Of Geometry - After His Lecture
Harvard Teachers Crowded Round
Him For Further EIucdation.
Psychologists today are astonished
by William James Sidis. the ten-year-
Old student of Harvard. who startled
gray haired mathematical professors
by propounding some new theories of
the fourth dimension in Il lecture which
lie recently delivered at Cambridge,
Mass. before the Harvard Mathemat-
fcal club
Distinguished mathematical profess
ors from all over New England were
present and gaZed in wonder as the
rosy checked boy in short trousers
placed on the blackboard row after
row of figures to prove his difficult
and profound theories. Many of them
frankly professed their ignorance of
the subject Of which the boy talked so
glibly and again and again called on
ical theorem
Young Sidis, who was accompanied
Oy his father. DR.. Boris Sidis. the well
known psychologist, stepped to the
front and. with childish laugh be-
gan his lecture. He wore q red hand
kerchief such as is commonly worn by
~ - Wv - 'n'',! ''n'o'S anu Ia"
handwriting was that of Il child. But
his mind was far from childish. and
some of his ideas We're beyond the
comprehension of many Of his auditors.
