I've seen something like that on History Channel, where if hot water or something is applied the metal remembers its orginal shape, and returns to it.

Example, get in a car wreck, apply hot water, body of the car is no longer damaged.

But, with the recent advances in Spider Silk Tech. this form-remembering metal will not be as powerful as thought.

Spider silk is known to be stronger then most, if not all, composite materials. I heard them speaking about making regular silk shirts that are actually bulletproof. This can also be applied to cars, trains, planes, boats, clothing, etc. While form-remembering metal may be powerful, but i think when Artificial Spider Silk comes around, that will be more powerful...

Or at least i think so...

I just saw this thread about this topic and followed the link to CNN...
Do you think the parents really cared, even if they have "Bad" backgrounds of their own with the police and courts?

It might be thougher than elastic metal, but can the shape of the Spider Silk change, as the elastic metal?

Tropical Storms

Unread postby Shan Ping » Tue Sep 14, 2004 6:20 pm

Seems like the hurricane season really took off this year. Folks in Florida have been hit by two major hurricanes already and in most parts still don't have power. The economy might be hurt from a whole state being put out of commision for that long.

Now there's another one... Ivan! The thing already ruined many peoples lives in Grenada and Jamaica. By the time someone reads this it would have probably made landfall in the U.S. It looks like it will hit the region between the Florida pan handle and new orleans... me... I'm between Biloxi and Mobile... :(

There is also another tropical storm on near the carribean islands... people in Southern U.S. and the carribean seem to be taking a beating this year... :(
I assure you I will not post much because I don't think there is a point to it!

How many people felt the recent earthquakes in California? I mean, they were pretty small (6.0 at Parkfield, pop. 37), but supposedly they were felt from LA to Sacramento. I only felt the one on Tuesday... the house was shaking, but I was in bed and too lazy to get out :oop:. I was thinking, "it's probably just people jumping around upstairs--I'll get out of bed when I hear stuff falling off the shelves and I know it's a real earthquake!" Not the best earthquake-surviving strategy, but fortunately it wasn't too bad!

Some people are saying that it was just a prelude to more seismic activity, and there's a 8.0 coming up :?:

If I recall the last great eruption from this volcano was 18 years.



Mount St. Helens a Volcanic 'Ring of Fire'

52 minutes ago Science - AP


By WILLIAM McCALL, Associated Press Writer

PORTLAND, Ore. - Three or four times every minute, Mount St. Helens shivered. Sometimes the majestic peak even shuddered, the trembling beneath reaching a crescendo, a magnitude of 3.3.

Slideshow: Mount St. Helens Erupts

The earthquakes that started a week ago — precursors to Friday's eruption — are a reminder that the 8,364-foot sleeping giant is but a part of a volcanic "ring of fire" so vast that it encircles the Pacific Ocean.


Indeed, the other 12 major volcanoes in the Cascade Range of northern California, Oregon and Washington state lie within this geological phenomenon as well.


The entire ring — from the tip of South America up through Alaska, Japan and the Kamchatka Peninsula of Russia, down through the Philippines and Indonesia into New Zealand — includes about three-fourths of the world's active and dormant volcanoes, scientists say.


Another one in the ring, a 12,533-foot volcano on Mexico's west coast, belched plumes of smoke and fired hot rocks down its slopes this week. The explosions were provoked by the collapse of a dome that had formed recently in the crater of the volcano, located in the Pacific coast state of Colima.


Most of the Mount St. Helens activity is related to shifting in the vast sections of the Earth's surface known as tectonic plates, continent-size chunks of crust and a lower layer called the mantle that move with molten layers below them.


Mount St. Helens and the Cascades lie near the edge of the Juan de Fuca plate, which is diving under the North American plate to create a 700-mile long "subduction zone" along the ocean floor that triggers earthquakes and pushes molten rock upwards.


Called magma underground and lava when it surfaces, the molten rock is forced up through fissures and weak spots in the crust.


Mount St. Helens lies along a particularly weak area of the crust, causing it to be the most active volcano in the Northwest over the centuries, said Jon Major, a U.S. Geological Survey (news - web sites) researcher in Vancouver, Wash. Its most spectacular showing was in May 1980, with an eruption that blew the top 1,400 feet off the mountain.


"It sits near the St. Helens seismic zone, an area where the crust is pulled apart a little bit," Major said. "That lets magma push up and explains why it's so active and others are not so active."


For example, Mount Adams lies only about 50 miles east of Mount St. Helens but has not erupted in thousands of years, Major said.


Mount Jefferson, which lies between Mount Hood and the Three Sisters in the Oregon stretch of the Cascades, appears to have been dormant since the last Ice Age despite relatively recent eruptions on neighboring peaks, he said.


In the rest of the Cascade Range, which stretches from Canada to Northern California, two of the tallest peaks — Mount Rainier in Washington state and Mount Shasta in California — both have erupted at least once in the past 200 years and have had several more eruptions over the last 2,000 years. Most were considered minor, according to USGS (news - web sites) figures.


Friday's eruption was nowhere near what happened 24 years ago, when 57 people were killed and towns up to 250 miles away were showered with rock and ash. About 20 minutes after Froday's eruption began, the mountain calmed and the plume began to dissipate, although small earthquakes resumed a few hours later.


The Northwest, in turn, has been relatively quiet compared to other areas of the ring, according to Jim Luhr, director of the global volcanism program at the Smithsonian Institution (news - web sites) in Washington, D.C.


The Aleutian Island chain in Alaska, Central America, Japan and Indonesia have all been more active recently, Luhr said.


"The Aleutians are one of the most vigorous volcanic parts of North America," he said.





But he noted that other parts of the world have plenty of dormant volcanoes, including France and Germany.

Luhr recently returned from a trip to Armenia where ancient petroglyphs show evidence of eruptions.

"There are relatively young volcanoes all over Armenia," he said. "None have erupted in the last 4,000 years, but clearly ancient peoples have seen them."

There is a chance that other Northwest volcanoes could erupt. But like Mount St. Helens, it will probably be mostly rock and ash that spew forth, not the dramatic, fiery rivers of lava that accompany eruptions in Hawaii, scientists say.

Other volcanoes have taken a deadlier toll.

In January 2002, lava rolled down the slopes of the African volcano Mount Nyiragongo and flooded the streets of Goma, Congo, killing at least 75 people.

Some small news:

I think this may be the first time the French military has been used since Vietnam. I bet they're pretty rusty. :lol:

They need to start more arbitrary and unjustifiable wars to keep in shape. ;)

Well Kong Wen, I think they're luck has run dry since 1941. :D

France is more of the laid back type, they prefer to get their oil from diplomacy instead of invasion. :lol:

Touché.

And now back to our regular scheduled program. Related to Shortyafter's post only thematically, it looks like the US (er, I mean, "coalition") has been working on it's biggest organized war-type work in Fallujah for the last couple days. Perhaps the possible implications of this will be discussed in one of the threads devoted to Iraq.
