Hitler Firing Off

I found this image all over. Anyone know who made it?

Thanks to recent politics, I've been seeing the same myth cropping up over and over. There are several different versions, but each one has the same central core: that part of Adolf Hitler's control of Nazi Germany rested on the fact that he managed to take the guns away from the German people. 

So did he?

Well. No. He didn't. In fact, he did the opposite.

Sir Beef

Wikipedia says this is a sirloin. I'll have to take their word for it.

I heard this one the other day and I had to rush home and look it up, because I'd never heard it before. To be fair, that may be because I don't really know a lot about meat or preparing it (not something I do much, being unable to digest it).

What is this myth? That the cut of beef called sirloin got its name because an English king once knighted a piece of meat and called it "Sir loin."

Sadly, as cute as the story is, it's not at all true. 

It's French. "Sir Loin" is actually "sur longe" ... Longe was French for loin, and sur simply means "above." So it is literally the cut "above the loin." *

Where is that? Well, that depends on where you live.

If you're American, it's this lime green spot:


If you're British, it's practically a quarter of the cow:


If you're Dutch, it's this long peach colored area:


And if you're Brazilian, it's a slim area between the tenderloin and it's skirt (and your cows have this funny hump too):

Doomsday 2012

It's that one that everybody knows, but nobody will quite admit to believing -- that the world is going to end on 21 December 2012. 

The usual story is that it's because of some Mayan Prophecy and an asteroid hitting the earth. Or the magnetic poles flipping. Or the sun going supernova and flame broiling all life on earth. Or something.

So what's it all about?

Usually it's seen with something that looks like this:



But that's not even Mayan -- it's the Aztec "Stone of the Sun". You've got to take anything with a grain of salt when they can't even get the culture right for their pictograph proof.

Pilgrims

I suspect that with the USian Thanksgiving right around the corner, there's going to be talk and pictures of the Pilgrims.

For those who don't know what I'm talking about, here's a quick rundown of the usual story: Thanksgiving (AKA "Turkey Day") is an American holiday which is a feast of Thanksgiving, given in remembrance of the First Thanksgiving where the Pilgrims had a big feast to celebrate not starving to death though their first winter in America. It's traditionally celebrated with eating of turkey, cranberries, and pumpkin pie (traditionally "pilgrim food") and pictures of people who look like this:


Because Black, White, and Buckles were totally the style in 1620.

I'm not tackling Thanksgiving today (maybe a little closer to the actual holiday) but let's talk about the Pilgrims! Common ideas include:

1) They dressed.. well, like Pilgrims.

2) They landed at Plymouth Rock.

3) They can also be called "Puritans."

....

I'm afraid, as per the usual, we're 0 for 3 for actual facts in that list.

Pens In Space

Gotten from Tumblr. Source hidden to protect the guilty.

This is one that seems to be making the internet rounds lately. 

American astronauts actually started off using pencils when they first went into space. But they quickly realized that the higher oxygen content in the capsule make the highly flammable carbon in the graphite of the pencil even more... flammable. Which isn't really a good thing.

The tip of the pencils would also break off and float though the cabin. This was more than just a small hazard from potentially inhaling a small piece of sharp graphite -- the bits of pencil got into the equipment and caused shorts. 

NASA didn't actually invest any money into the Space Pen -- it was done by Paul C. Fisher, with his own money.* He was successful, creating the Fisher Space Pen used today by both the Americans and the Russians. ** He sold his pens to the Space Agencies for $2.95 apiece

Cleo Myths



Cleopatra is one of the most famous women in the historical record. Pretty much everyone recognizes her name, and is usually able to spout of some information they've heard about her. 

1) She was an Egyptian Queen.
2) She had two husbands/lovers -- Julius Caesar and Mark Anthony.
3) She was black.

Let's see... that's a quasi right, a nope, and a.... nope.

Enstein's Math Fails


As a child I believed that math was the study of what, exactly, it takes to break the hearts, minds, and souls of children.

 It nearly killed me to get though Math 111 in University. Never have I studied so hard for a B... and I say that as someone who took a medieval French literature class in French. (In complete honesty, I'm not that bad at math, I just have severe text anxiety and all of my math classes were graded entirely via exam performance.)

So I always derived some comfort from the fact that Albert Einstein had also struggled in math at school. This was, in my young opinion, proof of how messed up the school curriculum of judging one's ability to do something in a high stress environment (and the dreaded "answer as many questions as you can in 5 minutes" mini-quiz torture). His failure was my validation that math as it was taught in school was utterly useless.

You can imagine my disappointment when I learned that Einstein had never actually had any problems with math in school.

Growing Though the Ages

Let's face it. Everybody knows that everyone who lived before us was shorter than the current generation. People get a little torn on if you ask them if we-the-living-right-now have maxed out on that height, or if the next generation to come is going to be even taller than we are, but pretty much everyone agrees that people who lived 100 years ago would be dwarfed by our current towering stature. 


We'll just have to use the late He Pingping (left) and the still-with-us Sultan Kosen (right) for an example of what it would look like if an average man today were to meet his great-great-great-great grandfather's grandfather. 

But it's obvious people before were shorter. Just look at their short little beds and low ceilings in their houses!

Sadly, such things lie.

Pontiff Ponderings



This one comes up pretty much any time someone finds out that I spent a lot of time studying the Medieval period when I was getting my degree. The conversation usually goes something along the lines of, "Oh, you studied Medieval church politics. Did they cover Pope Joan?" *smirk* *wink wink* You know, because we only studied *Catholic Church Approved* history at my... secular... state... university. 

For those of you who haven't heard of this one (it seems to be favored in the "I watch Game of Thrones so now I'm a Medievalist crowd" {no offense to the people who like Game of Thrones, but it's not exactly a shining example of Middle Ages accuracy}), Pope Joan is supposed to be a woman who managed to hide her sex and reign as Pope for a period of a little over 2 years. But she got pregnant and delivered a baby in the middle of a parade of some sort and then was stoned to death by the crowd. Or something like that, there are a few variations of the tale. 

The story often goes on to elaborate that the entire world has covered up her existence conspiracy-style because it would be embarrassing to the Catholic Church to admit her existence, so it's a secret known by a select few and the person I'm talking to just happen to be one of the few in the know. 

*facepalm*

Shakespeare's pen


Cobbe Portrait of William Shakespeare

This one I don’t even. It’s come up a couple times and I’m still baffled every time it comes up. Most mythbeliefs I can kind of see the quasi-logic behind, but with this one I really can’t.

So what is this mythtory? That William Shakespeare didn’t write Shakespeare’s plays. Edward de Vere is the usual “true” author given when pressed for an alternate author, but I’ve seen other names tossed out as well, like Christopher Marlowe.

So did Shakespeare write Shakespeare?

Leaps of 1929


Panic of 1907, Outside U. S. Subtreasury building at Wall and Broad St. in October 1907

The Great Depression wasn't the first depression for the US economy, but it's certainly the best known. The most famous story is that on Black Tuesday, 29 October, 1929, that stock investors, realizing that they were financially ruined, threw themselves from their office windows down to the pavement below. 

I was taught in high school that when the stock investors realized that they'd lost so much money they'd never be able to get out of the debt, they jumped from the windows of their high office buildings 

It wasn't even 100 years ago, so how wrong could it be?

This Pancake Earth




The Flat Earth Society gets all the cool flat-earth-in-space pictures.

SING WITH ME, EVERYBODY!

(The tune is supposed to be the same as “Old MacDonald Had a Farm”  but I’ve found it’s more amusing to just pick your favorite melody)

Columbus sailed the ocean blue in 1492.
Columbus sailed the ocean blue in 1492.
With three tall ships, 120 men,
Sailing on, sailing on, sailing on, on, on, on --
Columbus sailed the ocean blue in 1492.

He proved the earth was round, not flat, in 1492.
He proved the earth was round, not flat, in 1492.
With three tall ships, 120 men,
Sailing on, sailing on, sailing on, on, on, on --
He proved the earth was round, not flat in 1492.

This entry isn’t actually about Columbus (though I’m sure I’ll get to him eventually), this entry is about how everyone knows that when Columbus sailed that ocean blue, everyone thought he’d fall off the other side – because EVERYONE knew the earth was flat.

I mean, just look this totally ancient rendition of the earth:

Engraving: L'atmosphère: météorologie populaire

That’s from all the way back in the ancient days of… 1888.

The Height of Napoleon




Jack of All Trades -- providing amusingly incorrect history since the year 2000


Let’s face it; everyone knows that Napoleon wasn’t exactly at towering example of height. One might even say he had a Napoleon complex because of his short stature.

I mean, just look at this contemporary 1850 image of him:

James Gillray: The Plumb-Pudding in Danger;–or–State Epicures Taking un Petit Souper, 1805
Metropolitan Museum of Art

It’s not like the British, his mortal enemy, would make stuff up about him, right?
