S3 - shadow mask in a colour TV January 22, 2007

An apology - I totally forgot that I had this animation on my laptop. It shows how the shadow mask prevents electrons from each gun hitting the wrong phosphor pixels on a colour tv screen.

This week, we looked at the way different colors are produced inside a colour tv. I found a page that might help you to see what’s going on. Have a look at it here.

Free physics software for THS pupils! January 16, 2007

Posted by mrmackenzie in : Standard Grade, Uncategorized , add a comment

The Physics department has purchased a 1 year site license for a really smart software package called Crocodile Physics.  The terms of the license allow any pupil in the school to download a copy for home use.  If you are interested, mac and windows versions of the software can be obtained by going to www.crocodilia.com and logging in with the user name “student.thurso” and the password your teacher will give you (I can’t publish the password here).  Select Crocodile Physics from the drop-down menu and log in.  Go to the download section to get your copy of the software.

The site also contains sample models for you to download and try out.  Ask me if you want to know more about them.

In the past week, we’ve been looking at picture tubes to see how images are formed in a TV set.  Today we started to look at how a TV produces a colour image.  If you would like to look again at the web page I used in class, you can find it here.

Physics video competition on YouTube.com January 13, 2007

Posted by mrmackenzie in : Uncategorized , add a comment

I mentioned the 2007 Phylm competition to some of you this week. An American teacher has put up a prize of $100 for the best short film on a physics topic. The Phylm Prize, pronounced “film,” is an award aimed at spurring interest in physics and the educational use of new media.

The legal stuff and entry details are available in this competition rules document and there is an explanation available online in this youtube video clip.

Why am I telling you this? Well, the school has suitable digital video equipment and editing software† available to help anyone interested in producing a high quality entry - all you need is an idea for a film. Best of all, the money and prestige are all yours.

Think about it.

†If you ask nicely, you might get to use a shiny white apple laptop with iMovie.
