Thales' view that all of nature is based on the existence of a single ultimate substance, which he theorized to be water, was widely influential among the philosophers of his time. Thales thought the Earth floated on water. In mathematics, Thales is the namesake of Thales's theorem, and the intercept theorem can
The Seven Sages (Latin: Septem Sapientes), depicted in the Nuremberg ChronicleThe list of the seven sages given in Plato's Protagoras comprises: [1]. Thales of Miletus (c. 624 BCE – c. 546 BCE) is the first well-known Greek philosopher, mathematician, and astronomer.
The first known reference to the Seven Sages is in Plato's Protagoras, where they are said to have collectively authored the first two maxims. [ 6 ] [ 7 ] The names of the sages are given by Plato as Thales , Pittacus , Bias , Solon , Cleobulus , Myson and Chilon ; but in the works of later writers, some of these names are dropped and others ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
While Archimedes was taking a bath, he noticed that the level of the water rose as he got in, and he realized that the volume of water displaced must be equal to the volume of the part of his body he had submerged. This meant that the volume of irregular objects could be measured with precision, a previously intractable problem.
The pre-Socratic philosophers, starting with Thales, noted that appearances change, and began to ask what the thing that changes "really" is. The answer was substance, which stands under the changes and is the actually existing thing being seen. The status of appearances now came into question.
In mathematics, Thales is the namesake of Thales's theorem, and the intercept theorem can also be known as Thales's theorem. Thales was said to have calculated the heights of the pyramids and the distance of ships from the shore. In science, Thales was an astronomer who reportedly predicted the weather and a solar eclipse.
One of the earliest known references to lodestone's magnetic properties was made by 6th century BC Greek philosopher Thales of Miletus, [12] whom the ancient Greeks credited with discovering lodestone's attraction to iron and other lodestones. [13] The name magnet may come from lodestones found in Magnesia, Anatolia. [14]
