How many objects are there in the World?

04 April 2015 1 3K Report

Hi, I need to know that how many objects people can recognise or how many objects are there in world? if this question is trivial, I'm sorry, but I did not find this anywhere. I tried to achieve this information by looking at object numbers in Enlish, but I could not go so far.

With some limitation and simplification, I would say the number of objects in the world is N, which is less than 550,000 ~ 700,000. This range is the number of nouns in English. Here, the red apple and yellow apple's difference is ignored. To make it more accurate, may introduce the combination, the approximate maximum will be CN1 + CN2 + CN3 + N * M, M is the number of adjectives.
