Earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
Earth Observation
Earth observation (EO) is the gathering of information about the planet's physical, chemical, and biological systems via remote-sensing technologies, supplemented by earth-surveying techniques, which encompasses the collection, analysis, and presentation of data. Earth observation is used to monitor and assess the status of and changes in natural and built environments.
Observation
Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring.
Science
Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Observation
Quis custodiet ipsos custodes?
English equivalent: Who watches the watchmen?
Science
We’ve arranged a global civilization in which most critical elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.
Sir Ernest Rutherford from The Demon-Haunted World: Science as a Candle in the Dark (1996), 26.
Earth
Simonson, in rubber jacket and similar galoshes, bound with whip-cord over woolen socks (he was a vegetarian and did not use the skin of animals), was also awaiting the departure of the party. He stood near the entrance of the house, writing down in a note-book a thought that occurred to him. “If,” he wrote, “a bacterium were to observe and analyze the nail of a man, it would declare him an inorganic being. Similarly, from an observation of the earth’s surface, we declare it to be inorganic. That is wrong.”
Leo Tolstoy, Resurrection (1899), translated by William E. Smith, ch. 83.
