This e-book analyzes scientificproblems in the historical past of physics, engineering, chemistry, astronomy and medication, correlated with technological functions within the social context. whilst and the way is rigidity among disciplines explicitly practised? what's the conceptual bridge among technological know-how researches and the association of technological researches within the improvement of commercial applications?

The authors clarify quite a few ways that the sciences allowed complicated modelling at the one hand, and the improvement of latest technological rules however. An emphasis at the position performed by means of mechanisms, creation equipment and tools bestows a profit on ancient and medical discourse: theories, associations, universities, colleges for engineers, social implications as well.

Scholars from diversified traditions talk about the emergency variety of considering in technique and, in theoretical point of view, target to collect and re-examine the present pondering in this topic. It brings jointly contributions from prime specialists within the box, and provides much-needed perception into the topic from a ancient standpoint. the amount composition makes for soaking up interpreting for historians, philosophers and scientists.

Heaviside used the operator pn to represent the nth derivative in a differential equation, thus transforming an nth order differential equation into an nth order algebraic one—exactly as the D-operator is sometimes taught today. Using this technique, as well as some other quite advanced mathematical methods, he revisited a result derived by William Thomson (Lord Kelvin) on modelling the transmission of telegraph signals. Kelvin had neglected the self-inductance of the transmission line (which was valid, as signalling speeds at that time were sufficiently low for inductance to be negligible), but as speeds increased, the inductance of the cable played a major role, significantly distorting the signals, much to the puzzlement of practising engineers.

Assunta Bonanno, Michele Camarca, Peppino Sapia (Italy) face a classical subject: the scientific method. The crisis of this method, due to recent experimental results, jeopardizes the bases of knowledge. The authors analyze the crisis through a historical survey of the scientific method. They try to identify the cross hybridization between science and technology in the last three centuries as a possible factor to overcome the crisis. Vito Bonifàcio (Portugal) highlights that, before the invention of cinematographe in 1895, Jules Janssen ideated a photographic revolver that permitted one to track the contact instant of 1874 Venus’ transit with precision.

Researchers at Bell Labs studied this problem in detail, resulting in the Nyquist stability criterion of 1932 and Bode’s monumental work on circuit design some years later. Karl Küpfmüller in Germany carried out similar, but rather less well-known work. Some of the most impressive, and still under-estimated, techniques involved graphical tools for design. The Nichols Chart removed the need for difficult computation of closed-loop behaviour based on open-loop modelling or experimental recording, while the Smith Chart, although it will not be discussed here, provided a similar resource for engineers concerned with transmission lines (Bissell 2012).
