female scientists

every time when I read the or magazine, it is so strange that they always invite some famous female scientists to write some tiny issues to support the feminism or to call for the proper rights for female coming into the science. although i do not have any bias to female, in my opinion, those magazine should not waste so much room, but to offer more opportunities for other hard-working scientists to express their ideas or results.
however, today when i surf on the Internet and pick up some information about the female Nobel prize laureates, i almost give up my former thought, because no matter how boring the feminists are, the truth is, there is still sexual discrimination in the science field.
here i would like to post some tables to support my conclusion.
