Measurement technologies are getting increasingly sensitive -- but what does it mean for risk when we can measure the smallest amount of a substance in the stuff we eat, drink and breathe? Note: In talking about the hypothetical risk from the hypothetical substance Greensave, the video talks abou
What are the ethical issues that emerge as our ability to detect chemicals in the environment around us improves? This week's risk bites looks at the ethical dimension of the measurement conundrum -- when our ability to detect stuff outstrips our understanding of what to do with the information. Th
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
Learn the basics about Measures of electricity. What techniques and methods are used to measure electricity? Find out more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind The Fuse School. These videos
Our stationary probes measure the local dose rate at a specific location around the clock. So we always know how much it is radiating at that place. But in order to determine what is radiating there - i.e. which substances - we need a different kind of measurement. We carry them out at regular inter
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
Explore how astronomers and scientists use astronomical units to measure distances in the solar system in this video adapted from NASA. The astronomical unit (au) -- equal to the average distance from Earth to the Sun -- is a convenient unit of measure when talking about distances in the solar syste
1,700 probes are distributed throughout Germany and permanently monitor the #Umweltradioaktivität. In this video we show you where the probes are, what the measurement results depend on and what can happen in the life of a probe ... You can see the exact measurement results here: https://odlinfo.bf
Avalanche Safety is essential for survival while you’re in the mountains in winter. This video briefly explains how to behave and react in case of an avalanche accident while skiing or snowboarding. Click here to see more videos: https://alugha.com/mysimpleshow Authors: Nikolaus Kramheller, Lisa-
Learn how to prepare Avalanche Safety! This video briefly explains what factors to take into consideration when preparing for a skiing or snowboarding trip in areas exposed to avalanches. Click here to see more videos: https://alugha.com/mysimpleshow Authors: Nikolaus Kramheller, Lisa-Marie Grimme
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
How do you go about avoiding becoming infected by a harmful airborne virus like COVID-19 -- especially if you're a student heading back to campus? There are, of course, a number of blindingly obvious ways to do this. However, because so many people seem to have forgotten them, I thought it worth p
