Happy Valentine’s Day!

Here is a good surface for today:

(x^2+9/4*y^2+z^2-1)^3 – x^2*z^3 – 9/(80)*y^2*z^3 = 0

And here is what it looks like in the Monroe 3D calc plotter.

Finally, a poem for you to use on that special someone written by David Feinberg:

I fear that I will always be
A lonely number like root three
A three is all that’s good and right,
Why must my three keep out of sight
Beneath a vicious square root sign,
I wish instead I were a nine
For nine could thwart this evil trick,
With just some quick arithmetic
I know I’ll never see the sun, as 1.7321
Such is my reality, a sad irrationality
When hark! What is this I see,
Another square root of a three
Has quietly come waltzing by,
Together now we multiply
To form a number we prefer,
Rejoicing as an integer
We break free from our mortal bonds
And with a wave of magic wands
Our square root signs become unglued
And love for me has been renewed.
