October 7 – Happy Birthday, Niels Bohr

Posted on October 7, 2013

What can I say about a man who—while fleeing from the Nazis himself—refused his flight to safety until he made sure that other Danish Jews would have a place to go, as well?

Well, for one thing, I can say that he was a hero!

Niels Bohr was a famous scientist who contributed a lot to our knowledge about atoms and about quantum physics. Born on this date in 1885 in Copenhagen, Denmark, hen Bohr was just 20 years old, he won a gold medal competition in physics. In order to enter this competition, he had to use his dad's physiology lab because Bohr's university had no physics laboratory! Also, Bohr had to learn how to blow glass so he could create the kind of test tubes that he needed. When it came to actual assigned experiment, Bohr went above and beyond what the contest required—which is no doubt why he won! Much later in his career, Bohr won the highest prize in science: the Nobel prize.

As fascinating and important as Bohr's scientific career is, I find it interesting that he was so helpful in rescuing people during World War II. He gave Jewish scientists who were worried about Hitler temporary jobs at his institute, thus providing them financial support; he also arranged for many to receive fellowships from the Rockefeller Foundation, and he helped the scientists find permanent jobs elsewhere in the world, far from Europe.

After Hitler invaded Denmark, when it looked like Jewish people were about to be arrested and deported, Bohr was taken out of Denmark on a boat and carried off to safety in Sweden. As soon as he stepped foot in Sweden, Swedish government officials informed him of their orders to get him safely to the United States so he could work on an atomic bomb project. However, Bohr was worried about all the Jews in Denmark who were not important physicists. He refused to go anywhere until the Swedish king announced on radio and in newspaper that Sweden would take in all the Danish Jews—that they would have a new home in Sweden. Eventually Bohr made this plea in person to Sweden's King Gustaf—and Sweden did indeed take in around 7,800 Jewish Danes.

(Some historians believe that, even without Bohr's efforts, Sweden would have taken in the refugees. But other historians say that Bohr's personal plea made a huge difference in how these events played out.)

Last (and certainly least), Bohr was even able to save two scientists' Nobel medals from the Nazis (who would have undoubtedly melted them down)! Bohr directed that the medals be dissolved in acid! I know you are wondering why dissolving a gold medal in acid is better than melting a gold medal down into a lumpbut the Nazis would have that gold lump to pay for weapons and ammunition. Whereas, after the war, the scientists were able to precipitate the gold from the acid and have the Nobel committee re-strike their medals. Good as new!

Back to Atoms...
Check out this YouTube video of the structure of an atom. (Note: This super-simple look doesn't get into the quantum realities that Bohr worked out.) 

This video is a more advanced look at Bohr's model of the atom. 

Here is a Nova special on quantum physics, the field that Bohr helped start.

April 16, 2013 - One Day Without Shoes

Today people are trying to bring global awareness of children's health and education in an unusual way – by going without shoes. Check out this video, and this official website, and last year's post




AND
The Queen's Birthday in Denmark

Margrethe, Margrethe, come on out, or we will never go home!” call loyal citizens of Denmark on their queen's birthday.

They do this standing below the public balcony of the Royal Amalienborg Palace. And sure enough, Queen Margrethe and a few members of her family step out onto the balcony and greet the cheering crowd.

The funny thing (to me) is that the tradition dictates that this happen several times. After smiling and waving to the crowd, the queen will go back inside. The crowd will make their traditional call again (rather like calling to Rapunzel or Juliet, isn't it?), and she will step out again—three or four times altogether.

Do things Danish, today!

  • Licorice fudge
    Licorice is a popular flavor for desserts—licorice ice cream, licorice chocolate, licorice fudge, licorice mints, and of course licorice candy. The Danes apparently especially like salty black licorice. (I'm thinking, “Salty??”) You probably cannot find all of these licorice treats in your local grocery store, but perhaps you can add some pieces of licorice to vanilla ice cream.



  • Play Vikings. Play with Legos. Perhaps you can play Vikings WITH Legos!
  • Here are instructions for creating a Viking ship out of a milk carton.


  • Do some Danish-inspired folk art. Use paint or paper-cutting to create symmetrical folk designs. Check out this and that and this other websites for some ideas. (Scroll down at the last link.)
