About me

My name is Evan Tillotson and I'm currently studying Physics at the University of Manchester. This course is the most qualified in the country with the highest prerequisites needed. Having spent 6 years excelling in over 60 exams (so far), I feel confident saying I understand the exam system.

However, whilst acing exams is important, I love to explain the topics and concepts which confuse and befuddle. Anyone can understand quantum mechanics; it just needs to be explained in a comprehensible way. I find myself a clear, charismatic person who hopes to hear from you soon!

Best regards,

Evan

Half-life is a term commonly used in radioactivity. It defines the time taken for a radioactive source to halve its activity. A radioactive source will emit radiation (energy) through the emission of particles or photons. How many of these particles are being released every second (or any arbitrary unit of time) determines a substance's activity. This can be seen mathematically through analysing the radioactive decay equations listed in the AQA formula list here: http://filestore.aqa.org.uk/subjects/AQA-PHYA4-5-INS-JUN12.PDF. Furthermore, the maths used to derive the equation for half-life, can be explained through these equations; I would be happy to show you if you wish. In conclusion, half life is how long it takes for a radioactive substance to become half as radioactive as it initially was.
