Shanghai: The Layover

Shanghai MaglevOn our flight to Hanoi, we had a few hours at Pudong Airport.  Waiting for our flight to Hanoi, while traveling from Vancouver to Vietnam, we had a few hours in Pudong International Airport.  For something to do, we took the Maglev to check it out.  “What’s the Maglev?” you ask.

Shanghai Maglev 429kmh
At 429km/h it’s a little hard to hold the camera steady!

It’s a high-speed train propelled by magnetic levitation.  That’s science folks!  And, this train doesn’t just leisurely roll along, it moves at a speed of more than 430km/h.  That’s no typo…FOUR HUNDRED THIRTY! (FYI: Max speeds during testing were over 500km/h.)

It’s the World’s Fastest Train!

We made the 30km trip from Pudong International Airport into Shanghai in approximately 7 minutes.  Not too shabby for a commute that long.  Google maps estimated it would be about an hour by car.

For the layover in China on our way home from Bangkok to Vancouver, we opted to do some sight-seeing.

In the short few hours, the two of us visited Yuyuan Gardens, took photos of The Bund (from afar), and made it back to the airport in time for our flight home.

BKK Airport
Where’s Waldo of sorts. We’re waiting inline to check-in at BKK for the flight to Shanghai.

What do you do to break up the lengthy airport layovers?

Salmon Run

Salmon Run Adams RiverMid-September, I roped a friend into going to the Adam’s River Salmon Run. He really wasn’t keen on it. As someone who works on the Thompson and Fraser Rivers, he sees thousands of fish in the river each summer, and understandably didn’t want to go see more. Luckily, my persistence paid off, and we went for the mini road trip. Every 4 years there is a mass return to the spawning grounds; 2010 was supposed to be one of the biggest returns in the past 100 years, so why not check it out?

The Salmon Run was elementary school field trip extravaganza when we were little! We would have to learn all the stages of the life cycle. Here’s your science lesson just in case you don’t remember grade 2. The salmon swim from the Pacific Ocean, travel up the Fraser River through Hell’s Gate, up the Thompson River and into the Adam’s River where they spawn and die. (And, smell horribly bad!) The eggs hatch, grow, swim to the ocean, live there for a few years, and if they’re lucky to have survived that far, they swim back to the Adam’s River to start the cycle all over again.

We were there at the start of the Sockeye run and the very end of the Chinook run. The size difference between the two fish is crazy, but I wasn’t able to get any good photos of Chinook to compare. They don’t turn the bright pink colour that the Sockeye do. We wandered the trails, took a few photos and all in all had a fun little road trip.

Do Not Feed Prairie Dogs

Do not feed prairie dogsPrairie Dog Town is a real location at the entrance of the Belle Fourche campground. True story. Check out the map. We ended up spending a very rainy night there. The campground was nice enough, but the weather not so much. At least we were able to take some fun photos.

 These Black-tailed prairie dogs remind me of the marmots at one of the parks here. (photo below) Even though they’re Yellow-bellied marmots–they still look the similar. Yep, Groundhogs, Marmots, Prairie Dogs, whatever you like to call them–the same all over the place. (ps: they really are all from the Sciuridae family, so there’s your mini science lesson for the day.)

Devil’s Tower

Devil's TowerIn 1906, Devil’s Tower was proclaimed the first national monument by President Roosevelt. The tower is a crazy rock formation. From the pictures it doesn’t really look that big, but the top of the tower is about the size of a football field. Though it looks like an old volcano it isn’t.

The tower is actually an igneous intrusion (Science lesson: Magma pooled under sedimentary rock, it eventually hardened and then the sedimentary rock–being softer, eroded over time and exposed the igneous rock formation of the tower. Munson would be so proud of me remembering all of that from Geography!) Now this I had to use google for: “Devil’s Tower is made of Phonolite porphyry, it is similar in composition to granite but lacks quartz. Phonolite refers to the ringing of the rock when a small slab is struck, and its ability to reflect sound. Porphyry refers to its texture, large crystals of feldspar embedded in a mass of smaller crystals.”

Sad to say that the tower was pretty amazing, but this was probably one of the worst parts of the trip. We drove half way across the country so that Jon could climb at the tower and I could tour the park. But this was the only day of the whole trip that it wasn’t scorching hot. It RAINED so hard that there was no climbing to be had by anyone for the day we paid for, or the day after that. SO HORRIBLE! So, now Jon has a credit in Wyoming for the next time we happen to feel like driving over 2000km and back just for the weekend.

Yellowstone: Orange Mound Spring

Orange Mound SpringHere’s your science lesson for the day: Water deep below the surface of the earth is heated by the Yellowstone Volcano. The water bubbles to the surface, and flows out over the top of the Orange Mound. Calcium Carbonate and Travertine deposits left behind by the water create the formation. Some people we were talking to said that when they visited Orange Mound Spring a year earlier, it was much, much smaller. At this point, it is growing over the current road way, and work of moving the roadway to accommodate the formation has already begun.

Orange Mound Spring is only one of several examples that show the park is always in transition. Word is that no two visits to Yellowstone are ever the same.

Shrine of Guadalupe

On the way home from Peru, we had a 2 day stay in Mexico City. There were a few sites I wanted to see, but for some reason I was a little nervous about being there. The Metropolis that is Mexico is home to over 21 million people. It is the largest city in North America, so you can see why it would be a little intimidating! That said, we managed the metro, and navigating the bus system to everything we wanted to see.

Obviously the city is very old which brings along a lot of interesting, dingy, smelly places. The um, how to explain…aroma? of the City was olfactory assault in its highest art form. On certain streets, just walking around brought on an onslaught of odour. Seriously, I can’t even explain it. Surprisingly, the metro system was actually fairly clean. (At least we didn’t see the same amount of human feces on train cars in Mexico as we did in Paris!) There were sanitation people sweeping platforms and stairways 24/7.

The touts were inescapable, but at least humourous on the metro. People would hop on trying to sell literally everything and anything. We were offered crossword puzzle books, ancient computer repair manuals, rulers, CD’s, and my personal favourite–back scratchers.

While in Mexico, we visited the pyramids at Teotihuacan and Templo Mayor as mentioned previously. We climbed the Pyramid of the Sun. (FYI: It is the 3rd largest pyramid in the world.) I didn’t include photos earlier; here they are now.

When we arrived at Teotihuacan there was an insane performance going on. Thanks to Google, I now know that it is called the Danza de los Voladores de Papantla. The geek in me loves that the ceremony is recognized by UNESCO as Intangible Cultural Heritage.

We also went to the Shrine of Guadalupe. The history of the shrine is similar to that of the Orvieto Duomo. To shorten up the lesson for you–in 1531 a catholic peasant had a vision of the Virgin Mary. She told him to build a church where she was standing so that she could offer love, compassion and protection to the people. The peasant, Juan Diego, spoke to the Bishop. The Bishop didn’t believe him and wanted some miraculous proof.

The Virgin appeared to Juan Diego again, and told him to pick flowers and gather them in his apron. Though it was winter, the flowers grew at his feet, he gathered them and went to the Bishop. An image of the Virgin Mary was imprinted on the apron. Thus, providing the miracle the Bishop wanted and the rest is history.

The Shrine of Guadalupe is the most visited Catholic Shrine in the world. The original basilica that was completed in 1536 is beautiful. There is a new basilica on the site as well. It is kind of gaudy, round shaped, and looks like it should for a building of the late 1970’s. We didn’t enter the new basilica to see the actual apron, or tilma on display above the alter. Church service was going on, and out of respect we stayed out. I was surprised how few people were at the site as I was expecting more visible pilgrimage that I’ve seen elsewhere (e.g.: people crawling or on their knees in hopes that their prayers would be answered.) Still, a site of such importance for so many people is humbling.

Now for science: The cloth has been examined with infrared photography, ultraviolet imaging, and stereo-microscopy. The earliest analysis shows that no under-drawing to rough out the image and no over-varnish on the image. The latter 2 show several layers beneath the current painting with all sorts of different pigments consistent with artist’s materials used in the 1500’s. There are also cracks, flaking of paint and sketch lines that would make it seem that the image was sketched before being painted.

Even with all the scientific analysis to create doubts of the miracle, the tilma still has some pretty impressive attributes. Thanks Wikipedia for the info.

The tilma has maintained its structural integrity over nearly 500 years, while replicas normally last only about 15 years before suffering degradation; it repaired itself with no external help after a 1791 ammonia spill that did considerable damage, and in 1926 an anarchist bomb destroyed the altar, but left the icon unharmed.

In 1929 and 1951 photographers found a figure reflected in the Virgin’s eyes; upon inspection they said that the reflection was tripled in what is called the Purkinje effect, commonly found in human eyes. An ophthalmologist, Dr. Jose Aste Tonsmann, later enlarged an image of the Virgin’s eyes by 2500x and found not only the aforementioned single figure, but images of all the witnesses present when the tilma was first revealed before Zumaragga in 1531, plus a small family group of mother, father, and a group of children, in the center of the Virgin’s eyes, fourteen persons in all.

Numerous Catholic websites repeat an unsourced claim that in 1936 biochemist Richard Kuhn analyzed a sample of the fabric and announced that the pigments used were from no known source, whether animal, mineral or vegetable. Dr. Philip Serna Callahan, who photographed the icon under infrared light, discovered from his photographs that portions of the face, hands, robe, and mantle had been painted in one step, with no sketches or corrections and no visible brush strokes.

I have no doubt that there is paint on the image–whether the miraculous image itself has been painted upon over the years, or painted completely is debatable, but you have to admit that the eyeball thing is a little bizarre.

ps: Our Lady of Guadalupe is the patron saint of Mexico. Juan Diego was also made a saint in 2002. He’s the first Mexican to achieve sainthood.

 

Panthéon

The Panthéon, Paris France

The first Panthéon of the trip was in Paris. The second in Rome. Both awesome!

When we arrived, the Panthéon had just closed for the day, but the sun was shining which made for some alright exterior photos. I knew it wasn’t an option to miss out on seeing the inside, so we made a point of going back.  If you’re in Paris, check it out.  You won’t be disappointed.

The Panthéon made me feel very insignificant for several reasons. The size of the building itself is magnificent. There are incredible figures buried in the necropolis–famous authors, philosophers, and scientists. The likes of Victor Hugo, Voltaire and Marie Curie to name a few. To see their tombs was both unnerving and enchanting at the same time. And then, you have Foucault’s Pendulum which is fascinating.

Foucault's Pendulum, Paris FranceFoucault’s Pendulum shows the rotation of the Earth as the pendulum swings. I’m no physics buff, so I won’t try to explain the science behind it. You do your own research!

I’ve have a short video clip I took when we were there. You can tell it was between noon and 1:00pm simply by how the pendulum swings.

“In 1851 it was well known that the Earth rotated: observation evidence included Earth’s measured polar flattening and equatorial bulge. However, Foucault’s pendulum was the first dynamic proof of the rotation in an easy-to-see experiment, and it created a sensation in the academic world and society at large.” (Thanks Wikipedia!)

Orvieto Duomo

Orvieto DuomoWe went to A LOT of churches on the trip. Most were absolutely amazing, but none were quite as fanciful as the Orvieto Duomo (at least on the outside–clearly St. Peter’s Basilica is way fancier on the inside!).

Wikipedia has some learning for you. Abridged version–the Duomo is very glittery; when the sun shines on the front it is gorgeous. Story goes, that in Bolsena, Italy, a traveling priest doubted the transubstantiation as occurs in the Eucharist. His Host began bleeding, bled more, and stained the alter cloth. Upon seeing this miracle, the priest’s faith was restored. This alter cloth is now stored in the Duomo. During Corpus Christi celebrations, the Corporal of Bolsena is displayed on parade around the city.

Now after this Catechism lesson, here’s for the science believers! (Straight from Wikipedia, so you know it is true!)

It is only within the last ten years that the Academies of Science would not have been sorely puzzled to explain so strange a phenomenon. Now, no one thinks of denying it, since the discovery of a microscopic fungus, the spores of which having germinated in the meal or dough, offer the appearance of clotted blood.
Le Jardin de l’Epicure, Anatole France
Orvieto was exactly what we needed after the horrible experience we had in Venice. There was so much to do and see in such a little place. We toured the Orvieto underground, went to St. Patrick’s Well, shopped, had amazing gelato, and a fantastic hotel room. If you’re going to Italy–stopping in Orvieto is a must!
