Knowing the initial pH isn't enough to answer the question. You need to know the buffering capacity For example, you could fill the pool with a saturated solution of bicarbonate of soda and the pH would be about 8.3. Adding 0.019 moles of acid would make no measurable difference.

I think democracy has been proved to be mathematically doomed http://en.wikipedia.org/wiki/Arrow's_impossibility_theorem In short, the theorem states that no rank-order voting system can be designed that satisfies these three "fairness" criteria: If every voter prefers alternative X over alternative Y, then the group prefers X over Y. If every voter's preference between X and Y remains unchanged, then the group's preference between X and Y will also remain unchanged (even if voters' preferences between other pairs like X and Z, Y and Z, or Z and W change). There is no "dictator": no single voter possesses the power to always determine the group's preference.

Well, apart from any other problems, we know what causes migraines- it's a glitch in the blood supply in the brain. The higher incidence in women is probably due to hormonal factors (one bit of supporting evidence is that, in children, migraines are more common in boys than in girls). And, on the whole, your post doesn't seem to have anything to do with entropy. And, you can't scan space for a photon because the photon is moving at c.

Just a thought. Doesn't the definition of "spaceplane" rather rule out "air breathing"? In space, no one can hear you complain about the lack of air.

I wonder how many have been reported as the "BIGGEST EVER DINOSAUR".

"Can it encapsulate human emotions and provide a channel for connecting with the Unknown?" Since faith can't do that, the point is moot. "Can't we worship in the open, like some of our pristine ancestors?" Apparently, it's allowed in Christianity "For where two or three are gathered together in my name, there am I in the midst of them." http://biblehub.com/matthew/18-20.htm And it seems fairly common in other faiths too. http://en.wikipedia.org/wiki/Kumbh_Mela http://en.wikipedia.org/wiki/Hajj

That's because the YEC view of creation includes sticking their fingers in their ears and saying "Lah lah lah: I'm not listening" when presented with evidence they don't like. So, when I point out that we can count tree rings going back further the the YEC view says is the age of the Earth, Their reply is to ignore the point, or try to pretend it isn't true. http://en.wikipedia.org/wiki/Dendrochronology

Perhaps I have not made myself clear here. I am talking about sending the beam to the satellite. I'm not talking about the beam that comes back to the people watching television or whatever. They send that signal from a dish. If that dish is not pointing at the satellite then the signal will not reach it. The reason they use geostationary satellites is that they are always in the same "place" in the sky. But if,as you claim, the earth speeds up and slows down then the dish will not point at the satellite any more. It will miss by about a hundred miles. Once I have told you that the beam will miss by a hundred miles, what calculation do you need to do to understand that the beam will miss by a hundred miles? People would notice if the beam missed the satellite by a hundred miles because the system wouldn't work. It works, so the beam must continue to point at the satellite. But you say that the dish should move faster on some days than others. If it did that they would need to realign the dish. They don't. So, you are wrong. And you still don't seem to have answered the questions about the people who measure the Earth's rotation. Why don't they see this effect you claim? Do you understand that if the facts don't agree with your ideas then you should change your ideas? Reality does not make mistakes.

For the record, a turbomolecular pump is not the same as a rotary vane pump. http://en.wikipedia.org/wiki/Turbomolecular_pump http://en.wikipedia.org/wiki/Rotary_vane_pump However I suggest that the OP talks to the people who design and sell pumps. They have lots of experience with that sort of question.

And the point I made was that the direction of the dish is such that it misses the satellite by a hundred miles. Seriously, do you think it matters if you specify the angle by which it misses or the distance by which it misses? The problem you have is to explain why that effect has never been noticed. Can you do that?

What do you have so far?

There are essentially two types of bonds that hold hair together- the amide bonds between the amino acids and the disulphide bonds that cross link between the chains of amino acids. Thioglycolate destroys the disulphide bonds and hydroxides attack the amide bonds. Together they will dissolve all the things that give hair its structure. Incidentally, I'd be worried if anyone was using much hydroxide anywhere near my skin, it's very corrosive.

Not all cells need oxygen. Some find it toxic.

"Yes they do all have side effect but if a drug has side effects of something as serious suicide or depression should we allow it to be prescribed to teenagers and children?" Still yes. You seem to have forgotten that the people who do the prescription are well aware of the balance between side effects and benefits. You wouldn't prescribe such a medication for a cold, but you might do so for an inoperable cancer. All drugs include death as a potential side effect, so your view would seem to exclude prescription of any drug- on the basis that it might kill the patient. You are not looking at the other side of the equation and by doing so you are not seeing the whole picture.

IIRC one of them is defined by the definition of the amp. The other is experimentally measured (Or, it was until they redefined time in terms of the speed of light.). However, that's still a reasonable explanation. The speed of waves traveling along a spring depends on the tension and the mass per unit length of the string. In a vaguely similar way, the speed of em waves travelling through a medium depends on ε and μ. I don't need to explain why the string has a particular tension and lineal density to say why the wave velocity is the value it is. I can just say it's sqrt (t.(m/l))

It works for me . Here's the abstract: searching for it might get you to a copy of the paper Abstract: This paper will begin with a short review of the Alcubierre warp drive metric and describes how the phenomenon might work based on the original paper. The canonical form of the metric was developed and published in [6] which provided key insight into the field potential and boost for the field which remedied a critical paradox in the original Alcubierre concept of operations. A modified concept of operations based on the canonical form of the metric that remedies the paradox is presented and discussed. The idea of a warp drive in higher dimensional space-time (manifold) will then be briefly considered by comparing the null-like geodesics of the Alcubierre metric to the Chung-Freese metric to illustrate the mathematical role of hyperspace coordinates. The net effect of using a warp drive “technology” coupled with conventional propulsion systems on an exploration mission will be discussed using the nomenclature of early mission planning. Finally, an overview of the warp field interferometer test bed being implemented in the Advanced Propulsion Physics Laboratory: Eagleworks (APPL:E) at the Johnson Space Center will be detailed. While warp field mechanics has not had a “Chicago Pile” moment, the tools necessary to detect a modest instance of the phenomenon are near at hand.

"Should drugs which cause people to become suicidal be allowed to be prescribed to teen or Children?" Yes.

Do you really not understand that those are the same thing? If I point the dish in the wrong direction by some angle, it will miss the satellite by some distance. You can calculate one from the other.

I'd be hard pressed to detect a change in length of say 1% by just looking. Any change smaller than that and I'd almost certainly miss it. According to this page http://en.wikipedia.org/wiki/Length_contraction I would need to get an object to about 42 million metres per second to get the length to change by 1%. The fastest that any macroscopic (i.e. visible) object has ever been accelerated to is rather less than that. 16,000 metres per second (and the projectile was tiny) http://www.colorado.edu/physics/phys2020/phys2020_fa07/LectureNotes/nagle_phys2020_fa07_lecture26.pdf So, the simple answer is no, length contraction can't be seen with the naked eye. On the other hand, nor can a virus, but that doesn't stop me getting colds.

Perhaps we should set up a topic in the religion section of this site for people to read before they post anything. It could include things like " God isn't omniscient (or omnipotent) because it's logically impossible. Does He know the question to which he doesn't know that answer? If He knows it then he knows he doesn't know everything. On the other hand, if he doesn't know it then he doesn't know everything. Similarly, can H set himself a task He can't accomplish? If he can't set it, He's not omnipotent. If he can't' achieve it then He's not omnipotent. That would get round the problem of people who base their "argument" on grounds that are known to be logically impossible.

sugar or salt.

Why do you think I'm just messing about? Is it so that you can write of criticism of your assertions as "just a joke"?

Might it be better to pray for the absence of bullies? If you get rid of one potential group of victims they will find someone else to bully anyway. So it seems that the problem is those who disrespect others, rather than those who are not respected.

In many jurisdictions, death is defined as the lack of brain activity so, according to the OP you don't die until 7 minutes after you die. That's clearly nonsense. Ophiolite has also pointed out that it makes no sense.
