I got three bags of sand and I'm waiting for the man.

HW 1

Dear Everyone,

Homework the first has been posted in the Assignments tab. It is due Thursday, 6 February 2014, at the beginning of class.


Barnett Newman was an American Abstract Expressionist who is particularly noted for his “zip” paintings, which are characterized by vertical strips that contrast with the rest of the work. This one’s called “Vir Heroicus Sublimis” (“Man, Heroic and Sublime”). Newman wrote a related essay called “The Sublime Is Now” and you can read it here. I do think it’s a good idea for an artist whose work is as abstract as Newman’s to do some writing in order to expound on his artistic philosophy and sensibility. Seems only right. The painting is in the MoMA, so you have no excuse not to see it at some point in your life, especially since Stony Brook students get in for free. Just go to the information desk, show your ID and be like “Eyy whatup gurl lemme get a ticket” and they have to give you one. It’s the law.

“During the Middle Ages, probably one of the biggest mistakes was not putting on your armor because you were ‘just going down to the corner.'”

– not Barnett Newman

Office Hours Wednesday 29 January

Hello all,

I will be in my office from 1-2 pm on January 29th, rather than my normal Wednesday hour of 11am – noon.


“The wise man can pick up a grain of sand and envision a whole universe. But the stupid man will just lie down on some seaweed and roll around until he’s completely draped in it. Then he’ll stand up and say, ‘Hey, I’m Vine Man!'”

Final exam grades are posted

Final exam solutions

You may be interested to know that the final exam solutions are now available in the Documents tab. You may not be, though. I wouldn’t blame you. I hope to finish grading the exams by tomorrow night and have the final grades done by Friday. But as we all know, the best-laid schemes o’ mice an’ men gang aft agley, so no promises.


p.s. I did the extra credit page, too — including the picture. Let’s just say I ain’t no Picasso
(Woman in Blue)
or Jacques-Louis David (The Coronation of Napoléon)
or Caravaggio (Judith Beheading Holofernes)
or Kasimir Malevich (Black Square)
Okay, maybe I am a Kasimir Malevich.

Final reminder / a sonnet / some more art for you to enjoy or ignore

The hour of reckoning is almost upon us. Your final exam will take place tomorrow, Tuesday 17 December 2013 from 8:00 a.m. to 10:45 a.m. in our regular classroom, Humanities 1003. Be there or be square (where square = satisfied with your current grade as described in previous announcements). No graphing calculators allowed. You can write on both sides of your cheat sheet.

The format is as follows: section one has two problems, both of which you must answer. Sections two through four have three problems each; you must complete two problems from each of these sections.I wrote a sonnet for inspirational purposes. It’s Petrarchan in spirit, if not exactly in form (I go ABBACDDC in the octet, rather than ABBAABBA).

 

No spirit wearies not, to bear the toll
Of daily life, small burdens, cruel misdeeds.
Unsated tastes and unacknowledged needs —
Too common, all too toxic to the soul.
And weakness gestates, stealthy and perverse
When granted berth by pettiness and greed.
It siphons strength; the impetus to lead
Subsides, our fate resigned to with a curse.
But let reserves of heroism swell!
Until the reservoir o’erflows its side.
Though latent genius seems always to dwell,
It tarries not beholden to the tide,
Nor to the stars. Assert control; live well.
Reject malaise and mount the world astride.


 

Caspar Friedrich was a 19th-century German Romantic landscape painter. He killed the game.

Wanderer Above the Sea of Fog:

The Sea of Ice:

Friedrich didn’t get too many props in his day, but by the turn of the twentieth century a lot of peeps were like “Ayo Caspar was pretty dope tho damn!” and he is now cited as an influence on many artists from that period forward, including Gerhard Richter, the man whom a recent Vanity Fair article declared “our most admired living artist” based upon the results of a survey of 100 art-world cognoscenti. The top six artists were, in order: Richter, Jasper Johns, Richard Serra, Bruce Nauman, Cindy Sherman, and Ellsworth Kelly. No big surprises there. Ai Weiwei, John Baldessari, Jeff Koons, Kara Walker, and James Turrell were among the also-rans. I was slightly surprised that Chuck Close didn’t garner any votes. His massive portraits at the Met are worth long looks, but you really have to see them in person.

Incidentally, Gerhard Richter gets hipster cred by virtue of the fact that Sonic Youth used his painting Kerze (“Candle”) as the cover art for their magnum opus Daydream Nation.

Office hours this week / exam 3 ready for pick up

    – I just received a delivery to my office of the graded exams, so if you want to come by and pick yours up, I’ll be here for a while — probably past my bedtime. If I leave the office I’ll put the exams on a chair outside my door. 

    – Tomorrow (Tuesday) I will hold my usual office hours from 3 – 5pm, and Wednesday I will have office hours from 2:30 – 5:30 pm. If you just want to come by to get your exam, that’s okay, too. I ain’t mad atcha.
    – I also recommend getting your old homework assignments from me so that you may study from them. I have a whole bunch in my office. On the bright side (literally!) they’ll be excellent tinder for a bonfire if you don’t collect them.
    – Just to be clear, I used the first eight homework grades to calculate those weighted average percentiles, but your final averages will be computed using the best eight homework grades. I only used the first eight because those are the ones that are graded
    – I know it might be getting annoying, but this is the last time I mention them, I swear: the course evaluation period ends today so if you’ve not yet done, please fill it out here. If you really don’t want to do it, that’s okay. I understand. I just wanted to mention it one last time in case some of you have been putting off doing it. We’re at 47.75% reporting, which is good (I think) but it’s tantalizingly close to half so I decided to risk coming off as a boor and put in a final plea. Thanks for tolerating it.

J.M.W. Turner was a boss:

He was the original “Painter of Light,” regardless of the trademark that bum Thomas Kinkade registered. Kinkade was one of the wackest artists of all time, but I admit he is kind of a fascinating figure. If he weren’t so omnipresent his work would be merely laughable, but his commercial success is such that seeing a Kinkade print actually makes me kind of angry and/or nauseous. And that fact, that I have a reaction to it, forces me to consider his merits as an artist. There’s a Thomas Kinkade store in Port Jefferson, right down Main Street from the decent cheese shop C’est Cheese. Makes me wanna holler.

Some notes on distribution

    As many of you no doubt noticed, the exam 3 grades are posted. A number of people earned a perfect score, mad props for that. Here’s a table with statistics for each of the exams as well as for weighted averages that I calculated as follows:

HW + .24*(exam 1 grade) + .28*(exam 2 grade) +.28*(exam 3 grade)
where HW = average of your first eight homework assignments (out of 20 points). Obviously this statistic isn’t perfect, but it’s as good as I can do at the moment. Keep in mind that the rightmost column will change after the final, and it will almost certainly go up 

    

Exam 1 Exam 2 Exam 3 Weighted Average
25th percentile 55 48.5 70.75 58.52
median 66 68 84 71.77
75th percentile 78 81 90.25 81.93
85th percentile 84 85.2 95 86.15
    As for the final: the reason I made it optional was basically to benefit those of you who have done really well this semester. If you have excellent marks already then you have nothing left to prove on the final, since you’ve already been tested on all the material, so I figure why should I make you sit for a final. Most of you should want to take the final, as it is an opportunity to show what you know and make up for any poor performance earlier in the semester. You’ll have the sheet of notes, so you don’t have to worry about memorizing everything from the whole semester; also, you’ll have choices about which problems to do. 

I saw a painting I liked by Chaim Soutine at the MoMA:

  
It’s called Man in a Green Coat. Soutine lived in Paris around the same time as Amedeo “Mo Diggity, Mo Doubt” Modigliani (and a million other great artists like Chagall and Picasso and all those big dogs). Modigliani is the more famous artist, but that could be partly because of the mythos surrounding his reckless lifestyle (he was a tremendous drunk, hit the hashish hard, and chased the green fairy all around Paris (but mostly Montmartre) until he died at 35). Modigliani painted Soutine a couple of times:
  
but a better work of his is the Red Nude, which I’m not going to post in case some of y’all are sensitive like the Paris Chief of Police who in 1917 shut down Mo Diggity’s exhibition for being too scandalous.

Final Exam

 The final exam will be on Tuesday 17 December 2013 (Beethoven’s birthday! Also William Safire’s.) from 8:00 a.m. to 10:45 a.m. Eastern Standard Time (UTC-5). It will be given in the usual classroom, Humanities 1003. It will be cumulative; that is, it will potentially test you on any material covered throughout the course of the semester. You will be allowed to bring one 8.5” x 11” sheet of paper on which you’ve written theorems, examples, definitions, spaghetti alla puttanesca recipes, “Ryan Gosling” in a big heart, or whatever else you feel like. You will not be permitted to use a graphing calculator, but four-function and scientific calculators will be permitted.

 As promised, the final exam is optional. If you choose not to take it, your first three exams will be worth 24%, 28%, and 28%, respectively, of your final grade. Homework is worth 20% of your final grade regardless of whether you take the final, and the lowest homework grade will be dropped. You can calculate your score and decide whether you’re happy with it. I won’t know what the cutoff for each letter grade will be until after the final exam is done and all the numerical grades calculated, but I can say that if you have a 93 or better you’ll have an A, 90-92 will be at least an A-, 87-89 at least a B+, 83-86 at least a B, 80-82 at least a B-, 77-79 at least a C+, 73-76 at least a C, 70-72 at least a C-, and 60-70 at least a D. Barring a spectacular class-wide performance on the third exam (which will be graded soon, by the way) and the final, those will not be the final cutoff marks. That is, you can probably get an A with a 90, a B+ with an 85, etc. I really don’t know, though, so I’m not going to promise anything.
 If you do take the final, the weights are: exam one, 15%;  exams two and three, 20% each; final exam, 25%. If you do better on your final exam I will weight it more heavily. For example, if you got a 45, 70, 75 on the first three exams and an 80 on the final I would probably do something like 10% first exam, 18% each of second and third exams, 34% final exam. I’m still figuring it out, since I want to be consistent for each student. Basically, just realize that the final is an opportunity to make up for poor performance on previous exams.
 I will have office hours next week, probably on Wednesday and Thursday afternoon. I’ll send out an email in a couple of days with details. I’ll also let you know about the distribution of the third exam grades. In the mean time, the best way to study is by redoing all the problems from the old exams and homework assignments, without the aid of your notes or textbook.

 Let me tell you the story of how I fell in love with cheese. A few summers ago, I was travelling around Europe with a friend before our semesters abroad began. Her programs was in Rome, so we ended up there, but I had another week before I had to be in Madrid, so I had some time to gallivant about by myself. After a few days in Italy I took an overnight train to Bern, Switzerland, getting in around 6:30 a.m. The morning chill was a welcome respite from Rome’s 95-degree heat, and I put on a sweater over a shirt that I buttoned all the way up to the top. I was feeling good.  
 Unsurprisingly, nothing was open at that hour, so I just walked around for a while. The alpine air was a blessing after five days of Italian humidity. When I walked along the Aare River, it seemed somehow clearer than normal air, so that I felt as I had the first time I put on glasses and realized all I had not been seeing. I saw a beautiful woman coming towards me on the sidewalk. As she passed me she smiled and said “Bon style !” and I began to wonder how difficult it would be to become a Swiss citizen. I wandered some more until I reached a square where a market was materializing. I hadn’t had breakfast, but an array of samples drew me to the fromager’s table rather than the boulanger’s. I was going to buy some gorgonzola, but then I realized what a folly it would be not to try something new. So I had a bite of a semi-hard, raw cow’s-milk cheese called Mont Vully, named after the mountain in whose shadow it was made about thirty minutes away. 
 I don’t know if it was my mindset, or the setting, or if it was just a particularly good batch of cheese, but as I tasted the Mont Vully I began to feel inexplicably giddy, as if I were being let in on a tremendous secret, or getting away with something illegal. I’d had Roquefort before, but outside of blue cheeses I’d never experienced such an assertive flavor. It was assuredly a stinky cheese, but while assaultive to the nose it was divine on the tongue. I spoke briefly with the proprietor, and when my poor French reached its limit, I bought about half a pound of the revelatory Mont Vully and went on my way. That evening I went to Paris, where I slept at a hostel. I kept what was left of the cheese in my shared room, no doubt to the chagrin of my fellow-travelers and their sensitive nostrils. No matter, though. It made for a delightful breakfast.
 

Exam 3 material

Sorry this is a bit late; this week’s been crazy (this whole year’s been crazy, ask the holy spirit to save me, only difference from me and Ossie Davis, gray hair maybe). 

Come to my office hours tomorrow for help and to pick up your homework 8. 
The solutions to homework 9 are now posted.

To do well on Exam 3 you should know all about the following:

– Linear independence
– The span of a set of vectors
– Subspaces 
– col(A), row(A), null(A)
– rank(A)
– Linear transformations
– The condition number of a matrix and what means (Section 3.5)
– Linear regression (Section 4.2)
– The pseudoinverse of a matrix and what it is used for (Section 5.3)
Types of problems are:
– Determine whether a vector is in the span of some set of vectors
– Determine whether a set of vectors forms a basis for a space
– Prove some given set S is a subset of R^n, or finding a counterexample to show that it is not
– Prove that some given transformation T is linear, or finding a counterexample to show that it is not
– Find solution sets to underdetermined, consistent systems
– Find bases for col(A), row(A), null(A)
– Find the dimension of a space 
– Find the rank of a matrix
– Given enough information about A to find its condition number without too much calculation, find cond(A). Given error matrix E, explain what cond(A) tells us about the possible error in our solution to the system Ax = b
– Find q in a regression model y^ = qx
– Find q for a more complicated model by converting data into values that are linearly related (as in section 4.2 #7, 8)
– Set up the regression problem y = qx + r as Xw = y and find least-squares solution w = [q, r] = (pseudoinverse(X)) * (y)
– Given enough information about A to find its pseudoinverse, find the least-squares solution w to Aw = b (the previous bullet point is a special case of this problem)
The best way to study is to redo the homework problems without using the textbook or your notes. Every problem on the exam is similar to some homework problem from the past few weeks.

Saw this painting in the MoMA last week, thought it was pretty dope

HW 9

The last homework is here. It will be due Monday 2 December 2013, in class. 

Section 4.2: 7, 8
Section 3.5: 20
Section 5.3: 1, 2, 3(a) and (b)
You’ll want to use a computer to calculate some of the matrices in some of the problems. I recommend using Matlab through the Virtual SINC site:
To borrow a phrase from Rubeus Hagrid: it’s dead useful.

Sometimes when I listen to a lot of new music it is a little overwhelming and it’s hard to remember what was good and what was not so good. So sometimes I’m a little surprised when I go back to certain certain artists and I have that old familiar feeling of listening to a song that I like. It’s a good feeling. Anyway, 

Banks (she has more danceable songs like this one, which is not to be confused with the track of the same name from earlier this year by Iggy Azalea (new remix dropped recently is pretty good, if somewhat brostep for my taste), 
Deptford Goth (he’s kind of like James Blake meets The xx except a little less minimalist), 
Adesse (sample on that track is from O Superman by Laurie Anderson, who’s OG and the recent widow of Lou Reed, the legend. If you get nothing out of this class but the fact that The Velvet Underground were one of the best bands ever, I’ll have done my job (okay, not really, but they were amazing. Their début was the first album I ever bought on vinyl)),
and Perera Elsewhere are pretty good.
In other news, winter is coming:
