Fastest trains in the world

There are trains which are the fastest. Some of them are noted because they are the largest. Some trains do not fall into any of these categories but are known to carry the largest number of passengers. Newer versions of such super fast trains have started making their appearance around the length and breadth of several countries. They have made travel faster and easier for human beings. The following is the list of the fastest trains in the world!

1. CRH2 of China
The CRH2 is a modified E 2-1000 series Shinkansen design and is one among the fastest train models in China. It is also the second Shinkansen model of train that was exported. The other one was the 700T series.

The world's largest teak mansion

Yes it's true, Bangkok has the world's largest Teak Mansion. Now I know what you're thinking. #1 "What the hell is Teak?" #2 "Ok, and....?". Here are my answers to you, which I learned while at the Teak Mansion. Teak was a very valuable type of wood for the Thai people, and rich people would build their whole houses with it, now it is illegal to cut down trees in Thailand, so occassionaly wealthy will import Teak to build there house with it. In days of old people in Thailand would build traditional houses using teak and without the assistance of any nail or bolt. So with that background info here are my recommendations for this site:#1 - Go into this knowing that it's really not terribly interesting unless you love antiques (which decorate the house) or teak. If you are a teak fanatic I may wonder about how this came about, but antiques I can understand, and the house is full of them#2 - Photography is not allowed. You must lock all you possessions in a locker prior to entering and may not wear shoes.#3 - You are supposed to go with a guide. Which means you have to learn about every room and chair and candlestick in the place, which can take an hour and prove to be infinately boring. Sometimes you have to wait for 20-30 minutes for a guide who speaks your langauge, forcing you to wait outside in the sun, when all you want to do is move on to another attraction in Bangkok. #4 - If you are clever enough you can sneak into the house and go on your own. This makes the house exciting because not only are you in the biggest Teak mansion in the world, you have to duck away from guards and security and so forth. In actuality, sneaking off on your own may be your only thrill provided by the mansion! You may get an additional kick out of catching up to a group from Japan or Thailand and be the only 6 foot tall plus white guys in the group. Just act like you belong and hang out and see the looks on their faces. Good times#5 - In reality, Teak Mansion, for me, did not exactly put the air in my sail. I could have gone without it and instead have seen a different sight. However maybe I will be able to use the "Oh yeah well I've been to the worlds biggest Teakwood Mansion" one day as bragging rights

Latest news given by NASA ABOUT Mt.Etna

Renewed activity at Europe's largest volcano sent ash into the atmosphere and lava flowing down its slopes.  The display by Mount Etna on the island of Sicily was captured in imagery taken by NASA's Terra satellite.
The image, released by NASA today, was taken on January 11th as the mountain began spewing ash but before the lava began flowing.  Click on the image to the left to view the satellite photo.
Increased seismic activity led seismologists and volcanologists to believe an event was going to happen and on January 12th Etna came to life.  The impressive eruption was captured in astounding video taken by residents.
The 10,925 foot tall Etna has a long and storied past dating back to 1500 BC.  The Global Volcanism Program documents a regular and near constant history of eruptions, some of which have caused destruction and death.
Mt. Etna’s largest eruption occurred on March 11, 1669 and sent flowing lava down its slopes that buried parts of the city of Catania and killed an estimated 15,000 people.
Since that time only one other eruption of the mountain has caused destruction.  That event, on November 2, 1928, virtually destroyed the village of Mascali.  Many other sizeable eruptions have occurred but population centers have luckily escaped devastation.

Check out this puzzle

An easy technique for solving sliding-tile puzzles.
I've hated these puzzles my entire life. It seemed like no matter what I did there always ended up being one tile out of position and to get it where it had to go I had to scramble all the pieces that had taken so much effort to get into place. It got so that I hated even looking at these things.
Then one day I decided that I didn't want to die without having mastered this demon. Internet searches turned up many sites that presented elaborate mathematical theories on their solutions and several that offered programs that solved them, but none explained how to do it manually. So, I purchased a 15-puzzle, sat down with it, took out a pencil and graph paper and dug in for the battle.
Two days later I not only solved it but developed a simple technique anyone can learn to solve their 15-puzzles. This page shows this technique. If you've been haunted by these monsters of the puzzle realm, then this page will help you conquer them.
The goal is to get all the numbers to line up in order from left to right and top to bottom like this:
Let's begin by taking a second look at the scrambled puzzle shown at the top of this page:
Start by moving tiles around any way you want to get the empty space between the 1 and the upper left corner.
Slide the 1 up into this empty space to move it closer to the upper left corner.
Repeat as often as needed until the 1 is in the upper left corner. Don't worry about any other tiles at this point.
Repeat this process with the 2, 3 and 4 to get them in order along the top row.
Once in a while things work out so you can slide the 4 into the upper right corner. If it does, great... you got lucky. More often than not you'll end up with a nightmare like the following:
The trick to figuring out how to get the 13 out of the corner and the 4 up into it is the key to solving 15 puzzles. Fortunately, it's an easy trick to learn.
The 1, 2 and 3 tiles can be moved down and around the corner as shown by the arrows in the picture below so that their order isn't disturbed. Later, they can be moved back into place.
Slide the 9, 7 and 6 one space to the right and the 8 down. This opens up a space below the 1. Move the 1 down and the 2 and 3 to the left. You get the following:
Note that even though the 1, 2 and 3 are bent around a corner, they are still in order. Now, without touching them, rotate the 13, 4 and 10 tiles counter clockwise until the 4 is in the upper right corner and there is an empty space on its left. Now move the 3, 2 and 1 tiles back into place like this:
...and your top row is complete!
This trick of moving tiles while keeping them in order to create an opening where you need it is the key to solving 15-puzzles.
Once the first row is done we forget about it and use the simple tile-moving technique used to get the 1, 2 and 3 tiles into their places to get the 5, 6 and 7 tiles in order along the second row.
Just as we had with the 4, the place where the 8 is supposed to go is filled and there is no empty space close to it. The solution is to repeat the in-order temporary shift used to complete the top row. Start by moving the tiles in the bottom row to the right, then the 5 down and the 6 and 7 to the left to get this:
Take a look at the 5, 6 and 7. Just like with the top row they are still in order, they're just temporarily parked around the corner to get them out of the way.
As with the 4, rotate the 11, 8 and 14 tiles until the 8 is where you want it and then slide the 7, 6 and 5 tiles back into place.
Two rows done!
As it happened, the 9 ended up sitting where it needed to be. If it hadn't been there, I would have simply slid the bottom 8 tiles around until it was.
Now we need to move the 10 next to the 9. It looks tough because since we don't want to touch the top two rows we don't have much maneuvering room. Don't worry, simply move the 15 to the left and slide the 12, 11, 14, 10 and 13 tiles around in a sort of rotational pattern until the 10 is next to the 9.
To get the 11 next to the 10 just rotate the 13, 11 and 12 tiles clockwise.
Now things get a little more interesting.
At first this would appear to be an impossible situation because tiles are at opposite ends of where they are supposed to be and because there is so little maneuvering room. The solution is to employ the same trick we used to get the 4 and 8 into their spots: create an empty space near the target tile by temporarily moving other tiles "in order" out of the way. Some times at this late stage of solving a 15 puzzle the exact same technique can be used to finish it off. In this particular case things are a little more complicated so we have to modify the process a little.
First, start as before by moving the 12, 14 and 15 tiles to the right. Then slide the 9 down and the 10 and 11 to the left.
Now we are free to rotate the positions of the 13, 12 and 14 tiles so the 12 is in position next to the 11.
Then slide the 12, 11, 10 and 9 tiles back into place and the third row is done.
Now things really look hopeless. Fear not. We're almost done. This is where we modify the basic move-tiles-in-order-temporarily-out-of-the-way technique: we cut it in half.
Rather than moving the first three tiles in the third row down and over to get them out of the way, we only do it with the 9 and 10 to get the following after moving the 15 up into the 10's spot:
Next we do the same thing with the right half of the third row but this time we go down and across to the right. First the 13 and 14 are slid to the left.
Then the 12, 11 and 15 are moved over and down around the corner. Note that the 11 and 12 are still in their proper order.
Do you see the solution?
Move the 10 and 9 back into their proper places, then the 13 and 14 to the left.
Next slide the 15 down and the 11 left and 12 up to get them back into their positions.
And the puzzle is solved!
Once again, the trick to solving any of these puzzles is simply to realize that tiles can be moved out of the way while their order is retained to create elbow room where you need it to move other tiles around. Then the first tiles can be moved back and they will still be in order.
Although the photos on this page only show how to use this technique to solve a single puzzle, I've used the same trick to solve dozens of different ones and it always works. The only tricky part is that sometimes you have to split the in-order temporary shifting in two steps at the very end.
There's one final trick that may save you a little time on some puzzles. Before plowing the 1 through the center of the puzzle to get it in the upper left hand corner, take a look at how the tiles lay. In the case below the 15 and 1 are in opposite corners. Rotating all the outside tiles around does two things at once: it gets the 1 into its corner and moves the 15 down close to where it needs to be.
In this particular case it also gives you the entire top row free of charge. Careful and creative examination of an initial puzzle may suggest similar time-saving moves.
