User talk:Hard wrk/sandbox

Just FYI i am making comments and suggestions based on other observatories pages. I also understand that there is only so much we have to write.

In the general info area up top I would make a quick mention on the date of closure and why.

In the description elaborate more on what you mean by "building on Ptolemy".

This sentence sounds weird maybe reword it differently- "Khayyam and others changed the sultan's mind"

" for the new observatory in making a zij", --- change to--- "was to construct a zij"

Add "The" in front of "Calendar would become"

References

Muslim Heritage, Encyclopedia Britannica, and sciencemag.org are not good sources to use and will not hold up. I would look at their sources and cite a peer reviewed article or book.
