Students and staff were treated to a lecture by David Smith, who gave an introduction into the knowns and unknowns of Dark Matter.
“There are things we know that we know. There are knowns unknowns, that is to say that there are things we know we don’t know. But there are also unknown unknowns.”
This intriguing quote by Donal Rumsfeld, US Secretary of Defence (2002), was used to open the Dark Matter lecture and captivated the interest of the audience from the start.
David Smith is a fellow of the Institute of Physics and the Royal Astronomical Society and he sits at the editorial board of the IOP Journal Physics Education.
Mr Smith explained how the idea of Dark Matter started as a crazy way to explain some irregularities in the motion of stars around a galaxy.
In the carefully prepared presentation, Mr. Smith, teacher of the year (2000), unveiled some of the evidence for the existence of Dark Matter and described some of the current attempts to find it.
The well-attended event, showed once more the interest at Kingsbury for Science in general and Physics in particular.
