October 4

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 [1]. 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)
