Story Development in Cinematography
First off, I’ve got to argue for the use of the word “cinematography” over “camera”. One is to utilize a word I would like to further unpack. Another is to utilize a word that simply implies a relationship to another art form entirely – photography. I often say to my students that some cinematographers initially come from the lighting point of view and some come from the camera, but ultimately what great cinematographers do is understand a story (not just a moment that tells a story – there is a significant difference) – and tell it. If I say that storytelling is the most and primary function of a cinematographer, then how do we teach storytelling to our students in a classroom? Obviously it is possible to teach them tools of “photography” – lenses/optics, composition, chemistry, sensitometry etc. and lighting – this is an HMI, this is flicker, memorize WAV, etc. However, how do we teach them how to tell a story with these tools? I have been working the last few years on teaching my students story development tools that are appropriate for cinematographers. Tools which as they go forward into their own practice have begun to give real results in terms of not only storytelling, but in the students creating their own relevant visual styles. For them to utilize these tools they need to engage not only in pre-production time, but in story development time – which is a period rarely engaged in at the student level, but is crucial if we want them to become anything other than the takers of pretty pictures
New Theory of the Earth
New Theory of the Earth is an interdisciplinary advanced textbook on all aspects of the interior of the Earth and its origin, composition, and evolution: geophysics, geochemistry, dynamics, convection, mineralogy, volcanism, energetics and thermal history. This is the only book on the whole landscape of deep Earth processes that ties together all the strands of the subdisciplines.
This book is a complete update of Anderson’s Theory of the Earth (1989). It includes dozens of new figures and tables. A novel referencing system using Googlets is introduced that allows immediate access to supplementary material via the internet. There are new sections on tomography, self-organization, and new approaches to plate tectonics. The paradigm/paradox approach to developing new theories is developed, and controversies and contradictions have been brought more center-stage.
As with the Theory of the Earth, this new edition will prove to be a stimulating textbook for advanced courses in geophysics, geochemistry, and planetary science, and a supplementary textbook on a wide range of other advanced Earth science courses. It will also be an essential reference and resource for all researchers in the solid Earth sciences

Lord Coke, the Restatement, and Modern Subsurface Trespass Law
The First Restatement of Property provides that “‘property’ . . . denote[s] legal relations between persons with respect to a thing.” The “thing” considered in this article is the subsurface of real property, and the legal relationship involved in the extent to which persons may deal with invasions of their right to exclude trespassers is a fundamental incident of property ownership, this right, like other incidents, neither is nor should be absolute. The precise focus of this article is to consider how courts have treated subsurface invasions and to argue that the Second Restatement of Torts, which states that any subsurface intrusion is actionable, should be revised. The right to exclude trespassers from the subsurface of real property should be much more limited: subsurface trespass should not be actionable whenever the trespasser’s subsurface intrusion accomplishes an important societal need (including private commercial needs) if the subsurface owner suffers no actual and substantial harm. And because courts have largely refused to find harmless deep subsurface invasions actionable, the ALI should consider whether the Second Restatement of Torts, which essentially embraces Lord Coke’s ad coelum doctrine, accurately reflects the trend of subsurface trespass case law.The Kay Bailey Hutchison Center for Energy, Law, and Busines
Self-gravity, self-consistency, and self-organization in geodynamics and geochemistry
The results of seismology and geochemistry for mantle structure are widely believed to be discordant, the former favoring whole-mantle convection and the latter favoring layered convection with a boundary near 650 km. However, a different view arises from recognizing effects usually
ignored in the construction of these models, including physical plausibility and dimensionality. Self-compression and expansion affect material properties that are important in all aspects of mantle geochemistry and dynamics, including the interpretation of tomographic images. Pressure
compresses a solid and changes physical properties that depend on volume and does so in a highly nonlinear way. Intrinsic, anelastic, compositional, and crystal structure effects control seismic velocities; temperature is not the only parameter, even though tomographic images are often
treated as temperature maps. Shear velocity is not a good proxy for density, temperature, and composition or for other elastic constants. Scaling concepts are important in mantle dynamics, equations of state, and wherever it is necessary to extend laboratory experiments to the parameter
range of the Earth's mantle. Simple volume-scaling relations that permit extrapolation of laboratory experiments, in a thermodynamically self-consistent way, to deep mantle conditions include the quasiharmonic approximation but not the Boussinesq formalisms. Whereas slabs, plates, and the upper thermal boundary layer of the mantle have characteristic thicknesses of hundreds of kilometers and lifetimes on the order of 100 million years, volume-scaling predicts values an order of magnitude higher for deep-mantle thermal boundary layers. This implies that
deep-mantle features are sluggish and ancient. Irreversible chemical stratification is consistent with these results; plausible temperature variations in the deep mantle cause density variations that are smaller than the probable density contrasts across chemical interfaces created by
accretional differentiation and magmatic processes. Deep-mantle features may be convectively isolated from upper-mantle processes. Plate tectonics and surface geochemical cycles appear to be entirely restricted to the upper ~1,000 km. The 650-km discontinuity is mainly an isochemical phase change but major-element chemical boundaries may occur at other depths. Recycling
laminates the upper mantle and also makes it statistically heterogeneous, in agreement with high-frequency scattering studies. In contrast to standard geochemical models and recent modifications, the deeper layers need not be accessible to surface volcanoes. There is no conflict
between geophysical and geochemical data, but a physical basis for standard geochemical and geodynamic mantle models, including the two-layer and whole-mantle versions, and qualitative tomographic interpretations has been lacking
Inelastic tunnel diodes
Power is extracted from plasmons, photons, or other guided electromagnetic waves at infrared to midultraviolet frequencies by inelastic tunneling in metal-insulator-semiconductor-metal diodes. Inelastic tunneling produces power by absorbing plasmons to pump electrons to higher potential. Specifically, an electron from a semiconductor layer absorbs a plasmon and simultaneously tunnels across an insulator into metal layer which is at higher potential. The diode voltage determines the fraction of energy extracted from the plasmons; any excess is lost to heat
