Obama / McCain Debate #2 – Live!

October 7th, 2008

Starting late tonight, since we were busy reading to Cate.

9:23 – McCain is riding hard on earmarks, which seem to be just a distraction so folks won’t notice other problems.  Points out that Obama supported funding a planetarium.  This was meant to be a slam on Obama, but sounds like a pretty good idea to this science educator.

9:25  McCain’s still talking about bipartisanship.  Mentions working with Joe Lieberman.  So working with Lieberman – who is a Republican in all but name now – counts as reaching across the aisle?

9:27 Obama: “McCain likes to talk about earmarks a lot.”

9:28 Can someone take the crackers out of Tom Brokaw’s mouth, please?

9:30 McCain “We’ll have to have an across-the-board spending freeze”.  That sounds like panic rather than an economic plan – as if McCain’s just going to throw his hands into the air and give up trying to figure out what’s going on with spending and taxation.  And if McCain’s going to freeze spending, how’s he going to “get to work right away” on health care?

9:31 Obama reminds us of Bush’s “Go out and shop” after 9/11.  He also reminds us that “earmarks” are a small part of our current troubles.  Says McCain’s freeze proposal is like using a hatchet when a scalpel is more appropriate.  That’s a pretty good analogy.  Across-the-board cuts/freezes screw everything up instead of curtailing wasteful spending.

9:36 McCain says that Obama will increase taxes on half of small businesses.  I suspect Obama to hit back on this.  McCain says he doesn’t want to cut taxes for the wealthy.  That’s news.  Cutting taxes for the rich has been McCain’s stated plan from the day he began his preparations for this year’s election.  McCain also seems to think Obama favors “mandates” and “fines”.

9:27 Brokaw fails to allow Obama to respond to McCain’s bull.  Obama looks pretty pissed off about it.  Good for Obama.  So far, I’m not impressed with the format.  Looks like Obama’s going to go back to addressing McCain’s statements anyway – in answering the question on entitlement programs.

9:41 McCain He knows how to fix Social Security.  Says it’s easy, in fact.  He just won’t say what his solution is.  (This is probably because his solution would cost him the election.  Perhaps he wants to privatize it?)  Brings up the “94 tax increases” thing.  We’ll see if Obama hits him like Biden hit Palin for the same remarks during the VP debate.

9:43 A question for McCain about what he’ll do to make Congress move on climate change.  Nuclear power is the cure to all our ills, he say.   Oddly, though, he points out that he failed to get his proposal on climate change through Congress.  Sorta like he did the first time with the bailout bill when he “suspended” his campaign to push the bill through.

9:46 If McCain is going to play the “Obama voted xx times to raise taxes”, Obama’s going to hit McCain the same way on his environmental record.

9:48 Brokaw wants to know about whether we should start a “Manhattan project” for alternative energy.  McCain:  Pork-barrel projects!  Obama gave tax breaks to oil companies! Drill here, drill now!  What?

9:50 In terms of format, this debate is asinine.  What’s the point of a “debate” if the candidates aren’t allowed a rebuttal for obvious attacks?  I came here for an argument!

9:52 Obama brings up McCain’s “giveth with one hand, taketh with the other” proposal to give a tax credit and then tax employer-provided health care.  McCain talks about “shopping around” for insurance. Call me crazy, but I sure as hell don’t want to “shop” for health insurance.  Heck, I have allergies – I suspect the coverage I’d get on the open market would be much worse and much more expensive than what I have now.

9:56 McCain:  Health care is a “responsibility”.  Obama:  Health care should be a “basic right”.  I think that’s about right.

10:00  WordPress eats my last few comments.  Obama did respond effectively to McCain’s implications that he would need “on the job training” – saying that there are some things he doesn’t understand – like the reason we invaded the wrong country after failing to finish the job in Afghanistan.

10:06 “The McCain Doctrine” appears to be “Attack Obama First”.  And what’s with this “another Holocaust” thing that McCain mentions over and over?

10:14 Obama slaps back at McCain’s insinuation that he wants to invade Pakistan.  “Bomb bomb bomb Iran”  “Next up, Baghdad!”  McCain gets silly in response:  He “knows how to get bin Laden”, but he can’t tell anyone.  He’s said this before.  But why he hasn’t told … say … the current government about his great plan, so bin Laden might be brought to justice?

10:20 The Russia / Georgia stuff is the same thing they said in the last debate – both for McCain and Obama.  Where’s the fast-forward button on the live debate?

10:25  Oh, not this “preconditions” crap from McCain again.  It wasn’t convincing during the last debate, and it’s not convincing now.  It’s not even relevant to the question being asked.

10:31  Okay, the last question asked is one of those trick interview questions.  “What don’t you know?”  I suspect Obama and McCain will just use this to make their closing statements  Yup – that’s exactly what they did.  McCain says we need a “steady hand at the tiller”.  Sounds like he just endorsed Obama rather than his wild, maverick-y self!  Come to think of it, I didn’t hear the word “maverick” at all.  Is this the death of John McCain’s self-proclaimed “maverick” status?

Here’s the debate transcript.

Palin on climate change

October 7th, 2008

Here’s what VP candidate Palin had to say on climate change during the VP debate:

Yes. Well, as the nation’s only Arctic state and being the
governor of that state, Alaska feels and sees impacts of climate change
more so than any other state. And we know that it’s real.

I’m not one to attribute every man — activity of man to the changes in
the climate. There is something to be said also for man’s activities,
but also for the cyclical temperature changes on our planet.

But there are real changes going on in our climate. And I don’t want to
argue about the causes. What I want to argue about is, how are we going
to get there to positively affect the impacts?

We have got to clean up this planet. We have got to encourage other
nations also to come along with us with the impacts of climate change,
what we can do about that.

Someone in the McCain campaign must’ve told her to tone down her opinions on climate change from outright denial to mere incoherence.  Earlier, she was more forceful with her denial.

“I’m not one though who would attribute it to being man-made.”

One question I’d have for Palin is this:  If you don’t believe that human activity has anything to do with climate change, then what do you expect humans to do about climate change?

If human activity isn’t responsible for climate change, what will she ask other nations to “come along with us” and do?

And as an aside, it seems that we have already had a chance to team up with other nations on the environment.  We didn’t do so well.  (I don’t recall Palin supporting that initiative, either.)

Palin/Biden liveblogging

October 2nd, 2008

9:10 Palin says that Obama votes with his party most of the time, and that doesn’t represent change.  Haven’t the Republicans been in power until very recently?  And don’t they still hold the presidency?

9:12 So far, Biden attacks McCain and hasn’t had much of anything to say about Palin.  He gets in a good hit on McCain on his “let’s do for health care what we did for banking” remark.

9:13:  Palin “Darn right”.  Take one drink every time she says this during the debate, and you’ll never make it to the end.  She also brings up Obama “increasing taxes on people making $42000 per year”, which is false.

9:14 Biden fires back at Palin about deregulation, says that McCain voted to raise taxes more than Obama by Palin’s standard.

9:16 Biden says 95% of taxpayers get a tax break under Obama, while McCain’s tax plan benefits the rich.

9:17 Palin:  She’s always been in the “middle class”.  $500K custom-built lakehouse?  Private plane?  Riiight.  Palin misfires, I think, on health care.  It’s the private sector that’s in the doghouse right now.  I’m guessing lots of folks out there wouldn’t mind universal healthcare right about now.

9:20  Biden: 95% of small businesses wouldn’t see a tax increase.  Also points out that McCain will tax health benefits.  Good.  He also points out that people will lose insurance and the tax credit won’t be enough to replace it.  He calls McCain’s health plan a “bridge to nowhere”. Zing!

9:22  Palin:  McCain doesn’t tell one thing to one group and another thing to another group.  Riight.  She also says she “took on” the oil companies.  Doesn’t explicitly say she taxes the oil companies, though.  Palin says that the doesn’t have to cut back on any promises due to the bailout because she hasn’t been on the national scene long enough to make any promises.  What the heck?

9:25 Biden points out that Alaska does have a windfall profits tax – like the one Obama supports and McCain doesn’t.  Biden says Palin should convince McCain to do likewise.

9:27 Does Palin know about any financial institutions other than Fannie Mae and Freddie Mac?

9:28 Bankruptcy bill.  Good of Biden to stay away from that topic, since he’s on the wrong side of it.

9:29 Palin seems to think she’s an expert on energy independence.  By saying that it’s something we should do.  Hmm.  Oddly, she seems to never mention alternative energies to oil.

9:31  Palin on climate change.  Admits it’s real, still waffles on it being man-made.  Biden states that it’s man-made.  Points out how much energy we use, and accuses McCain of voting against alternative energy (20 times).  Finally, someone mentions alternative energy.

9:34  Palin:  “Drill, baby, drill” for “hungry markets”.  Says offshore drilling is clean and safe.

9:36 Biden: Supports “rights for same-sex couples”.  Palin blathers about not wanting to “redefine marriage” but is “tolerant”.  Biden doesn’t support “gay marriage”, but no civil distinction between the two.  So what the heck is Biden talking about?

9:40 Palin:  Petraeus, surge, etc.  You’ve heard it before.   Accuses Obama of withholding money from troops.

9:41  Biden: McCain also voted to withhold money from the troops – because the bill had a timeline.  Wants to “end this war”.

9:43 Palin says that withdrawal is “a white flag of surrender”.  Brings up “cutting off finding for the troops” again.  If at first you don’t succeed …

9:46  Biden talks about Pakistan.  An unstable Pakistan, he says, more a worry than Iran because they already have nukes.

9:48 Palin:  Channeling one of McCain’s more asinine comments from the last debate – that it’s silly to meet with enemy leaders.

9:50 Biden:  Brings up the McCain Spain gaffe again.  I suppose that Palin can’t hit back because McCain doesn’t want to admit he got confused?

9:55 Palin says that you can’t criticize the past if you want to change?  Huh?

9:56 Take one drink every time Biden says “George Bush” – as in, McCain is just like.  It’s true, of course, that you shouldn’t elect another conservative Republican if you want to move away from conservative Republican policies.

9:58  Biden:  “Facts matter”.  Surge won’t work in Afghanistan (according to the military), since we need to build infrastructure, etc. And we don’t spend money there.  3 weeks of Iraq = 7 years of Afghanistan in terms of money.

10:00 Palin’s response:  SURGE!

10:04 Palin really likes that “Obama voted against funding the troops” point.  Wonder if Biden will point out McCain doing the same thing … again?  It’s probably dangerous to attack Biden on his AUMF vote.  McCain voted the same way, and Obama spoke out against it.  Don’t folks vote for the TOP of the ticket?

10:07 Palin says “McCain knows how to win a war”.  He does?

10:09  I think Palin has called herself a “maverick” more than McCain has.  I still say that “maverick” is a title that no one can self-apply.

10:11 Palin says that Obama/Biden ticket will destroy your jobs and raise your taxes.

10:12 Palin: I still don’t get Palin’s whole “you can’t criticize the administration” thing.  If you’re running for change or reform, you kinda have to point out the flaws of the current administration.  Perhaps she doesn’t want to hear McCain being hammered with his recent agreement with everything Bush stands for.

10:18  I’m not sure what Palin was saying about the vice presidency.  Biden at least answered the question.

10:19  Palin has “a connection to the heartland”?  I somehow doubt that someone with a half-million dollar home really has to worry about how they can pay college tuition.

10:21  Palin admits folks are looking for change.  Says McCain’s a “maverick” (twice) and will bring change.  Good opening for Biden to bring up “voted with Bush 90% of the time”.

10:23 Biden takes the opening.  Slams McCain on his rather conservative voting record and his agreement with Bush – he’s not really a “maverick”.

10:28 Palin says exactly the same thing she said before about Obama/McCain “will kill jobs and raise taxes on workers”.  She likes to “answer tough questions” (by not answering them?  Most of what Palin’s said has had little to do with the moderator’s questions.)  Claims to be an “average, middle class” person.  Someone should point out to her what the median annual household income actually is.  It’s okay to be rich, but it’s not okay to lie about it and pretend you’re not.  She gets in a “POW” reference, of sorts, for McCain

10:31 Nice ending by Biden.

PBS pundits say that Palin “held her own”.  This seems to be what the TV folks are saying.  They seem to like the “soccer mom”, “joe sixpack” stuff.  Do most folks really want a “soccer mom” or “joe sixpack” a heartbeat away from the Presidency?

My initial take:  Palin didn’t burst into flames on the stage, so on that scale she did well.  Biden certainly showed that he was much more fit for the office.

Here’s the transcript.

Having it both ways

September 30th, 2008

There’s some argument on the merits of partial credit – giving students some points for getting at least part of a complex answer correct.  Sometimes, partial credit is beneficial – but the existence of partial credit causes another problem:

Some students simply won’t commit to an answer, hoping to somehow pass on a wave of partial credit.  As an example, consider the question below.  It’s part of a lab write-up where the students measured the pH of a solution of sodium hydroxide using pH paper and other indicators.

Question: Was the solution acidic or basic? _________________
Student answerAcidic, with the presence of base

Of course, the correct answer is “basic” – which was very obvious if the student had even glanced at the directions for using the indicators.  But instead of doing that, this student just thought he’d wing it, get done with the lab write-up a whole minute faster, and try to get points for his answer anyway.

I imagine that students keep trying this strategy because it has worked somewhere before.  But not today.

Some debate thoughts

September 27th, 2008

Last night, I watched part of the Obama-McCain debate.  Since I only saw about the last half of the debate, I’m not going to try to say who “won”, overall.  But here are a few assorted thoughts.

  • Like many other folks, I found it off-putting that McCain couldn’t bring himself to look at his opponent.  He also took every opportunity to sneer condescendingly at Obama – talking no fewer than five times about how Obama was “naive” or “didn’t understand” some point of foreign policy.  Oddly enough, he did this even on Georgia. where Obama and McCain are rather similar.  For the part of the debate I saw live, McCain was in full-on “bitter old man” mode.  Bitter, obviously, that some young guy is running for the office that he is rightfully entitled to.  Especially bitter that this young guy is currently winning.
  • If you have to call yourself a meverick, are you really a maverick?  That’s like telling everyone how cool you are instead of actually being cool.
  • How many wars will John McCain start by accident?  Unless he’s much more in control of himself across the table from leaders of rival nations than he was at the debate, quite a few.
  • McCain dug himself a nice, deep hole with the flap over “preconditions”.  Perhaps he should go discuss this with his advisors?
  • I’d like to have seen Obama hit McCain a little harder.  For instance, there was no mention of McCain’s rug-buying expedition with Lindsey Graham, where McCain McCain visited a market while under heavy military guard and then claimed he walked around freely.  Still, I understand that Obama needs to not be seen as overy angry.  He must be the cool-headed leader that Americans can depend on in a crisis.

How could I have missed the most crucial issue of all?  NotVeryBright urges us to consider the flag pin issue! Obama had a flag pin, McCain didn’t!

Keeping up with the meltdown

September 25th, 2008

I hear that John McCain has “suspended” his campaign so that he could swoop back to Washington to save our financial industry.

Only he hasn’t actually read the details of the plan the administration want the Congress to pass.

Asked by the NBC affiliate in Cleveland about whether he was prepared to support Paulson’s plan, McCain said, “I have not had a chance to see it in writing. I have to examine it.”

I’m not campaigning, but I do have a pretty busy schedule.  But my lab students have just started plotting their data for the freezing of acetic acid.  That gives me a few moments where I don’t have much else to do.  Here’s Paulson’s plan.

Now that I’ve read the plan (and my students are still plotting), I have some qualms with it.

Sec. 6. Maximum Amount of Authorized Purchases.

The Secretary’s authority to purchase mortgage-related assets under this Act shall be limited to $700,000,000,000 outstanding at any one time

Aren’t conservatives generally against “throwing money at a problem”?  That’s always the line wen someone wants to use a little more money to improve education.  7×1011 dollars is a lot of money.  It’s about $2300 from each person living in the USA.

How will this sum of money help address the root causes of the meltdown?  At least with education spending, you can generally point at a few things that can be fixed with the money (class sizes, worn facilities, etc.).  Does buying bad debt off of financial institutions discourage them from taking on more bad debt in the future?

Sec. 8. Review.

Decisions by the Secretary pursuant to the authority of this Act are non-reviewable and committed to agency discretion, and may not be reviewed by any court of law or any administrative agency.

Anyone else have problems with this?  Lack of oversight of the financial markets is part of the reason we’re in this mess.  How will giving someone a bunch of our money and agreeing to not hold him accountable in any way for it fix the problem?

Friends, does your milk powder taste different lately?

September 22nd, 2008

It looks like there’s trouble in China.  Supplies of milk powder meant for Chinese infants are tainted with melamine – the same chemical found in last year’s dog-food scare.

On Sept. 17, China’s minister of health, Chen Zhu, announced that three babies had died, more than 150 were suffering from acute kidney failure, and an additional 6,000 infants had become sick after drinking milk made from milk powder tainted with melamine.

Now you might be wondering why on earth a company would add melamine to powdered milk.  Could it have been accidental?  Or was there some reason to add this compound?

Consider this:  The amount of protein in foods is often determined based on total nitrogen content.  That’s because proteins contain a fairly regular amount of nitrogen – about 16% by mass.  Take the total nitrogen content, multiply by a conversion factor, and you have a good estimate of protein content of the food.

Take a look at melamine.

Melamine, C<sub>3</sub>H<sub>6</sub>N<sub>6</sub>.  Nitrogen atoms are indicated in blue.

Melamine, C3H6N6. Nitrogen atoms are indicated in blue.

Simple assay methods for total nitrogen content can’t distinguish the nitrogen in melamine – which is about 67% nitrogen by mass – from the nitrogen in proteins.

The tested substance appears to have a higher protein content than it actually does – since analysts assume that almost all the measured nitrogen comes from actual protein.  This is a reasonable assumption for uncontaminated materials, but is open to abuse by the amoral.

It amazes me that the Chinese were caught by this same ruse again.  You’d think that after finding melamine added to pet food, the Chinese government would have gone ahead and made sure nobody was adding it to food for humans.

Brunswick Stew-pid

September 18th, 2008

Looks like our northern neighbor is affected by the same disease that Upstate SC has:

the Brunswick County school board began discussions on teaching creationism alongside evolution – something all four board members present showed a strong interest in. The talk began after Joel Fanti, a parent and graduate of the school system, told the board that he considered it a problem to teach evolution as a fact and that science teachers should include creationism in the curriculum, as well.The audience applauded.

… a case of The Stupid.  At this point, it seems that the state will squash this little Stupid outbreak.  The higher-ups in the NC school system recall the Dover trial.  This, after all, would be a more blatant attempt than the one in Dover to replace science with religion in the science classroom.  A lawsuit would almost certainly follow.

One more disturbing point:

Teachers have alternative assignments for students whose parents have objections about evolution, but students are still assessed on the topic in state tests

Lovely.  Parents can opt their kids out of biology, but teachers are still held responsible for students whose parents won’t allow them to learn?

Palin’ in comparison

September 17th, 2008

I haven’t had a whole lot of time to blog lately, but I can’t resist laughing at the culture wars.  Yglesias links to this post from an “oasis of rational conservatives”, titled “THIS IS ALL YOU NEED TO KNOW”:

THIS IS ALL YOU NEED TO KNOW

THIS IS ALL YOU NEED TO KNOW

So … the Democratic nominee for President can ride a bike, while the Republican nominee for Vice President can stand in front of a motorcycle?

But this post really compares apples to oranges.  They should have McCain on a motorcycle (making sure to hide the scaffolding holding him up).  That, or find a picture of Joe Biden on a bike.

Be Prepared

September 8th, 2008

This blog has been very quiet lately.  Sorry about that, but when you’re preparing for five labs a week in addition to lecture courses, things get a little … hectic.

That said, we’re four weeks into the semester down here, and we’ve started our labs.  I normally push the start of labs back a week, so as to avoid having people add my class after we’ve already done a lab and discussed lab safety.

A bit of the lab schedule

A bit of the lab schedule

The Labor Day holiday pushed the start of the “real” experiments back even farther – ample time for everyone to pick up one of these.

The laboratory notebook, also known as a 50-cent compostion book.

The laboratory notebook, also known as a 50-cent composition book.

… so why is it that half of the class comes to lab without even having attempted to buy a laboratory notebook?  It’s not like I’ve forced students to buy something exotic like the $25 lab books I had to buy when I was an engineering undergrad.  Just about every store in the area that sells school supplies stocks these composition books!

Or were these folks simply not paying attention?

You know, if we could figure out how to solve America’s attention-deficit-disorder problem, that would go a long way to solving our other problems.  Just sayin’. 🙂
