Dear all,

since I am not anymore in the field of fusion research, I does not make anymore sense for me to moderate and organize this community.
I wanted to now whether some of you would be interested to take it over.
I will consider only people working in this field of research.

And with a huge of publications... No I am kidding for this last one. The interest to share with a wide audience will be enough.

Ein Beispiel von Gentrifizierung in München

_ German only and very Munich-centered issue _

Seit 10 Jahre wurde in München Haidhausen, in der Wörthstraße ein wertvoller Beitrag geleistet die Kunst des klassischen Balletttanzes mit viel Liebe und Engagement, Kindern und Jugendlichen zu vermitteln. Durch die Übernahme der Räumlichkeiten eines Edelfahrradladens musste die Schule weichen. Die Elternschaft möchte die Ballettschule Haidhausen unterstützen, weiterhin die Arbeit in Haidhausen nachgehen zu können und somit nicht einen weiteren Teil des kulturellen Lebens in Haidhausen durch Gentrifizierung zu verlieren.

Wer kann dabei helfen, dieses Beispiel ans Licht zu bringen?

* How I stopped to worry about hardware *

I have already mentioned the RedPitaya, a kind of Raspberry Pi on steroids, with a double core, a FPGA and fast ADC/DAC to play in the MHz range.
I detail a bit more here why it is so interesting not only for educative purposes but also for practical applications, as a replacement for programmable logic controllers.

* The most difficult questions about space projects: Feasible or not ? *

I got many times this question in the last days: "As an ex space propulsion engineer, do you think that +SpaceX vision if feasible?".
My answer is: "I don't know".

Assessing the feasibility of concepts of space mission is difficult if you don't know how the concept will be executed. The organization, the tools count as much as the design which is, most of the time, classical.

* Searching a project partner: a taste of hell *

Some random and cathartic thoughts on the difficulties to find some motivated project partners. For a simple project.
I have even more respects for those who plan to build interplanetary spaceships.

* The art of science communication *

My attention was attracted by this article:
about the necessity to simplify scientific articles.

I was wondering what types of communications the scientists exactly have to do in their work. I have tried to distinguish the different groups and their characteristics.
It seems to me that the most difficult task is the communication with the public, especially at a time where scientists are more easily exposed and that the public is less and less attracted by facts, data and rational discourse than by emotion and kitties.

Augmented discussions

I have finished to write the prototype of a pluginfor JupyterLab: it is a chat! But in addition to text, you can write and run code as if you were in a Jupyter notebook. And the other participants to the chat can see your code and the output.

I had the idea at the lab where we are using Jupyter notebooks to process the data. And a clear missing tool was a way to communicate while working on our notebooks. I thought first to write a simple messaging plugin for Jupyter. But I realized that it would be even better if we could use Jupyter to discuss. So now, we can exchange words, algorithms and data!

The difference with a collaborative notebook is that each user has his own session and his own cells; so you can use the kernel and the language of your choice without disturbing the others.

This looks like an interesting beginning.

Following the excellent article by +Massimo Pigliucci and the insightful post by +Sabine Hossenfelder on the role of philosophy in physics, I wanted to write my opinion, as a modest physicist, on the topic. I do not have the talent of both but I hope I can convey some elements of my message.
Short summary for trolling: yes philosophy is useful for physics.

During Scipy2016, the Jupyter team announced the release in pre-alpha of the next generation notebook environment: JupyterLab. I had some time to use it in previous versions and here is my review of it. It is promising.
