The electric current CAUSED a magnetic field. This discovery led to the invention of electromagnet.
He did cause and effect
Christian Doppler is best known for his discovery of the Doppler effect, which describes the change in frequency of a wave for an observer moving relative to its source. This effect is widely used in various fields, such as astronomy and medical imaging, to understand motion and velocity. Doppler's work laid the foundation for understanding how sound and light waves can be affected by relative motion.
The cause of the slaves' discovery by the farmer is the dogbarking at them. What is an effect of the slaves' discovery?
Famous quote of Christian Doppler: "The effect, the cause, again the cause from the effect, the effect from the cause. Thus ever does the wheel of time revolve." Christian Doppler's parents were Johann Evangelist Doppler and Theresia Zacherl.
He discoverd the Doppler effect
It came from the mind of man. Man observing his world around him, noticing cause and effect, then inventing a language (mathematics) for describing these cause and effect relations. Without man, there is no physics in the universe.
that he was a great man
C. V. Raman was awarded the Nobel Prize for his work on the scattering of light and for the discovery of the Raman effect.
It created a stampede of people seeking instant wealth.
No they are not. But they are a bloody good band.
1921--Nobel Prize in Physics "for his services to theoretical physics and especially for his discovery of the law of the photoelectric effect."
They formed a strong diversion against religions (mainly Muslim and Christian). The crusades influenced power of the Catholic Church, political matters, commerce, feudalism, intellectual development, social effects, material effects, and promoted the famous voyages of discovery.
