Quasicrystals: What do we know? What do we want to know? What can we know?

More than 35 years and 11 000 publications after the discovery of quasicrystals by Dan Shechtman, quite a bit is known about their occurrence, formation, stability, structures and physical properties. It has also been discovered that quasiperiodic self-assembly is not restricted to intermetallics, but can take place in systems on the meso- and macroscales. However, there are some blank areas, e...

Cryptochromes--a potential magnetoreceptor: what do we know and what do we want to know?

Cryptochromes have been suggested to be the primary magnetoreceptor molecules underlying light-dependent magnetic compass detection in migratory birds. Here we review and evaluate (i) what is known about these candidate magnetoreceptor molecules, (ii) what characteristics cryptochrome molecules must fulfil to possibly underlie light-dependent, radical pair based magnetoreception, (iii) what evi...

Why Don’t They Do What We Want Them to Do?

This paper describes an investigation into the factors affecting a student’s decision whether to construct a state transition diagram in order to verify the correctness of a concurrent program, or whether to verbally verify the program. We conjectured that the advantages of the visual formal tool would cause it to be adopted as a routine part of the students’ practice, but in fact the verbal de...

Diagnostic and therapeutic challenges for dermatologists: What shall we do when we don’t know what to do?

What shall we do when we have done everything we could for the diagnosis and treatment of a patient, but were not successful? What shall we do when there is no definite treatment for a patient? What shall we do when we have no diagnosis or treatment for a patient? Some useful suggestions are presented here to get rid of these situations.
