Secretary of Defense under George W. But when it comes to the universe, British mathematician Marcus du Sautoy readily admits that there are many things we may never know, from the nature of time to how human consciousness works. How far can science get us and what is beyond that edge which science will not be able to know? Take the universe edge, which is a question about whether we could ever know if the universe is infinite.

Could we ever know that? One of the most shocking discoveries in my journey to this edge is that because our universe is accelerating in its expansion, things are being pushed over this edge faster than the edge is growing! Tell us about the Las Vegas dice you keep on your desk—and what it can tell us about probability. I was drawn to mathematics as a subject because I hankered after certainty and the power of mathematics to prove things with percent certainty. Post-Newton, we seem to have the tools to maybe look into the future and know with certainly what might happen. But why have those tools failed to help us to predict, for example, how dice will fall?

I went off to Vegas to try and make some money, using my mathematical tools, and realized how sometimes they can be very impotent.

Here's Where We Might Reach the Limits of Science

Chaos theory tells us that our intuition of a good approximation of the present should help us have a good approximation of the future. But this is actually false. Small errors can explode into large differences in predictions. As chief time scientist at the U.

Naval Observatory, Demetrios Matsakis has spent his career monitoring time, including making sure that the Navy's master clock is always right. Over the years, he's developed some interesting theories about time.

Science has usually been antithetical to the idea of God. Talk about your conversations with the British quantum physicist John Polkinghorne, and how your journey to understand the unknown changed your views about God. I kind of rejected conventional religion because once you learn the scientific story, it seems to offer better explanations about the way the universe works.

But when I took over from Richard Dawkins as the Simonyi Professor for the Public Understanding of Science , the question of my own beliefs kept coming up. People were intrigued to know, am I going to be a militant atheist like Richard? Certainly, I signed up to rejecting the idea of a supernatural intelligence, which is the conventional view of what God is.

But there was something interesting in the idea of knowledge that will always transcend the ability of humans to comprehend. Quite a few scientists I talked to on this journey turned out to have some sort of religious angle, like John Polkinghorne, who trained as a quantum physicist but halfway through his career got ordained as a priest.

Polkinghorne is a theist, who believes his God acts in the world. One of the unknowns of the world comes from quantum physics, which says that the future is not determined by the present. I wondered whether Polkinghorne might see that as an expression of the action of his God in the world. Weirdly, he went for chaos theory as the way his God acts in the world. What was the idea behind that—and will we ever be able to fully understand time? We know that if we send something off to a large gravitational field, time will slow down, which is equivalent to accelerating something.

So, if I sent one of my twin daughters into outer space and accelerated her back again, her time will have gone slower than her twin on Earth, with the extraordinary result that she might come back and discover that her twin sister is 80 years older than her. This is one of the important components of the film Interstellar.

Limits to human enhancement: nature, disease, therapy or betterment?

They realize that going into a gravitational field, like a black hole, has a cost in terms of time. They want to return to see their children and they know that any time spent near a large gravitational field will slow their time down. Einstein already began to question whether we really know what time is.

We thought time was absolute. Newton certainly thought time was ticking at the same rate everywhere. Human consciousness is another of your great unknowns. Tell us why understanding consciousness remains such an intractable problem—and how you conducted experiments on your own brain. What flows is world. In this sense time doesn't exist. It has, just like space, its Center and it is the embodied mind.

The mind is always in the present; "behind" it there always stands the past; "in front" of it-the future is directed. The world floates against the embodied mind in direction from the future through the present to the past: first we expect the events, then we go through them and finally memorize and forget them. Does the perceived world have a transcendetal form independent from the human's artifacts; a form which is common to all the people? What kind of form is it?

go here Man is an embodied mind and a community of minds. As a specified body, the human being finds a specifically ordered world. This world is such that the Self experience re-emergence of the world, re-synthesis of the body against disintegration and expansion of its own form. There is an order of the life world which is common to every person-"The First Order.

The first order can be described as the one having time, space corporeality and eventfulness. It is organized by logical definiteness. The first order is not sufficient for survival of the man but it is crucial for the construction of the following strata and order which characterize every culture. How is the comprehensiveness of the perceived world organized the sense of causality and the teleology as mental forms?

Thought orders things and events in such way that it is possible to act efficiently at the highest degree on the conditions of the energy that flows out. That means that these actions have a form, trajectory, teleology. The action requires a synthesis of chains of events.

Man finds such chains ready-at-hand causal chains. The causal chains are put and combined with human physical actions. The designation is to reach the goal-survival and expansion. Science is an artifact. What is the artifact as a form and a plan of ordering? The artifact as a human creation is not alive. It hasn't his own world and couldn't reproduce itself.

It is a sign, behavior, psychical and mental form. The artifacts-tools, signs, models of action, manufactures and technologies-have the grounds for their existence outside of themselves-in the Self which is incarnated and whose aim is expansion. The artifacts mediate ways and structures that make possible the orientation and the expansion of the communities.

What is the cultural root of the Western form of ordering of the life world out of which empirical science was generated? Empirical science has no transcendental roots in the structure of the mind Kant, Husserl. It is a cultural fact.

The Limits of Science - A Critique of Scientism

We cannot find it in the ancient East. It has gone there from the West. Logos is is an order by means of words and numbers, theories and conceptions. According to the Western logos the world is transparent for words and thought. What are the projections of the logos in the common sense of Western man, in the objective knowledge and in empirical science doxa, epistema, scientia? Empirical science- scientia -originates in the most recent antiquity.
