Argument Johann Heinrich Lambert (1728–1777) developed a very detailed theory of science and experiment. Using Lambert's hygrometric studies, this article provides an introduction to Lambert's theory and its practice. Of special interest is his well-founded theory on the emergence and definition of concepts and his neat eye for heuristics that should ultimately lead to a mathematization of physical phenomena. His use of visualizations in this context is especially remarkable. 

Conducting Observations and Tests: Lambert’s Theory of Empirical Science

Lambert’s conception of empirical knowledge that is part of scientific learning is analyzed to introduce some important theoretical tools in his theory of experience, in particular about the search for the conditions of observations and experimentations as well as the establishment of hypothesis.

Coupling analysis and control of temperature and relative humidity in a drying room

This paper analyzes the coupling influence of temperature and relative humidity in a meat-drying room, and its resulting excessive energy consumption, and shows to require a practical control system that decouples the two factors.



Presentation of J.H. Lambert's text "Vorstellung der Großen durch Figuren" with two analyses of Lambert's practice of visual strategies in his experimental studies.

Lambert's text "Vorstellung der Grosen durch Figuren" is presented that contains his most detailed discussion on the usability of graphs in (experimental) science and is put into the broader context of Lambert's philosophical and mathematical work.

J.H. Lambert's work on probability

SummaryJohann Heinrich Lambert (1728–1777) worked in different spheres of mathematics and its applications, including optics, map projections, and geodesy, and also in astronomy. In the theory of

The relationship between concept and instrument design in eighteenth-century experimental science

Summary The empiricism of eighteenth-century experimental science meant that the development of scientific instruments influenced the formulation of new concepts; a two-way process for new theory

Inventing Temperature: Measurement and Scientific Progress

In Inventing Temperature, Chang takes a historical and philosophical approach to examine how scientists were able to use scientific method to test the reliability of thermometers and how they came to measure the reliability and accuracy of these instruments without a circular reliance on the instruments themselves.

A History of Factor Tables with Notes on the Birth of Number Theory 1657–1817

The history of the construction, organisation and publication of factor tables from 1660 to 1817, in itself a fascinating story, also touches upon many topics of general interest for the history of

The use of graphs is not so much a necessary part of scientific procedure as an extremely useful one, and one that is often taken very much for granted.

An Essay concerning Human Understanding

IT is possible to appreciate the reason for this abridged edition of Locke's great Essay and at the same time to regret its appearance. If it had to be done, no living philosopher is so qualified to
