This week’s Feedback column (that I write) in New Scientist magazine has three segments. Here’s how each of them ends:
- Turning point—… And that paper, in its own turn, led to a study published this year in the journal Scientific Reports. It is called “Influence of roundness errors of bearing components on rotational accuracy of cylindrical roller bearings”. The authors lament that “there is relatively little research on the rotational accuracy of rolling bearings”. For youthful great explorers, keen for adventure, this unmapped territory beckons.
- A Pretty Sweet biting issue—… Four years ago, Pretty also peered into the story, and not a very sweet one, of older people and their teeth. The Pretty team looked at what happens when you ask some older folk the question: “What would you fear happening to your mouth?” The answer, as described in a study in the International Journal of Health Services: plenty.
- Arithmomania—… Maddeningly, for scientists and people with arithmomania, and for those who count themselves as being both, the exact number of causes for the condition could turn out to be uncountable.
