  • Spontaneous Creation Problems
    An assignment of causation does not exclude the possibility of other things having the same effect. So in the example above, saying that heat causes water to boil does not exclude the possibility that something else as well, such as a drop in pressure, could also cause water to boil. That A is judged to cause B does not exclude the possibility that something else might also cause B as well.Metaphysician Undercover

    Now, I ask you to use logic, and see with your mind, logically, that it is possible for there to be time passing without change occurringMetaphysician Undercover

    This reflects what Minkowski spacetime infers. This is referred to as being at rest in a particular frame of reference.

    However, time passing, itself, is not observed.Metaphysician Undercover

    Yes.

    Physics is very much invested in causality -- which is the prize of metaphysicsL'éléphant

    I love causality. Most of the math exploration I do these days is mathematical analogues of causality chains in the complex plane. So, is philosophy very much invested in physics? Should it be? Is philosophy equipped, in general, to circumvent details and pull quantum tricks out of its big hat?

  • Spontaneous Creation Problems
    Virtual particles are not, currently, "directly observable." They have effects that can be observed, which is why the idea has gained currencyCount Timothy von Icarus

    In the one-dimensional Casimir Effect one could encounter the Harmonic series, which does not converge. By manipulating this series one can derive a convergent series (where the expression 1/12 might pop up) corresponding to measurements. The magic here could be interpreted as the effects of virtual particles. Or more or less as I "understand" it. Pop science keeps pushing the notion, but I suppose a physicist might also. This is strange territory where philosophy can't seem to abstain trespassing. :chin:

    I don't see the Syndrome in play here. Once he began going to religious meetings with his wife a new personality began to evolve. He was welcomed into that community with open arms. He found a path that became more attractive the longer he followed it.

    Sometime later he told me, "I used to worry so much about so many things and my life was meaningless, but now when a problem arises I put myself in God's Hands and let him guide me."
  • A first cause is logically necessary
    When one forms a causal chain mathematically, one can assume that at each step a single causal function exists. But in the real world a host of causal "forces" may be in play at each step, and somehow they must average out to prolong the expansion. Here is an attempt to corral those forces in the simplest mathematical structures.

    Note that this looks at causal expansions starting at an original cause and moving forward through time.

    If math is not your ticket, ignore the above. :cool:

    As much as I can recall this is a true story, perhaps inaccurate where my memory fails. He and I were bouldering companions while I got my doctorate and he got his masters at the same institution. We would go climbing together two or three times a week around 1970. At least at that time there were some real differences between the religions. However, the Catholic Church has moderated a bit over the intervening years.

    I haven't talked with him in years. But I see EWTN has a fairly recent hour long interview with him and his wife. They were Pentecostals before Catholics, I see. He worked with a Watergate conspirator turned preacher at some point.

  • I’m 40 years old this year, and I still don’t know what to do, whether I should continue to live/die
    A long time ago a good friend of mine, a young man at the time, inhabited a world that was falling apart - or so he perceived it. He had no job, despite an advanced degree in the sciences, his wife threatened to leave him and take their two small children. He was at wits end.

    His wife, a devout Christian, insisted on him joining her father's church (her father was pastor), or she would leave. He gritted his teeth and joined the church - and focused on acquiring the "belief" upon which the church was founded. In other words, he told himself, "You will believe what they believe".

    Some would say, You can't believe something you don't believe down deep - it will always be a superficial belief. But my friend would prove them wrong.

    He not only came to strongly believe the faith, he became a missionary, working with prison inmates along the Gold Coast of Africa. He spoke with President Reagan about his work.

    Now, here is the truly odd part of the story. His church was protestant, and my friend wrote published articles about the dangers of Catholicism. Then, one day, he and his wife and family converted to the Catholic faith, and he became a Deacon of the Church, working with the homeless.

    If you make up your mind to believe, it's not an impossibility. And it's a possible way out of your dilemma.
  • Time travel to the past hypothetically possible?
    If one looks at a kind of causation chain that has taken one from birth to the present, at each temporal step a host of causes converges to form the next step, not an easy thing to grasp. Stanislaw Lem had an Ergodic theory of history in which going back in time and performing an act wouldn't necessarily cause a radically different present. The fact that so many aspects of causation go into effect for a moment might mean that they "average out" and any one might have very little effect compared to the others.

    The Grandfather paradox might not be completely binding. Give it some thought.
  • Donald Trump (All General Trump Conversations Here)
    Trump appears to be in the mold of Mussolini - the arrogant stances and stern facial imagery. Back then the Italian people wanted someone to come in and bring order out of chaos, and he did, at least for awhile.

    I wouldn't be giving Trump a second glance if it were not for the imbecile who is president now and the way he opened the borders of our country and allowed hundreds of thousands to migrate here non legally. I suspect the reasoning was to flood municipalities with people who would probably vote Democratic at whatever levels they could. Cities, counties, perhaps states. This might shift the House into Democratic hands. Non-civilians voting in national elections is problematic.

    The irony is that the big Democratic sanctuary cities are losing high income tax payers to be replaced with homeless and welfare subjects.

    Don't pay any attention to me. I'm old and doddering, the third stage of the Riddle of the Sphinx.

    Allow n to increase without bound (go to infinity) in the infinite composition (regression) , which is an analogue of a cause/effect sequence. As n increases the value of this expression (the left hand end if you like) approaches a specific complex number.

    And thus discovered/invented, together. What do you say, if you care to say?tim wood

    Creativity can enter when one speculates on new topics and definitions. If a flight of imagination leads to a new concept (if, in fact, there are any), then what flows from a logical analysis of this concept can be considered discovery. In other words, once the initiating concept is delineated, all that follows is in a sense immediately established - to be discovered. But the process of math research is almost always a sometimes convoluted combination.

    Practicing mathematicians pay virtually no attention to this philosophical discussion.
  • Numbers: A Physical Handshake with Design
    The surprising effectiveness of mathematics in making accurate, sometimes unexpected predictions about the natural world suggests a deeper connection between mathematical structures and physical reality. This view opposes the idea that mathematics is just a tool invented for practical purposes, instead hinting at some intrinsic relationship between mathematical concepts and the fabric of the universe.Wayfarer

    Could be. :up:
  • Numbers: A Physical Handshake with Design
    I hesitate to enter this conversation, but I can't resist offering a few opinions held by an actual mathematician who has done both teaching and research.

    The distinction between pure and applied math is somewhat vague, one reason being that pure math may become applied math at times. A researcher in applied math could be working on a math scheme to solve a particular problem, like calculating the stresses on a modern fighter plane during sharp turns. Or, he could be pursuing a topic purely for its own sake, curious about what comes next - and then finds someone has used his results in an applied manner.

    This happened to me. My interests are always in "pure" math (complex analysis) and I published a paper in 1991, I think, with no thoughts of it ever being "useful", only to find my principle result was employed in a multiple author sociology paper about decision making in a group. Of course, the author who cited and used my result paid no attention to the details.

    There are so many kinds of mathematicians and so many kinds of mathematics it's foolish to try to generalize. I'm guessing about 1200 PhDs are granted each year in the USA, with about half being American citizens. Probably a large majority never publish more than, say, two papers in their careers - for various reasons. But there are those, like myself, that find the exploration of new ideas fascinating.

    That's how I see myself and many others: Explorers. It's no wonder you find mathematicians among rock climbers and mountaineers.

    Pure math has connection to the natural world only as indecipherable signification representing thermodynamic equilibrium.
    Since mathematicians only use pure math for investigation of the ground rules concerning applied math, pure math is merely higher-order applied math.

    The point that I was trying to make is that if all had an equal chance of being selected individually, a smaller section of square is more likely to be selected then the larger scaled squares.Philosophim

    If we subdivide into 9 sub squares, the probability of choosing one of those sub squares is 1/9. If we have 25 sub squares, the probability of one of those is 1/25. Time to retire here, too.
  • A first cause is logically necessary
    If the past is infinite then the present is the end of an infinite sequence of events. An infinite sequence of events has no end. Therefore, the past is not infinite.Michael

  • Spontaneous Creation Problems

    Sorry. Language is a lot looser in philosophy (or this forum) than where I worked.
  • Spontaneous Creation Problems
    For every one square inch we see that has one chance out of the infinite, we have a square that subdivides down into magnitudes smaller, meaning in the comparative likelihood of one square inch, its much more likely that something appear very small. I don't want to math this out, maybe someone else could.Philosophim

    Take a one inch square. Divide each side into n equal parts. Then there are n^2 sub squares. Assume the probability of a point being in the big square is one, and each sub square probability then is n^-2. "One chance out of the infinite" means what? I have assumed the probability of finding a point in the big square to be one, but what you state implies zero probability. Thus there is really zero probability of finding a small object in any sub square.
