Dustin Lang on big data from a big universe | Conversations at the Perimeter

- Dustin Lang is a computational scientist at Perimeter Institute who develops techniques for finding needles in the cosmic haystack. He works on several large sky survey projects, tackling the statistical data analysis required to discern meaningful insights from huge datasets gathered by telescopes.
In this conversation with Lauren and Colin, he shares his experiences mapping galaxies with the Dark Energy Spectroscopic Instrument (DESI), and hunting for mysterious fast radio bursts (FRBs) with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). He explains how he and his colleagues employ software solutions to expand capabilities of hardware telescopes, the challenges he has encountered in radio versus optical astronomy, and the important role of chicken wire at CHIME.

Conversations at the Perimeter is co-hosted by Perimeter Teaching Faculty member Lauren Hayward and journalist-turned-science communicator Colin Hunter. In each episode, they chat with a guest scientist about their research, the challenges they encounter, and the drive that keeps them searching for answers.
The podcast is produced by the Perimeter Institute for Theoretical Physics, a not-for-profit, charitable organization supported by a unique public-private model, including the Governments of Ontario and Canada.

Thank you! Please make more conversations.
Very interesting and informative. thanks for sharing.
Dustin Lang is a genius. Thank you, Dustin, for your great work!
Great discussion. What an exciting time for astronomy. I wasn’t expecting a story of something being done meticulously by hand when it comes to advanced tech lol. I’d imagine the depths of space would be scary for many. But, the joy of this discussion eases such fears. Instead, wonder, excitement, motivation and simplicity take ahold. Especially since computers are closer to the average persons life. The growing intersection of computer science and astronomy could prove vital in career paths and conversation starting.
Thanks for a great talk - Dustin explains things in a really interesting, clear way :)
Great program, very informative-along with quantum computing these areas of knowledge HAVE TO e🌌
I was wonddering how the new spectrograph worked on DESI , Thank you super interesting. I wonder what size those 10,000 motors are
They're tiny! Just 4 millimeters across! They are made by a Japanese company, Nashiki Precision Jewel Co (now renamed to Orbray), and are also used in medical application like endoscopic surgery!
@@dstndstn Super Cool. Thank you so much for your insights and for all the hard work you do. It pains me that there are so few people in the world actually using their brains but it brings me great comfort to know that amazing people like you are working on the most complicated questions we have ever tried to imagine.
Thank you and best of luck with your research
Mr Lang, could you write a book so that amateurs can get involved with the data please?
"Not an easy way to live!" Cool
I feel that old fotons degenerate, Red Shift îs not about velocity only but also about The history of this fotons. The Time component of 4d events create distorsions, so what is observed must be calibrate. Perpetuate wrong theoretical calibrations, make all complicate.
