By Imre Lakatos
Imre Lakatos' philosophical and medical papers are released right here in volumes. quantity I brings jointly his very influential yet scattered papers at the philosophy of the actual sciences, and contains one vital unpublished essay at the impact of Newton's medical success. quantity 2 provides his paintings at the philosophy of arithmetic (much of it unpublished), including a few severe essays on modern philosophers of technological know-how and a few recognized polemical writings on political and academic concerns.

A precis of medical strategy is a short description of what makes technology medical. it's written in a right away, transparent type that's obtainable and informative for scientists and technological know-how scholars. it really is meant to aid technological know-how academics clarify how technology works, highlighting strengths with no ignoring barriers, and to assist scientists articulate the method and criteria in their paintings.
First released in 1976, this can be a quantity of reports at the difficulties of theory-appraisal within the actual sciences - how and why very important theories are constructed, replaced and are changed, and through what standards we pass judgement on one conception an boost on one other. the quantity is brought by means of a vintage paper of Imre Lakatos's, which units out a idea for tackling those difficulties - the technique of clinical study programmes.
J. D. Bernal's enormous paintings technology in heritage is the 1st full-scale try to study the connection among technology and society all through background, from the perfection of the 1st flint hand ax to the development of the hydrogen bomb. This outstanding learn illustrates the impetus given to and the constraints put upon discovery and invention by way of pastoral, agricultural, feudal, capitalist, and socialist structures, and conversely the ways that technological know-how has altered financial, social, and political opinions and practices.

Er struggle einer der führenden Pioniere der großen Revolution in der Wissenschaft des zwanzigsten Jahrhunderts: der Quantenmechanik.

28). For the quantum mechanical results that we require we shall be concerned only with stationary states, known sometimes as eigenstates. The wave functions for these states may be referred to as eigenfunctions and the associated energies E as the eigenvalues. The details of the methods of solving the Schro¨dinger equation for c and E for various systems do not concern us here but may be found in books listed in the bibliography. We require only the results, some of which will now be discussed.
1 illustrates one photon of such radiation travelling along the x axis. The electric component of the radiation is in the form of an oscillating electric ﬁeld of strength E and the magnetic component is in the form of an oscillating magnetic ﬁeld of strength H. These oscillating ﬁelds are at right angles to each other, as shown, and, if the directions of the vectors E and H are y and z respectively, then Ey ¼ A sinð2pnt À kxÞ Hz ¼ A sinð2pnt À kxÞ ) ð2:1Þ where A is the amplitude. Therefore, the ﬁelds oscillate sinusoidally with a frequency of 2pn and, because k is the same for each component, they are in-phase.
In the wave picture the circumference 2pr of an orbit of radius r must contain an integral number of wavelengths nl ¼ 2pr ð1:14Þ where n ¼ 1; 2; 3; . . ; 1, for a standing wave to be set up. 3(b) shows how a travelling wave results when n is not an integer: the wave interferes with itself and is destroyed. The picture of the electron in an orbit as a standing wave does, however, pose the important question of where the electron, regarded as a particle, is. We shall consider the answer to this for the case of an electron travelling with constant velocity in a direction x.
