Why is astronomy considered a science while astrology is considered only a pseudoscience?
In other words, how can we prove that a theory faithfully describes reality,
and that this theory can then be used to predict unknown facts? Karl Popper, the
well-known philosopher, studied these problems and summarized his conclusions in
one...
“Which digital camera should I buy? What is the best holiday for me and
my family? Which is the best investment for supporting the education of my
children? Which movie should I rent? Which web sites will I find interesting?
Which book should I buy for my next vacation? Which degree and university
are the best for my...
The iPad 2 and the original iPad, taken together, are the biggest thing to
hit computing in years. Drawing on the best of Apple’s iPhone and iPod
touch products, and Apple’s Macintosh personal computers, while introducing
a whole new way of seeing and interacting with information, the
two new devices have grabbed the...
Crystallization from solution is a core technology in major sectors of the
chemical process and allied industries. Crystals are produced in varying sizes
ranging from as small as a few tens of nanometers to several millimetres
or more, both as discrete particles and as structured agglomerates. Well-
established examples include bulk...
The IBM i operating system running on IBM Power Systems is a platform in transition.
Many think the system is obsolete, largely due to its infamous green screen. Nothing,
though, could be further from the truth. When IBM embraced open-source software such
as Linux, MySQL, and Zend PHP, the system cemented a formidable position in...

done. Many people pick up a piece of paper every day and write down the things they want to

their heads, but as we get older, we need to...
I first met Peter Plesch in the late 1950s when he had established his vacuum techniques
in Keele and I was embarking on my PhD. My visit to Keele was to seek advice (freely
given) on handling sensitive reaction systems. I rapidly came to appreciate that Peter
operated on a somewhat higher intellectual plane than many academics. All...
The recognition that chemicals in food, whatever their origin, might
present a risk to the consumer has long been recognised. However, early
food regulations at the beginning of the century were primarily aimed at
prevention of adulteration and fraud rather than directed at consumer
safety. It is only in the second half of the century...
The World is confronted with a plethora of potentially disruptive technologies
– some, such as nanotechnology, will inevitably challenge our cherished
social, economic and industrial stability over the next two decades. Rational
design and manufacture of materials properties through nanostructure control
will profoundly...
Society today, writes Stephen Post, is "hypercognitive": it places inordinate emphasis on people's powers of rational thinking and memory. Thus, Alzheimer disease and other dementias, which over an extended period incrementally rob patients of exactly those functions, raise many dilemmas. How are we to viewâand...
