Here is a very informative essay about how basic mathematics, physics, and biology allow us to deduce what is and is not possible for giant monsters in movies.
Fibonacci numbers are 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, … where the next number is the sum of the previous two numbers (2 = 1+1, 3= 2+1, 5 = 2+3, etc.)
We found Fibonacci numbers in many things in nature (due to growth and efficient packing of parts.) This is a page that lists many interesting things about the numbers and activities that adults and kids can do for fun.
