  1. Science projects can be expensive. Just look at how costly NASA is and even putting NASA aside, other science projects are expensive too such as the Hadron Collider in France/Switzerland. And back to NASA, they're now apparently going to try to create Oxygen on Mars, which will be expensive. Anyway, as expensive as pursuing science projects might be, a great benefit to putting more money into science is that doing so will create more jobs. If we're going to pursue science projects we obviously need people to do the projects and that means more jobs, so pursuing more science projects would mean more employment.
  2. I am doing research into colored lights for this project I want to do. When you switch on an ordinary flashlight it emits a plain white light which is all the colors but Im interested in lights that only emit light of one color. Now at the most basic level having such a light can be very simple, all you have to do with your flashlight is put something on it to make it a certain color, for instance if you want your flashlight to be red you could just fit a red balloon over the end of the flashlight and it will make the light red. To the best of my knowledge that works by filtering, the red balloon filters out all the colors from the flashlight except red and so you've got red light. Anyway, I don't want something so simple. Im interested in a special light that only emits a certain color without a filter. I believe they do make diodes that operate like that. Im not sure that's how traffic lights work or if traffic lights use filtering much the same way as fitting a red balloon over an ordinary flashlight but the reason Im asking is this project Im working on, I want to make a special type of flashlight.
