Send us your questions

Some of our visitors have sent emails with interesting questions, we decided to start having a space to answer them. In this space the blog "Restless Minds" will answer all questions you send us
Send us your question for the email: Restless Minds.

Science progress affects our daily life and "to know" means you are going to chose right, because it allows you to form your own opinion on scientific everyday issues. On the other hand, having an elegant and harmonious vision of the world where we live in leads to a feeling of intellectual satisfaction.
We believe this kind of scientific day to day knowledge should be encouraged from an early age, and that's why this project was born: science, culture, knowledge, crafts for your restless mind.

Start the year with brain gym

Let's start 2012 with a brain teaser:
Don't use paper or a pencil, just your brain, be fast as keep adding the numbers, keep the calculator away from you


  • Take the 1000 number,
  • Add 40,
  • Add another 1000,
  • Add 30,
  • Add again 1000,
  • Add 20,
  • Add 1000,
  • And add 10.


Whats the total?


5000?


You should try again, the number is 4100!!!




What hapened?
Your brain is confused by the sequence of decimal numbers, and automatically jumps to the  higher decimal (que acontece e que a sequência decimal confunde o nosso cérebro, que salta naturalmente para a mais alta decimal (hundreds rather than tens).

Et voilá!
Another brain mistery!


Enjoy!
