Cool, I just added a single grain of sand to a tonne of snow, now I have a tonne of sand. How convenient.
- ses1984 2y agoIf you add a single grain of sand to a tonne of snow, it’s not 85% sand.
- hinkley 2y agoSeems somebody slept through Intro to Logic.
- fwip 2y agoHow does that one grain become 85% of a tonne?
- pinkmuffinere 2y agoI don’t understand how you got that conclusion — 1 grain of sand is not 85% of the [ton of snow + 1 grain sand]
- sakras 2y agoI think OP wanted to construct “sand by induction”, but I also think you need more than one grain. If you have 9 grains of sand and add one snowflake, you now have something that’s 90% sand and is therefore 10 grains of sand. Take your 10 grains of sand and add another snowflake to create 11 grains of sand. Continue with each snowflake one by one, and you’ve inductively created a sand pile.
- timando 2y agoYou don't need to construct sand by induction. Just notice that snow has the right particle size to be considered sand.
