Scientific observation is determined by the human sensory system, which generally relies on instruments that serve as mediators between the world and the senses. Instruments came in the shape of Heron's Dioptra, Levi Ben Gerson's Cross-staff, Egnatio Danti's Torqvetto Astronomico, Tycho's Quadrant, Galileo's Geometric Military Compass, or Kepler's Ecliptic Instrument. At the beginning of the seventeenth century, however, it was unclear how an instrument such as the telescope could be employed… 
Galileo's Knowledge of Optics and the Functioning of the Telescope ─ Revised
What are the historical evidence concerning the turning of the spyglass into an astronomical instrument—the telescope? In Sidereus Nuncius and in his private correspondence Galileo tells the reader
Magnification: how to turn a spyglass into an astronomical telescope
According to the received view, the first spyglass was assembled without any theory of how the instrument magnifies. Galileo, who was the first to use the device as a scientific instrument, improved
Instruments in science and technology
Modern science and technology are interwoven into a complex that is sometimes called 'techno-science': the progress of science is dependent on the sophistication of instrumentation, whereas the
The origins of the telescope
The origins of the telescope have been debated since the instrument’s appearance in the Hague in 1608. Civic and national pride has led local dignitaries, popular writers, and scholars to present

It is argued that computer simulations are best understood as instruments and can better elucidate their actual role as well as their potential epistemic standing in relation to science and other scientific methods, practices and devices.
And, Yet it Moves
Is there anything on which everyone can agree? That’s the trouble with ‘truth.’ Everyone seeks it, and controversy occurs when it’s found. Can there be contradictory truths? If something is believed


New Light on Tycho's Instruments
In 1908J. A. Repso1dsurveyed the bewildering array of two dozen instruments described and depicted by Tycho Brahe in his Astronomiae instauratae mechanica (1598)1 and reached the conclusion that
On Kepler's awareness of the problem of experimental error
Summary This paper is an account of Kepler's explicit awareness of the problem of experimental error. As a study of the Astronomia nova shows, Kepler exploited his awareness of the occurrences of

Sunspots, Galileo, and the Orbit of the Earth
TOWARD THE END of the sixteenth century, Galileo came to the opinion that the earth was in motion, motion very similar to that proposed by Copernicus some half-century earlier. The problem of
Galileo, Scheiner, and the Interpretation of Sunspots
H ISTORIANS OF SCIENCE ARE AGREED that Galileo must be judged against the background of the science of his day and in the light of questions debated by his contemporaries. Unfortunately, this effort
Going Wrong: To Make a Mistake, to Fall into an Error
Heinrich Hertz, the celebrated German experimenter and theoretician, conducted in 1883 experiments on cathode rays. He concluded these pioneering experiments by stating that "the electrostatic and
Galileo's Proof for the Earth's Motion from the Movement of Sunspots
Toward the middle of the Third Day of his Dialogue Concerning the Two Chief World Systems, Galileo promises to demonstrate the earth's motion from certain appearances connected with the movement of
Astronomical Instruments and Their Users: Tycho Brahe to William Lassell
This volume looks at the way in which the development of a viable instrument technology has lain at the heart of astronomical research since the late-16th century. In particular, the concern with
Galileo Engineer: Art and Modern Science
The Argument In spite of Koyré's conclusions, there are sufficient reasons to claim that Galileo, and with him the beginnings of classical mechanics in early modern times, was closely related to
Sunspots or Sun's Planets: Jean Tarde and the Sunspot Controversy of the Early Seventeenth Century
The seemingly innocuous phenomena known as sunspots generated one of the most bitter disputes of the early Scientific Revolution. The dispute entailed at least three noteworthy aspects: first,
