Looking through a phone

The headline hooked me--turn a cellphone into a microphone. The lede and clear writing sustained me. This article is great.
By the time I reached its end, I found that any question that cropped up while I read, was eventually addressed. The author talks about the inception and construction of the phone-turned-microscope, breaking down technical jargon into lay terms for us to understand how it works, tells of its application and value in day-to-day life, and its possible future--commercialization. By quoting experts in various fields he shows us its extensive applicability and potential.
