Q & A

What is the historical preference of human beings when it comes to building structures?

Historically, human beings have preferred to build big structures, as evidenced by the pyramids of Giza and Mexico, Easter Island statues, and Stonehenge.

How has the concept of 'bigger is better' been challenged in the last century?

In the last century, the concept of 'bigger is better' has been challenged by the benefits of miniaturization, as demonstrated by the evolution of computers from large machines like the Howard Mark 1 to small, powerful devices like smartphones.

What is nanotechnology and what scale does it operate at?

Nanotechnology is the science of engineering materials, fabrication, and micro scale patterning at the molecular and atomic levels, operating at a scale smaller than 100 nanometers.

What is a nanometer and how does it compare to the size of a hydrogen atom?

A nanometer is one billionth of a meter, which is 10 times the diameter of a hydrogen atom.
