## Conversations about the largest number

We're at a restaurant waiting for our food. My 9yo is discussing large numbers.

Sempi: Did you know that googol is 1 followed by 100 zeroes?

Me: Yeah.

Sempi: And googolplex means 1 raised to the power of googol.

Me: Technically it is 10 to the power of googol because 1 to the power of anything is just 1.

Sempi: Ok. (whatever).

Me: Also Google is named after googol.

Sempi: I know.

Sempi: Oooh. Cool!

Vian (6yo): Is that the biggest number in the universe.

Yoshi: I read that there aren't googolplex number of atoms in the universe.

Me: Well technically there is a number that is so unimaginably large. It is called Graham's Number.

Sempi and Vian: Oh. How many zeros does it have? 1000?

Me: No it is so big that you can't even imagine it. (I try reading the wikipedia entry without success)

Me: I can't quite explain it very well because I don't fully understand it myself.

-------------

Next day I'm walking Vian to school. We're doing imaginative "talk play". Vian is describing a generator in Minecraft that can produce something infinitely.

Vian: It just keeps generating it forever. Actually that's not true, it only goes up to that number that you couldn't explain.

Me: Graham's number?

Vian: Yeah, that.

-------------

I'm so proud that Graham's number is a casual quantity in our household now.

## Measure of Age

Vian (5yo) is curious as ever. He asked me how old I am.

Me: I am 40.

Vian: You know 40 is not that old for an adult.

Me: Really? How come?

Vian: I can count to 40 really fast and it doesn't even take that long.

He then proceeds to demonstrate how quickly he can count from 1 to 40.

## Hot Cocoa Part 2

Yoshi is making hot cocoa for everyone after our snow play day.

Me: I think I'm going to drink all the hot chocolate that Amma is making.

Vian (5yo): If you drink my hot chocolate, I'm going to punch you 5 million times in your face.

Me: You can't even count that high, Vian.

Vian: Ok then I'm going to punch you one hundred times.

## Confidence of a 5yo

I don't know how to play Minecraft. Vian (5yo) decided he's going to educate me. We're now playing real-world Minecraft in the front yard without a computer. He's narrating various aspects of the game as he's walking around the front yard. A leather armor, iron ingot, wooden pickax, bedrock and so on.

Then he delivers this pearl of wisdom.

Vian: Here's a good tip. When you're in the game don't mess with me. I'm ﻿invincible﻿ and I can ﻿fly﻿.

Then proceeds to extol the virtues of bedrock and diamond pickax.

## Bejeezus

The kids like to scare me by trying to jump out from under the covers and yell "BOO!". I like to pretend that I'm scared of their tactics. The other day I decided to return the favor by suddenly entering their room and yelling "BOO!". I managed to scare Vian and he started giggling in fear and shrunk back under his comforter.

Me: Hey Vian, looks like I scared the bejeezus out of you.

Vian: No! No! I'm not scared. I don't even have any bejeezus, so you didn't really scare any bejeezus.
