  • From: Jonathon Whitle

    Here is a paradox for you,
    possibly not the sort of thing you're after, in the sense that it is 
    a) all maths, nothing physical
    b) very easy to resolve 
    but here it is anyway...
    
    x=1        multipy both sides by -1
    -x=-1      add x^2 (x squared) to both sides
    x^2-x=x^2-1  factorise
    x(x-1)=(x-1)(x+1)    simplify
    x=x+1              but x=1 so
    1=2  (!!!)
    
    
    
    ANSWER:
    at first glance it may seem baffling, but closer inspection reveals all
    the manipulation is just in aid of hiding the fact that in one of the
    steps both sides are divided by zero, this is of course the hole on the
    proof.
    0*1=0*2 does not imply 1=2
    
    Like I said it's kind of basic, I thought you might be interested.

     I was wondering about something. I assume you are familiar with 
    transformation matrices, in particular those dealing with rotation. I 
    have rotation matrices which rotate 3D objects in 3D space. I don't 
    suppose you have rotation matrices to rotate 4D objects in 4D space (or 
    formulae - one or the other). It would be a great help to the project I 
    am currently working on.
    
    Another letter from Chris:
    I am a young naive student who is very interested in the fourth 
    geometric dimension (ie. not space/time). You mentioned that an accepted 
    statement is thus:
    
    "Fourth Dimensional beings could not fit in the third dimension, as we 
    could not fit in the second dimension, and thusly
    cannot visit it. Upon observation of our dimension, thses fourth 
    dimensional bodies would consider it extremely simple. Just
    like the second dimension is simple to us."
    
    Surely this is not entirely accurate. If you imagine a 3D being (let's 
    say a sphere - a living sphere!) and a 2D being (a square - a living 
    square). Now, if this 2D being was just walking along one day in its 2D 
    space, and suddenly this sphere came down from above and intersected 
    with the 2D being line of sight, would this not make the sphere visible 
    to the 2D being. Naturally, the 2D being can only see the 2D cross 
    section of the sphere (since it would only have 1D (pseudo-2D) vision), 
    and as the sphere descended down and through its line of site, the 2d 
    creature would see its cross section - a line which starts of small (the 
    bottom of the sphere) and begins to grow as the middle of the sphere 
    intersects, then begins to shrink again as the top begins to intersect.
    
    Put in short, the 2-D creature sees 2 out of 3 dimensions that the 3D 
    creature possesses. Now similarly, if a 4D creature visited us, then 
    whatever parts of it intersect with out 2D (pseudo-3D) vision, we would 
    see. Thus, we would see 3 out of 4 of its dimensions. Now if the 4D 
    being we to turn around in our field-of-view, we would simply see those 
    parts which intersected 3D space. It would look like bits of him/her/it 
    phased in and out of [our] existence.
    
    Just a thought. I will send more of my points-of-view as I dive deeper 
    into your site. I love it!!!
    
    


  • From: Tim Poston

    Every mathematiina needs an answer at parties
    to "What is the 4th dimennsion?"
    
    My short one is "I will point along it for you,
    on one condition.  You must point along the first."
    
    `The' 4th dimension no more exists than `the' first --
    they don't come numbered.
    
    
    If there's more time, and/or the person is someone I'd
    like to know better, I explain about waist measurement.
    
    Take the people at a big family reunion, young and old,
    all mixed.  For each person you can collect their age
    and their height; if you mark each of them as a dot on paper,
    far from the left side in proportion to their age,
    and far from the bottom in proporition to their height,
    you get a cloud of points looking something like
    
    
                         *  *    *  *      *        *
                      * *   *   *  *   *          *
                    *  *   *  * *  *  *    *
                 *  *    *    *      *          *     *
                 * *  *     *     *
             *  *  *    *
           *  *  * *  *
           *    *
         *  * *
          *   *
        *   *   
    
    (if you read this in a display with proportional spacing,
    my ASCII sketch will be badly messed up.)
    
    The cloud roughly levels off -- people get to a certain height
    and then stop growing (even shrink a little bit).
    
    Now add a third datum, weight (including reunion food,
    and clothes unless your family is more fun than mine).
    Just as people can have the same age and different heights,
    or the same height and different ages, they can have
    the same age and height and different weights, so this
    is a distinct dimesnion.  The figure goes 3D; I can't do
    good stereo in ASCII, so you'll have to imagine point
    cloud.  (Unlike height, weight does go on increasing 
    with age.)
    
    Nothing very mystical so far.
    
    Now go around and measure people's waists.
    Two people can have the same age, height and weight
    but still have different waist sizes; so the data
    cloud becomes 4D, with thickness in this direction also.
    
    In this story, `the' 4th dimension is waist measurement.
    `The' first dimension is here time, the dimension along
    which we measure age.  If you agree that Age belongs
    along the first axis in my 2D figure, you agree that
    time is the first dimension.
    
    Nu?

    PS, one could add to the limericks on the Klein bottle page
    the quatrain
    
      Three jolly sailors from Bladon-on-Tyne
      Went to sea in a bottle by Klein:
      Since all the sea was inside the hull
      They found the voyage exceedingly dull.
    
    Particularly in comparison to Bladon Races.

  • From: Darlene

    I am just recently getting into the whole theory of the fourth dimension but
    what i have began to think is that the fourth dimension revolves around a
    time line just like our 3d and 2d's do.  We are to be concidered traveling in
    a line in time.  We begin at one point, which no one knows when it is because
    we dont know how we were created, was it god? was it the big bang, but then
    what created the big bang? where does it all start?  Anyways our time begins
    at an open interval on a graph and is continuous to an end.  The end too may
    be an open interval because we can not say what happens after "death."  IN
    the fourth dimension there is no "order" of time.  It is all just scattered
    all over the place.  BUT!  how do i know if i have jumped ahead of time, or
    behind in time?  do we age in 4d? if so then we HAVE to be following a time
    line, its just that in the fourth dimension we do not have to obey the RULES
    of the time line.  Everything is planned out, pre-destined, so in 4d we can
    see what is going to happen and what has happened, yet we have no control
    over it.  This is all beginning to make me think that our 3d is actually more
    of an enigma than 4d.  In 3d we dont know what will happen, but why not?  we
    just dont have the right "tools" to, in the fourth dimension everything
    becomes more set and we can run more freely in time but what is the point?
     we already know what is going to happen, in 4d we cant die, what happens to
    us?  is this "eternity" thing what 4d is about. 
    thank you

    Matter.
     It just moves
    There is nothing else but motion of matter.
    No motion takes place while time is running.
    No one ever has seen time running
    Is it right to conclude that when things are moving 
    there is something like time running beside their motion?
    Something that allows motion? Motion is a result of force.
    what happens when things move is that particles change their distances
    to each other. „How fast?" asks for changes in distances compared to 
    your measure motion: 
    the watch. 
    Velocity is explained without the slightest touch of time
    What is regarded as being a result
    of time is pure motion.
    The concept of time as a dimension to explain
    what happens is superfluous
    Whereas motion needs no time  
    quite the contrary time is not thinkable without
    moving particles when we „detect" time with watches  
    we compare motions
    motion can be thought and explained without
    a thing called time.
    

  • From: Timothy Jenson

    I've been sitting here browsing your web pages for about 3 hours and my
    mind is racing.  It's been a couple years since I've been able to sit back
    and theorize about dimensions, time, space, etc.  I really like the
    theories presented in your pages, as they represent basically the exact
    ideas that I have come up with for the same topics.
    I'm not sure if you are a spiritual person or not, or if you have ever read
    or heard about the Kabala, but I believe it may be of great interest to
    you.  Without understanding of the concepts of higher dimensions,
    energy/matter relationships, etc., the religious ideas in the Kabala don't
    seem to make very much sense, but I've found that if I relate the ideas
    found there with scientific ideas such as those in your web pages, the dots
    seem to connect themselves.
    I can't remember offhand where I got the file, but a while ago I downloaded
    a file called Notes On Kabala (NOK.ZIP).  I had read a few books on the
    subject before getting this file and was very intrigued, but the way the
    text in that file is presented, it becomes very easy for someone with
    scientific knowledge to understand how the concepts of the Kabala are more
    than just spiritual beliefs, but a guide to understanding the fundamental
    nature of everything.
    I'm don't know how busy of a person you are, but if, sometime, you are in a
    'deep' thought mode and interested, I really suggest you try to find that
    file.  I am very sure you will be able to use the information to form new
    ideas, which I someday hope to read on your web page :)

  • From: Drew Colbert

    Hello.
    
            My name is Drew Colbert.  I just wanted to share my thoughts about 
    your topics.  I have seen the movie Event Horizon, and while it is 
    mainly a horror movie, it has a short bit on black holes, etc.  It 
    says that this ship, the Event Horizon, has an artificial black hole 
    in it that forms a gravity well, therefore adjoining two points in 
    space.  It also says that when they are joined you pass through a 
    portal to bring you to the other part of space.  I probably no squat 
    compared to your fellow theorists, yet wouldn't they be at the bottom 
    of the gravity well, with several stellar objects bombarding the ship, 
    if the black hole was activated inside the ship?  As well the gateway 
    is supposed to be through the black hole as people pass through it.  
    That seems a little far-fetched.  There's always going to be all of 
    this dimension passing stuff with a purple vortex people go through in 
    movies and other shows.  They should really tell the facts.
                    I would also like to comment about the speculation on negative 
    speed.  In most cases, anything negative is the opposite, yet 
    decellerating is obviously not the answer.  Dan's equation says that 
    after infinity, negative numbers appear.  So, for going -200 MPH, he 
    might need to do 200 MPH faster than light, our universal infinity.  
    Then -200 MPH might mean you go back in time to when you were going 
    the speed of light, which was infinity.  AW, what am I saying?                  
                    Well, I have one question. How do you go through a wormhole?  Is it 
    near the black hole or straight to it?  Do you disappear while being 
    sucked in?
    
    I love your page and keep on posting theories.
    
    

  • From: Matt Kuphaldt - About the music of the Fourth Dimension

    Your page is probably very cool.  I've read a few of the theories, and 
    they're interesting.  Unfortunately, I'll probably never go there again.
    
    See, your music plug-in overrides the volume control on my computer.  
    Every time I go to a new page within the site (or even back to an old one), 
    out come tunes of varying quality, blasting the innocent patrons of an 
    otherwise peaceful computer lab - regardless of how I last set the sound 
    controls.  And nobody needs to hear "Twilight Zone" one more time.
    
    If you want sounds to automatically play, sure, go for it.  I usually 
    have my computer's volume turned off for that reason.  But your program 
    thwarts my desires and rages against me and those close to me.  I know 
    I'm not the only one who shares this sentiment.

  • From: Maurice Mitchell - Gravity is a push

    First is to realize the shadow effect is really from the basic particles
    that make up your and my mass and the basic particles of the Moon and
    the Earth.  The incoming basic particles mostly miss everything when
    going through the Earth.  The basic solid core of the basic particles is
    like one to 90,000 times the effective diameter of the sphere of
    influence the basic particle has.
    
    So most particles go right through the Earth.  Newton's calculus states
    the sum of the shadows of the basic particles of the Moon and Earth act
    as if they were all at the center of the Moon and Earth.
    
    If Newton's Calculus is correct, then the shadows and mass of the basic
    particles can be considered to act as if they were all at the centers.
    

  • From: Al Hunt

    Your powerful rocket achieves a velocity exceeding the speed of light
    within a few moments. Since that isn't possible, the question is absurd.
    The answer is everywhere! This is like the problem of localizability in
    theoretical physics. If the photon moves at the idealized velocity of c,
    no time passes for it and by quantum mechanics' uncertainty principle,
    it is in no particular position in the spacetime continuum; thus it is
    in contact wih every spacetime point of the 4 manifold. Every photon in
    the universe is in contact with everywhere in the universe. In order to
    avoid this enigma physicists like Dirac invented even stranger devices
    like delta functions which are infinite at a point but zero everywhere
    else. Some avoidance. Of course, we can introduce exotic geometries like
    wormholes to mimic the intent of your enigma 6, but these are
    hypothetical constructs that are fraught with their own absurdities.
    Also, we can lean on Special Relativity as you mention and talk about
    from whose perspective is the velocity being assessed. Relative to the
    rocket ship frame there is no theoretical limiting velocity. I.E. if you
    accelerate for a few years at the rate of gravity, you will achieve
    velocities far exceeding that of light. For external observers though
    you just shrink and disappear only to reappear at a distance slightly
    less than what it would take a photon to travel. The enigma here is can
    you beat a photon in a race. To this day this is a controversial issue
    and remains unclear. We have no knowledge of photon structure, what it
    means to move in the continuum, or even what is the continuum.
    Similarily we don't know what the constituents of the magnetic field
    are. At every level of physics even quark level where for practicality
    purposes the photon is asserted to be composed of a quark-antiquark pair
    in a specially bound state, entities like photon or magnetic field are
    assumed as infinitely divisible givens. You don't ask what they are, you
    only ask what they do. Some ontology. So, your enigma is wrongly posed,
    the idea is based on a wrong perception (semi-classical approximation),
    and what is really going may not be determinate at all. Now there is an
    enigma!

  • From: Chris Jurgenson - about the doubler Enigma.

    I have to argue your solution to the doubler enigma. The box would never 
    be half full because in order to be so it would have to have an even 
    number of balls to be divided into an integer. Since you can't have 
    half a ball put into the box it will always contain an odd number of 
    balls since the number of balls will be equil to the sum of 2^n as n goes 
    from 0 to 360, for the # of minutes passed. The fact that one ball is 
    added first makes the sum at every minute an odd number. As a result the box 
    will be just a little more than half full at 5:59.

  • From: Matt Miller(No email address given) - About Dan's Time Travel theory.

    First off, I agree that, of course, time cannot move at the speed of
    light.  They are fundamentally different 'things' and time is used to
    measure velocity.  Thus, it just doesn't work that way.  However, you
    are forgetting Einstein's Relativity.  It has been proven that the
    faster one moves, the more time slows down .
    If you reach the speed of light, there would be a complete conversion of
    matter into energy because mass increases as speed increases and energy
    use increases as mass increases.  This can be represented by an
    asymptotic curve as one approaches the speed of light.  Theoretically,
    that speed cannott be reached but if it were, it would require infinite
    energy, which would be the conversion of the infinite mass of the moving
    object.
        Anyway...  If you are able, somehow, to move faster than light, a
    simple extrapolation from the equations shows that you would move
    backward in time.  This is because velocity of an object affects the
    space-time continuum(as Einstein coined) in such a way as to curve
    time.  
        On the other hand, if one were to reach an infinite speed, one  would
    never stop, and I rather think that this would be detrimental to the
    universe as a whole, in that infinite speed would mean that you would be
    everywhere at once in the entire universe.  Infinite speed, due to the
    warping of time and space by velocity, implies a singularity.  Put the
    two together and you have the entire universe becoming a singularity,
    and this is, to say the least, a rather bad thing. :)  
        That's all for now.  Later!
                -Matt Miller
    

  • From: Sharon Brumm

    I also think in this manner.  We only realize a line from one point to
    the next, but if we shift our position, the line shortens and we could
    consider it a shorter distance.  It is only from the position of objects
    which are stationary outside of us that we can mark the actual distance
    of the line, using geometry.  If space were curved, we wouldn't notice
    it.  When we look at a star, we only realize it to be a line's distance
    away from us when actually the star could be a reflection on a gigantic
    mirror that's just outside our solar system.  one could go so far as to
    infer that all of reality is just a mirrored reflection and this would
    fit in nicely with your theory.  One could start travelling to a star
    and, for all we know, it could take only half a light year to reach, or
    longer than a calculated time/distance, because apace is curved in some
    bizarre way.  The only way I think anyone will be able to say where
    things lie for sure is to experience them.  In our physical world, this
    is near impossible because each individual lies directly outside
    everything else, but there is a way:  astral projection is one way that
    I know of to slip into objects and experience them directly.  I don't
    know.  There has to be a better way.  Mystery and Science are married,
    you know.  If you want to, you can e-mail me
    


  • From: Christopher T Jurgenson
    I have a couple of ideas on multi-dimensional shapes you may find 
    interesting.
            The first is on the hypersphere. Now on your web page you state 
    that we can't know what something in the fourth dimension looks like 
    since, well, we live in 3 dimensions (R3). I have to disagree, and the 
    reason why is because living in R3 gives us access to see things in R0, R1, 
    R2, and R3; (for my point) being a point, line, circle, and a sphere 
    respectively. With this we can see that four things happen as we go from R2 
    to R3. 
            1) A shape in R3 is made up of an infinite number of 
    "corresponding" shapes in R2.
            2) As the infinite number of R2 shapes extend out to the limit 
    (here radius) of the R3 shape along the "new" axis they get smaller and 
    smaller until they reach a point.
            3) The infinite number of R2 shapes intersect each other in order 
    to create the shape in R3. The intersection is actually an element of R1. 
    Here it is a line which has been bent around to make a circle. At this 
    point making a drawing would help.
            4) As a shape in R3 passes through R2 an observer in R2 will see 
    it as a shape translated to a corresponding shape in R2 starting as a 
    point, growing to a maximum, and shrinking back to a point.  
            
            Since these rules are consistent for jumping through the 
    dimensions we do know, I find it reasonable to believe that they are 
    congruent for jumping into dimensions we do not know.
            Therefore we can postulate that a hypersphere is made up of an 
    infinite number of spheres who's intersection is a circle. Imagine a 
    sphere of radius r with an infinite number of spheres (noted set 1) around 
    its center who's centers are an infinitely small (here out noted dx) distance 
    away from the first sphere's center. These spheres will have a radius of r 
    minus dx. Each of these spheres in set 1 will have a sphere who's center is dx 
    away from their center and who's radius is r minus 2dx. These spheres belong 
    to set 2. This continues until we get to set infinity which is made up of 
    spheres with a radius r minus infinity*dx, a bunch of points. The 
    hyperradius of the hypersphere is dependent on the radius of the sphere 
    which is in the center of it. And, what do you know, we have again a 
    congruency since the radius of a circle yields the radius of a sphere. 
            The first argument that I can think of to this is that it would 
    appear that we have objects in the same space at the same time, but 
    keep in mind that this "invasion of space" is actually acomadated by the extra 
    dimension.    
            The hypervolume of this thing would be the infinite sum of diminishing 
    spheres from both ends of the new dimension times dr; that is, int 
    (4*pi*r^3)/3 from -r to r dr = (2*pi*r^4)/3    
    
            
    Consider the argument I have for the quintichypersphere. It is much more 
    difficult to understand this one but here goes...
            In keeping with the rules of congruency before mentioned we know 
    that the quintichypersphere (qhs) is made of on infinite number of 
    hyperspheres and that their intersection with each other is a sphere. If 
    you have a picture of what a hypersphere looks like in your head already 
    then we can go on. The center of each hypersphere will be dx from the 
    center of the hypersphere preceding it until you get to the first 
    hypersphere. Let's call the first set of diminishing hyperspheres from 
    the center one QSet 1. This is analogous to the idea mentioned before. Since 
    the hypersphere radiates out diminishing spheres to a point, we find that in 
    the qhs the center hypersphere's diminishing spheres are circumscribed by 
    the diminishing spheres of QSet 1, and so on. Again we have congruency with 
    the assumptions made earlier. 
            The volume of the qhs will be the infinite sum of the 
    hypervolumes from both the positive and negative ends of the fifth 
    dimension times dr. As you can see there is a pattern here. The volume 
    of a multi-dimensional "sphere" where the dimension is greater than 3 
    is equil to 2^n-3 int (4*pi*r^3)/3 (dr)^n-3 from 0 to r, where n is the 
    dimension we are refering to. Note that the wedge product is not used for 
    dr, since if it were the nth dimensional hypervolumes would all be 0. 
    In order to find the nth-dimensional hypervolume of a shape in 
    dimension n one must find the volume of the "corresponding" shape in 
    dimension n-1.;
            That's about it. Write back if you can. I'd like to hear some 
    criticism on this.
