Is Pokémon Evolution Dangerous?
This paper will look at the effect of Pokémon evolution using Einstein’s equation for mass-energy equivalence E = mc2. The energy required to create the mass gained by a Pokémon in evolution will be calculated and compared to some real world energy values for perspective. The specific examples amalysed in this paper are the evolution of Magikarp and the mega evolution of Rayquaza
Morphology in the Era of Large Surveys
The study of galaxies has changed dramatically over the past few decades with
the advent of large-scale astronomical surveys. These large collaborative
efforts have made available high-quality imaging and spectroscopy of hundreds
of thousands of systems, providing a body of observations which has
significantly enhanced our understanding not only of cosmology and large-scale
structure in the universe but also of the astrophysics of galaxy formation and
evolution. Throughout these changes, one thing that has remained constant is
the role of galaxy morphology as a clue to understanding galaxies. But
obtaining morphologies for large numbers of galaxies is challenging; this
topic, "Morphology in the era of large surveys", was the subject of a recent
discussion meeting at the Royal Astronomical Society, and this "Astronomy and
Geophysics" article is a report on that meeting.Comment: Meeting Report article published in the October 2013 issue of the

Galaxy Zoo: comparing the demographics of spiral arm number and a new method for correcting redshift bias
Citizen Science: Contributions to Astronomy Research
The contributions of everyday individuals to significant research has grown
dramatically beyond the early days of classical birdwatching and endeavors of
amateurs of the 19th century. Now people who are casually interested in science
can participate directly in research covering diverse scientific fields.
Regarding astronomy, volunteers, either as individuals or as networks of
people, are involved in a variety of types of studies. Citizen Science is
intuitive, engaging, yet necessarily robust in its adoption of sci-entific
principles and methods. Herein, we discuss Citizen Science, focusing on fully
participatory projects such as Zooniverse (by several of the au-thors CL, AS,
LF, SB), with mention of other programs. In particular, we make the case that
citizen science (CS) can be an important aspect of the scientific data analysis
pipelines provided to scientists by observatories.Comment: 12 pages, 2 figure
Galaxy Zoo: The large-scale spin statistics of spiral galaxies in the Sloan Digital Sky Survey
We re-examine the evidence for a violation of large-scale statistical
isotropy in the distribution of projected spin vectors of spiral galaxies. We
have a sample of spiral galaxies from the Sloan Digital Sky
Survey, with their line of sight spin direction confidently classified by
members of the public through the online project Galaxy Zoo. After establishing
and correcting for a certain level of bias in our handedness results we find
the winding sense of the galaxies to be consistent with statistical isotropy.
In particular we find no significant dipole signal, and thus no evidence for
overall preferred handedness of the Universe. We compare this result to those
of other authors and conclude that these may also be affected and explained by
a bias effect.Comment: Accepted for publication in MNRAS. 8 pages, 5 figure
