It doesn't say to use salt.

>> No.4423567

>>4423563
It's sodium on the roof, not sodium chloride. One's a metal that reacts violently with water, and the other's a salt that will dissolve and lower the freezing point, making ice melt off your roof.

>> No.4423569

>>4423549
The fact that the roof isn't salt. It's sodium. Slight difference there.

it says to use Na, as opposed to Na^+.

Large difference, that would be sodium metal, which when reacted with water fucking explodes.

hurr durr
yes, why??
My guess is that every segment of the perimeter is not a curve but a set of lines, which would happen to be 4/pi of the curve, always.
Say every corner of the angle is a set of 2 segments of lenght 1/2 holding a curve of lenght pi/4 thus 1!=pi/4
the next iteration would be 2 segments of 1/4 (2*1/4)=1/2 holding a curve of pi/8
and so on. the decrease rate would be constant, and the relation between pi and the segments would always keep the same proportion.

it says sodium(SA) not sodium chloride (table salt) sodium reacts great with water... it explodes/bursts into flames...

This method only touches the circle tangentially 4 times. Even extrapolated to infinity, you have corners poking the outside of the circle. If you integrate the lengths between the points, you'll get to pi
