The reason you want a high score is simple. The higher your score, the better you look to the admissions officers at the college of your choice. The SAT II Physics Test is designed to measure the knowledge and achievement of high school students who have completed a college preparatory physics class. This book will help you review for the SAT II Physics Test. If you have not taken a Physics class yet, it may be advisable to wait until after you complete one before you progress further. This book is arranged in several sections, beginning with a diag- nostic test. The purpose of this test is to identify your strengths and weaknesses. It will also help to familiarize you with the testing method used by the College Board. Do not skip the diagnostic test! Find a quiet, comfortable spot, turn off the TV, computer, and music, and try to take the entire diagnostic test within the time allotted. If you run out of time, mark on your answer sheet where you ran out of time. Then keep going until you complete the test. After finishing the test, you deserve a break, so take one. But be sure to come back after no more than 15 minutes and check your answers. Then go back, reread the questions you missed, and try to figure out what went wrong. Did you jump to a conclusion, misread the question, stop at the first correct answer (sometimes there are multiple correct answers to one question), or just not know the mate- rial? None of these reasons is cause for serious concern right now, because every reason mentioned can be overcome. In fact, as you work through this book, each of these will be addressed. Once the diagnostic test is done it’s time to settle down to your preparation for the real SAT II Physics Test. Move on to the Physics review and study each section as if you had to learn the material all over again. Those sections you know well will go by smoothly and help you to build confidence, while your review of unfamiliar terms and concepts will allow you to learn it quickly and effectively. www.theallpapers.com Peterson’s: www.petersons.com RED 1 ALERT RED ALERT When you have finished your review, take the practice tests. Once again, you should try to set up a test-like situation. Make sure all the electronic toys are out of the way (besides, the College Board doesn’t allow them), time yourself, and do your best. After you check each test, read the explanations for those questions you missed, and for addi- tional reinforcement, reread the Review Section that covers the mate- rial in the question. ABOUT THE PHYSICS TEST The SAT II Physics Test is a 75-question multiple-choice test. The test covers the following topics: • Mechanics • Heat/Kinetic Theory/Thermodynamics • Waves • Electricity and Magnetism • Modern Physics • Miscellaneous Topics (may include measurement, math, and history) Nearly 40 percent of the SAT II Physics Test will test your knowl- edge of Mechanics. Electricity and Magnetism also make up a signifi- cant proportion of the material, accounting for about 25 percent of the questions. Approximately 20 percent of the questions deal with

    WHY DARWIN DELAYED, OR INTERESTING PROBLEMS AND MODELS IN THE HISTORY OF SCIENCE ROBERT J. RICHARDS Though Darwin had forinulated his theory of evolution by natural selection by early fall of 1x37. he did not publish it until 1859 in the Origirr of Species. Darwin thus delayed publicly revealing his theory for some twenty years. Why did he wait so long'? Initially [hi\ may not seem an important or interesting question. but many historians have so regarded it. They have developed a variety of historiographically different ex- planations This essay considers these several explanations, though with a larger pur- pose in mind: to suggest what makes for interesting problems in history of science and what kinds of historiographic models will hest handle them In October of 1836, Charles Darwin returned from his five-year voyage on the Beagle. During his travel around the world, he appears not to have given serious thought to the possibility that species were mutable, that they slowly changed over time. But in the summer and spring of 1837, he began to reflect precisely on this possibility, as his journal indicates: "In July opened first notebook on 'Transformation of Species'-Had been greatly struck from about Month of previous March on character of S.

Darwin's views on evolution really only began to congeal some six months after his voyage. In the summer of 1837, he started a series of notebooks in which he worked on the theory that species were transformed over generations.

  • The Big Bang Picture: a Remarkable Success of Modern Science Alain Blanchard
    The Big Bang Picture: a Remarkable Success of Modern Science Alain Blanchard LATT, OMP, UPS, 14, Av. E.Belin, 31 400 Toulouse, France E-mail: [email protected] Abstract. During the XXth century a scientific picture of the universe and its history has emerged on the basis of the "Primeval Atom", the original proposition of Georges Lemaî tre. Indeed, I will show during this review that modern cosmology is a scientific theory, and as such does not pretend to provide the "Truth", but a framework in which predictions are possible and can be confronted to observations for possible falsification in Poper sense. The last forty years have offered a remarkable list of observational verifications of the predictions of the standard picture, on the basis of well established physics. During the last twenty five years a more revolutionizing picture has emerged: essential pieces of information for fundamental physics are obtainable from cosmology: this picture specifies the existence of non-baryonic matter, of dark energy and the physics relevant at energies well above what is accessible to terrestrial laboratories. Although definitive conclusions are obviously more uncertain, this approach is still a fully scientific path which successes have been remarkable and allow to consider cosmology as a new and rich branch of modern physics. Keywords: Cosmology PACS: 98.80.k 1. INTRODUCTION The status of cosmology as a science has been quite often debated. My personal point of view is that the question of Cosmology, i.e. obtaining the description of the geography and the history of the universe, is one of the oldest question of man kind, and therefore the scientific approach was much more difficult than say in thermodynamics.

  • A Christian Physicist Examines the Big Bang Theory
    A Christian Physicist Examines the Big Bang Theory by Steven Ball, Ph.D. September 2003 Dedication I dedicate this work to my physics professor, William Graziano, who first showed me that the universe is orderly and comprehensible, and stirred a passion in me to pursue the very limits of it. Cover picture of the Egg Nebula, taken by Hubble Space Telescope, courtesy NASA, copyright free 1 Introduction This booklet is a follow-up to the similar previous booklet, A Christian Physicist Examines the Age of the Earth. In that booklet I discussed reasons for the controversy over this issue and how these can be resolved. I also drew from a number of fields of science, ranging from the earth’s geology to cosmology, to show that the scientific evidence clearly favors an age of 4.6 billion years for the Earth and about 14 billion years for the universe. I know that the Big Bang Theory of cosmology is not so readily accepted in some Christian groups, precisely because it points to an older universe. But I appealed to reason and the apparent agreement with the scriptures [1] when considering the evidence. However, in an attempt to preserve a continuity of discussion, that booklet only briefly covers some of the scientific evidence supporting the Big Bang theory, and the following discussion of scriptural references did not emphasize any relevance to the Big Bang. There was much more to write on these, but it did not seem to fit well with the discussion on the age of the Earth. However, since I asked the reader to reason with me, it didn’t seem quite fair on my part to cut short the explanations.

  • Relationship to Mate Fecundity in the Southern Green Stinkbug, Nezaraviridula (Hemiptera: Pentatomidae)
    Heredity 64 (1990) 161—167 The Genetical Society of Great Britain Received 25 July 1989 Male copulatory success: heritability and relationship to mate fecundity in the southern green stinkbug, Nezaraviridula (Hemiptera: Pentatomidae) Denson Kelly MCL&n* Department of Biology, Landrum Box 8042, Nancy Brannen Marsh Georgia Southern College, Statesboro, Georgia 30460, U.S.A. Single male southerngreen stinkbugs, Nezaraviridula, sequestered in mating chambers with six females varied in the number of copulations achieved. Females copulating with relatively successful males were more fecund than females copulating with less successful males. This suggests that females mating successful males receive greater nutritional rewards per mating or that their risk of contagion is reduced. There was a significant correlation between the mating success of fathers and sons. Since egg quality (hatch rate) and egg size (diameter) did not covary with male copulatory success, this correlation indicates additive genetic variation for male mating. success in a natural population. Thus, for females there appears to be a positive relationship between offspring quality and mate effects on fecundity. Additive genetic variation for mating success may be maintained by countervailing mortality selection on males imposed by a parasitoid which is attracted by male pheromones.

  • Genetic Differences in Mating Success and Female Choice in Seaweed Flies (Coelopa Frigida)
    Heredity 62 (1989) 123—131 The Genetical Society of Great Britain Received 13 June 1988 Genetic differences in mating success and female choice in seaweed flies (Coelopa frigida) G. Engeihard, Department of Genetics, University of Nottingham, S. P. Foster and Nottingham NG7 2UH, U.K. T. H. Day An association is described in seaweed flies, Coelopa frigida, between the genotype at the alcohol dehydrogenase (Adh) locus and mating success in pairwise mating trials. Significantly higher mating success was observed in females that carried the Adh-C allele, but no association was observed between Adh genotype and male mating success. There was heterogeneity in the success of different combinations of males and females, but only when the female lacked the C allele. Analyses of video recordings indicated that C-bearing females spent longer mounted by males and that they less frequently rejected males. Evidence is presented for mate discrimination by females not carrying a C allele. The significance of there being genetic differences in both mating success and in female discrimination are discussed in the context of previous results on mating behaviour in natural populations.
