Reviewer: Sayantan (talk|contribs) 13:16, 1 January 2011 (UTC)[reply]

I'll review the article as soon as possible.--Sayantan (talk|contribs) 13:16, 1 January 2011 (UTC)[reply]

It's been three weeks; are you still reviewing it? Wizardman _{Operation Big Bear} 05:32, 25 January 2011 (UTC)[reply]

Ok, I will take this over as Sayantan seems to have disappeared. Jezhotwells (talk) 23:48, 31 January 2011 (UTC)[reply]

I shall be reviewing this article against the Good Article criteria, following its nomination for Good Article status.

Disambiguations: none found

Linkrot: none found. Jezhotwells (talk) 23:54, 31 January 2011 (UTC)[reply]

Checking against GA criteria

GA review (see here for criteria)

It is reasonably well written.
a (prose): b (MoS for lead, layout, word choice, fiction, and lists):
She was aware of the importance of science and ordered to offer Leonhard Euler to "state his conditions, as soon as he moves to St. Petersburg without delay". "and ordered to offer Leonhard Euler to .... " Please rewite in plain English. This is completely non-grammatical.

Soon after his return to Russia Leonhard Euler proposed to the director of the Russian Academy of Science to invite the mathematics professor Anders Johan Lexell to study mathematics and its application to astronomy, especially the spherical geometry. "proposed to ... to invite" Rewrite in English observing English grammatical norms.

wrote a paper on integral calculus calles "calles"

OK this needs a thorough copy edit, it should never have been nominated in this appallingly badly written form. Suggest a copy-edit, a peer review before renomination. Quickfail.
It is factually accurate and verifiable.
a (references): b (citations to reliable sources): c (OR):
It is broad in its coverage.
a (major aspects): b (focused):
It follows the neutral point of view policy.
Fair representation without bias:
It is stable.
No edit wars, etc.:
It is illustrated by images, where possible and appropriate.
a (images are tagged and non-free images have fair use rationales): b (appropriate use with suitable captions):
Overall:
Pass/Fail:
This article is extremely badly written. Please get it copy edited by someone who can write good plain English before renomination. Jezhotwells (talk) 00:03, 1 February 2011 (UTC)[reply]

Is December 24, 1740 birthdate under the Julian or Gregorian calendar?

Lexell was born in 1740, but Sweden (which Finland was part of at the time) didn't adopt the Gregorian calendar until 1753. Is the listed birthdate in this article of December 24th, 1740 under the Gregorian (New Style) calendar? If so, shouldn't a Julian (Old Style) calendar date be added? — Preceding unsigned comment added by Bunkyray5 (talk • contribs) 01:31, 28 December 2020 (UTC) Forgot to sign my post Bunkyray5 (talk) 01:35, 28 December 2020 (UTC)[reply]

work in spherical geometry/trigonometry

Lexell did important work in spherical geometry which it would be great to describe here. Some references:

I’ll try to get around to creating a page about Lexell's locus or Lexell's theorem (with one title redirecting to the other) at some point. But the folks here, who seem to have done a good job with other parts of Lexell's work, might be interested to add some material to this article as well. –jacobolus (t) 05:02, 17 February 2023 (UTC)[reply]

Update: Lexell's theorem was created. This article could still describe more of Lexell's relevant work in spherical geometry/trigonometry though. –jacobolus (t) 00:55, 14 January 2024 (UTC)[reply]
