Gravity

[MattMooradian]

But I think Jesus was quite aware that wasn't going to happen.

I agree. Jesus knew that none of his Christian followers would have sufficient faith. Moving mountains would be difficult, but why can't we move pennies across tables? Certainly, Christians should have that much faith, by now? I believe we are all missing something in our Christianity, and our poor faith is the results. I can only conclude that every Christian's faith is smaller than a mustard seed - that's very, very tiny.

Since faith is not material, it is indeed smaller than a mustard seed. But as in the case of St. Francis of Assisi, who barged into a Muslim Caliph's palace and demanded to see him for a test of faith, there are those who have great faith.

St. Francis did this when Europe and the Muslim world were at war. The guards reportedly came to the Caliph, and said "would you like us to kill him?"

The Caliph said "no, I gotta see this guy."

St. Francis suggested a test of faith between him and the most prominent Muslim cleric. The deal: Fire up a furnace and each of them jump into it, calling on God to save them. St. Francis offered to go first.

No one wanted to take St. Francis up on it, and the Caliph was so impressed with his faith in God, he released him unharmed.

St. Francis

St. Francis certainly had great faith.

 

[Joseph77]

St. Francis certainly had great faith.

"Francis set out on a mission to restore Jesus Christ's own, original values to the now-decadent church."

Gravity, what can we do with it? Could it be used for other things like making electricity? Is there anyway we could take advantage of it? Is gravity the same all around the earth?

Gravity, Isaac Newton is the man i think with his laws of gravity. Also Einstein with his theory of relativity.
I think Newton worked out that gravity at sea level has an acceleration of 9.8m/s2. This decreases as the further from sea level we get.
From aerospace to static structures this magical number is used a lot in engineering. But we are often working against gravity.

Probably the best example of exploiting the power of gravity is a hydro electric system. We have one, the snowy hydro scheme, but cos we don't have much water here it is very limited. America has heaps of them cos they have the great lakes with a constant mega supply of water.

Many agricultural water systems are gravity fed. Some spray painting guns are gravity fed.

There is a place known as gravity hill out near hanging rock around the Macedon/Woodend region.
The road is called Straws lane, u could find something on youtube probs. I've been there a few times and seen cars roll up hill, balls roll up hill, we even tried to see if water would go up but it was so long ago i don't remember if it did.

Here is a bit of trivia... What causes gravity??? No cheating with googles

Well....

if you get some baked potatoes, some good well done meat, maybe green beans and mushrooms,

pouring some hot gravity over a plateful for a meal can be delicious !

Actually, Newton's Laws were regarding motion. Because he not only predicted movements due to gravity, but explained why it works that way, he produced a theory of gravitation, not merely a law. Laws predicted things. Theories predict and explain things. This seems odd to most people, who are unfamiliar with the scientific meaning of "theory."

Yes.

This decreases as the further from sea level we get.

Yes. So people aboard the ISS are not free of gravity; they experience microgravity.

Lots of mountains. And in the Pacific Northwest, lots of snow at the high elevations in the winters, so really strong, young rivers which are most suitable for hydroelectric.

Fun with optica illusions. You can build room like that.

The honest-to-God answer is "we aren't exactly sure", but the practical answer is that mass distorts space. You can build a two-dimensional analogue, using a rubber sheet tightly stretched on a frame, with a heavy sphere on the sheet. It distorts the sheet, and rolling marbles across the sheet, you can simulate many of the motions of planets and comets around the sun.
