根据第三段第一句 “As a matter of fact, the main reason why many people do not excel in mathematics is the widespread worry and unease.(事实上,许多人数学不擅长的主要原因是普遍存在的担忧和 不安。 )”可知,人们不擅长数学的主要因素是与这个学科相关的担忧和焦虑。故选B。 【13题详解】 词句猜测...
Singularity (MathematicsBoundary Value ProblemsFluid DynamicsNonconservative ForcesPerturbationPipes (TubesThe equations of gas dynamics in a tube with varying cross section are an example of a nonhomogeneous system of conservation laws. In this work we study the Riemann problem for this system by ...
While students of these two groups of teachers started off with no difference in their math performance, the students taught by teachers who completed the program increased their mathematics performance by 0.18 points on average. This is a statistically significant gain that is equal to the average...
Conservation and sustainable development Of course, working in other countries often requires a work visa or permit – this can be difficult, as it may involve finding an employer to sponsor you, paying a visa application fee, and the employer demonstrating that they cannot hire someone for the...
ICM teams could take what they know about data and modeling to help conservation groups design better policies for protecting endangered species. By tracking animal populations and identifying risks, they could give wildlife a fighting chance. Their work would also help keep ecosystems healthy for the...
Discrete mathematics is the study of mathematics confined to the set of integers. While the applications of fields of continuous mathematics such as calculus and algebra are obvious to many, the applications of discrete mathematics may at first be obscur
Modelling is at the heart of applied mathematics. Here, we look at some of the basic ideas and methods that underlie many mathematical models such as conservation laws and approximation. Such approximations should be rational and can lead to simpler systems of equations that can be solved more ...
