Plum Pudding Model

Ah, the pretty looking plum-pudding model. The pretty looking wrong plum pudding model, that should be. Indeed, originally thought to be the pinnacle of scientific discovery, it all fell apart horribly for physics one day in 1909. Join me on this tale of woe, as we discover why physicists were wrong for years about how atomic structure looks.

So, after the informative guide on nuclear fission, there was only one natural follow-up, right? Don’t worry: this one will be somewhat shorter.

What do you have to lose?

Electricity

Electrical circuits are another section of many physics exams, and so we’re going to do a little bit of revision about them, this should be a fairly quick and easy read, but let us know all the same if you have any problems with it…

Everybody’s been doing basic electric circuits since primary school, making a light bulb light up, being annoying by constantly powering a buzzer, but some of the more complicated components don’t get introduced until later, and guess what: you need to know what they look like on a diagram!
