Snap Judgment #32: No Stompies in Germany

Snapple Fact #1366: In Denmark, citizens have to select baby names from a list of 7,000 government-approved names.

Verdict: True

So as it turns out, many countries have specific laws as to what you can and can't name your kids. Some are pretty obvious, such as no slurs or generally offensive names, but the laws get a lot more interesting as you dive in a little deeper. Denmark, as it turns out, is just particularly strict, while many countries vary pretty wildly. 

Let's start with the initial subject of this Snapple "real fact" - Denmark. Denmark does indeed have a list of approximately 7,000 government-approved names. One can apply for special permission through their local church, then the government reviews it. They are so strict that they actually reject 15-20% of submitted names. A few banned names: Anus, Pluto, and Monkey. 

According to the earlier linked Mental Floss article, here are a few rules of note:

  • Names must indicate gender 
  • Creative spellings of approved names are largely not allowed
  • Last names can't be used as first names and vice versa
  • Part of the rationale is to protect "rare Danish last names"

In 1982, Sweden enacted the "Naming Law," which was originally designed "to prevent non-noble families from giving their children noble names," but it has since evolved. First names can't be offensive or "cause discomfort" for the individual bearing it, you can only change your name once, and you must keep at least one of the original names you were given if you do change your name. A few banned names: Metallica, Superman, Veranda, Ikea, and Elvis. Interestingly enough, they specifically allow "Goole" as a middle name, and Lego is an approved name. 

The US has its own federal naming laws, but it also varies wildly from state to state. Some states ban obscenities, some states (such as Kentucky) have no name laws at all, and in some cases, courts interpret the right to name a child whatever the parents' want as a matter of Free Speech (1st amendment clause) and Due Process (14th amendment clause). California actually doesn't allow for diacritical marks (ex. José, Noël), and some states limit the number of letters a name can have for record-keeping purposes. 

To close it out, here's an article from Business Insider that lists some interesting banned names by country! Enjoy, and if you live in Germany, do not name your kid "Stompie."

Snap Judgment #26: This Radiation is Bananas

#1282: “EATING 600 BANANAS IS THE EQUIVALENT OF ONE CHEST X-RAYM IN TERMS OF RADIATION.”

Screen Shot 2018-03-15 at 2.57.55 PM.jpg

Verdict: False

Many of you must have heard some form of bananas being radioactive. This is in fact true. Bananas contain a radioactive element called potassium-40, which is not as scary as it sounds. The 40 attached to the name is because it is an isotope. By nature, an atom of any element must have an exact number of protons to be that element. However, the element can have a varying number of neutrons, changing its mass, hence the number at the end of the name (19 protons + 21 neutrons = 40). This can cause instability, and the atom needs to sweat off that excess energy either by releasing an electron, neutron, or proton (this case changes the element to a different one). This is what most know as radiation. So, is this case of radiation dangerous? Absolutely not.  Take a look at yourself. Yes, you. You’re “radioactive” because the human body contains potassium, and the odds are stacked in favor of some of that potassium being potassium-40, so you can bet you have some excess electrons or neutrons or protons pew-pewing around in and out of you.

So, bananas. Turns out it’s just funny because they’re bananas. So much so that in the mid- nineties, an unofficial “Banana Equivalent Dose (BED)” measurement system for radiation emerged. Let’s stick with a better metric, though. Here is a chart from the XKCD guy, listing radiation does in Sieverts. I’ll include a link to the original image since it’s easier to read and very much worth the read.

https://xkcd.com/radiation/

Goddamn this guy sources well. Anyways, here we see a banana is equivalent to exposure of 0.1 microsieverts. A chest x-ray is 20 microsieverts. Let’s do the math. 20/0.1 = 200

Nope.

Snap Judgment #23: Happy birthday, you're not special!

#74: You share your birthday with at least 9 million other people in the world.

Verdict: False on a technicality

Let's open with why it says "False on a technicality." Really...that means false, but I'm giving them just a few points (JUST a few) for making a simple mistake. According to ThoughtCo, the odds of you sharing your birthday with anyone should be approximately 1/365 in any population (0.274%). This assumes ~7 billion people at time of article (though it's more accurately around 7.6 billion). Since we now know you share it with .274% of the population, we do the math (.274% of ~7billion): you share your birthday with over 19 million people around the world (19,178,082). So this means that yes, technically Snapple was right saying you shared with over 9 million people (even if it was understated), right? WRONG. Leap Year, yo! 

If you are born on February 29th, you should share your birthday with 1/1461 of the population (0.068%). That means you share your birthday with 4,791,239 people, making Snapple officially wrong. Now this was a fun but short math adventure accented with pedantry and literal interpretations, so I wanted to add a little something extra to the topic. I went ahead and researched some of the most and least popular birthdays. 

Fun Fact: September is the most popular birthday with Winter being the least popular as a whole (Dec-Feb).

Researchers at Harvard University examined births between 1973 and 1999, and found that the most common birth date for those years was Sept. 16 (2006 report), but more recently, Matt Stiles at The Daily Viz created a visualization based on data FiveThirtyEight compiled on births from 1994 to 2014, updating that to Sept. 9th. The data is from the National Center for Health Statistics and the Social Security Administration.

So there you have it. A short one, but we love finding ones where we get to be SUPER petty about why they are wrong, so we couldn't resist. Ok, not "we," me. 

Cheers,
Greg

Snap Judgment #22: Polar Assassins

#726: A polar bear cannot be seen by an infrared camera, due to its transparent fur

Verdict: False (technically)

So this one is fun because 1. it's not that crazy when broken down, 2. the images are kind of funny, and 3. it's just overall neat-o. According to Now I Know, scientists were attempting to get a headcount on the number of polar bears in the Arctic, especially since they were hunted up through most of the 20th century. While their natural camouflage can make it tricky, obviously there are a number of devices we can and do use to capture images.

Turns out, due to the many layers of fur and fat trapping body heat very efficiently and "well below skin level," heat-detecting devices such as infrared are rendered all but completely useless. This is why I rated it this "Real Fact" as "false." The translucent nature of their fur (which is accurate) is not the reason they do not show up very well in infrared, but rather it's because the outer layers of their skin are about the same temperature as the air around them. Their face and breath can be reasonably detected, but according to the article, "that isn't enough to go on." Ultimately they've had to settle for tranquilizing and tagging each one individually (can't pay me enough to do that). Side note: Now I Know comes in newsletter form. I've been getting it for probably 5+ years now. Dan does great work so you should definitely consider signing up for it!

A few more tidbits about their ability to stay warm (in -40°C no less). They keep their internal body temperature at around 37°C with their distinct fur coat. It is made up of two main layers: a short and dense "underfur" beneath the skin and an outer layer made of translucent, long, coarse hairs. The translucent hair scatters light which is why it appears white to us.

Snap Judgment #21: Shrimp Pistoleros

#770: Pistol shrimp can make a noise loud enough to break glass.

Image Source

Verdict: True. 

Confession time: I knew this was true because I already knew a tiny bit about these totally awesome aquatic sharp shooters. I just REALLY wanted to share facts and videos about this ridiculous creature. A "pistol shrimp" gets its name from the massive claw it uses to "shoot" other creatures. So let's dive into what exactly this "pistol" is by starting with good ol' Wikipedia page on "pistol shrimp" or "alpheidae" (Quick note: there is literally over a thousand different species of "snapping shrimp," many of which have this "pistol shot" for subduing prey):

Alpheidae is a family of caridean snapping shrimp characterized by having asymmetrical claws, the larger of which is typically capable of producing a loud snapping sound. Other common names for animals in the group are pistol shrimp or alpheid shrimp.

That "snapping" characterization is a serious understatement. According to the previously linked BBC video, the "flash point" of the snap heats up the area - for a split second - to 4000°C. That is not a typo. This super-heated "bubble bullet" can travel as fast as a car and often literally launches their prey several inches (which for a 3-5cm creature underwater is no small feat). In addition to being a tool of brutal fishy murder, according to the BBC, it is also their primary source of communication "with their innumerable neighbors, each tucked away in it its own den in the soft sand." The sound is so loud, that it has become a staple "noise" under the ocean and is often, according to the same BBC article, described as "snaps" underwater or like the "cracks" of burning tinder.

So a fun thing I stumbled across in the above mentioned BBC article: 

Between 1944 and 1945, the US Navy deliberately used snapping shrimp colonies as an "acoustic screen" to hide from the underwater hydrophones in Japan's harbours, allowing their submarines to enter undetected. The shrimp might even have had their own part in early atom bomb tests on Bikini Atoll.

Basically, they are so loud and so prevalent that the military used them to as a "noise cover" on multiple occasions. 

So there you have it. These little desperados are awesome. Have a good rest of your week and (an early) Happy Mardi Gras!

Snap Judgment #6: Dolphins like to think their &*%$ don't Stink

#970: DOLPHINS ARE UNABLE TO SMELL

Ecco.jpg

Verdict: True

This is a pretty short one mostly because it's true - that being said, there are some interesting extra elements to this, as is generally the case with the "Real Facts" we choose from Snapple's list. According to Whale Facts, this is true, despite the fact that dolphins do appear to have olfactory tracts during fetal development. There seem to be no olfactory nerves, however, meaning it is functionally useless. 

What I found interesting was the relationship between their sight and echolocation. For those who are not aware, dolphins use echolocation - similar to bats - under water. Many (if not most) animals that use echolocation have very poor eye sight, but this is not the case with dolphins. What isn't clear (at least in my research) is how good their eyesight actually is.

The above article from Whale Facts claims that dolphins have particularly acute vision, while this Business Insider piece diving into the various testing (really interesting) they did to figure out dolphins visually perceive their world claims they have pretty poor visual acuity. That being said, they are able to recognize and point out various shapes and appear to perceive the world similarly to other mammals both under and out of water. They had particular trouble, as did chimpanzees, with discerning shapes that were similar (such as a D-shape and U-shape), and were often confused during the testing.
