I was checking to see what another poster understands about gravity.. and got my answer.

I'm not sure but I don't think there are many (any?) professional scientists left who will post on a biology thread or segment. I'm limiting mine to some data checking.

Tech threads may be ok. Even though Biblical literalism would require a re-ordering of physics, geology and astronomy; for some reason they seem to be left alone.

Given your examples I am not sure how well you understand gravity theory either.

I notice how you passed judgment on metmom and yet deferred your own answer for a 'gravity expert scientist' to show up and explain it all away.

Well If you are a genetic scientist, then you should have the basics of science down pat. So here is one that should be an easy floater for you to hit out of the ball park.

Why would small amounts of helium (dispersed and not contained) display different properties or behaviors than the helium gas when concentrated and contained in a vessel such as a balloon?

Did you need her to say something about permeable membranes or something? The helium part of a your question wasn't only about gravity. My question to you was & like you, I was checking to see what another poster understands about gravity...

When my sons were little, we seemed to go through a phase where they had helium balloons on a pretty regular basis. After awhile, the balloons would get to the point where they just hovered above the floor. Looking at some of them one day, I wondered what would happen if I took them into the basement. What do you think the balloons did after I took them there? Do you think they hovered over the basement floor, as they had over my living room floor or do you think they rose to the basement ceiling? There was a slight difference in temperature. The basement was slightly colder, though I didn't check the difference with a thermometer. Colder could have caused the balloon to shrink a bit, but I didn't notice a change in size. I didn't measure for it, as size wouldn't have added any more helium molecules to the balloon. So anyway, what do you think those balloons did?

Understandable, because a lot of them look more like food fights than "discussion". From my POV, part of the reason there is so much discord in the area of biology has to do with the fight about making this "soft" science into a more "hard" science. IMO, confusing rigidity with strength is an error.

The fact that so many FReepers managed to get through HS without learning basic scientific method is the fault of our education system. Telling students to keep their world view to themselves, essentially, "sit down & shut up, while I teach you what you need to know", is an instance of trying teach what to think, instead of how to think. Learning how to think is much more important than all of us knowing what to think, if our civilization is to advance.

You do your thing & other people do theirs.

You're telling this to the wrong person, trust me.

Part of me is thinking along the order of screwing up the threadjacking in progress. Allowing that to happen would probably be the better part of valor. Hitting post, proof that I've yet to be fully cured from tilting at windmills on occasion. LOL
