Professor McBride expands on the recently introduced concept of the wave function by illustrating the relationship of the magnitude of the curvature of the wave function to the kinetic energy of the system, as well as the relationship of the square of the wave function to the electron probability density. The requirement that the wave function not diverge in areas of negative kinetic energy leads to only certain energies being allowed, a p...more

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

In this lecture Professor Sylvia Ceyer moves on from the wavelike properties of light, to the particle-like nature of light. To do so she covers the photoelectric effect in detail, discussing threshold frequency and kinetic energy vs. frequency. Planck's constant is discussed. The lectures concludes with a discussion of photon momentum and its relation to wavelength.

Neutral evolution occurs when genes do not experience natural selection because they have no effect on reproductive success. Neutrality arises when mutations in an organism's genotype cause no change in its phenotype, or when changes in the genotype bring about changes in the phenotype that do not affect reproductive success. Because neutral genes do not change in any particular direction over time and simply "drift," thanks in part to the...more

William Sahlman, professor at Harvard Business School, asserts that although individuals are important, teams are the central unit of entrepreneurial success. Indeed, Sahlman argues that the reason why many companies succeed is because of the team, not any particular individual, and so entrepreneurs should think carefully about breaking up teams as well as the effect that replacing an individual has on a team.

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.

Abortion is very common both worldwide and in the US. There is one abortion for every 3.2 live births. In places where contraception is not used, abortion is used as birth control. Neither legal nor religious proscriptions have a strong effect on abortion rates. In countries where abortion is illegal, maternal death rates are extraordinarily high. Legal, medically done abortions are safer than getting pregnant. Psychological responses depe...more

Waldorf believes it is important to be self directed and follow one's passion. Assessing risk, having success in past endeavors, and finding good people can mitigate the effect of following the path less traveled.

Early Modern England: Politics, Religion, and Society under the Tudors and Stuarts (HIST 251)In this lecture Professor Wrightson examines the problem of order in early modern society, focusing on crimes of violence and upon property crime. In examining violence, he notes the existence of special cases geographically (the borderlands) and socially (aristocratic violence) before looking at the lower (and gradually declining) levels of homici...more
