I found a press release from the Institute of Physics saying that Physics provides a staggering £8 billion for the Scottish economy.
S3 Colour TV
We’ve been talking about colour tv in class and I found a few items you might want to look at. First of all, the website I used in class is available here and there is further information on combining colours here.
There is also a helpful animation of the shadow mask that stops the three electron beams from reaching the wrong phosphor dots.
S3 – How do you get a picture on a TV screen?
We’ve been looking at the demonstration picture tubes in class. Now we need to find out how to get from a single bright spot on the screen to having a picture covering the whole screen. Here is a link to the website I will be using in class to help explain how a picture is produced.
Cancer treatment by Chemotherapy
We don’t need to cover chemotherapy as part of the Standard Grade Phyics course but I thought you might be interested in how it works, now that we have looked at the use of Radiotherapy. The attached pdf file contains some notes on chemotherapy taken from the CancerHelp UK website.
S4 – laser eye correction
We’ve been looking at the various uses for lasers in surgey, including the correction of eyesight. I found this site that shows how one company does this in their clinic. The animation does a pretty good job of explaining the procedure.
