... For Teachers . ... Covering the Earth's magnetism in a high school course on Earth sciences addresses two important problems of the science curriculum. On one hand , the customary sequence allocates to physics just one year (and that as an elective!), not nearly enough to sample all areas of physics. ... The story of Oersted and his unexpected discovery of a link between magnetism and electricity prepares the student for later study of electromagnetism in physics class. ...

VIEW OUT OF THE WINDOW FROM ARIZONE, USA . ... Our whole class was excited to share with you what we see when we look out our window here, in Chandler, Arizona. Our classroom has no windows, so we decided to go outside on February 2, 1998, and describe to you what we see. You look out across the desert and you see endless roads and it sees almost as if you are in a dream. It's cold; about 65 degrees F (cold for Chandler, anyway) and there has been a touch of fog this morning. ...

... Telescopes . ... 1994: . World-class sensitivity was reached at the RATAN-600 radio telescope in three centimeter wavelengths (2.7, 3.9, and 7.6cm): 3.2, 3.4 and 2.5mK/s, respectively through the introduction of cryogenic low-noise amplifiers based on the high electron mobility transistors (HEMT) in the radio astronomy observations. A new-generation 2D-spectrograph featuring a CCD, mounted inside the high-aperture Schmidt camera was developed and put into service at the BTA telescope. ...
