### What is seeing? Part 1: How most people ‘see’

How do you see? It seems a fairly basic question with a fairly obvious answer, doesn’t it? But let’s think about it a little bit… I’m currently in my garden looking at a tree. There are birds flying around and I can hear them

### Personal Statement for Engineering – How to Structure Yours

When you start thinking about writing your personal statement, it can be more challenging if you’re applying for a subject which is not commonly taught in schools. Engineering is a very popular course choice with great career and development opportunities. It also has a

### Series and parallel circuits

Today I am covering series and parallel circuits. In my last two posts I wrote about charge, current and voltage, and then about resistance. I tried to give a clear picture of what each one is and what it is not. If you have

### Uncertainties in Physics

As part of the A-level practical endorsement, and on the exam papers, you will be expected to show competence in answering uncertainties questions in physics. Uncertainties questions in physics are almost always in the context of a practical, and they tend to follow a

### Electrical resistance and Ohm’s law

Electrical resistance and Ohm’s law In my last post, I wrote about a fairly extensive piece on charge, current, and voltage in electricity. I said some things have something called charge and some things do not. Like charges repel, opposite charges attract. Electrons all

### Physics Practice Questions – Why Are They So Essential?

### Implicit differentiation and its use in derivatives

Implicit differentiation is one of the types of derivatives used widely in differentiation calculus is a sort of derivative in which the derivative of the equation must be determined. Differentiation calculus is a type of calculus that is mainly used to find the rate
