What is the golem? In Jewish mythology the Golem is an effigy or image brought to life. While not evil, it is a strong, clumsy and incomplete servant. Through a series of case studies, ranging from relativity and cold fusion to memory in worms and the sex lives of lizards, Harry Collins and Trevor Pinch debunk the traditional view that science is the straightforward result of competent theorization, observation and experimentation. Scientific certainty is the interpretation of ambiguous results. The very well received first edition generated much debate, reflected in a substantial new Afterword in this new edition, which seeks to place the book in what have become known as 'the science wars'.
