Two weeks ago, I sat through a lesson which revolved around a Powerpoint of the simplified Standard model. There wasn’t too much information, but to fit it in 1024×768 pixels it is near unreadable.

The presentation revolved around one slide, which details gradually appeared on, however to get the level of details needed at AS level, there was a considerable amount of text, which meant it was all small and pixelated.

I left the lesson, having managed to make a rough copy of the diagram based on what was said as each element appeared, and copied this onto Prezi.com.

Prezi is brilliant, and as of very recently they have an educational version available, which just needs a school e-mail address to register for. It creates a big animated presentation, which moves around and zooms in and out of one page, which can contain loads of text, images, youtube videos and lots more!

I have tried to copy my diagram into the Prezi editor, and it’s embedded at the top of this post. For best results, and especially if it does get through on a projector, once you’ve loaded it up with the ‘Play’ button, make sure you click the Full Screen button on the ‘more’ menu. You can either scroll in and out to zoom and make your own way around or click the forward and back arrows to move through the details in a logical order.

This is by no means a finished piece, and open to comments and suggestions as to what I should do with it next, and if there are any typos I’ve missed or anything similar!

This means my resolutions are actually going quite well. This is both a creative multimedia creation, and it’s educational! Brilliant!

My front door is fitted with a wireless door bell. It’s pretty simple, no channels or anything, and 8 tunes. The middle door is fitted with a magnetic switch, which is part of a complete wireless burglar alarm system.

When I got home this afternoon, I walked through the front door. Fine. The alarm wasn’t set. Fine.

When I opened the middle door, which has a magnetic door sensor attached, the doorbell started playing a tune, not one of the tunes that it can be set to either.

Since then, every time the door with the magnetic switch attached opens, the doorbell makes an annoying beeping noise, which also isn’t one of the options.

Batteries are out now, so everyone’s happy, but why are these interacting now, when they haven’t at all before, and why does the door bell play a tune that isn’t one of the available options?

Ideas welcome…
