Blueberry Earth

  journal={Physics World},
This paper explores the physics of the what-if question "what if the entire Earth was instantaneously replaced with an equal volume of closely packed, but uncompressed blueberries?" While the assumption may be absurd, the consequences can be explored rigorously using elementary physics. The result is not entirely dissimilar to a small ocean-world exoplanet. 
How much value can our decisions create? We argue that unless our current understanding of physics is wrong in fairly fundamental ways, there exists an upper limit of value relevant to our decisions.
Analogues of mental simulation and imagination in deep learning
Model-based methods in deep learning can serve as powerful tools for building and scaling cognitive models and matching the capacity of human mental simulation for efficiency, compositionality, generalization, and creativity.


A new family of planets? Ocean-Planets
A new family of planets is considered which is in between the rocky terrestrial planets and the gaseous giants, “Ocean-Planets.” We present the possible formation, composition and internal structure
Volatile-rich Earth-Mass Planets in the Habitable Zone
A small planet is not necessarily a terrestrial planet. Planets that form beyond the snow line with too little mass to seed rapid gas accretion (10 M⊕) should be rich in volatile ices like H2O and
Solar System Dynamics
The Solar System is a complex and fascinating dynamical system. This is the first textbook to describe comprehensively the dynamical features of the Solar System and to provide students with all the
A phase diagram for jammed matter
This work presents a statistical description of jammed states in which random close packing can be interpreted as the ground state of the ensemble of jammed matter and demonstrates that random packings of hard spheres in three dimensions cannot exceed a density limit of ∼63.4 per cent.
A Miniature Instrumented Sphere to Understand Impacts Created by Mechanical Blueberry Harvesters
The majority of U.S. northern highbush blueberry (Vaccinium corymbosum) and southern highbush blueberry (V. corymbosum hybrids) for the fresh market is hand harvested because of the high bruising
Chemical composition of selected cultivars of highbush blueberry fruit (Vaccinium corymbosum L.)
The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near
Sensory and textural evaluation of Maine wild blueberries for the fresh pack market
Maine wild blueberries were sized according to berry diameter into three size classes; ≤ 8 mm, 9–10 mm and 11–12 mm. A consumer sensory panel was asked to indicate their opinion of flavor, texture
Shelf Life Determination of Fresh Blueberries (Vaccinium corymbosum) Stored under Controlled Atmosphere and Ozone
Blueberries stored under O3 atmosphere showed reduced weight loss at 12°C by day 10 and loss of firmness when compared to the other treatments, suggesting low concentrations of ozone gas together with proper refrigeration temperature can help protect fresh blueberries quality during storage.
Physical properties of acerola and blueberry pulps
Abstract In this work, some physical properties of acerola and blueberry pulps were determined. The density was determined by the pycnometer method; the electrical conductivity using a
Effect of drying method on drying time and physico-chemical properties of dried rabbiteye blueberries
Abstract Individually quick frozen (IQF) rabbiteye blueberry cultivars Brightwell and Powderblue were dried in an air-impingement dryer at 85 °C and 107 °C using two different configurations. The
