Long Light

[[A man in a car, sitting at a red light.]]
Man: This light always takes forever. I'd like to smack the idiot who designed this intersection.
[[An engineer steps up onto the hood of the man's car.]]
Engineer: Hi.
Man: Who the hell are you?
Engineer: I designed this intersection.
Engineer [[arms spread outward]] : You're right - I should have just made the light shorter! Never mind the hours of simulation and testing I did. Never mind that this intersection interacts with it's neighbors in a complicated way and it took me a week to work out timing sequences that avoided total jams.
Engineer: Clearly, I'm a crappy engineer and you have a better solution. Go on, show me your proposed timings.
Man: Get the hell off my hood before I start driving and fling you into traffic.
Engineer: You can't. Light's red.
Man: Well, when will it change?
Engineer: Tuesday.

Electromagnetic Spectrum

((Everything is one big panel.))
The Electromagnetic Spectrum
These waves travel through the electromagnetic field. They were formerly carried by the aether, which was decommissioned in 1897 due to budget cuts.
Other waves:
- Slinky waves [[Two people hold the ends of a tangled slinky.]]
- Sound waves [[There is a snippet of a frequency band. Between 20 Hz and 20 KHz is labeled "Audible Sound." Towards the top is a line labeled "That high-pitched noise in empty rooms."]]
- The wave [[A row of people does a wave.]]
[[Three parallel scales are across the bottom. The first is lambda (m), ranging from 100Mm to 100fm; second is f (Hz), which starts at 1 Hz and reaches 100 THz about 2
3 of the way along, after which the labels read "other entertaining greek prefixes like peta- exa- and zappa-"; last is Q (Gal^2
Coloumb), whose labels are 17, 117, pi, 17, 42, theta, e^pi-pi, -2, 540^50, and 11^2. Above the scales and lined up accurately with the first two are the following:]]
- Power & Telephone (100Mm to 1km)
- Radio & TV (1km to somewhere between 1m and 10cm); above that are many boxes showing subranges (AM, VHF, UHF, 14
7 NPR pledge drives, a very thin band for the space rays controlling Steve Ballmer, 99.3 "The Fox," 101.5 "The Badger," 106.3 "The Frightened Squirrel," cell phone cancer rays, CIA, ham radio, kosher radio, shouting car dealership commercials)
- Microwaves (a bit more than 10cm to a bit more than 1mm); it also has subranges (aliens, just below SETI, wifi, FHF, brain waves, sulawesi, gravity)
- Toasters (about 1mm to about 100 micrometers)
- IR (about 100 micrometers to somewhere between 1 micrometer and 1 nm); above that is a bell graph labeled "Superman's heat vision," with a motorcycle driving up the left side labeled "Jack Black's Heat Vision."
- Visible light (and, under it, visible dark); above that is a bell graph labeled "sunlight." There's a breakout chart above it showing the visible spectrum from 700nm (red) to 450nm (violet). There's an arrow pointing to where octarine would be, somewhere off to the side. Above that are bars showing the absorption spectra for hyrogen, helium, Depends(R) (yellow only) and Tampax(R) (red only).
- UV (about 100nm to about 10nm)
- Miller Light (a thin bar around 10nm)
- An unlabeled section with a thin line above it showing the frequency of the main death star laser
- A blocked-off portion labeled "Censored Under Patriot Act."
- X-rays (from about 1nm to about 10pm); a line above shows the frequency of mail-order x-ray glasses. Somewhere vaguely above the 10pm mark is a potato.
- Gamma
cosmic rays (10pm and smaller); above that is a bar marked Sinister Google Projects which also trails off into higher frequencies, and blogorays, which are slightly lower.

[[Man and woman standing by a train]]
Woman: I'm bad at goodbyes. At some level I never think they're for real.
Man: They make me think of T. H. White's Merlin.
Woman: Oh?
Man: He lived backwards, remembering the future and not the past. To him, final goodbyes meant nothing, while first hellos were tearful and bittersweet.
Woman: Huh - so over the years he'd forget all his friends.
Must've been lonely.
Man: Yeah. He ended up just sitting around at home watching DVDs all day. The best was the time he rented 'Memento'...

Girl: Why tell me this?
Clone: You're curious and smart and bored, and all you see is the choice between working hard and slacking off. There are so many adventures that you miss because you're waiting to think of a plan. To find them, look for tiny interesting choices. And remember that you are always making up the future as you go.
Girl: So, wait, what *is* this place? Am I going to wake up thinking this was a dream?
Clone: This is... think of this as after the game, outside the theatre. To go in, I had to suspend disbelief, forget the outside.
Girl: So you... Huh. Why give me hints I'm going to forget?
Clone: You'll forget this trip but I think the hints should stay with you.

Conspiracy theories represent a known glitch in human reasoning. The theories are of course occasionally true, but their truth is completely uncorrelated with the believer's certainty. For some reason, sometimes when people think they've uncovered a lie, they raise confirmation bias to an art form. They cut context away from facts and arguments and assemble them into reassuring litanies. And over and over I've argued helplessly with smart people consumed by theories they were sure were irrefutable, theories that in the end proved complete fictions.

Comic Fragment

Editor's Note: Mr. Monroe has been missing for several days. We have received no submissions from him for some time, but we found this single panel on his desk in a folder labeled 'MY BEST IDEA EVER' . It is clearly part of a work in progress, but we have decided to post it in lieu of a complete comic.
[[Single panel illustration in color with one small panel embedded within, showing a zoomed-in version of Janeane Garafolo on a motorcycle. The background is a gray landscape beneath a falling space station, a large volcano with smoke rising the only discernible feature of the landscape below.]]

The volcano was looming ahead, and her tranquilizer pistol only had six darts left - barely enough to bring down even ONE tyrannosaur.

Dream Girl

Man 1: I had a dream that I met a girl in a dying world.
It was all coming apart. Hairline cracks in reality widened to yawning chasms. Everything was going dark and light all at once, and there was a sound like breaking waves rising into a piercing scream at the edge of hearing. I knew we didn't have long together.
She grabbed me and spoke a stream of numbers into my ear. Then it all went away.
[[A girl grabs him as the edges of the panel crack and tear]]
I woke up. The memory of the apocalypse faded to mere fancy, but the numbers burned bright in my mind. I wrote them down right away.
[[A note reads: 42.39561 -71.13051 2007 09 23 14 38 00]]
They were coordinates. A place and a time, neither one too far away.
Man 1: What else could I do? When the day came, I went to the spot and waited.
Man 2: ...and?
Man 1: It turns out wanting something doesn't make it real.

x: Number of male (or female) cast members.
n: total number of cast members.
[[A graph plots pairings (for large casts) against cast makeup. Each of the above equations forms a curve.
"Gay cast" starts high for an all male cast, dips down at 50
50 cast makeup, and then rises again for all female.
"Straight cast" starts at zero for an all male cast, peaks at 50
50 cast makeup, and then drops to zero again for an all female cast.

Perspective

Narrator: Sometimes, when I first wake up, I am caught in the horrible grip of perspective.
[[A person sitting up in bed]]
Person: It may be a jewel of open source, but Firefox is JUST A BROWSER. It shows WEBPAGES. What the hell is WRONG with us?
Narrator: Fortunately, this subsides quickly.

Command Line Fu

[[Two men talking]]
Man 2: Last night I was watching videos with this girl and my monitors kept turning off - even though I had disabled power save.
Man 1: Odd.
Man 2: However! I wrote a command to jiggle the mouse pointer every couple minutes to keep it from going idle.
Man 1: Not the first hack I'd try, but see? Linux has problems, but it gives you the tools to deal with them - and save your date!
Man 2: Actually, I was half an hour into the pointer scripting documentation when she got dressed and left.

Map of the Internet

Map of the Internet
The IPv4 Space, 2006
This chart shows the IP address space on a plane using a fractal mapping which preserves grouping--any consecutive string of IPs will translate to a single, compact, contiguous region on the map. Each of the 256 numbered blocks represents one
8 subnet (containing all IPs that start with that number). The upper left section shows the blocks sold directly to corporations and coverments in the 1990's before the RIRs took over allocation.

Person 1: I'm telling you, listen right here to the sets of rising notes following the opening section.
Person 2: Uh huh.
[[Person 1 indicates stereo]]
Person 1: And then right here, the transition into the chorus. _This_ is music. This is _art_!

Working for Google

Have you read about Google HQ? It sounds like an incredible place to work.
Man, I ain't going to be chained down in no corporate idea factory! They think just 'cause they've got a nice building and laid back culture, I'm gonna want to come in all day long and work on fascinating problems with the smartest people in the world.
[[One stick figure stares at the other]]
So, what, they turned you down?
I don't understand it! I even baked them a cake shaped like the internet!

IPoD

[[Character 1 - wearing a black hat - sits at a computer. Character 2 stands behind Character 1]]
Character 1: You see, statisticians communicate using IPoD -- IP over Demographics. For example, the header of the next packet I send will be encoded into the New Jersey death rate.
Character 2: So you're going to hack the census bureau and change the number of reported deaths?
Character 1: Guess again.
Character 1: Hey, have you seen my crossbow?

My dad was always the one who taught me about science, but looking back, I'm starting to realize how much my nerdiness was influenced by my mom.

Mom: No, Dear. You know you only get that privilege when your age is one less than a multiple of three.

Nash

[[Two men stand talking two each other. The first man is pointing off the panel]]
First Man: Hey, Dr. Nash, I think those gals over there are eyeing us. This is like your Nash Equilibrium, right? One of them is hot, but we should each flirt with one of her less-desirable friends. Otherwise we risk coming on too strong to the hot one and just driving the group off.
Second Man (Dr. Nash): Well, that's not really the sort of situation I wrote about. Once we're with the ugly ones, there's no incentive for one of us not to try to switch to the hot one. It's not a stable equilibrium.
First Man: Crap, forget it. Looks like all three are leaving with one guy.
[[Second Man shakes his fist]]
Second Man (Dr. Nash): Dammit, Feynman!

First Man: I mean it this time.
Second Man: Well, becoming a citizen takes work. Meanwhile, you have no money, half an art degree, and it's the start of winter. You'll freeze to death in the streets.
