12 Science Valentines

There are Valentine cards, ecards, and gifts for every taste imaginable! If you don't find a card or image that perfectly expresses your sentiments, you can easily make your own. And if you lack the imagination, skills, or time to create one, someone else probably has just what you're looking for. The scientific community is no exception -and they take advantage of every opportunity to make a pun when they can. Here are some valentines from different scientific disciplines. Keep in mind that for almost every image here, you can find follow the links and find more clever science valentines.

1. General Science

Aaron Lurch put his imagination to work to create a valentine for his wife Mindy. The result was a display worthy of any 7th grade science fair project, complete with a graph of his results. At his site, you can click to enlarge this picture enough to read it -it's quite clever!

2. Evolution

David Friedman at Ironic Sans made several scientist valentines. This one features, of course, Charles Darwin and his theory of natural selection. Others depict Sir Isaac Newton, Carl Sagan, Marie Curie, and Albert Einstein.

3. Behavioral Psychology

Alex at Neatorama set out to represent the scientists who had not been enshrined in valentines in Friedman's collection. Besides Pavlov, you'll find Stephen Hawking, Amedeo Modigliani, Archimedes, and Nikola Tesla expressing their romantic sides.

4. Chemistry

Not to be outdone, Jack of Science made up a collection of valentines that used scientific puns, like this one that illustrates capsaicin. At least I'm pretty sure that's what this is.

5. Computer Science

Garrison Dean created science fiction valentines for io9 last year, including this creepy sentiment from HAL9000.

6. Genetics

Maybe you can help me out on this one. There's no explanation of what this image really represents (besides love), and the original has been deleted. I think it may have something to do with DNA sequencing.

Update: Natalie helped me out (thanks!):

It's the result of electrophoresis, where molecular biologists inject DNA samples into a gel and then use electric current to run them across the gel, since DNA is negatively charged. The banding patterns created, like in the image above, are then compared for similarities. For any forensics junkies, this is how they actually do DNA fingerprinting.

7. Medicine

Sheila at Cheeky Magpie made a variety of valentines in the shape of an anatomically correct heart. She also posted the basic pattern that you can print out and use yourself. Hey, it's a heart! It could be worse!

8. Math

Gotta love fractals, which are cool in any form. Randall Munroe of xkcd stuck infinite hearts into this Sierpinski valentine. In 2010, he posted a bittersweet valentine invoking the scientific method.

9. Astronomy

Dr. Phil Plait, who regularly addresses the issue of pareidolia in outer space and elsewhere, created a valentine with the "face on Mars" that we've all seen.

10. Physics

Stephanie Burrows makes real cardstock valentines for sale at Etsy. A set of 16 feature 8 different scientists saying something you'd expect them to for the holiday.

11. Marine Biology

Science, love, and the horrors of the deep made cute, as happens a lot on the internet. That's P.Z. Myers' cephalopod valentine, because even cuttlefish like to cuddle!

12. Microbiology

Microbes proliferate in Petri dishes and agar plates, sometimes in colonies that form interesting patterns. However, this one was modified especially for Valentines Day to express the proper sentiment.

Scientists and science geeks have options besides valentine cards and images. You can pass along some science poetry from this roundup at The Scientific Activist. Or share some valentine experiments, courtesy of Steve Spangler. Spangler has more suggestions this year for injecting a little science into your Valentines Day activities, no matter whether you are a scientist or not.

8 Legendary Monsters of Christmas

The customs of the holiday season, which include St. Nicholas Day, New Years Day, and Epiphany, as well as Christmas, often incorporate earlier pagan traditions that have been appropriated and adapted for contemporary use. Customs that encourage little children to be good so as to deserve their Christmas gifts often come with a dark side: the punishment you'll receive from a monster or evil being of some sort if you aren't good! These nefarious characters vary from place to place, and they go by many different names and images.

1. KRAMPUS

As a tool to encourage good behavior in children, Santa serves as the carrot, and Krampus is the stick. Krampus is the evil demon anti-Santa, or maybe his evil twin. Krampus Night is celebrated on December 5, the eve of St. Nicholas Day in Austria and other parts of Europe. Public celebrations that night have many Krampuses walking the streets, looking for people to beat. Alcohol is also involved. Injuries in recent years have led to some reforms, such as requiring all Krampuses to wear numbers so they may identified in case of overly violent behavior.

Krampus may look like a devil, or like a wild alpine beast, depending on what materials are available to make a Krampus costume. In modern times, people can spend as much as they like to become the best Krampus around—and the tradition is spreading beyond Europe. Many cities in America have their own Krampus Nights now.

2. JÓLAKÖTTURINN

Jólakötturinn is the Icelandic Yule Cat or Christmas Cat. He is not a nice cat. In fact, he might eat you. This character is tied to an Icelandic tradition in which those who finished all their work on time received new clothes for Christmas, while those who were lazy did not (although this is mainly a threat). To encourage children to work hard, parents told the tale of the Yule Cat, saying that Jólakötturinn could tell who the lazy children were because they did not have at least one new item of clothing for Christmas—and these children would be sacrificed to the Yule Cat. This reminder tends to spur children into doing their chores! A poem written about the cat ends with a suggestion that children help out the needy, so they, too, can have the protection of new clothing. It's no wonder that Icelanders put in more overtime at work than most Europeans.

3. FRAU PERCHTA

Tales told in Germany and Austria sometimes feature a witch named Frau Perchta who hands out both rewards and punishments during the 12 days of Christmas (December 25 through Epiphany on January 6). She is best known for her gruesome punishment of the sinful: She will rip out your internal organs and replace them with garbage. The ugly image of Perchta may show up in Christmas processions in Austria, somewhat like Krampus.

Perchta's story is thought to have descended from a legendary Alpine goddess of nature, who tends the forest most of the year and deals with humans only during Christmas. In modern celebrations, Perchta or a close relation may show up in processions during Fastnacht, the Alpine festival just before Lent. There may be some connection between Frau Perchta and the Italian witch La Befana, but La Befana isn't really a monster: she's an ugly but good witch who leaves presents.

4. BELSNICKEL

Belsnickel is a male character from southwestern German lore who traveled to the United States and survives in Pennsylvania Dutch customs. He comes to children sometime before Christmas, wearing tattered old clothing and raggedy fur. Belsnickel carries a switch to frighten children and candy to reward them for good behavior. In modern visits, the switch is only used for noise, and to warn children they still have time to be good before Christmas. Then all the children get candy, if they are polite about it. The name Belsnickel is a portmanteau of the German belzen (meaning to wallop) and nickel for St. Nicholas. See a video of a Belsnickel visit here.

Knecht Ruprecht and Ru Klaas are similar characters from German folklore who dole out beatings to bad children, leaving St. Nicholas to reward good children with gifts.

5. HANS TRAPP

Hans Trapp is another "anti-Santa" who hands out punishment to bad children in the Alsace and Lorraine regions of France. The legend says that Trapp was a real man, a rich, greedy, and evil man, who worshiped Satan and was excommunicated from the Catholic Church. He was exiled into the forest where he preyed upon children, disguised as a scarecrow with straw jutting out from his clothing. He was about to eat one boy he captured when he was struck by lightning and killed—a punishment of his own from God. Still, he visits young children before Christmas, dressed as a scarecrow, to scare them into good behavior.

6. PÈRE FOUETTARD

The French legend of Père Fouettard, whose name translates to "Father Whipper," begins with an evil butcher who craved children to eat. He (or his wife) lured three boys into his butcher shop, where he killed, chopped, and salted them. St. Nicholas came to the rescue, resurrected the boys, and took custody of the butcher. The captive butcher became Père Fouettard, St. Nicholas' servant whose job it is to dispense punishment to bad children on St. Nicholas Day.

7. THE YULE LADS

The Jólasveinar, or Yule Lads, are 13 Icelandic trolls, who each have a name and distinct personality. In ancient times, they stole things and caused trouble around Christmastime, so they were used to scare children into behaving, like the Yule Cat. However, the 20th century brought tales of the benevolent Norwegian figure Julenisse (Santa Claus), who brought gifts to good children. The traditions became mingled, until the formerly devilish Jólasveinar became kind enough to leave gifts in shoes that children leave out ... if they are good boys and girls. 

8. GRÝLA

All the Yule Lads answer to Grýla, their mother. She predates the Yule Lads in Icelandic legend as the ogress who kidnaps, cooks, and eats children who don't obey their parents. She only became associated with Christmas in the 17th century, when she was assigned to be the mother of the Yule Lads. According to legend, Grýla had three different husbands and 72 children, all who caused trouble ranging from harmless mischief to murder. As if the household wasn't crowded enough, the Yule Cat also lives with Grýla. This ogress is so much of a troublemaker that The Onion blamed her for the 2010 eruption of the Eyjafjallajökull volcano.

History
84 Years Ago Today: Goodbye Prohibition!

The repeal of prohibition was a key policy of Franklin Roosevelt's government as it allowed the government an opportunity to raise tax revenues at a time of economic hardship.

It was 84 years ago today that the Twenty-First Amendment to the Constitution was ratified, repealing the earlier Amendment that declared the manufacture, sale, and transport of alcohol illegal in the United States. Prohibition was over! Booze that had been illegal for 13 years was suddenly legal again, and our long national nightmare was finally over.

Prohibition of alcohol was not a popular doctrine. It turned formerly law-abiding citizens into criminals. It overwhelmed police with enforcement duties and gave rise to organized crime. In cities like Milwaukee and St. Louis, the dismantling of breweries left thousands of people unemployed.

Homemade alcohol was often dangerous and some people died from drinking it. Some turned to Sterno or industrial alcohol, which was dangerous and sometimes poisoned by the government to discourage drinking. State and federal governments were spending a lot of money on enforcement, while missing out on taxes from alcohol.

The midterm elections of 1930 saw the majority in Congress switch from Republican to Democratic, signaling a shift in public opinion about Prohibition as well as concerns about the depressed economy. Franklin Roosevelt, who urged repeal, was elected president in 1932. The Twenty-first Amendment to the Constitution was proposed by Congress in February of 1933, the sole purpose of which was to repeal the Eighteenth Amendment establishing Prohibition.

With passage of the Constitutional Amendment to repeal Prohibition a foregone conclusion, a huge number of businessmen lined up at the Board of Health offices in New York in April of 1933 to apply for liquor licenses to be issued as soon as the repeal was ratified.

The Amendment was ratified by the states by the mechanism of special state ratifying conventions instead of state legislatures. Many states ratified the repeal as soon as conventions could be organized. The ratifications by the required two-thirds of the states was achieved on December 5, 1933, when conventions in Ohio, Pennsylvania, and Utah agreed to repeal Prohibition through the Amendment.

Liquor wouldn't officially be legal until December 15th, but Americans celebrated openly anyway, and in most places, law enforcement officials let them.
