Angles in Nature
leaf branching angles
Eratosthenes: The Size of the
Earth
Eratosthenes realized: Distance/Circumference = Angle / 360
(from Cairo) Circumference = 700 km × 360 / Angle = …
Circumference = 700 km × 360 / 6.5° = 38769.2308 km
Circumference = 700 km × 360 / 6.5° = 38769.2308 km ≈ 40,000 km
Circumference = 700 km × 360 / 6.5°
Eratosthenes: The Size of the
Earth (cont)
Eratosthenes realized: Distance/Circumference
= Angle / 360

Try to line up teeth (near and far) so they make a straight line —unlike this image
Facial Recognition
What other angles do you think might be diagnostic?
