Science sharpens our minds to discern proper evidence from flimflam, to tell good experimental design from bad and to separate statistics from exaggerations. More than that, it reveals the beauty and intricacy woven into the very fabric of reality.

In this article, I suggest some easy and fun ways for your family to explore science together.

5 Traditions for Exploring Science

Because if it were green, we wouldn’t know where to stop mowing

Why is the sky blue? Everyone supposedly knows, but just about everybody gets it partially wrong. Don’t feel bad, though; the answer has so many parts, it took philosophers and scientists from Aristotle to Maxwell to answer it.

We tend to think of nanotechnology as the stuff of the future, but it’s already here, in hundreds of consumer products and industrial applications. As progress in this minuscule world has accelerated, concern for the environment and for public health has led to a call for green nanotechnology—approaches that accentuate the positive and eliminate the negative. In this article, we’ll take a tour of how these many approaches are playing out.

How is green nanotechnology being used?

Within its figures and formulas, the secular perceive order and the religious catch distant echoes of the language of creation. Mathematics achieves the sublime; sometimes, as with tessellations, it rises to art.
