Dr Murdoch is demonstrating the scientific attitude of humility.
Historians of science support the idea that scientific attitude consists of three main components: humility, curiosity and scepticism. Curiosity refers to the intense need and passion to test and question in order to understand or find a solution. Skepticism refers to the attitude of doubting everything in a sensible way. Finally, humility is the attitude of believing that facts and truth matter more than your own opinion.
This attitude helps modern scientists to test and evaluate each other's scientific conclusions.
Answer:
spectroscope is a device that helps us find out the content of stars by splitting light into spectra and wavelengths. It usually disperses white light from a star and splits them into a very wide spectrum of colors. It grants diffraction to an optical component with a periodic structure that splits and diffracts light into several beams. This beams travels in different directions and different colors will be seen. When we wish to attain a resolution closer to the designed value we need to install additional slit at the inlet of the spectroscope.
Explanation:
The spectroscope is also known as spectrometer. It functions by breaking down lights into different wavelengths which is made up of. Light incoming into a spectroscope usually carry spectral information. A spectroscope consists of a slit, a dispersing element, a focusing objective and a collimator.
Answer:
d. Serfdom
Explanation:
The statement is describing the serfdom conditions that were common in Feudal Europe of the Middle Ages.
Serfs are almost slaves who enjoy only some nominal liberties over their enslaved counterparts. Serfs have to work the land of their lord, pay the surplus production as a tax, and cannot leave the land without their lord's permission. They do not enjoy the same rights as their lord, and can be told or obliged to do anything by their superior.
