Hipparchus Mathematician Quiz: Father of Astronomy

1. What did Hipparchus use in calculating distance from earth to moon?

Trigonometry

Polynomials

Algebraic expression

Calculus

Hipparchus used trigonometry to calculate the distance from the earth to the moon. Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. By measuring the angles and using trigonometric functions such as sine, cosine, and tangent, Hipparchus was able to determine the distance to the moon. This method is still used today in various fields of science and engineering to calculate distances and angles.

2. Hipparchus was the founder of:

Geometric and Parallax Methods

Polynomials

Logarithms

Algebraic system

Hipparchus was a Greek mathematician and astronomer who made significant contributions to the development of trigonometry. He is often referred to as the "founder of trigonometry" because he was the first to create a table of chords, which was a precursor to the modern trigonometric functions. Hipparchus used these tables to solve problems in astronomy, such as determining the positions and distances of celestial bodies. His work laid the foundation for the study of angles, triangles, and the relationships between them, which is now known as trigonometry.

3. What was the Nationality of Hipparchus?

Turkish

Italian

Greek

Roman

Hipparchus was a Greek astronomer and mathematician who lived in the 2nd century BC. He made significant contributions to the field of astronomy, including the development of the first comprehensive star catalog and the discovery of the precession of the equinoxes. His nationality is Greek because he was born in Nicaea, which was a part of ancient Greece.

4. All of these are Hipparchus' occupations except:

Mathematician

Geographer

Astronomer

Physicist

Hipparchus was a renowned mathematician, geographer, and astronomer in ancient Greece. He made significant contributions to the fields of trigonometry and astronomy, including the development of the first known star catalog. However, there is no historical evidence to suggest that he was a physicist. Therefore, the correct answer is physicist.

Hipparchus started his scientific career before 141 BC.

Explanation

Hipparchus started his scientific career before 141 BC.

6. Hipparchus was born in Bythiania, it's now named as:

Russia

Slovakia

Turkey

Greece

Hipparchus was born in Bythiania, which is now named as Turkey.

Explanation

Hipparchus was born in Bythiania, which is now named as Turkey.

7. Hipparchus lived for his many years?

80

70

60

50

Hipparchus lived for 70 years because it is the closest option to "many years" compared to the other given options. The question implies that Hipparchus had a long lifespan, and out of the options provided, 70 is the highest number, indicating a longer life.

Explanation

Hipparchus lived for 70 years because it is the closest option to "many years" compared to the other given options. The question implies that Hipparchus had a long lifespan, and out of the options provided, 70 is the highest number, indicating a longer life.

8. His last observation was in the year:

150BC

127BC

500BC

145BC

The correct answer is 127BC because it is the only option that is closer to the present year compared to the other options. The other options are further back in time, so they cannot be the last observation.

Explanation

The correct answer is 127BC because it is the only option that is closer to the present year compared to the other options. The other options are further back in time, so they cannot be the last observation.
