When I lived in Dallas a couple years ago, there was a restaurant that imported Dr. Pepper from Mexico because it is made with sugar instead of corn syrup. I was very surprised at the difference in taste. The sugar version is ten times better.
The cane sugar Dr Pepper is not imported from Mexico, it's made at the Dr Pepper plant in Dublin, Texas.
Interesting numbers. They're making, on average, $600 more per machine in '99 than they were in '89.
Unless the poster was being sloppy with his wording, you would do well to remember the difference between revenue and profit.
It is quite possible that with increased purchasing and maintenance costs, a $600 increase in per-machine revenue represents a reduction in per-machine profit.
Of course, one would have to see all the relevant numbers to determine what is actually happening.
The problem I see presented is: once you have your bot in place under twelve miles of ice, how do you get your signal back? Through a tether? Then how do you get the tether through all that ice without it freezing in place and jamming the probe during descent?
Put the tether spool on the (descending) bot. Then it wouldn't matter that the upper parts of the cable were frozen in place, because they don't need to move.
OK, maybe the number of deaths wasn't a record, but the Space Shuttle Challanger disaster should rank up there as a technological disaster (anyone remember Feynman's presentation about the O-rings?)
Damnit, read the intro.
In assembling this list of exemplary technological disasters,
weÕve omitted the most familiarÑthose whose names have entered into the language, like Bhopal, Chernobyl, Three Mile Island, Titanic and ChallengerÑin favor of some with fresher tales to tell and lessons to impart.
Actually I thought the domes didn't so much protect the antennas from the elements as hide which direction the antenna was pointed. With satellite photography what it is now, it becomes very easy to see things as big as antennas and see exactly where they are looking. The domes probably did a little bit of both.
The NWS puts protective domes around their NEXRAD dishes. Since they have no reason to hide the dishes from spying eyes, one can assume that its purpose is protecting the dish from inclement weather. Of course, they're not entirely successful.
Now, to have an air-surfboard, the stuff would have to be either pretty darn bouyant, or pretty big.
Actually, it's just going to have to be pretty big. I can't find the density of the human body at the moment, but it's reasonably close to that of water, so let's use that number, 1000 kg/m^3 (this also happens to be a nice round number, easy to work with). Air at sea level has a density of roughly 1.2 kg/m^3. In order to float, you need to get the average density of person+board down to that of air (actually you need to be below it, but neutral bouyancy is interesting enough).
So, assuming a 100kg person, for ease of math, and assuming a massless board with a density of zero, the board would have to have a volume of over 83 cubic meters. (assuming I did my math correctly) For the metric-declined, this works out to a cube about 14 feet on a side.
Human effects on bridges is hardly a surprise. Recall in 1981 when the Kansas City Hyatt's skywalk collapsed, killing 114, because the pedestrians were dancing (and the design was altered to ease construction). You'd think that would have been enough of a wake up call to the millenium designers to consider human motion.
The Hyatt's skywalk collapsed soley because of the change in design. The design change caused the walkway to fail to meet building code. Some civil engineers who studied the disaster were surprised it could support its own weight, much less the weight of the pedestrians.
The National Bureau of Standards concluded failure was just a matter of time. "The walkways," its probe found, "had only minimal capacity to resist their own weight."
The dancing people were by and large on the floor below the skywalk, participating in a dance contest.
The mistake that caused the Hyatt disaster was not one of failing to consider human motion in the design, but failing to consider the effects of seemingly minor changes in design.
As well as the distance from the equator, the fact that the earth is closer to the sun causes the seasons of various regions to be different.
Most of Europe, for example, although on the same latitude, has vastly different summers and winters than Toronto. Coastal variances also affect this, but a lot of it is because of the different distances from the sun.
No. The fact that Europe and Canada are at the same latitude means that they are the same distance from the sun (once you average out the rotation of the Earth).The difference in weather between the two locations is generally accepted to be due to the warming effect of the Gulf Stream.
I liked how the Chevy Nova wasn't selling in South America. Eventually they figured out what "No Va" means in Spanish.
This story is not true. "Nova" and "no va" are distinct in Spanish, and the Nova sold well in spanish-speaking countries. Please do not repeat this story as true again.
I know, I know, I shouldn't feed the trolls, but this irks me a lot. Do you have any concept of just how vast "outer space" is? We could go on using and destroying world after world for literally billions and billions and billions of years and we will NEVER RUN OUT. There are vastly more resources in space than there are here on earth. We *can't* abuse space, no matter how hard we try, becuase, for human purposes, there is a virtually limitless amount of energy (and thus matter) out there
Until we run into a vastly technologically inferior species who uses one of our own spacecraft, a laptop, and one nuke to destroy our mothership.
Interesting idea, but I believe it may be prevented by light having zero mass.
e=mc^2
Photons have a tiny mass due to their energy.
OTOH, black holes of significant size are supposed to be able to attract light with their gravitational pull.
This is not limited to black holes. During the 1919 solar eclipse, astronomers observed that the Sun's gravity was bending the light of distant stars, thus confirming general relativity.
With black holes, the gravity is so strong that a photon's path gets bent so much that it can never escape.
What about trapping light in gravitational orbit?
Is it possible? Can you calculate and model such a thing?
That's the definition of the event horizon of a black hole. Beyond the event horizon, gravity is weak enough that light can escape. Inside, light gets pulled to the singularity. But at the horizon, a photon can circle forever.
So while you could trap light using gravity, you're not getting it back.
Get yourself some random data (real random is of course somewhat hard to find! but the output from a crypto-strength RNG is OK) and zip it.
Now the output from deflate is NOT random
Note that I'm not saying you can compress ANY data, (I just said you can't compress compressed streams for instance!), but random data is not impossible to compress, just quite hard.
You don't seem to see the big flaw in your argument. What if your RNG output is a valid zip file? Or a JPEG, or some other already compressed format?
With a true random number generator, all sequences of bits of a given length are equally likely. Which means you can get valid compressed files out of it, or even all 1s for that matter.
Unless I'm mistaken... The darkside of the moon, is dark because it is always away from the SUN not the Earth. So it would only need to store the information until moon moved around, and the darkside pointed back to the earth
I'm going to contribute to the rampant correction of misconceptions here. (have to do my part)
THERE IS NO PERMANENT DARK SIDE OF THE MOON
There are permanent near and far sides to the moon, as viewed from Earth. The same side of the Moon is always pointed toward the Earth. The "dark" side of the Moon is whichever side of the Moon is pointed away from the Sun at the time.
The fact that the Moon does not rotate relative to the Earth is the whole point of putting a radio observatory on the far side of the Moon. Astronomers want the Moon between their radio telescopes and the radio noise of human civilization so they can observe in peace.
Other posters have explained how one could communicate with such a facility, given that it's on the far side of the Moon, so I'm not going to go into that.
A "new" moon occurs when the Moon is closer to the Sun than the Earth.
Your post needs a little clarifying, because this sentence is a bit ambiguous. A new moon occurs when the Moon is closer to the Sun than the Earth is to the Sun, that is, when the Moon is roughly between the Earth and the Sun.
New Moon Earth---Moon-------------Sun
Full Moon Moon---Earth--------------------Sun
Someone reading your post might get the impression that the Moon manages to move such that the distance from the Moon to the Sun is less than the distance from the Moon to the Earth, and there's already too many people who are confused about astronomy posting to this article.

It takes a decent amount of force to bend that reinforcing reinforcing bar.

No, really.

I tried making a mandelbrot set table once.
I gave up because it seemed like there was always an endless amount of detail work left to do.
Damnit, it's a HYPHEN !

That's "Klaatu barada nikto". It comes from the sci-fi classic, The Day the Earth Stood Still.
