"Fundamentals of Physics" by Halliday, Resnick, and Walker is in its 10th edition (published 2013). This edition describes the basic physics of the same topics as HRK. However, it goes into less detail, omits some of the interesting calculations, and has fewer challenging problems. Although this is a good book, it is not written to train students to the same level of problem-solving ability as HRK. So HRK is recommended for those interested in improving their problem-solving ability to the level of the USAPhO or similar olympiad physics competitions.
My question is, why do textbooks often include the solutions to odd or even numbered problems but not both? In my case, I don't think space is the answer because the answers section only takes up 7 pages.
If an instructor just wants students to work on problems where the students can easily refer to sample solutions at the back of the book, the instructor can just assign "problems 1-7, odds only". If they want to assign only no-solution problems, they can assign "evens only". If they want to give a mixture to try to encourage students to mix up their solving strategies, they can assign both. To go farther, putting them at the back of the book was another way to try to make it take a little more effort to look for the solution, to encourage the students to try to solve it themselves rather than immediately looking at the solution.
The other answers cover what I think is the main reason, but I want to bring up something else: Putting solutions into a textbook is a lot of work; the editors have to find the solutions, write them up, typeset them, and someone has to proofread them. On the other hand, the additional benefit of another solution becomes pretty small once half the problems have solutions, especially in those textbooks that feature a lot of rather repetitive problems.
Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
One problem is standing out above all others in social science: how should humanity govern itself? The problem is so important that all wars of humanity in the past, present, and future, are directly related to this problem. Despite the fact that this problem has attracted interests of some greatest thinkers for thousands of years: Confucius, Plato, Aristotle, Machiavelli, Locke, Washington, Jefferson, Madison, Kant, Marx, Einstein, Hayek, and many others, yet the problem remains unsolved. The latest thinking on this humanity governing problem by mainstream social scientists is represented by views of Friedrich Hayek. In his writings, Hayek repeatedly warned that we must shed the illusion that we can deliberately create the future of mankind. This paper disagrees with Hayek and proves for the first time that this problem is solvable scientifically applying recently-created physics laws of social science, if the problem is formulated in a correct way: what kind of governing political structure of humanity is most stable? Most-stable structure problems appear routinely in the theoretical and experimental condensed matter physics. We show that the humanity governing problem is equivalent to find an equilibrium political structure of a human society, which is a many-body physics problem 100% solvable using the maximum entropy approach widely-used in the condensed matter physics. This paper establishes the framework and methodology of quantum politics and replaces traditional political philosophy with quantum physics as the solid foundation of political science, and analyzes the equilibrium political structure of a human society. The main results are quite surprising: (1) Quantum physics does provide a firm scientific foundation for social science. For the first time, political science, economics, and other social science become branches of quantum physics just like optics and chemistry. (2) Quantum physics says that we can create free, fair, just, peaceful, and prosperous human societies. We prove that there is certainly no better alternative than the equilibrium political structure, which is defined by a set of 16 democratic principles. (3) The existing democratic governments in the world can be improved in significant ways. For example, there are many fundamental design flaws in the US constitution. American civil wars, slavery, epidemic gun violence, and run away government debts are some direct results of design flaws of the US constitution. (4) Quantum physics clearly says that there is a global political equilibrium state, which corresponds to the permanent world peace. This paper provides a theoretically-sound and practical solution to eliminate the nuclear, biological, chemical, robotic, and other forms of weapons of massive destruction. In the long run, humanity can grow up and will put an end to deaths, miseries, and economic destruction caused by wars, which have been plagued us since the dawn of humanity.
A Princeton scientist with an interdisciplinary bent has taken two well-known problems in mathematics and reformulated them as a physics question, offering new tools to solve challenges relevant to a host of subjects ranging from improving data compression to detecting gravitational waves.
Salvatore Torquato, a professor of chemistry, has shown that two abstract puzzles in geometry -- known as the "covering" and "quantizer" problems -- can be recast as "ground state" problems in physics. Ground state problems relate to the study of molecule systems at their lowest levels of energy and have numerous applications across scientific disciplines. Torquato's conclusions are reported in a paper that was published online Nov. 10 by Physical Review E.
The three years 2001 to 2003 were the golden years of solar neutrino research. In this period, scientists solved a mystery with which they had been struggling for four decades. The solution turned out to be important for both physics and for astronomy. In this article, I tell the story of those fabulous three years.1
The standard model of particle physics is a beautiful theory that has been tested and found to make correct predictions for thousands of laboratory experiments. The standard solar model, on the other hand, involves complicated physics in unfamiliar conditions and had not previously been tested to high precision. Moreover, the predictions of the standard solar model depend sensitively on details of the model, such as the central temperature. No wonder it took scientists a long time to blame the standard model of particle physics rather than the standard model of the Sun.
The Bachelor of Science in Computer Science degree program is a mathematically rigorous, scientifically oriented curriculum that prepares students to become proficient in all fundamental areas and techniques of computer science. Students learn how to develop efficient algorithms to solve problems in a variety of application areas and implement their solutions using appropriate programming languages and computer systems. This degree program will also prepare students to pursue research opportunities and postgraduate studies in Computer Science.
Environmental scientists and specialists analyze environmental problems and develop solutions to them. For example, many environmental scientists and specialists work to reclaim lands and waters that have been contaminated by pollution. Others assess the risks that new construction projects pose to the environment and make recommendations to governments and businesses on how to minimize the environmental impact of these projects. Environmental scientists and specialists may do research and provide advice on manufacturing practices, such as advising against the use of chemicals that are known to harm the environment.
Analytical skills. Environmental scientists and specialists base their conclusions on careful analysis of scientific data. They must consider all possible methods and solutions in their analyses.
Measuring students problem solving ability is a non-trivialtask. Many researchers of classroom physics problem-solving usestudent grades as such a measure. While others do a controlledgrading where they have several expert physicists grade identicalsolutions, compare their respective scores, then reach consensuson differences. Both methods fall short of measuringproblem-solving ability. Instead what they measure is thecorrectness of a solution. A student who chose to apply the wrongphysics concepts, yet applied them correctly, typically receiveda low grade. Conversely, a student who managed to reach a correctsolution by manipulating all of the given information in ahaphazard manner would probably receive a high grade, yet failedto display a desirable problem-solving ability. This is not meantto imply that grades are without merit, only that grades measuresomething different than problem-solving ability. For this study,a more sophisticated technique needed to be applied.
To develop a technique to measure problem-solving ability, thefirst step is to decide what is meant by "problem-solvingability." For physicists, the only meaningful definition ofproblem-solving ability would have their students solve problemslike physicists. Fortunately, the expert-novice problem solvingliterature has already illustrated how expert physicists solveproblems. From this literature, four relevant behaviors areevident in expert solutions: (1) expert perform an initialqualitative analysis of a problem (Larkin, 1979); (2) experts usetheir initial analysis to create a domain specific representation(Larkin & Reif, 1979); (3) experts work from generalprinciples to the desired goal (Larkin, 1980); and (4) goodproblem-solvers plan their solution before starting it (Finegold& Mass, 1985). From these four behaviors, a problem-solvingability coding rubric was developed. 59ce067264
