How are pictures drawn by M.C. Escher breaking the laws of physics?

In summary, the drawings appear to be violating the laws of physics. Which laws and equations are they violating? Is this a homework problem? If so, I can move the thread to the appropriate homework forum.

Why are the drawings http://britton.disted.camosun.bc.ca/escher/ascending_and_descending.jpg" [Broken]breaking the laws of physics? Which laws and equations are they violating?

Also, what is your thinking so far on this? What laws would be the most ovbious for starters?

yeah, its a homework problem. i really have no idea because i pretty much don't really know any laws...

Sure you do! Physics is just the study of nature. You intuitively know laws like objects that have more mass are harder to push, you just don't know the equations for them yet. What grade are you in right now? Is it possible for someone to be standing upright one side of a flight of stairs and have another standing upright on the other side of the flight of stairs? Why?

lol I am in 11th grade 7 honors physics! I know that its not possible but I don't know why. I can't just say gravity lol but that's the only thing I can think of.

Ok, let's think about it this way. What provides the gravity that holds you down on a flight of stairs? The Earth or the stairs?

What can you say about Waterfall and the conservation of energy?

That's a really good one, chroot.

Well I am thinking its both considering everything with mass has gravity. But ofcourse the Earth has a lot more mass. I didnt even look at the picture that way. I guess I get the point but I don't know what law that would pertain to or how to put it into the words. The best I can come up with is that the picture is wrong because the thing with the bigger mass, the earth, has more pull than the stairs do on the people so all of the people should follow that in how they are walking on the stairs but some of them don't...

we just took a test on that today (one i failed btw but none the less...) you can't destroy or create energy but I don't see how that has to do with the waterfall being all weird and not making sense how it falls...

If the waterfall flows forever, turning the waterwheel all the time, and has no external source of energy, what can you say about energy?

Surely, people inside the building could be using the waterwheel to run machines, mill flour, or do any other kind of work they wished to do...

try this, or if you can't try this, at least think about it. Take two bottles, fill one, and connect them with a hose. If you tip them both upside down so that they are side by side and the hose is hanging below, how far do you have to lower the empty bottle before water starts transfering to the empty bottle? I can tell you right now that you can't get the water to go up higher than it started. Why? hint: Potential energy/conservation of energy. Do you have a textbook that you could review from?

i don't have a book but i know what ur saying dontdisturbmycircles i guess.

and chroot. I sort of understand, but like... so the energy from the water is being transferred into wheel... to turn but the wheel is pushing the water too. But I guess a lot of the energy from the water turning the wheel also goes a lot to turning other gears and stuffs

I still have no clue about the other ones

At the top of the waterfall, the water has a certain amount of energy. Namely, it's potential energy, given by

[tex]E_{p}=mgh[/tex]

Where [tex]E_{p}[/tex]=potential energy
m=mass
g=gravitational acceleration, ~[tex]-9.81m/s^{2}[/tex] on Earth's surface,
and h = the height above the surface, or above the "reference point".

So what happens when the water falls onto the wheel? Where does the water's energy go? Does the water do WORK on the wheel? How much energy would it take to raise the water back to it's original height? Do you see the problem? :smile:

Hint:conservation of energy! In order to raise an apple above a table so that it can exert 10N of force on the table when it falls, you must use 10N of energy raising the apple to that point if you pick it up from the table.

If you don't have a textbook, what exactly have you gone over in class? review your notes, I mean, you had to have learned something that you can apply here.

If the waterwheel spins forever, without any external source of energy, then it's "creating" energy all the time -- which is a violation of the conservation of energy.

yeah now i do see the problem with that one

how does belvedere ?
 

1. How is it possible for Escher's drawings to defy gravity?

Escher's drawings often depict impossible structures that seem to defy the laws of gravity. However, this is achieved through the use of optical illusions and mathematical principles. By manipulating perspective and creating paradoxical shapes, Escher creates the illusion of gravity-defying structures.

2. How do Escher's drawings break the rules of geometry?

Escher's drawings often feature impossible shapes and structures that seem to go against the rules of traditional geometry. However, he was able to achieve this through his understanding of mathematical principles, such as tessellations and the concept of infinity.

3. Are Escher's drawings physically possible?

While Escher's drawings may seem physically impossible, they are still based on mathematical and scientific principles. The structures he creates may not be possible to build in the real world, but they are still based on logical and consistent mathematical concepts.

4. How does Escher's use of perspective contribute to breaking the laws of physics?

Escher's use of perspective is a key element in creating his mind-bending drawings. By manipulating the viewer's perception of depth and space, he is able to create impossible structures that seem to break the laws of physics. This is achieved through precise and calculated use of perspective and optical illusions.

5. Can Escher's drawings be explained by science?

Yes, while Escher's drawings may seem fantastical and impossible, they are actually based on scientific principles. By combining his artistic skills with his knowledge of mathematics and science, Escher was able to create intricate and mind-bending images that challenge our understanding of the physical world.
