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
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
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

After over 210 years of unification, the United Kingdom is looking shaky. An independence referendum in 2014 saw Scots questioning whether or not to decapitate a kingdom, and the Brexit vote of 2016 began unpicking the seams of an already worn stitch between the four unified countries. As politics r
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
