Back in the 19th century British explorers came across Eskimos who were so isolated that they'd forgotten that any other humans existed. Nevertheless they had a little bit of iron that they used to put an edge on their knives. They had no trade so where did they get it? Fortunately their...

I don't have any solution

A pump’s power is a product of its pressure rise times volume flow rate. Commonly, a pump is specified by giving the pressure rise, or head, it can provide and the flow rate, such as in gallons per minute(GPM). But some pumps provide the user with a chart that shows how the pressure rise can...

So in a setting with interstellar travel I was thinking about interstellar trade. I know the method of travel dicates what is traded, so I will elaborate below: Constant Acceleration: Refueling is virtually not a concern. Stargates: Ships can accelerate for months to reach just bellow...

Lets suppose that in SF universe, due to hyperspace, travel between stars don't require planet killer energies. A mothership can transport kilotons of goods with energy of a few Tsar bombs, travel takes months. What could be valuable enough to transport between star systems? Are there solar...

$\newcommand{\un}[1]{\,\text{#1}}$ https://www.youtube.com/watch?v=xSVHWiZu8NM One of my relatives sent me a link to a video (above) claiming that the WTC towers must have had internal demolition in order to fall as fast as they did. I think there are good reasons to oppose the theory, but I...

This is not strictly a physics question, I just figured this is the best place to ask it. I think everyone is familiar with the subtle difference in the effects of gravity from the poles to the equator. At or near the equator, objects weigh about 0.5% less than they do at or near the poles. My...

Two questions for you lovely and helpful forum members: 1. I have two clocks far from a massive object, relative to which I am at rest, and I let go of one of the clocks. I let it free-fall for 186,000 miles, and then I observe both clocks. Is the falling clock observed to be one second behind...

The trade balance between EU and China is -156.3€ billions, yet today EU agreed with China (http://uk.reuters.com/article/2012/09/20/uk-eu-china-summit-idUKBRE88J0QR20120920) to avoid trade protectionist measures. They keep doing this because China keeps buying EU countries' bonds and has many...

I'm interested in finding a database that contains the bilateral trade (imports/exports) between every pair of countries. I've done some googling and I can't find it all contained in one place. Preferably if it was in a downloadable csv file (which would basically be a godsend for me) but...

The more people with whom you trade the richer you get, regardless of whether they are across the street or across the world; the fewer with whom you trade the poorer you get. If you could not trade with anyone you would have to make everything yourself and you'd be very poor or dead.

Hi all So-called "free trade" is one of the holy grails of capitalism, is it not? And the USA takes the lead in creating and defending free markets? How, then, does one explain this? Just one example of 'capitalist freedom':rolleyes: This is just the tip of the iceberg, of course - if...

Has anyone read "from free trade to forced trade" by Peter Urmetzer? I just finished reading it. It was a bit of an eye opener - it describes free trade as a neutral activity - not good or bad. Great book
