Oxygen is one of the most fascinating elements for many reasons.  Before we get to it, I first want to point out that the column of the periodic table that starts with nitrogen are called pnictogens, whislt the column starting with oxygen are called chalcogens.  The term pnictogen is recent, dating form the 1950s.  It comes from the Greek plural noun pnikta which means something on the order of “those that are suffocated” in reference to the fact that nitrogen will not support life.  The “gen” part is from the Greek gonos, “born” or “generated”.

Chalcogen comes from the ancient Greek chalkos, meaning “ore” and gonos, and in fact an extremely large number of metal ores contain oxygen or sulfur of both.  Selenium and tellurium are chalcogens that are often found in gold and silver ores.

Time before last we discussed nitrogen and molecular orbital diagrams for it.  If you are not hip to MO diagrams, I suggest you read that part of the link before you try to tackle the MO diagrams for oxygen.

September 2 is the 245th day of the year (246th in leap years) in the Gregorian calendar. There are 120 days remaining until the end of the year.

On this day in 1969, America’s first automatic teller machine (ATM) makes its public debut, dispensing cash to customers at Chemical Bank in Rockville Center, New York. ATMs went on to revolutionize the banking industry, eliminating the need to visit a bank to conduct basic financial transactions. By the 1980s, these money machines had become widely popular and handled many of the functions previously performed by human tellers, such as check deposits and money transfers between accounts. Today, ATMs are as indispensable to most people as cell phones and e-mail.

Several inventors worked on early versions of a cash-dispensing machine, but Don Wetzel, an executive at Docutel, a Dallas company that developed automated baggage-handling equipment, is generally credited as coming up with the idea for the modern ATM. Wetzel reportedly conceived of the concept while waiting on line at a bank. The ATM that debuted in New York in 1969 was only able to give out cash, but in 1971, an ATM that could handle multiple functions, including providing customers’ account balances, was introduced.

ATMs eventually expanded beyond the confines of banks and today can be found everywhere from gas stations to convenience stores to cruise ships. There is even an ATM at McMurdo Station in Antarctica. Non-banks lease the machines (so-called “off premise” ATMs) or own them outright.

It’s the last holiday weekend of Summer and what better way to celebrate than with a backyard Clambake. So what’s for desert? S’mores are passe but who doesn’t love chocolate and peanut butter. Peanut Butter & Chocolate Lover’s Trifle is really easy to put together with a minimum amount of cooking. It does require a large serving bowl, preferably glass so guests can see the luscious layers.

Peanut Butter & Chocolate Lover’s Trifle

Ingredients:

Either a box of brownie mix, or a homemade batch of brownies. You can also use chocolate cake. Store made is a quick substitute

Whipped cream, about two cups. Canned (use the heavy cream version) or homemade.

Peanut butter sauce (melt one 10 ounce package of peanut butter chips with 1/4 cup of milk, 1/2 cup of heavy cream and 1/4 tsp of vanilla over low heat until combined, let cool).

Reese’s peanut butter cups, chopped

Kit Kat bars, chopped or Reese’s Pieces

2 packages of instant vanilla pudding made according to their directions.

Directions:

Layer the bottom with broken up brownies or cake. Top with vanilla pudding, peanut butter sauce, Reese’s peanut butter cups & Kit Kat bars or Reese’s Pieces, and a layer of whipped cream. Continue building your trifle with these layers until you’ve run out of ingredients or room 🙂

Kari Goodwin who created this recipe for her blog, Minute on the Lips didn’t post how many chocolate lovers this recipe would serve but there was plenty for 8 guests with left overs. As for calories per serving, if you need to ask you probably shouldn’t be eating this. But hey, it’s a holiday, take an extra lap around the track for the next week.

What we have learned this week is discussed with Up with Chris Hayes guests Josh Barro (@jbarro), writes Bloomberg View‘s “The Ticker“; David Sirota, (@davidsirota) writes a nationally syndicated weekly newspaper column and hosts a radio show, “The Rundown with Sirota and Brown“; Ana Marie Cox (@anamariecox), columnist for “The Guardian” and founder of the political blog Wonkette; and Bob Herbert (@bobherbert), distinguished senior fellow at Demos and former New York Times columnist.

During the RNC Convention, Republican Presidential nominee Mitt Romney partied with millionaire and billionaire donors on a yacht registered in the Cayman Islands.

South Carolina Republican Senator Lindsey Graham told the Washington Post: “The demographics race, we’re losing badly ….

We’re not generating enough angry white guys to stay in business for the long term“

90% of the GOP is white.

Projected US White Population in 2050: 50.1%

NBC/WSJ Poll: Romney has 0 % Of African-American Vote.

Only 2% of the delegates at the RNC Convention were Black.

Federal judges are overturning controversial laws passed by Republican controlled states that discriminate against minority and disenfranchised voting rights.

Texas: Court rejects Texas legislative districts as discriminatory

Federal court overturns Texas law requiring voters to show photo ID

Texas is appealing both of these rulings.

Florida: Federal Court Blocks Florida Early Voting Restrictions

Ohio: Federal court overturns Ohio early voting restrictions

We now know what a gay bar at the RNC Convention looks like: It’s hard to tell who is gay or straight since they’re all dressed like Alex B. Keaton; what really identified it as a Republican Gay Bar was the Go-Go dancers were all wearing t-shirts and long pants.

Oy.
