hmm... is this 664, 665, or 666? There could have been some apocalypse-related joke if it was the latter. Nonetheless, this joke was pretty good, and it is surprising only one person has commented on the state of the antique furniture. BHG should focus on something larger, though, like his theft of a nuclear submarine.

Actually, Friday's ought to be the real 666. Randall started indexing from "1" for some reason...

this comic immediately reminded me of a calvin & hobbes strip. if you don't recall which one, then you don't deserve to know.

Just remember that something like this is always better than a supernatural explanation. Oakum's razor demands it.

LOL

That's probably been said over and over, but don't all, I mean ALL supernatural events become doubtful when high enough tech is involved? False memory implantation could make you believe in anything... hell, doesn't hypnosis already makes that possible?

And yet we relly in feelings... "I feel this means a superior force..." Hell, how can we still trust this kind of feeling? I feel love can bloom, and I hell KNOW it's a complete sham. For instance. Yet, we're programmed to feel it.

All I can say is I hope Joe Nickell makes an appearance in a future comic to give BHG his come-comeuppance.

I was expecting a 666 joke as well (followed by a real-life apocalypse triggered by the xkcd apocalypse) but this is way better. :D

To the people saying this is really #665: It's almost as if you didn't know about the super-secret hidden comic that makes up for #404. I don't even know where you got 664 from. (What does indexing from 1 have to do with it? That way #42 is indeed the 42nd comic.)

Yay! My first GOMH! moment!
A few days ago, I came home two and a half hours before I was supposed to. My dad failed to notice my arrival, even though I said hello. So I go to my room, change clothes, and begin to spy on my dad. He goes to the bathroom, comes out turning off the light, by the time he comes back to the kitchen I turn the light back on....


Truly evil. But pre-empted by the old black & white movie "Gaslight" which put this perversion into a lot of impressionable minds (like those of my folks. I'm sure of it).

Some years ago a friend of mine spoke of his neighbors who lived on a boat in San Pedro. "Psychologists - especially two of them - should never be allowed to have children" he said. He said his neighbors either turned a light on or turned one off every time their child sneezed, from the moment he came home from the hospital. A few years past that discussion a naptha tanker blew up rather dramatically near their dock. I've always wondered about that. Correlation isn't causation, but sometimes it can sure dilate the pupils.

It's pretty easy; I've done it many times. All you have to do is walk on the balls on your feet so your toes don't touch the floor. Then again, it only works with soft-soled tap shoes.

my plan involved active noise cancellation though, a good mike, speakers, and it plays back the sound of my footsteps offset by 1/2 periods.
i guess this would work for hammers too.
does anyone know how effective active noise cancellation is for sudden loud noises? my dad says they used it around all the heavy equipment at his job


To my knowledge it does not work well at all. The problem is that sound is being sent out in 3-D space and you can't cancel the waves in all the directions it is spreading easily. Much easier is stopping it as it attempts to enter the ears because the direction, volume, etc are all knowable at that one spot and thus much easier to match.


I think the real problem is how rapidly the wavelength gets short as the frequecy rises. As a rule of tumb, you have to start taking into account propagation effects if your device is more than about 1/10 of the wavelength. The (temperature dependent) speed of sound is about 300m/s. This means at 10 HZ (Wavelength 30m), your noise canceling device has to have dimensions of less than about 3m to allow you to ignore wave propagation (Which you have to do if you don't know where the receiver is). At the just-audible 30Hz freqency (L 10m), you are down to 1m. At 300Hz, the lowest frequency in the pass-band of telephones and low-end stereos (L 1m), you have only 10cm (about 4 inches) to work with. At the upper end of the telephone pass-band (3000Hz, L 10cm), you noise source and canceling apparatus have to be within about 1cm (about 25/64 of an inch).

It's not really possible.

Kids these days!

You don't need a mircocontroller. You can do it all (in real-time) in the analog domain with an OP-AMP (essentially an analog computer).

Faulty reasoning. mobilegamer999 clearly used the term "666'th" that I believe represents enumeration of physical objects. The 0'th comic represents a null comic.

It has been argued that since 404 is also a null comic, all subsequent comics are "off by one." However, you (serrath) seem to be arguing that neither comics '0' nor '404' should be considered 'null' comics. In effect, you are looking at the comic numbers as labels, rather than simple enumeration. You can find the actual labels Randal assigned here.

Edit: I suspect my reasoning is faulty here, but can't figure out exactly where I went wrong. (Maybe we should drop it)

Edit2: I think I figured it out: by ignoring the assigned numbers, serrath is doing enumeration as well. I neglected to explain why the counting of physical objects has to start a 1. The answer: '0' represents the absence of objects. This of course is convention established through history. The Romans did not even have a number representing the absence of objects. I'm sure yes can chose another number such as "-1" to represent the absence of objects, but there is little historical precedent.

I have an idea.
Have you seen commercials for the auto-hammer? (craftsman)
It basically vibrates nails into wood.

What if you jacked up the frequency of the vibration to above human hearing range?

Okay, not technically silent, or really feasible at all, but hey...

How about a combination of a suction cup and pnuematic press, though if it goes wrong a loud pop is likely to wake up the subject / victim.

Did anyone else notice that there is no such organization as the "American Skeptics Society?" It is simply known as the "Skeptics Society."

What makes this funny?

"American Skeptics Society" would be ASS. So, the chair of the ASS...
Funny...I wonder if it was intentional.
