You've obviously never used a cutting laser.

 

According to the EPA, nuclear subs use "steel, water tanks, and polyethylene" for radiation shielding. Probably weighs a lot less than lead (and having less mass makes the sub more manuverable).

The polyethylene is shielding for the neutrons. They go right through lead like it isn't there at all. The lead, if any, is for the gamma rays they go right through the polyethylene and need some element with a heavy nucleus to attenuate them.

The ideal radiation shield has both.

The power source (car battery) has internal impedance.

What this means to you is that when any load is placed on the battery its voltage drops.

The bigger the load the more it drops. A starter is a very significant load and thus the voltage drop is significant.

Anyway if you are running the starter the engine is not running and the alternator is not trying to hold the battery voltage up.

Even touching the brake lights will dim the headlights when the engine is not running just not as much as the starter.

Is it likely that one could produce a salt KSbFeO4

Any ideas?

Suppose [math]1+2+4+8+\cdots[/math] exists. Call this sum S:

 

[math]S\equiv\sum_{n=0}^{\infty}2^n[/math]

 

Multiply S by two:

 

[math]2S = 2\sum_{n=0}^{\infty}2^n = \sum_{n=0}^{\infty}2\cdot2^n = \sum_{n=0}^{\infty}2^{n+1} = \sum_{n=1}^{\infty}2^n[/math]

 

The last expression is just the original sum sans the zeroth element: [math]2S=S-1[/math] and thus [math]S=-1[/math].

 

See http://en.wikipedia.org/wiki/1_%2B_2_%2B_4_%2B_8_%2B_·_·_·

Which is just another proof that any number multiplied by infinity looses its identity...

Similar things happen to any matter that falls into a singularity.

The problem here is that few understand the ambiguation that happens when infinity is used.

The real answer to the original post is ANY NUMBER.

So 42 is just as valid as any other.

The truly tragic part of this is that I cannot pick lotto numbers by summing all numbers... I would win every time.

how does the body create electricity? i know we use it to think, and move, but what and where creates it? biology isnt realy my subject, even though how interesting it is, i am realy interested in energy and electricity production though. and im curios how we derive electricity, though we dont have any copper or ceramic-titanium mixes in us{as far as i know}

A little trick of pumping sodium and potassium ions (atoms stripped of an electron) in and out of cells. This creates a charge imbalance that is imposed across the cell walls that conveniently happen to be good insulators.

That is the voltage, when a nerve wants to fire things move around (the current)

and that sparcks up another q, how does the atmosphere make electricity, or the clouds. like lightning. is it the water in the clouds and the movement adjacent to the magnetized earth? i know this isnt really biology, but i thought id ad that on and see if i can kill 2 birds with one stone.

In a single word friction.

It is slightly more complex than that as the friction works better between layers of air with differing humidity or temperature.

Then there is a small current falling from the sky or climbing into the sky depending on you latitude that is the natural implementation of the aurora's.

That current is a result of the solar wind of charged particles and earths own magnetic field.

Lye & Sugar when heated together are a source of Carbon Monoxide.

You can check wikipedia under Carbon Monoxide

Not recommended unless you REALLY WANT Carbon Monoxide.

ANYWAY hydrogen is so fun why would you want something else.

Also if you get the Lye solution in an eye the damage is permanent.

Now that I have cut the red wire and the green wire and changed the combo which wire do I reconnect first?

Ya know if you just balanced a bunch of pencils point down on a hard surface, you could save yourself an enormous amount of grief.

It is much easier than perpetual motion, but still is impressive.

Oh I forgot to mention I am only reacting 200uL of stuff.

So the big explosion might be able to tip my 400mL Teflon beaker over.

And the exothermic part I am reacting at the rate of evaporation of the Antimony PentaFluoride which is thawing out slowly.

I plan on the whole reaction of the 200uL taking at least a day.

Endothermic yes but only a temp rise of a few deg.

~minus

well of course Paulii said this

 

it has nothing to do with time but all to do with space

 

Actually unless a sub atomic particle can occupy two wave functions at the same time... time it has everything to do with wave functions.

And thus my hidden dimension explanation is plausible, although quite unlikely.

I just like to look for simple reasons for all unusual behavior.

~minus

once again, minus, please don't try this. it's just not safe. any slight impurity and this stuff will explode, showering you with vicious acids and fumes

1) I would be about a mile away when the Antimony Pentafluoride melts.

2) I cannot afford to do this, even the raw materials far exceed my limited research budget.

3) If I do find a way to procure the stuff, all of the stuff (win the lotto) I really do not like HF... the stuff scares me... I've used it but I don't like it.

I think I will stick with Nitrogen Monoxide and Carbon Monoxide and make my Iron Nitrosyl Carbonyl and the like.

Just want to keep the mind pushing the envelope.

What I really want to know is: what would be the properties of Iron Fluoroantimonide, would it be Iron (II) or Iron (III) would it be ferromagnetic

and similar questions.

I would be happy if I could get Iron(???) (Halogen of choice) antimonide.

Thanks for your concern.

Spin is an attribute not a motion.

spin is a movement regardless

Then it should have precession.... NO?

Wave function could be a dimension that is quantized at a level that includes it largest dimension ... too many possibilities for my little brain.

explain further

Wave function is a quantized set of mutually exclusive states... they might as well be location in some very small quantized direction, thus the Paulii exclusion principle could be nothing more than "no two physical objects can occupy the same place at the same time"

Spin is an attribute not a motion.

I believe that Isomeric Transformation changes in nuclei can happen without movement.

change without movement ? how

Wave function change

Well at least only movement in wave function... is that a dimension?

~minus

NO

You can't do that. The reason is that you can reorganize a conditionally convergent series to give any answer you want according to the Riemann series theorem.

Cool then we are all right *GROUP HUG*

This kind of math certainly explains global warming and coming ice age at the same time.

Those climate guys just need to keep adding those numbers up and they can give us any answer we are willing to pay for...

It is still 42 as is global warming.

Wow that just exceeded my budget.

Liquid HF... now that sounds to me more scary then the Fluoroantimonic Acid...

That at least I had hoped to do at atmospheric pressure (very slightly positive) in a non sealed (covered) container.

I was hoping to produce the HF by the reaction of Antimony Pentafluoride with water in situ as it were in very minute amounts.

Thus I could control the rate of the whole shebang with the vapor pressure of the Antimony Pentafluoride by its temperature.

All of the heat liberated by the chemical reactions being Isothermal to the Antimony Pentafluoride.

The back fill of Argon is a great idea and an obvious oversight on my part.

Thanks,

This thread follows a thought experiment I just completed.

If time were to be motion in a Cartesian coordinate, then the cosmic speed limit of C as proposed by Einstein would include that motion.

As such the effects of relativity on space time might be nothing more than the bounding of the vector of all motion in 4D space to C.

Unfortunately I do not possess the math skills to see if the equations of relativity say just that.

How about it?

Or am I just trying to oversimplify things again to get them to fit into my little head.

I vote static electricity...

Is this worse in the winter?

Great suggestions: Humidifier, antistatic laundry stuff.

Take a fluorescent bulb to bed in the dark. If you see flashes in it you have static electricity. Move your legs around in the blankets while holding one end.

That will answer the Inside/Outside your head question right off.

Um I am not sure on the physics of your answer but I am pretty sure that the answer is a mathematical one that has nothing to do with gravity, black holes, or Hawking Radiation. That said I would have to agree with Shadow that if you add all real numbers for every positive real number [math]n[/math]there must be a negative real number [math]-n[/math] and since [math](n)+(-n)=0[/math] I would assume that the series of all real numbers would be 0.

Sorry about the bad humor...

I think the correct answer is the limit of N as N approaches zero.

Who is to say that the universe is expanding...

Perhaps we are just shrinking in a fixed sized universe.

Entropy...

I cite my checking account balance as proof.

Anywho how can something that has no boundaries and no center be said to expand,

You don't get the luxury of a reference point.

One only gets to say that time and space are working together in a way to make things far away appear to be moving away from us.

So someone calls it expansion, not bad for the lack of a better word.

I don't know but the virtual photon- Anitphoton pairs that form near Black holes have a preference based on gravity...

that the negative photons tend to fall in and the positive ones tend to radiate.

Thus the Entropy of a black hole as per Hawking...

As such because of gravity I am quite sure that the number cannot be exactly zero so I vote for 42 also.

You are after all adding up all numbers in the presence of gravity.

~minus

Yeah that makes sense...

It is hard to imagine Fluoroantimonic salts, at least ones of (II) or (III) configuration.

So this brings us full circle...

Are there any Fluoroantimonic salts?

Is there a place to look such things up at?

~minus

If I do perform this It will be done out of doors far distant from any living being.

The weather well understood.

I Would Be a great distance away when the solid (frozen) components thaw out and begin their irreversible path.

As the vapor pressure of the Antimony Petafluoride will gradually rise...

If such a salt existed wouldn't I be able to look it up somewhere, determine a few of it's properties. That would save me quite an expense and perhaps direct me in a more sensible direction.

Thanks,

I was thinking to place in a wide mouth teflon jar three small teflon beakers...

One holds Antimony Pentafluoride, another Iron Hydroxide, the last water.

The vapor pressure of the former should cause a slow reaction with the water producing HF.

The HF and the Antimony Pentafluoride in vapor form react as fluorantimonic acid on the surface Iron Hydroxide yielding our supposed salt and additional water.

The water produced will tend to destroy the acid.

As such I was thinking to start with another Iron salt.

Thanks for your help
