Anyone know any problems that are "easy to understand but impossible to solve"? Like Goldbach's conjecture or Fermat's last theorem for instance.

You may have tried this but have you googled "unsolved theorems?"
Also, FLT was solved in 1996.
Haha well that's true, but I didn't mean it literally. I could google up unsolved problems, but I wanted to find some that other people had come across that maybe we could try to think about and try to solve together rather than alone.

ya the unsolved mysteries about aliens and how the american government is trying to keep it from us
I've got 1 but before that u need to give me the best defination of sonic boom.
Haha I don't know what the best definition of a sonic boom is, I think it relates to going faster than the speed of sound and somehow creates a shockwave by displacing air or something fancy lol
Ok now the question is - why doesn't light create sonic booms?? ¿¿
|dw:1437977975618:dw|
light does not make sonic booms, because by definition sonic = sound
Got one: Question: Five pirates are parting ways after finding a treasure of 100 pieces of gold. The pirates decide to split it based on a vote. Each pirate, from oldest to youngest, gets to propose a plan on how to split the gold. If at least 50 percent of the other remaining pirates agree on the plan, that is how they will split the gold. If less than 50 percent of the pirates agree, the pirate who came up with the plan will be thrown overboard. Each pirate is smart, greedy, and wants to throw as many others overboard as possible without reducing the amount of gold they get. What plan can the first (oldest) pirate propose to live and get as much gold as possible?
instead light's version is redshift
I didn't get that @nincompoop
ya don't focus on the redshift LAUGHING OUT LOUD but sonic = sound
oooh good questions @hhopke and @imqwerty and... hahaha you too @Astrophysics :'(
I've got 1 more wait
do not focus on the word use, but instead on the mechanism doppler effect is a characteristic that both sound and light produce. less focus on the word, but more on mechanics and equation
I am looking in my differential equations book since I remember shockwaves came about from solving with the method of characteristics or something.
there are some phenomenon that the english language or other language cannot describe properly
yeah like things that aren't particles or waves... :P
laughing out loud
I think i must learn about redshifts nd ol nd then come here to debate.
qwerty made a uniform spherical magnet. Where are the poles of that magnet located??
use ferromagnetic metal
metal sheet
magnetism ftw
hahaha the poles are on the outside and center?
isn't this what gauss proved?
Prove that u can make an A4 size paper reach mounteverset's top with one end of the paper touching the groung nd the other end at the top. U can tear the paper.
well, tear a piece, leave it on the ground, then take the other piece to the top of the mountain lol.
Well played...
U can't tear the paper nt even a bit
Nd the mounteverset is the real mounteverset nd nt a plastic toy or drawing.
Ik the answer to this one :)
can we use magnetic flux on that sphere magnet pole problem?
U need to prove your answer theoretically
Wait- do they have to be on the ground and at the top at the same time?
Could we use tesseracts? Like from a wrinkle in time?
Ooooh explain that that sounds cool
I was just going to do something like cut the paper like this: |dw:1437979349526:dw|
no cutting nor tearing
ok ok crap
use tangent ratio
Well technically the top of mount everest is the ground at that point... XD
|dw:1437979534544:dw|
|dw:1437979584308:dw|
|dw:1437979492646:dw| Theory of tesseract idea.
what's up with the tessarat?
The concept was bending the universe and everything in it to make the distance between point a and point b shorter.
okay he said we can tear the paper
|dw:1437979662627:dw|
then tear the paper about the size of an atom and then line them up HAHA
hmm can we calculate this? HAHA now I am interested
how many atoms are there in an A4 paper
figure out the dimensions and assume that the paper is made of carbon (primary)
Cool I have thought of a similar concept to this tesseract thing; what if nothing moves but instead space just changes? I guess in a sense this already happens, that's what the metric tensor describes in general relativity. :P
I have to go. Will check back in the morning to see what is eventually figured out. :)
ya I thought of relativity but wouldn't everything stretch including the mountain?
stretch = turn red LAUGHING OUT LOUD
use a miniature mteverest
No u can't use tessaract ol u have is power nd brain power nd the paper use these thinga to get the paper to top
Yeah or we could model it as being made up of cellulose like the sugar monomer length whatever that is
he said "prove" and I say perform an experiment
the paper is an ordinary paper which can be found in your notebooks :)
Also I was looking into this: Cherenkov radiation is the light analog of a sonic boom.
sounds like something I never learned
http://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/cherenkov.html
explain this: is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium
u all will be like ( ͡° ͜ʖ ͡°) after seein the answer
phase velocity of light in the medium
ohhhh nvm
tell us, qwert
be mindful that I might chop you into pieces
Yeah I already have my knife ready tbh
lolol I am imagining qwerty sweating over there haha XD
I am curious about the sphere magnet's poles too because Ive only done flux on spheres with physics |dw:1437980486187:dw|
terrible drawing
ok ( ͡° ͜ʖ ͡°) the thickness of the paper is about 1^(-3) m or even less so when we fold the paper half the thickness doubles ( ͡° ͜ʖ ͡°) now if we keep foldin the paper half nd half nd half about 2^16 times then the thickness of paper will be = 1/(-3) x 2^16 m which is even greater than height of mount everest ( ͡° ͜ʖ ͡°)
|dw:1437980547551:dw|
same concept as cutting into atomic size
i've prepared my swords
So basically we can do it if we ignore certain laws of physics lol
ya
this kid did not even acknowledge our answer that it is the same concept
I got the ears and eyeballs I want to stir fry them
yes!! all u had to do ws- prove ur answer theoriticaly nd ur method should be simple ( ͡° ͜ʖ ͡°)
o ya my method is theoritcally and can be solved
carbon atom's radius is 67 pm
we can assume the volume of the paper
by its volume, we can estimate how many atoms are present
|dw:1437980893036:dw|
so we are assumin that the paper is made of C s so we can take the mass of Na atoms of C = 12gm ??
|dw:1437981064279:dw|
ya use your moles and avogadro's constant
LAUGHING OUT LOUD
mass of a sheet of A4 paper = 4.5gms molar mass=12 moles=4.5/12 no of atoms =2.25 x 10^23 diameter of each atom=134pm so ASSUMING that all atoms are in line so MAXIMUM length of the paper = 2.25 x 10^23 x 134 x 10^-12 =2.25 x 134 x 10^11 m omg yes nin is also correct ( ͡° ͜ʖ ͡°) but u can't calculate this^ thing by volume ( ͡° ͜ʖ ͡°)
I was going to look up density of paper LAUGHING OUT LOUD
lol i ws also goin to do that but then i thought that i wuld have to multiply it with the volume so it wuld be a tedious task so i directly looked up for the mass ( ͡° ͜ʖ ͡°)
We could have dissolved the paper, thereby not tearing
HAHAHA
are there any applications for directrix?
Gathering of the geniuses. Just saying. :)
Lollipop
^the reason why i hate autocorrect.... *LOL
Hahaha
If IF time machine gets invented then what do u think will happen?
Hmmm well when I was a kid I told myself if time travel is real I'll put a key here from m future self, but I never found the key so I guess it won't happen.
So u putted the key so that one day when time machine gets invented u can bring back the key to time when u placed the key there. Right?
Hahaha well no, but that's a good point, where would the key end up and where did it come from?
I think that future time travelling is more likely to happen as compared to goin to past
Yeah I mean we all travelled from yesterday to today so we already do that anyways :P
I mean going to future with respect to other people
Yeah, I guess so. So what made you think about this sonic boom for light?
Well my hobbie is to think so while thinking i thought that y doesn't light makes sonic boom.
Cool :)
