Nanotechnology for Wizards

Wizard HatNow if Harry Potter is really a figment of the imagination then why would someone take the trouble to write to the Ministry of Magic?  I found this article on the Nanotechnology Now website.  Andrew Maynard, Chief Science Advisor, Project on Emerging Nanotechnologies has written a letter to Arthur Weasley of the Ministry of Magic to enquire what they might make of our more advanced technologies, such as nanotechnology. 

The muggles of this world look forward to seeing how Mr Weasley responds!
