Studying science is a delicate balance. On the one hand, it is vital to stay firmly anchored in fact and proof, making logical deductions only from available information. On the other, without lucky strokes of inspiration and, occasionally, wild leaps of imagination, scientific progress would advance at a snail's pace.
Yet knowledge isn't all there is to science. While a good grounding in the basics is important, science is a subtle recipe of inquisitiveness, logic, creativity and, often, self-confidence. To me, there are few things more important for budding scientists than to nurture their way of thinking and analytical skills.
The greatest names in science have invariably risen to fame by coming up with novel ideas and conjuring up unexpected solutions to existing problems. Most often, this is not the result of raw intelligence, but rather a careful mix of open-minded creativity and down-to-earth scientific thinking.
