What do you think of girls success in science & technology world!?

There should be no such mentality regarding education. Sure, females show a slight disparity in logic/reasoning/math scores in our country - but in countries like Japan, where women are not EXPECTED to show such a disparity, they don't! Our culture raises little girls in the expectation that they will fail in science and math ... and so a lot of them do. There's no doubt, however, that women can and have achieved both scientific and mathematical greatness: Ada Lovelace is known as one of the first computer engineers, Theano was the discoverer of the 'golden ratio', Sofia Kovalevskaya was a great mathematician who did great work on completing the method for rotating solids and she was the third woman ever to be allowed a position as a professor, Yvonne Barr is a virologist and discoverer of the Epstein-Barr virus ........the list goes on and on and on!!! Don't be discouraged by the ism of your 'friends'.
