Objective: To explain how the philosophy of nutrition is part of the philosophy of health. To show that this link allows practical solutions for equity and sustainability.Method: An analysis of the historical philosophies concerned with nutrition and health. A comparison of the definitions in the history of mind from antiquity to the beginning of the twenty-first century.Conclusion: We are not individually healthy, but we are so in togetherness, even with animals and plants. Comprehensive nutrition science has physical, social and environmental attributes. It follows that nutrition is good for the enhancement of good company with human beings as well as with the connatural world. We recognise that we owe to others what we are and this constitutes the equity of being. [ABSTRACT FROM AUTHOR]

Explores the cultural and conceptual history of nature in the Western tradition and the reasons and chance for a shift toward a philosophy of nature centered in nature. Alexander von Humboldt's perception of humanity as a living natural whole; Perception of nature in poetry and visual arts; Sir Francis Bacon's idea of political order in science and nature.

The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km. Autonomous controls that lock the laser frequency to a cavity reference and establish the 5 degrees of freedom two-way laser link between remote spacecraft succeeded on the first attempt. Active beam pointing based on differential wave front sensing compensates spacecraft attitude fluctuations. The LRI has operated continuously without breaks in phase tracking for more than 50 days, and has shown biased range measurements similar to the primary ranging instrument based on microwaves, but with much less noise at a level of 1 nm/√Hz at Fourier frequencies above 100 mHz.

High precision temperature measurements are a transversal need in a wide area of physical experiments. Space-borne gravitational wave detectors are a particularly challenging case, requiring both high precision and high stability in temperature measurement. In this contribution, we present a design able to reach 1 μ K / Hz in most of the measuring band down to 1 mHz, and reaching 20 μ K / Hz at 0.1 mHz. The scheme is based on resistive sensors in a Wheatstone bridge configuration which is AC modulated to minimize the 1/f noise. As a part of our study, we include the design of a test bench able to guarantee the high stability environment required for measurements. We show experimental results characterising both the test bench and the read-out, and discuss potential noise sources that may limit our measurement. [ABSTRACT FROM AUTHOR]
