With the help of the standard hydrogen half-cell, the potentials of all other half-cells can be determined. The standard hydrogen half-cell represents the defined 0-point. Therefore, these measured potentials are referred to as standard potentials. Original: "Wolfgang Dukorn" Original: German. All
In this video we are going to look at how to do calculations with standard form. When adding and subtracting numbers in standard form, we need to write the numbers out into ordinary numbers, do the sum and then turn the answer back into standard form. With multiplication and division we can work
The concentration dependence of the redox potential is explained and Nernst's equation is derived from it. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
With the measurements of all half-cells against the standard hydrogen half-cell, the voltage series can be established. This screencast explains how to deal with this table and what statements can be read from it. Original: "Wolfgang Dukorn" Original: German. All translations in this video have be
Limit values are there to protect us – but who actually sets them? And who can change it again? Politics and science work hand in hand here. We show how it works in the video. Original: "Federal Office for Radiation Protection" Original: German. All translations in this video have been done by the
5G is the upcoming standard in mobile communication. What do we know about the health effects? Original: "Federal Office for Radiation Protection" Original: German. All translations in this video have been done by the alugha AI.
Around 1,700 probes measure environmental radioactivity in Germany around the clock – and all of them have to be maintained regularly. In a new video from the series "50 Years of the Radioactivity Measurement Network", we show you what is in the probes and what tests they have to undergo again and a
Are you considering pursuing a master's degree but wondering which ones are the most competitive? In this video, Dickson Wong, our award winning tutor for Maths, Economics, and Mandarin dives into the toughest master's degrees to get into. Find out what makes these programs so selective, and get tip
Moral disengagement is a process of cognitive restructuring that allows individuals to distance themselves from their inner moral standards and act unethically without feeling uncomfortable doing so. It's the story we tell ourselves so as not to feel bad about inhumane acts that would normally viola

In this video, HANS-MARTIN VON GAUDECKER considers how the crisis is affecting human inequality. Is the pand
The competencies and levels in the framework curriculum for sports for Berlin-Brandenburg are presented in detail and vividly. The principles can be transferred to the framework curricula of other federal states. Original: "Sports didactics simply explained" (Humboldt University of Berlin, Departm
What make advanced materials potentially harmful? In part 5 of this Risk Bites series on advanced materials, we explore what characteristics of materials affect their safety, and increase their potential risks to human health. Risk Bites was created by Andrew Maynard. This week's video was prod
