Vienna, 2013-12-18 -- we had a room in Cafe Votiv, and Axel explained to us quantum physics. He is very good at this; he understands physics, and as a rationalist he does not add the typical nonsense that usually comes with this topic. We even had some experiments with a laser pointer (I didn't know previously you could do quantum experiments just like this; outside of the lab). -- He definitely should do a YouTube video on this topic.
Bratislava, 2013-12-20 -- we had a presentation on social system, orphanages, adoptions, and professional families; by a former Member of Parliament. We discussed some ideas on altruism afterwards.
If you had an interesting Less Wrong meetup recently, but don't have the time to write up a big report to post to Discussion, feel free to write a comment here. Even if it's just a couple lines about what you did and how people felt about it, it might encourage some people to attend meetups or start meetups in their area.
If you have the time, you can also describe what types of exercises you did, what worked and what didn't. This could help inspire meetups to try new things and improve themselves in various ways.
If you're inspired by what's posted below and want to organize a meetup, check out this page for some resources to get started! You can also check FrankAdamek's weekly post on meetups for the week.
Tell us about your meetup!
