The first camera obscura was built by an Iraqi scientist named Abu Ali Al-Hasan Ibn al-Haitham, born in Basra(965-1039 AD), known in the West as Alhacen or Alhazen, who carried out practical experiments on optics in his Book of Optics. His method of experiments is then used to establish what is know kknown as 'scientific method,' a couple of centuries before the work of Isaac Newton.

The More You Use Google, the More Google Knows About You an Investigation over at Alternet
From Google Search to Google Earth, every move you make can be tracked by some feature of Google -- and intelligence agencies are drooling over the data.Discovery that quasars don't show time dilation mystifies astronomers
The phenomenon of time dilation is a strange yet experimentally confirmed effect of relativity theory. One of its implications is that events occurring in distant parts of the universe should appear to occur more slowly than events located closer to us. For example, when observing supernovae, scientists have found that distant explosions seem to fade more slowly than the quickly-fading nearby supernovae.
What's wrong with the iPad? Let's start with the lack of a clock
My iPad arrived yesterday afternoon via a friend in the US, and yes, it largely lives up to the hype: it's shiny, elegantly realised and above all potentially very useful. Well, apart from a few wrinkles, which range from a mere raise of the eyebrows to an exasperated WTF?
