&gt; Try taking apart a modern cellphone or a laptop computer. 
&gt; Assuming you can even figure out how to pry it open, the 
&gt; inside is as mysterious and inscrutable as the outside.<p>I remember taking apart old radios as a child in the 70s, marvelling at the colourful transistors and resistors. But I had no way of knowing what exactly these were, and even less of a clue as to how it all worked. So sure, it&#x27;s hard to intuit how a smartphone or a computer works just by looking at the insides. But today&#x27;s budding scientists have the world&#x27;s knowledge at their fingertips, and will be able to find diagrams and schematics for a lot of devices, and a large number of sites explaining what every component is and how it works. You don&#x27;t raise scientists, you give them interesting toys to play with, and they simply raise themselves.
