πŸ“· Fog over the Central Experimental Farm, Ottawa, Canada. I work on a farm in the middle of a capital city!

ℹ️πŸ§ͺ The Central Experimental Farm is located in Ottawa, Ontario and was established in 1886 as the central research station for the federal Department of Agriculture, agriculture.canada.ca.

Did same for me. Only found 3 out of 40. Even though they are all listed on an academic website.

Saw them December 84 at the Playhouse. Went with a pal who liked them. Maybe 100 people there. Touring the Heartland album.

Five years later they were selling out Murrayfield.

Making money off the backs of young people who want to better their lives through education loans is abhorrent and counter productive. I’d sign this if I lived in the UK.

Wien's displacement law - Wikipedia

For physics fans, this is described in Wien's Displacement Law, where the peak of the energy curve emitted from a body is inversely proportional to its temperature. The Sun's T=5778K gives peak emission wavelengths of 500nm (nr the peak sensitivity of the human eye)
