About Time - Chapter 12 - Atomic time
Where for thousands of years the intricate dance of the heavenly bodies served as a perfectly suitable measure of time we have currently turned to the miniscule movements of atoms to dictate the chronological rhythm of our lives. Since the beginning of our story the scope of our experience of time has greatly expanded while we have learned to measure its passing with ever greater accuracy. While for our ancestors time seemed cyclical and mysterious, it is now linear and measurable.

About Time - Chapter 11 - Universal time
The discovery of the Americas in the 15th century would start an age of exploration when Western cultures would expand their empires across the world’s oceans. Traversing these vast stretches of sea was a navigational challenge that would eventually be overcome by the introduction of mobile precision timepieces. Their development was rapid and they would soon feature minutes and even seconds. However, up until the 19th century the stationary clock and bell towers would still show or sound a local time that could easily disagree with the local time of a nearby village.

About Time - Chapter 10 - Heliocentric time
Since the rise of astrology, priests had been observing and interpreting the motions of stars and planets for religious purposes. But others developed an interest that would be more accurately described as scientific. So-called ‘astronomers’ had a passion for empirical observation and meticulous measurement. Over time they built up an extensive database describing the celestial realm. Enabled by all this data and the invention of the telescope, progress was further fueled by new mathematical insights and the ability for ideas to develop and spread rapidly thanks to the founding of universities and the invention of the printing press.

About Time - Chapter 8 - The calendar
The Mesopotamians, Egyptians and Greeks had made important contributions to measuring time based on the motions of the Sun and Moon. Although impressive feats and serving the purpose of navigating seasonal activities, none of these early methods were very accurate in the long term. Over time the growing complexity of societies increased the need to organize the diversity of social activities in a more accurate and uniform model of time reference.

About Time - Chapter 7 - The week
To further organize their lives, various cultures would adopt differing versions of an artificial, smaller cycle of days, independent of the rhythms of nature. The Babylonians had cut their month into portions of seven days, of which the last day was seen as unfortunate. These days were named after the Sun, the moon and the five known planets, which had attained a Godlike status. Because like the Sun and moon had clearly proven, it was believed that the planets must also possess powers to profoundly influence our lives.

About Time - Chapter 4 - The future
Our foraging ancestors possessed an extensive store of ready, natural knowledge. Recognition of the seasons increased our understanding of the growth cycles of plants, when to plant their seeds and when to harvest them. This allowed us to cultivate crops on a large scale, which required us to stay close in order to take care of them. Slowly we exchanged our roaming lifestyle for a sedentary one, living in service of our crops.

About Time - Chapter 3 - The seasons
Driven by the Sun, early man spent his days on the move; roaming, hunting and gathering food. We followed pleasant temperatures, weather and the presence of water, animals and plants. Our movements were guided by the state of our surroundings, which seemed to change with the shifting length of daytime. At night, when the earth turned dark, our gaze turned up towards a blanket of tiny twinkling lights.

About Time - Chapter 2 - The day
Time is change. And to our early ancestors this change was cyclical and repetitive. We lived from day to day in the mysterious, measureless now without the need to plan ahead very far or look back. There were no units of time as we know them now, let alone a calendar to order them in. Concepts like ‘next week’ or ‘last year’ simply did not exist. Our sense of time was limited to the endless cycle of light and darkness.

About Time - Chapter 1 - The mystery of time
Since the dawn of mankind, people have wondered about time. We all experience its passing, at least for the short period of change between birth and death. This feared briefness may well explain our distinctive fascination with time compared to other species. The only time we ever really seem to perceive is the present, which seems to flow forward, locked in between the two eternities of past and future.
