... The Boolean object is an object wrapper for a boolean value. ... JavaScript 1.3: added toSource method . ... If value is omitted or is 0, -0, null, false, NaN , undefined, or the empty string ( "" ), the object has an initial value of false. All other values, including any object or the string "false" , create an object with an initial value of true. ... For Boolean objects and values, the built-in toString method returns the string "true" or "false" depending on the value of the boolean object. ...

It was during "sharing" time in my first week as a teacher's aide at Sunset View Elementary School in San Diego. ... So how can we get our school teachers to know more about science? One approach is to provide science enrichment programs for current and prospective teachers, and many such programs have had success. But there's a second approach that deserves far more attention than it has received: providing opportunities for scientists to become classroom teachers. ...

It is now possible to specify multiple log files, each with a fully customizable format. ... Multiple log files are implemented as part of the mod_log_config module which as of Apache 1.2 is the default log module. Multiple log files be created with either the TransferLog or CustomLog directive. These directives can be repeated to create more than one log file (in previous releases, only one logfile could be given per server configuration). ... Syntax: CustomLog filename "format" . ...

... COMPUTER SIMULATION OF RADIOWAVE MULTIPLE SCATTERING EFFECTS IN IONOSPHERE USING MONTE-CARLO METHOD . ... Distribution of reflected radiation on the ground is computed. ... Such influence can be remarkable if the scattering is multiple, i.e. the optical thickness for the scattering process is considerably greater than a unit. ...

EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

A spherical meteorite of radius 3m enters the Earth's atmosphere at an altitude of 100km and a speed (relative to the Earth) of 30 km/s. The atmosphere slows it down, so when it hits the Earth's surface it is travelling at only 1 km/s. If half of the heat generated as it passes through the atmosphere is absorbed by the meteorite, how hot will it be when it is about to land? ... However, the number I calculated (500,000 K) is correct, as is the discussion that follows it. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...
