If you haven’t read the State of the Union and the Obama-GOP Q&A, go ahead and read them now.  Otherwise, here’s the news of the past two weeks.  As usual, highlights are in red.

 


 

Politics

  • Political corruption or political gratitude? Or just politics? (Rauch)

    Consider Rep. Patricia Porker, a member of the Ways and Means Committee. She is running for re-election.

    Consider, next, Marvin Moneybags. He is a wealthy individual with interests before Ways and Means.

    Now consider two scenarios.

    1) Porker calls up Moneybags and says, “Say, Marvin. I need about $300,000 to run campaign ads, but I’m not allowed to take donations that big. I know you’d hate to see anything happen to those tax credits I’ve helped you with. Just a thought: Go spend $300,000 on ads supporting my candidacy. You won’t regret it.”

    2) Moneybags is a friend and an enthusiastic supporter of Porker’s. Acting on his own, without consulting Porker, he spends $300,000 on “Vote for Porker!” ads.

    Why is Scenario 1 illegal and Scenario 2 legal?

Way too much happens over the course of two weeks. It took me 2 hrs just to take all the links and clippings and format them >.< . But for now, here’s the news. Again, highlights are in red.

 


 

Haiti

  • Estimated death toll: 50,000 + rising. To put this into perspective, the 2004 tragic tsunami killed ~250,000 people in Indonesia (pop 240M), or about 1 in 1,000. Haiti has a population of 10M, meaning the earthquake killed about 1 in 200 (and possibly up to 1 in 50 (!))

Happy New Year, everybody! I’ve highlighted my top 3 4 reads.

 


Food

 

  • Know thy food: Beef Filler Processing (nyt)

    Mr. Roth and others in the industry had discovered that liquefying the fat and extracting the protein from the trimmings in a centrifuge resulted in a lean product that was desirable to hamburger-makers.

    The greater challenge was eliminating E. coli and salmonella, which are more prevalent in fatty trimmings than in higher grades of beef. …

    Mr. Roth eventually settled on ammonia, which had been shown to suppress spoilage. Meat is sent through pipes where it is exposed to ammonia gas, and then flash frozen and compressed — all steps that help kill pathogens, company research found.

    Untreated beef naturally contains ammonia and is typically about 6 on the pH scale, near that of rain water and milk. The Beef Products’ study that won U.S.D.A. approval used an ammonia treatment that raised the pH of the meat to as high as 10, an alkalinity well beyond the range of most foods. The company’s 2003 study cited the “potential issues surrounding the palatability of a pH-9.5 product.”

    … Beef Products acknowledged in an e-mail exchange that it was making a lower pH version, but did not specify the level or when it began selling it.

Environment

  • Packaging waste statistics

    Nearly 10% of a typical product’s price is for packaging.

    The global packaging market is worth $429 billion.

    Nearly 1/3 of Americans’ waste is packaging. Just 43% is recycled after use.

    In 2007, Americans threw away 78.5 million tons of packaging—520 pounds per person. That’s a 71% increase from 1960.

    A 2008 bill written by Rep. Anthony Weiner (D-N.Y.) would have required the EPA to find ways to reduce packaging waste by 30% in a decade. It died with no cosponsors.

  • China’s role in killing the Copenhagen deal.

Society

  • Journey into Whitopia
  • The World’s Hardest Language (economist)
  • Cell phone usage patterns across various cultures (economist)

    The best way to grasp Japan’s mobile culture is to take a crowded commuter train. There are plenty of signs advising you not to use your phone. Every few minutes announcements are made to the same effect. If you do take a call, you risk more than disapproving gazes. Passengers may appeal to a guard who will quietly but firmly explain: “dame desu”—it’s not allowed. Some studies suggest that talking on a mobile phone on a train is seen as worse than in a theatre. Instead, hushed passengers type away on their handsets or read mobile-phone novels (written Japanese allows more information to be displayed on a small screen than languages that use the Roman alphabet).

  • Spanking vs not-spanking

    What she discovered was another shocker: those who’d been spanked just when they were young—ages 2 to 6—were doing a little better as teenagers than those who’d never been spanked. On almost every measure.

  • Life as a quadrapalegic: Tony Judt

    There is no saving grace in being confined to an iron suit, cold and unforgiving. The pleasures of mental agility are much overstated, inevitably—as it now appears to me—by those not exclusively dependent upon them. Much the same can be said of well-meaning encouragements to find nonphysical compensations for physical inadequacy. That way lies futility. Loss is loss, and nothing is gained by calling it by a nicer name. My nights are intriguing; but I could do without them.

  • Jeremy Lin: The ABC basketballer (time)

    It’s been 64 years since the Crimson appeared in the NCAA tournament. But thanks to senior guard Jeremy Lin, that streak could end this year. Lin, who tops Harvard in points (18.1 per game), rebounds (5.3), assists (4.5) and steals (2.7), has led the team to a 9-3 record, its best start in a quarter century.

    Less than 0.5% of men’s Division 1 basketball players are Asian-American.

Development

Economy

  • Food stamp usage in the recession
  • 10 principles of economics
  • Sweden’s eco-vangelism

    There’s even an official name for the Stokeses, along with three other households in Northern Virginia: They are Climate Pilots, guinea pigs in a Swedish experiment aimed at helping U.S. citizens understand that a lifestyle that curbs greenhouse-gas emissions is not necessarily oppressive, just different. Whether Americans are willing to follow their example is part of the political calculation lawmakers have to make as they consider imposing nationwide limits on emissions in legislation making its way through Congress.

  • The Finance Committee: How Wall St Wins on the Hill (HuffPo)

    The question was simple: Should the lending practices of auto dealers be regulated?

    The clerk called the roll, starting from the top. Senior Democrats roundly rejected Campbell’s amendment. It appeared as if the Democrats would beat back the effort and apply the same standard to car dealers that was applied to everyone else.

    Then came the bottom two rows, the place where reform goes to die. Despite the disapproval of the powerful chairman and nearly every consumer group in the country, the Campbell amendment passed by a 47-21 margin.

  • Food Stamps Usage Soars (nov) (dec) (nyt)

    Now nearly 12 percent of Americans receive aid — 28 percent of blacks, 15 percent of Latinos and 8 percent of whites. Benefits average about $130 a month for each person in the household, but vary with shelter and child care costs.

Healthcare

  • Relative magnitudes: they’re important. (medical)

    But in the case of anticancer drugs, a phenomenon known as omission bias appears to be at work. People tend to worry more about a low risk of harm from something they do (like taking a pill or a vaccine) than about a higher risk of harm from doing nothing.

    In a seminal 1994 study of vaccination trends for whooping cough, researchers from the University of Pennsylvania found that parents gave far more credence to hypothetical concerns about side effects than about the very real danger of an unvaccinated child’s becoming severely ill with the disease.

  • A primer on the problems with healthcare and one solution proposal (Atlantic)

    A wasteful insurance system; distorted incentives; a bias toward treatment; moral hazard; hidden costs and a lack of transparency; curbed competition; service to the wrong customer. These are the problems at the foundation of our health-care system, resulting in a slow rot and requiring more and more money just to keep the system from collapsing.

  • Wow, what a deal! $15 for 700 Placebos!

    There are a lot of spoof sites about placebos out there. This isn’t one of them! We actually sell placebos. Just click on the Buy Placebos button.

    We make absolutely no therapeutic claims for our placebos – they are made of sugar; they are not drugs – but we offer them, with love and with a sense of fun, as triggers and inspiration for the placebo effect.

What is Materials Science?

Friday, December 11th, 2009

Being a Materials Scientist, I get this question a lot. And I hate getting this question because the answer is exceedingly obvious, but also exceedingly vague.

 

Allow me to illustrate with a brief excerpt from a representative (though fictional) conversation that I’ve had with basically every non-materials scientist I’ve ever had to make small talk with. (And if you’ve missed out, just let me know, and I’ll be sure to let you experience the awkwardness first hand)

 

“Hi Harold, I’m Colleen, pleasure to meet you.”

 

“Hi Colleen, uh…nice to meet you too. Um…so what is it that brings you to Chicago?”

 

“Well, I moved here about a couple of years ago, and I’m here on a public health fellowship to try to improve nutrition and reduce the incidence of obesity in the poorer neighborhoods of Chicago.”

 

“Oh wow. That’s really awesome. How do you like it?”

 

“It’s good. Pretty rough having to deal with red tape and Chicago bureaucrats, but there’s a huge need in these communities for better dietary education and access to good food, so I love it. How about you, what’re you doing in Chicago?”

 

“I’m a grad student in materials science at Northwestern.”

 

“Oh cool… What is materials science, exactly…?”

 

“Uh…materials science is the…study of materials…”

 

“Oh, um…that…sounds…neat?”

 

See!? Obvious answer = Totally non-descript.

 

Part of the problem is that Materials Science is a _huge_ field. It’s pretty hard to describe in just one sentence. The other is that outside of materials scientists, no one uses the term “materials science” to describe what are basically materials science research fields. Instead, you hear about specific areas of materials science such as “nanotechnology” or “solar cells”. And finally, well, the statement _is_ pretty vague.

 

Some people like to use “Materials Science is the study of ’stuff’ “, but replacing one vague word (”materials”) with an even vaguer one (”stuff”) doesn’t exactly serve to clarify matters.

 

However, I think I’ve come up with a slightly better (if still incredibly vague) one-line definition.

 

“Materials Science is the study of the ’stuff’ that the objects around you are made of”

 

So what do you think? Does that make slightly more sense? It doesn’t roll off the tongue particularly well, ** but I think the extra time required to say it gives the listener the chance to parse through all the vagaries. (It’s FEATURE, not a bug!)

 

If it does, here’s a little quiz.

 

What is it about the following objects, that a materials scientist would be interested in?

 

1) Tennis racquets
2) Automobiles
3) Laptops
4) Medicines
5) Fuel cells

 

** “Materials Science is the study of the ’stuff’ that other ’stuff’ is made of” is a bit more pithy and has alliterative appeal, but keep the two ’stuff’s straight can be a bit tricky, particularly if the listener has been imbibing a bit.

 

** Why not just “Materials Science is the study of what the world is made of?” Because, while “what things are made of” is indeed an interesting question, there’s much more to a materials science than just identification. Just wait and see…

I’m going to try really hard to not constantly linkspam. However, I come across way too many things worth reading/watching, so you’ll probably be subjected to these linkdumps on a somewhat regular basis. I’m also always looking for new perspectives or new topics, so if you come across anything interesting, please send it my way. Hope you enjoy =)
