INVENTION: Ideas that changed the world

THERE is one historical factoid that simply blows my neo cortex and will probably continue to astound me until the day I die. It is perhaps more of a hypothetical than anything else and begs the age-old question of “what if?”

Roman Cage Cup from the 4th century A.D.

Around 100 BC European cultures started to become increasingly fond of their favourite drink, wine, as they perfected its creation and associated it with wealth and prosperity. The beautiful colour of wine, its taste and scent became such an obsession that the Romans­ started to discover better ways to preserve their fermented elixir.

Thus, glass entered our world, and resulted in a chain of invention that is still being advanced today. Glass led to lens grinding and spectacles, meaning that intellectuals and scientists had an extra 15 to 20 years of reading and active life. Microscopes came into play, which led to the discovery of micro-organisms, including the discovery and behaviour of the bacterium.

On a larger scale, telescopes gazed outwards, allowing humankind to further its knowledge of our galaxy and the Earth’s place within it. And because glass is chemically neutral — meaning that it doesn’t react to anything that’s in it — chemicals could be mixed in glass beakers and flasks. This advanced chemistry and modern medicine to new levels.

This is not to mention plasma computer screens, cellphones, light bulbs, windows, windscreens, clocks and watches, glass domes and spaceships. Glass valves have become essential in modern electronics too and can be found in several household items that don’t have a particularly glassy feel.

And all because Europeans enjoyed their wine.

Glass bottled wineMeanwhile, on the other side of the planet, one of the most inventive people to have ever lived, the Chinese­, were quite content with the teacup. They had no interest in Western wine and used paper and ceramics as glass substitutes. Chinese windows and lanterns were all made from paper­ and the potential of glass was never recognised­ in the East due to their preference for tea.

So from the 14th century right up to the 19th century­, glass did not exist in the Eastern part of the world. While the Chinese did go on to invent a myriad of other things, it can be argued that not inventing glass held back the course of Chinese history.

Of course a lack of glass did not stop the Chinese from going on to invent other things. We have them to thank for paper, printing, gunpowder, the compass, archeology, automatically opening doors, hydraulics, the bristle toothbrush, landmines, fireworks, the fishing reel, kites, the crossbow, playing cards, porcelain, the rudder, tofu, toilet paper, the wheelbarrow, and of course, China.

Yet the thought of what may have been invented if glass has existed in China for those 500 years is staggering. The world as we know it could be a lot different today if things had panned out differently. We might all be speaking Chinese and drinking tea.

GREEN DAM: Latest Internet screening program takes its duties to farcical extremes - but China is adopting it

Green Dam uses colour and form recognition to zoom in on potential expanses of naked flesh.

BEIJING — What do Johnny Depp, Garfield, Paris Hilton and roast pork have in common? In China, the answer is that a new government-mandated Internet filter rates some pictures of all four of them as bad for your moral health.

Beijing has ordered all personal computers sold in China since the beginning of July to be preinstalled with the Green Dam software, which it says is designed to block pornographic and violent images, and which critics fear will be used to extend censorship in the country.

But a trial of the programme, which is available online for free download at www.skycn.com/soft/46657.html, suggested its filters may be of limited use to worried parents.

When the software is installed, and an image scanner activated, it blocks even harmless images of a film poster for cartoon cat Garfield, dishes of flesh-coloured cooked pork and, on one search engine, a close-up of Johnny Depp’s face.

With the image filter off, while searches with words like "nude" are blocked, a hunt for adult websites throws up links to soft- and hardcore pornography sites, including one with a video of full penetrative sex on its front page.

Green Dam has not detailed how it scans images for obscene content, but computer experts have said it likely uses colour and form recognition to zoom in on potential expanses of naked flesh.

Programme settings allow users to choose how tightly they want images scanned. When too much skin is detected, Green Dam closes all Internet browsers with no warning, sometimes flashing up a notice that the viewer is looking at “harmful” content.

But the interpretation of obscene is apparently generous enough to include the orange hue of Garfield’s fur and, on the highest security settings, prevent viewers clicking through to any illustrated story on one English news site.

The software also allows users to choose what they want to filter for, and besides adult websites and violence, categories include “gay” and “illegal activities”.

Another setting allows Green Dam to take regular snapshots of a user’s screen and store them for up to two weeks — ostensibly so parents can monitor computer use by minors.

But it could also potentially leave security officials a track of computer use by a suspected dissident, or be a gift to fraudsters who are on the hunt for online bank details and private information.

Western governments and trade groups have asked China to reconsi­der implementing Green Dam software based on concerns ranging from cyber-security and performance of the software to Internet freedoms.

News update: Dalai Lama is free to visit SA any time! - iol.co.za

AN activist group called Avaaz is rallying support to allow the Dalai Lama entry into South Africa before the 2010 World Cup. You can sign an online petition to South African President Motlanthe below to help reverse his decision not to allow the Dalai Lama entry into the country for political and economic reasons.

Dear South African friends,

Dalai LamaDespite its denial this week, our government appears to have refused the Dalai Lama an entry visa because of fears it may affect the burgeoning trade relationship with China. Archbishop Desmond Tutu has called this act a "total betrayal of our struggle's history" and along with other Nobel laureates including FW de Klerk has announced he will boycott the World Cup peace conference, which the Dalai Lama was planning to attend before it was postponed.

Generations of South Africans fought long and hard for cultural respect, political equality and democracy in this beloved country. They struggled hand in hand with friends around the world for freedom.

We appeal to you to sign the petition to President Motlanthe reminding him that the New South Africa is a country built on solidarity and calling on him to safeguard our sovereignty from unwanted Chinese government intervention. If enough of us sign, our voices will be heard by the President to reverse his decision and allow the Dalai Lama into the country before the World Cup.

Our government has refused a visa to one of the most revered figures of our times, the Dalai Lama, because of fears it may affect trade with China.

South Africans have a proud history that must not be bargained away. Global solidarity and international leadership were instrumental in the demise of Apartheid. While economic ties with China have grown, culminating in last year's undisclosed agreement between our two countries, this opportunity should not come at the expense of human rights or support for one of the world's leading lights of peace and non-violence.

The Dalai Lama has been campaigning non-violently for autonomy for the Asian nation of Tibet from China for more than 50 years. Denying him a visa will weaken the resolve of other nations to stand up for human rights. It will certainly not serve the interests of South Africans.

Almost a century ago, Mahatma Gandhi was thrown off a train in South Africa because of Apartheid abuse. We must appeal to our government not to mete out similar disrespect to one of the most revered international figures of our times. A Chinese official has admitted that they asked South Africa not to grant the visa citing the danger it would do to their bilateral relationship; the South African government has in turn said “it would not be in the interests of South Africa” to allow the Dalai Lama in.

Let's together let our President know that abandoning an international human rights struggle for a trade relationship is a rejection of South African history, and unacceptable for the South Africa of today. This recent visa decision comes on the back of the South African government blocking vital UN Security Council decisions which would have encouraged human rights and democracy in Zimbabwe and Burma.

Now China appears to have been successful in telling our government who should and should not enter South African territory. This sets a dangerous precedent and we must appeal to the President of South Africa not to bow down to bullying tactics. As we commemorate the 50 year anniversary of the Dalai Lama being forced to flee his home in Tibet, let's together call upon the government to issue a visa to enter the land known internationally for its commitment to political freedom and human rights.

With hope,
