Speaking of dilutions… Now, I’m not about to go into a huge amount of detail about the history and reasoning behind homeopathy because, firstly, other people havealready done an excellent job of that, secondly I always worry that it starts to sound alarmingly plausible if you’re not ver...
Recap - The Structure of the Atom There are many different models used to describe the structure of an atom. In this model the electrons are shown orbiting around a central nucleus. However, electrons also possess properties typical of waves. The Structure of the Atom There are many different ...
Absurd alkaline ideas – history, horror and jail time (2017) Continuing the theme of health, I’ve written several posts about so-called ‘alkaline’ diets, and this isn’t the most popular (that would be Amazing Alkaline Lemons?) but this is the one I wish more people would read. It...

This chemistry might be highly relevant to the Late Heavy Bombardment period of Earth's history about 4–3.85 billion years ago. In addition, we present an in-depth theoretical analysis of the most challenging step of the reaction pathway, i.e., the TiO2-catalyzed dimerization of formaldehyde ...
The first thing I have learned is that physics, chemistry and biology are not three separate subjects. They overlap a lot, in a way that the arts subjects I did for A-level (French, history, English) in the 1960s never did. For example, atoms initially seem to be the building block ...
