Modular origami (also called unit origami) is a type of paperfolding that uses many sheets of paper. Modular origami is used to make large structures that cannot be made with one sheet of paper. Many sheets of paper are folded in identical shapes, and they are then put together by inserting flaps into pockets.
The first modular origami model comes from a 1734 Japanese book by Hayato Ohoka called "Ranma Zushiki". The book has pictures of many traditional origami models, and one is a modular cube called "tamatebako". "Tamatebako" is a Japanese word meaning "magic treasure box", and it is called this because the box can be opened on any side. Another traditional model, kusudamas, are balls of folded paper flowers. They are often hung as decorations using string or thread.
The various number of modules is combined from two to tens of thousands modules. When modules are put together, most are supported only by the friction of paper, also they are glued together or sewn by threads.
Mitsunobu Sonobe designed in 1970s. It is so simple that most people can make kusudamas. Module of Sonobe method is one of the most famous modules. We can make a polyhedron like a cube or a trisoctahedron(a dodecahedron?) by putting together many modules.
Modular Rate is the facility of putting together. This rate is how many people can put together without joining materials like glues. This rate applies the model that was designed so that it was put together without using joining materials from the beginning.
University of Missouri
The University of Missouri (often shortened to MU, and also nicknamed Mizzou) is a public university in Columbia, Missouri, in the United States that was started in 1839. It has about 31,000 students.
Missouri's athletics teams are called the Tigers. Missouri has 18 varsity teams that now compete in the Southeastern Conference. The school's mascot, Truman the Tiger, is named after President Harry Truman, who was from Missouri.
There are more than 280 degree programs at the University of Missouri.
The university's well known school of journalism is the oldest university journalism program in the United States. The school has awarded its Honor Medal for Distinguished Service in Journalism. The medal has been awarded yearly since 1930.
Saltasaurus
Saltasaurus was a large plant-eating dinosaur with an elongated neck and bony armored plates on its body. It was a titanosaurid sauropod which lived during the late Cretaceous period, about 83 to 79 million years ago. Fossils have been found in Argentina.
It was the first genus of sauropod known to have armour of bony plates embedded in its skin. The small bony plates (called osteoderms, a feature of modern crocodiles) have since been found on other titanosaurs.
"Saltasaurus" was named by paleontologists José Bonaparte and Jamie Powell in 1980. Salta is the name of the Northwestern Argentinian Province where fossils were found. They include: a few oval and circular armored plates, hundreds of bumps which covered its back (roughly 1/4 inch = 6-7 mm in diameter), and several incomplete skeletons, including some vertebrae, limb bones, and jaws.

Fiddler crab
A fiddler crab, also called a calling crab, is a land crab that lives in mud or sand flats near the beach. The reason this crab is called a fiddler crab is because it holds its large cheliped in front of its body and moves it back and forth as if it is playing a fiddle.
The male fiddler crab has one huge cheliped and another smaller cheliped. Sometimes it's the right cheliped that's the big one and sometimes it's the left. If a male loses its large cheliped, the smaller one will grow large to replace it. This huge cheliped is so large that it is sometimes bigger than the whole crab. It is this cheliped they wave back and forth.
The fiddler crab eats by first opening its mouth, then using its maxillipeds (a part of its mouth), it scoops in a small amount of mud or sand, depending on where it lives. Then, it uses its other mouthparts to scrape any food matter (algae, decaying animals or plants)it can from the dirt it has just put into its mouth. After this, it forms the mud or sand into a little pellet, which is called a "feeding pellet". It then drops the feeding pellet and starts all over again.
The reason the male fiddler crab has such a big claw is to attract females. Every two weeks during the summer, male fiddler crabs build little round burrows, which are deeper and better than the ones they usually build. The crabs guard these burrows fiercely. Where there are lots of fiddler crabs, there are usually hundreds of these little burrows all lined up only a few inches apart. Each male fiddler crab stands out in front of his burrow waiting for the females to return from eating. The females then walk around looking at the different burrows. As they walk past, the males wave their big chelipeds back and forth. If a female likes a male or burrow, she will stop and stare. Then the male begins waving his cheliped wildly. Sometimes the female will run away. However, if she stays, the male will run between her and the burrow, back and forth, again and again. If she has still not run away, she will come closer to the burrow. Then the male will enter the burrow a little and start drumming against the side of the tunnel with his cheliped. If the female likes what she hears, she will go down into the burrow, and they will mate.
Night
Night or nighttime is the time when the Sun is not in the sky. Night happens after dusk and before dawn. The opposite of night is day. The start and end times of night are different in different geographic locations. It varies on season, latitude, longitude and timezone.
In other time zones, the night occurs at different times. This is because the Sun shines on different parts of the Earth at different times. During a solar eclipse it is also partially night because the Sun is blocked out by the Moon.
In popular culture, night is often thought of as a symbol of evil, possibly because of the fear of the dark or possibly because of the lack of visibility.
Bureau of Economic Analysis
The Bureau of Economic Analysis (BEA) is an agency in the United States Department of Commerce that has economic statistics like the gross domestic product of the United States. Its stated mission is to "promote a better understanding of the U.S. economy by having the most timely, relevant, and accurate economic data in an objective and cost-effective manner."
Flag of Washington
The Flag of Washington has the state seal (which has an image of George Washington) on a field of dark green with gold fringe being optional. It is the only U.S. state flag with a field of green as well as the only state flag with the image of an American president.
