1 What is Bode's law about?
A different interpretation of Newton’s gravitation
Measurement of the distance between the sun and the earth
Distance of planets from the sun
Prediction of how many planets there are
2. Why does the professor explain Bode's Law to the class?
To explain some patterns in numbers
To explain how the asteroids belt was discovered
To explain how gravitational forces influence the planets
To explain how telescope helped finding Uranus
3. How does the professor introduce Bode's Law?
By demonstrating how it is derived mathematically
By describing the discovery of Uranus
By drawing attention to the inaccuracy of a certain pattern
By telling the names of several of the asteroids
4. According to the professor, what two factors contributed to the discovery of the asteroid Ceres? Click on 2 answers
Improved telescopes
Advances in mathematics
The discovery of a new star based on Bode’s law
The discovery of Uranus based on Bode’s law
5. What does the professor imply about the asteroid belt?
It is farther from the Sun than Uranus
Bode believed it was made up of small stars
It is located where people expected to find a planet
Ceres is the only one of the asteroids that can be seen without a telescope
6. Why does the professor say “This pattern is known as Bode’s Law. Um, it isn’t really a scientific law, not in the sense of predicting gravitation mathematically or something,”
To introduce an alternative application of Bode's Law
To give an example of what Bode's law cannot explain
To describe the limitations of gravitational theory
To contrast Bode's Law with a real scientific law
7. What can we infer from “But I kind of have to skip the one after Mars for now.”
He will explain how the spot was filled later
No planet has been found in that spot so far
The professor feels that the correspondence between Bode’s numbers and the placements of planets too obvious
The professor feels that Bode’s law doesn’t work after all since no planets exist in that spot
8. How was Ceres discovered?
it was discovered by accident when people started to look at the night sky with telescopes
It was discovered immediately after Bode proposed his law
People searched for it at a specific spot
It was discovered when people looked for Uranus.
9. Based on the lecture, which one of these can we infer was available to astronomers around the time when Bode proposed his law?
knew about the existence of Uranus
knew Ceres was an asteroid
knew how to measure the distance of the sun from the earth
knew how to use telescopes to discover Jupiter and Saturn
10. Arrange the events mentioned in the lecture in the chronological order
Asteroid Belt was discovered
Uranus was discovered
Bode discovered a pattern in planets’ distances
