What makes you say it's an illusion? The topic starter's reasoning is sound: if "flesh" can have consciousness, then certainly iron can too. In theory.

I didn't know people still used medieval units. Care to express that in thumbs per teaspoons? :)!

This is typically something you want to evaluate numerically, for instance with Comsol Multiphysics. However, the accuracy of your results would still be limited by estimated values of for material properties like the thermal conductivity.

I hope you're right!

What do you think will be the cause of the civil war, Mr. .. Goethe?

It's been more than 60 years since the last world war. Society has become more globalized than ever. We (the Western world) are living in more luxury than kings were, a century ago*. I honestly can't see us - humanity - live for another half a century without major conflicts. There's just...

What is the reason you can't breath with apparatus when the outside pressure is less than 0.15atm? And would that (hypoxia) be the cause of death in such a situation, or are do other lethal effects take place?

Thanks a lot for that link! Those kind of sites are what I love about the Internet. Unique knowledge being shared for non-commercial reasons. Unfortunately, these kind of pages are more and more hard to find as search machines first list E-bay and all kind of commercially related sites. Back...

Just to clarify, I'm not talking about the threshold of being able to draw too little oxygen. I'll edit the first post. Let's say the person is allowed to use breathing equipment. But no space suit or anything similar that manually retains a high pressure.

...assuming very slow adaptation is possible. How low can one go? And something else: if you're at very low pressure, water or blood would boil at RT (pressure is lower than the vapor pressure of water). Would this mean a relatively innocent cut wound would make you lose a lot of blood? The...

Turning this around, do you think it's possible to leave the bottle opened in the freezer for a while, then opening the freezer and quickly fastening the lid, in a hope to capture the denser, at atm. pressure, -14 degrees Celsius air? Now if one leaves this bottle at RT, the bottle should become...

Thanks guys, that explains it well. One more thing: since the frigde is at lower temperature, is the particle density (N/V) higher than say, in the kitchen? I'm asking because if you look at PV = NRT, and you decrease T but P remains constant, something's got to give..

I have cola-bottle (1.5L) that is half-filled with water. The other half was air, of course. I put it in the fridge (~ -14 C) and after about an hour, before i could see ice formation but when it was very cold nonetheless, i saw that the bottle hull was deformed to the inside, the same way if...

Thanks. From an intuitive point of view, it definitely makes sense. The reason i asked is because my brothers car has a "life fuel consumption" gauge, and it always goes through the roof when in first gear. However, i think that's because in first gear, you go from 800 to 2000 rpm in a...

What about fuel consumption per gear? Basic physics tells me that if the power delivered is roughly equal for each gear (at constant RPM), then fuel consumption should be roughly equal as well. But does it take just as much gas driving 120 km/h with 3000 rpm in the 5th, as it does driving 25...
