Equipped with his five senses, man explores the universe around him and calls the adventure Science.

The history of astronomy is a history of receding horizons.
Interpretation
The evolution of astronomy reflects our expanding understanding of the universe and its limits.
Edwin Powell Hubble's quote suggests that the field of astronomy has continuously pushed the boundaries of our knowledge, where each discovery leads to further questions and a deeper appreciation of the universe's vastness. As astronomers uncover new celestial phenomena, they realize that what was once deemed the edge of our understanding is only a stepping stone to more profound mysteries yet to be explored.
In practice
In a lecture about the evolution of space exploration and our understanding of the universe, this quote can highlight the continuous journey of discovery.
Equipped with his five senses, man explores the universe around him and calls the adventure Science.
At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be oppressed.
Equipped with our five senses - along with telescopes and microscopes and mass spectrometers and seismographs and magnetometers and particle accelerators and detectors sensitive to the entire electromagnetic spectrum - we explore the universe around us and call the adventure science.
There we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial.
All nature is a vast symbolism: Every material fact has sheathed within it a spiritual truth.
Observations always involve theory.
Any scientist who can't explain to an eight-year-old what he is doing is a charlatan.
NASA has spin-offs, and it's a huge and very impressive list, including accurate and affordable LASIK eye surgery.
It's a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.
Measure what is measurable, and make measurable what is not so.
If our local, observable universe is embedded in a larger structure, a multiverse, then there's other places in this larger structure that have denizens in them that call their local environs the universe. And conditions in those other places could be very different. Or they could be pretty similar to what we have here.
Biologically inspired materials could revolutionize materials science. People looking at spider silk and abalone shells are looking for new ways to make materials better, cheaper, and with less toxic byproducts.
