Doppler Effect, Binary Stars, Neutron Stars and Black Holes. Doppler shift is introduced with sound waves, then extended to electromagnetic waves (radiation). The Doppler shift of stellar spectral lines and/or pulsar frequencies provides a measure of the line-of-sight (so-called radial) velocity of the source relative to the observer. Combined with Newton's law of universal gravitation, this can lead to the orbital parameters and the mass ...more

Competition among species, or interspecific competition, can have an even greater effect on selection than competition within species (intraspecific competition). This is often the case in lower density populations. Different species can have positive, neutral, or negative effects on each other's fitness, and the effect species 1 has on species 2 is not necessarily the same that 2 has on 1. The effects that cohabiting species have on each ...more

This lecture reviews selected concepts previously covered in lectures 16 through 24: one-dimensional collisions, simple harmonic oscillation (SHO) of a suspended rod, conservation laws for a satellite s orbit, the Doppler shift, and pure role.

One of the major cultural consequences of the second plague pandemic was its effect on attitudes towards death and the "art of dying." As a result both of its extreme virulence and the strictness of the measures imposed to combat it, plague significantly disrupted traditional customs of dealing with death. This disruption made itself felt not only in religious belief and burial practices but also in art, architecture and literature. Europe...more
