3.3-year-old Stuart has started asking some challenging questions. They are not only difficult to explain to someone at his level in general, but also requires us to study some to brush up on the respective areas.

Some examples:

“What’s the biggest number?” “Infinity? What’s that?” “If not 100, then 101? 1 million?” “Or is it just ‘many’?”
“Why does wood burn?”
“How does melted plastic stick to another piece?”
