1. ## Science Photographer of the year

https://www.bbc.co.uk/news/in-pictures-56016031 Interestingly there are a couple of photos about the use of solar power in the list and also several other environmental science subjects.

2. ## Proposal: ASD and ToE

Introduction The ASD is an acronym for Adaptive Semi-Determinism, which will be defined and explained starting on next section. I made threads or topics regarding the ASD thing on other sites in past, but nearly have forgotten all about it until today. The reason for this topic is that I noticed there is no concrete case (eg. Being complete) of unified theory of everything (ToE) of everything to define and explain everything or even each individual sentient being for that matter due to qualia or freewill. For any action such as an act of smoking a cigarette overrides the logic r

3. ## Can infinities exist in nature?

How is that a paradox? You expect a certain behavior based on assumption(s). If the system doesn't behave as expected it's not because theres a paradox, it's because your assumptions about the system behavior are wrong.

4. ## Can you help me about these calculations?

Since this was originally posted two months ago: We have aBaCl2(aq)+bK2SO4(aq)→nBaSO4↓+mKCl(aq) Looking at that I see that there are "a" Ba atoms on the left and "n" Ba atoms on the right so we must have a= n. I see that there are "2a" Cl atoms on the left and "m" Cl atoms on the right so we must have 2a= m. Is that there are "2b" K atoms on the left and "m" K atoms on the right so we must have 2b= m. Finally I see that there are "b" SO4 ions on the left and "n" SO4 ions on the right so we must have b= n. That is, we have the four equations a= n, 2a= m, 2b= m and b= n. That

5. ## Can infinities exist in nature?

Except what you're saying is, it's infinite because it's infinite (I'm duty bound to point that out). 😉 Seems to me that infinite is just another way to say "I don't know". I think a more interesting question would be, can a paradox exist in nature? Then the answer to my question is yes, but only in people.

8. ## Is there a proposition known to be undecidable?

Hi again. Thanks for explaining your requirements. Sadly, I'm not an expert on higher order logic and it seems unlikely I'll have time to become familiar with it over the next few months. So I'll be bowing out of this conversation. Sorry I couldn't help. Best wishes to you, bye for now.

9. ## Crashing into Andromeda

I would put into consideration a different contribution made by Hubble prior to his Law. In 1924 he discovered Cepheid variable stars in Andromeda, which he was able to use to show that Andromeda was far outside our own galaxy, and not a part of it. While there had been debate about this., his observations were the first to provide exidence that the cosmos was much more vast than previously suspected and extended well beyond the Milky way.

Einstein and General Relativity showing how mass/energy density warp, curve, twist spacetime. Person? Carl Sagan who personally sparked my interest in cosmology but sadly too late to really do much about it except learn. As he said Cosmology/astronomy is a humbling and character building experience...from that unforgetable description entitled "Pale Blue Dot"

11. ## Why would an athiest not believe in religion?

Personally I have nothing against religious people, or religion for that matter. In a vast majority of cases in this day and age, I believe people use it and practise it, more as a comfort entity then anything else, and as a wall against the scientifically based conclusion that death is it...it is final and the end. That worries many people imo, and religion gives them that inner warm fuzzy feeling that upon their death, they will be magically transported to heaven or its equivalent. There are many good decent religious people in this world that mean well, and truly practise the basis of

The universe is finite. This follows from the law of conservation of energy (once the stars must burn all the hydrogen), as well as from the second law of thermodynamics. And then, either our universe is part of something larger (the multiverse), or we must accept the existence of God. Which point of view is closer to you personally?

Must be rather nice to see that the Dems never do that type of towing the party line...
