Timon, known as Klengan, has been thinking about registering as a stem cell donor for some time. In this episode "Mund Auf" he meets Henri, who talks about his own experiences as a stem cell donor. Henri saved the life of a woman from Germany at the age of 18. Without hocus-pocus, but only with his
"Romeo and Juliet", "Hamlet", "Othello" – the list of Shakespeare's masterpieces is very long. The world-famous artist is considered as one of the greatest writers and playwrights of all times. This simpleshow explains the basic facts about the "Bard" and how he influenced the English language as we
In the mid-19th century, chemical assistant Henry Perkin was looking for an synthetic substitute for an antimalarial drug. But instead of quinine, he produces the first synthetic dye: mauveine. An accidental product! Authors: ZDF/Terra X/T. Schrader/J. Koester/F. Steinhardt/Moods in Pictures/Maximi
Power laws simply explained - power, base, exponents - same base - analysis. A power consists of a base and an exponent, the exponent is often written as a superscript. The power laws help you calculate. You either keep the base or the exponent. There is also a case where a power is put in brackets.
Mesomerism simply explained - definition, rules & examples benzene & aniline - organic chemistry. Mesomerism is also called resonance, it describes the bonds in molecules with the help of several structural formulas. The possible structural formulas are the resonance structures. The more resonance s
Isomerism simply explained - definition & types - constitutional isomerism, stereoisomerism, conformational isomerism and configurational isomerism - organic chemistry. Isomerism describes several compounds that have the same molecular formula and molecular mass. Isomerism is distinguished between c
Power functions simply explained graphically - positive/negative odd/even exponents & examples. The equation of a power function is f(x)=ax^n. a is the prefactor, n is an exponent. x^2 or x^4 are functions with positive even exponents, x^3 or x^5 are functions with positive odd exponents. x^-2 or x^
Research published in the New England Journal of Medicine shows an association between the average amount of chocolate each person in country eats, and the number of Nobel Prize winners that country produces. But as the author points out, an association doesn't necessarily mean that eating chocolate
Skeletal structure - representation of organic compounds simply explained - substances and particles - organic chemistry. The skeletal structure represents organic compounds more clearly, simply and faster. In this context, important basic terms are line-angle formula or structural formula and valen
Recent research suggests that some exposure early on to peanut products might be helpful in reducing the risks of later peanut allergies. If you're allergic to peanuts, or have a child that's allergic, you'll know how serious a condition it is. For years, parents have been advised to keep infants
Reactions - basics, charge, electrophiles, nucleophiles explained simply - organic chemistry. In reactions, you consider which molecules are to react with each other. If there is a positively charged atom or a positive charge, there is an electron deficiency. The deficiency can be balanced by an ele
