This video begins with the historical invention of logarithms that forever changed the world of computation‚ until the advent of calculators more than 300 years later. Written and hosted by internationally acclaimed math educator Dr.

In this Investigation we look at properties of logarithms. This video is Segment 1 of a 4 segment series related to Algebra Nspirations: Logarithms and Logarithmic Functions.

In this episode of Algebra Applications, students explore earthquakes using exponential models. In particular, students analyze the earthquake that struck the Sichuan Province in China in 2008, months before the Beijing Olympics.

In this Math Lab we look at patterns among different logarithm calculations. This video is Segment 2 of a 4 segment series related to Algebra Nspirations: Logarithms and Logarithmic Functions.

In this episode of Algebra Applications, students explore earthquakes using exponential models. In particular, students analyze the earthquake that struck the Sichuan Province in China in 2008, months before the Beijing Olympics.

In this Investigation we look at logarithmic functions and graphs. This video is Segment 3 of a 4 segment series related to Algebra Nspirations: Logarithms and Logarithmic Functions.

In this episode of Algebra Applications, students explore various scenarios that can be explained through the use of logarithmic functions. Such disparate phenomena as hearing loss and tsunamis can be explained through logarithmic models.

The mathematical definition of a logarithm is the inverse of an exponential function, but why do we need to use logarithms? This segment explains the nature of some data sets, where incremental changes in the domain result in explosive changes in the range.

We live in a noisy world. In fact, prolonged exposure to noise can cause hearing loss. Students analyze the noise level at a rock concert and determine the ideal distance where the noise level is out of the harmful range.

In 1998 a devastating tsunami was triggered by a 7.0 magnitude earthquake off the coast of New Guinea. The amount of energy from this earthquake was equivalent to a thermonuclear explosion. Students analyze the energy outputs for different magnitude earthquakes.

Almost everyone has an intuitive understanding that exponential growth means rapid growth. Written and hosted by internationally acclaimed math educator Dr.

March 2011. A comparison of the Japanese earthquake near Fukushima to the one in the Sichuan Province of China in 2008. We also look at the resulting tsunami that hit the Japanese coast.

March 2011. In this issue we look at the nuclear power plant in Fukushima, Japan, and the amount of heat generated from the radiation leak.

March 2011. In this issue we look at the continuing housing crisis that began in 2008. We use a spreadsheet to calculate mortgage payments.

11/6/11. In this issue we look at the listeria bacteria to see what makes this particular type of bacteria so dangerous.

April 2012. In this issue of Math in the News we look at the recent earthquake near Indonesia and compare it to the devastating earthquake of 2004.

August 2013. In this issue we analyze why the movie the Lone Ranger is considered a box office flop, even though it has earned nearly $100 million. We analyze box office data.
