Wanna bet those male students all have coke bottle glasses and pocket protectors?
Wanna bet that 20 years from now some of them will have as much money as Bill Gates?
As an engineering student, I found math interesting. But my interest and skill set was statistics and data analysis, and linear algebra. The calculus and vectors was hard to visualize personally, while many males seemed to get that part immediately. (Related to hunting skills?)
When I switched to industrial engineering, I’d managed Calculus 1,2 and 3 - but it was HARD.
The statistics courses and linear algebra were a breeze. And of the math classes I took (past the first algebra class), they were the only math/engineering classes with any significant proportion of women. (30%, compared to 10-15% in other engineering classes).
Physics was easy for me except for the calculus, though that stumped lots of people of both genders. Astronomy, biology, other memorize this stuff science, women had strong representation.
If there is a gap, it is from visualization ability, not math ability.
