You just grab that brownish area by its points and you don't let go no matter what your mom says.
I get semierect proving these emails wrong. Here are two I received last year around election time.


quote:

Pull out of Iraq? Perhaps the U.S. should pull out of Chicago… Body count in the last six months:

221 killed in Iraq
292 killed (murdered) in Chicago

Chicago....Who Runs it?

Senators: Barack Obama & Dick Durbin
Representative: Jesse Jackson Jr.
Mayor: Richard M. Daley (son of Mayor Richard J. Daley)

Illinois:
Governor: Rod Blogojevich
House leader: Mike Madigan
Attorney General: Lisa Madigan, (daughter of Mike)

Leadership in Illinois.....all Democrats.
Thank you for the combat zone in Chicago.
Of course, they're all blaming each other!
Can't blame Republicans; they're aren't any!
State pension fund $44 Billion in debt, worst in country.
Cook County (Chicago) sales tax - 10.25% highest in country.
Chicago school system rated one of the worst in the country.
This is the political culture that Obama comes from, in Illinois. And he's gonna 'fix' Washington politics for us!
Wake Up America!

When I looked up the figures, Chicago had 291 murders in the first seven months of 2008, while at least 5922 people were killed in Iraq during that time (sources: Chicago Tribune and Iraq Body Count). The 221 number was American soldiers killed in Iraq during the first seven months of the year, so the original email author doesn't count non-American soldiers in Iraq as deaths.

Second email:

You can't make this stuff up. There is a little math involved here, but stay with me, it is worth it.

The official cash-for-clunkers government website where you can figure out the mileage for your clunker, and for the beautiful new car that you are thinking of getting (and having your neighbors or children or future grandchildren give you $4500 dollars to buy) is called https://www.fueleconomy.gov. Here you can select from all available cars to get some interesting energy facts and statistics about each model, including official epa mileage, estimated fuel cost per year, and yes, the dreaded carbon footprint for each car.

Let's take as an example a 2010 model Dodge Caravan minivan, one of the most popular vehicles for families with children. If you would like to follow along, please click here:
http://www.fueleconomy.gov/feg/sbs.htm

Now click on model year 2010, then Dodge, then Grand Caravan. Let's click on the 6sp 6cyl 4L model for our example. See it there? Now we get all sorts of nice numbers about that minivan. It gets a combined 20 mpg, it costs $3.05 to drive it 25 miles, and your annual fuel cost based on 15,000 miles is $1830 if gas is $2.44 per gallon. (Your mileage and gas price may vary) Pretty nice to know all that, huh?

Here is where the Obama Fuzzy Gas Math comes in. The website claims that the 2010 Dodge Grand Caravan has a 'Carbon Footprint' that will emit 9.2 tons of Carbon Dioxide annually. That's right, 9.2 TONS!!! Hmmm, that seems like an awful lot, especially if we are all going to be paying a tax on that number under the new Cap and Tax bill. Let's check the math.

Just above that claim is another number the website calls the Energy Impact Score. Our family minivan is estimated to consume 17.1 barrels of oil per year, at 42 gallons per barrel. That is about 718.2 gallons of gas per year for our 15,000 mile per year minivan family. Up above, our combined mpg estimate of 20 mpg spread over 15,000 miles is about 750 gallons. So these two estimates roughly agree with each other, and so far so good.

But wait a second, don't we remember an easy estimate for the weight of liquids we learned as a kid? A pint's a pound the world around? Remember that one? And since gasoline weighs about the same as water, can we do the math? 718 gallons x 8 pints per gallon x 1 pound per pint (use your calculator here if you like) = 5744 pounds of gasoline per year. Last time I checked, a ton = 2000 pounds. So our calculator reveals that the Caravan uses about 2.87 tons of gasoline per year as our minivan family drives it's 15,000 miles.

Hmm, but I checked again, and the website tells me that our little minivan is emitting 9.2 TONS of carbon dioxide!!! How did this happen? These auto companies are more devious than we thought. Somehow they have designed engines that can turn 2.87 tons of gas into 9.2 tons of carbon dioxide. How do they do it??

Obama Fuzzy Gas Math is how. Similar wildly inflated Carbon Footprints can be found for EVERY vehicle on this website going back 25 years. Why? Because Obama is getting ready to assign that number to every car out there, even the one sitting in your garage, and the bigger the number is, the more tax he can charge you to drive it.

Sorry about all the numbers, but somebody has to do the math.

My reply:

quote:

I’m going to make comments in the order I read this.

1) “You can’t make this stuff up.” This email just did.

2) It’s a little bit of math because you willfully distort how to do the math. More math would be involved if you did it right.

3) “2010 model Dodge Caravan minivan, one of the most popular vehicles for families with children.” – I could not find statistics for 2010 model year vehicles sold, so I’m relying on the much more unreliable method of Yahoo Autos. Even when looking under vans, the 2009 Dodge Caravan is ranked 8th this week and 7th last week in popularity with popularity measured by page views. And that’s just under vans. It’s not taking into account SUVs or sedans, both of which would be considered popular vehicles for families with children. Now, yes, popularity is measured by page views and not vehicle sales which should be the final arbiter of “popularity,” but I feel as though there is at least a mild correlation between page views and vehicle sales. Would a car that sells highly not get any page views on Yahoo Autos? My picked-out-of-the-air example shows that the 2010 Ford Focus is the most popular sedan and coupe this week on Yahoo Autos which correlates strongly with its high sales number during the Cash For Clunkers program. It’s was the most purchased car during that time in fact. The rest of the top sellers during Cash For Clunkers – the Corolla (#2), Civic (#3), Prius (#4), and Camry (#5) – all show up high on Yahoo Autos most popular vehicle lists too. So, calling the 2010 Dodge Caravan one of the most popular vehicles for families with children is most likely false.

4) Pithy sayings to the contrary, a pint is not a pound. A pint is a unit of volume. A pound is a unit of force or mass depending on how you use it in the freakin’ stupid English system.

5) The specific density aka specific gravity of gasoline ranges from 0.71 to 0.77, meaning that the density of gasoline is 71% to 77% of water. Let’s say the average is 74%. Gasoline does not weigh about the same as water.

6) A pint of water has a mass of 1.04 lbm (at 32°F), not 1.00 lbm. A pint of gasoline then has a mass of 0.77 lbm. Just changing this number in the email, the Caravan uses 4400 pounds of gasoline per year, or 2.2 tons of gasoline per year. No big deal when proving this email wrong, but it’s one more lie in this email to point out.

7) Okay, this one’s a doozy. Whoooo boy. I brought 200 pounds of wood for my fire, but there’s not 200 pounds of ash leftover. What magic took place? Probably a socialist conspiracy. Okay, enough with bad analogies. All equations are pasted in as pictures because I don’t want formatting to cause my point to be lost. The equation for burning pure gasoline (100% octane) with pure oxygen is as follows:

C8H18 + 25/2*O2 ---> 8CO2 + 9H20

If you don’t understand Chemistry, quit now. Go home and don’t take your answers from email. Every mole of octane creates 8 moles of carbon dioxide. Also note the molecular mass of octane is approximately 144 kg/kmol and the molecular mass of carbon dioxide is approximately 44 kg/kmol. Remember from above that the density of gasoline is 74% of water’s density. So let’s do unit conversions. Again, quit now if you can’t pass math. Spend more time reading text books instead of listening to Glenn Beck.

1gal C8H18 x 3.7854L/1gal x 0.74kg/1L C8H18 x 1kmol/114kg C8H18 x 8kmol C02/1kmol C8H18 x 44kg CO2/1kmol CO2 x 2.2046lbm/kg

Doing the math above shows that 1 gallon of gasoline creates 19.07 pounds of carbon dioxide using the average specific density of gasoline as 0.74. So using 718 gallons of gasoline yields, by my numbers, 13690 pounds of carbon dioxide (6.84 tons of CO2). Using the upper limit of gasoline specific density shows 14250 pounds of CO2 and 7.12 tons of CO2. This is proof that 2.87 tons of gasoline does not equal 2.87 tons of carbon dioxide as the emails implies it should in a world devoid of socialist, black boogiemen.

8) So where does the difference in CO2 between my numbers and the fueleconomy.gov numbers come from? I only accounted for the direct emissions from the car, i.e. the emissions caused only by the burning of the gasoline. The manufacturing of the car creates CO2, the extracting and refining of the gasoline creates CO2, and the transportation of all of this creates CO2. That’s not even an exhaustive list. You can take issue with the difference between the direct emissions from the car and the number quoted on fueleconomy.gov, but you cannot take issue with how one gallon of gasoline creates 19 lbms of carbon dioxide.

I had Microsoft Equations in there, but wrote it out in in text here, and there were supporting links, but I'm no good with hyperlinks here. There were some platitudes at the end I left out too. As you can see, I'm bad with analogies.
