Dieser Podcast richtet sich an Schülerinnen und Schüler der Klassen 7 bis 13. In regelmäßigen Abständen kann man sich einen Audio- und Videopodcast herunterladen und anhören, bzw. ansehen. Im Podcast wird eine mathematische Startidee präsentiert, die zu eigenem Arbeiten anregen kann. Außerdem gibt es auf der Homepage zu jeder Podcast-Folge ein Arbeitsblatt, das die Startidee noch einmal aufgreift. In einem Forum besteht schließlich für die Schülerinnen und Schüler die Möglichkeit, sich über Fragen und eigene Ideen auszutauschen.
Kreativwerkstatt Mathematik Podcast
Established in 1816, The Fitzwilliam Museum is the principal art museum of the University of Cambridge. These podcasts offer the chance to learn more about the Museum's treasures, which range from Ancient Egyptian, Greek and Roman antiquities to the arts of the 21st century, with exclusive introductions to exhibitions, interviews with expert curators and previews of Museum events. (This the standard video version of our podcast, suitable for iPods. Elsewhere, an audio-only podcast in mp3 format is available. Please check our website or the iTunes store for alternative versions.)

Being - いきていること展
The Limited Fork show featuring POAMs: Products of Acts of Making in fulfillment of principles of Limited Fork Poetics: the study of interacting language systems, where the visual, sonic, tactile, and olfactory meet to form and reform (compelling) structures. Where focus on an intensely stabilizing area can still produce (forms of) sonnets that will maintain a particular form for only a limited period of time after which other structure(s) emerge, some of the emergence occurring across physical, sensory, and other dimensions.
This podcast is the place where POAMS, products of acts of making, will evolve, for the idea (as well as the poams that come out of the idea) is dynamic, seeking ways to fulfill the need for expression that coincides with unfolding understandings of existence. At the end of one of the branching roots of LFP and at the tip of one of the branches is belief in the pleasure of making things, a pleasure increased by acts of making that understand and try to take advantage of the range of what is possible and available.
BY FOCUSING ON INTERACTIONS, THE WHOLENESS OF THE ORGANISM IS EMPHASIZED.
The LFP experiment will showcase successes and failures, for the dead ends, the branches that do not bear sweet fruit, edible fruit, or any fruit at all, nevertheless contribute meaningfully to the recognizable structure of the tree. Perhaps the beauty of the tree depends on the presence of some dead ends.
Every week, there will be a visual or sonic episode (a branch) that reflects the current status of the ongoing study of interacting language systems. The LFP show will always present what is within its changing limits. Not (just) poems, but POAMS.

Podcsat from 2008 of lecture on Raman spectroscopy. This is in place of the 11/9 lecture given about Raman spectroscopy, for which the audio didn't record properly.
Raman Scattering
01:15:09
Podcsat from 2008 of lecture on stimulated Raman scattering. This content was not covered in class this semester. This is for your interest only and will not be covered on exams.
Stimulated Raman Spectroscopy
01:15:11
We look at how saturation causes hole burning in a spectral line, and measurement techniques such as lamb-dip spectroscopy and intermodulated fluorescence that can take advantage of this for doppler-free measurements.
Nonlinear Spectroscopy
01:17:12
We look at basic methods of emission spectroscopy including laser induced fluorescence, resonant enhanced multi-photon emission (REMPI), intermodulated fluorescence and stimulated emission pumping.

WE look at basic techniques of absorption spectroscopy including direct detection, frequency modulation, intracavity absorption and cavity ringdown spectroscopy.
Absorption Spectroscopy

We look at how the natural lifetime of an energy level produces a Lorentzian line profile and how the natural linewidth can be broadened by Doppler broadening, pressure broadening, transit time broadening and saturation broadening.

We look at how interferometers can be used to measure wanelength.

We consider the advantages and disadvantages of three classes of photodetectors: photodiodes, photomultiplier tubes and thermal detectors.

We use the classical electron oscillator model to derive the functional form of the index of refraction in material as well as the absorption, which we relate to the cross section.
