COSMOS second season is announced. The new season is named as "COSMOS: Possible Worlds", will again delve into the cosmic revolution, profound scientific concepts and how we found our coordinates in space and time.

Here is the teaser video, enjoy!



Neil deGrasse Tyson also tweeted about the "COSMOS: Possible Worlds"

NASA's James Webb Space Telescope is a civilization scale mission, set to look back to the first galaxies formed after the Big Bang and help answer the question "are we alone in the universe?" After passing a key test at Johnson Space Center designed to simulate the cold vacuum of space, Webb is ready for the next step ahead of a launch in 2019.

By combining the visible and infrared capabilities of the Hubble and Spitzer space telescopes, astronomers and visualization specialists from NASA’s Universe of Learning program have created a spectacular, three-dimensional, fly-through movie of the magnificent Orion nebula, a nearby stellar nursery. Using actual scientific data along with Hollywood techniques, a team at the Space Telescope Science Institute in Baltimore, Maryland, and the Caltech/IPAC in Pasadena, California, has produced the best and most detailed multi-wavelength visualization yet of the Orion nebula.

Advancing Women in Science: An International Perspective.
Edited by Willie Pearson, Jr, Lisa M. Frehill, Connie L. McNeely

The collection of articles in this book presents a variety of approaches to what might be the reasons that there's a relative lack of women in certain fields of science. In addition it gives some insight about why even when women are quite well represented in the field, the scientific field itself might still be dominated at the highest reaches by men for a variety of reasons.

The focus of the articles is varied from attitudes, culture, education and many other sometimes even surprising aspects. Some of the articles are more general, whilst some present specific situations from different countries. I found those the most illuminating and very valuable because of the international reach.

Some of the issues that women who'd like to work in a STEM field might sound simpler and easier to solve than they really are. Depending on the culture it's not always easy or even acceptable for a woman to even study long enough to get a higher education, not to even mention striving for achievements in science or technology.

All in all the collection gives the impression that the reasons why women might not study science, mathematics or informatics as often as men are very different from country to country depending on the country's recent history, the cultural and religious background. While in some cases it might seem as if it is easy to point a finger at specific causes for lack of women in science, it is much more complex.

Some of the solutions and various policies that might improve and already have improved the situation are also presented. I found it fascinating, especially since improving women's participation in STEM fields would also help other minorities participation in those fields or at least show the way to it.

Superconductivity. An Introduction by Philippe Mangin , Rémi Kahn

In Mangin and Kahn's "Superconductivity" there is an overview of the scientist who are/were involved in the discoveries connected to superconductivity.

After the brief historical overview, the reader is presented with the London theory of superconductivity which gives an idea how current in and around superconductors is connected to the electromagnetic field. It is presented in such a way that you go step-by-step from the more general ideas to specific examples. I found the division between the topics and in the chapters very helpful and clear, as you can easily tell what you're reading about, where the specific equations are applicable in that way etc.
In addition to getting familiar with the London theory, the reader can also read about the non-local nature of superconductivity, which is an extension of the London theory.

What I found most interesting were the chapters on thermodynamics of particular types of superconductors. The different phase transitions and their orders are explained there as well.
It's important to note that chapters are followed by appendices that are helpful for understanding the electromagnetic features of the systems described or provide solutions to specific cases.

In "Superconductivity" you can also read about how SQUID magnetometers work, that enable scientists to measure very small magnetic fields.

The book is a well-rounded, complete and student friendly guide to superconductivity. It assumes that the reader is well acquainted with at least undergraduate physics.

Theoretical Physics 1: Classical Mechanics by Wolfgang Nolting

Theoretical Physics 1 starts with providing the student with the necessary mathematical apparatus that will be needed to understand classical mechanics. It starts from differential calculus and integration and continues with operations with vectors.

After a crash-course of calculus and algebra the book continues with mechanics starting from the usual – coordinate systems, uniform motion, circular motion, forces etc. It is interesting to note, that in this book there are lots of examples of connections between classical mechanics and other areas of physics, which bring out similarities between the different laws of physics. As an example – different central forces as exemplified by both Gravitational force and Coulomb force but also the force affecting an isotropic harmonic oscillator.


One of the features I liked best about this book is that the same concepts come up in several places and they’re explained more thoroughly in one place, but they’re mentioned briefly in another so that when you get to the longer discussion of the topic you already have a clue about what the main point is. That is one of the features which gives some more incentive to keep on working through the theory, test your understanding on the exercises and self-examination questions. In the end the reader is quite likely to feel that they’ve learnt something. Because of its clear presentation of the topics, different levels of exercises with solutions provided in the back of the book, it's an ideal book for independent study.
