Hi,
I notice you reverted my recent edits on the neutron star page saying they are incorrect. Could you please explain why you think they are wrong?

the derivative of P with respect to time. It is defined as periodic time increase per unit time: yes I agree with you, that's why I self-reverted. It was an error when I wrote the text, I was thinking of the frequency.
However, as a neutron star ages, the neutron star slows (P increases) and the rate of slowing decreases (P-double dot decreases): I not sure this is correct, but I've left it as it for the time being. The thing is if P-dot decreases at a steady rate, then the P-double dot, being the second derivative of P (with respect to time) should be constant negative value, not decreasing.
Of course if P-dot decreasing rate slows (i.e. P-dot versus time graph flattens with time), then the P-double dot would increase with time. Is this what you're implying with the edit? I'm not sure it's something we can assume. Is this in fact the case? --Jules (Mrjulesd) 03:07, 3 January 2019 (UTC)

Actually, it is in Google. I fi put the link in the source, will you keep my revision? — Preceding unsigned comment added by 67.83.21.254 (talk) 22:01, 10 April 2019 (UTC)
Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Kaifeng (disambiguation), you added a link pointing to the disambiguation page Siege of Kaifeng (check to confirm | fix with Dab solver). Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)

Hello,
Google Code-In, Google-organized contest in which the Wikimedia Foundation participates, starts in a few weeks. This contest is about taking high school students into the world of opensource. I'm sending you this message because you recently edited a documentation page at the English Wikipedia.
I would like to ask you to take part in Google Code-In as a mentor. That would mean to prepare at least one task (it can be documentation related, or something else - the other categories are Code, Design, Quality Assurance and Outreach) for the participants, and help the student to complete it. Please sign up at the contest page and send us your Google account address to google-code-in-admins@lists.wikimedia.org, so we can invite you in!
From my own experience, Google Code-In can be fun, you can make several new friends, attract new people to your wiki and make them part of your community.
If you have any questions, please let us know at google-code-in-admins@lists.wikimedia.org.
Thank you!
