In order to understand the origin of the universe, one therefore has to incorporate the Uncertainty Principle into Einstein's general theory of relativity. This has been the great challenge in theoretical physics for at least the last thirty years. We haven't solved it yet, but we have made a lot of progress.

and energy, it would have taken an infinite amount of energy to get it there. For this reason, any normal object is forever confined by relativity to move at speeds slower than the speed of light.

Evolution has ensured that our brains just aren't equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it's just as easy to think in 11 dimensions, as it is to think in three or four. Stephen Hawking

Economics is also an effective theory, based on the notion of free will plus the assumption that people evaluate their possible alternative courses of action and choose the best. That effective theory is only moderately successful in predicting behavior because, as we all know, decisions are often not rational or are based on a defective analysis of the consequences of the choice. This is why the world is in such a mess.

The laws of physics demand the existence of something called 'negative energy'.

Newton sangat khawatir dengan tiadanya posisi mutlak atau yang disebut ruang mutlak (absolute space), karena tidak cocok dengan gagasannya mengenai Tuhan yang mutlak. Dia malah menolak menerima ketiadaan ruang mutlak, walau hukumnya sendiri menyatakan demikian.

Namun teori relativitas memaksa kita mengubah secara mendasar gagasan kita mengenai ruang dan waktu. Kita harus menerima bahwa waktu tidak sepenuhnya terpisah dari ruang, tapi malah berpadu dengan ruang untuk membentuk objek bernama ruang-waktu (space-time).

Dalam teori relativitas tidak ada waktu mutlak yang unik; tiap individu punya pengukuran waktu sendiri yang bergantung kepada tempat dan cara kerjanya.

Teori relativitas umum Einstein menyiratkan bahwa alam semesta harus punya permulaan dan, mungkin akhir.

Einstein was awarded the Nobel prize for his contribution to quantum theory. Nevertheless, Einstein never accepted that the universe was governed by chance; his feelings were summed up in his famous statement, 'God does not play dice.

In the theory of relativity, if one can travel faster than light, one can also travel back in time, and this would lead to problems with people going back and changing the past. One would also expect to have already seen large numbers of tourists from the future, curious to look at our quaint, old-fashioned ways.

Stephen Hawking

I think that there is a good chance that the study of the early universe and the requirements of mathematical consistency will lead us to a complete unified theory within the lifetime of some of us who are around today, always presuming we don't blow ourselves up first.

However, if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason – for then we would know the mind of God.

The originator of an idea cannot be held responsible for egregious misuse of his theory.

Being exposed to theory, stimulated by a basic love of concepts and mathematics, was a marvelous experience.

I was a teacher for a long time. I taught at a community college: voice, theory, humanities. And nowadays, music education is a dying thing. Funding is being cut more and more and more.

The two leading ethical theories in Western philosophy were founded by men who were as high as could be on systemizing, and were rather low on empathizing.

attachment theory, a well-supported theory that describes the system by which mothers and children regulate each other's behavior so that the child gets a good mix of protection and opportunities for independent exploration.6

as 'an explanation of ignotum ab ignoto'"—a theory that relies on the unknown to explain the unknown.

Give every data point the attention and scrutiny it deserves, and keep an open mind for alternative explanations that may explain your observations as well as (or better than) your pet theories.

This is, more or less, what the great twentieth-century philosopher of science Karl R. Popper and his followers have called the principle of falsifiability. Science is distinctive, not because it proves true statements, but because it seeks systematically to disprove (falsify) false ones.

If there is such a thing as media theory, there should also be format theory. Writers have too often collapsed discussions of format into their analyses of what is important about a given medium. Format denotes a whole range of decisions that affect the look, feel, experience, and workings of a medium. It
