A catalyst is an agent that provokes or speeds significant change or action, at a faster rate or under different conditions; an agent that causes activity, inspiration and enthusiasm between people. Exactly like some chemical reactions wouldn't be feasible, or fast enough, without a catalyst, some social changes necessitate a successful individual, or a group, to engage and make their community better; this is what makes them catalysts for change. Egyptians have been catalysts for change on many levels and in a variety of disciplines, and now the perfect time to share this with the world.
