We've got a 4-month old at home, and I beg to differ. Besides crying, her first sounds were schwa-like "uhhh-guuuh". The schwa is the sound created when the mouth is more or less in a neutral position, so this makes sense to me. Definitely nothing close to "ma" yet. We'll keep you posted.
Black holes can have any mass. Since gravity increases in inverse proportion to volume, any quantity of matter that is sufficiently compressed will become a black hole. However, when black holes form naturally, only a few mass ranges are realistic.
Black holes can be divided into several size categories:
Supermassive black holes that contain millions to billions of times the mass of the sun are believed to exist in the center of most galaxies, including our own Milky Way. They are thought to be responsible for active galactic nuclei.
Intermediate-mass black holes, whose size is measured in thousands of solar masses, may exist.
Intermediate-mass black holes have been proposed as a possible power source for ultra-luminous X ray sources.
Stellar-mass black holes have masses ranging from about 1.5-3.0 solar masses (the Tolman-Oppenheimer-Volkoff limit) to 15 solar masses. These black holes are created by the collapse of individual stars. Stars above about 20 solar masses may collapse to form black holes; the cores of lighter stars form neutron stars or white dwarf stars. In all cases some of the star's material is lost (blown away during the red giant stage for stars that turn into white dwarfs, or lost in a supernova explosion for stars that turn into neutron stars or black holes).
Micro black holes, which have masses at which the effects of quantum mechanics are expected to become very important. This is usually assumed to be near the Planck mass. Alternatively, the term micro black hole or mini black hole may refer to any black hole with mass much less than that of a star. Black holes of this type have been proposed to have formed during the Big Bang (primordial black holes), but no such holes have been detected as of 2007.
Apparently Brin is a fan of Singularity, per this back cover blurb: back cover of Singularity: "DeSmedt veers an action-packed thriller into perilous realms of black hole physics. The combination of adrenaline and intellect sizzles." -- David Brin, Hugo and Nebula award-winning author.
There's an intersting Sci Fi novel that asks "What if the cataclysmic Tunguska explosion of 1908 was caused, not by a meteor or a comet, but by a microscopic black hole?": Singularity by Bill DeSmedt, 2004.

I have a friend who uses Dragon Dictate and a set of Emacs macros to write code. He's been doing this for over 10 years, and it works well for him. He suffered a terrible stroke while he was a grad student at MIT back in the late 1980's. Then, he spent 5+ years regaining all of his abilities (walking, talking, etc). Typing is still difficult for him due to limited sensation in his hands, so he cooked up his Dragon/Emacs system. Now, he's a CS PhD student once again. Quite a story!
Evanescence is a real word that means "To dissipate or disappear like vapor." Still, whenever I hear that band's name, I think of Maria Schneider's first album.

I'm a jazz sax player, and have been a big fan of Maria Schneider for several years. She has been creating some of the most sophisticated and musically interesting big band music around since her first album in 1995 (Evanescence, which was also nominated for two Grammys). She has 3 or 4 other albums, and most have received Grammy nominations. She has been regularly winning Down Beat reader & critics polls since 1994.
Schneider is the heir apparent to her mentor, the late Gil Evans, who's music includes the famous Miles Davis collaborations Birth of the Cool, Porgy & Bess and Sketches of Spain. Her music is very accessible, though she's explores complex meters, harmonies, textures, and timbres. Her pieces tell a story, and often make reference to visual images.
I bought her latest album over the web a few months ago. It was something like $9.99 for 128kbps, $14.99 for 320kbps. It's an excellent album, but I still think that Evanesence is her best effort so far. By all means check out her band live if you ever have the opportunity. She always has some of the best jazz musicians in NYC in her group.

For a thought-provoking science fiction story set at the Large Hadron Collider, read Flashforward by Robert J. Sawyer.

Let us hope that Mr. Jackson has the wisdom to hire himself as the director!

I will definitely check this out. Many thanks!

Indeed! I'd say that Singularity is more of an action/mystery, whereas Brin's Earth is more speculative/philosophical SF.

Music CDs are typically $20-$30 in Japan, so I can see why iTunes would be popular there.

I guess we're the only two people on this board who care about this music. Well, hopefully the Grammy will bring her wider exposure.
