CfA Colloquia
Our weekly (during the academic year) colloquia are now available to
the public at https://www.youtube.com/channel/UCAp...xmiV95A0ChueYg This week's by Daniel Eisenstein was particularly good. https://www.youtube.com/watch?v=429MRyF7PyA The topic was measuring cosmological parameters using Baryon Acoustic Oscillations, but he gives quite a bit of background on other cosmological measurements. Make sure you view at least the 480p version and preferably the 720p; otherwise you won't be able to make out details of the graphics. -- Help keep our newsgroup healthy; please don't feed the trolls.

In general, I think this is a great idea. Of course, people who have trouble listening to a talk a week at their own institute might find it difficult to see even more talks on the web, but on the other hand they can hear talks they perhaps otherwise wouldn't hear, replay bits they don't understand etc. However, sometimes people mention things in a talk which they wouldn't like to mention in a more public forum. They do want to mention them, though, in order to get feedback etc. Do you think the fact that the talks are on YouTube will influence this aspect of the presentations? Presumably the speakers are asked, or at least informed. Have all agreed? Will portions of the talk be removed so that the things mentioned above can appear in the talk but not in the public version of it? I'll have a look when I have time. I think questions and answers should be included as well. (Anyone who edits conference proceedings should get the questions and answers included as well. This is what makes conference proceedings still interesting even after several years.) |

Phillip Helbig---undress to reply writes: Presumably the speakers are asked Speakers are asked in advance. And I asked before making the public posting. Until recently, the live webcasts and recordings were only available internally at CfA, but that has now changed. Have all agreed? I don't know of any refusals but can't swear there haven't been any. Will portions of the talk be removed I don't know of any editing; given staff limitations I'd find it surprising. The initial webcasts are live, and I don't see how they could be edited. I think questions and answers should be included They are, but it is sometimes hard to hear the questions, depending on how far from the microphone the questioner is and how loudly the question is asked. -- Help keep our newsgroup healthy; please don't feed the trolls.
