Now I can buy (for a lot of money):
A 16" (0.41 m) diameter spherical stainless steel vacuum chamber with a mass of 83 lbs or about 37.6 kg.
A sphere of stainless steel 0.41 m in diameter, which has a mass of about 281 kg and
A sphere of lead 0.41 m in diameter, which has a mass of about 399 kg.

These all have the same volume, are quite impervious to air, yet have quite different masses and hence weights.
Of course the vacuum chamber would weigh about 40 g LESS when evacuated.

Please explain how these objects which displace to same volume air have such different masses and weights?
Two of the objects are made from stainless steel, so how can they differ in weight.
Also where are some references, so we can read more on Sceptimatic's Theory of Gas, Gravity and Everything Else? 
or is this theory only contained within the awesome mind of Sceptimatic, like Poppy Fisiks in his marshmallows.

In real science, if someone comes up with a new idea it is commonly met at first with scepticism (eg cold fusion, etc), it is not until the the findings are verified by others are they accepted.
What are you trying to say?
Why do the hollow stainless steel spheres (one hollow, one solid) and the lead sphere weigh quite differently, when they must displace exactly the same amount of air?
One hollow and one solid should answer your question. One is already full of atmosphere.
Get real, I did say that if I evacuated (meaning removed most of the atmosphere) the hollow one, it would weigh 40 g less.
You can't evacuate it. It still has air in it and will always have air in it unless it collapses.

So when you are on a skateboard and push against the wall you move away by displacing air ? :D
Yep, you move away by displacing air. The reason you can't grasp that is because you're not thinking on the right lines.

Here's a tip. Arms bent and energy applied to the wall, requires a displacement of air, just for that to happen. Once that has happened, then all of the mass has been pushed against the atmosphere, compressing it and causing it to come back around the mass to create equal and opposite reaction to action.

Quote from: aisantaros on June 14, 2016, 08:07:37 AM
you know you can push against a mass whether it is fixed or not, you could push against a medicine ball when you throw it.
Yep but the only way you can push against a medicine ball and receive a reactionary force back from it, is either when that medicine ball is under atmospheric clamping on the ground which creates a friction on that ground as well as against atmosphere, or your own energy holds that mass of medicine ball, up. You have displaced the amount of atmosphere that the medicine ball repels from its mass and that's  the pressure of atmosphere bearing down onto your ball that you have to resist with your energy.

By throwing this medicine ball horizontally, you will have to move it from one filled atmospheric place to another, then another and another, depending on how much energy you put into the throw. All that atmosphere reacts against your ball until you release it - or to put it simpler - when your energy of push does not count anymore.

So from what you said, I assume that Newton's third law does not work underwater, and that heavier objects displace more atmosphere regardless of their shape. Ok.
Heavier objects are only heavier to us solely because they displace more atmosphere. The more atmosphere that is pushed into by whatever object, the more that object will weigh on a man made scale.
It's about the density of the object against the atmosphere. Basically repelling it rather than absorbing it.

Stop making stuff up. How does a hollow metal box displace less air than one that isn't hollow? Do you have any evidence for what you're saying? (Rhetorical question, I know you don't)
I'll take this as you trying to play the wind up merchant. Don't bother me with your drivel.

Are you taking the piss or what? "Air" apparently means something entirely different to you than it does to everyone else. What happens when there is no air?
No atmosphere and no movement.

So your theory is wrong, as has been demonstrated by countless easy to replicate experiments.
My theory is not wrong and there have been no experiments showing anything like what I'm talking about.

It's slightly sad. No; in fact it's fairly scary that people like you cannot grasp logical common sense, even after being explained to.
Your reliance of equations that add nothing and prove nothing in the context of logic, is naive and silly.
You carry on being naive and you'll learn nothing.
What you know now, is a lot of misdirection, either deliberate or, in some cases, simply borne from naivety.

Just possibly the reason "that people like" us "cannot grasp logical common sense", is that to us it does make the slightest bit sense, logical, common or otherwise! Sorry about that.

If you come up with ideas that are so different to those general accepted, you have to give some experimental justification of them and allow your "theories" to be tested.

All sorts of hypotheses might seem to be logical, but that in no way makes them true, of justifies our accepting them as describing the real world.

So, don't get on your high horse and label all who have different ideas idiots. If you can't justify your ideas with more than their being "logical common sense", then they are worthless to anyone.

One test of a valid theory is its ability to predict what would be expected in particular situations. I ask you why certain spheres would have different weights, and you seem insulted that anyone as lowly as myself would dare question you superior intelligence.

Maybe compared to you I'm a nobody, so be it, but it's no way to get your ideas accepted!

You beat me to it; All though I was going to use a cubic inch of granite and a cubic inch of wood, if it is displacement of the air that creates weight, what happens when you drop them in the water? ???
oops this is a derail.


Have a think about it.
Let's go back to the styrofoam and lead as an instance.
Equal sized blocks placed in water; what happens?

The lead block sinks and the styrofoam floats high on the top. Why?

The Lead block creates a massive resistance against the atmospheric pressure but cannot use the water as a leverage to resist it because the water isn't dense enough to act as a leverage and so the Lead, sinks.

The styrofoam is mostly air and is already part of the atmosphere, so very little of it has to use the water as a leverage to resists the pressure upon it, so it floats high in the water.

You can take that same block of lead pounded it out roll it out flat very thin, turn the edges up place it gently Into the water and it will float. What does the shape of an object have to do with this weight?
Once you turn up the edges you then create a massive atmospheric area. Think about it.

I place the block on a scale it's weight is X.
After shaping place it on a scale it's weight is still is x.
The atmospheric area has not changed.

I don't think I would carry on about common sense.... as in your world of "observation" we could fly simply by flapping our arms or kicking our legs. More or less swim through the air.

We would have to have 100 horsepower fan motors just to create enough power to move air in the bed room. However, you really wouldn't want to get in the way it it, as the movement of that much mass would be like getting hit by a title wave.

Spring breezes would be deadly events, most of our time would be spent under ground.   

I could go on with this ridiculousness but I don't have the time.

Just look at the polls...you need to face reality one day for your own advancement, otherwise you will be stuck like "this" for good.

How is any of what you say "common sense"? You just come up with ridiculous explanations that require that we throw experimental observations out of the window, that's extremely backwards.
You aren't throwing experimental observations out of the window. What you go with has not been experimentally observed, physically. What you observe is what you read in mainstream books and what you hear by those that parrot what the parrots parrot. And so on.

Actually, that sort of thing is confirmed experimentally all the time in wind tunnels.

Newton's Third Law

Identifying Action and Reaction Force Pairs

A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions!

Examples of Interaction Force Pairs
A variety of action-reaction force pairs are evident in nature. Consider the propulsion of a fish through the water. A fish uses its fins to push water backwards. But a push on the water will only serve to accelerate the water. Since forces result from mutual interactions, the water must also be pushing the fish forwards, propelling the fish through the water. The size of the force on the water equals the size of the force on the fish; the direction of the force on the water (backwards) is opposite the direction of the force on the fish (forwards). For every action, there is an equal (in size) and opposite (in direction) reaction force. Action-reaction force pairs make it possible for fish to swim.

Consider the flying motion of birds. A bird flies by use of its wings. The wings of a bird push air downwards. Since forces result from mutual interactions, the air must also be pushing the bird upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air (downwards) is opposite the direction of the force on the bird (upwards). For every action, there is an equal (in size) and opposite (in direction) reaction. Action-reaction force pairs make it possible for birds to fly.

Consider the motion of a car on the way to school. A car is equipped with wheels that spin. As the wheels spin, they grip the road and push the road backwards. Since forces result from mutual interactions, the road must also be pushing the wheels forward. The size of the force on the road equals the size of the force on the wheels (or car); the direction of the force on the road (backwards) is opposite the direction of the force on the wheels (forwards). For every action, there is an equal (in size) and opposite (in direction) reaction. Action-reaction force pairs make it possible for cars to move along a roadway surface.

Number of objects in the examples: TWO.

Number of objects a rocket is: ONE.

Number of sock-puppets trying to prevent you from comprehending this simple Fact: INFINITE.

Try again!

Number of objects a rocket is: TWO.

1) The rocket.
2) The TONS of burnt fuel ejected at 2,000 m/s or more.

Papa, go stand in the corner and repeat 2,000 times "Gas has mass! Gas is matter, so gas matters" - there that's easy to remember!

Papa can't count, Papa doesn't know the equation for thrust ~ (mass flow, exhaust velocity, and the pressures)

So, Papa knows nothing of rocket theory, no matter how much his partners in grime try to prop him up!

You beat me to it; All though I was going to use a cubic inch of granite and a cubic inch of wood, if it is displacement of the air that creates weight, what happens when you drop them in the water? ???
oops this is a derail.


Have a think about it.
Let's go back to the styrofoam and lead as an instance.
Equal sized blocks placed in water; what happens?

The lead block sinks and the styrofoam floats high on the top. Why?

The Lead block creates a massive resistance against the atmospheric pressure but cannot use the water as a leverage to resist it because the water isn't dense enough to act as a leverage and so the Lead, sinks.

The styrofoam is mostly air and is already part of the atmosphere, so very little of it has to use the water as a leverage to resists the pressure upon it, so it floats high in the water.

You can take that same block of lead pounded it out roll it out flat very thin, turn the edges up place it gently Into the water and it will float. What does the shape of an object have to do with this weight?
Once you turn up the edges you then create a massive atmospheric area. Think about it.

I place the block on a scale it's weight is X.
After shaping place it on a scale it's weight is still is x.
The atmospheric area has not changed.
A flat piece of metal is easily unbalanced by the water. A turned up edge of the same metal allows atmospheric pressure to push down on it  against its resistance and thus, stabilizing it.

Why do you even bother asking someone questions who believe that you swing a swing with your legs by air resistance?

I hope he is right, if he is tonight I am going to fly like an eagle :D

The fact that you believe you can fly because of what I said, means you don't understand what's being said, or are simply making sure truth is suppressed.
It doesn't matter which.
I'll try and help you out a little bit - assuming you are simply clueless or naive.

The swing seat enables the person to keep stay in the air and keep moving by kicking into the atmosphere. The rest of the body plays aerodynamics.
Take a look at a person on a swing and see what's really happening.

A bird uses its wings to push down on atmosphere to create lift, but as soon as the energy is spent in creating that lift, the wings twist to vertical to slice through the air to create a path of least resistance.

The person on the swing kicks out their legs to scoop atmosphere then straightens them out to create a path of less resistance. This is what keeps the momentum.

How you think it can be done without the aid of atmosphere is the most baffling thing, ever. The only way this can be is for reasons I explained earlier.

My guess is that you're a star trek lover or something like that. This would explain why you buy into the nonsense that the sci-fi writers spew out.
Maybe you are simply dis-info. Who knows?

Rich man at a low ebb on a flat Earth forum defending anything mainstream. Hmmm. It's baffling.  ;D
