Science
has been dominated by men for...well, a very long time, much like
most of Western society. While that domination has gradually loosened
over the last century, it still very much exists today, with women,
on average, still having to overcome more obstacles than men in order
to pursue a career in science. Because
of this dominance, when looking at the history of science, as Cosmos
has been doing in addition to explaining the science, it is
inevitable that the majority of names will be those of men. However,
they most certainly shouldn’t be all
men’s names, for there have been many women working in science over
the centuries (not even just this past one), and many women have made
important discoveries. Yet, how many can we name off the tops of our
heads? I’m embarrassed to admit that I can’t name many. Marie
Curie comes to mind almost immediately, but after that, I have to
stop and think in order to come up with a pitifully small sample. Yet
asked to name men (or just scientists in general), numerous come
immediately to mind before I have to stop and think a bit:
Copernicus, Galileo, Newton, Einstein, Hawking, Sagan, Tyson... As I
said, there are more
men, but surely I ought to be able to remember a few more women.
“Sisters
of the Sun”, the eighth episode of Cosmos,
takes steps to rectify that a little bit by introducing us to some of
the pioneers of astronomical spectroscopy: Annie Jump Cannon,
Henrietta Swan-Leavitt, and Cecilia Payne. Cannon developed the
system used to classify stellar bodies and Swan-Leavitt the method to
determine the distance to the stars and thus the size of the
universe. Cecilia Payne took the work of Annie Jump Cannon and
deciphered her spectral analyses to determine the composition of
stars—particularly the ground-breaking discovery that hydrogen and
helium are about a million times more abundant than any other
element.
