2. Research on bones
 Sometimes we speak of a certain proportion
between the body parts e.g.
 The ulna in the forearm of a person equals the length
of the persons feet.
 The distance between somebody’s neck and the tip
of his nose equals the length of his foot.
 The golden section can be found in the ratio between
the forearm and the hand.

3. Ulna and foot
 First we started to measure the ulna and wrote down
the results.
 Then the foot was measured and compared with the
measure of the ulna.

6. Ulna and foot
 The results from our research project shows that the
average difference between the length of the ulna
and the length the foot is 0.5 cm.
 Our conclusion is that the length of the ulna and the
foot is almost the same, so the saying is true.

7. Nose-neck and foot
 We started to measure the head, that is from the tip
of the nose to the neck, and wrote it down.
 Then we measured the foot and compared the
measures.

10.  The results from our research project shows that the
average difference between the mesuraments of the
head (tip of nose to neck) and the length of the foot
is 0.6 cm.
 The conclusion is that the distance between the
mesuraments are almost the same, so the saying
also seems to be true.

11. Golden section in the
forearm and hand
 Golden section is the ratio 1,618. It can be f.ex. Found in
nature, buildings and the human body.
 The ratio between the Fibonacci numbers
1,1,2,3,5,8,13,21… is the golden section.
 Here we were looking for the golden section by
comparing the measures between the forearm and the
hand.

14. Golden section in the
forearm and hand
 The results from our research project shows that the average
difference between the length of the forearm and the hand is 1.39.
 Measurements can be inaccurate and it is easy to make the wrong
measurement. If the average length of the ulna is 26.1 cm the
forehand needs to be 16.15 cm for the Golden section to be true
 The Golden section was not to be found in the ratio between
forearm and hand in our research so our conclution is that we
might have done something inaccurate in our measures. To say
that the saying is not true we would have to do this part of the
research again.
