“The idea has been to make science ____ to everybody,” said Prakash.

While researching methods for identifying infectious diseases in Thailand in 2011, Prakash came across an expensive microscope that was ____ for malaria testing but was unused.

____ began wondering.

A cheap, strong microscope ____ save thousands of lives.

After he returned to Stanford University, where he was a ____, he started to reflect on the idea.

It was not until he met Jim Cybulski that his idea of an affordable and accessible microscope began to ____ shape.

A graduate student at Stanford, ____ was looking for ways to apply his engineering background to make a difference in the real world.

After hearing ____ vision, Cybulski quickly recognized its potential and was eager to contribute.

For a microscope to function properly, it must ____ certain minimum requirements.

These include an eyepiece, a tube through ____ the viewer looks, and a lens for magnification.

The microscope must also have a component that can hold a specimen and move from side to ____ to explore different areas of the specimen.

Furthermore, a mechanism to bring the specimen into focus, usually ____ by moving it closer to or farther from the lens, is necessary.

Finally, a light source is required to illuminate the ____.

An ideal microscope would be ____ with the best performing materials and mechanisms for each component.

However, such a microscope would likely be ____ expensive.

On the ____ hand, a cheap microscope may not be able to deliver high performance.

____ and Cybulski experimented with various designs and materials in order to find a suitable compromise.

While many manufacturers might have settled for a middle ground between these two extremes, Prakash and Cybulski were determined to ____ a microscope that was both inexpensive and high-performing, while remaining accessible to all.

After drawing various designs on paper, Prakash and ____ realized that paper could be an excellent medium for their microscope.

It was cheap, easy to cut and ____ with precision, and widely available.

They faced many challenges during their attempts to ____ the perfect design.

Ultimately, they settled on waterproof cardboard paper with a small glass ball ____ and named their invention the Foldscope.
