One would assume that these aren't going to have passengers or crew. If it blows up at altitude, the whole balloon should combust, producing harmless water. I am sure with modern safety precautions even the recovery could be automated to ensure that no human life is even endangered. Even the Hindenburg wasn't that great in terms of actual loss of life.

Actually I do believe that Walmart are trying to overcharge people for the products they get and I don't think most people would disagree. The main point of my post was that their offer of matching prices encourages people to shop there as it implies that their prices are competitive.

Well UK perspective ;)

I think the real problem here is that Walmart are trying to overprice people and then console them with the offer that if they can bring in a cheaper price they will honor it. The real solution would be Walmart not overpricing, but clearly they are not prepared to do that so they offer these deals.

These deals trick consumers into thinking that they will obviously get the best deal there as why else would the shop offer this deal. The cashier does not necessarily know how much these items are worth and it is clearly not their fault. It is a large company trying to extort as much money as possible from the people who do not bother. If they are not willing to put in price checks with other shops and keep wanting to overcharge normal customers, then this is the way they must do business.

Fallacy fallacy

I agree generally with the above. For some background lectures, I would suggest Leonard Susskind's lectures. A highly entertaining lecturer and knows his stuff. But again, the above is true in that the only way to truly understand physics is to do some problems. To combine it with IT, you can try doing simulations of things. Alternatively try your hand at some masters level projects. (eg. these)

And then only 20 years since his ./ comment!

Never before have I so wished I had mod points to give to an AC.

I don't think you owe taxes to any country unless you are a US citizen abroad and then you owe taxes to the US. See this

Yep. Should a player who wins one game with straight flush be immediately declared a poker champion? I don't know, he's stopped playing.

Alternatively, if they were 1c more expensive, these transactions just wouldn't happen. More businesses would incorporate overseas and the same behavior would continue without the US getting any revenue.

Pretty sure that would be Irish revenue but you would have to pay customs taxes for the package.

Yes, because Ireland is only a holding place for money that should be paid to the US and not part of Europe at all

It is better that ten guilty persons escape than that one innocent suffer
