# And Now, Flying Pizza

November 22, 2016

First, people made pizza in their kitchens, rolling out dough and sprinkling the sauce and cheese. Then came pizzerias, where someone else made your pizza for you. Then came pizza delivery, where you could just sit on your couch until your pizza showed up. And now, pizza can fly through the sky to your door. In New Zealand, Domino’s did the world’s first delivery of pizza by drone. Drones are small flying objects with lots of spinning propellers. You fly drones using remote control, steering them over and around trees, cars and people. That’s a speedy way for a pizza to travel from the pizzeria to your home. We all get to eat a lot sooner!

Wee ones: Pizzas can be circles or rectangles. Look for 1 of each shape in your room. Which did you find first?

Little kids: If you’ve eaten 4 slices of pizza, what numbers are the next 2 slices you eat?  Bonus: If you cut 1 pizza into 8 equal slices and another same-size pizza into 6 equal slices, which one has the bigger slices?

Big kids: If pizzas weigh 2 pounds each, how much weight does a drone have to carry to deliver 11 pizzas at once?  Bonus: If it takes a car 15 minutes to bring you pizza, but a drone takes only 1/3 as long, how many minutes does the drone save?

The sky’s the limit, even for pizza: If on the way to your home the drone has to fly up, then left, then down, then right, then up again to repeat the pattern, how many times does it turn left in its 150 moves to reach you?

Wee ones: Different for everyone…circles might include a clock, a plate or a button; rectangles might include a door or window frame, a book, or the side of a box.

Little kids: Slices 5 and 6.  Bonus: The one cut into 6 slices has bigger slices, because the same amount of pizza gets split up among fewer pieces.

Big kids: 22 pounds.  Bonus: 10 minutes out of the 15, since the drone takes only 5 minutes.

The sky’s the limit: 38 left turns. 148 is the biggest multiple of 4 less than 150, and includes 37 full sets, including 37 left turns. Then it starts the pattern again, and goes up on the 149th move, then left on the 150th. So we add 1 more left turn.

Her mom had Laura baking while still in diapers, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
