from 1930-34 visiting scientist at Harvard University. 3. Öpik was one of the most outstanding astrophysicists of his generation, with wide- ranging interests in the physical sciences. Among his many pioneering discoveries were:the first computation of the density of a degenerate body, named the white dwarf; the first accurate determination of the distance of an extragalactic object (Andromeda Nebula;the prediction of the existence of a cloud of cometary bodies encircling the Solar System, later known as the "Oort Cloud";the first composite theoretical models of dwarf stars like the Sun which showed how they evolve into giants;a new theory of the origin of the Ice Ages. 4. Öpik made many contributions to our knowledge of the minor bodies of the Solar System and founded the meteor research group at Harvard. His statistical studies of Earth-crossing comets and asteroids are fundamental to our understanding of the

They also chopped their opponents in battle and it was considered a sign of prowess and social standing to have a goodly number of heads to display.

From there the Malay people spread across archipelago and introduced the game in Sulawesi. There the game developed further and became Buginese traditional game which is called "Raga”. Some men playing "Raga" encircling within a group, the ball is passed from one to another and the man who kicked the ball highest is the winner. The modern version of sepak takraw began taking shape in Thailand during the early 1740s. In 1829 the Siam Sports Association drafted the first rules for takraw competition.] Four years later, the association introduced the volleyball-style net and held the first public contest.

Generally speaking these two districts are now collectively referred as the Old Town. The Town wall and towers Medieval fortresses, which emerged during the development of the medieval town at the end of the 13th century, surrounded the city centre as a closed defence zone. By the 16th century, Tallinn's defence system was one of the most powerful in Northern Europe. The city wall was three meters thick, sixteen meters high, and four kilometres long, completely encircling the city with 46 defence towers. The portion of the wall that has survived is two kilometres long, encompassing 26 of the original towers. Three towers and a section of the town wall surrounding the Old Town are open to the public and can be visited by anyone with a sense of adventure. Tallinn Old Town is changing fast with widespread renovations, but it has kept its charm. Many of the 26 towers that still stand now house cafes and museums.
Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool.

The church organ, built in Germany in the 19th century, is one of few in Europe today with a specific romantic sound. Nowadays, the church has an Estonian Lutheran congregation and also serves as a concert hall. 3. Lower Town The Town Wall encircling the Lower Town is one of the greatest medieval treasures of Tallinn. It was begun in the 13th century, completed in the 14th and constantly improved and strengthened thereafter. The walls were 2.5 metres thick on average, over 2 km long, and their height reached 15-16 metres. The wall was fortified by 27 towers, 18 of which have survived. In Tower Square you can admire several of them. The strongest are the cannon towers Fat Margaret and Kiek in the Kök (Peep into the Kitchen)
depths. These were Germany's transatlantic cables, her chief communications lifelines to the world, and the vessel was the British cable ship Telconia. Though the Committee of Imperial Defence never dreamed of it when it planned the move in 1912, the cutting of these cables, England's first offensive action of the war, forged the first link in a chain that helped to end it. Germany was now forced to communicate with the World beyond the encircling Entente by radio or over cables controlled by her enemies. She thus delivered into the hands of her foes her most secret and confidential plans, provided only that they could remove the jacket of code and cipher in which Germany had encased them. It Was an opportunity for which England was unprepared, but of which she promptly availed herself. On that first day of the war, the director of naval intelligence, Rear Admiral Henry F. Oliver, walked to lunch With the only man at the
