Next meeting on September 6th – Radioactivity and Stones
This month’s presentation is about radiation and radioactivity. Radiation is all around us from natural and human-made sources creating what is known as background radiation. It is essential to understand what radiation and radioactivity are and where they can be found. The presentation will also include a look at minerals that contain radioactive elements, how they can affect other minerals, and how radioactivity drives geological processes like continental drift, vulcanism, earthquakes and mountain building.
David Bellamy finished a 34-year teaching career in June of 2018, most of which was spent at North Toronto Collegiate Institute where he taught Sciences at the grade 9 and 10 levels, and Biology as well as Earth & Space Science at the grade 11 and 12 levels, respectively. He has an eclectic thirst for knowledge, especially in the sciences. These interests include astronomy, genetics, geology, mineralogy, and zoology. He is also something of a packrat as evidenced by a sizeable collection of just about anything imaginable that is related to minerals. He has also been an avid collector of frog figurines for the last several years such that frogs have become his trademark among his friends and peers. –
