Othello and apartheid
Can a play written in the seventeenth century protest against contemporary issues? Is it possible to use a Shakespearian tragedy draw attention to political injustice? Apartheid was a system of enforced legal racial segregation in South Africa that was imposed on the country's majority non white inhabitants by the minority white population. In 1988 actress and director Janet Suzman took the decision to defy the racist apartheid regime by staging Othello in Johannesburg with a mixed cast of both

2 Your own mathematics

It is crucial to remember that you are a learner of mathematics as well as a teacher. In this course you will be asked to undertake some mathematical tasks. The aim of these tasks is not to improve your mathematics, but to give you experience of doing mathematics for yourself—experience that you can reflect upon subsequently. The reflection is used to develop your awareness of the ways that learners deal with mathematical tasks, and how learners' mathematical thinking is influenced by the w

6 Conclusion

The major thematic contrasts of European development in terms of unity and diversity, and conflict and consensus, thus persist at the beginning of the twenty-first century, although aspects of unity and consensus had tended to prevail following the relaunching of the European project after 1945. Although this represented something of a break with tradition for modern Europe, it was by no means clear that this represented a full-scale transformation or pointed to the emergence of a Europe that

7.6 Arithmetic with binary fractions

My final point in the preceding section brings home the fact that integer arithmetic is not really suitable when divisions are to be performed. It is also not suitable where some or all of the values involved in the arithmetic are not – or are not necessarily – integers, and this is often the case. In such cases, arithmetic has to be performed on non-integers.

The most common representation for non-integers is the floating-point representation that I mentioned briefly in Box 3. You

3.1.1 Stellar masses and stellar evolution

  • Measured stellar masses range from about 0.08M to about 50M, with stars of lower mass being more common.

  • Stars lose a rather small fraction of their masses during much of their lifetimes, but much larger fractions when they shed planetary nebulae, or when they undergo supernova explosions.

  • When stellar masses are placed on an H-R diagram, and coupled with observations of mass loss,

Cosine Ratios
This video explains how cosine ratios, along with sine and tangent ratios, are ratios of two different sides of a right triangle. Cosine ratios are specifically the ratio of the side adjacent to the represented base angle over the hypotenuse. In order to find the measure of the angle, we must understand inverse trigonometric functions. (2:03)
