Windmills And How They Became A Dutch Icon

One of the first images that comes to mind when people think of Holland, no matter where they are from, is a windmill. Funny enough, windmills are not a Dutch invention at all. So how come they ended up as an icon for everything Dutch?
The first windmills were probably invented by the Greek. We know that the Greek Tesibius, who lived from 285 to 222 BC, was probably the first who experimented with the idea of using wind instead of water to drive a mill.
We also know that the Persians had windmills for grinding grain, during the 940s, although historians suspect that they may have existed in the area already in the 700s. These were fixed mills that could not turn to follow changing winds. Only if the wind was blowing from a certain direction the mills could be used.
Windmills first pop up in Europe during the 1000s and 1100s in Flanders and Normandy. These were also fixed mills and mainly used for grinding grain.
Around 1180, we find the first documented rotating windmills in Flanders, also known as post mills. These mills were a technical revolution because they allowed the miller to follow the wind by turning the upper part of the mill, hence making more and better use of it. During the 1200s and 1300s, the post mill spread around Europe and could be found from Scandinavia in the North to Bulgaria and Turkey in the South.
By the 1400s, post mills were a very common sight in almost every part of Europe. So what happened that nowadays people associate windmills so specifically with the Netherlands? Cynics may say that this is mostly the result of the promotional efforts of the Dutch Bureau for Tourism. And although they have put a lot of effort in promoting an image of tulips, cheese and windmills overseas, they did not invent these icons. They merely took and emphasized icons that were already there.
The fame of the Dutch windmills probably started in the 1600s because of a man called Cornelis Corneliszoon van Uitgeest, who lived from about 1550 to about 1607. He had a brilliant idea: he added a crankshaft (an Arabic invention, by the way) to a windmill to convert the rotating movement to an up and down movement. This way a windmill could be used to saw wood at a significantly higher speed than any experienced hand sawing team at the time. He obtained a patent for his invention in 1593. A very lucky timing because already in 1602 the Dutch East India Company was founded to explore the East Indies. As a consequence, the demand for wood to build ships grew explosively during the decades to follow.
Sawing mills were implemented en masse to supply the tons of wood Amsterdam’s shipyards devoured each year. The first sawing mills however, were not build near the Amsterdam shipyards but along the river Zaan north of Amsterdam. The reason for this is that the hand sawing guilds of Amsterdam, feeling threatened by the sawing mils, managed to ban them from the city. Therefore, they were built just outside Amsterdam’s borders were the guilds had no power and the wood was simply shipped to Amsterdam over the river Zaan.
Cornelis’ patent expired in 1610 and shortly after the amount of sawing mills grew explosively. In a couple of years, almost 90 mills arose in the province of Holland of which 53 were located in the Zaan area. Once it became clear that the ban on sawing mills could not save the hand sawing industry, the ban was lifted in 1630 and the amount of sawing mills grew even further. Historians believe that at the peak of the wind mill era, over 1000 mills were operating in the Holland province. This was using wind power on an industrial scale, especially considering that the Holland province has a land area of only 2,670 km2 (or 1,030 sq mi). Add to this all the mills used to pump water to keep the reclaimed land dry, and it becomes clear that nowhere in Europe windmills were so prominent in the landscape as they were in Holland. Some historians have even theorized that the Dutch jumped on the Industrial Revolution train somewhat late because they already had an industry going powered by wind and hence did not feel the need to switch to steam. Along the same lines the Dutch adopted the train rather late because they had a good transportation network in place using canal boats.
Nowadays little windmills are left in the Netherlands, the most famous being those at the Zaanse Schans. Industry and pumps to keep our feet dry are now powered by electricity. However, we are perhaps slowly reaching back to our windmill days. Over the last two decades, more and more modern wind turbines have been installed in an effort to produce clean power. Slowly, wind turbines are reclaiming the landscape the wind mills dominated for centuries hence redefining on of our best known icons.
Freedom Of Speech

If there is one thing the Dutch deeply cherish it is freedom of speech. We like to speak our mind and don’t worry about being seen as utterly blunt by non-Dutch. It’s a right so dear to us that through history we have gone through great lengths to obtain and protect that right. Because freedom of speech is the driving force behind social evolution. The possibility to ponder new thoughts aloud without fear of being burned at the stakes makes it possible to find new and better ways to live our lives. The problem is however, that any new thought is usually is some way insulting because it questions the status quo.
If everybody “knows” that the Earth is flat and the sun and planets all circle around it, suggesting that in fact the Earth is round and that it revolves around the Sun along with the other planets challenges the status quo. It offends. Tell Galileo Galilei about it. The Church condemned his brilliant ideas, prohibited their publication, and sentenced Galileo to lifetime house arrest in 1633. And yet, Galileo was right. It took the Church 360 years to apologize and admit that Galileo was right after all.
Martin Luther run into trouble with the authorities as well, because he had a different view about the relationship between man and God. His ideas challenges about everything the power of the Church at that time was based on. His ideas were seen as highly offensive and he was banned by the Church. However, today his ideas are much appreciated by a large worldwide Protestant community.
The suffragettes dared to speak out loud about the right to vote for women. They were ridiculed at first, but as their ideas took hold among women in society they were imprisoned. Fierce action was taken to make them shut up, literally. Why? Because their ideas were offensive to men. It was though to be ridiculous and dangerous for women to pretend being as smart as men. Some women even died for the cause. And yet, because they spoke out, women can now vote, work and do all those things their great-grandmothers could not.
These are just a few examples of how ideas that were thought to be offensive at first, changed our society in positive ways, made us move forward as mankind. Censorship puts social evolution on hold or even shuts it down. We may not always like to hear about ideas that very much do not coincide with our own. Nevertheless, as a society we need them. We need these new ideas, we need to discuss them out and aloud, where everybody can hear them and freely put them against their own judgment. That is why we need freedom of speech and that is why we need to cherish it.
Today many websites are going black to protest against the so-called SOPA/PIPA act that many fear will give the American Authorities far too much power to block content on the Internet. Although Internet piracy needs to be addressed, giving the State the power to play censor is probably the worst way to accomplish that. Taking sites off line will not stop piracy, but it does pave the way to censor the Internet to stop free voices that are considered inconveniently offensive to certain groups. Shutting these voices down will eventually do more damage than letting them debate out in the open. So history learns us.
On a more day-to-day basis if this bill passes the following could happen:
I always take a picture from Wikimedia to illustrate this blog, since these are copyright free images. Now if something went wrong and somebody accidentally (or intentionally) posted copyrighted material on Wikimedia whitout saying it is, and I would include that copyrighted material into this newsletter by accident, theoretically my website could get blocked, as would my business PayPal account. This would mean the end of my business since most of my readers and clients are based in the United States. The really scary thing is that they could have me blocked without ever setting foot in a court room. All the copyright owner has to do is write a letter and prove I linked to their material without paying for it. This gives room for very nasty practices to get foreign competition shut down with a little bit of creativity.
So if you are an American reading this consider to speak out against this bill so they can come up with a better, more effective and more just way to fight Internet piracy. You can do so at: http://americancensorship.org/. If you support this bill, take no offense by me worrying about it. I’m just speaking my mind and do respect you speaking yours ;o).
The Quest For The Perfect Clock

For long sundials were the best way to measure time.

As I was watching the countdown towards the New Year on my TV my thoughts wandered off to my ancestors who did not have (nor needed, perhaps) such exact timing available to them.
In fact, for centuries the only way to tell the time more or less accurately was using a sundial. The only problem with sundials is that you need, well, the sun. So what to do on cloudy days and at night? To solve this issue people used water clocks. This is a system that uses a regulated flow of water from one basin to another to measure time. During the Middle Ages church bells were used to communicate time measured by the church with sundials and water clocks to the congregation. In a time where the pace of life did not require any time measuring more accurate than telling the hours, this sufficed. After all, what medieval peasant would worry about milking her cows at 6:00 or 6:10 in the morning?
However, during the Renaissance, measuring time precisely became an obsessive quest, not because peasants demanded to be able to milk their cows at 6:10 exactly, but because it was instrumental in determining one’s exact position at sea. Up until the 1400s people had sailed the seas mostly along the cost. Not only because they were afraid to sail off the world as they thought it to be flat, but also because of the fear of seriously getting lost. After all, there was no way of telling how far the coast was once the land was out of sight.
Already in the 1300s some mechanical clocks were constructed, but they were hopelessly inaccurate and needed daily fine tuning with a sundial. It was the Dutchman Christiaan Huygens, who came up with the first pendulum clock in 1656. The pendulum clock proved to stay accurate for several days in a row, a huge achievement at the time. He perfected his clocks with inventions such as the balance wheel. That it was a Dutchman who came up with an accurate clock is not surprising. At the time, the Dutch Republic was in fierce competition with the English to control the sea routes to the East Indies. Any technology that would give either party a way to measure the longitude at sea would be instrumental in beating the competition. No wonder huge prizes were offered to anyone that could build such a seaworthy clock. However, Huygens never managed to get his clocks to work properly at sea where the rough movements of the ship would mess up the pendulum system easily. It was the Englishman John Harrison who eventually did so in 1736.
For the ordinary people, though, measuring time exactly did not become an issue until the arrival of the railway. In the Netherlands, the railway had spread countrywide around the 1850s. Only then it became apparent that towns in the East of the country were using a different time. At first, extensive timetables were used to inform passengers of the several local times involved. Since this still did not solve all the confusion and inventions such as the telegraph made time differences even more annoying, it was decided in 1909 to introduce a national standard time that became known as Amsterdam Time, which was UTC+00:20.
In 1940, the Nazi regime that occupied the Netherlands introduced Berlin Time, which is UTC+01:00. They also introduced daylight saving time. After the liberation of the Netherlands in 1945, the time was not set back to Amsterdam Time. So even today the Netherlands is still on Berlin Time, and still uses daylight saving time, although the debate about the latter is increasing over the last couple of years.
However much comfort this exact measuring of time has given us, I sometimes wonder if our ancestors were not privileged after all to not have a demanding agenda and an unrelenting exact clock determining their every move. Perhaps a good idea for the new year is to toss our clock and agenda out of the window once a month and live a day at the pace of our ancestors. Happy 2012!
