@vil: Well, it's actually Bell herself that has a similar opinion:

It has been suggested that I should have had a part in the Nobel Prize awarded to Tony Hewish for the discovery of pulsars. There are several comments that I would like to make on this: First, demarcation disputes between supervisor and student are always difficult, probably impossible to resolve. Secondly, it is the supervisor who has the final responsibility for the success or failure of the project. We hear of cases where a supervisor blames his student for a failure, but we know that it is largely the fault of the supervisor. It seems only fair to me that he should benefit from the successes, too. Thirdly, I believe it would demean Nobel Prizes if they were awarded to research students, except in very exceptional cases, and I do not believe this is one of them. Finally, I am not myself upset about it – after all, I am in good company, am I not!

When the paper was published the press descended, and when they discovered a woman was involved they descended even faster. I had my photograph taken standing on a bank, sitting on a bank, standing on a bank examining bogus records, sitting on a bank examining bogus records: one of them even had me running down the bank waving my arms in the air. Look happy dear, you've just made a Discovery! (Archimedes doesn't know what he missed!) Meanwhile the journalists were asking relevant questions like was I taller than or not quite as tall as Princess Margaret (we have quaint units of measurement in Britain) and how many boyfriends did I have at a time?

1) no, trading is not capitalism.
2) kids in China did not - that is borderline silly. Creating and marketing the iphone created a DEMAND, the MARKET had been in place already (the US constitution, the fed, the dollar, cellular infrastructure, people free to buy things of their own will, the internet et cetera et cetera et cetera ad nauseam - takes a lot of preconceptions to be able to sell such a product)
3) basically yes.
4) I am sure we agree on a lot of things, this is one.
5) I understand government=socialism. The government of the US of A funds a lot of things that would be hard to justify as socialism. Maybe an argument can be made that basic research is a social investment IDK.

Basic research does not equal fast progress though. You can be as clever as Archimedes or Leonardo but steam trains require capitalism to make sense. Iphones required masses of rich crazy americans to take off - a market and demand. Without a market and demand (or a war) progress is slow as f***.

When someone says something like "we're exploiting parallel universes", what they mean is that one of the many theories that can be used to describe quantum behaviour such as entanglement is to do with parallel universes.

That doesn't mean there aren't other theories, it doesn't mean there are parallel universes, it's just one of the few ways we can make it make sense is if it exists and carries information in a dimension that is not tangible to us.

When Archimedes invented his screw, using gravity to drive water uphill, he could have said that he's using an invisible multi-dimensional goblin to move the water; well that's one theory and its irrefutable until Newton makes an appearance. And even then you can still say "yeah but what we know of gravity is still a multidimensional goblin."

Having said that, it has as much likelihood of being correct as any other theory in its infancy.

He went full extension...you never go full extension! I suspect the designers never intended for the camera to ever be beyond arms length. At full extension with that large a camera the pressure on all the components was too great.

Like Archimedes said "Give me a place to stand and a long enough lever ... oops!"

In the opening question she blew it. What if the rock is lava rock, which is LIGHTER than water? That means you can't figure out the answer without knowing the density of the rock.
Archimedes equation is only useful in figuring out weight for things that are buoyant. Anything more dense than water (or whatever medium you're in) will only displace it's own volume in water, not it's mass.
That's why I think the wood block should weigh more in a vacuum. It displaced more air, so was more buoyant, and so had more buoyancy to lose. It seems to me she set it up poorly again, because if they weigh the same in air, but are different densities, they would seem to need to have different masses to achieve balance, but she said they have the same mass, but I think she should have said 'they weigh the same'....just as @Barbar and @Stormsinger indicated above.

Problem 1: The scale will tilt towards the lead block. It's the same principle as Archimedes, except using air instead of water. When there is air, there is a buoyant force exerted on any object immersed in it. Remove the air, and the weight of the object goes up, by the weight of the same volume of air.

Problem 2: 20*pi meters. I'm not sure how extreme physics is involved in this one at all. It's trivially derived from the definition of circumference.

Unfortunately the process of discovery didn't exactly lend itself to a dramatic announcement. One imagines Archimedes lowering himself into the bath over several months waiting for a statistically significant volume of water to be displaced.

I imagine that pretty much everybody knew he was going to be getting a Nobel Prize at this point as well.

i actually imediately thought of sticking my head in a bucket full of water and collecting and weighing the water that spilled over.
Thank you Archimedes


I as well knew the answer right off, but I should: I love my Physics so I should also know at least when to use the easiest of some uses...

Yes, there are a few different ways mathematically AND experimentally (although they all deal with displacement) to carry this one out. It's really quite a good one to use one day on a High School physics class if you're a teacher and going through that section.

Believe it or not as long as your chest and knees are on the ground, with your neckline not over the scale and your jawline just a few inches over it then the point of your chin onto the scale it will still get a very close result. This is playing around with the fulcrum of your "head's" weight.

For all I know if you could get a control room that provided an electrical field that penetrated the entire human body you could develop a technique to do it that way as well. By control I mean a structured room that absolutely cancels out all of the electrical field in it when the room is empty or at its controlled state; so the only time that the electrical field appears is when something foreign enters into it. Call it resistance weight measurement or something.

You dont collect the displaced water, you just measure the weight of the bucket before and after, split the difference!!
Far easier than trying to scoop up spilt water


you got me there lol
