- These slides contain some images from Google Earth that you can use to motivate discussions and set problems in the classroom.
- The emphasis is on topics in discrete maths.
- Images are for classroom-based educational use only.

- Images of the Wightlink and Brittany Ferries terminals in Portsmouth.

- These images are for the classic “Bridges of Königsberg” problem.
- The area is now known as Kaliningrad.
- The current bridges are different from the original ones but the topology of the problem has not changed.

- The smaller island is historically interesting.
- It is home to Königsberg Cathedral and is the burial place of Immanuel Kant. (Wikipedia)
- Compare the parks and cathedral with the motorway passing through!

- Much can be discussed about the city of Barcelona.
- The more modern parts of the city can be clearly distinguished by the “blocks” style layout.
- In fact the blocks have ‘shaved’ corners (so they are actually octagonal) to ease traffic flow. Most are 1 way streets.

In Catalan, the streets’ names are “Avinguda del Paral·lel” and “Avinguda Meridiana”

- The Eixample* is home to my “how many ways can I get to university?” problem.
- My house and the university are highlighted on the next slide.
- Streets are then highlighted.
- An extension includes narrower, additional ways.
*Pronounced along the lines of “I-sharmpler”

Maps of Barcelona are printed with this orientation. North is no longer “up” the page!
