10 Polarization in electrophilic addition
The step of polarization repeatedly causes difficulties in understanding. For this reason, this screencast is intended for classroom follow-up and only illustrates the step of polarization of the bromine molecule by ethylene. Original: "Wolfgang Dukorn" Original: German. All translations in this v
Namibia's national parks
Just under 20% of Namibia's area is made up of state national parks. Now, almost 90 municipal nature reserves have been added. Together with private reserves, a total of about 40 percent of the country is protected. Author: ZDF/Terra X/R.Marel/C.Gerisch/SpiegelTV/Jochen Schmidt Translation and dub
The extermination of Jews under National Socialism
At the Wannsee Conference, Reinhard Heydrich explained the new strategy: the National Socialists no longer want to expel the Jews, but murder them. Extermination camps were created in the East. Author: ZDF/Terra X/L. Schöler/J. Geiß/K. J. Sturm/K. Waldmann/M. Fandel/B. Leng/Margot Friedländer Conte
United Nations Day
United Nations Day, on 24 October, marks the anniversary of the day in 1945 when the United Nations was formed as the UN Charter came into being. Our video raises awareness of this day, celebrated every year, to reaffirm the purposes and principles of the UN Charter. #UN #UnitedNationsDay Transcrip
Solar System Dynamics: Orbits and Kepler's Laws | NASA Planetary Sciences
Explore how human understanding of planetary orbits has changed throughout history in this video about Kepler's laws of planetary motion. Kepler's three laws of planetary motion accurately describe the elliptical orbits of objects around the Sun. This video presents the story of Johannes Kepler and

Power Stations & The National Grid | Electricity | Physics | FuseSchool
The flick of a switch, that’s how easy it is to get electricity, right? If you’re one of the lucky ones, then yes. But in 2017 there are still over 1 billion people who do not have access to electricity. In this video we will discuss how electricity is generated and transferred to our homes, for th
The Polarimeter - How it works
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:
09 Intermolecular Interactions
Van der Waals forces, dipole-dipole interactions and hydrogen bonds are explained. It is briefly repeated again how the polarity of molecules can be determined. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
ScienceCasts: Taking the Wild out of Wildfire
A new NASA-funded tool is taking some of the ‘wild’ out of wildfires by making it possible for U.S. fire managers to better spot dangerous blazes. Visit http://science.nasa.gov/ for more. Active fire maps of the United States: http://activefiremaps.fs.fed.us Click here to see more videos: https:/
Q 11 Mutarotation in glucose
alpha-glucose and beta-glucose are in balance. This can be demonstrated by measuring the angle of rotation of linearly polarized light. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
