The Grand Design Quotes.

1. "La física cuántica es un nuevo modelo de la realidad que nos proporciona una imagen del universo que en muchos conceptos fundamentales para nuestra comprensión intuitiva de la realidad carecen de significado."
- Stephen Hawking, The Grand Design

2. "In physics a system is said to have a symmetry if its properties are unaffected by a certain transformation such as rotating it in space or taking its mirror image. For example, if you flip a donut over, it looks exactly the same (unless it has a chocolate topping, in which case it is better just to eat it)."
- Stephen Hawking, The Grand Design

3. "The idea of 10 dimensions might sound exciting, but they would cause real problems if you forget where you parked your car."
- Stephen Hawking, The Grand Design

4. "The human capacity for guilt is such that people can always find ways to blame themselves"
- Stephen Hawking, The Grand Design

5. "Simplicity is a matter of taste"
- Stephen Hawking, The Grand Design

6. "We believe human begins have existed for only a small fraction of cosmic history, because human race has been improving so rapidly in knowledge and technology that if people had been around for millions of years, the human race would be much further along in it's mastery."
- Stephen Hawking, The Grand Design

7. "Scientists tend to risk theories they admire"
- Stephen Hawking, The Grand Design

8. "[...] Traditionally these are questions for philosophy, but philosophy is dead. Philosophy has not kept up with modern developments in science, particularly physics. Scientists have become the bearers of the torch of discovery in our quest for knowledge."
- Stephen Hawking, The Grand Design

9. "Each exists for but a short time, and in that time explore but a small part of the whole universe."
- Stephen Hawking, The Grand Design

10. "In the early universe—when the universe was small enough to be governed by both general relativity and quantum theory—there were effectively four dimensions of space and none of time. That means that when we speak of the beginning of the universe, we are skirting the subtle issue that as we look backward toward the very early universe, time as we know it does not exist! We must accept that our usual ideas of space and time do not apply to the very early universe. That is beyond our experience, but not beyond our imagination, or our mathematics."
- Stephen Hawking, The Grand Design
