How many times do you think you need to fold a piece of paper to reach the Moon? The answer seems like a lie, but it isn't

SOL1 September 2026 at 11:06

The question of how many times a piece of paper needs to be folded to reach the Moon has an answer that surprises with its simplicity. Human intuition suggests hundreds or thousands of folds would be needed, but mathematics shows the actual number is significantly lower.

The phenomenon behind this mathematical illusion is related to the exponential growth of the paper's thickness with each fold. When a sheet is folded, its thickness doubles, creating a progression that starts slow but quickly becomes impressive.

With just about 42 folds, a sheet of paper with an initial thickness of 0.1 millimeters would reach a distance greater than the 400,000 kilometers that separate Earth from the Moon. This counter-intuitive result demonstrates how the human brain struggles to comprehend exponential growth.

The article highlights that this is a lesson about the importance of not relying solely on intuition when it comes to understanding mathematical phenomena, as numbers can reveal truths that contradict what seems logical at first glance.

Air conditioning halves heat-related deaths, but does not protect against extremes

A study from Yale University in the United States revealed that the use of air conditioning reduces by half the number of annual heat-related deaths in the country, saving more than 5,000 lives per year. However, the study also warns that air conditioning is not sufficient to protect against extreme heat, highlighting an important limitation of the technology.

Study detects marine litter decades old from the USA and Canada in the Azores

A scientific study collected and analyzed 1577 items of marine litter on the coastal zones of the islands of Faial and Pico, in the Azores, identifying waste originating from the United States and Canada, some several decades old. The research allowed mapping the profile of marine pollution in the region and demonstrating how sea currents transport plastic debris and other materials across the Atlantic, affecting even remote archipelagos.
