Climate change: transitions to sustainability

...carbon taxes be seen as examples of policies based in a ‘non-reciprocal’ sense of justice, or compassion? These policies could be seen as reflecting a ‘bedding down’ of non-reciprocal obligations to the future and the non-human natural world. We are bound by these obligations, but this isn't like the deal that was struck when Western European countries set up...

...carbon. While this can sustain a star for a short period of time after the main sequence, it is less efficient than hydrogen fusion. In this process helium nuclei, also known as alpha particles (α-particles), fuse together to form heavier nuclei. What is the overall effect of this triple alpha process? Think about what goes into the reaction and what comes out. Answer...

Understanding antibiotic resistance

...carbon atoms and one nitrogen atom. But even more importantly, note that as a four-membered ring, the bond angle now between the carbons-- instead of being like the tetrahedral carbon bond angle of 109 degrees, it's constrained to be just 90 degrees. That introduces what we call ring strain into the molecule. And it's a way in which molecules are encouraged, therefore, to...
