The new year is here! It's time for change and time for improvement.
1) Recycle
This might sound simple but aim to really recycle everything possible. Don't think that just one can of soda won't make a difference. It won't, but we can't have everyone thinking like that.
Humans have built and explored big things for many years. First it was the ocean now it's space. The next frontier will be on the nano scale. As technology grows smaller, the number of possible applications increases. A nano-scale steam engine has already been created. Although there are no applications for it yet, it creation was a big breakthrough that will lead the way for further developments.
