&lt;blockquote&gt;
&lt;p&gt;…&lt;span&gt;Not only do smart people ask questions when they don’t understand something, but they also ask questions when the world thinks it understands something. Smart people challenge the very limit of human understanding, and push the envelope of what’s possible farther than many people would argue it’s meant to be pushed. Smart people don’t take claims at face value, and smart people don’t rest until they find an explanation they’re comfortable accepting and understanding.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Smart people challenge everything. (You know who taught me that? A smart person.)…&lt;/p&gt;

Because the bigger a pie gets, the more the crust becomes overwhelmed by the filling. It’s simple math. Instructables member turkey tek solved that problem by using the fractal shape of the Koch snowflake. At this size, the pie had to be baked in a custom-made outdoor oven. The &lt;/span&gt;&lt;span&gt;cake &lt;/span&gt;&lt;span&gt;pie is 50 inches in diameter at its widest point, but could have been bigger if the materials for the cooking process were more readily available. Yes, I will have a slice, thank you very much.&lt;/span&gt;&lt;/p&gt;
