Avoiding Square Roots

The cluster revolves around a mathematical method or construction that claims to avoid explicit square roots, but commenters debate its validity by pointing out hidden square roots, such as sqrt(2) for square diagonals, and ambiguities in the term 'square'.

Bah! Just square & take the square root!

Koshkin • Jun 27, 2020 • View on HN

Damn, now I need to understand the square root.

rocqua • Aug 30, 2017 • View on HN

How does he deal with the diagonal of the square? because that needs sqrt(2).

That actually does square the circle.

ziofill • Feb 23, 2025 • View on HN

This is amazing, but there are a lot of 2's hiding in those sqrt symbols

Hmm, isn't square normally x*x?

You are thinking of squares, not of powers of 2.

What does it mean to "understand" the square root?

blharr • Nov 22, 2024 • View on HN

Pretty sure you followed the thread wrong. They only mentioned the square root in response to you?

I know I’m asking for a square that’s also a circle
