I also wish to acknowledge my grandchildren, Devyn, Bryn, Drew, Elena, Sean, and Emma, who bring great joy to my life. My wife and best friend, Diane, contributed editorial assistance, wise counsel, good humor, and the loving support that made it possible for me to accomplish a project of this magnitude. I could not have written the book without her. Religious, intellectual, and artistic activities assumed important roles in these early societies.

The focus of this book is on Western civilization, a civilization that originated primarily on the continent of Europe. Defining Western Civilization Western civilization has evolved considerably over the centuries.

Although the concept of the West did not yet exist at the time of the Mesopotamians and Egyptians, their development of writing, their drafting of law codes, and their practice of different roles based on gender all eventually influenced what became Western civilization.

Although the Greeks did not conceive of Western civilization as a cultural entity, their artistic, intellectual, and political contributions were crucial to the foundations of Western civilization. The Romans developed a remarkable series of accomplishments that were fundamental to the development of Western civilization, which came to consist largely of lands in Europe conquered by the Romans, in which Roman cultural and political ideals were gradually spread.

Nevertheless, people in these early civilizations viewed themselves as subjects of states or empires, not as members of Western civilization. With the rise of Christianity during the Late Roman Empire, however, peoples in Europe began to identify themselves as part of a civilization different from other civilizations.

In the fifteenth century, Renaissance intellectuals began to identify this civilization not only with Christianity but also with the intellectual and political achievements of the ancient Greeks and Romans. Important to the development of the idea of a distinct Western civilization were encounters with other peoples. Between and , encounters with the world of Islam helped define the West.

But after , as European ships began to move into other parts of the world, encounters with peoples in Asia, Africa, and the Americas not only had an impact on the civilizations found there but also affected how people in the West defined themselves. At the same time, as they set up colonies, Europeans began to transplant a sense of Western identity to other areas of the world, especially North America and parts of Latin America, that have come to be considered part of Western civilization.

As the concept of Western civilization has evolved over the centuries, so have the values and unique features associated with it. Science played a crucial role in the development of modern Western civilization.

The societies of the Greeks, the Romans, and the medieval Europeans were based largely on a belief in the existence of a spiritual order; a dramatic departure to a natural or material view of the universe occurred in the seventeenth-century Scientific Revolution.

Many historians have viewed the concept of political liberty, belief in the fundamental value of every individual, and a rational outlook based on a system of logical, analytical thought as unique aspects of Western civilization.

Of course, the West has also witnessed horrendous negations of liberty, individualism, and reason. Racism, slavery, violence, world wars, totalitarian regimes—these, too, form part of the complex story of what constitutes Western civilization.

The Dating of Time In our examination of Western civilization, we need also to be aware of the dating of time. In recording the past, historians try to determine the exact time when events occurred. By using dates, historians can place events in order and try to determine the development of patterns over periods of time.

If someone asked you when you were born, you would reply with a number, such as In the United States, we would all accept that number without question because it is part of the dating system followed in the Western world Europe and the Western Hemisphere. In this system, xxix events are dated by counting backward or forward from the birth of Jesus Christ assumed to be the year 1. An event that took place four hundred years before the birth of Jesus would be dated b.

Dates after the birth of Jesus are labeled a. Historians also make use of other terms to refer to time. A decade is ten years, a century is one hundred years, and a millennium is one thousand years.

Since the first century b. We could say, then, that an event in b. Since the first period of one hundred years would be the years 1 to , the fourth period or fourth century would be the years xxx to We could say, then, that an event in took place in the fourth century. Likewise, the first millennium b. Some historians now prefer to use the abbreviations b.

This is especially true of world historians, who prefer to use symbols that are not so Western or Christianoriented. The dates, of course, remain the same. Thus b.

In keeping with current usage by many historians of Western civilization, this book uses the notations b. Chip-scale atomic clocks , such as this one unveiled in , are expected to greatly improve GPS location. They can be driven by a variety of means, including gravity, springs, and various forms of electrical power, and regulated by a variety of means such as a pendulum.

Alarm clocks first appeared in ancient Greece around BC with a water clock that would set off a whistle. This idea was later mechanized by Levi Hutchins and Seth E. Initially, the term was used to refer to the marine chronometer , a timepiece used to determine longitude by means of celestial navigation , a precision firstly achieved by John Harrison. More recently, the term has also been applied to the chronometer watch , a watch that meets precision standards set by the Swiss agency COSC.

The most accurate timekeeping devices are atomic clocks , which are accurate to seconds in many millions of years, [31] and are used to calibrate other clocks and timekeeping instruments.

Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second. One of the most common atoms used is caesium , most modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations. SI defines the second as 9,,, cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the Cs atom. Today, the Global Positioning System in coordination with the Network Time Protocol can be used to synchronize timekeeping systems across the globe.

In medieval philosophical writings, the atom was a unit of time referred to as the smallest possible division of time.

It was used in the computus , the process of calculating the date of Easter. As of May [update] , the smallest time interval uncertainty in direct measurements is on the order of 12 attoseconds 1. A minute min is 60 seconds in length, and an hour is 60 minutes in length. A day is 24 hours or 86, seconds in length. The solar day is the time interval between two successive solar noons, i. The local meridian is an imaginary line that runs from celestial north pole to celestial south pole passing directly over the head of the observer.

At the local meridian the Sun reaches its highest point on its daily arc across the sky. The second is "elastic", because tidal friction is slowing the earth's rotation rate. The SI base unit for time is the SI second. The International System of Quantities , which incorporates the SI, also defines larger units of time equal to fixed integer multiples of one second 1 s , such as the minute, hour and day. These are not part of the SI, but may be used alongside the SI. Other units of time such as the month and the year are not equal to fixed multiples of 1 s, and instead exhibit significant variations in duration.

At its meeting, the CIPM affirmed that this definition refers to a caesium atom in its ground state at a temperature of 0 K.

The definition of the second in mean solar time, however, is unchanged. World time While in theory, the concept of a single worldwide universal time-scale may have been conceived of many centuries ago, in practicality the technical ability to create and maintain such a time-scale did not become possible until the midth century. The timescale adopted was Greenwich Mean Time, created in Also, it really helped my son and me to resign ourselves to not being able to visualize certain concepts.

Wave-particle duality is just plain weird, and I think it helps to do the best you can and ultimately just go with it, rather than struggling to fit this contradictory idea into a conventional kind of "making sense. Jul 11, Briynne rated it it was amazing. Wow and wow. I am not by nature a science person. The largely-repressed memories I have of high school chemistry still make me feel a little ill.

But this, friends, is more like reading poetry than it is like reading a textbook. I am officially in awe of Stephen Hawking - the man can actually make you feel about subatomic particles and forces of nature. It's nothing short of amazing, really.

A lot of this material I learned in school or absorbed over time in media and Star Trek , though the advance of years washed away much of it, but this book was easy enough for a proto-geek like myself that is like a cro-magnon scientist compared to the smarts of people I know to have some limited understanding and to enjoy, though there are still sections that are blank in my mind.

Did I read them? I am not sure. I think Hawking is just playing with me, like a mega-brain cat swatting around an insignificant cricket. Luckily, I don't think he plans on crushing me. And it was somewhat comforting to understand that, like me, the universe is still expanding. I was disheartened to learn we cannot achieve light-speed. Now, I think I will return to previously scheduled fiction maybe some fantasy. Jan 14, Anto rated it it was amazing Recommended to Anto by: I began watching Neil Degrasse Tyson's Cosmos last year and it resited my interest in learning about physics and astronomy.

While I excelled in other subjects, my physics teacher in school didn't exactly make the topic interesting so I was never really good at it. No enthusiasm engendered there.

A Brief History of Time

When I learned that there was a Briefer History of Time, I opted for that one bec I began watching Neil Degrasse Tyson's Cosmos last year and it resited my interest in learning about physics and astronomy.

When I learned that there was a Briefer History of Time, I opted for that one because of my relative ignorance in the subject. In the first chapters, I feared I should have chosen the Brief version instead, because it was kind of 4 Dummies and I didn't need that much explaining to understand it. I was still learning new concepts though, so it kept me going. Later on it gradually gained complexity with every passing chapter, but the preceding chapters prepare you well for them.

There's a certain satisfaction in knowing you wouldn't have gotten all of what you're reading if you had skipped the preceding chapters. When you think of how you would share this with other people, you realize that it would take some time because you'd need to explain from beginning to end. It's not an over-complicated book you have to waddle through and put down every 30 minutes to digest. The concepts are engaging enough and the path to them is easy and smooth.

In the end it is not at 4 dummies, you need to have read the preceding chapters to understand it if you're new to the subject. Stephen Hawking and Leonard Mlodinow wrote this in a really enthusiastic way so as a reader you will be excited too.

Well, to summarize this , as someone who started out being pretty ignorant in physics, I'm glad I had a pleasant, fun experience out of becoming better informed on a fascinating subject, including topics like Special and General Relativity, Quantum Theory, and String Theory. I recommend it to pretty much anyone over the age of 12 who doesn't know much about these subjects. This is for beginners. If you're thinking of downloading this for someone who has already been enthusiastic about this subject for a while , even if they're 13, chances are they won't get so much out of this and you should get a recommendation for the next step of depth.

However I wish explanations to some theories made sense to me. I still feel unfullfilled about string theory and multi dimensions. In addition, the language was a bit dry, or so I thought.

Still humor wasn't absent. Apart from those, I liked this book. Got good deal of information and understanding of theories. After reading sc "A briefer history of time" is briefer and simpler version of "A brief history of time".

After reading science themed books, especially ones dealing with cosmos, you can't help but feel smaller and meaningless. However it also fuels your curiosity about universe and science.

I really like popular science books and how they are great ways to understand science and even got even deeper. Jan 13, Rusty rated it liked it Shelves: To begin, I am not…. But I would like to get a better grasp on some scientific principles, so I thought I would give this book a whirl. Feb 08, S. Baqer Al-Meshqab rated it really liked it. Imagine you are a tiny particle, one that lived throughout the universe since the beginning of time.

You witnessed the dawn of creation, and within you lie the rules with which the end can be foreseen. You are fully aware of the characteristics of space-time. You could even be a string! But nobody can say for sure, for only you have that knowledge. You gaze at the human race along the path of t Imagine you are a tiny particle, one that lived throughout the universe since the beginning of time.

You gaze at the human race along the path of time, laughing: They still don't know. But you praise their efforts in their quest to understand it all. Such is the magnificence of a bewildering world. For a beginner in the field of physics, going through this book may not be an easy task. It was not, for me In spite of being relatively short, it requires a great deal of concentration.

A Briefer History of Time does not tell the story of creation, at least not entirely. It outlines, however, the scientific theories, observations, and discoveries by which one can try to understand how things are they way they are. Starting with the basic definition of the Scientific Theory, and ending with the dilemma of String Theories, the authors tackle some interesting topics regarding the nature of space and time, realized by a different set of theories initiated by different scientists; like Newton, Einstein, and Heisenberg, during a long course of human history.

They will shed some light on the big bang, the black holes, the forces that govern the universe and its components, worm holes and even time travel! Despite all that is known up to date, some things still remain a mystery.

Don't expect the book to give you a happy, clear ending, for nowadays theories are not able to explain everything, as they are still not completely compatible. The future, however, is a head of us, and we might, one day, find the one grand ultimate theory which can unveil the curtains to the unknown.

Or can we not? Mar 30, Rick rated it really liked it Recommends it for: I love Physics. And I suck at understanding Physics. But I try. I can actually identify the paragraph where I get lost.

I guess that, at least at this time in my life, I'm not capable of getting my head around the concept of a unified and relative space-time and all the implications it carries such as the bending of time near large gravitational fields, differences in aging the farther one gets from the center of a large gravitational field, and that whole section about time travel.

I really w I love Physics. I really wish I did get it, and I am confident that someday I will. As for now, even though I read the whole book after about page 70 most of it was well over my head. This is going to motivate me, though, to find someone who might be able to explain it to me so I get it.Readers also enjoyed.

Out of those four forces five if you divide electric and magnetic, but since electricity will create a magnetic force, they are effectively combined only gravity stands out. An Einstein Centenary Survey, with W. Logic doesn't appear to be Hawking's forte when it comes to seeking existential self-justification. Stephen Hawking worked on the basic laws which govern the universe. My work is about finding a rational framework to understand the universe around us.
