A new problem has appeared with the mobile phones in Austria-they may end up as a mountain of poisonous waste, said the newspaper Standard on Wednesday.
The paper pointed out that Austria had one of the world's highest mobile phone densities.
The eight million Austrians shared ten million"mobiles".But four million of the mobile phones were no longer used and just lying about.
It could be dangerous if they, and the millions more after them, were thrown in the waste material, warned Karin BuechlKrammerstaetter of the Vienna Environment Office.
"Ten million mobiles have 700 tons of accumulators, and in the long term that means 700 tons of dangerous waste."
"Accumulators contain numerous substances dangerous to health and the environment, such as the heavy metal cadmium which is poisonous and classified as causing cancer,"said the environment expert. She made an appeal to the public not to throw their old mobile phones away.
"In the end the accumulators will get to a garbage depot or incinerator. From there the harmful substances will reach the environment, because depots and incinerators are not suited to the disposal of dangerous waste."
BuechlKrammerstaetter pointed out that shops selling mobile phones were limited by law to accept the accumulators of old ones back without charge, and see they were properly disposed of.

The human brain contains, I am told, 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with humanlike ability, but now that we have grown used to moving forward at such a pace we can be less sure.
Quite soon, in only 10 or 20 years perhaps, we will be able to fit together(assemble) a machine as complex as the human brain, and if we can we will. It may then take us a long time to cause it intelligent by loading in the right software or by changing the architecture but that too will happen.
I think it certain that in decades not centuries, machines of silicon will arise first to rival and then surpass their human progenitors. Once they surpass us they will be capable of their own design. In a real sense they will be reproductive. Silicon will have ended carbons long monopoly. And ours too, I suppose, for we will no longer be able to consider ourselves the finest intelligence in the known universe.

2. silicon n.硅(14号元素，符号Si，旧名矽)
