Today I received an e-mail from an unhappy reader where I am being mercilessly criticized for misleading the visitors to my blog.

Mr. X is rightfully accusing me for not staying focused on the topic of “just chromatography” and that I spend too much time on nanotechnology and things like witricity. What can I say in my defense? Not much, I am guilty. But how can I not write about the exciting discoveries and knowhows such as wireless power transfers, nano light bulbs, or laser induced imploding bubbles?!
