Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar.

Honours and legacy In 1929, Soviet writer Leonid Grossman published a novel The d'Archiac Papers, telling the story of Pushkin's death from the perspective of a French diplomat, being a participant and a witness of the fatal duel. The book describes him as a liberal and a victim of the Tsarist regime. In Poland the book was published under the title Death of the Poet. In 1937, the town of Tsarskoye Selo was renamed Pushkin in his honour. There are several museums in Russia dedicated to Pushkin, including two in Moscow, one in Saint Petersburg, and a large complex in Mikhaylovskoye. Pushkin's death was portrayed in the 2006 biographical film Pushkin: The Last Duel. The film was directed by Natalya Bondarchuk. Pushkin was portrayed onscreen by Sergei Bezrukov. The Pushkin Trust was established in 1987 by the Duchess of Abercorn to commemorate the creative legacy and spirit of her ancestor and to release the creativity and imagination of the children of Ireland by providing them with opportunities to communicate their thoughts, feelings and experiences. A minor planet, 2208 Pushkin, discovered in 1977 by Soviet astronomer Nikolai Stepanovich Chernykh, is named after him. A crater on Mercury is also named in his honour. MS Alexandr Pushkin, second ship of the Russian Ivan Franko class (also referred to as "poet" or "writer" class). Station of Tashkent metro was named in his honour. The Pushkin Hills and Pushkin Lake were named in his honour in Ben Nevis Township, Cochrane District, in Ontario, Canada.

Rough surfaces create more friction than smooth surfaces. Thats why cars have tires. Its also why we use rubber mats in areas that might get wet. In your bathtub, you may even use No-Slip tape. No-slip is another way of saying the items has a lot of friction. In Figure 1.9, the blades of the skates are very smooth. Thats why you cant slide across ice with shoes. The soles of your shoes are much rougher than skates. The rougher surface of shoes causes more friction and slows you down. Heavier objects also have more friction. A heavy object presses down with more force. The surfaces are held together more tightly. This makes the surfaces harder to slide past each other. Did you ever try to push something heavy across the floor? Heavy objects are much harder to push than light objects.

The White Rajahs of Borneo: In the 19th century, Borneo remained relatively undeveloped. Balanini pirates, fervent Muslims, disputed the coast of northeastern Borneo (modern Sabah) with the sultanate of Brunei. Sarawak's coast and jungle interior were controlled by the IbanSea Dayak pirates and Land Dayak slash-and-burn farmers. (The Dayaks practiced head-hunting, a ritual that was believed to bring spiritual energy to their communities. ) The region was unproductive and without great resources, except for the Sarawak river valley, where the Chinese mined for gold and antimony. Brunei chiefs traded the metals through Americans in Singapore. In 1839, the governor of Singapore sent James Brooke (18031868) to promote trade links with the Sultan of Brunei. He had been an audacious cavalry officer in the Anglo-Burmese wars and now exploited the situation for his own benefit. In exchange for helping the regent end a revolt of uppity Malay chiefs, Brooke was made Rajah of Sarawak in 1841, with his capital in Kuching (founded by the Malays just 11 years earlier). He tried to halt the Dayaks' piracy and head-hunting while defending their more "morally acceptable" customs. His attempts to limit the opium trade met with resistance by the Chinese in Bau, who revolted. His counter-attack with Dayak warriors drove the Chinese out of Bau and across the Sarawak border. Thereafter, Chinese settlement was discouraged and did not achieve the commercial dominance it enjoyed on the peninsula. In 1863, Brooke retired to Britain, handing Sarawak over to his nephew Charles. More reserved and remote but a better administrator and financier than his uncle, Charles Brooke imposed on his men his own austere, efficient style of life. He brought Dayak leaders onto his ruling council but favored the time-honored colonial practice of divide-and-rule by pitting one tribe against another to keep the peace. Northeast Borneo (Sabah) was "rented" from the Sultan of Brunei by British businessman Alfred Dent. Dent was operating a royal charter for the British North Borneo Companya charter similar to that of the EIC.
