     31    <p>Measurement- and Experimental technology can link Communication and Computer
     32       Technology. Measurement technology has a long history and there have been nice and
     33       remarkable devices.</p>
     34<!--
    3135    <p>Professionals can see many beautiful measurement devices, from the complex mirror galvanometer (a piece from the German Kaiserzeit) to the scintillation measuring station with counting devices from several epoches (since 1956), used for measurement of radioactivity.</p>

     41           This picture shows some devices from the "experimental physics" area. You
     42           will probably note the use of "natural" materials (wood, glass, metal) and the
     43           well-designed very simplified interface that makes comprehension simple.
     44           <br/>We will go into detail for some of the devices shown on the left.

     65           <div class="bildtext">
     66             <p>Until the invention of measurement amplifiers, measuring very small voltages
     67             and currents was a big problem. To do that job, moving coil devices had to be
     68             very sensitive. This was realized with a moving coil that was mounted on a
     69             torsion wire. The reflecting mirror at the lower end of the wire was spotted by
     70             a light ray, so the whole composition acts like a very long "light needle".
     71             By this way very long needle lengths (multiple meters) could be simulated.
     72             Such a galvanometer must be set up absolutely horizontally and vibration-free.
     73             <br/>The <b>Mirror Galvanometer</b> by Hartmann&nbsp;&nbsp;&nbsp;Braun is
     74             a simple and functional demonstration model from the 1920s.</p>

     81        <p class="bildtext">
     82            At the time where there was no television and no oscilloscope yet, the
     83            <b>Cathode Ray Tube</b> was a sensation, especially at school. This was one of
     84            the very first experiments where students could see that electrons have
     85            almost no inertia, so they can be deflected easily at the presence of an
     86            electric field.
     87            <br/>This tube (with power supply on the left) from the German company
     88            <b>Loewe</b> is an historical piece from the 1930s. It measures about
     89            50&nbsp;cm!

    64       <p>In addition to the measurement technology that mostly covers the big area of counting, there are also exhibits which show how electronics was taught in schools since 1930. The picture stated below shows at the top demo models for tube technology (approx. 1935) and galvanometers, demo tubes (approx. 1939) and an oscillating circuit (variometer) under it.</p>

     113          <p class="bildtext">
     114             The "Physikalischen Werkst&auml;tten" (<i>phsyical facilities</i>), <b>Phywe</b>,
     115             have built this small oscilloscope for demonstration purposes that can be
     116             used to show the electromagnetic interaction of an electron beam in E/B fields.
     117             Since (CRT driven) television got a mass medium, these experiments
     118             were state-of-art at those days.

    66     <p>On the third shelf (counted from the top, in the background) the
    67        picture shows models of transistorized circuits (from
    68        approximately 1965). The big white board in front of these models
    69        is an experience system from Leybold from the early 1970. At that
    70        time, the subject "digital electonics" was taught in the school.
    71        It was a wonderful combination of physics, informatics and
    72        mathematics.  Unfortunately that time is over, too. In ordinary
    73        schools, there is no more time for electronics in the curriculars.
    74        Of course that is not totally wrong: The every day electonics have
    75        developed too much away from the basis. Thus, the youngest
    76        generation has no more idea how it's Ipod or mobile phone works
    77        and they do not even want to learn the basics of electronics
    78        because the relationship is too complex.</p>

     136          <b>Leybold</b> from the early 1970s. At that time, the subject

     138          logic systems like binary counters, full adders, flip-flops, multiplexer,
     139          etc. This was quite fascinating for students at that time. Today, in ordinary

     149         electron tubes) or discrete transistor logic (mostly germanium).
     150         The different counting tubes (e.g. E1T or GC10B) and the very different

     52    <!-- <LOL> -->
     53    <br/>In the year 1959 some BULL engineer asked himself why there was not some
     54       algorithm for the tabulating machine somewhere outside to compute square roots.
     55       Since he was bored, he knew already dozens of simple algorithms he learned
     56       in his study of computer science and he wanted to gouge his friends, he
     57       bet them that you could compute square roots of any real number with a
     58       tabulating machine. Since his friends have not studied computer science,
     59       they bet against it. The engineer made some programming efforts and won
     60       the bet. We came across that program, so we are currently trying to get
     61       it back running, so we can relive that historical moment. <!-- </LOL> -->
