He called these things "relative time" and they were the only concepts we could grasp as a species.

The other side of the coin is a theory posed by two famous philosophers by the names of Gottfried Leibniz and Immanuel Kant. This secondary theory is more simplistic, it simply holds to the belief that time is not a thing or a place.

Given this truth, it cannot be measured accurately or traveled through. Chronometry is the science of measuring time and it comes in two different forms: the calendar and the clock. When seeking to measure a length that is less than a day, the clock is used. Measuring something that is longer requires the use of a calendar. Let's examine how these two fundamental tools came to be.

The first calendars were used as early as 6, years ago, based on artifacts discovered from the Paleolithic era, and were dependent on the phases of the moon. Known as lunar calendars, these early versions had between twelve and thirteen months to each year. These calendars weren't entirely accurate, however, because they didn't account for the fact that a year is roughly Calendars measure days in whole numbers so a method called intercalation was introduced that adds a leap day, week, or month into the calendar when needed to keep the measurements accurate.

Julius Caesar decreed in 45 B. C that the Roman Empire would use a solar calendar and it became known as the Julian calendar. This version still suffered from a lack of accuracy because the intercalation it used caused the annual solstices and equinoxes to throw off the measurements by as much as 11 minutes per year. This was known as the Gregorian calendar and it is now the most commonly used version today.

Horology is the study of devices used to measure time. This pursuit dates back to BC when the Egyptians created the first sundial. This stationary device uses a shadow cast by the sun to measure the passage of hours throughout the day. These devices were accurate only during the day however. A more accurate solution was something called a water clock that was also used by the ancient Egyptians.

The actual origin of these devices is not known, but along with sundials these were the first tools used to measure time. The water clock functioned by creating a set flow of water that could be used to measure the passage of time.

It required constant maintenance though, otherwise the water would run out. Many ancient civilizations were very focused on keeping accurate measurements of time because they used it to track their astronomical findings.

Water clocks were used consistently until the middle ages. The use of incense, candles and hourglasses were also prevalent. While mechanical clocks did make an appearance as early as the 11th century, it wasn't until new methods like the pendulum clock were made by individuals like Galileo Galilei and Christiaan Huygens that they became reliable. Today the most accurate tool for measuring time are atomic clocks.

These incredible devices can maintain a pitch-perfect accuracy for millions of years. They are so accurate in fact, that they are used to set other clocks and GPS systems. Instead of using mechanical or repetitive methods, these clocks measure atoms as incredibly low temperatures.

It is located in the National Institute of Standards and Technology. This clock's accuracy means that it won't be off by a single second for at least million years.

This is all based on the internationally defined standard for what constitutes a single second :. By measuring these caesium atoms at incredibly low temperatures, atomic clocks can track time almost perfectly based on this established standard.

Our modern society requires us to have a set standard for how we measure time. The most basic means of doing this is known as International Atomic Time TAI and measures seconds, minutes, and hours by coordinating atomic clocks around the world.

These intellectual property concerns are of course real and important, but they risk blocking any open innovation initiative from gaining momentum. However, during the Covid crisis it could be wise to focus more on creating value than capturing value. Smart companies take a leap of faith, collaborating on important stuff, without risking negative exposure. As the initial open innovation enthusiasm has settled, companies often realize that they rely on voluntary and active participation of employees and partners to succeed — traditional means of command and control have little reach.

Instead companies need to rely on a combination of hard and soft incentives to motivate internal and external collaborators. For example, our own research on open-source software development has demonstrated a diverse set of motivations among developers.

Some developers are motivated to freely share their code because of labor market signaling. Other developers are driven by strong ethical concerns, vigorously opposing any move to develop software that cannot be inspected, modified, and openly shared. And some companies are motivated to donate time and resources because it is an effective means to access complementary skills and assets. Aligning all of these motivations with what companies wish to achieve takes effort, curiosity and a portion of humbleness.

A common challenge in open innovation is to take on new partners. New partners always entail costs in terms of search, validation, and compliance, as well as the forming of new social relationships between people. And we know that when it comes to big thorny problems like Covid, new partners are necessary to provide complementary skills and perspectives.

The massive scale of the Covid crisis may have alleviated these challenges in at least two ways. First, top management has assumed a lot of the risk associated with new partners, by sending strong messages that open innovation is the way to go. Second, not only the spread of the virus has grown exponentially but the pool of potential partners as well. When companies across the globe are affected by the same crisis, and many are searching for new ways to conduct business, a combinatorial exercise suggests that there are many better partners available now than a month ago.

A crisis can prompt companies to explore a greater number and even new kinds of partners. Preserving some of that open-minded attitude towards new partners after the crisis can help companies stay on top of innovation. For example, hire some consultants, set up an innovation tournament, wait for ideas to come in.

The results though are usually quite meager.
