Father: “Now you can explain to your class how prime factorization works.”

Daughter: “No, they already got it. I’m the only one who didn’t understand.”

Father: “I don’t believe that for a second.”

Daughter: “I believe it for a million seconds.”

Father: “Really? How long is a million seconds?”

Daughter: “I don’t know.”

Father: “Let’s find out.”

Daughter: (looking at calculator) “How do you even write a million?”

Father: “One, zero zero zero, zero zero zero. Now how many seconds in a minute?”

Daughter: “Sixty.”

Father: “So divide a million by sixty. Now how many minutes in an hour?”

Daughter: “Sixty again. Now what?”

Father: “How many hours in a day?”

Daughter: “Twenty-four.”

Father: “So divide by twenty-four. What did you get.”

Daughter: “Woah. Eleven point five seven.”

Father: “So eleven and a half days.”

Daughter: “Wow, it seems like it’d be so much more than that. What about a billion? How do you write that?”

Father: “One, zero zero zero, zero zero zero, zero zero zero. So divide that by 60. 60, and 24, just like before.”

Daughter: “Woah.”

Father: “Wait, we’re not done yet. How many days in a year?”

Daughter: “Um . . . 365?”

Father: “Right, so divide that number by 365. What did you get?

Daughter: “Thirty-one?”

Father: “Thirty-one what?”

Daughter: “Days? No, years!”

Father: “Right!”

Daughter: “Wow. A billion seconds is 31 years, but a million seconds is only 11 days! Mind – pssssh – blown!”

Is there anything better than watching a child get excited about an idea?
