About Cavities

When food we eat sticks to our teeth it makes a place for germs to work. The food turns bad, and the germs multiply and make holes in our teeth, which we call cavities. The surface of our teeth is made of enamel and is the hardest substance in our body. Beneath it is a layer of dentin. Inside that is the dental pulp, which contains blood vessels and nerves. When teeth start to decay and the material they are made of wears away, it affects that dental pulp and results in toothache. Cavities are cause when particles of food left in the mouth after eating begin to decay. This produces acid which eats tooth enamel. We should always brush our teeth right after eating. But if we should happen to get a cavity anyway, then we should go to the dentist right away. If we don't our teeth will become worse and worse and may have to be pulled if they're too bad.

Earth sea my view

I love the books, so I am keeping my expectations low! For starters, I am not convinced that doing the first two books as a 4-hour miniseries really makes any sense from a time/drama standpoint... And the screenwriter, Gavin Scott, definitely only got it half right with his adaptation of The Mists of Avalon.

And as I predicted, they chose a white guy for Ged/Sparrowhawk (Shawn Ashmore - Iceman in the X-Men films and the instant-clone freak of the week on Smallville), though at least the old wizard Ogion is the right color for a Gontishman (Danny Glover). Kristin "Lana" Kreuk as Tenar might be okay - she is a little older than in the book, but she is certainly got the petulant little bitch thing and concerned/conflicted expression down... And Isabella Rossellini as the priestess that, well, it seems like she is *always* in these Roberts Halmi-produced literary miniseries!

Since Earth sea itself is decidedly pre-industrial, and the focus is mostly on simple settings (even the wizard academy at Roke is very low key compared to, say, Hogwarts), I am not worried about the look being wrong. And let's face it; the effects required are also pretty easy by modern standards. But I truly fear that the adaptation will miss what makes the Earth sea books special: the language, the philosophy, the sense of wonder and yet familiarity.

Though written in very plain language and seemingly very simply plotted the earlier Earth Sea books deal with some complex real-life issues (self-knowledge, restraint, balance, the value of seemingly alien and evil people, etc.) I am afraid that the miniseries will put too much effort into making the dragons believable, and not enough into the really underlying messages, the heart of the story.

Death of a star

The stages in the evolution of a star are very complicated. All stars begin as gaseous pillows in a region of space called nebulae. Stars form in this nebulae when these gaseous materials come together to make a star that goes from 450 times smaller than the sun, a proto star, to 1000 times larger than the sun, a massive star. When the proto star starts to shine it is a sign that it is going through nuclear fusion, when hydrogen becomes helium.

When the star becomes too hot, the helium turns to carbon and the star starts to expand and becomes a red giant. The red giant starts to breakdown, which then turns into a planetary nebula. The core of the star is called a white dwarf until it dies and stops shining, then it is called a black dwarf.

The other kind of star called is a massive star, when a star is made with less hydrogen. As the massive star starts to lose hydrogen, it expands and becomes a super red giant. When this star explodes, the gases released called are supernovas. If the beginning star called was a massive, star the supernova turns into a neutron star, one smallest kind of stars. If the beginning star was a giant star then the supernova turns into a black hole. The stages of a star all depend on chance.

Universe Views

We know our biological limitations because we have come up with some devises which have the grater capabilities than our senses. This is still not true with math and physics. These two are just developed based on human brain's ability to interpret the natural phenomena. Till date we do not have any machine which can over perform the human brain in math and physics(someday artificial intelligence might do that), so there is really no way to judge whether the math or physics we do is correct or not. Our math and physics are based on certain unproved assumptions which are based on the way human brain interprets these phenomena, so we cannot be 100% sure that the math and physics we do is correct or not
