neglect of the square
is indefensible. Since you cannot integrate with the squared term in
place, your whole solution fails."

"Not necessarily. We'll go back to 29, and put in sine squared theta
minus one equal to z sub four. That gives us a coversed sine in 30,
and then we integrate...."

Thus the argument raged, and all the assistants whose work was not
too pressing gathered around unobtrusively, for it was from just such
fierce discussions as this that the ultra-radio and other epoch-making
discoveries had come into being. Yard after yard of calculator paper
was filled with equations and computations. Weirdly shaped curves
were drawn, with arguments at every point--arguments hot and violent
from Brandon, from Westfall cold and precise, backed by lightning
calculations and with facts and diagrams culled from the many abstruse
works of reference, which by this time literally covered the bench and
overflowed upon the floor.

It was in this work that the strikingly different temperaments and
abilities of the two scientists were revealed. Brandon never stood
still, but walked around jerkily, chewing savagely the stem of an
ancient and reeking pipe, gesticulating vigorously, the while his keen
and agile mind was finding a way over, around, or through the apparently
insuperable obstacles which beset their path; by means of mathematical
and physical improvisations, which no one not inspired by sheer genius
could have evolved. Westfall, seated quietly at the calculator,
mercilessly shredded Brandon's theories to ribbons, pointing out their
many flaws with his cold, incisive reasoning and with rapid calculations
of the many factors involved. Then Brandon would find a remedy for each
weakness in turn and, when Westfall could no longer find a single flaw
in the structure, they would toss the completed problem upon a table
and attack the next one with unabated zeal. Brandon, in his light
remark that the two made one real scientist, had far understated
the case--those two brains, each so powerful and each so perfectly
complementing the other, comprised the master-scientist who was to
revolutionize science completely in a few short years.

To such good purpose did they labor that the calculations were
practically finished by the time they reached the earth. There the ship
was serviced with a celerity that spoke volumes for the importance of
her mission--even the _Aldebaran_, the dazzlingly gold-plated queen of
the fleet, wait
