How does it work

Post by Ocker »

In the Physics store I have a board thingy with scales attached either end but no paperwork :redcard:
It is labelled "Long & Short Distance measuring Kit" made by H.B.Selby & Co centurys ago :whistle:
It has a pin-hole in one end with slides and mirrors wrapped up in greaseproof paper.
I suspect it operates something like a crude sextant, but no idea,
Has anyone else got one with instructions, I would love a copy :crazy:

I have just emailed our physics teacher. She is away at the moment so I don't know when I might have an answer (if she knows).

I hope your Physics teacher is a mature woman, I suspect Noah used these to build the ark
But It's for that reason I would perservere to get them operational

i wonder if it is one of those ASEP kits that used to be around - we had them here... I will look for the forces booklet and see if it has anything in that for you

It's distance measurement by optics, Sunray
Surveyors do something similar called Stadia
