Foolish traditions and views
It was believed, not so long ago, that women are not cut out for research, and their scientific careers were seriously hampered. Needless to say, this stupid concept was propounded by men, and any justification of such deplorable views and traditions pushes us to doubt the sanity of those who do so. It was not until the turn of the 20th c. that the wind of normality started blowing. Regrettably, there are countries in which men are still no wiser, and turn their communities backward.
