SUMMARY

Primo Levi's calculation regarding the distribution of human mass over the Earth's surface concludes that if the total human mass of 250 million metric tons is spread evenly, it results in a "human surface" thickness of 16,000ths of a millimeter. This calculation is based on the assumption of a human body density of 1,000 kg/m³ and the total surface area of the Earth being 510 million km². The reference for this calculation is found in Levi's book "Il sistema periodico" (The Periodic Table), specifically on page 168.

PREREQUISITES
  • Understanding of basic density calculations
  • Familiarity with metric units (metric tons, kilograms, millimeters)
  • Knowledge of Earth's surface area measurements
  • Basic comprehension of Primo Levi's literary works
NEXT STEPS
  • Research the concept of density and its applications in real-world scenarios
  • Explore the mathematical principles behind surface area calculations
  • Read "Il sistema periodico" by Primo Levi for context and deeper understanding
  • Investigate the implications of human mass distribution in ecological studies
USEFUL FOR

This discussion is beneficial for students, educators, and literary enthusiasts interested in the intersection of science and literature, particularly those studying Primo Levi's works and their scientific references.

Primo Levi: "Human Surface"

Homework Statement


http://answers.yahoo.com/question/index?qid=20101205082200AAZCums

What calculation did Primo Levi use to get the following conclusion:
According to Primo Levi's book, if the human mass of 250 million metric ton would be spread over the surface of earth, the thickness of the "human surface" is 16000st of a millimeter.
The density of a human body in this case would be 1000kg/m3. Surface Earth = 510 million km2

Homework Equations


None


The Attempt at a Solution


I wouldn't have the slightest idea to solve this.

Thanks in advance!

Did you make this up? What book is this? :confused:
 


I'm totally confused myself too. None of my friends could solve it either. I'm sorry if it isn't fully understandable because I'm Dutch :).

Book: "Il sistema periodico ("The Periodic Table") p.168 (Primo Levi) I think...
