Website showing heavens appearance at a given date
Hello! Is there a website that tells me where the sun and the planets were at a given moment in the past? I only know http://www.heavens-above.com, but there you cannot go very far in the past.

Thanks!

 * In Wolfram Alpha, you can type "Sky map for [place] [time] [date]" and get a sky chart for then. For instance, "sky map for London 1 AM 4 October 1800" gives you this. Smurrayinchester 09:47, 4 October 2017 (UTC)


 * Stellarium is usually favoured for this. It's a downloadable program, but it's free and it's cross-platform. There are several others, and a list at that article. Andy Dingley (talk) 10:00, 4 October 2017 (UTC)


 * It's all carefully worked out . 82.12.63.55 (talk) 11:16, 4 October 2017 (UTC)

Muscle and liver glycogen, which refills first?
When a person has fully depleted both their muscle and liver glycogen stores and then ingests carbohydrates, which refills first; muscle glycogen or liver glycogen? My understanding is that all carbohydrates will pass through the liver first because the blood vessels from the intestines go directly to the liver. However I have also read that the liver will not actually replenish its glycogen stores if blood sugar is low. Also, StuRat, as much as I love you (seriously, I do like reading your comments) I am looking for referenced answers to this question not just idle speculation :) Thanks for your time. 109.62.183.116 (talk) 15:46, 4 October 2017 (UTC)


 * That's fine, but why did you repost ? Is this a different Q from the one above ?  Even if it is, I'd put it right after that one. StuRat (talk) 16:01, 4 October 2017 (UTC)
 * It's a different question. The other one was about both liver and muscle glycogen stores together acting as a cabohydrate sink during excessive ingestion. This one is specifically asking which of the two refills first. 109.62.183.116 (talk) 16:21, 4 October 2017 (UTC)


 * To simplify, the liver stores glycogen, the muscles use it. When I prepped for bariatric surgery last January I had to go on a strict three-week diet for the purpose of shrinking my liver's size by 75%.  The doctor said the liver would shrink, making access to my stomach easier, but the muscles would have enough glucose as long as my blood sugar remained over 80.


 * I had to test three times a day, because your heart and lungs (and brain) have to have glucose at a sufficient level, while your liver will simply cut back on non-essential functions. No, that's not an RS, but I lived through it. I threw out the pre-op documentation, but it's easy enough to get if you google pre-op bariatric diet. 22:24, 4 October 2017 (UTC)


 * Shoot, if a person can diet well enough to keep blood sugar under 80 for three weeks and shrink their liver, why do they need bariatric surgery? Wnt (talk) 06:16, 6 October 2017 (UTC)


 * How old are you, exactly, Wnt?


 * Because it's an otherwise unhealthy starvation liquid diet, requires the use of very expensive, unsatisfying, and diarrhea and nausea inducing protein drinks, risks ketoacidosis, a potentially fatal condition, does not address the issue on the long term, and is not comfortable or cost effective?


 * Having had the laparoscopic over-night stay gastric sleeve surgery (which cost ~$10,000), I am off diabetes meds that had cost ~$12,000 year, am not on a starvation diet, and have lost over 50% of my pre-treatment body weight? And actuarial tables show I have added about 30 years to my expected life span. I am in better shape now than I was 25 years ago, and am unlikely to die or suffer amputations due to diabetic complications like about 1/2 of the people on my father's side of the family.


 * I'd give you the research, but I see no reason to humour medical conspiracy theorists. I feel, look, and test great. μηδείς (talk) 19:24, 6 October 2017 (UTC)
