Collection area: Technical and Scientific Principles

The "basic sciences of technology" have formed the foundation of the collections since the museum was founded. The long-term, predominant image of technology as an applied science has since given way to a more complex idea of the origins and applications of technology. Astronomy, physics and chemistry help us to understand the macrocosmic and microcosmic structure of the world.

Geodesy
  • FA-123669

    Autograph Wild A7 photogrammetric stereoplotter

    Many people rely on accurate maps from which the height of the terrain can be read. These can be created using photogrammetric devices such as the A7.

  • FA-123752

    Depth sounder

    The depth of water cannot be measured using tape measures. Instead, a depth sounder is used for this, which uses ultrasound for measuring depth.

  • FA-124203

    Pair of globes

    Where is my holiday destination located? A map can show us this, but a globe does it much nicer. This way of depicting heaven and earth is centuries old.

  • FA-123658

    TODIS base range finder

    The distance of inaccessible points in open territory cannot be ascertained using tape measures. Optical range finders are used instead.



Medical and Biotechnology
  • FA-122387

    Audiometer

    Is your hearing poor or does your interlocutor speaks too quietly? Only a measurement device can provide information on this: the audiometer.

  • FA-123647

    Mingograph 1600 multiple EEG recorder

    Many processes in the human body are related to electrical currents. By use of sensitive devices these can be picked up on the skin surface and recorded. 

  • Whole-body X-ray machine

    Since the discovery of X-rays by Wilhelm Conrad Röntgen in 1895, "transillumination" has become one of the most important diagnostic tools in medicine.



Measurement, Testing and Control Technology
  • FA-104300

    Decorative astronomical clock

    This work of art is much more than a simple clock. This mechanical device simultaneously represents Ptolemy's ancient view of the world.

  • FA-123456

    Light-beam oscilloscope

    Vibrations can only rarely be seen with the naked eye. Converted into an electrical signal, they can be observed using an oscilloscope.

  • Münzwaage mit vier Gewichten in einem Etui

    Set of coin scales with four weights inside a case

    Coin scales were used to check the precious metal content of gold and silver coins. And perhaps Hofrat Theodor Wolf did indeed check coins in his professional capacity as a revenue officer working for the finance authorities. In May 1938 he decided to give the scales to the TMW.



Physical/Chemical Fundamentals
  • 1405_Armillarsphäre_TMW

    Armillarsphäre, um 1850

    Unfortunately this article is only available in German.

  • FA-123588

    DSM 940 electron microscope

    The electron microscope can do what the light-optical microscope doesn’t achieve. This device allows magnifications up to 200,000 times.

  • FA-121724

    Laser vibrometry system

    Acoustic oscillations and vibrations can only rarely be seen with the naked eye. However, they can be made visible using a measuring device and a computer.

  • FA-123653

    Mass spectrometer

    Can you "weigh" atoms? It is not possible by using scales. However, with a mass spectrometer, you can even separate particles of different "weights".

  • FA-103194_Brahe-Sextant

    Sextant

    Sextants are devices for measuring angles. They are used to determine the position of stars and (as small, manual devices) for determining one's position at sea.



Calculating, Drawing & Design Instruments
  • FA-124238

    Demonstration slide rule

    Slide rules are simple calculation aids used for making rough estimates. Large demonstration devices were used for training.

  • FA-123561

    Disk planimeter

    Who wants to measure areas by counting squares on graph paper? The planimeter does this mechanically.

  • FA-123651

    Panel with rulers

    Rulers in all their various forms are indispensable aids in making geometric drawings by hand.
