    <h2>Haskell Code</h2>
    <p>
      Here is some code that I've written in <a href="http://haskell.org">Haskell</a>.
      These packages are available on <a href="http://hackage.haskell.org">Hackage</a>.
    </p>
    <ul>
      <li><a href="http://hackage.haskell.org/package/learn-physics">learn-physics</a><br />
	A library of functions for vector calculus, calculation of
	electric field, electric flux, magnetic field, and other
	quantities in mechanics and electromagnetic theory.
      </li>
      <li><a href="http://hackage.haskell.org/package/cyclotomic">cyclotomic</a><br />
	The cyclotomic numbers are a subset of the complex numbers
	that are represented exactly, enabling exact computations and
	equality comparisons. They contain the Gaussian rationals
	(complex numbers of the form p + q i with p and q rational),
	as well as all complex roots of unity. The cyclotomic numbers
	contain the square roots of all rational numbers. They contain
	the sine and cosine of all rational multiples of pi. The
	cyclotomic numbers form a field, being closed under addition,
	subtraction, mutiplication, and division.
      </li>
    </ul>
