Don't try to make science cool! Anything you try to make cool won't be! It's a scientific fact!
Seriously though... someone should tell college professors to stop making science hard. If science was learnable and its concepts were more approachable then people would enjoy it. A lot of people drop out of hard sciences because professors want to make students "earn" it as well as "learn" it, like they did back in the day. I loved my science courses. I never understood why I had to run the engineering math gauntlet. The business math courses would have been a lot more practical and useful for myself and just about everybody I went to school with.
I have a degree in physics... Science shouldn't be hard if you had instructors that are focused on making students understand. Physics is a good example... teachers that insist on drawing a picker and can explain concepts well make all the difference. Want more scientists... then teach science more effectively... hard = doesn't understand teacher
