underwater restaurant in the maldives

Did you know there is a restaurant completely underwater? (This is the strangest thing I have heard about since the first ice hotel!)

The Ithaa Restaurant (Ithaa means “pearl” in the Maldives) is located 15 feet below the surface of the Indian Ocean, and is surrounded by a coral reef (article). It is part of the Hilton Maldives Resort & Spa Rangali Island and was built in April 2005. It must be a rare treat, since it can only fit 14 people at a time and costs $170 - $250 per person.

sony bravia 's exploding colors

Sitting around talking in San Francisco one evening, this guy brought up a Sony ad involving and a hilly San Francisco street and superballs. (I don't know if the ad runs in the U.S. ... As you know, I can't remember the last time I turned on a TV.) Intrigued, I wanted to learn more. These ads ended up being even more awesome than I imagined! (And done without computer graphics.) Sony's BRAVIA brand uses the slogan "Color like.no.other."

To announce the arrival of the BRAVIA LCD and 3LCD range, we wanted to get across a simple message - that the colour you'll see on these screens will be 'like no other'. - Bravia site

AMAZING / CRAZY COMMERCIAL #1: BALLS

So, the first commercial (filmed in 2005) features 250,000 superballs, a kid, and one frog. It took 23 people to film and "only one chance to get [the main sequence] right". With a combination of trucks and air cannons, the balls were released. Although pretty to look at, "these balls can do some damage, so all the cars were props and crew members went so far as to having protective shields and crash helmets."

Watch the BALLS commercial.

Read about the British soft drink's spoof of the ad.

AMAZING / CRAZY COMMERCIAL #2: PAINT

This one (July 2006) was filmed in Glasgow, Scotland and took 10 days, 250 people (to film), and 70,000 liters of paint. (The cleaning took 5 days and 60 people!) And of course, as in all experiments, "safety first."

Keeping everyone safe was also an important factor. A special kind of non-toxic paint was used that is safe enough to drink (it contains the same thickeners that are sometimes used in soups). It was also completely harmless to the skin.

If I watched TV, these ads might make me go buy one. :)

my first earthquake

This morning, at 4:42 am (PT), the U.S. Geological Survey reported that a 4.2-magnitude earthquake shook the San Francisco area. (read article) The quake originated about two miles east-northeast of Oakland, at a depth of 3.6 miles. Oakland is just east of San Francisco, across San Francisco Bay. I remember feeling my bed shake, waking up, and wondering if it was an earthquake. However, when I saw the clock said 4:44 am, I decided leave the investigating until the morning.

According to the USGS, "Each year the southern California area has about 10,000 earthquakes. Most of them are so small that they are not felt. Only several hundred are greater than magnitude 3.0, and only about 15-20 are greater than magnitude 4.0. " Although San Francisco is not exactly southern California, the general idea is the same. There are many microquakes each day, but this morning's quake was an unusual one. (In fact, according to the USGS site right now, in the 12.5 hours since this morning's quake, there already have been 11 more earthquakes in California today!)

Earthquakes, as most of you know, are a consequence of moving tectonic plates and are measured using the Richter scale.

The Richter scale is a standard scale used to compare earthquakes. It is a logarithmic scale, meaning that the numbers on the scale measure factors of 10. So, for example, an earthquake that measures 4.0 on the Richter scale is 10 times larger than one that measures 3.0. On the Richter scale, anything below 2.0 is undetectable to a normal person and is called a microquake. Microquakes occur constantly. Moderate earthquakes measure less than 6.0 or so on the Richter scale. Earthquakes measuring more than 6.0 can cause significant damage. The maximum quake rating ever measured is about 8.9. - HowStuffWorks

science across the usa

I haven't travelled much in my life, so it was a great "hands-on" opportunity to drive across the country this summer and experience earth science! I learned so much, and I would like to share one thing I learned from each of the amazing science sites I visited on my drive from Chicago to California. (All images are my own photos - feel free to click on any of them for a larger version.)

The Badlands (South Dakota) - This national park consists of nearly 244,000 acres of some of the most bizarre landforms I have ever seen. Here, rivers and rainstorms have been eroding away the soft sediments and volcanic ash, revealing colorful bands that correspond with specific time periods in the history of the rock formation.

Wind Cave (South Dakota) - First explored by a 16 year old boy with a candle and a string, Wind Cave now has over 100 miles of known passageways, although studies indicate only about 5% of the cave has been discovered.

The most fascinating part of the cave is its entrance. The Lakota Indians have been long aware of this opening, and regard it as a sacred place. In the picture to the left, you can see a guy attempting to enter the natural entrance of the cave. (I guess he didn't care about the gate park rangers have installed to stop people from doing just that....) It is this opening (and not the cave's interior) that gives Wind Cave its name.

The wind moves depending on atmospheric pressure on the surface and inside the cave. When the pressure is higher outside than inside the cave, wind rushes into the entrances; when pressure is higher inside the cave, the wind blows out of the entrances.

The wind is driven by changes in barometric pressure. The air pressure within the cave and outside attempt to reach equilibrium. The wind blows into the cave when the barometer rises, and out when the barometer falls. This airflow may forecast how the weather is going to change. - nps.gov

This was confirmed on our visit by the presence of ominous clouds in the distance (storm approaching) and the strong winds blowing out of the natural entrance.

Mammoth Site (South Dakota) - More than 26,000 years ago, many large Colombian and woolly mammoths spent their time tediously scraping away the snow with their tusks to find food. However, scientists believe some mammoths were "lazy" and were instead lured by the more easily-accessible vegetation at the sinkhole's edge. Once these mammoths risked coming near the sinkhole's edge, it is believed they fell in, became trapped and died.

Scientists have found remains of 52 mammoths in the pit (which was discovered by chance in 1974 when they bulldozed to make a housing development). Of those 52 animals, ALL of them are male. And all, except one, are young ADOLESCENT males. Raleigh Philip, author of an educational neuroscience text, says, "It's interesting to speculate how the young Colombian Mammoths' adolescent brain may have led to their demise in the same way that teenagers take risks today."

Devil's Tower (Wyoming) - Geologists agree that Devils Tower is the core of a volcano exposed after millions of years of erosion. However, there is still debate about the exact details of its formation. This bizarre land form has been somewhat of a mystery. Perhaps that is why Stephen Spielberg used Devil's Tower as an alien communication point in his movie Close Encounters of the Third Kind.

Also known as Bears Lodge, it is a sacred site for many American Indians. I personally like their legend the best.

In one story, two girls playing in the woods are chased by an enormous bear. The girls jump on top of a rock, but it is too small to give them safety. The Great Spirit sees the girls' predicament and causes the rock to grown to an immense size. The giant bear jumps at the girls, but cannot reach the top. His claws leave the gouges in the side of the rock that can still be seen today. - the Unmuseum

Beehive Geyser (Yellowstone Nat'l Park, Wyoming) - While Old Faithful is certainly the most famous geyser at Yellowstone, it is just one of the 10,000 geothermal features found in the park. The geyser in the picture is Beehive Geyser, an unpredictable cone geyser with water reaching 93 °C (199 °F) and eruptions up to 200 feet! A cool thing about this geyser is that there is a small vent located a few feet east of Beehive, called Beehive's Indicator, which erupts about 6 feet, 10-20 minutes before an eruption. When we walked by the sputtering indicator, we decided to stick around for the show!

Yellowstone Nat'l Park, (Wyoming) - Thermophiles, or microbes that live in extremely hot conditions, make up these colorful bacterial mats. Pigments (like chlorophyll and carotenoids) within the microbes are responsible for their colors. The run-off channel from a hot spring, for example, is white or clear near its source. This water is heated by the magma just under the earth's crust! Only a few single-cell bacteria live in this boiling water, which is 93 °C (199°F). (Pure water boils at 212°F at sea level.) As the water slightly cools to 167°F farther downstream, the first colorful forms of bacteria show up. Shades of green to pink to orange to yellow-brown to gray indicate bacteria growing in slightly different temperature regions on the mat.

(Yellowstone Nat'l Park, Wyoming) - At the Mammoth Hot Springs, I learned that these white tiered formations were travertine. This mineral is formed when hot water dissolves the limestone beneath Mammoth and brings it to the surface where it cools, and and forms this delicate mineral. These terraces (in the picture) are like "living sculptures," since they can change with changes in temperature, water flow, and bacterial concentrations. (Notice the colorful thermophile bacteria mat in the background.)

Mud Pots! (Yellowstone Nat'l Park, Wyoming) - I was somewhat familiar with hot springs before my Yellowstone trip, but I was was never introduced to their close cousins, the fumarole and the mudpot. The mudpots quickly became my favorite geothermal feature, mostly due to their "bloop bloop" sounds. A mudpot or paint pot is a sort of hot spring or fumarole consisting of a pool of usually bubbling mud. Watch my Quicktime video to see a mudpot hurling mud into the air.

Craters of the Moon (Idaho) - I saw fields of lava, both áa ("ay-ay") and pahoehoe ("pa-hoy-hoy") lava. (I liked the sound of those names!) The highlight of this visit had to be exploring the caves formed by the collapse of giant lava tubes. The tubes were originally formed as hot lava melted and rock in its path, while the surface of the lava in contact with the air hardened (forming the "roof" of the cave). When these tubes collapsed, they made great caves to explore!

Finally, I couldn't resist... this picture is one of my favorites from the trip. You don't see this in Chicago!
