The Global Goals

This is a new type of blog post I have never done, but I am excited about the idea. I believe some of you already know about the Global Goals project. The idea is that the World Leaders decided to commit to 17 Global Goals to achieve 3 extraordinary things by 2030. The Global Goals for sustainable development could get these things done. In all countries. For all people. With this in mind they started a campaign to make the 17 goals known to everyone and I thought about joining it.

The idea is to share your opinion about the campaign and also talk about one of the goals you feel it is the most important. I have chosen number 4 (Quality Education). Because I don’t want to have a post without a little mathematics, let us see some interesting number facts about 4:

  • 4 is the smallest squared prime (p2) and the only even number in this form;
  • it is the only composite number n for which (n - 1)!\ \equiv\ 0 \ ({\rm mod}\ n) is false;
  • is the smallest composite number that is equal to the sum of its prime factors;
  • a circle divided by 4 makes right angles. Because of it, four (4) is the base number of plane (mathematics). Four cardinal directions, four seasons, duodecimal system, and vigesimal system are based on four.

Back to the 4th Global Goal: Quality Education. Did you know that:

  • 42% of African school children will drop out of school before finishing their education?
  • currently only 49% of children will attend secondary school?
  • an estimated 250 million children are not learning basic reading and maths skills?
  • one in four young people in developing countries are unable to read a sentence?

For me this goal is one of the most important of all those 17 the project talks about. Quality education will give more to everyone in the future and it could help us understand more about the world around. Quality education influences the other Global Goals, such as No.1 (No Poverty), No. 8 (Decent Work and Economic Growth), No. 12 ( Responsible Consumption and Production), No. 13 (Climate Action) and much more.

Which is your favorite Global Goal? Participate in the campaign, show your support in any way possible. Visit the website to find out more about it and how you can support it. One of the many things you can do is a selfie: choose your favorite goal, take a selfie including the number of your goal and share it with everyone.


You could share them with me anywhere on Facebook, Tumblr, Google+, Twitter, Instagram  or Lettrs. Thank you for your help and support. Don’t forget that maths is everywhere! Enjoy!
