Conservation of Energy
Do not be confused by these signs. They are not based on principles of Physics.
When I pass through a revolving door I have to move four panes of glass through one hundred and eighty degrees (of rotation). That is seven hundred and twenty degrees of movement.
When I pass through a hinged door I have to move ONE pane of glass through FORTY-FIVE degrees (of rotation). That is forty-five degrees of movement.
I burn only one-sixteenth as much energy when I use the hinged door.
Whenever possible, I use the hinged door, and avoid the revolving door like the plague.
Work started on renovating this quadrangle of space back in July 2016 . Today it is still a gravel pit, and access to this space as an off-street path between Yonge, Bay, College and Gerrard streets has been denied us.
Someone has knocked down the fences.
I find it hard to understand why it takes over eight months to grade an empty space, truck in some top-soil, lay some sod, plant some trees, and then bugger off and let us use the park.
Toronto is a city that never quite manages to get a job done properly.
