International Year of Astronomy 2009 (IYA2009) initiated by UNESCO and the IAU to be Launched on January 15 and 16, 2009

As you can read at NASA, 2009 is the International Year of Astronomy, which will be officially launched on January 15 and 16 at UNESCO. This is the official logo.


UNESCO writes:

"The International Year of Astronomy will be launched at UNESCO on 15 and 16 January. This United Nations year is a worldwide celebration of astronomy, with activities in almost 140 countries. One such activity, 100 hours of astronomy for example, will bring together as many amateur astronomers as possible from around the planet from 2 – 5 April.

The Year coincides with the 400th anniversary of Galileo’s first observations with an astronomical telescope. It is an opportunity for people all over the world to rediscover their place in the universe by observing the sky at night and during the day. It is also intended to provide a platform for informing the public about recent discoveries in astronomy, while demonstrating the central role that astronomy can play in science education."

As written at Astronomy2009.org:

"IYA2009 General

The International Year of Astronomy 2009 is a global effort initiated by the International Astronomical Union and UNESCO to help the citizens of the world rediscover their place in the Universe through the day- and night-time sky, and thereby engage a personal sense of wonder and discovery.

Vision

Everyone should realise the impact of astronomy and other fundamental sciences on our daily lives, and understand how scientific knowledge can contribute to a more equitable and peaceful society. IYA2009 activities will take place locally, nationally, regionally and internationally. National Nodes have been formed in each country to prepare activities for 2009. These nodes will establish collaborations between professional and amateur astronomers, science centres and science communicators to prepare activities for 2009. Already now, 136 countries are involved and well over 140 are expected to participate eventually.

To help coordinate this huge global programme and to provide an important resource for the participating countries, the IAU has established a central Secretariat and an IYA2009 website (www.astronomy2009.org) as the principal IYA2009 resource for public, professionals and media alike."

In Germany, as reported by German Missions in the United States:

"On January 20th, the IYA 2009 in Germany will be festively inaugurated by Dr. Anette Schavan, federal minister for education and research."

What follows is the official - fantastic - video trailer for the IYA:

Europeana Online Again : European Union Relaunches its Multimillion-Euro Digital Library Experiment : Example : Oldest Illustration of Stonehenge

We posted previously about Europeana, the EU's digital library project that went online in November, 2008, only to crash the first day of operations. Today, we received news that Europeana is back online again. Here is a screen capture:

Europeana relaunch


It is accompanied by the following message:

"Europeana is back online

Thanks for registering with Europeana. The site’s online again at www.europeana.eu and we invite people who have registered to test it out. Please report anything unexpected to our Webmaster.

Many thanks for your help,
The Europeana Team"

We put the mouse on one of the photographs on that page showing that there is still some problem with the German letter ß, i.e. the "ss", which is rendered as a question mark here.

Nevertheless, to show the great charm and usefulness of such a project, we link to the oldest known illustration of Stonehenge by Lucas de Heere dating back to the 1570s (viewable in its original context in the British Public Library, Copyright © The British Library Board):

Sustainable Development Now : The ENERGY CRISIS and the continued POPULATION EXPLOSION : 2009 and Beyond : Quo Vadis Malthus?

Herve at the Blogactiv.eu blog Un peu de bon sens (A Bit of Good Sense) made the following posting on January 5, 2009. For some reason, neither Herve nor the blog are now accessible, but we found the text in Google cache. Herve's posting sets out the major problems facing humanity in the year 2009 and beyond : the energy crisis and the population crisis. Here is what Herve wrote - we repeat the full posting so it is not lost to posterity:

"In 1860, a century and an half ago, the human population was about a billion. The individual energy consumption was approximately 250 Watts (metabolism and physical work). The source of energy was then entirely renewable (the sun and its indirect by-product such as wood, wind, hydro, animal power). Anthropogenic irreversible pollution, entropy, the kind the ecosystem cannot handle, or not fast enough, was next to zero. The concentration of CO2 were about 280 ppm, CH4 (900 ppb), tropospheric ozone (10 ppb), N2O (265 ppb). At the beginning of the 21st century, the human population is above 6 billions. The global average individual energy consumption is 2500 Watts (IEA, 2007). Each human being is now consuming 10 times more. And we are 6 times more. Collectively, we require over 60 times more energy from the exact same planet. Or if we like, the same planet has to provide the equivalent energy for 60 billions of our grand-grand-parents. Individually, this is the equivalent of having 10 “energetic slave” working for us constantly. Or 3 horses. Day and night, 24/7/365. In Europe, we need over double the average, 6000 Watts (approx 25 “energetic slave”), in the US, four times the average, 12000 Watts (approx 50 “energetic slave”).

The source of energy is 85 % fossils fuels (coal 24%, gaz 21%, oil 37%), 8 % (hydro + renewable 1%), 7% nuclear (another type of fossil). The concentration of CO2 is about 387 ppm, (+ 40% since 1860, actual rate + 2.14% / year), the concentration of CH4 is about 1750 ppm. The concentration of tropospheric ozone is above 55 ppb, (+ 400 % since 1860, 2.4% /year), N2O (310 ppb).Anthropogenic irreversible pollution, is everywhere in the ecosystem, and accumulates like a poison. There is heavy metal deposition in the arctic, lead in the blood of polar bears, mercury in the oceans and in wild salmons, PCB in our flesh. Bees are threatened. We over fish. Species are disappearing at an unprecedented pace. Irrelevant externalities from an Adam Smith point of view.

The energetic intensity of our activities, the comfortable energetic armchair we are floating in with ease, are over-stretching the ecosystem. And yet, energy has become invisible. It has almost become an abstraction. We don’t see, we don’t feel this addiction. At all. We are totally unaware of these 25 energetic slaves working for us 24/7. Or are we simply uncomfortable with this truth ?We simply deny the irreversible accumulation of wastes that comes with energy, and keep hiding them under the carpet, be it nuclear waste, CO2, plastic bags. For our children to find them ? This is irresponsible. Our energy addiction -call it comfort- comes at a massive price: eroding the future of our own children.

How did we fall into the habit of needing a cart, powered by 50 horses, to go and buy a bottle of milk ? Let’s not forget that the best half of the human body is made up of legs… Not simply meant to fold under steering wheels and screens. Laziness, is this what we call progress ?

Whatever the chemical reaction, that includes any kind of combustions, the second principle of thermodynamics states that alongside this reaction, the entropy of the universe always increases. Which in our context, unless nature cleans it for us, waste accumulates. The contemporary dogma of “ever growth on cheap energy” does not fit the second principle of thermodynamics. And the law of physics are difficult to contradict very long. We cannot negotiate new ones.

Fast and Furious

Not only are we consuming more energy, but our consumption is growing faster and faster. We used as much energy between the years 1900-1950, than we used between the years 2000-05.

Then…More

By 2050, the human population is estimated to be about 9 billions (factor 1.5). According to nowadays strategies, based on an 18th century model, human activity, the economy, must grow at an annual 3% rate. In 2050, globally, this would translate into an equivalent 4 times more activity (reference year 2000). On average, if the worldwide energy intensity remains the same (optimistic scenario), still we would require between 2 and 6 times more energy globally.

This is going to be difficult to explain to our grand-children.

It is going to be difficult to explain why we have chosen to stick to an 18th century Adam Smith model, invented when pollution was neglectable and therefore relegated to an externality, by default. Adam Smith could not integrate irreversible dispersion of heavy metals in his model, because he never observed the phenomena. This understandable mistake in the 18th century, is turning into the intellectual flaw of the 21st century. Our grand children will have to correct it. They will have to refresh this old fashioned model which does not take into account accumulation of poison. As well as handle simultaneously the collapse of the ecosystem, climate change and fossil peaks.

James Watt died in 1819. Energy, thermodynamics were not even understood before the 19th century. Adam Smith died in 1790, when energy consumption was marginal. Energy not even yet a unified concept. How could he forecast the 21st century ? Schönbein discovered ozone in the 1850’s.

In the times of Adam Smith, CO2 was described as “wild spirit”. CO2, ozone, methane, energy, entropy, pollution were not discovered. They were “spiritus sylvestre”, “vis viva”. If anything, their were ghosts-like diffuse concepts. At the time of Adam Smith, regarding the ecosystem as an externality was not an ideological choice. It was just a methodological error due to limited knowledge of the times. Adam Smith could not integrate concepts that were to be invented a century later. We only started studying pollution 30 years ago.

We are counting the world with the wrong units (GDP, % of growth). Observing it with an 1750’s telescope. No wonder we keep accelerating in a U-turn, with such anachronism in mind. Where is the room for growth on this planet ? WHERE ? Which ecosystem can absorb our mistakes any longer ? Drilling for oil under the feet of the last polar bear, is this the best we can come up with ? We ought to change the unadapted striped 78 rpm disc of “perpetual growth on ever abundant cheap energy” or “growth at any cost” for a new conjunction of concepts such as stabilization, collective intelligence, survival of the next generations. In a word, sustainable development MUST become the overarching conceptual framework. NOW."
