The polarimeter is an important measuring instrument for determining the specific angle of rotation of an optically active substance. This first video is exclusively about the construction of a polarimeter. Afterwards, a short measurement is also carried out. Only in another video will I explain how
This second video about the polarimeter is all about how it works. In particular, the polarization foils, polarization and analyzer are named, considered and described. Furthermore, it is discussed how the oscillation plane of linearly polarized light changes. Original: "Wolfgang Dukorn" Original:
The structure of the amino acid molecules is discussed. Due to the different remains, there are 20 naturally occurring AS. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Airplane safety starts with the construction of aircrafts. Every defect that could occur is already taken into account during construction. All safety-relevant systems or components are available at least twice. Author: ZDF/3sat/nano/docuvista/A. Leuschner/M. Wurtscheid/H. Müller/S.Reeh/Maximilian
The Roman Empire benefited from an extensive road network. Transport routes emerged throughout the empire. Especially the many legionaries from the individual provinces had to serve as construction workers. Author: ZDF/Terra X/Gruppe 5/ Susanne Utzt, Cristina Trebbi/ Jens Boeck, Dieter Stürmer / Fa

Climate-damaging LNG production in Canada by means of German financial guarantees Germany has now finally decided to phase out coal for 2038 - much too late, as climate activists criticise. At the same time, however, it is this delayed and inadequate coal phase-out that is being used as an opportu
Learn how gravity can be described as the curving of spacetime, according to Einstein’s general theory of relativity, in this video from NOVA: Black Hole Apocalypse. Computer animations illustrate the concept of warped spacetime and how objects “fall” along a curved path. Use this resource to visual
The spatial structure of the most important molecules is explained and then practiced. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Learn how drip irrigation helps conserve water as compared with traditional irrigation methods in this video from the California Academy of Sciences. This resource stimulates students’ thinking about protecting this limited resource. Students can ask questions, develop a model, and make evidence-bas
