Title: Konigsberg Bridge Puzzle
1Konigsberg Bridge Puzzle
What exactly was the point in that?
2Puzzle
- Can you cross all the bridges without crossing
one twice?
Im sorry, but that was childish and immature.
3Answer
NO!
4Why not?
- Leonhard Euler solved this problem by making a
new mathematics known as Graph Theory. He said
that you cant solve the problem because there
are an odd number of bridges on each island and
that it would need an even amount on each island
to be able to cross every bridge without crossing
one twice.
5Is your information factual?
Can you see that the example makes this is a
false statement?
- you cant solve the problem because there are
an odd number of bridges on each island and that
it would need an even amount on each island to be
able to cross every bridge without crossing one
twice.
Is that really what Euler concluded?
- Consider this example
- I have 4 islands.
- Each segment represents a bridge.
- All islands can be visited, all bridges can
be crossed without crossing any bridge twice.
- Two of the islands have two connecting
bridges, and two of the islands have three
connecting bridges.
6Background
- The townspeople of Konigsberg would try to cross
all the bridges without going over a bridge twice
but nobody could figure it out. This puzzle had
been around for more then 300 years before any
one figured it out.
This sort of stuff is annoyingand very
immature.Put your efforts into the research!
Again,Put your efforts into the research. I have
no confidence in this statement.
7Stick to the Guidelines, This presentation is
lacking in at least the following ways
- Too much unnecessary, silly animation.
- I cant imagine that anyone proof-read this.
- No examples of diagrams that can be drawn without
lifting the pencil (I demonstrated this in
class). - No examples of how Graph Theory applies to our
technology-driven society. - Overall, I am offended that I have students that
do not take me any more serious than to present
something like this!
