Another one that came up two nights ago & I think this is really interesting + I had difficulty with it.



"Abah, what shape is one dee?"



"One dee?"



"Yes 1-D, like 2-D & 3-D"



Trying to see whether she knew what she's talking about, I asked. "What shape is 3-D?"



"Hmmm... you know like us.... hmmm.... a cube"



"How about 2-D?"



"A square"



Buying some time, "That's good".



And she persisted, "So, what shape is 1-D?"



"Let me think - a dot, a very small dot". I was thinking along the line of something without width or depth.



"How small?"



"Very-very small"



"Is it smaller than germs?"



"Smaller"



"Is it real"



"Yes it is" - without much thinking.



"Wow, germ is the smallest thing I know"



Then trying to be a dad whole tell new things to her child & take her off the 1-D subject.



"Actually atom is smaller than germs, everything is made up of atom - all these small atoms"



"Wow, are they smaller than the 1-D dot?"



argghhh...... "not really. You can only imagine the 1-D dot."



"But is the 1-D dot real then?"



I did say real. "No, not really - you can only imagine it"



"okay, maybe after this you can tell me a 4-D shapes"



"4-D shapes are not real & you cannot imagine them" - I guess you actually can mathematically.



"Abah, can you tell me about 100-D shape one day?"



"hmmmmmm, is it not your bedtime yet?"
