A lot of taxonomic names end up being Shout Outs to things. Often it's to the scientist who discovered it or to the location it was discovered, but there are some more unusual ones:
A spongelike fungus is named spongiforma squarepantsii.
Interesting story behind Utahraptor spielbergi — scientists felt the raptors in Jurassic Park were too big, so when they did find ones at that size they named the species after the movie director. Velociraptors were about four feet tall. The filmmakers didn't think that would be scary enough and beefed 'em up. Sadly, though, Spielberg's lawyers rejected, so it was renamed Utahraptor ostrommaysorum, after John Ostrom, who discovered Deinonychus and established the dromaeosaurs as a family in the progress, and Chris Mays of Dinamation, which funded the expedition that discovered Utahraptor.
There are several flower varieties called Sailor Moon. Surprisingly, Naoko Takeuchi makes one of them as part of an artbook drawing, since she loves when fans homage her works, and compliments it back as she can.
Strigiphilus garylarsoni, a kind of chewing louse, after the creator of The Far Side and his frequently insect-related humour. And the Thagomizer!
Psephophorus terrypratchetti, a prehistoric turtle which is notlarge enough to appear on the Hertzsprung-Russell Diagram. Terry keeps a fossil of it on his desk. And Gingoites nannyoggiae, a Mesezoic plant. The "Ogg" multimedia format is not a reference to Nanny Ogg; however once the coincidence was pointed out, the makers named their audio format after Vorbis from Small Gods.
The trapdoor spider Myrmekiaphila neilyoungi, and inevitably, Aptostichus stephencolberti.
Heteropoda davidbowie, another spider species. Note that one of David Bowie's most famous early albums was The Rise and Fall of Ziggy Stardust and the Spiders from Mars.
Han solo — it's a trilobite. It has a double meaning, actually, as Han refers to the Han People of China, and solo is a reference to this being the sole species of the Han genus, but the author who named it also wanted to make a Star Wars shout-out.
The scientific name for the dinosaur Masiakasaurus is Masiakasaurus knopfleri — the expedition crews were said to be listening to a lot of Dire Straits at the time. Mark Knopfler himself once made an amusing self-effacing comment about how appropriate it was to have a dinosaur named after him.
In addition, one of the macrocycle inhibitors of the gene sonic hedgehog continues the reference. It is named Robotnikin.
Likewise, a retinal protein was named Pikachurin, due to its relation with electrical signals.
The POK erythroid myeloid ontogenic factor was originally named Pokémon, until Nintendo threatened legal action. Why? It's a master switch for cancer. It's given a generic name of Zbtb7
Celestial bodies are also often named for real or fictitious people, in a tradition dating back to antiquity when planets and constellations were named for the gods.
A scientist named a rock in the Main Asteroid Belt 18610 Arthurdent". Later, another asteroid was dedicated to the author: 25924 Douglasadams The naming of 25924 Douglasadams is itself a heartwarmer. The provisional name for it was 2001DA42. [2] The only comments that could be given were along the lines of "it was sort of made for him, wasn't it?"
The asteroids 12796 Kamenrider and 12408 Fujioka, named for the Kamen Rider franchise and its original star, Hiroshi Fujioka.
Asteroid 99942 Apophis. Even funnier, there is a small chance that the asteroid may hit Earth in 2036, so Apophis is our real-life enemy. (The name Apophis comes from Egyptian Mythology, but the asteroid's discoverers are said to be fans of Stargate SG-1.)
There's even one named after the fictitious Czech genius Jára Cimrman. Let's just say that the name of every other asteroid is a reference to something-or-other (since it's the discoverer who proposes the name, and there are few restrictions on the name choice.)
White dwarf BPM 37093 in the sky with a crystallized carbon core (read: diamond). Informally named: Lucy.
The dwarf planet now known as "Eris" was nicknamed "Xena" for 2 years while a final name and designation were decided. Its moon was officially named "Dysnomia" (Lawlessness) as a shoutout to actress Lucy Lawless.
Tanz Metal band Rammstein had a minor planet named after them.
All of the elements after plutonium, once they are actually synthesized, are named either for a famous scientist (einsteinium, bohrium, mendelevium, nobelium, rutherfordium) or an important location, usually the element's "place of birth" (berkelium, californium, americium, darmstadtium). An abandoned mine at Ytterby, in the Stockholm archipelago, has four elements named for it: erbium, terbium, ytterbium and yttrium.
Google's Wave service was named such because that's what communications were called in Firefly. The crash message is even Wash's infamous line "Curse your sudden but inevitable betrayal!"
Programmers love to do this. Examples include:
Soylent, a project to merge all contact info (e-mail addresses, IM screennames, etc.) for a person into a single account in GNOME (Linux-and-its-ilk desktop).
Plan 9 From Bell Labs, the successor to UNIX as Bell Labs' main research OS. Along with Plan 9 From User Space, a port of the main Plan 9 programs to UNIX-like systems. (and yes, userspace actually means something in context)
The TIFF standard specifies "An arbitrary but carefully chosen number (42)."
The ADA programming language, named after Ada Lovelace, who's often credited to be the world's first programmer. ADA was created under contract from the United States Department of Defense, which gave the ADA reference manual the number MIL-STD-1815. 1815 was Ada Lovelace's year of birth.
The Python programming language was named after Monty Python.
The term "Spam" for junk e-mail was named after the Monty Python sketch of the same name. Other people backronymed it to Stupid Pointless and Annoying Message.
While not a shout out to pop culture most of the time the codenames for AMD, Intel, and Microsoft products tend to be named after places they either do development in, take vacations to, or just because.
AMD's first in-house designed x86 compatible processor was called K5. Their next generation, K6, was when they said the K meant Kryptonite.
Upcoming iterations of Nvidia's Tegra system-on-a-chip series are codenamed Kal-El, Wayne, Logan, and Stark.
The Raspberry Pi (an educational- / hobbyist-market computing device with an ARM CPU, capable of running Acorn RISC OS) is available in "Model A" and "Model B" versions; this will sound familiar to anyone who remembers the BBC Micro. (It's no coincidence that this device was co-developed by David Braben, of Elite fame.)
Originally Colbert was competing for the naming of a space capsule, the name in second place was Serenity.
We swear someone shouted out "I see you,Russia!" before that pair's free skate...
Or it could more likely be a reference to the statement by Sarah PalinTina Fey that you could see Russia from Alaska, and that in itself gave her international relation experience.
Iron Maiden's drummer Nicko McBrain owns a restaurant, Rock N' Roll Ribs. The menu is filled with references to his band (such as "Appetite of THE BEAST", and the temperatures of sauce: Mild, Medium, Hot, Die with your Boots On, or Heaven Can't Wait).
Lucy, the fossilized Australopithecus named after the Beatles song "Lucy in the Sky with Diamonds".
Disneyland is full of these to former attractions. To whit:
In The Many Adventures of Winnie the Pooh, just as you leave the Heffalumps and Woozles part, if you look behind you, you can see three trophy heads - Max, Buff, and Melvin, from the attraction that once occupied that spot: Country Bear Jamboree.
Somewhere in the projector room in the queue for Indiana Jones Adventure, there is an Eeyore sign - that spot used to be the Eeyore section of the old parking lot.
In Autopia, there's a bronzed Midget Autopia car, referencing the long-gone attraction.
Swiss Family Treehouse, based off of the movie Swiss Family Robinson, once occupied the spot where Tarzan's Treehouse is now. A gramophone in Tarzan's Treehouse still plays the Swisskapolka
The Mighty Microscope from Adventures Thru Inner Space is still there - you can see it across from a mechanical arm that almost hits the Starspeeder 3000 in Star Tours.
An actual engine from the Mine Train thru Nature's Wonderland sits at the edge of the Rivers of America
Mike Fink Keel Boats transported guests along the Rivers of America until 1997. One boat, the Gullywhumper, is moored as a prop along the rivers.
There are four shout-outs to the House of the Future in Innoventions alone.
