Hello, I was thinking about math or science related meet ups. Sort of like the website meetup where strangers with common interests who previously didn't know each other meet and pursue those activities. Are there such things for people to do recreational math science or engineering? Or is this only in the domain of academia. This website is a substitute, but of course you have the lag time between responses, and it's not in person. Has anyone heard of or done something like this? I sometimes think the society wouldn't have enough people in an area with an interest to do something like this.
