How has science and technology helped the emancipation of women?How has science and technology helped the emancipation of women?
One interesting point is how both science and technology have emancipated women by virtue of women becoming and working as scientists and technicians over the last century and a half.
Women have had a better life expectancy because of the developments of germ theory in the mid-1800's -- the cause of infection became known; hygienic practices were introduced so the women started to survive childbirth rather than not. As medicine improved life expectancy, women were free to not just be mothers, as most of them were condemned because of high infant and childbirth mortality rates, but participants in the rest of the culture as well.
The advances made in medicine and healthcare have had a tremendous impact on the emancipation of women. Having a child certainly changes the course of a woman's life, so being able to have control over this factor by using (or not using) birth control certainly gave women more freedom, power, and control over their lives. Furthermore, health and safety improvements in the healthcare setting have improved the way women are cared for during childbirth, and throughout life.
The obvious example to me is birth control. With the invention of birth control pills, women came to be able to have much more control over when they became pregnant. This allowed them to, for example, be able to go out and work more. This, in turn, gave them more economic independence and made them much less dependent on men.
The simple answer is that chores that were normally women's work, like cleaning, have gotten more and more automated. Washing machines made laundry do itself. Dishwashers do the dishes. Refrigerators and frozen foods reduce cooking and shopping time. Women also can do jobs where strength is not as important due to technology.
I would add that women are able to have a stronger voice and reach more people because of technology. Given the electronic movement, women are able to reach more people and cause greater "ripples" in the water. They can come together in ways which they were not able to before.
