Our knowledge of science and technology has advanced exponentially over the past several hundred years. What advancements do you think we will make in the future?

Arthur C. Clarke once wrote that the technology of any sufficiently advanced culture is indistinguishable from magic. Do you think our understanding of areas such as physics, astronomy and biology will change so much that a modern scientist would be utterly unable to comprehend it all? Will future scientists look back on our understanding of basic concepts like the structure of the atom with some amusement, just as we do now with many scientists of just a few centuries ago?

Or do you think we're getting anywhere near the absolute limit of understanding?

I'm a mystery writer. Would love an explanation in layman's terms. Give me just enough medical jargon to sound like I know what I'm talking about! I like to encourage my readers to do further research on stuff from my books. Thanks to any and all who answer.

Taking for example two different areas biology and astronomy
- Richard Dawkins vs Stephen J Gould
- Stephen Hawking vs Carl Sagan

Which ones do you prefer to read? Of course you can argue they are all good scientists…

Ok so this king puts all his gold into 8 bags such that each bag weighs the same amount. One days he finds out that someone stole some of his gold from a bag but doesn't know which one. How the hell does the poor king figure this thing out?
note: The only scale in the whole universe was the pan balance.
The kings needs to figure this puzzle out in only 2 steps.
that right only 2 steps.

good luck my subjects.

Not as easy as it sounds, because the water may have more complete contact with the skin, but the earth is more conductive of heat.

My son is supposed to do a project for school to make a submarine that will float-sink-float or sink-float-sink. Any suggestions on how to do this and if you could help me explain why it works to him also would be greatly appreciated!

knowing the charge of an electron is -1.6 x 10^(-19) C, how do i find how many electrons pass through a cross section of a wire each second if a current of 1A flows in the wire carried by electrons??


also if the net charge through a cross section of a certain element is given by q(t)=3-3e^(-2t) C, how do i determine the current through the element??

thanks so much for any help

How come the crystallization temperature is determined during cool-down and not as soon as the substance dissolves?

For example, if I'm trying to find the crystallization temperature of salt or sugar, how come I'm supposed to use the temperature at which it crystallizes when cooling down instead of just taking the temperature at which it fully dissolves?

Isn't that the same difference as ice freezing/melting? I'm guessing there's some good reasoning here, but I'm just not quite sure what it is ;-)
