The 50 most interesting scientific curiosities

Selection of the best scientific and technological curiosities

This post was written in 2008 Arcade, nine years later we have updated and completed it because many things have happened and now there are a few more than 50

Hundreds of strange facts beat science every day, here is a list of the 50 most curious. The election process was to have more than 100 people vote on the facts from a list [1] of 198 curiosities (Some of them were updated, to be consistent with current events). In the review of the article we have completed with current data and related facts and added a couple of points that we have found remarkable.

Many of you ask me by mail for interesting topics to present in class. So I take the opportunity to recommend this list, because almost any of these science curiosities can be expanded and exhibited in class.

Let's go.
