Alice In Wonderland

Down the Rabbit-Hole

Alice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, “and what is the use of a book,” thought Alice “without pictures or conversations?”

So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.

There was nothing so very remarkable in that; nor did Alice think it so very much out of the way to hear the Rabbit say to itself, “Oh dear! Oh dear! I shall be late!” (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.

When the battle's lost and won.

Pizza Volume

The Script

Would you like fries with that?

We offer two-dozen varieties of fast food, of which there are 9 types of pizza, but if you want to design your own, the number of combinations possible using 12 ingredients is 12*11*10*9*8*7*6*5*4*3*2 = a very big number!

Please tell me your phone number in case we have changed your mind.

Would you like to order the very same thing this time next week? I’ll give you a secret code.

Thank you, come again!

Design Thinking

FAST THINKING (System 1) enables us to get through the day by handling routine decisions with less mental effort. It is mostly unconscious & instinctive.

SLOW THINKING (System 2) works the brain more. It is infrequent, logical & calculating, and requires deliberate, focused attention.

STOP THINKING (System 3) nigh impossible.
