Meme, Too!
Jennifer has started the great pop-sci book project, a natural evolution (and yet intelligently designed progression) of The Big Read
The rules are familiar
1. Highlight those you’ve read in full
2. Asterisk those you intend to read
3. Add any additional popular science books you think belong on the list
4. Link back to me (leave links or suggested additions in the comments, if you prefer) so I can keep track of everyone’s additions. Then we can compile it all into one giant “Top 100” popular science books list, with room for honorable mentions. (I, for one, have some quirky choices in the list below.) Voila! We’ll have awesome resource for general readers interested in delving into the fascinating world of science!
I don’t read tremendous amount of pop-sci, and not much in physics since A Brief History of Time, as I’ve gone to grad school since then and really don’t need much prose on how weird quantum mechanics and relativity are. (I had to put my foot down on getting pop-sci books as gifts after getting a pop-up book of cosmology; I felt a bit like John Cleese in a Monty Python sketch
Do you like your rattle? Do you like your rattle?
Ah, yes, the rattle.
Ooh, he’s talkin’ already
Of course I can talk, I’m the Minister for Overseas Development
But I digress.)

Hopscotch in the Minefield
Teaching evolution — and, by the sound of it, doing a good job — in Florida. He realizes that if the science sounds dogmatic he’s lost before he even starts.
A Teacher on the Front Line as Faith and Science Clash
When Florida’s last set of science standards came out in 1996, soon after Mr. Campbell took the teaching job at Ridgeview, he studied them in disbelief. Though they included the concept that biological “changes over time” occur, the word evolution was not mentioned.
He called his district science supervisor. “Is this really what they want us to teach for the next 10 years?” he demanded.
In 2000, when the independent Thomas B. Fordham Foundation evaluated the evolution education standards of all 50 states, Florida was among 12 to receive a grade of F. (Kansas, which drew international attention in 1999 for deleting all mention of evolution and later embracing supernatural theories, received an F-minus.)

What's the Rolls Royce of Chemistry?
Disciplines of chemistry as retail chains. The IKEA of Chemistry
Total Synthesis- The Wal-Mart of Chemistry. Okay, before I alienate my tot. syn. friends with this one, let’s think about it. Typically, when modern reactions are developed, they are almost immediately put to task in syntheses of natural products, as proof of their usefulness. People go to natural products in a pinch, typically cause they have nowhere else to go. Much like Wal-Mart. Both Wal-Mart and total synthesis labs are open 24 hours. Also, both have gathered quite a bit of controversy in their exploitation of labor…

The Periodic Table of Comic Books
Click on an element, and find a listing of some comic books in which that element was used/mentioned, with scans of the pages.
I was previously unaware that there was a Ricky Nelson comic, nor that he claimed to be fascinated with the subject of the atomic world and nuclear fission. Too bad he didn’t know a proton from a protein.
This comic book is an obvious attempt to cash in on Ricky Nelson’s immense popularity in the late 1950’s. His All-American image was cultivated and his musical career was nurtured in the Nelson family television situation comedy, The Adventures of Ozzie and Harriet, which ran on the ABC Television Network from 1952 until 1966.
Practical, but not Practical
The practical joke arms race of Caltech, MIT and … UBC? Extreme Engineering
In this arms race, UBC is the third superpower. One of its most sophisticated feats also took place on the Lions Gate Bridge, in 1988. Electrical engineer Johan Thornton, now a contract engineer in his late 30s, decided that he wanted to make the bridge lights —all of them—blink. Thornton will only broadly describe the hack, but he hints that the low current of the bridge’s daylight sensor was crucial. For hours, people assumed that the blinking bridge lights were broken. Then the crew of a passing cargo ship reported that the pattern was Morse code: “UBC engineers do it again.”
I had no idea. I spent two and a half years at TRIUMF, on the edge of the UBC campus, but don’t recall hearing about any adventures in my time there.

Using NMR to check the fitness of wines (Don’t bother with this, for multiple reasons, if they have a bottlecap instead of a cork)
Nuclear Magnetic Resonance Spectroscopy Makes Sure Wine is Fit For the Queen of England
When wine hits 1.4 grams of acetic acid per liter it is considered bad. Although the average bottle of vinegar has around 12.50 grams acetic acid per liter the difference is nothing to take lightly. NMR measures acetic acid in wine down to the tenth of a gram.
Up to 10 percent of wine spoilage comes from the oxygen-alcohol blend. Cork taint, from the 2, 4, 6-tricloroanisol molecule accounts for the other main contributor of wine spoilage. Though NMR is only used in locating oxidation based spoilage, it is still a major breakthrough in the wine world, especially when it comes to auctions.
Auctioneers say as many as 50 percent of the vintages pre-1950 auctioned at places like Christie’s or Zachy’s, where $2000 bottles are the norm, are spoiled. Augustine says that when it comes to exquisite wine the importance of protecting the investment is up to an individual.
And Tyler Colman asks, “Why use a cork in the first place?” when dealing with wines that are a little lower in cost.
Although some sommeliers may scoff at wine from a plastic spigot, boxes are perfect for table wines that don’t need to age, which is to say, all but a relative handful of the top wines from around the world. What’s more, boxed wine is superior to glass bottle storage in resolving that age-old problem of not being able to finish a bottle in one sitting. Once open, a box preserves wine for about four weeks compared with only a day or two for a bottle. Boxed wine may be short on charm, but it is long on practicality.
He Helps Us Get High
August 18, 1868. Jules Janssen “invents” helium. (At least, according to principal Skinner. “Curse the man who invented helium! Curse Pierre Jules César Janssen!)
Janssen was observing an eclipse and measured an emission line with a wavelength of 587.49 nm, which didn’t correspond to any known element. Norman Lockyer also observed the line later that year, and as it could not be reproduced in the lab, proposed that it was a new element, which was named after helios, the sun.
