The USDA once wanted to make cows produce milk faster, to improve the
dairy industry.

So, they decided to consult the foremost biologists and recombinant
DNA technicians to build them a better cow. They assembled this team
of great scientists, and gave them unlimited funding. They requested
rare chemicals, weird bacteria, tons of quarantine equipment, there
was a horrible typhus epidemic they started by accident, and, 2 years
later, they came back with the "new, improved cow." It had a milk
production improvement of 2% over the original.

They then tried with the greatest Nobel Prize winning chemists around.
They worked for six months, and, after requisitioning tons of chemical
equipment, and poisoning half the small town in Colorado where they
were working with a toxic cloud from one of their experiments, they
got a 5% improvement in milk output.

The physicists tried for a year, and, after ten thousand cows were
subjected to radiation therapy, they got a 1% improvement in output.

Finally, in desperation, they turned to the mathematicians. The
foremost mathematician of his time offered to help them with the
problem. Upon hearing the problem, he told the delegation that they
could come back in the morning and he would have solved the problem.
In the morning, they came back, and he handed them a piece of paper
with the computations for the new, 300% improved milk cow.

The plans began:

Consider a spherical cow......"
