Hi, I was checking my private messages under "Conversations" but was only able to see one conversation. I'm sure that I had more messages there. Are the private messages/conversations get deleted after some time? Thanks!

Yes, they mostly answer in terms of complete shells. Anyway, I will keep looking.

Hi, I have a basic knowledge of chemistry from high school days. I remember once being told that a neutral hydrogen has one electron in its shell but it wants to complete its outer shell by having two electrons, and this makes hydrogen atom to create bonds with other atoms. Likewise, a...

Thank you. It is just assumed that nature acts in some mysterious way. Though, I think that Newton himself knew that this is not really true.

Thank you for the help! About the charge example. I have always thought of a positive charge as the source and a negative charge as the sink. If a negative charge is lying along the positive x-axis and the positive charge is situated at the origin, I think that some of the the field lines...

Hi, I have a basic understanding of quantum physics. I was reading a Wikipedia article on hidden variables, https://en.wikipedia.org/wiki/Hidden-variable_theory . The article says the following. I was confused about the words "local" and "nonlocal" in the quote above so I checked out another...

Thank you very much! All those links and data are really helpful.

Thanks a lot! I find your post very helpful.

That's exactly what I had in mind. Mostly when someone has surgery or get sick, that person is mostly given meat broth so I was under the impression that it should be really nutritious.

Thank you! I agree that that would be the right way to do a scientific inquiry. When I asked the question, I was just thinking about it and needed some opinions. On the other hand, I don't think I would have been able to frame my query so nicely the way you did. Thanks!

Thank you! I think that I didn't state it clearly. I wanted to say that if you stew/boil meat and then drink that liquid (without any meat), is that liquid going to contain as many nutrients as there are in 'solid' meat? Personally, I don't think so.

Hi, Could you please help me with the queries below? Q1: It's said that meat broth is really nutritious. Does the boiling process extract the nutrients from the meat? If it does, I'd say that the boiling process cannot still extract all the nutrients from the meat. Q2: Assuming the answer to...

Thank you! I understand it now. CO2 monitor isn't really needed.

Agreed! But I think to monitor carbon dioxide levels and proper ventilation CO2 monitors could be installed in some places such as basements. Thank you, everyone, for the help!

Humans generate carbon dioxide. In some Asian countries far more people die as result of CO poisoning in winter months. When I was writing the post, I was thinking of a scenario where five or more people are sleeping in a small non-ventilated room with a furnace running on. It will increase the...
