The Training Partnership - Red Card or No Red Card? Lecture

Dr Stephen Dance has been asked to give a seminar to The Training Partnership, an educational forum for A level students on mathematical subjects not covered in the curriculum. Many famous mathematicians have given this lecture, no it's the turn of acoustics! I selected Red Card or No Red Card? How acoustics can help. It will discuss if  Van Persie of Arsenal should of been sent off against Barcelona in 2011.
