So is the reason those at the top of society turn to religion because they cannot get satisfaction from their lives because they don't work, and the reason those at the bottom can't get satisfaction is they can't work in the way which would give them satisfaction because of the way society is...

Can someone clarify whether this is right and add any other important/useful information about this subject please: Marx believed that religion exists because people cannot understand society and people therefore turn to religion because they are suffering either physically or intellectually...

Was mercury used as a preservative in vaccines, and if so, in what doses, and is there any evidence that this caused increased numbers of neurological/psychiatric disorders?

Why is the air colder in the upper atmosphere?

Thanks, I understand it better now.

Gravity keeps you stuck to the floor, friction reduces your acceleration. Gravity would still happen, even if the Earth was not moving in relation to the sun. Is that what you were asking, I'm not quite clear? You are moving relative to the earth. What if there were 6 skiers on the planet...

Kierkegaard said faith is "the acceptance of objective uncertainty" I have 2 questions about Kierkegaard: 1.Kierkegaard said faith is "the acceptance of objective uncertainty", his point being that we cannot be certain about the validity of our beliefs, and there will always be a 'leap of...

I can see what you're saying, but I thought that the additional amount of energy lost as heat via friction in the faster-moving 'single' system would be less than the amount of energy lost through friction in two systems, if you were doing the same work with them both running at a lower speed...

But if they can use the freezers to cool the supermarket, yes, they would have to work harder, but they wouldn't need any air conditioning systems in that area, so it may well be more efficient, as there would be fewer moving parts etc.

Perhaps it was badly phrased. I just wanted to ask what the researchers' aims for this research were, which I assumed were to confirm our theories.

I came across this article today. http://http://www.dailymail.co.uk/news/article-1193070/Shoppers-cars-soon-able-power-supermarkets.html" Does the energy they get from the cars come from the car losing gravitational potential energy, in which case the cars will have to expend more energy to...

Laughing is primarily a social tool, and is only really used by humans, as our social communications are more subtle than most other animals'.

I thought that the subducted crust simply becomes part of the mantle- the mantle is, after all, very hot rock, magma. I didn't think there was a debate about it. But what can they learn from this? That plate tectonics is correct? What more is there to learn?

Even when a patient is put 'on oxygen', the gas they are breathing is not pure oxygen, it just has a higher % in it. The lungs are generally very efficient at getting oxygen out of the air and into the blood;I heard that the red blood cells leaving the lungs are about 98% saturated with it, so...
