Bare Dog Paws

If a human walks barefoot in the snow for very long, their feet would freeze.  Dogs can walk bare-paw in the snow and their paws won't freeze, because the way the blood vessels under the skin on the paw is arranged keeps the paw at the body's temperature.  For more information click here.

History of Ground Hog Day

Ground Hog Day is celebrated only in the United States and Canada, but it evolved from Candlemas celebrations that originated in Europe.  In pre-Christian times, the Romans celebrated the Feast of Lights on February 1, which became Candlemas to the Christians on February 2, and eventually led to the founding of Ground Hog Day in Canada and the U.S.  The underlying reasons for all these celebrations had to do with forecasting the last weeks of winter weather and the viability of the coming spring and summer crops.  There were also religious reasons for celebrating Candlemas, which are quite interesting.  For more information click here.

On this day in 1924, the first Winter Olympics began in Chamonix, France, which is in the French Alps.  The closing date was February 5.  The events were biathlon, bobsleigh, cross-country skiing, curling, figure skating, ice hockey, nordic combined, ski jumping, and speed skating.  For more information, videos, and photos from the 1924 games, click here.

My favorite winter sport to participate in is cross country skiing.  What is yours?  (You can leave comments below.)

Today is the first full day of winter in the northern hemisphere.  I thought that the temperature had to reach 32 degrees Fahrenheit before snow falls, but that's not true:  snow can fall when the temperature is in the 40's!  For more winter fun facts click here.

Tonight in the northern hemisphere you may be able to see the three-star constellation Fornax--unfortunately it will be an overcast, rainy night where I live, so I won't be able to see it.

The fornax is a chemical furnace, or combustion furnace, created by French chemist Antoine Laurent Lavoisier (1743-1794).  He named the furnace after Fornax, the Ancient Roman goddess of bread and baking.  French astronomer Nicolas Louis de Lacaille (1713-1762) created the three-star constellation in 1752, and named it Fornax in honor of his friend, Lavoisier.

Did you see Fornax tonight?  Have you seen it before?  What was it like seeing it tonight?

The traditional Hawaiian thanksgiving celebration is called Makahiki.  Makahiki lasts from November through February, and during this time all are forbidden to engage in work and war.  It is a time of celebrating harvests with religious ceremonies, luaus, and competitive games.
