January is the month in which the mathematician Sofia Kovalevskaya (January 15, 1850) was born. She was born in Moscow and was exposed to math at a young age. She claims to have studied her father's calculus notes that were papered on her bedroom wall due to a shortage of wallpaper. When she was fourteen she taught herself trigonometry in order to understand sections of a physics book she was reading. Once, the best job she was offered was teaching math in an elementary school to which she remarked "I was unfortunately weak in the multiplication table." Her scientific papers contained ground-breaking theories and were the inspiration for future discoveries.
January is also the month in which Joseph-Louis Lagrange was born (January 25, 1736). He was born in Turin, Italy but spent the last 26 years of his life in Paris. He was one of France's most famous mathematicians. He was also responsible for the adoption of the metric system. His fame helped spare his life during the French Revolution. His friend Antoine Lavoisier, the "Father of Modern Chemistry" was not so lucky. When Lavoiser was guillotined during the Reign of Terror, Lagrange famously said, "It took them only an instant to cut off this head, and one hundred years might not suffice to reproduce its like." Lagrange is buried in the Panthéon in Paris with others like Voltaire, Victor Hugo, Louis Braille, and Marie Curie. There is a Paris street named in his honor and his name is on a plaque on the Eiffel Tower.
"The dictionary is the only place where success comes before work."
-Vince Lombardi

Vince Lombardi won six divisional championships, five NFL Championships and Super Bowls I and II as head coach of the Green Bay Packers. Before he began his coaching career, Lombardi taught algebra at a New Jersey high school.

Wind Chill is a measure of the chilling effect experienced when strong winds are combined with cold temperatures. The wind chill temperature is what the temperature "feels like" to people and animals during cold weather. It does not apply to plants or vegetation because they are not warm-blooded. We all know that a windy winter day can feel much colder than a calm one, although the air temperature may be exactly the same. The term "wind chill" was first coined back in 1939 and a formula to calculate it was published in 1945. In 2001, the U.S. and Canadian Weather Services replaced that formula with the one shown below. The new formula to calculate wind chill (WC) uses many algebra concepts.

WC = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16

where T = temperature (°F) and V = wind speed (MPH). For example, if it is 30°F and the wind is 20MPH, it feels like 17°F.
