Motivated by the idea that high-quality graphene always produces innovative aspects of physics. In this outline, a novel class of two-dimensional (2D) assembly namely thickness controlled homo-junctions with a configuration similar to graphene-insulator-graphene is introduced in this work. We demonstrate 2D-2D quantum tunneling between two graphene stacks in which van der Waals gap serves the purpose of tunneling barrier. The nonlinear I-V characteristics with improved current switching ratio (I on / I off) of ~106 coupled with counterclockwise current hysteresis which are the signatures of a memristive devices has been validated in the tunneling regime. It is the first time to report on revealing thickness modulated 2D homo junctions in exfoliated graphenic material and to disclose the involved tunneling mechanism for switching applications. This work promises well for the possibilities of graphene sheets for the realization of two terminal configured devices as a substitute of three terminal graphene based field effect transistors in the area of resistive switching memories. As graphene being a versatile candidate possessing durable future in nano-electronics, therefore understanding deep insights of its charge carrier transport mechanism under range of bias voltages is prerequisite. Strikingly, an unconventional approach for improving on/off ratio of graphene based resistive switching devices has been put forward in the present report.

The rapidly growing department-wide network comprises about 500 computers. These include about 200 workstations from Sun, HP, and SGI, and about 300 PCs, all connected to a 100 Mbit/s network with multiple parallel T3 lines running to individual research laboratories and computer rooms. The server functions are performed by several high-speed, high-capacity RAID servers from Network Appliance and IBM which serve user directories and software applications in a unified transparent fashion. All this computing power is distributed in research laboratories, computer classrooms, and open-access computer rooms.

The Electromagnetics Laboratories involve the disciplines of microwaves, millimeter waves, wireless electronics, and electromechanics.

The 1st section lays the groundwork for the rest of the book and starts with an exploration of the importance of physical intuition and paradigm shifts in physics understanding, together with an overview of the 'birth' of quantum physics and relativity. This section gives a very interesting perspective on the role of intuition in understanding physics. The 1st chapter illustrates the difference between mathematical logic and physical intuition very well, using examples from the historical development of relativity, and stresses the importance of emphasis on conceptual models and relations to prior knowledge. The other chapters of this section primarily emphasize knowledge of historical developments in science, but also demonstrate how scientists combine mathematics and physical intuition in the development of new theories.

The book ends in section 3 with several examples of educational projects in Norway, Germany, Australia, Scotland, the Netherlands, the Czech Republic and South Korea. This section stresses the importance of this book, since it shows that the implementation of Einsteinian physics is currently ongoing. The provided examples give insight into design aspects that are important for introducing Einsteinian physics, and also demonstrate that Einsteinian physics has already been successfully implemented at the secondary level.

From my perspective as a teacher and teacher educator, this book offers a large collection of ideas and examples for teaching Einsteinian physics. Even though this book will not give complete lesson plans that can be directly used, it is a source of inspiration with background information on different approaches, useful references for further exploration, and examples of classroom activities that can be used in classrooms.

Nordell maintains that stereotyping leading to bias begins with children who perhaps are addressed in school as 'boys and girls'. While categorisation is necessary in many aspects of daily life, it is essential to monitor the ways in which this can lead to bias. She describes in detail a Swedish pre-school initiative which led to less stereotyping. Discrimination on the base of gender, class, sexuality, race, and ethnicity were all avoided. In Swedish there is a gender-neutral pronoun 'hen' and groups of children are often addressed as 'friends'.

By any measure, this is an unusual book written by a remarkable author. Chanda Prescod-Weinstein is a faculty member both in physics and in women's and gender studies at the University of New Hampshire, a rare combination indeed. She describes herself as 'a working-class Black queer femme'; she is also a Jew and has a disability. The title is the same as that of a blog by the same author, who is also a regular contributor to journals such as New Scientist and Physics World.

The book is split into four phases, each comprising a few chapters around an overarching theme. Phase 1 is mainly to do with physics and the author's passion for theoretical particle physics, which shines through. We are whizzed through some of the big questions of physics: in a little under 50 pages, we have the Standard Model, string theory, special and general relativity, quantum gravity and dark matter. This phase is useful for setting the scene, and a few topics are used later as analogies for social contexts, but it is too dense to be useful as an introduction to the topics for a novice. Further, the level is uneven: although the reader is expected to know what a gravitational well is, there is a lengthy explanation of how rainbows are formed.

The professional juxtaposition of physics and gender studies, with its roots in Critical Theory, is what gives the book its unique flavour. This is a political and personal book with a science perspective, with rather more of it concerned with the scientific establishment and the author's experience of it than with the science itself. It is also focused heavily on the United States, with almost no reference to anywhere else, not even the developing world, which is a regrettable omission. There is much on disparity in the US but little about global inequality. She questions US science spending priorities but never addresses questions such as whether particle-physics theory, say, should be funded when so many people are starving.

Undoubtedly, this is a unique and very important book that raises many uncomfortable issues about society at large and science's role in it. UK readers will perhaps find the US emphasis parochial and the Critical Theory approach, with its associated jargon, will alienate and irritate many physicists. Maybe that it the intention. But physicists would benefit from the challenge of hearing what she has to say, although they might well be frustrated by the negativity. I doubt if many school students would find the book interesting from a physics perspective although any interested in the politics of gender and race might be stimulated.

As a final remark, I am acutely aware that I am a white, male physicist, albeit with a disability and from a working-class background. I am obliged to be honest in considering the book, but I am aware I may well be part of the problem. 17dc91bb1f
