Interesting. The article says "Lower courts have thus far ruled the Glomar response to have potential merit if the secretive nature of the material truly requires it, and only if the agency provides "as much information as possible" to justify its claim". Well, it's no secret that: the US has nukes and The admiral will obey orders.* so, why bother to deny the fact that, if ordered to, he will launch nukes? That's what they are for. * OK, if the admiral thinks the president has "flipped" that gets tricky- however it's still reasonable to assume that the admiral will usually obey orders

There's another reason for using a ribbon, rather than a rod- lower self-inductance. You would think a big thick lump of metal would look like a practically zero resistance load, but the rate of change of current for a thunderstorm is huge and even a tiny inductance creates a significant voltage drop. Not sure, but I think the magnetic properties of steel would increase the inductance even more than the resistance.

Because, when it comes down to it, they have more faith in science than in God. There are few things more widely regarded as " an act of God" than a thunderbolt, but they can't trust their God to protect the building from Himself. (The usual excuse is "it's a condition of the buildings insurance"- but why would no insurance company grant them an exception if the evidence didn't show that God destroys churches roughly as often as other buildings?)

Today I learned that the man in that video thinks that H2O2 is "2 parts hydrogen and 1 part oxygen" (about 1 min 10sec.) He thinks it's use by the body is a recent discovery Well, this wasn't new 30 years back when I was a student. https://en.wikipedia.org/wiki/Respiratory_burst I always thought the main use of it in cleaning wounds was that thebubbles would lift the dirt out. It simply doesn't last long enough in the body to do much harm (except in the rather weird situation of causing an embolism)

The US has nukes. If the senior staff of Armed Forces are not prepared to say, publicly, that they would use them, what are those nukes for? What else should he have said? Frankly, it's a stupid question; there's only one answer. Who asked it, and why?

It would have been better if he had said " I'm not answering that". It would be better yet if it didn't matter that he answered it. The problem's Trump, not Swift.

A lightning strike will deliver something like 10,000 amps or more (the record is 20 times that) The power dissipated in a resistor is IR2 so the power is 100 million times the resistance. You really want to keep the resistance as low as possible. Ten ohms means that it's dissipating a gigawatt. (and the record breaking bolt would mean 400 GW A hundred microseconds at that power is 100 KJ (or 40 MJ if you are unlucky) Here's one way to put that in context. https://en.wikipedia.org/wiki/Muzzle_energy

My opinion is that only her opinion counts, and I think the law agrees with me.

Power dissipation in a conductor is proportional to resistance and I think the resistance of rebar is a lot higher than that of the copper strip they use for lightning conductors round here. So using rebar might be better than nothing, but it might get turned into shards of red hot metal (Of course, with a big enough strike, that might happen to copper too). A lightning condctor on a building doesn't mean the building is more liekly to get hit- it means the conductor is more likely to get hit. Who cares? That's what it's for. On a vaguely related note, why do churches have lightning conductors

None of us is the woman to whom the picture + video were sent. Therefor none of us is in a position to say it it constitutes "harassment".

Has anyone ever assembled an ikea product? Seriously, without assumptions about what words (or pictures or symbols) mean, you can't put any idea across. So you can't really deduce anything, because there's nothing on which to base any deduction.

If you drop electronic gear into water the best thing to do (after wiping the surface dry) is to remove the battery in order to avoid electrolytic corrosion. So the state of the (relatively cheap) battery shouldn't matter much.

I could use a laugh. If you don't think it's falling, then something must be keeping it from doing so. What do you think is holding it up? Skyhooks?

OP = Original Post(er) That's you, in this thread. OK "What can be deduced without making presumptions!" Nothing. That's not a philosophy that will get you very far, but the idea of there being no recognised meaning for words is the inspriration for this. https://xkcd.com/1860/

"What can be deduced without making presumptions!" The traditional answer is "I think therefore I am". Another possibility is that I can deduce that the OP doesn't know the difference between ? and !

Interesting, but when the language evolved, the area was pretty much as religious as anywhere else. The 3 words have similar meanings in English, and the distinction's not always obvious.

"I wasn't talking UHV though" AARgh! It's another person who seems to think that the depth of the vacuum matters to whether or not something going to burst. The air in the bug is at about 760 mm Hg. With the crappy vacuum you get with a water jet pump- say 30 mm Hg the pressure difference between the inside and the outside is 730mm If you use a UHV system the pressure difference is 759.999 mmHg Unless the bug skin's failure pressure differential happens to be between 730 and 759.999 the fate of the bug is going to be the same whichever pump you use. Every now and then people get injured because they hook a normal flask or beaker to a water jet pump thinking "it's not a very good vacuum- so it won't implode". It's not the vacuum that does the work, it's the atmosphere outside - and that's just the same no matter what pump you use.

One word of warning, if the phone is, or contains, sealed areas then putting it in a vacuum chamber might be a very bad idea.

It depends how good the vacuum is. Not much is the simple answer. However if you use a vacuum desiccator, the desiccant picks up all the water and so the water continues to boil off until the temperature falls too far. Then the rate of evaporation is limited by heat transfer. But it's still quicker than an ordinary desiccator (using the same drying agent). One word of warning, if the phone is, or contains, sealed areas then putting it in a vacuum chamber might be a very bad idea.

OK, So I started reading through it, looking for something that actually says anything, and I found this "But from the premise of science, relativity and the idiocy of Einstein, we certainly apply the fact that as Tesla himself face-palmed back in his day that space has no properties. ". Losing the silly bits gives us "But from the premise of science + relativity, we certainly apply the fact that space has no properties. ". Yet space is known to have properties like a permeability and a permitivity. So, the first "meaningful" thing in the OP is factually wrong.

"Well, you just say what I say is "plain wrong" but you don't say, why that what I say is wrong?" Again, plain wrong. Because I did say what was wrong, and why. The bit I quoted before describing it as plain wrong is plain wrong. And, as I said "You just don't let it change (meaningfully) in the first place." If you don't let the pH change then you don't have to change it back, do you? "Can you name a source where it is written that people die f.e. on arthrosis because they followed a alkaline vegan diet?" No, but nobody said they did. Where did you get that daft idea from? "If everything in the body is interrelated, that you seem now not deny anymore, than lungs and kidneys cannot control the pH of blood." I never denied that the whole lot is interconnected. I'm the one who pointed it out.. It is precisely because they are connected that they can control blood pH.

Bit like this one from years ago. https://en.wikipedia.org/wiki/Sokal_affair Be careful what you read

They didn't make a habit of it; they usually only did it once. Today I learned that it was international bad joke day.

What's the bin made from? If it's metal then the sale will corrode it to hell and gone. If it's plastic then salt (or washing soda) should work.
