An invention acts rather like a trigger, because, once it's there, it changes the way things are, and that change stimulates the production of anothe… - James Burke

Never before have so many people understood so little about so much.

Einstein's theory was that everything about the laws of the universe and nature was relative. What you observe about something depends greatly upon your frame of reference at the time. That's why I can stand here in this Concorde [jetliner]cabin and drop my pen in comfort. In here I'm not traveling 1,400mph, am I? Everything works like that. Conditioned by its frame of reference. All the electronics in all the instruments in this cockpit obey the exact same laws they would if the plane were standing still. Because in this frame, like me they are not traveling at Mach two. And all the laws of nature behave the same way. This beam of light is going out in all directions at 186,000 miles per second. Being on the concord makes no difference to it's speed going forward, backwards sideways.

So, in the end, have we learned anything from this look at why the world turned out the way it is, that's of any use to us in our future? Something, I think. That the key to why things change is the key to everything. How easy is it for knowledge to spread? And that, in the past, the people who made change happen, were the people who had that knowledge, whether they were craftsmen, or kings. Today, the people who make things change, the people who have that knowledge, are the scientists and the technologists, who are the true driving force of humanity. And before you say what about the Beethovens and the Michelangelos? Let me suggest something with which you may disagree violently: that at best, the products of human emotion, art, philosophy, politics, music, literature, are interpretations of the world, that tell you more about the guy who's talking, than about the world he's talking about. Second hand views of the world, made third hand by your interpretation of them. Things like that [art book] as opposed to this [transparency of some filaments]. Know what it is? It's a bunch of amino acids, the stuff that goes to build up a worm, or a geranium, or you. This stuff [art book] is easier to take, isn't it? Understandable. Got people in it. This, [transparency'] scientific knowledge is hard to take, because it removes the reassuring crutches of opinion, ideology, and leaves only what is demonstrably true about the world. And the reason why so many people may be thinking about throwing away those crutches is because thanks to science and technology they have begun to know that they don't know so much. And that, if they are to have more say in what happens to their lives, more freedom to develop their abilities to the full, they have to be helped towards that knowledge, that they know exists, and that they don't possess. And by helped towards that knowledge I don't mean give everybody a computer and say: help yourself. Where would you even start? No, I mean trying to find ways to translate the knowledge. To teach us to ask the right questions. See, we're on the edge of a revolution in communications technology that is going to make that more possible than ever before. Or, if that’s not done, to cause an explosion of knowledge that will leave those of us who don't have access to it, as powerless as if we were deaf, dumb and blind. And I don't think most people want that. So, what do we do about it? I don't know. But maybe a good start would be to recognize within yourself the ability to understand anything. Because that ability is there, as long as it is explained clearly enough. And then go and ask for explanations. And if you're thinking, right now, what do I ask for? Ask yourself, if there is anything in your life that you want changed. That's where to start.
