I want to argue in the following way. It's that, well, all we are today in fact is governed by physical law. What are the physical law? How many physics students are here? None. Oh, they are doing experiment. Okay. One. One. Okay. So they're doing experiment. So, what are the physical law? Let me point out. There are two very important component. We learned about thermodynamics, right? So what is it? It's, well, we have a tendency. Whenever you have a system where it has a higher energy and you have a system which is of the lower energy, so what happens? It's that the one with higher energy tends to go to the lowest energy. So that's what I call. People tends to be at the lowest energy and that's the most stable one. So, you can understand how it occur. In the morning, you don't want to wake up. You want to be at the lowest energy because you want to stay that way. That's the most comfortable place. So that's one thing. Second thing is about entropy. The entropy is about how orderly we are. So what happen is that, again we follow that rule. Simply go home and look at your bedroom. You want it to be as disorganized as possible. You don't want to tidy it up. And so therefore, that's what happened. So therefore, whenever you have a chance that you get accused for being very disordered, disoriented, and you are lack of energy, you simply say that you follow the physical law. That's what you are. But actually what happens in between, from all these physical element and chemical elements, we make life. What life is really about is, we try to inject into it some energy and we put things into order. That's why you and I, we all look the same. We have like, two arms, two legs. We have a head. We have all this function, we walk around because somebody injected energy into us. Whether it's God, whether it's mother nature. Okay, you make the decision, but this is what life is really about. So actually, what we see is that, in fact, the selection of all this element is also very precise. If you look at all the elements on Earth, there are large number of them. The distribution you may find out and in fact the most abundant one are oxygen and the silicon. But if you look at life, living individual, in fact the majority of them actually is oxygen, nitrogen, carbon, and hydrogen. You combine them all together. Now we call them the carbohydrates, amino acids, and all the lipids. That are made of carbon, hydrogen, oxygen and nitrogen. So that's why it is. So essentially what the energy provides us is that, this specific injection of energy come in, selected a subset of these element, grouped them together, made them in an orderly way that create some basic life form. With that in mind, then we need to ask ourself, "Hey, actually what makes us very unique about it?" So then I would say, this is the living world. This is us, a human being. And what we ask is that, all along we ask about, hey, what happened? We are very curious. We ask about what happened. We ask about, hey, how things happen? And when you get a little bit older and wiser, you'll start asking why things happen. And that's the question, in fact most of us, we don't have an answer. And sometimes we simply boil it down and say that's probably due to some other higher beings that controls it. So that's what we are. We are very curious, and we are curious to a point that sometimes we do crazy things. For example, this one is a Maya's bust, which is about 1,000 years ago. So the one that people do is that they create such a bust. What does that mean? We want to know actually who we are. So what we do is that we cut that body open, look at what it is. If you look at you and me, you probably would not be able to draw something like this. How would they be able to draw it? Probably they have cut up something so that they can visualize it. And so they document it as something like that. And in time after another 1,000 year, this, another crazy guy called Da Vinci, he did the same thing, right? So he take a lot of corpse, cut it open, look at how the skull is like and he draw in very detailed figure. Plot it all down. And then he also did that with the heart, cut it open, look at the artery. He even look at all the nerve and all these things. It's a little bit crazy if you look at it today, but, I think for scientists, scientists need to be crazy. And he did that so that he would be able to understand actually who we are, and what, how we are make up, and what is inside.
