Kids being kids

Slashdot links to this article in Advertising Age about Wal-Mart trying to cash in on the success of Myspace, the home of approximately 6.022×1023 teen-to-twenties angst blogs.

Wal-Mart is launching a highly sanitized, controlled and rather unhip site at walmart.com/schoolyourway. Teens are invited to create their own page, “show it to the world and win some fab prizes,” including a chance to have their videos appear in a Wal-Mart TV commercial.

Isn’t that what any teen is just dying to do? Get into a Wal-Mart commercial?

The site is an attempt at closing the trend gap Wal-Mart now faces as Target wins more teen-apparel dollars.

Have people that do Wal-Mart’s advertising actually been in a Wal-Mart store? It probably isn’t lack of trendiness that keeps teens out of Wal-Mart. it’s that Wal-Mart stores are only slightly more filthy and poorly arranged than a flea market. (I will give them this – their stores are on average cleaner than the HTML markup on most myspace pages.)

“Over the last year, we have been getting increasingly bad feedback from teen girls about Wal-Mart in contrast to Target — especially Wal-Mart’s apparent lack of cleanliness, messy layout and lack of stylish attire. This attempt at ‘we media’ is terrific. We’ll have to wait and see if it’s enough to overcome in-store issues.”

My guess is “no, it won’t overcome in-store issues”. Whatever junk they put on the web won’t change the fact that the stores are hell to shop in.

But that Wal-Mart site ought to be good for some cheap laughs.

For example, to participate in Wal-Mart’s content, you have to agree to this:

I represent that my Entry is my original creation and hereby grant to Sponsor the copyright and all other rights now known or hereafter existing to use my Entry throughout the universe, in perpetuity, in whole or in part, in edited, unedited or distorted form, in connection with this Contest, for any trade, advertising, or promotional purpose whatsoever, without review, approval, notification or payment from or to any person or entity, in all media now known or hereafter discovered. I understand and agree that Sponsor shall be entitled to use, reproduce, modify, adapt, publish, translate, license, create derivative works from and distribute or incorporate Entries into any form, medium, or technology now known or later developed throughout the universe, for any purpose whatsoever.

(emphasis mine)

And you say Wal-Mart wants global domination. Pah! They will stop at nothing short of dominating the entire universe!

A public service announcement

Tuesday, July 18th, 2006

If you’re ever passing through Florence, SC on your way to Myrtle Beach (lots of Ohio folks do this), here’s a bit of advice. You might drive past a restaurant called International Buffet. An inviting sign like this may lure you in to eat.

[International Buffet]
Snow!! Crab Legg’s
(What … you mean you didn’t want to eat pantyhose for dinner?)

Whatever you do, do not stop! Drive on, and eat somewhere far away. You have been warned.

Should you decide to ignore my warning, you will come face-to-face with strange foods like “Cheese Cnabmeaf” which actually taste worse than they sound. Don’t believe me? See for yourself.

[International Buffet]
Cheese Cnabmeaf

For my money, there’s nothing like a good Chinese buffet. Unfortunately, International Buffet is nothing like a good Chinese buffet. The little card I picked up advertises “over 300 items” on the buffet. You might get to 300 if you count each piece of cnabmeaf as a separate item. Otherwise, you’ll fall about 225 items short. To be fair to International Buffet, this might be because they’re obviously a new restaurant.

Newness might excuse a lack of variety, but it does not excuse lousy food. We went at dinnertime – when you’d expect for there to be piping hot food on the buffet. International Buffet’s food had apparently sat on the bar for hours and was only lukewarm. By the time I managed to get back to my table with a plate of food, it had cooled to only slightly above room temperature. Politeness prevented me from doing this, but I briefly considered asking the waitress for a microwave. Cold Tso chicken is not very good. Cold cnabmeaf in melted-then-resolidified cheese is inedible.

International Buffet is located at 260 West Palmetto Street in Florence, SC. I advise planning your dining well clear of this address.

Save your pennies!

Oh darn! Where will I get the raw materials for making brass now?

Almost too weird for words

If you’re one of those who doesn’t believe that our schools should be teaching accepted science (particularly in biology), here’s the sort of person you’ll be proud to call an ally: Kent Hovind:

For years, he has claimed that he is employed by God and has no income or property because everything he owns belongs to God.

… and he likes to think that this will get him out of paying taxes on

$430,500 in cash [withdrawn] from AmSouth Bank between July 20, 2001, and Aug. 9, 2002, with each of 44 withdrawals for $9,500 or $9,600, just below the $10,000 starting point for reporting cash transactions.

Hovind is most widely known for his downright bizarre opinions on the age of the Earth and evolution. Looks like he understands the tax code only slightly better than he understands science.

Aliens vs. Fundamentalists

Thursday, July 13th, 2006

No, unfortunately, it’s not a new video game.

Via Sadly, No!, here is a series of articles called UFOs and the Gospel of Christ, by Ralph C. Barker: Part 1 is here and Part 2 is here.

If you scroll way, way down past the bazillion ads on the Part 1 link, you’ll get to the meat of the article – Seems Barker saw UFOs as a kid:

The only thing I do know is that the objects I saw violated every known law of physics. They flew at very high altitudes and performed almost instant, high speed, ninety-degree turns. Nothing flying, then or now, with the exception of Superman, can do this.

… to which I would simply say that as a kid he might not have been that familiar with every known law of physics. (Who is?)

The interesting thing about this article is that Barker’s point is to attack “New Agers” and/or UFO believers – not necessarily because they are spreading what most folks consider fanciful nonsense, but because

a very strong, obvious, and evil connection does exist between UFOs and the Gospel of Jesus Christ.

Barker asserts that people who claim to have contacted aliens report that:

The aliens don’t seem to be threatened by Islam, Buddhism, Hinduism, or any other ism. They focus their attacks on Christianity. Could this be because Christianity is the only true religion? This would be my bet.

… or is it more likely that Christianity is simply the dominant religious belief here in the USA? After all, if you’re brought up in the Christian tradition and are going to dream that you were abducted by aliens, it’s not likely that the alien races you make up in your head are going to suddenly give you a lecture on Buddhism.

Now the question is who inhabits the UFOs. Are they aliens? Are they extra terrestrials? Are they from our future? Who or what are they?

I bet you want to know what Barker concludes about the aliens in Part 2, don’t you?

DON’T YOU?

In my youth I held to the idea that they were truly alien visitors. Today, I still think they are alien visitors but not visitors from another planet. I am convinced they are visitors from another dimension, a spiritual dimension. I believe they are demons.

[Emphasis mine]

Now color me crazy, but I do not see how this is any less loony than the whole alien abduction thing.

What disturbs me more than the looniness above, though, is a little later on in the article. Barker bemoans the supposed lack of religiosity in the US (which is unsurprising from a fundamentalist):

Most of us are well aware that there has been a shift in worldviews in America since the 1950s. The biblical worldview that established America and sustained it for so long is losing its place in American society. Humanism, paganism, and other isms are taking center stage.

Barker then points out that many alien monster movies “prior to the 1960s” showed aliens as hostile towards humanity, wanting to destroy or conquer the world, and so forth. He complains that

… movies began to change their perspective as humanism began to permeate our society. Aliens began to be portrayed more often as not as good guys.

Given that science fiction is often social commentary about current events, I don’t find it surprising at all that there were more “aliens as good guys” stories in the 60s and continuing afterwards. It seems to me that a big message of many of these movies was that people who are different than us in some way aren’t always that bad. And, frankly, what in the heck is wrong with that idea? I was not aware that racial tolerance – what quite a few of these “good alien” movies are promoting – was un-Christian!

It’s chemistry joke day

Tuesday, July 11th, 2006

My inboxes (both online and off) have been flooded with this stuff since I got back from vacation, so I thought I’d share some it.

Here’s something my freshmen would say:

Auguste Comte, Cours de philosophie positive, 1830:

Every attempt to employ mathematical methods in the study of chemical questions must be considered profoundly irrational and contrary to the spirit of chemistry…. if mathematical analysis should ever hold a prominent place in chemistry — an aberration which is happily almost impossible — it would occasion a rapid and widespread degeneration of that science.

From the “science wars”:

Anthony Standen, Science is a sacred cow, 1958:

Chemists are, on the whole, like physicists, only ‘less so’. They don’t make quite the same wonderful mistakes, and much what they do is an art, related to cooking, instead of a true science. They have their moments, and their sources of legitimate pride. They don’t split atoms, as the physicists do. They join them together, and a very praiseworthy activity that is.

More from the “science wars”:

A physicist, biologist, and chemist were going to the see the ocean.

The physicist saw the ocean and was fascinated by the waves. He said he wanted to do some research on the fluid dynamics of the waves, walked into the ocean, and never returned.

The biologist said he wanted to do research on the organisms in the ocean and walked into the ocean. He, too, never returned.

The chemist waited for a time, pulled out his laboratory notebook, and wrote: “The physicist and the biologist are soluble in ocean water.”

You had to have had freshman chemistry:

John Desmond Baernal (Irish physicist, 1901-1971) in a Lecture at Birkbeck college, University of London, 1960:

All that glitters may not be gold, but at least it contains free electrons.

I might actually use this one in class:

My name is Bond, Ionic Bond: Taken, not shared!

As someone with degrees in analytical chemistry and chemical engineering, I feel highly qualified to appreciate this joke:

A chemical is a substance that:

  • An organic chemist turns into a foul odor.
  • An analytical chemist turns into a procedure.
  • A physical chemist turns into a straight line.
  • A biochemist turns into a helix.
  • A chemical engineer turns into a profit

Stuff to post in the lab:

Rules of the Lab:

  • If an experiment works, something has gone wrong.
  • When you don’t know what you’re doing, do it neatly.
  • Experiments must be reproducible, they should fail the same way each time.
  • First draw your curves, then plot your data.
  • To get linear data, take only two data points.
  • If you must take three data points, there is a sheet of graph paper somewhere that will make them all fall on a straight line.
  • Experience is directly proportional to equipment ruined.
  • Always keep a record of your data. It indicates that you have been working.
  • To do a lab really well, have your report done well in advance.
  • If you can’t get the answer in the usual manner, start at the answer and derive the question.
  • In case of doubt, make it sound convincing.
  • Do not believe in miracles – rely on them.
  • Teamwork is essential, it allows you to blame someone else.
  • All unmarked beakers contain fast-acting, extremely toxic poisons.
  • No experiment is a complete failure. It can always serve as a negative example.
  • Any delicate and expensive piece of glassware will break before any use can be made of it.
  • Hot glass looks just like cold glass.

Worst chemistry joke ever:

Johnny, feeling life a bore,
Drank some H2SO4.
Johnny’s father, an M.D.,
Gave him CaCO3.
Now he’s neutralized, it’s true,
But Johnny’s full of CO2.

South Carolina BBQ – Maurice’s BBQ (Santee)

Monday, July 10th, 2006

If you’ve ever heard about barbecue in South Carolina, you’ve probably heard about Maurice Bessinger and his bright yellow mustard sauce. The main Bessinger restaurant (“Piggie Park”) is in Columbia, but there are also some smaller satellite restaurants around the Columbia area and as far away as Santee, which is where you will find this particular place:

[Maurice's BBQ]
Maurice’s BBQ – just off Exit 98 on I-95

So, how is it? Can you really just pull off of the highway any time of the week and get some good barbecue – fast? We’ll see.

When we entered the restaurant, I got a bit worried. The staff was arguing about how few customers the place had. We stood in front of the register while this argument raged on – with the staff seemingly oblivious to the fact that they had customers – two of them! When the staff finally took notice (after two more customers had lined up behind the two of us), we were able to order some food.

Patty and I ordered two BBQ sandwich plates with “Big Joe” sandwiches. Prices were high. Ordering two “Big Joe” baskets will cost you as just as much as eating at a buffet like Antley’s. Our bill was about $20 including drinks. Here’s what you get with the “Big Joe” basket:

[Big Joe basket]
Big Joe basket: Fries, meteorites, and a small container of slaw

[Big Joe sandwich]
Big Joe sandwich

The “Big Joe” basket comes with fries, slaw, and meteorites. Most BBQ places don’t serve meteorites, so I assume that the dark rocklike things in our sandwich baskets are supposed to be hush puppies.

[meteorites]
Burned up on re-entry

Nope. Those are definitely meteorites, and are completely inedible. They must be included for decorative purposes only.

So how’s the sandwich? For nearly ten bucks, it’d better be large – and it is. There’s a lot of meat inside a “Big Joe” sandwich. The meat has been cooked in Maurice’s mustard sauce. There’s not much sauce in the meat. If you’re not into South Carolina mustard sauce, that’s a good thing. Me, I grew up with the stuff – so I had to pour on more sauce.

The sandwich was okay – except for the large piece of bone (or something else just as hard) in the middle. Be careful biting into a “Big Joe” – since Maurice’s BBQ isn’t very good at picking the bones out of the meat before putting it into a sandwich.

[Hunk of bone]
Imagine biting down hard on this… ouch!

What’s the verdict? Simple – go eat somewhere else. Even if you’re on tthe highway, you’ll have a better experience eating at a buffet like Lone Star (same exit as Maurice’s BBQ). You’ll pay about the same amount of money for better food.

Chemistry you can do at home: The color of money

Wednesday, June 21st, 2006

A brass is an alloy (or solution) of copper and zinc metals. Brasses have been known for a long time, and have a pleasing color – somewhat like metallic gold.

Regular pennies are made of copper metal – sometimes. Pennies made in or after 1983 aren’t entirely copper, since copper got too valuable to throw away by just making pennies with it. New pennies are actually made of zinc, with a thin copper coating (so they still look like copper pennies). This gives the pennies some rather neat chemical properties, which I’m going to post about in a few posts here on the blog.

If new pennies are made of zinc with a thin copper coating and brasses are mixtures of copper and zinc, why can’t we turn a penny into brass and give it a cool-looking "gold" finish? Well … we can. It’s quite easy to do with a new penny. (It’s even possible with an old copper penny – but you have to add the zinc yourself.)

Since a brass is a mixture of copper and zinc, we have to get the atoms of copper to mingle with the atoms of zinc. To do that, we need to get them moving. While atoms are essentially always moving, in the solid state they don’t move very much – so simply having the copper in contact with zinc is not enough to make a brass – at least not in a reasonable timeframe. (If it were that easy, then your pennies would be brass already!) We need to stir things up a bit at the atomic level, and that means we need to apply heat.

We could apply enough heat to simply melt the zinc and copper and let them mix to form a brass, but that wouldn’t be very fun. After all, we want a brass penny – not a lump of brass. So we don’t melt the penny – we heat it up gently so that the brass forms without melting the penny.

To get a nice shiny brass penny, you need to start with a nice shiny (post-1983) copper penny. Clean the penny with some steel wool, available at just about any store that sells household supplies. Buff the penny with the steel wool until it’s bright and shiny. Try to avoid buffing too hard, since you don’t want to remove the copper or scratch the penny badly.

Even if the penny is new and appears clean, buff it a little. You’re more likely to get a nice, evenly colored brassy penny that way.

Now, you’ll need a heat source, preferably one that can reach at least 200oC – same thing as 392oF. I used a hotplate with adjustable temperature settings for the pictures in this post, but you can also use a toaster oven. (A stovetop or grill could work, but it would probably be too difficult to control the temperature. Don’t even think about attempting this in a microwave oven.)

If you set your heat source to about 400oF, it will take approximately 25 to 30 minutes for your penny to become brassy. A temperature of 250oC (482oF) makes the process takes less time, but seems to produce poorer-looking results. If you’re using a small toaster oven like the one I have at my house, you might have to bump the setting to 425oF to get good results. You may also have to wait a little longer than 30 minutes. You will probably have to experiment a bit with temperature and time, but at least the raw materials are cheap!

[Hotplate at 250]

Want to see what will happen? The pictures below were taken at the 250oC temperature. The penny goes through the same color transformations at lower temperature – only more slowly.

At two minutes, you can see the penny beginning to change color and darken.

[Penny at 2 minutes]
Two minutes at 250oC

Another minute in, the penny takes on a silvery tint.

[Penny at 3 minutes]
Three minutes at 250oC

After five minutes, the penny gets a distinctive brass color.

[Penny at 5 minutes]
Five minutes at 250oC

The finished product, removed from the hotplate and cooled after about six minutes of heating. Be very careful with hot metal! It can give you a nasty burn!

[Final result]
Brass penny

Instead of a simple copper coating, the penny is now sheathed in brass. It looks a little like gold, but trying to pass off heat-treated pennies as rare gold coins is not advised!
