Janet Cooke and Jimmy's World (7/24/2011)

I was on the Metro today and a man next to me had his newspaper opened to a section about scandals in journalism. This retrospective was written due to the current phone hacking scandal in the UK. I was aware of most of the perpetrators like Jayson Blair but the earliest on the list was Janet Cooke. I just read briefly that her Pulitzer Prize had to be returned because she fabricated her story. I wanted to find out what the story was that she made up. As a reporter for the Washington Post, she had written a feature story on a boy named Jimmy who was 8 and addicted to heroin. The made up article can be found here.

The editor, Bob Woodward had sent in the piece for a Pulitzer Prize and it won. This instant fame brought on a lot more questions about Ms. Cooke and her story, "Jimmy's World." With all this pressure and questioning, Ms. Cooke confessed and her award was taken away. 

Journalism ethics (or lack of) was highlighted in the 5th season of The Wire (written by former Baltimore Sun reporter David Simon). Great show, you should check it out!

The interesting note in the article that was in the paper today was that the idea that these scandals aren't rare, what is rare is when they are discovered, the journalism industry reflects on itself and organizations redefine their own policies. I think it is harder to get away with fabrication and plagiarism these days since information sharing is a lot easier and cheaper. It's a lot easier to get caught so please just stick to the story because often real life is stranger than fiction!

Glow Sticks (7/23/2011)

Today I was playing with glow sticks and decided to learn how they glow. Glow sticks are made out of plastic tubing which encase two solutions, when mixed create a chemical reaction that produces the glow. The outer casing holds together the inner tube and the phenyl oxalate and fluorescent dye solution. The inner tube holds the hydrogen peroxide solution. When you crack the inner tube the mixing of the two solutions creates a chemical reaction in which 2 phenol molecules and a peroxyacid ester is formed. The peroxyacid ester then reacts with the dye to create carbon dioxide and dye with a heightened energy state. This energy is then dissipated in the form of releasing a photon. This photon release is what causes the glowing color you see. The color is dependent on the dye. 

Important things to remember are when glow sticks break, WASH from your skin and eyes immediately as the phenol is not good for you! So stay safe and enjoy them glow sticks! Also enjoy these photos taken having fun with glow sticks!

Septic Tanks (7/21/2011)

Today I learned how a septic tank works. So a septic tank is a system to manage waste when you aren't connected to a sewer treatment plant. The whole process works thanks to our friend gravity! As waste travels through the pipes in the home, it gets dumped into the first chamber of the septic tank. Typically a septic tank is a large concrete structure usually buried in the yard. Anaerobic bacteria in this chamber digest the waste and the solids (sludge) sink the bottom while the scum floats at the top, leaving a liquid in the middle full of nutrient chemicals! This substance is then filtered through the second chamber where aerobic bacteria break it down even more. This process creates gas (yup the smelly kind) which is vented out through pipes and the solid remains to be emptied out and the liquid goes through the drain field as it nourishes the green grass (so why exactly do we call it waste?)

I got to thinking about this after reading this post on the Good Blog:

On a related note, there is a good series that the discovery channel has on this topic, Filthy Cities: http://dsc.discovery.com/videos/filthy-cities-mass-sewage.html

Steel (7/20/2011)

Today I learned about steel. I read this quote: "Persistence is to the character of man as carbon is to steel."     -Napoleon Hill and wondered how carbon is related to steel. Turns out steel is a mix of iron and carbon. Very low amounts of carbon actually. The carbon acts as an alloy to harden the structure. Alloys change the mechanical properties of the base metal that it is mixed with.
