letsencrypt

Already since couple of days, you (hopefully) enjoy my web site via HTTPS instead of HTTP.

Thanks to the letsencrypt.org initiative, which started it’s public beta yesterday, it is now quite easy and in fact free to get a backed server certificate. So, enjoy the fact that your passwords are a bit more secure now ;)

… my first ever public note on outreach :)
Building Blocks of the Universe – using stackable plastic bricks to impart knowledge in particle physics

ATL-OREACH-PUB-2015-001Abstract: This article presents possibilities to impart knowledge of and enthusiasm for particle physics to essentially all non-expert target audiences by the use of LEGO bricks and models of particle physics experiments built from these. Methods of using LEGO models, both as a passive exhibit and as part of interactive outreach events, are presented, along with a historical review of the “Build Your Own Particle Detector” programme and the corresponding idea of hosting competitions in building detector models in LEGO pieces as a perfect setting to grasp people’s attention, get them involved and ultimately convey knowledge in particle physics to them.
