Tweet Beat: 22 August Round-up
It’s impossible to see everything that happens at the conference each day. Thankfully, we can turn to the conference hashtag, #IAU2018, to get insights from other delegates on the best of the rest.
The best tweet of the day was about Sarah Sweet’s talk, which was presented via a pre-recorded video:
Sarah Sweet gives a great talk by video at the IAU Focus Meeting 6 on angular momentum in galaxies. She couldn’t travel to Vienna because “like some galaxies, I have a large bulge to total mass ratio”! #IAU2018 #IAUFM6 pic.twitter.com/AiB4QuCsKo

In a bit of perfect timing, she added a new Earthling to our planet’s population earlier in the day!
Wednesday’s plenary by Manuel Güdel got everyone talking:

Güdel: There is a long, complicated process to go from molecular clouds to planets. These planets then have to acquire/keep water, maintain an atmosphere, survive planetary system dynamics and stellar flares, and then biology has to happen! tl;dr habitability is hard #IAU2018 pic.twitter.com/CybvwCduya

Wow. Mind blown by Manuel Güdel's talk at #IAU2018 on the number of conditions and processes that must go exactly right to end up with a habitable Earth-like planet. It looks so improbable that I don't even believe Earth exists anymore.

Meanwhile, the sessions were full of new ideas — and, occasionally, some old-school methods, too:
Filippo Fraternali being 'old fashioned' (his words, not mine!) using analytic calculations rather than simulations to create a structural evolution model of galaxy disks. Gas accreting onto the MW could be rotating 70-80% slower than the disk#IAU2018 pic.twitter.com/xpE2xEtGkM

People were getting a bit concerned about the gender ratio of speakers in sessions:
There has been some good stuff in IAU345 "Origins…" today, but a disturbing lack of women speakers – 0/10 #IAU2018

Wondering about the Gender ratio of speakers at #IAU2018. I have the impression that is highly dominated by males.

The Invited Discourse by Marica Branchesi was so popular that people were sitting on the floors and lining the walls:
Easily 60 people standing/sitting on the floor. #iau2018

Wednesday wasn’t without its cute factor:
Matthew Taylor discusses the dwarf galaxy satellite system of Centaurus A. But first an admission: he’s really more of a globular cluster guy, the possum to our group of cats. His metaphor, not mine! #iau2018dwarfsforever #iau2018 pic.twitter.com/8xAr8biknH

It was also the first day of waltz lessons. The next is 12:45-13:15 on 28 August in Room L2, followed by an opportunity to dance during the handover ceremony on 30 August.
