May 2022: This time there is a triple pack... – 3 new online geology programs:
A quiz ... with questions about Germany and german grammar (February 2019)
German teaching material
Minetosh online offers multi-media files for learning german. These include grammar exercises and tests, texts and audio-files for simultaneous listening and reading and video- and audio-files dealing with certain topics of german grammar. For example the “Wechselpräpositionen”. Do have an idea of what this is? Well, “Wechselpräpositionen” are prepositions that change their case with the context in which they are used. Here you can find out, what “Wechselpräpositionen” are and how to use them correctly. So have a look to refresh your German or to learn something new.
Additionally, there's a series of videos (screen-casts) with important german phrases and sentences. With these you may practice some important phrases which might come in handy during a stay inGermany. This may help you to ask for a room in a german “Gasthaus”. Or, when you're sitting in beer-garden and you'd like to order a “Bier” and a “Bratwurst” or some “Apfelwein” and “Handkäse mit Musik”. But there are also sentences dealing with a lot of other situations: asking for one's way, in a garage, at the doctor, etc ... There is a total of 20 volumes with over 400 phrases available.
You may also download all of these items for free. There are interactive files for LibreOffice / OpenOffice or MS Excel allowing to do the exercises without an Internet connection.

Just one request: Please do respect the respective licenses (Creative Commons)!
On the subject of geology, there are web-apps on Minetosh online, LibreOffice Calc worksheets for download (macro-controlled evaluation of microprobe data, calculation of mineral compositions, automatic creation of classification diagrams, CIPW standard, etc. But other things can also be found here (dissertation, photos, Links, cartoons, etc.). Just have a look ...
Below is an overview of the web apps that are already available on Minetosh online:
EcoHouse calculates the specific heating energy consumption of your house or apartment and determines the fuel efficiency class (from A+ to H).
EcoCar calculates the average fuel consumption (Gasoline – Petrol, Diesel, LPG) of your car (in litres per 100 kilometres, miles per US-gallon and miles per imperial (UK) gallon). At the same time the CO2-emissions are determined. Data can be stored locally in the browser.
ToolBox is an extended unit converter which does a lot more than converting units. ToolBox converts, besides the usual units, sexagesimal angles, solid angles, number systems, units of radioactivity, consumption, concentration and cable dimensions. Furthermore, ToolBox calculates spherical surface areas and voltage drop in electrical wires. New in version 1.1: Suspension geometry: Conversion of mm and degrees for track setting.
Geo-1 calculates width of outcrop, true and apparent thickness, as well as true and apparent dip of geological units using various parameters. Data may be saved locally within the browser. Explanations of geological terms are included within the app.
RockClass is used to calculate the CIPW standard from geochemical analyzes of igneous rocks and allows rock classification using the Streckeisen (QAPF) and TAS (total alkali vs. silica) diagrams. The results of the calculations and the diagrams can be easily downloaded as csv and png files.
A simple plagioclase-garnet barometer
This simple program serves for estimating metamorphic pressure with the help of geochemical (microprobe) analyzes of rocks.
The Aluminium-in-Hornblende barometer of Johnson & Rutherford
According to Johnson & Rutherford, metamorphic pressures can be estimated using the aluminum content in hornblendes.
The Amphibole-Plagioclase Thermometer of Holland & Blundy
This program calculates trivalent iron, the occupations/activities in amphiboles, pressure according to Johnson & Rutherford and temperature using the hornblende plagioclase thermometer of Holland & Blundy.
