Quotes About Science

How will we feed an ever-growing population? Provide clean water, generate renewable energy, prevent and cure disease and slow down global climate change? I hope that science and technology will provide the answers to these questions, but it will take people, human beings with knowledge and understanding, to implement these solutions.

The fundamental postulate of the theory of relativity, as it was called, was that the laws of science should be the same for all freely moving observers, no matter what their speed.

To do research on the fundamental laws that govern the universe would require a commitment of time that most people don't have; the

Thus the possibility of time travel remains open.

Nature and Nature's laws lay hid in night: God said, Let Newton be! and all was light.

If the theory is confirmed by observation, it will be the successful conclusion of a search going back more than 3,000 years. We will have found the grand design.

according to the laws of nature concerning gravity and motion – laws that are among the oldest in science – space itself is a vast store of negative energy. Enough to ensure that everything adds up to zero.

There is no picture- or theory-independent concept of reality.

redefining the goal of science: our aim is to formulate a set of laws that enables us to predict events only up to the limit set by the uncertainty principle.

If nature is governed by laws, three questions arise: What is the origin of the laws? Are there any exceptions to the laws, i.e., miracles? Is there only one set of possible laws?

The success of A Brief History indicates that there is widespread interest in the big questions like: Where did we come from? And why is the universe the way it is?

our goal is nothing less than a complete description of the universe we live in.

We are lucky to live in an age in which we are still making discoveries….The age in which we live is the age in which we are discovering the fundamental laws of nature.

philosopher of science Karl Popper has emphasized, a good theory is characterized by the fact that it makes a number of predictions that could in principle be disproved or falsified by observation. Each time new experiments are observed to agree with the predictions, the theory survives and our confidence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory.

Thus the possibility of time travel remains open. But I'm not going to bet on it. My opponent might have the unfair advantage of knowing the future.

Most laws of nature exist as part of a larger, interconnected system of laws.

If you like, you can say that the laws [of nature] are the work of God, but that is more a definition of God than a proof of his existence.

Die wachsende Fähigkeit der Menschheit, das Universum zu verstehen, hat einen kleinen Winkel der Ordnung in einem zunehmend der Unordnung verfallenden Universum geschaffen.

But real science can be far stranger than science fiction, and much more satisfying.

People have always wanted answers to the big questions. Where did we come from? How did the universe begin? What is the meaning and design behind it all? Is there anyone out there? The creation accounts of the past now seem less relevant and credible. They have been replaced by a variety of what can only be called superstitions, ranging from New Age to Star Trek. But real science can be far stranger than science fiction, and much more satisfying.

So what does this mean in our quest to find out if there is a God? It means that if the universe adds up to nothing, then you don't need a God to create it. The universe is the ultimate free lunch.

An asteroid collision would be something against which we have no defence. The last big such collision with us was about sixty-six million years ago and that is thought to have killed the dinosaurs, and it will happen again. This is not science fiction; it is guaranteed by the laws of physics and probability.

Segundo algumas teorias, o universo que vivenciamos é apenas uma superfície quadridimensional em um espaço com dez ou onze dimensões. O filme Interestelar dá uma ideia de como isso funcionaria. Nós não veríamos essas dimensões extras porque a luz não se propagaria por elas, mas apenas pelas quatro dimensões do nosso universo.

The basic assumption of science is scientific determinism.
