That doesn’t explain it at all. It’s just where the phrase comes from.
In 1971, when I was 13, my cousin Janet, age 16, was killed. She lived in the Chicago area. She was missing for a few days and they found her body in the woods where she frequently took walks. Her body was hidden under a pile of leaves. She was shot in the chest. To this day,no one knows what happened.
It is a true unsolved mystery.
Hopefully this won’t remain unsolved forever, but it is bugging the heck out of me right now. A few weeks ago I took our camera along on a weekend trip. It was still in my purse the next day when I went to work, I know this because it was heavy and it irritated me that day - I thought to myself, remember to take the camera out when you get home. I didn’t, but the next morning as I was about to leave for work, I again noticed my purse was heavy, and then remembered to remove the camera, setting it on the counter by the door on my way out.
A few days later I wanted to take a picture and went to get the camera, and it was gone. Gone as in I looked all over the house, including in places it could never be, and on the off chance somehow the dog got ahold of it and hid it I looked outside and in every corner. It’s just gone.
Now we’re in the strange predicament of whether or not to buy a new camera or wait and see if this one turns up. I really don’t want to buy a new one - this was only about 2 years old and kind of expensive. I try not to think about it too much because it really frustrates me…where is it? What happened to it? I’m beginning to think someone might have stolen it, but I don’t know how that would have happened either.
Not a really good “life mystery” but it’s bugging me right now.
What happened to auntie em’s Missing Coworker???
I’d say by cropping the signal at the end. A rect function (finite) transforms to an Si-function (infinite), but since the amplitude of the Si-function is decreasing over time, you don’t really lose much, if you simply cut it off after a while.
Then again… You already knew that.

don’t you know that all human living quarters have little gremlins, that tend to move things around. That’s why a lot of us can’t seem to find something altough we know we left at a certain place.
look in your underware-drawer:D
or, if you saw the Sixth-Sense, you’d know it’s a friendly ghost that just picked it up, looked at, then placed it somewhere else, not out of meaness
I don’t think that’s it. If you cut it off in time, you create a sinc in frequency, not time. I think it’s just that the radio signal is not a finite bandwidth, just nearly so. It goes through a bandpass filter, but no bandpass filter is perfect. The higher and lower amplituse are attenuated so far as to be insignificant, but still non-zero.
When I was in grade school in the 1960s, there was an abandoned silo near my house. It was made of cast concrete, and the ladder up it was simply the 3/4 inch rebar in opening. The top maybe eight feet of the silo was a large water tank. You just reached the bottom of the water tank by climbing up the ladder. From a distance, you could see some sort of hatch on the roof that led into the tank, but there was no practical way to get up there since the ladder stopped at the bottom of the tank.
Being young and stupid, my best friend at the time and I used to climb up the ladder to scare ourselves with the height.
My friend’s older brother was in college at the time. His older brother was heavily into hard drugs, guns and motorcycles–really a bad news type of guy. So bad, in fact, that several years later he shot and killed their father.
Anyway, for some reason, the older brother took a hack saw and spent hours cutting through the top three rungs of the ladder. He claimed he done it because he had climbed up on the roof and put something in the water tank that he never wanted anyone to ever see.
I wonder to this day why he spent all that time cutting the rungs. Did he really get up on the roof (a near impossibility) and put something in the tank? If so what (or who) was it? I never really thought about it until he killed his father, and I realized he was capable of anything.
The silo was knocked down a few years ago to make way for houses. But anything could have been missed in all the rubble.
Francesca Thanks for the link - which adds the even deeper mystery of why someone would take the time to stop and photograph a sign like this… without going in to find out what the heck was going on.
Anyone know what state has a Hayward and a highway 880? I’m going to call the local library and find out what the heck this means. (“Stop casting” sounds like a process.)
Well, it looks like this thread may finally be going somewhere! Thanks for sharing everyone.
Sorry, clean shaven with a full head of hair here, but welcome to the slackers club, brother! 
Actually, I can’t really claim to be as I described anymore: from November to May I dated a hyper-ambitious girl, and thanks to her, while I still don’t exactly want to do anything with my life, I now feel horribly inadequate and know that I’d be miserable living the independently-wealthy-playboy lifestyle. Problem is, she didn’t pull me all the way over to the other side, so I’m torn, stuck halfway between ambition and lazyness! Actually, I guess that’s another real-life mystery: why do some people instinctively feel they have a “calling,” while others don’t?
When I was 10 or so, we had some relatives coming for Easter. I took a dozen plastic eggs, filled them with M&Ms and other candies, and hid them around the first floor.
Cut to the Great Easter Egg Hunt.
No eggs.
Anywhere.
It can’t have been the cats, because how could cats grasp plastic eggs with their little paws? And where would they have put them, anyway? And I knew where I’d put these things: under the couch, on the windowsill, and so on.
No eggs. Just two very disappointed cousins, and one very small Rilch.
Since the poster linked to a UC Berkeley site, I’ll assume we’re talking about Hayward, CA, 20 miles or so South of Berkeley on Highway 880.
My guess is that the place is a foundry, and it’s their motto, not to poorly cast and get porous results.
When I was little, I had a friend named Bettina. Her family moved away when we were eight, but she said they would move back in the seventh grade. Of course, she never returned. Her house hasn’t been sold - it just sits there, falling apart, with a no trespassing sign on it. Sort of spooky to think I used to play there.
I also lost a camera a few years ago, which bums me out. I was carrying it around at a friend’s Christmas party (her last before she died), and somehow it got set down and never picked back up. Man, I want those pictures.
What’s Clifford Algebra? Even the website of the International Clifford Algebra Society doesn’t give much of an explanation.
When I was an undergrad in college I got involved in an amicable discussion with a guy at the University of Helsinki regarding Marilyn Vos Savant’s article in which she claimed to disprove Andrew Wiles’ proof of Fermat’s Last Theorem. About a month later, the math department received a large envelope addressed to “Professor Sublight, Math/History Department”. It turned out that the guy was a professor, assumed I was too, and wanted to collaborate on a paper on math and society. Included with his letter were clippings of the articles he’d published, all of which were on the subject of “Clifford Algebra”. When I showed them to my math major roommate, his eyes went wide, he gave a choked little squawk, then ran off and hid in a corner. I sent an email to the prof thanking him and explaining that I was still working on my BA, but never heard from him again, so I never did find out what Clifford Algebra was used for.
I believe this site gives a fairly easy to understand, comprehensive introduction of Clifford Algebras for the layman.
I was going through my stuff one day and I found a poster with an extremely kitschy drawing of an angel and two children in an idyllic landscape. On the back were several quotes from the KJ Bible, along with texts about gardian angels and accepting Christ as your saviour and such.
I have no recollection of ever receiving such a thing, and owing to my geographical wherabouts, the odds of coming into contact with someone likely to hand me out such a poster were extremely low. Low enough that I would have remembered if someone did.
To this day, I don’t know where it came from.
I am aware of this, and I did look in my underwear drawer:( . I looked everywhere - even in places that made me say, ‘why am I looking here, there is no possible way it could have gotten here.’ It’s gone. I don’t know what could have happened, but the scenarios are getting stranger and stranger. Someone broke into the house and stole only that? Sleepwalking? The dog ate it? Some sort of vortex?
I’ve misplaced my good glasses. You know, the ones that don’t make me look TOO geekish…I remember falling asleep on the couch and my husband taking them off my face and putting them on the table by the couch…I’ve looked between the cushions, under the pillows, under the couch…
Ooo, maybe I can help. I recently lost my cell phone on the couch, and naturally, as brilliant as I am it only took me a day or so to think of calling the number and following the ring.
Turns out that it had slipped down between the cushions, down the armrest and was resting inside the liner on the bottom of the sofa. Once I found it there I was able to manouver it back up to the side of the armrest with one hand and reached down with the other hand and grabbed it. If that had not worked I was going to partially remove the liner.
To this day, I still have no idea what my mother did with all of my Transformers toys from when i was a kid (I’m 20 now, BTW.) She claimed she did not throw them out. They originally were always in my room until I was in seventh grade, just sitting in a large basket, then my room was re-done, new walls, new paintjob, etc…The toys were gone after that. I have looked numerous times in the attic, garage, and basement, but to no avail…
