1) To provide you with specific help, you need to supply more details
on the type of project you're contemplating.
2) To make quicksand, you need a bed of sand with some sort of conduit
running upwards towards the surface. Pump water thru this conduit at
a velocity just barely sufficient to dislodge the sand grains from
resting on one another - they're almost in suspension like a slurry.
At this flow rate, the downward forces (gravity) on the sand grains
are just balanced by the upwards flowing water, so there's nothing
holding the sand grains together.
(The above is an abbreviated version of the explanation my Groundwater
prof gave us this semester - blame me if it came out wrong, not him)
We took a field trip down the Dismal River in central Nebraska and
some of us took the opportunity to swim in the quicksand/boiling sand
springs along the river. It was pretty strange, because the density
is so high you can't sink in the stuff, plus you come out with pockets
(and everything else...) full of sand.

The small town of Cornville has several interesting springs very close
to the paved highway. The town is located about 1 1/2 hours North of
Phoenix. Take I-17 North to the Cottonwood/Jerome exit. Turn left onto
highway 260 until you reach Cottonwood. Turn right at the 3rd
stoplight. (next to Sizzler) This will put you on hwy 89A. Take the
Page Springs turnoff. As you near the creek there are areas to pull
off the road. You can see Bubbling springs, (look closely and you can
see the sand churning), Page springs, and several others. Hope you
find them, have fun.

Did you know that 100 years ago, science didn't know how to

to the moon, assemble a computer, forecast the weather, or
transmit TV pictures? The universe, right down to the tiniest

Maybe that description will indeed be God, but there's certainly
no evidence of that at this time. There IS evidence that there
are quite non-God-like forces doing this instead.

Hmmm. Really? The Hohmann transfer ellipse between Earth and Mars
has a one-way travel time of 259 days. It is my understanding that the
Hohmann transfer ellipse is the least-energy route of travel within a grav-
ity well. Also, all the trips to Mars that I can recall have taken at least
this long. I have often wondered whether we would subject astronauts to
over a year of weightlessness (a round trip would be one year, five months!).

I believe that the dinosour bones found in Australia were not from your
average 'great lizard'. I think I recall reading that these were
more like small chicken-like animals, unusually adapted for the cold of
Australia at the time. Indeed, they may have had to have been quite
different from the rest of the reptiles as (if I recall correctly again)
Australia was quite far south at the time, especially Dinosaur cove.
Don't take this as gospel. It's from memory, and that means its probably
wrong.

Mars 3 left earth 5/28/1971, arrived 12/2/1971

According to J. David Archibald's book Dinosaur Extinction and the End of
an Era (1996), it seems most likely that finding some dinosaur fossils in
younger strata could be a result of old sediments being reworked and
redeposited with the new, thus creating the illusion that of dinosaurs
existing beyond the K/T boundary. This is one of the four controversies
that he addresses in the second chapter of his book.

for one thing each person you add is going to be at least
another 100 pounds( more like 150 but that is a minimum).
then you have to provide space for the person to move around
in, which will end up making the craft a little bit heavier
as well. then the person is going to need food, air and a few
other things to stay alive. this will add even more weight.
you mentioned fuel, you do realize that none of the probes sent
to mars ever left the surface once they landed. so all the fuel
needed to come back would be extra weight from the begining.
the bigest things holding up a mars mission with people is
first, no wide spread support for it until recently
and second the much lager mass the object will have both to keep
the people alive and get them back realitively safely.
now if you are talking about just orbiting the planet then the
fuel increase( which i think would be the bigest part of the mass
of a craft that lands on mars can comes back) would not be that
much larger. but you do still have to keep the person alive for
at least 8 months, think about how much food you eat in 8 months:)
the temperature would not be a big problem, actually the moon can
get colder than mars. the astronauts would have to be inside the
craft or space the entire time anyway so they wont really feel how
hot or cold the planet is.
i dont know how exactly gravity relates to escape velocity, but i
do remember that doubling gravity will more than double escape
velocity. i want to say that you square the increase in gravity to
get the increase in escape velocity but that dont sound right.
the wind/sand storms would be new type of consideration, but if
the astronanauts are inside the craft during them and no serious
equipment is on the outside of the craft and unprotected i dont
think it would be a problem unless the winds are capable of blowing
over the craft.
as for it being international, that is one of the other reason
holding up some of the plans for a mars mission. the prefered
location to lauch and retreve such a mission is from a space station.
this way you remove a couple of days off the time and remove having
to include the mass of the fuel needed to get off earth and land
back on earth from the craft. the moon would work using the same
logic, it just would still require the fuel to get off the moon
as part of the craft weight. i personal hope that any kind of
manned mission is sent to mars it is at least on paper an international
thing if not in reality.

Just because the internet is the sum of millions of minds doesn't mean

of netizens were points of light, a single lit candle would blind us
with its actinic glare.
You see, a friend who knows someone high up in the government told me
what's really happening is that the Forces of Evil are softening us up.
After a few good scares (like Good Times and PKZIP300) that turn out to
be utter lies, you'll have your gaurd down when the real virus of the
apocalypse strikes...
Now if there really was a net terrorist underground (and everyone knows
there isn't; even the CIA freely admits there is no such thing) wouldn't
a long range plan like this be an excellent way to bring utter chaos
into our lives one day? Talk about your ultimate Trojan Horse! No one
would expect it, and it would probably appear in the world as a new
"super virus shield" given away for free by this supposedly
altruistically minded organization. What an excellent front! We'd be
suckered in one and all.
Remember that Twilight zone episode about the aliens who came to earth
and fixed up so many things for us humans, leaving behind their book,
"How to Serve Man"? Remember the last scene as the hero is about to get
on the space ship for a trip to the alien's planet, and his colleague
rushes out of the crowd and screams at him, "'How To Serve Man' -- It's
a COOKBOOK!" Food for thought, ...so to speak.
Think about this, conspiracy fans: if some para-military group wanted
to take out the electronic world in one stroke, wouldn't it be funny if
they started years ahead by building and distributing real anti-virus
software, but then at some time determined by their anti-christ leader,
after gaining the world's trust and getting their stuff installed on all
machines connected to the net, the final anti-virus release was in fact
the actual virus itself! And who's research lab would be the most
capable of building a totally undetectable killer virus, eh? Do you
think no one else has thought of this? haha. (or muhaha, as the case may
be).

during my undergraduate studies, our soil mechanics lab was equipped
with a large plexiglass tank that possessed water influent ports from top
to bottom. The tank could be filled with various sediments/materials, a
load was added to the sediment surface at the top of the tank, and
water was then added from an combination of port (a wetting front could
be simulated from the bottom or top). Thumping the tank or adding
vibration resulted in liquefaction and load settling.

Actually, as far as it can be said that science does explain things... it
does do a pretty good job now at explaining what holds atoms together.
The proof? We can explain it well enough to predict things like the
lifetimes of proposed radio-isotopes. Nuclear medicine, nuclear
warheads, nuclear power plants, are all evidence of how far we've come in
understanding nuclear forces. The fact that research attention now
focusses on particles much smaller than atoms is further evidence.
This particular argument is a subset of the "God of the Gaps" fallacy,
and one that you've just reminded me I really should tackle in my pages
on religious pseudo-science (since it is fairly commonly cited). You can
check out my page at http://www.freenet.mb.ca/iphome/a/accc/godofgap.html

Subject: A one-week tour of Utah geology
From: Kevin Whilden
Date: 22 Oct 1996 17:29:54 GMT
Hola,
My name's not actually Kevin Whilden, but Aaron Fox. I'm an
undergrad at the University of Washington and I'm helping plan
out the route and sights to be seen on our annual spring break
trip.
We're entering Utah from the south, headed up from Monument
Valley to Moab and then back through Nevada a week later.
I was wondering if anyone who has experience in Utah field
geology could suggest some interesting field trip stops, or
even better, a guidebook (GSA tourbook?)
We've already got Canyonlands and Dinosaur National Monument
on the list.
We've got the Roadside Geology book, as well as a Geologic
History of Utah by a BYU professor (Heintze? sp?).
The crew is a mix of undergraduate students with no particular
specialties (a few petrology nuts like myself, couple
geomorphologists, ect ect).
Any comments, suggestions, resources or tips would be
gratefully accepted. I lurk the group about 3-4 times a week,
or you can reach me by email at :
afox@u.washington.edu
Many thanks,
d.

the trip would not have to be under weightless conditions. you could
spin the ship with little trouble and create the effect of a small
gravity inside the ship.
and astronauts have been in space for over a year before. one of the
russians i am fairly certain was in space for close to 18 months once.
and besides mars has gravity so at worst they would be weightless for
the time it takes to get there.

the time it takes to get to mars depends on how close the planets are
to each others orbits and at what point they are on their orbits. the
number he gave sounds to me like the maximum number for it from what
i remember. but clearly the time varies in relation to the locations.
