I'm on my way to fedisciences.org, to anticipate the future shootdown of astrodon.social. I will toot again once there.

Thanks @sebinthestars for running smoothly this server for the last 3 years or so. I am sorry it ended this way and no sustainable solution was find.

Hi everyone,

I just arrived from astrodon.social, where I've been tooting since about three years.

I’m an astrophysicist working in the field of gamma-ray astronomy at IRAP (@cnrs) in Toulouse, France. Since a couple of years I work on assessing and reducing the environmental impact of scientific research, and in this context I’m engaged in @labos1point5 and @a4e.
I’m also doing local politics as city and community ​​councillor with a strong focus on environmental politics.

To conclude:
a) travel by bicycle and train through Europe is possible,
b) it requires some preparations, though, and then some skills in managing risk,
c) it could be made a lot easier and more popular if European policymakers seriously wanted to decarbonize the transport sector.

I enjoyed the entire journey and ended up doing everything I wanted to do.

My main specific choices were,
- to accept (whether I like it or not) that the smartphone is an essential tool (but you need a power bank along with it),
- to buy an interrail ticket (4 days in a month), this may or may not have been the cheapest option, but it provides some flexibility,
- to navigate google-free, that is with OsmAnd~ (the free version, from https://f-droid.org/en/packages/net.osmand.plus/),
- to sleep, when needed, in youth hostels (interesting places, good value for money),
- to make sure the bicycle is not too heavy (ruling out any e-bike).

Thanks for following so far - will try to answer any questions that might come up (and I have some more projects like this next month).

@boitarsor @ffeth Oui, ca montre bien que c'est possible quand on a une volonté politique forte... pas comme à Marseille (qui part cela dit de très très loin).

C'est pareil à Bordeaux : capitale du bouchon en voiture dans les années 90', les travaux du tram ont tellement emm*&%#@er les voitures, qu'aujourd'hui, beaucoup sont à vélo.

J’ai encore failli me faire renverser par un cretin #marseillais (pléonasme ?) qui ne voulait pas me laisser passer en #velo, lui était en #camion !👹

Il ne voulait pas perdre 2s au risque de prendre 20 ans aux baumettes !

I think some conference organizers are desperate to find invited speakers.

That is still better than my recent invitation to a conference on petrochemical engineering… 🙄

#academicchatter #AcademicLife

Un groupe de lycéen•nes de Carpentras parodie la série #bref pour présenter leur projet #scientifique porté par ma collègue Sophia Sulis @LAM_Marseille. Ils ont observé un transit d’#exoplanete depuis l’#observatoire de #HauteProvence pour la mission spatiale #Ariel de l’#ESA.

A voir absolument!
