![]() ![]() This led Galileo to champion the Copernican heliocentric model, which had been published by the Polish polymath in 1543. Then there were the phases of Venus, which could not be accommodated by the traditional Earth-centric model of the universe. He also identified the existence of four previously unknown moons orbiting Jupiter, which was the first-time objects had ever been seen to orbit another body besides the Earth or Sun. His most crucial observations included the revelation that, contrary to Aristotelian principles, the Moon was not a smooth sphere but a rough textured object like the Earth, with its own depressions and mountains. Ultimately, Galileo was not alone in utilizing telescopes for this purpose, but he was very quick at publishing his results and understanding their implications. This provided unprecedented views of celestial objects and changed everything. The original telescope, like Lipperhey’s, offered three times magnification, but his subsequent versions first offered eight times and eventually 30 times magnification. He then set about refining his instrument. Although he was not the only astronomer to do this at the time, the success of his telescope won him a lifetime lectureship. Why Switching Your Phone To Airplane Mode Is Importantįollowing Lipperhey’s example, Galileo decided to make his own telescope and to turn its vision-enhancing powers to the heavens. Often remembered as a heroic figure who challenged the established worldview of his day, Galileo’s story is actually an important example of how concurrent developments in scientific thinking, technological development, and networks of knowledge come together. The early history of the telescope is tightly bound with the career of Galileo, whose work had lasting consequences for our understanding of the universe. One such experimenter was the Italian polymath Galileo Galilei who heard about Lipperhey’s invention while in Venice in June 1609. Lipperhey applied for a patent for his new device, which circulated across Europe allowing other early “scientists” to experiment with their own versions. ![]() This seems to be the first evidence of a telescope in historical record. Nevertheless, we can start to think about the story of telescopes, an instrument brought into existence by this history, as starting in the late 16 th and early 17 th centuries.Īs with other early technologies involving lenses, we are not certain who their first inventor was, but we do know that in 1608, a Dutch spectacle maker called Hans Lipperhey announced a new instrument that used lenses to make distant objects appear closer. To be sure, their development would not have been possible without far older advances in lens technologies and accompanying theories of optics, but this deeply fascinating and detailed history is too expansive to be captured here. Telescopes – those wondrous optical tubes – have changed the way we understand our world and its place in the cosmos. Few other objects are so easily identifiable, both in appearance and in terms of their intended use. Telescopes are arguably one of the most iconic scientific instruments ever invented. Lenses are extremely valuable, and they have played an important role in the History of Science, not least in the development of modern telescopes. For example, have you ever considered the history of lenses, and how they have extended our view of the universe? The development of this subtle technology not only allows us to examine the very small or to peer into the vastness of space, but they also play an important role in our everyday lives, such as in our cameras, on cinema projectors, or simply as the glass in our spectacles. ![]() There’s much that we take for granted in our modern world. ![]()
