2.4.1 Remarks

  1. This theorem applies to all surfaces and not just to surfaces in space.

  2. This theorem tells us that the boundary number is a topological invariant for surfaces, i.e. a property that is invariant under homeomorphisms.

  3. It follows from the theorem that two surfaces with different boundary numbers cannot be homeomorphic. It does not follow that two surfaces with the same boundary number are homeomorphic –

Extending water resources
Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there are areas where water supplies are limited, shown by recent droughts. Globally, there are many areas that do not have enough water to support the current population adequately. Decisions will have to be made on the best way to use water in a worl

How to Build a Time Machine
We think of time travel as fiction, but there is nothing in the laws of physics that prevents us building a time machine. What's more, relativity provides practical opportunities to travel through time. Listen back to Brian Clegg, author of 'Dice World, Gravity, A Brief History of Infinity, Inflight Science and Build Your Own Time Machine', talking about the potential solutions to time travel from our recent public lecture.Author(s): No creator set

Notched zinc, broken by impact at room temperature
This is a notched zinc specimen broken by impact at room temperature. It has failed by a cleavage mechanism. One can observe the cleavage planes clearly separated by regions of local shear, where the fracture path crosses to adjacent planes. The cleavage planes are atomically flat and are not associated with much plastic deformation. At low temperature metals having b.c.c. and h.c.p structures have insufficient independent slip systems operating and are brittle, fracturing by cleavage.

1.2.5 Summary of Sections 1.1 and 1.2

  1. The majority of organisms are exposed to environmental fluctuations, including seasonal change in climate. In this course, we focus on the effects of winter.

  2. Organisms have evolved a range of strategies to cope with winter. Thus this common environmental variable has led to a diversity of responses.

  3. The strategies for coping with winter can be considered with respect to different levels and types of explanation.

Global Climate Change: Perspectives from the Past
People are constantly asking how today's climate compares with detailed climate records from tens of thousands of years ago to tens of millions of years ago. To the best of our knowledge, we have to search back 55 million years to find a time interval where the rate temperature changes were anywhere near the rate of change that is occurring now. This time interval is called the Paleocene- Eocene Thermal Maximum (PETM). In this lecture, Dr Opdyke compared data from the Eocene to data collected fr

Academic research on student engagement - lost formulae to inspiring students
This paper shows academic tutors take on a multitude of roles in their current positions at university and while teaching is expected, from most, it is often assumed that the tutor will apply appropriate pedagogical tools to convey knowledge to the students. This view is now being challenged as many students are being actively encouraged to voice their views of the teaching and learning experience this paper shows
