It's easy to look at the world and feel hopeless. War, poverty, disease, depression, cruelty and pan-flute music are everywhere. But I don't think we need to give up on the future just yet. I think the human race is remarkable. We invented Science and that gives me hope.
The word Science comes from the Latin Scientia which means "knowledge", and it is through knowledge that we'll survive. The more we understand this beautiful Universe in which we float, the more learn who we are, why we're here and what we're capable of. I really believe (and I will not apologise for optimism) that Science is our greatest invention and we're going to use it to save the species.
Everyone can be a Scientist because everyone can learn about the world. The more people learn about the world, the better the world becomes.
