Watermelon Drop
Run Time: 00:00:17.65 | View: Windows Media High BandWindows Media Low Band It's fun to drop a watermelon off the roof and watch it splat. But you can figure out mathematically how fast the watermelon is going at the moment of impact and the amount of energy that it lands with, which affects how far it splats.
Lake Skinner Dam Pressure
Run Time: 00:01:28.51 | View: Windows Media High BandWindows Media Low BandLake Skinner has a man made dam at one end. How do we know how strong the dam must be? The pressure of the water on the dam changes as the water gets deeper so it is difficult to measure the total force, but there are good ways to estimate this force and the methods of calculus lead us to a precise answer.
Lake Skinner Water Volume
Run Time: 00:01:08.86 | View: Windows Media High BandWindows Media Low Band Lake Skinner is a popular boating and fishing spot as well as the source of drinking water for a large number of Californians. The surface area and volume of the lake are published, but how were these values determined? We look at mathematical techniques used to estimate both areas and volumes.
Lake Skinner Fish Count
Run Time: 00:00:58.65 | View: Windows Media High BandWindows Media Low Band Many people enjoy fishing for trout on Lake Skinner. How could we estimate the number of trout in the lake? It certainly is not practical to try and catch all the fish! The capture/recapture method cleverly uses a simple proportion to provide a reasonably accurate estimate.
Crab Count
Run Time: 00:02:03.34 | View: Windows Media High BandWindows Media Low Band We use fictitious "land crabs" in Palomar's Arboretum to illustrate the idea of estimating an animal population using the capture/recapture method. This method allows us to estimate the population by catching just a small portion of it.
Palomar Mountain Tree Score
Run Time: 00:02:12.29 | View: Windows Media High BandWindows Media Low Band A mathematical formula is used to give large trees a score which is recorded in a national registry. One requirement for the formula is the tree's height. This is difficult to measure, but we show the "stick method" for a quick estimate and explain mathematically why this works.
Aeronautical Sciences
Run Time: 00:02:45.34 | View: Windows Media High BandWindows Media Low Band Palomar College instructor Jerry Hauser discusses how mathematics is used in learning to become a pilot. Examples include estimating the minimum runway length required, determining the correct weight and balance for a plane's cargo to ensure stable flight, factoring wind into navigation, and determining the time required for a flight.
Fox 6 News
Run Time: 00:01:59.65 | View: Windows Media High BandWindows Media Low Band The Chief Engineer for Fox 6 News shows us the satellite transmitter on a news van and discusses the signal strength needed to transfer the information to a satellite 22,000 miles above. It turns out that water droplets in the air naturally resonate and degrade the signal along the journey. Also we can asnwer the question: Why is 22,000 miles the distance used for orbiting satellites?
Stone Brewery
Run Time: 00:06:47.50 | View: Windows Media High BandWindows Media Low Band The head brewer of Stone Brewing Company in Escondido gives us a tour of their facility and explains the many ways mathematics is used in the brewing of beer. Examples range from simple ratios to a fairly involved equation to determine the bitterness of the beer.
Mt. Palomar Winery
Run Time: 00:03:41.08 | View: Windows Media High BandWindows Media Low Band The winemaker at Mount Palomar Winery in Temecula discusses many ways in which he uses mathematics daily in the making of wine. Examples include mixture problems and unit conversions. He also shows how to use a "Pearson Square" as a shortcut to solving some mixture problems.
Campus Tree
Run Time: 00:01:44.04 | View: Windows Media High BandWindows Media Low Band You can determine the height of a tree by measuring the length of its shadow and using similar triangles.
Palomar Observatory Inside
Run Time: 00:03:46.06 | View: Windows Media High BandWindows Media Low Band We toured Palomar Observatory to see how mathematics is used in the operation of the telescope. For example, the telescope uses a 200-inch parabolic mirror with a camera at its focus point, and a spherical coordinate system is used for its navigation. The astronomers also shoot a powerful laser into the sky to aid calibration.
Palomar Observatory Outside
Run Time: 00:03:53.45 | View: Windows Media High BandWindows Media Low Band Palomar observatory has 6 telescopes in 6 domes. The mirrors in the telescopes are all parabolic in shape. The size of each one determines how much light is collected but how much of the sky that is seen depends on the shape of the parabola. In fact, the smallest mirror actually captures much more of the sky than the largest. We also look at why a logarithmic scale is used to measure the brightness of stars.
Satellite Dish
Run Time: 00:01:36.40 | View: Windows Media High BandWindows Media Low Band The shape of a satellite dish is based on a parabola. Signal rays are transmitted from the focus of the parabola and proceed to bounce off the dish and head into space in parallel directions. A receiver dish bounces signal rays from space and concentrates them on the focus point.
