ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@Question 1-8 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ With Robert Laurent and William Zorach, direct carving ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ enters into the story of modern sculpture in the United States. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Direct carving - in which the sculptors themselves carve stone ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ or wood with mallet and chisel - must be recognized as someÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ -thing more than just a technique. Implicit in it is an aesthetic ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ principle as well: that the medium has certain qualities of beauty ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ and expressiveness with which sculptors must bring their ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ own aesthetic sensibilities into harmony. For example, some-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ times the shape or veining in a piece of stone or wood suggests, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ perhaps even dictates, not only the ultimate form, but ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ even the subject matter. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ The technique of direct carving was a break with the nineteenth-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ century tradition in which the making of a clay model ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ was considered the creative act and the work was then turned ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ over to studio assistants to be cast in plaster or bronze or carved ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ in marble. Neoclassical sculptors seldom held a mallet or chisel ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ in their own hands, readily conceding that the assistants they ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ employed were far better than they were at carving the finished ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ marble. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ With the turn-of-the-century Crafts movement and the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ discovery of nontraditional sources of inspiration, such as ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ wooden African figures and masks, there arose a new urge for ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ hands-on, personal execution of art and an interaction with the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ medium. Even as early as the 1880's and 1890's, nonconformist ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ European artists were attempting direct carving. By ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ the second decade of the twentieth century, Americans - ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Laurent and Zorach most notably - had adopted it as their primary ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ means of working. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Born in France, Robert Laurent(1890-1970) was a prodigy ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ who received his education in the United States. In 1905 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ he was sent to Paris as an apprentice to an art dealer, and in ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ the years that followed he witnessed the birth of Cubism, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ discovered primitive art, and learned the techniques of wood-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ carving from a frame maker. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Back in New York City by 1910, Laurent began carving ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ pieces such as The Priestess, which reveals his fascination with ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ African, pre-Columbian, and South Pacific art. Taking a walnut ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ plank, the sculptor carved the expressive, stylized design.ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ It is one of the earliest examples of direct carving in American ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ sculpture. The plank's form dictated the rigidly frontal view ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ and the low relief. Even its irregular shape must have appealed ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ to Laurent as a break with a long-standing tradition that ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ required a sculptor to work within a perfect rectangle or square. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 1. The word "medium" in line 5 could be used to refer to ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) stone or wood ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) mallet and chisel ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) technique ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) principle ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 2. What is one of the fundamental principles of direct carving? ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) A sculptor must work with talented assistants. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) The subject of a sculpture should be derived from classical stories. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) The material is an important element in a sculpture. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) Designing a sculpture is a more creative activity than carving it.

How does direct carving differ from the nineteenth-century tradition of sculpture? ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) Sculptors are personally involved in the carving of a piece. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) Sculptors find their inspiration in neoclassical sources. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) Sculptors have replaced the mallet and chisel with other tools. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) Sculptors receive more formal training. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 5. The word "witnessed" in line 23 is closest in meaning to ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) influenced ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) studied ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) validated ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) observed ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 6.

ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 7. The phrase "a break with" in line 30 is closest in meaning to ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) a destruction of ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) a departure from ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) a collapse of ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) a solution to ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 8. The piece titled The Priestess has all of the following characteristics EXCEPT: ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) The design is stylized. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) It is made of marble. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) The carving is not deep. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) It depicts the front of a person. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Question 9-19 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Birds that feed in flocks commonly retire together into ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ roosts. The reasons for roosting communally are not always ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ obvious, but there are some likely benefits. In winter especially,ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ it is important for birds to keep warm at night and conserve ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ precious food reserves. One way to do this is to find a ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ sheltered roost. Solitary roosters shelter in dense vegetation or ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ enter a cavity - horned larks dig holes in the ground and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ptarmigan burrow into snow banks - but the effect of sheltering ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ is magnified by several birds huddling together in the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ roosts, as wrens, swifts, brown creepers, bluebirds, and anisÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ do. Body contact reduces the surface area exposed to the cold ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ air, so the birds keep each other warm. Two kinglets huddling ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ together were found to reduce their heat losses by a quarter ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ and three together saved a third of their heat. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ The second possible benefit of communal roosts is that ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ they act as "information centers." During the day, parties of ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ birds will have spread out to forage over a very large area. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ When they return in the evening some will have fed well, but ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ others may have found little to eat. Some investigators have ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ observed that when the birds set out again next morning, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ those birds that did not feed well on the previous day appear to ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ follow those that did. The behavior of common and lesser ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ kestrels may illustrate different feeding behaviors of similar ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ birds with different roosting habits. The common kestrel ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ hunts vertebrate animals in a small, familiar hunting ground, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ whereas the very similar lesser kestrel feeds on insects overa ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ large area. The common kestrel roosts and hunts alone, but ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ the lesser kestrel roosts and hunts in flocks, possibly so one ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ bird can learn from others where to find insect swarms. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Finally, there is safety in numbers at communal roosts ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ since there will always be a few birds awake at any given ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ moment to give the alarm. But this increased protection is partially ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ counteracted by the fact that mass roosts attract predators and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ are especially vulnerable if they are on the ground. Even those ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ in trees can be attacked by birds of prey. The birds on the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ edge are at greatest risk since predators find it easier to catch ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ small birds perching at the margins of the roost. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 9. What does the passage mainly discuss? ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (A) How birds find and store food. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (B) How birds maintain body heat in the winter. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (C) Why birds need to establish territory. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ (D) Why some species of birds nest together. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 10.

But in 1810 a French ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ inventor named Nicolas Appert developed the cooking-and-sealingÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ process of canning. And in the 1850's an American ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ named Gail Borden developed a means of condensing and preserving ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ milk. Canned goods and condensed milk became more ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ common during the 1860's, but supplies remained low because ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ cans had to be made by hand. By 1880, however, inventors ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ had fashioned stamping and soldering machines that mass-produced ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ cans from tinplate. Suddenly all kinds of food could be ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ preserved and bought at all times of the year. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Other trends and inventions had also helped make it possible ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ for Americans to vary their daily diets. Growing urban ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ populations created demand that encouraged fruit and vegetable ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ farmers to raise more produce. Railroad refrigerator cars ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ enabled growers and meat packers to ship perishables great ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ distances and to preserve them for longer periods. Thus, by the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ 1890's, northern city dwellers could enjoy southern and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ western strawberries, grapes, and tomatoes, previously available ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ for a month at most, for up to six months of the year. In ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ addition, increased use of iceboxes enabled families to store ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ perishables. An easy means of producing ice commercially had ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ been invented I the 1870's, and by 1900 the nation had ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ more than two thousand commercial ice plants, most of which ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ made home deliveries. The icebox became a fixture in most ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ homes and remained so until the mechanized refrigerator ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ replaced it in the 1920's and 1930's. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Almost everyone now had a more diversified diet. Some ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ people continued to eat mainly foods that were heavy in starches ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ or carbohydrates, and not everyone could afford meat.

ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Biologists long regarded it as an example of adaptation by ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ natural selection, but for physicists it bordered on the miraculous. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Newton's laws of motion assume that the total amount of spin ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ of a body cannot change unless an external torque speeds it up ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ or slows it down. If a cat has no spin when it is released and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ experiences no external torque, it ought not to be able to twist ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ around as it falls. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ In the speed of its execution, the righting of a tumbling ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ cat resembles a magician's trick. The gyrations of the cat in ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ midair are too fast for the human eye to follow, so the process ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ is obscured. Either the eye must be speeded up, or the cat's ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ fall slowed down for the phenomenon to be observed. A century ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ago the former was accomplished by means of high-speed ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ photography using equipment now available in any pharmacy. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ But in the nineteenth century the capture on film of a falling ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ cat constituted a scientific experiment. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ The experiment was described in a paper presented to the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Paris Academy in 1894.

Grainy and quaint ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ though they are, the photos show that the cat was dropped ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ upside down, with no initial spin, and still landed on its feetÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ Careful analysis of the photos reveals the secret. As the catÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ rotates the front of its body clockwise, the rear and tail twist ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ counterclockwise, so that the total spin remains zero, in perfect ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ accord with Newton's laws. Halfway down, the cat ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ pulls in its legs before reversing its twist and then extends ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ them again, with the desired end result. The explanation was ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ that while no body can acquire spin without torque, a flexible ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@ one can readily change its orientation, or phase.
