James Hartle

Brief recollections by the author about how his work with Kip Thorne influenced his career in physics.

W. Luis Mochán

A brief dialogue about quantum entanglement (in Spanish).

Wolfgang Bietenholz

We describe the very nature of the elementary particles, which our (visible) Universe consists of. We point out that they are not point-like, and we depict their ways of interacting. We also address puzzles that occur even in the absence of particles, in the vacuum.

Abraham Loeb

A civilization in the habitable zone of a dwarf star might find it challenging to escape into interstellar space using chemical propulsion.

Manuel Ortega-Rodríguez, Hugo Solís-Sánchez

We tackle the question of whether there is a relationship between Stephen Hawking's disability and his ideas on the physics of black holes. The issue is relevant as it underscores the importance of diversity perspective in science.

Bob J. Scurlock

In this paper, principles of the CRASH3 damage-based collision algorithm are generalized for 3-dimensional motor vehicle crush profiles.

Seth Lloyd

This paper provides a quantum-mechanical analysis of an artwork, `Wigner's friends,' by Diemut Strebe. The work consists of two telescopes, one on earth, one launched into space, and explores ideas of quantum correlations and quantum measurement. This paper examines the scientific basis of the work and analyzes the form of quantum correlation between the two telescope systems.

E. Antonello

Following previous works on ancient myths in Greek and Latin literature regarding Ursa Major, and the possible relation with the ancient shape of the constellation, we discuss further this case in the light of the evolution of Homo sapiens and the ethnographic records of populations of Eurasia and North America.

Mordehai Milgrom

Translation of a popular article on MOND vs. dark matter that appeared, in Hebrew, in the Israeli magazine "Odyssea", dedicated to "thoughts and ideas in the forefront of science and philosophy".

Sabine Hossenfelder

It is argued that it is possible to give operational meaning to free will and the process of making a choice without employing metaphysics.

Robert D. Grober

This paper extends an initial study [arXiv:0903.1762v1] where it was shown the tempo of the putting strokes of accomplished golfers can be explained by assuming these golfers drive their biomechanical system (i.e. golfer and putter) resonantly. In this paper it is proposed that a reason for driving the system resonantly is to simplify the problem of distance control in putting.

Antonio Petraglia, Valerio Nardone

Here we propose two methods to get electroluminescence images from photovoltaic cells in a school or home lab.

M M J French

In this brief article I describe an experiment to illustrate how a fuse works. I have used this as part of lessons for my year 11 classes to demonstrate how an electrical fuse 'blows' when too high a current passes through it.

Vinod K. Mishra

This short monograph is devoted to different historical calendars prevalent in India from ancient times. They are classified and described with astronomical and historical details. Relationship of the calendrical elements to modern astronomical terminology has been explained. A proposal is outlined for modifying the calendar for removing inconsistencies and improving its accuracy.

Luigi Foschini

By using the Fermi satellite, a group of physicists discovers a new type of gamma-ray active nucleus

Lawrence M. Krauss

This comment was solicited by Physics in Canada and will appear alongside the article by Richard Mackenzie [arXiv:0807.3670] in the next issue.

Richard MacKenzie

In this article, inspired by Lawrence Krauss' plenary talk at the 2007 CAP congress, the relation between faith and science is examined.

Gerardo Adesso

This brief article discusses some aspects of quantum theory and their impact on popular culture. The basic features of quantum entanglement between two or more parties are introduced in a language suitable for a general audience, and metaphorically connected to love and faithfulness in human relationships.

Milan Batista

In the paper the linear force model used in car accident simulation programs is discussed. A model of restitution is proposed and the possible interpretation of CRASH coefficients is also discussed.

Jean-Pierre Luminet

Conventional thinking says the universe is infinite. But it could be finite and relatively small, merely giving the illusion of a greater one, like a hall of mirrors. Recent astronomical measurements add support to a finite space with a dodecahedral topology.
