ancient sources, but on a mass of belletristic and historical literature Most of these works represent Hypatia as an innocent victim of the fanaticism of nascent Christianity, and her murder as marking the banishment of freedom of inquiry along with the Greek gods.
I still have a soft spot both for Sagan and Cosmos, since - as with a lot of young people of the time - it awakened my love not only of science, but a humanist tradition of science and a historical perspective on the subject that made it far more accessible to me than dry formulae.
But popularisations of any subject can create erroneous impressions even when the writer is very sure of his material.
And while Sagan was usually on very solid ground with his science, his history could be distinctly shaky.Recall that a parabola is the graph representing a quadratic equation, which is standard form is as follows: y = ax 2 + bx + c.
where the value of 'a' determines whether the parabola opens upwards of downwards (i.e., the parabola opens upwards if a>0 and opens downwards if a/5. Page I A HISTORY OF THE INTELLECTUAL DEVELOPMENT OF EUROP E.

, no rule of evidence, no standard of belief. But the downfall of such a system was inevitable as soon as men . Write the equation of the parabola 2x 2 + 8x + y + 3 = 0 in standard form to determine its vertex and in which direction it opens. Write the equation of the parabola 3 y 2 – 12 y – x + 9 = 0 in standard form to determine its vertex and in which direction it opens.
For parabolas that open either up or down, the standard form equation is (x - h)^2 = 4p(y - k). For parabolas that open sideways, the standard form equation is (y - k)^2 = 4p(x - h).
They are essentially the same except that the x and y are switched. Notice also that the h is always with the x and the k is always with the y. One way you can remember this is .
