Charlies Vater hatte immer davon geträumt, Fußballprofi zu werden, und als sein begabter Sohn im Alter von 14 Jahren das Angebot bekommt, in der Jugendmannschaft eines Proficlubs zu spielen, ist er mehr als stolz. Doch Charlie hat ein Geheimnis: Er ist eigentlich ein Mädchen, das im falschen Körper steckt.
Greta Schiller und Andrea Weiss zeichnen die Geschichte des Sichtbarwerdens von Schwulen und Lesben in der amerikanischen Gesellschaft auf - ein lebendiges Dokument mit Filmausschnitten und Anekdoten einer verborgenen Geschichte, voller Witz und Ironie und manchmal auch Traurigkeit.
Etwa 100.000 Homosexuelle sind während der NS-Herrschaft in Deutschland inhaftiert und gefoltert worden. Zu Tausenden wurden Schwule und Lesben in deutschen KZ ermordet. Rob Epstein und Jeffrey Friedman zeichnen das Schicksal der Homosexuellen im Dritten Reich nach.
Our muscles work miracles. We can run long distances and perform complex coordinative movements. Our muscles need energy to do so. Adenosine triphosphate, ATP for short, is essential in the provision of energy to muscles. Because without ATP, muscles cannot contract. This film explains how the ATP gets to and feeds the muscles.
Twenty-four hours fit into a day, 60 minutes into an hour - time is a little more complicated to learn than other units of measurement with their simple tenths and hundredths. This video uses vivid animations to explain how to read the clock. The viewer also learns how and why people began to measure time.
The subject of this film is the graphical representation of percentage calculations. The principle of visualizing parts and their proportions in histograms or pie charts is explained. The various criteria that have to be taken into account to reach a reliable and accurate graphical representation are looked at.

The subject of this film is improper fractions. In top-heavy fractions the numerator is a multiple of the denominator. Top-heavy fractions can therefore be converted into whole numbers using reduction. The film uses clear examples to explain what top-heavy fractions are and how to calculate with them.
We are familiar with the term growth from everyday life. Children grow, the state´s mountain of debt grows, the number of computer users worldwide too. Generally we can say: if any size increases with time, we refer to growth. This film explains the term growth in detail, including positive and negative growth.
In logistic growth, exponential and bounded growth are combined. The curve of a logistic growth starts exponential. In the middle it becomes approximately linear, and it finally ends at a limit which cannot be exceeded. The video explains the formula and gives some illustrative examples from everyday life.
Limited growth is characterized by the fact that it does not exceed a certain limit or bound. The film explains limited growth using several catchy examples from the economy, nature and everyday life, explains the recursive function equation and finally illustrates limited growth with an exponential function.
The audience learns what exponential growth is through the legend of Buddhiram, the inventor of chess. The video explains the recursive and explicit functional equations and shows how both positive and negative exponential growth work. Exponential, linear and quadratic growth are compared with each other.
Using examples from everyday life as well as animations and real models, we show you how the surfaces of different geometric figures can be understood using grids. Clear examples of the grids of tetrahedrons, square pyramids, cuboids, and prisms as well as complicated shapes such as cylinders and cones are shown.
The film explains how the fraction bar, the numerator, and the denominator work: The denominator gives the fraction its name, while the numerator gives the number of parts. It is shown that fractions with the same name can easily be added. The fraction calculation is illustrated with everyday examples.
This film introduces the construction and the daily use of circles. Easy-to-understand practical examples show how circles can be made with the help of a compass or using string, and how important these geometric shapes are in navigation and shipping. The uses of the circle in art are also mentioned in this film.
When adding or reducing fractions, it is helpful to know the least common multiple and the greatest common divisor. The video shows how to find these numbers using several illustrative examples. Both denominators or both denominators and numerators must be reduced with the help of the prime factorization.
The basics of interest calculation are presented using practical examples. Credit, capital, interest rate and term are explained. Clear calculation examples explain how the interest rate affects the amount of money that has to be paid back. The different terms of loans and per annum interest are also introduced.
For comparison and calculation, fractions can be expanded until they have the same denominator. To do this, the numerator and denominator are multiplied by the same number, whereby the valence does not change. If the numerator and denominator have a common divisor, you can reduce the fraction by this number.
Fractions can easily be divided by multiplying the first fraction by the reciprocal of the second fraction. The film shows the individual steps necessary for this with the help of an illustrative example and explains the rules that apply here. The reduction advantage for mental arithmeticians is also discussed.
You can expand decimal numbers in the same way as fractions in order to be able to calculate with them more easily. The film explains how the same-sense comma shift works. In addition, the viewers learn how they can easily convert any fractions into decimal numbers with the help of written division.
This film is about which numbers are divisible by which other numbers. The video explains the divisibility rules and how to check them: Depending on whether a remainder is left after division or not, a number is divisible by another number. Illustrative examples explain the rules of the last digit and the checksum.
Using three examples, this film explains how the distances of different points in the Cartesian coordinate system are determined. It explains which formulas have to be used and which rules apply. The distance between a point and the origin is worked out and applied to the calculation of the distance between two points.
This film´s topic is the decimal system. The basic principles of counting and writing numbers in different cultures are described. It is thanks to an Arabic mathematician that the decimal system and the written basic arithmetic methods ever spread as far as Europe and that we nowadays call these numbers "Arabic numerals".
This film uses an example from everyday school life to demonstrate the intercept theorems when scaling a triangle centrally. The first and second intercept theorems are explained and shown in detail using specific problems. The benefit in daily life is then also shown when calculating a difficult to measure length.
Three laws of arithmetic - the commutative law, the distributive law and the associative law - make arithmetic easier. The film introduces the three laws, explains their meaning and gives the corresponding formulae. The content of each law is summarized in an understandable way in a short and catchy mnemonic.
The subject of this film is linear equations. Equations are made up of a series of mathematical symbols with logical connections that are linked by an equals sign. An equation is always linear if the variables do not occur in any power higher than the 1st. Linear equations are solved using equivalence transformations.
There are five Platonic solids in mathematics. They were named after their discoverer, Plato. The video introduces the hexahedron, the tetrahedron, the octahedron, the icosahedron, and the dodecahedron with their respective symmetrical peculiarities. It explains where these regular shapes occur in nature.
This film first gives several examples of reflections in the Cartesian coordinate system and then develops generally applicable rules from them. First, individual points are mirrored on the y-axis, the x-axis and the zero point. Then it is shown that and why mirroring also works with geometric figures.
This video looks at the basics of probability calculation. First of all, the term probability is explained. Using ideal random trials, disjoint and non-dijoint events are defined amongst others, simple probabilities for disjoint events are calculated, and the respective arithmetic rules are presented.
Prime numbers are only divisible by themselves and by one. All other numbers consist of products of prime numbers. In the video, examples are used to show how a number can be identified as a prime number, both through the application of divisibility rules and through the helpful sieve of Eratosthenes.
