I think they probably changed the name of the city again (probably several times). In the main thay seem to take delight in changing the name of the place every thirty years or so, thus it went from StPetersberg to Stalingrad to Leningrad and back again (They have a committee who's task it is to change names). Must be murder for the post office. I am also told, by my Georgian aunt, that there is another Leningrad out in Siberia.Originally posted by Dave
As the probe wreaks havoc on Earth, a Starfleet communications officer gives a readout on various cities around the world. One that he mentions is Leningrad.
Is this a new city built in the 23rd Century and named after that great Russian leader who is currently out of favour?
Or is it the city that used to be known as Leningrad, until it reverted to it's former name of St. Petersberg, shortly after this film was made, but reverts back again sometime before the 23rd Century?
It must be a challenge to write science fiction that stands the test of time.
I hadn't thought of that but it makes perfect sense.Originally posted by ray gower
My thought for tonight is. The race that sent the probe, could they have been the Aquatic Xindi?

Scientists in the US have developed a novel technique to make bulk quantities of glass from alumina for the first time. Anatoly Rosenflanz and colleagues at 3M in Minnesota used a "flame-spray" technique to alloy alumina (aluminium oxide) with rare-earth metal oxides to produce strong glass with good optical properties. The method avoids many of the problems encountered in conventional glass forming and could, say the team, be extended to other oxides (A Rosenflanz et al. 2004 Nature 430 761).
Glass is formed when a molten material is cooled so quickly that its constituent atoms do not have time to align themselves into an ordered lattice. However, it is difficult to make glasses from most materials because they need to be cooled -- or quenched -- at rates of up to 10 million degrees per second.
Silica is widely used in glass-making because the quenching rates are much lower, but researchers would like to make glass from alumina as well because of its superior mechanical and optical properties. Alumina can form glass if it is alloyed with calcium or rare-earth oxides, but the required quenching rate can be as high as 1000 degrees per second, which makes it difficult to produce bulk quantities.
Rosenflanz and colleagues started by mixing around 80 mole % of powdered alumina with various rare-earth oxide powders -- including lanthanum, gadolinium and yttrium oxides. Next, they fed the powders into a high-temperature hydrogen-oxygen flame to produce molten particles that were then quenched in water. The resulting glass beads, which were less than 140 microns across, were then heat-treated -- or sintered -- at around 1000Â°C. This produced bulk glass samples in which nanocrystalline alumina-rich phases were dispersed throughout a glassy matrix. The new method avoids the need to apply pressures of 1 gigapascal or more, as is required in existing techniques.
The 3M scientists characterised the glasses using optical microscopy, scanning electron microscopy, X-ray diffraction and thermal analysis, and tested the strength of the materials with hardness and fracture toughness tests. They found that their samples were much harder than conventional silica-based glasses and were almost as hard as pure polycrystalline alumina.
Moreover, over 95% of the glasses were transparent (see figure) and had attractive optical properties. For example, fully crystallized alumina-rare earth oxide ceramics showed high refractive indices if the grains were kept below a certain size.

I just wish to add that the Probe had no intentions of destroying Earth, it was boosting its signal because it wasn't able to hear the whales' response, which inadvertantly caused major destruction on Earth.Highlander II said:Just watched this one too - (skipping work is fun - i may have to do it more often!)
This is my personal fave, has been since i saw it in the theatre when it was released (my dad had this thing about the ST films - we had to go) anyway -- i like the time travel thing -- (anyone know if you could really do it that way?? )
Time travel - hey, don't ask me, physics was NOT my strong subject -- but i think the idea is really cool
the Whales -- nice idea that they showed what could happen to the planet if some things aren't corrected (lots of movies did this) - humans killed all the whales, and now this probe has come and may destroy the planet b/c it lost contact w/ it's 'missionaries' or 'officers' -- depending on how the structure of 'their world' was set up --- and Kirk and co have to fix the problem by taking their Klingon bucket back in time to find some whales --
then the whole scene in 1984 - the 'colorful metaphors' that Spock doesn't understand, and the 'nuclear wessels' and such -
i'm sure there are continuity errors in this one too - but i didn't catch them, or if i did, i don't recall them at the moment --
might i just say that, at least in this movie, DeForest Kelley is about the skinniest person i've ever seen? very weird ---
