An algebraic surface<\/a> is a set of solutions to the general equation \"\"f(x,y,z)=0 where f is a polynomial in the variables x,y and z.\u00a0 For example if you set f to the following polynomial<\/a><\/p>\n

\"Equation<\/p>\n

then the set of points x,y and z that satisfy \"\"f(x,y,z)=0 forms a sphere of radius 1.\u00a0 You can get much more interesting surfaces than a sphere though.\u00a0 For example, set<\/p>\n

\"Kiss<\/p>\n

and you’ll get something known as the kiss surface – so called because the bottom section resembles a Hershey’s Kiss<\/a>. Wolfram Alpha knows all about this surface and if you wolf Kiss Surface<\/a> you’ll get a whole load of mathematical information about it along with the plot below.<\/p>\n

\"Plot<\/a><\/p>\n

One algebraic surface I have looked at in the past<\/a> is the Heart Surface<\/a> and it’s pretty obvious to see where it gets its name from.<\/p>\n

\"The<\/a><\/p>\n

At the time of writing, Wolfram Alpha knows about 129 different, named algebraic surfaces<\/a> but for some of them it can be a little harder to work out how they got their name. Does anyone know why the one below is called the Flirt Surface<\/a> for example?<\/p>\n

\"The<\/a><\/p>\n

Other interesting ones have names like Heaven and Hell<\/a>,Citrus<\/a>, Star<\/a> and Plop<\/a>!<\/p>\n

This functionality is very nice indeed but for it to be really impressive I’d like to see a bit more (I wouldn’t be me if I didn’t want more). For example, it would be great if I could rotate each surface with the mouse – just as I can with 3D images in Mathematica. I’d also like to see more information on each surface such as how it got it’s name or the Mathematica code needed to produce the plot.<\/p>\n

What’s your favourite algebraic surface and what extra functionality would you like to see in this area?<\/p>\n","protected":false},"excerpt":{"rendered":"
