A Little Behind, and a Little Ahead

Still playing catch up – but, we had our first colloquium presentation of the spring, and one more coming up!

“Learning about the Universe with Data Science”

Dr. Viviana Acquavivia (CUNY CityTech)

A galaxy’s Spectral Energy Distribution (SED) is a chart of the brightness of a galaxy as a function of wavelength. It contains information about, for example, the galaxy’s stellar population age, stellar mass, distance from Earth, and star formation history. In the last decade, large galaxy surveys have provided us with an unprecedented volume of data for many galaxies billions of light years away, and it has become increasingly crucial to improve the tools we use to extract information from these data. I will present two examples of how supervised machine learning algorithms can be used to learn about the Universe’s history. In the first one, we show how we can discriminate between nearby and faraway galaxies in order to improve our knowledge of dark energy, the mysterious source of the present accelerated expansion of the Universe. In the second, we attempt to recover the history of metal enrichment (the production and dissemination of elements heavier than helium, which astronomers improperly call “metals”) through cosmic time.

“Extreme NYC Weather: Connecting the Ground-Station Events to the Large Scale Storms’”

Dr. James Booth (CUNY City College)

New York City and the Northeastern United States are subjected to multiple types of weather hazards. These events range from windstorms to flooding to heat waves. From an atmospheric science prospective, an important question is: what are the synoptic-scale weather features responsible for these events and have they changed over the recent past? In this talk, I will address these questions for three specific types of extremes: (1) wintertime windstorms, (2) storm surge, and (3) inland precipitation. For this analysis the strongest events are identified in weather station records using Extreme Value Theory. Then, using the existing physical understanding of the storms, we associate the extreme events with extratropical and/or tropical cyclones. The life cycles and track locations of these storms are analyzed, and these will be discussed in the context of the recent snowstorm, Jonas. Additionally, the work creates probabilistic estimates of the most common pathways for the storms that cause the different hazards.

General Note: We’re proud to have this year’s events sponsored by the ESC STEM Club. Please join us after each talk for an informal Q&A with food. (Did I mention that there will be free food?)

We’re All Going to Die? Or not?: Ecopsychoanalysis and Climate Change

In preparation for Earth Day next week, Dr. Joseph Dodds from the University of New York in Prague will deliver the next Science Colloquium seminar. He will present his talk on, ‘Feeling the Heat… What is Ecopsychoanalysis?: Psychoanalysis and Climate Change in the Three Ecologies‘.

When: Tuesday, April 14th
Where: 325 Hudson St., NY, NY; Hudson Gallery (Room 544)
Time: 5-6PM

Following the seminar, we will also have a reception with appetizers and light refreshments. Please join us for both the talk, and an informal chat during the reception with Dr. Dodds.

To Flatter or Not To Flatter?

Dr. Claudia Brumbaugh (CUNY Queens College) will present her seminar entitled, ‘Attraction Preferences: Where does Attachment Security Rank’ for the next Science Colloquium. Aside from seeing her volunteer for the Sunday NYC Audubon Ecocruises, it’ll be great to learn about her research on the evolution of human attraction.

Bats!

It’s just been a long, long time since I last posted. So much to tell…

But, first – Dr. Paul Velazco from the American Museum of Natural History will present his seminar ‘Historical Diversification in the Neotropics: Evolution and Variation of Noctilionoid bats’.

Five Boro Bike Tour

Yesterday, I did the TD Five Boro Bike Tour again. As I said to my wife the night before, I often feel lucky to participate in this bike tour, and there’s simply something magical about the opportunity to ride your bike through the streets of NYC, the FDR, uncontested over the Queenborough Bridge, and my favorite, the gauntlet of the BQE. However, I only wish that I actually cycled anytime during the preceding year. Aside from a brutally cold winter, I scaled back my riding time to being a daddy. This is a trade-off I’d never give up, except that I feel like I was hit by a truck, as my entire body hurts. But, I did it, and I’ll do it again next year.

Couple of side notes: 1) Thanks for the mechanic team on Church and Reade streets at the beginning of the tour. My chain (albeit rusted to the core) unhinged itself on the subway, and they were able to realign it about 5 minutes before our group started. 2) I also pulled a cramp on both legs going up the Pulaski Bridge, and a second momentary panic – thinking the tour was over for me right there.

My chariot (and the little car that took her to the tour). I especially like the add-ons to the frame. I lost my water bottle and holder, as both snapped off on last year's during as I approached the Pulaski Bridge. Speaking of Pulaski, I suspect there's a superstition about to become enshrined about that spot.

Superfans!

Something less academic… on April 12th, my little group of superfriends were unashamedly superfans, as we attended a solo performance by Glen Phillips in Bay Shore. Aside from my typical music preference, albeit becoming more eclectic as I age, there were two styles that resonated since my young: one which is clearly evident, and the other less so. For the latter, it managed to evolve from a little group from Santa Barbara to a maturity in lyric and song. Enjoy!

As Gandalf said to Pippin upon their first meeting with Denethor, my wife often reminds me of the same when is comes to those I admire, 'Listen carefully: Lord Denethor is Boromir's father. To give him news of his beloved son's death would be most unwise. And do not mention about Frodo or the Ring. And say nothing of Aragorn either. In fact, it's better if you don't speak at all.'
