Sacrificial Metals

...simple oxide Fe2O3 but is a compound that actually contains water molecules. It can be represented by Fe2O3.nH2O where n can vary according to the conditions under which the rust forms. The water molecules are incorporated into spaces within the crystal structure of iron oxide. Iron (and steel) is not weather-resistant yet it does find widespread use because of its...

A new mission to the icy moons of Jupiter

...simple organic compounds on Enceladus. Starting with them, I’m trying to understand what more complex compounds might be created in the temperature and pressure conditions of the ocean floor of Enceladus. Specifically, I’m trying to understand if you could synthesise the kind of complex organic chemicals that life needs, such as sugars and amino acids. Grace: My focus...

...simple additions or subtractions. The lowest tier of de Prony’s scheme were eighty relatively unskilled workers who actually produced the mathematical tables. So long as they followed the list of additions and subtractions in the correct order (and got the right result), they would arrive at the right result. Babbage saw de Prony’s monumental tables and made the next...

...simple analysis that most people do, but we looked at how they might’ve been responding to temperatures throughout the current spring plus the whole year-and-half before. And once you do that you find that, alright, three-quarters of species only respond to spring temperature, they respond by advancing their flowering, that’s what we see, that’s what has been...

Superqueeroes: Gender and superheroes

...simple distinctions somewhat. For example, The Dark Knight version of Batman is less clear cut, and the two groups of X-men can be seen as more about assimilationism v radical approaches to activism.
