Philip M Russell Ltd was formed in 2011 after I left full time teaching and went freelance. The company follows my two passions. Making Videos and teaching. So now I do both. Being a Science and Maths teacher I have tended to make science videos and currently we have over 300 of them covering much of the syllabuses of Maths, Chemistry, Physics and Biology from GCSE to A Level. Over the past 10 years or so I have collected most of the science equipment to teach and demonstrate all the science experiments carried out in schools and colleges and a lot more.
