Beware surfers: cyberspace is filling up - Times Online
-
It will initially lead to computers being disrupted and going offline for
several minutes at a time. From 2012, however, PCs and laptops are likely to
operate at a much reduced speed, rendering the internet an “unreliable toy”. -
In America, telecoms companies are spending £40 billion a year upgrading
cables and supercomputers to increase capacity, while in Britain proposals
to replace copper cabling across part of the network with fibreoptic wires
would cost at least £5 billion. - 1 more annotations...

Study: Digital universe and its impact bigger than we thought
Bits Bytes, Atoms and Quantums
-
by 2011, the amount of electronic data created and stored will grow to 10 times the 180 exabytes that existed in 2006, reflecting a compound annual growth rate of almost 60%.
-
by 2023 the number of stored bits will surpass Avogadro's number, which is the number of carbon atoms in 12 grams, or 602,200,000,000,000,000,000,000 (6.022 x 10^23).

Mummy, that robot is making faces at me - tech - 29 October 2008 - New Scientist Tech
-
Robotics engineers at the University of Bristol, UK, have been grimacing a lot recently, thanks to their copycat robotic head, Jules, which can mimic the facial expressions and lip movements of a human being.
'Digital dark age' may doom some data

The framed photograph will inevitably fade and yellow over time, but the digital photo file may be unreadable to future computers – an unintended consequence of our rapidly digitizing world that may ultimately lead to a "digital dark age," says Jerome P. McDonough, assistant professor in the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign. - 2 more annotations...

The time for social evolution

This is because cell divisions in males increase with age. “Every time there
is a cell division, there is a chance of a mistake, a mutation, an error,”
he said. “For a 29-year old father [the mean age of reproduction in the
West] there are around 300 divisions between the sperm that made him and the
one he passes on – each one with an opportunity to make mistakes. - 2 more annotations...

Year Million: Science at the Far Edge of Knowledge
-Year Million: Science at the Far Edge of Knowledge

-
A million years, or 40,000 generations, is a long time — but not that long on a cosmic timescale. As Broderick puts it, the number is an emblem of a remote future.

理论的终结:数据洪流让科学方法变得过时 - 译言翻译

谷歌的奠基哲学就是“我们不知道为什么这张网页比那张网页好”:只要引入链接的统计数据说明它好就行了,并不需要语义上或者是因果关系的分析。这就是谷歌不需要掌握一门语言就能翻译的原因(只要给以合适的文集数据,对于谷歌来说,把外星语(原文是Klingon,克林贡语)翻译成波斯语就和把法语翻译成德语一样容易)。这也是谷歌能在没有任何知识、对广告内容没有任何了解的情况下,能把广告和内容融合得这么好的原因。

现在,生物学也向同样的方向发展。我们在学校所教的“显性和隐形基因严格遵循孟德尔法则”的模型已被证明是比牛顿定律更简单的对事实的描述。基因蛋白质交感(gene-protein interactions )和其他实验胚胎学的发现已经动摇了“DNA就是命数“的看法,甚至引入了“环境可以影响遗传特性”这些曾经在基因学上被认定为不可能的事情。简而言之,我们对生物学学得越透彻,我们发现自己离能解释生物的模型越远。
