According to Wikipedia the word ''inertia'' refer to a resistance of any physical object to any change in its state of motion (including a change in direction). In other words, it is the tendency of objects to keep moving in a straight line at constant linear velocity. Inertia is also what make complicate changes inside citizens, countries, cities. TEDxFirenze Team belives that there are many ideas between young or older creatives that can fight this inertia. In the next TEDxFirenze event we will try to collect those creatives, inviting them to partecipate to event to explain us what's their idea for a change, against inertia.
