SPTR.net was for several years, a resource sharing site for physics teachers in Scotland. That role was taken up by Sally over at Guzled in 2016.
I have this week relocated the sptr.net1 website to a new home, and removed a lot of the old, dead posts, keeping just a few of particular interest or significance.
Contact us over at cullaloe.net, or use the contact form.
The sptr.net domain is either not for sale, or you can’t afford it. ↩
