If reincarnation is true, I don't want to be reincarnated back into some nasty primitive society and suffer a future miserable existance. I want nothing but a utopian world to come back to in any possible future lifetimes on this planet. I, my immortal soul, got lucky enough just to be born into America this lifetime. My soul really got spoiled this lifetime. I say make the world a bowl of cherries for every living thing. Would YOU like to live as a Bushman and drink muddy water out of a puddle? Those people must smell very badly. I love the comforts of my western civilization Our future is supposed to be bringing us clean-burning vehicles anyway. One of the reason's I want our species to die down to a lower number is that so each and every person on earth can enjoy a modern vehicle without harming the environment provided clean energy one day powers them. What was the American Dream in the 1950's, I want to become the World Dream of the future. I also don't want to live in a society where folks are jammed onto subway trains like cattle. The human race would also do well to do away with those nasty nuclear weapons forever. Leonard Nimoy had a song called Highly Illogical in the 1960's. He sang Man made a mess out of planet Earth and might someday do the same to other parts of the universe with emerging space travel technology. I hope we don't mess some future planet up too like we did poor green Mother Earth.

Ok this is simply useful to understand the FLRW acceleration equation above in terms of the first law of thermodynamics. expansion is a homogeneous and isotropic that is maximally symmetric. This expansion is also adiabatic in thermodynamics if you have a container (system)there is no net outflow of energy with the surroundings. This also describes a conserved system. \(T^{\mu\nu}_\mu\). The first law of thermodynamics for an adiabatic expansion is \[de=pDv=0\] with \(E=\rho V\) and \(V=\frac{4}{3}\pi a^3\) this becomes \[d(\rho a^3)+pda^3=0\] with respect to cosmic time \[\dot{\rho}+3(\rho+p)\frac{\dot{a}}{a}=0\] differentiating the first Friedmann equation in the form \[\dot{a}^2=\frac{8\pi G\rho a^2}{3}-kc^2\] gives \[2\dot{a}\ddot{a}=\frac{8\pi G}{3}(\dot{a}a^2+2a\dot{a})\] substituting \(\dot{\rho}\) from the first law \[2\dot{a}\ddot{a}=\frac{8 \pi G}{3}a\dot{a}(-\rho-3p)\] gives the acceleration equation \[\frac{\ddot{a}}{a}=-\frac{4\pi G}{3}(\rho+3p)\] you can find other forms of the above in different literature its a fairly standard heuristic Newtonian treatment. Its useful to recognize how thermodynamics is used to describe our universe expansion as well as understanding how the equations of state apply which is already above. Hope this helps

Hehe hehe hehe, dad jokes!

Hi. It is happening now, and would like to know if the host/conductor would be capable to compete with the kids... But, first I must disclose I have never gone to school in U.S. or any other English speaking country and learned English as third language at an academy. So, guilty. What brings me to post is the mystery when the host tells several pronunciations of the subject word. WHAT is the host reading to give different ways to pronounce the word in question ? Is the host reading this senseless <censored> I think is called phonemes ; a few of them to tell the kid the ways it can be pronounced ? And sad to see how the words selection is being shifted to other languages; either because they are running out of words in English or to make it beyond difficult. Today they presented a Japanese word and a Korean something fitted in the contest. Horrible. Does this spelling thing exist in other languages ? Thank you.

groan!

I am so sorry, Memsahib! My elephant has been given a stern warning and will avail herself of the proper elephant waterclosets in future.

OP probably lacks sufficient education to avoid such simplistic stereotypes

A poundal is the certain force - or so my dictionary reckoned - to accelerate a pound of weight by one foot per second per second. (written some years ago)

Brave (Chrome variant with Google's tracking elements removed) is my go-to browser with Privacy Badger and uBlock Origin extensions. It has a bult-in optional browser-level VPN. That works pretty well for me. Just got a new i5 Win11 laptop, W11 is a bit of a privacy nightmare in terms of MS putting ads in the new Outlook email, I'm seeing. Seeing the email-tyle ads as the last straw, I've just bought Proton VPN and email app services. It works at whole-system level and, apparently, '5 Eyes spying cartel' snooping resistant as well that US/UK are part of, so hopefully, it's up to the job at the lower level I want it.

I haven't, but I'm very interested in anything you might have to say about it. Not to say I'm not enjoying the discussion on local realism and the concept of reality. (As well as the ongoing intellectual feud between Moontanman and Dim.)

Yeah, hunter-gatherers are the problem. Sigh

Who cares what you want? Did you check with the African bushmen to see what they want?

Why do you pick on Africans? Their impact on climate change has been negligible in comparison to those accustomed to riding in modern air-conditioned automobiles.

I was thinking about your comment on nitrosamines and had prepared a response to Charon Y containing evidence that mouthwash is detrimental to NO metabolism, and also stating that there is overwhelming evidence on the harmful effects of processed meat and meat consumption in general on health. However, as you indicated, we are far off topic, so I will not post my original text. Thanks for the reminder and for answering the original question.

Is that the causative agent, or just a symptom/side-effect of it? (or both) Education may mean knowing about birth control, but it also might just be an artifact of possibly having a white-collar job, and not needing to pump out a bunch of kids to work the land. Education also might indicate decent health care, so you don’t need a high birth rate because the infant mortality rate isn’t so grim. I think the point is that you haven’t clearly communicated anything specific. You haven’t mentioned contraception, so how does one know you are advocating this?

I figured that, but my navy time pushed the warship designation to the top of the list.

I was there late ‘95 through early ‘98 in the TRINAT group (TRIumf Neutral Atom Trap), which was established around ‘93, I think. They needed an atom trapper, which was outside the expertise of the people there. The other postdoc had learned a lot about it, but their background was nuclear/particle. We trapped some radioactive potassium isotopes, and once that system was running they could focus on the nuclear physics experiments. Since I helped build the apparatus my name was on a half-dozen papers after I left. I think Otto is looking for actual engagement, not rhetorical questions that have only a passing relevance to the issue.

Hehe. Acronym universes collide! (DDG is Duckduckgo.com)

I'm on an older chrome book and the ads are off the hook!

Through worldwide EDUCATION. It does seem that population is declining already in the most developed/educated nations. We need to target other areas of the globe. No living human (man, woman, boy, girl or baby) on this entire earth should ever be deprived of a modern well-maintained home, sufficent nutrition, decent clothing, electricty, clean running water, clean air, proper indoor pluimbing, Internet, necessary means of transportation, modern healthcare, a decent education, a means of making a decent living (including being a housewife) and to live free of squalor, crime, violence, unlawful drugs rodents and pests. I want to see an African bushman type society no more. It's time for those people to throw away their spears and ride in modern air-conditioned automobiles (preferably powered by green sustainable energy) too and on well-maintained paved modern African roads. I want no more elephant feces or garbage littering the streets of India.

The best documented effect of nitrites in the diet is their reaction with secondary amines to produce nitrosamines which are carcinogenic. Meanwhile, back at the actual question, it's ethanol.
