7.1 The spectra of galaxies

  • The spectrum of a galaxy is the composite spectrum of the objects of which it is composed.

  • The optical spectrum of a normal galaxy contains contributions from stars and HII regions. An elliptical galaxy has no HII regions and has an optical spectrum that looks somewhat like a stellar spectrum but with rather fainter absorption lines. A spiral galaxy has both stars and star-forming regions, and its optical spectrum is the composite of its st

Persepolis Recreated-Part 2 of 5
Persepolis once stood where present day Iran is located. This documentary is suitable for high school students. "Archaeological evidence shows that the earliest remains of Persepolis date from around 515 BC. André Godard, the French archaeologist who excavated Persepolis in the early 1930s, believed that Cyrus the Great chose the site of Persepolis, but that Darius the Great built the terrace and the great palaces" (Persepolis, Wikipedia, 2009).

The Design and Analysis of Computer Algorithms
A text book for a first course in design and analysis of algorithms. The emphasis is on ideas and ease of understanding rather then on implementation details or programming tricks. It starts with formulating several models that include random access register machine, random access stored program machine and variants of these, so one can establish analytical results and at the same time accurately reflect on the salient features of real machines

Developing a new endoscopy laboratory with digital tools.
Tampere School of Architecture had to leave its old down-town building and move to the TU Tampere university campus in Hervanta, 10 km away. In this process, the 20 years old endoscopic system "The Urban Simulator" was one of the victims. Old mechanical parts and especially the original home-built microcomputer system were too old to compete with modern computer-aided methods. A new endoscopical system is now under construction, using all of the 20-year experience, new technical components and c

The representation of type in grammatical design
Grammatical design is useful for the generation of a set of related designs. The concept of type aids designers in generating designs with a specified structure. However, existing studies in grammar are ambiguous in their definition of type in the language of designs generated by a grammar. Extending our previous study of defining style in grammar, this paper provides a formal definition of the concept of type in the language of designs generated by a grammar. This is done with the help of a des

Introduction to Islam--G-d as the Creator and Originator of the Universe
Speaker Naseem Mahdi gives a 9 minute introduction to Islam. One of the 100 Attributes of G-d, G-d as the Creator and Originator of the Universe. Rather than just a straight ahead intro to Islam, this is a description of one of the tenets of Islam. It is only slightly less than neutral, but not offensive in any way. Extremely informative and thought provoking.   Run time 09:58

Computer Visualisation as a Tool in Architectural Historical Research
The historical city has been represented over time using various ways of drawing, modelling and simulation. Using different kinds of visual information as a basis, computer visualisation techniques are used in this presentation to reconstruct the urban development in the twentieth century of the town of Heusden and other towns. The resulting visualisation provides us with a tool for a better understanding of the dynamics of urban transformation processes, typologies and morphological changes. Th

8 An unsolved problem!

A lot of the mathematics you have looked at so far in the course has been used to help people solve problems for centuries. However there is much more to mathematics than that! Exciting and new developments are being made all the time and there are many problems that mathematicians have not managed to work out. This section takes a brief look at one of these problems.

It was unsolved at the time of writing!

In 1742, a Prussian mathematician, Christian Goldbach, made the following
