Fourier Welcomes New Company CEO |
 |
| |
|
|
| |
 Fourier is pleased to announce and welcome the new company CEO, Mr. Hai Ben-Israel, replacing Mr. Dov Bruker. Mr. Ben-Israel brings a wealth of scientific, engineering and business management knowledge from his experience as COO at Lumenis, a global leader in medical and aesthetic lasers and light-based technology. Prior to this Mr. Ben-Israel acted as the CEO for Tadiran Electronic Systems, designers, developers and manufacturers of EW and command and control systems. Mr. Ben-Israel served many years in the Israeli Air Force, reaching the position of Head of the Logistical Department, with the rank of Colonel. Mr. Hai Ben-Israel has an Industrial Engineering and Management degree from Ben Gurion University, Israel as well as a Masters in Business Management from Bar Ilan University, Israel.
Fourier thanks Mr. Bruker for his dedicated service and for the success he has brought to the company. He will remain an integral part of Fourier Systems, managing and developing key accounts, strategic partnerships and tenders.

Profile: Teri Rossman's Mathematics Goes Green! Project - Fourier's Computing Science Exploration Grant Winner |
|
| |
|
|
| |
 The Fourier Systems Computing Science Exploration Grant Program led to many interesting applications describing innovative class projects for science. Spring Valley CCSD 99 will be implementing a classroom set of Nova5000s, the student mobile learning devices from Fourier Systems. In addition, they will receive a US$500 voucher to equip a math and science lab with a selection of scientific probeware for conducting experiments. The district’s implementation of "Mathematics Goes Green!" will be led by Technology Director, Teri Rossman, and Mark Abbott, a sixth grade math teacher at John F. Kennedy Elementary School. With the help of the Fourier Systems grant program, the school district is working to meet the state’s one-to-one computing initiative set forth by Governor Pat Quinn.

Fourier's Top Ten Fun Math Sites |
|
| |
|
|
| |
 It's sometimes hard to make students understand how useful math can be to them and in fact how critical math skills are in the 21st Century. Teachers have found that applying specific math skills to real-life situations helps students understand math concepts better, work harder and perform better. We’ve found some of the best sites available for teachers and parents to use as a resource in making math interactive, fun and relevant for students.

Probe of the Month: Colorimeter |
|
| |
|
|
| |
 The Colorimeter sensor is designed to determine the concentration of a solution by analyzing its color intensity. The Colorimeter measures the intensity light transmitted through a sample at a selected wavelength. The Colorimeter is ideal for use in a wide range of experiments in Biology and Chemistry and is supplied with three color-filter slides and fifteen cuvettes. Typical experiments include determining the concentration of an unknown solution, measuring reaction rates, measurements of glucose synthesis during photosynthesis, the effect of light on chlorophyll levels in plant leaves, the effect of enzymes on food stuff, The Lambert-Beer Law and chemical equilibrium: Finding a Constant, Kc.

 This month's free experiment download is The Lambert-Beer Law experiment using the Colorimeter sensor and taken from the Fourier Chemistry Experiments with Nova5000 experiment book. The amount of light penetrating a solution is known as transmittance, expressed as the ratio between the intensity of the transmitted light, it, and the initial light intensity of the light beam.
Even though the relationship between transmittance and absorbance would appear to be a simple inverse relationship, the true relationship between these two variables is inverse and logarithmic. The absorption of a dissolved substance is a linear function of its concentration, the so-called Lambert-Beer Law. The length of the light path (thickness of the cell) and the Extinction coefficient (a substance specific constant) determine the slope of the linear plot. The Lambert-Beer Law however is valid only for diluted solutions. The limits for its validity differ for different materials. As a general rule, one can understand that every material showing absorption of up to 0.5 - 0.6 still obeys the Lambert-Beer Law. In this experiment, we follow the behavior of the linear absorption increase of CuSO4 with increasing concentration in order to determine its extinction coefficient at a given wavelength within its absorption area.
