## Understanding the "God" Concept

You changed the object from 'concept of God' to 'God'. The concept in itself can explain the building of temples, churches, etc. Condition is that those who use the concept believe that something outside the 'God discourse' match with this concept. Certainly, 'God' exists is a concept (however, in different cultures, very different concepts), but that does not proof God's existence. As Phi for All already said, there is a concept of unicorns, but that doesn't mean they exist outside the discourse about them. And if you think that the this is not valid, because the 'God-concept' is very special, you are nearing the ontological proof of God's existence. Hmm. Interesting difference you make here between 'being real' and 'not existing'. May I propose some other distinction? Things exist physically, if they play a direct role in causal relationships, independent of how we we talk about them. Things exist conceptually, if they are useful to describe the world around us, which includes things that exists physically (example: laws of nature), but also human behaviour (examples: marriage, stories, free will). The point is that we can refer to observable entities, to show what we mean with these concepts. And I think 'unicorns' and 'God' do not belong even to the conceptually existing things, because we cannot refer to observable entities.

## Dimensional significance of volume/area ratio

Absolutely. Adding up thin shells to create the full sphere is actually a very common technique to access the volume, i.e. $V(r) = \int_0^r A(r) \, dr$ Well, picking up on the integration example: The average distance <r> of a particle from the center in a sphere of radius R is $<r> = \frac{1}{V(R)} \int_0^R \, r \cdot A(r) dr = \frac{1}{V(R)} \int_0^R \, r \cdot 4\pi r^2 dr = \frac{1}{\frac 43 \pi R^3} \left[ \pi r^4 \right]_0^R = \frac 34 R$ (modulo typos: Tex does not seem to work in preview mode ... EDIT: And apparently not in final mode. The result in the calculation above is <r> = 3/4 R). There is a general tendency that the higher the dimension, the more likely a random point in a sphere lies close to the surface. There is a famous statement in statistical physics that in a sphere with 10^23 dimension, effectively all points lie close to the surface. In all sensible definitions of volume and area I am aware of (at least in all finite-dimensional ones), volume has one more dimension of length than area. Hence, their quotient indeed has dimensions of length. I don't think the quotient itself has a direct meaning. But there are theorems like that a sphere is the shape that maximizes the V/A ratio for a fixed amount of V or A. I already commented on the dimensionality. But I still encourage you to just play around with other shapes: Cubes are the next simple thing, I believe.

## Space-time molded by the mass

Popular explanatory diagrams often show huge amounts of curvature, whereas in reality even Jupiter sized planets cause very mild levels of curvature. The original experimental proof of the curvature at the surface of the Sun sought a deflection of 1.6 seconds of arc for grazing light. The masses required to create Swartzchild conditions are many times larger. Perhaps Marcus could comment on this or Mordred (if he comes back). This is really their baby.

## Florence the Hurricane

No you are mistaken, the air flows do not cancel each other they complement each other, the lessening of the hurricanes winds is caused by things like ocean temps and wind shear. https://image.slidesharecdn.com/cdb9bde1-df1c-4325-8810-fd99ac44d65e-151230203327/95/tropical-cyclones-presentation-19811988-4-638.jpg?cb=1451507711

## natural phenomena should be not named after people

Fair comment. I apologise if I misunderstood and misrepresented what you said.

Eloquently put. I can't really say I disagree with anything.

## Understanding the "God" Concept

Do you use the term Mother Nature? Many theists, atheists and agnostics use the term, knowing nature to be true. However, like hot or cold, nature is not a thing unto itself... it's a property of other things. The planet and the universe. Free will does not make water hot or cold and despite all of the available variables we can impose, it can only be in one state at any given time. Therefore neither can be wrong. Each have a time and a place for us at different times. It's when we put a face on it, or deny it's existence entirely, is were we go wrong. Hence my position as an agnostic. Jonah being swallowed by a whale is a bunch of crap, as is the great flood, but Ecclesiastes 3:1-8 is wise. There is good and evil in everything and that is where free will allows for us to find or lose ourselves as individuals. Most who grasp the concept of nature understand grandeur, beauty, retribution and destruction (to name a few). These are the identical things theists advocate when they speak of god. The difference being, nature does not play favorites, pass judgements nor listen to individual prayers. We understand that when we intervene with nature by actions, there are consequences. Nature does not show retribution for our thoughts, but sometimes for our actions, yet moreover for reasons we may never understand. This we know to be true, as well. An eight year old girl told me once "Big fish eat little fish and that's just the way it is" It's true, wisdom often comes from the mouths of babes. Thank goodness humans developed morals, because we'd otherwise be cannibals or ruthless cold blooded killers. When we apply these morals to nature, we understand there's no need to do certain things, even though we can. In that vain, there's liitle to be conquered or dominated. We accept that some things should just be and it has absolutely nothing to do with any of us, other than being a part of the big picture. I'm a follower of Ed Ricketts, as was John Steinbeck, Joseph Campbell and Salvadore Dali, to name a few. His philosophy was wrapped in the science of the ecology... the economy of nature and like Ecclesiastes, a time and purpose for everything, how necessary voids are filled, that things may be reborn and how species may co-exist.

## Florence the Hurricane

Hurricane winds blow in different directions at the top and ground level. Think of it as a two whirls, going in opposite directions changing directions in the eye as the surface winds spiral up into the stratosphere and back out over the lower cloud decks. It is an odd effect, I've seen it many times, the whole hurricane is strange compared to normal thunderstorms yesterday it was almost dead calm here, almost suffocating, today the wind was blowing five to 10 mph but always in one direction as the eye approaches the wind will pick up to and beyond hurricane force and continue from the same direction, then the eye will pass over and the air will be dead calm and often very sunny then suddenly the wind will start up directly to hurricane force but from the opposite direction. You have to be careful about going outside when the eye passes or you'll be caught be the full dorce of the storm before you can get back inside...

## CAN there be too many engineers?

If you take a narrow view-- as in which field of engineering designs which products, there could be an excess in some fields now and then. However, one of the value-added aspects of engineering is that you learn to approach problems and find solutions. It can demand considerable creativity. The engineers with creativity and the necessary education in the science and math needed to apply the creativity are very rarely without well-paying and fun work. Of course, Engineering is not the only field that benefits from creativity-- but its creativity coupled with knowledge of science and math that makes fields like engineering stay in demand.

## Understanding the "God" Concept

It still sounds no different to me than saying unicorns are real because of the causal effects they've had on so many young girls growing up. If you use the most common definitions of god(s), as well as the scientific definition of evidence, this is nonsense.

## Banned/Suspended Users

Kafei has been banned at his request. We thank him for cutting the red tape, since it would have been a few hours more before other mods could have weighed in and agreed to that action. Also for the lesson that claiming you haven't broken any rules means nothing when you don't actually know/understand what the rules are.
