Telescope:
Telescope was invented by Hans Lippershey, a Dutch eyeglass maker, in the early 17th century. He applied for a patent for his invention in 1608, which was a simple refracting telescope. However, it is worth noting that Galileo Galilei is often credited with the invention of the telescope since he was the first to use it for astronomical observations.

Six Maximum Minimum Thermometer:
The Six Maximum Minimum Thermometer was invented by James Six, a Scottish instrument maker, in the 18th century. This thermometer is designed to record the maximum and minimum temperatures over a given period of time. It consists of two separate mercury thermometers, one to measure the maximum temperature and one to measure the minimum temperature.
The Six Maximum Minimum Thermometer is commonly used in meteorology to track temperature variations over a day or a specific period. It is a valuable tool for weather monitoring and analysis.
