A Sense of Doubt blog post #1765 - New galaxies found missing dark matter

So, now what are we going to do with all of our theories?

"There is more in heaven and earth than is dreamt of in your philosophy, Horatio."

The more we think we know, new discoveries will prove there is still much that we do not know.

Astronomers Find 19 More Galaxies Missing Their Dark Matter (astronomy.com)

Posted by BeauHD on Saturday December 14, 2019 @02:00AM from the missing-piece-of-the-puzzle dept.

Iwastheone shares a report from Astronomy.com:Astronomers have discovered 19 more galaxies missing their dark matter. Instead of dark matter, these strange galaxies are mainly filled with regular matter, like the protons, neutrons, and electrons that make up everything we're familiar with. The new find, published November 26 in Nature Astronomy, bolsters the controversial recent discovery of two other galaxies without dark matter. The mysterious substance accounts for most matter in the universe, and it's thought to be the primary component of all galaxies -- as well as the main driver of galaxy formation in the first place. So, finding so many galaxies without the exotic matter suggests astronomers are missing something major about how galaxies form and evolve.

"This result is very hard to explain using the standard galaxy formation model," said lead author Qi Guo of the Chinese Academy of Science in a press release, "and thus encourages people to revisit the nature of dark matter." The latest batch of galaxies missing dark matter was discovered when Guo and her team explored the nature of 324 dwarf galaxies using data from the Arecibo Observatory in Puerto Rico and the Sloan Digital Sky Survey. With this data, they followed in the footsteps of Rubin and Ford, studying how fast hydrogen gas rotates around each galaxy. They also calculated how much normal matter -- in the form of both gas and stars -- they contained. After crunching the numbers, Guo and her colleagues determined that, of the 324 dwarf galaxies they investigated, 19 of them contain enough visible matter to solely explain the motions of the galaxies' hydrogen. In other words, a lot of dark matter seems to be missing from these galaxies.

A Sense of Doubt blog post #1764 - Grading Robot Powers Down

A Sense of Doubt blog post #1764 - Grading Robot Powers Down

Though I am posting this blog entry almost an entire week late, after about a week of almost total inactivity because of how hard I worked to meet all these deadlines, it was this day, Tuesday December 17th that was the last day of my grading period for Fall semesters in 2019.

I had one grade deadline yesterday, Monday December 16th at 14:00 hours that I missed by three minutes. I was in the system loading the final grades when the deadline struck, and so I managed to get the grades done and was not kicked out.

I call this work being "grading robot." It was a term I invented myself, but then I decided to run a Google search to see if anyone else had coined the term, used the term, or created memes, like the one I found shared below.

I love that the article I found was posted on a blog that looks cool and I wish was current: SCHOOL OF DOUBT, which is a title that readers of this blog should recognize as very close to my own SENSE OF DOUBT.

In any case, me, Grading Robot, has machine-powered through six classes worth of grades meeting three deadlines in two days. I had two more today at 17:00 and midnight.

But what if I had an actual robot that did the grading?

This seems even more ideal than imagining that I am a robot.

And so, I am done with grading for the year. But I do not yet own a robot.

https://schoolofdoubt.com/2013/04/06/where-do-i-get-one-of-these-fancy-essay-grading-programs/

According to The New York Times, I might be able to reclaim my weekends soon: New Test for Computers: Grading Essays at College Level.

My initial gut reaction? Bring. It. On.

I hate grading essays. I hate just almost every single thing about it. The liberal arts college where I teach is small and teaching focused, so we don’t get the two courses per term that research profs get; we teach four classes every term. My load usually looks exactly as it does right now: two literature classes, a freshman writing class, and a team-taught auditorium humanities course with 60 students. This minute, as I sit here, I am in possession of approximately 75 papers, ranging in length from 950 to 2000 words, that need grading. And finals are in two weeks. It’s the absolute WORST, you guys.

The article linked above cites arguments from skeptics, mostly claiming that a computer program cannot actually “read” an essay. As a committed posthumanist waiting impatiently for my cyborg body, I have less of a problem with the concept than those detractors. It would not surprise me so very much to find that a computer program could determine whether a standard academic essay were well organized and supported. But that’s only half the battle of essay marking. The computer would not know, for example, if an argument that seemed out of place in an essay derived from a conversation we had in class. The computer would not have worked with a struggling student on draft after draft and thus recognize improvements and effort that indicate so much more than the final product alone. Basically, my problem isn’t that the computer isn’t a person, but that the computer wouldn’t be me. If I don’t read my students’ essays, I have very little idea what they understand or think about the material we’re studying, and thus little idea how to adjust my instruction. Moreover, the ones who refuse to speak in class–whose names I often have trouble learning until I get a feel for their writing–would remain ciphers.

Ultimately, when the brief (but delicious) fantasy induced by the article faded, I had to conclude that a program like this might be useful for students trying to write tighter academic essays in general but was unlikely to be useful to me as a grader, especially in literature classes where arguments are based on interpretation rather than statements of fact. I can see myself using a program like this to tutor students in basic essay construction but, alas, I don’t think it’s going to take any grading off my hands anytime soon.

It's time for a puppy.

I have a student to thank for the next quote and the two videos on this post, one of which is a song for MUSICAL MONDAY.

I had not thought of WEEN in quite some time before a student reminded me of their existence.

A Sense of Doubt blog post #1761 - Margaret Atwood on Marriage from Brain Pickings

A Sense of Doubt blog post #1761 - Margaret Atwood on Marriage from Brain Pickings

Not trying to say anything here. Just a re-share that I like. I mean, hey, I have an Atwood category. Plus, I am a week behind as I type this. Final grades knocked me out. Post final grade recovery was three days long.


https://www.brainpickings.org/2019/12/09/margaret-atwood-habitation-marriage/

Margaret Atwood on Marriage

“I hold this to be the highest task of a bond between two people: that each should stand guard over the solitude of the other,” Rilke wrote in his meditation on freedom, togetherness, and the secret to a good marriage. But how do two people protect this sacred necessity of the bond from the daily proximity of cohabitation, which now presses their closely neighboring solitudes into inevitable frictions, now pushes them apart into neighboring lonelinesses?

That is what Margaret Atwood explores in a short, stunning poem originally published in her 1970 collection Procedures for Underground, later included in her altogether wondrous Selected Poems: 1965–1975 (public library), and read here by musician, poetry-lover, and my dear friend Amanda Palmer to the serendipitous sound of church bells in the winter-quieted streets of Portugal.

HABITATION
by Margaret Atwood

Marriage is not

a house or even a tent
it is before that, and colder:
the edge of the forest, the edge

of the desert

                the unpainted stairs

at the back where we squat

outside, eating popcorn
the edge of the receding glacier
where painfully and with wonder

at having survived even

this far
we are learning to make fire

Complement with Anna Dostoyevskaya on the secret to a happy marriage and Virginia Woolf on what makes love last, then revisit other soulful and stirring readings by Amanda (who supports her music and life-poetry, like I do my writing and life-poetry, via donations): “When I Am Among the Trees” by Mary Oliver, “Questionnaire” by Wendell Berry, “The Mushroom Hunters” by Neil Gaiman, “The Hubble Photographs” by Adrienne Rich, “Having It Out With Melancholy” by Jane Kenyon, “Humanity i love you” by E.E. Cummings, and “Possibilities” by Wisława Szymborska.

A Sense of Doubt blog post #1760 - Archie has ideas - THAT ONE THING

While grading robot was being a robot that grades and does little else, he spotted this lovely panel clipped from an actual Archie comic on, yes,. INSTAGRAM. He was taking a grading break.

What might Archie be alluding to here? I mean, really? In the shower?

What's next? Does he drop the soap?

LOW POWER MODE: I sometimes put the blog in what I call LOW POWER MODE. If you see this note, the blog is operating like a sleeping computer, maintaining static memory, but making no new computations. If I am in low power mode, it's because I do not have time to do much that's inventive, original, or even substantive on the blog. This means I am posting straight shares, limited content posts, reprints, often something qualifying for the THAT ONE THING category and other easy to make posts to keep me daily. That's the deal. Thanks for reading.

Grading robot has been making like a robot with pistons for hands, and it's Monday 12/16 18:23 hours as I send this post back in time.

The image is the one thing of THAT ONE THING.

It came off a student's paper.

Pretty awesome, huh?

Sometimes, I feel like they actually care about their work and that they have learned things.

And then I read the next essay...
