child use all of his or her senses to understand it. According
to the Exploratorium’s Noel Wanner and Paul Doherty,
scientists aren’t so different in their curiosity. "It’s
the tools that are different," they write in

that scientists use to extend their senses into ranges far
Scientific research relies on powerful extensions of our eyes
and ears, and scientists employ these tools in many ways.

The tools used for scientific research can be both predictably
complex and surprisingly simple. The

When it comes to studying
life, often the tools are living things themselves,

to answer a researcher’s questions.
Tools sometimes have an evolution of their own. They can reveal
new things to us about the world, prompting us to ask new
questions whose answers require new tools or enhancements
of older ones. For example,
