If we actually roll a die 60 times we wouldn't expect each of the faces . ... times each face actually comes up is the observed frequency for that face. ...

You can do simple arithmetics % calc 2*2-8+16.789/3 + 3**2 10.5963 or more complex expressions % calc (3**2/4)**(1/3) 1.31037 and use functions (*See notes on functions): % calc sin(atan(0.95))*sqrt(4.32) 1.43154 or factorials (*See notes on factorials): % calc 5! ...

Next Previous Contents . This means that an interrupt happened that no driver expected. ... In many cases you can safely ignore this error message, especially if it only happens once or twice at boot-time. For boot-time messages, look at the messages which are nearby for a clue as to what is going on. For example, if probing is going on, perhaps a probe for a physical device caused that device to issue an interrupt that the driver didn't expect. ...

To print commands and their arguments as they are executed: cat example #!/bin/sh TEST1=result1 TEST2=result2 if [ $TEST1 = "result2" ] then echo $TEST1 fi if [ $TEST1 = "result1" ] then echo $TEST1 fi if [ $test3 = "whosit" ] then echo fail here cos it's wrong fi . This is a script called example which has an error in it; the variable $test3 is not set so the 3rd and last test [ command will fail. Running the script produces: example result1 [: argument expected . ...

... As of this time, only HTML output is supported by this template. ... The reason you need to know this is that the Examples Section only supports HTML output because the examples without images would be pretty useless. ... You'll note that all the code in the template after this line is tagged to be used only by HTML. ... Anyway, this is just to show how you could do an example. Here is an example of how the sparkle plug-in can be used to add both lens flare and a feathered edge to an image. ...

However, the first experiments with Co-60 irradiation showed loss of charge transfer performance at doses of 10krads [Lumb and Holland 1988b]. ... These studies showed that the charge transfer degradation was a more severe problem than conventional integrated circuit damage mechanisms. ... Another manifestation of radiation damage is that of dark current spike generation. ...

... These are ``quirks'' rather than ``bugs''. Below is a list of quirks. When loading a file and ``Reset Intensity Upon File Load'' is disabled, the intensity range of the previous image will be used. ... When moving between two images (such as when blinking, or when loading a new image), the display system attempts to retain the old image parameters (i.e. zoom box). What is retained are the corners of the zoom box measured in image pixel co-ordinates, not world co-ordinates. ...

The pipeline by default interpolates across the bad columns in the REDL CCD when it creates the master bias, but does not so when it processes the science data. This inconsistency can create boxy emission-like features as seen in the figure below. ...

A knowledge of mathematical methods is important for an increasing number of university and college courses, particularly in physics, engineering and chemistry, but also in more general science. ... We have therefore decided to write a textbook that assumes knowledge only of material that can be expected to be familiar to all the current generation of students starting physical science courses at university. ... The general aim of the book is to present a topic in three stages. ...

This perspective view of Marcia Crater on the giant asteroid Vesta shows the most spectacularly preserved example of "pitted terrain," an unexpected discovery in data returned by NASA's Dawn mission. ... Scientists think low-speed collisions with carbon-rich meteorites left hydrated minerals on Vesta's surface. Heat generated during later, high-speed collisions with asteroid belt rocks released water that was previously bound within the hydrated minerals. ...
