Q-&-A: Please send in your tricky questions…

Parents flummoxed by their kids impossible-to-answer questions can breathe a sigh of relief. Q-files is coming to the rescue. We so often hear of parents, and sometimes even teachers, confounded by children’s weird and wonderful questions. In an age where general knowledge seems to be on the wane the last thing we want to do is discourage such curiosity. So we have created the Q-&-A feature to offer a helping hand.

We will provide answers to tricky questions on a wide range of subjects including science, nature, history and geography via our new Q-&-A feature. Everyone is invited to submit questions via the contact us page, or by emailing Our experts will select the most interesting questions and publish answers on the site. These will form a permanent part of the encyclopedia.

We kicked off the feature with the first two questions “Why is the sea salty?” and “Why do we cry when we feel sad?” and have plenty more to follow.
