Learning is not an option anymore: it's a real need in a world that changes at lightning speed. As new technology comes in, new skills are required for playing hard in the labor market as well as being able to seize the world around us.
Online education is booming. In developed countries, it's seen as a way towards bulletproof careers. In most developing countries, it's a lifeboat for those that cannot access traditional educational institutions. Non-profit initiatives like Khan Academy have lowered barriers to access educational resources across a whole range of important topics (Math, Science, Economics...) in the easiest-to-digest format: video master classes.
Khan Academy has recently launched its official Android app, so you too can join this revolutionary movement right from your mobile phone. Start learning on your downtime and keep growing both personally and professionally without breaking a sweat.
