universal mathematical laws?

Question

How did universal mathematical laws evolve from or with the big bang? Can grasp how we are made from star dust but where were mathematics lurking/evolving, all that time?

Answer 1

At the top of the list of science's unanswered questions, like what is consciousness and how did life begin, is the deepest mystery of all: Why does the universe appear to follow mathematical laws?

According to the Big Bang theory, matter, energy, space, and time were created during the primeval explosion. Instantly, it seems, everything began unfolding according to a mathematical plan. But where did the mathematics come from? What are the origins of numbers and the relationships they obey?

The ancient followers of the Greek mathematician Pythagoras declared that numbers were the basic elements of the universe. Ever since, scientists have embraced a kind of mathematical creationism: God is a great mathematician, who declared, "Let there be numbers!" before getting around to "let there be light!"

Scientists usually use the notion of God metaphorically. But ultimately, most of them at least tacitly embrace the philosophy of Plato, who proposed, rather unscientifically, that numbers and mathematical laws are ethereal ideals, existing outside of space and time in a realm beyond the reach of humankind.

Because the whole point of science is to describe the universe without invoking the supernatural, the failure to explain rationally the "unreasonable effectiveness of mathematics," as the physicist Eugene Wigner once put it, is something of a scandal, an enormous gap in human understanding.

"We refuse to face this embarrassment," Reuben Hersh, a mathematician emeritus of the University of New Mexico, in Albuquerque, wrote in his recent book, "What Is Mathematics Really?" (Oxford University Press, 1997). "Ideal entities independent of human consciousness violate the empiricism of modern science." While science is anchored in observations of the physical world, Hersh insists that mathematics is more of a human creation, like literature, religion, or banking.

Hersh's book is one of several recent works contending that mathematics is not an ethereal essence but comes from people who invented, not discovered it. The sentiments presented in the books are not entirely new and the mathematical puzzle has hardly been solved. But the idea of a human-centered mathematics may be gaining force and respect.

In "The Number Sense: How the Mind Creates Mathematics" (Oxford University Press, 1997), Stanislas Dehaene, a cognitive scientist at the National Institute of Health and Medical Research, in Paris, marshals experimental evidence to show that the brains of humans -- and even of chimpanzees and rats -- may come equipped at birth with an innate, wired-in aptitude for mathematics. Gregory Chaitin, a mathematician at IBM's Thomas J. Watson Research Center, in Yorktown Heights, N.Y., takes an anti-Platonist stance in "The Limits of Mathematics" (Springer, 1997). Two Berkeley scientists, George Lakoff and Rafael Nunez, are working on a book tentatively called "The Mathematical Body," contending that even the most abstract mathematical concepts arise from basic human experience -- from the way the body interacts with the world. They gave a preview of their ideas in a chapter of another book published last year: "Mathematical Reasoning: Analogies, Metaphors and Images," edited by Lyn English (Erlbaum).

The authors are all working mathematicians and scientists, not postmodern critics viewing the territory from afar. They emphatically reject those who try to dismiss mathematics and science as arbitrary constructions, or white male Eurocentric folklore. But they are just as adamant in rejecting what most mathematicians and many scientists have come to take for granted: the Platonic creed.

"The normal notion of pure math is that mathematicians have some kind of direct pipeline to God's thoughts, to absolute truth," Chaitin wrote in "The Limits of Mathematics." While scientific knowledge is tentative and subject to constant revision, mathematics is usually seen as eternal. But Chaitin called on his colleagues to abandon mathematical Platonism and adopt a "quasi-empirical" approach that treats mathematics as just another messy experimental science.

"Quasi-empirical," he said, "means that math ain't that different from physics." This view is laid out in detail in a revised edition of "New Directions in the Philosophy of Mathematics," edited by Thomas Tymoczco (Princeton University Press, 1998).

Leopold Kronecker, a 19th-century mathematician, once said: "The integers were created by God; all else is the work of man." Albert Einstein, taking a different view of whole numbers, wrote that "the series of integers is obviously an invention of the human mind, a self-created tool which simplifies the ordering of certain sensory experiences."

In "The Number Sense," Dehaene went even further. The integers -- the smallest ones, anyway -- are hard-wired into human nervous systems by evolution, along with a crude ability to add and subtract. Mathematics, he believes, is "engraved in the very architecture of our brains."

"Because we live in a world full of discrete and movable objects, it is very useful for us to be able to extract number," he argued in a recent forum published on the Internet (www.edge.org) by the Edge Foundation. "This can help us to track predators or to select the best foraging grounds, to mention only very obvious examples."

By studying brain-damaged patients who have lost basic number skills, Dehaene and others have tentatively traced this arithmetical module to an area of the brain called the inferior parietal cortex, a poorly understood location where visual, auditory and tactile signals converge. Scientists are intrigued by clues that this region is also involved in language processing and in distinguishing right from left. Mathematics is, after all, a kind of language intimately involved with using numbers to order space. The inferior parietal cortex also seems to be important for manual dexterity, and arithmetic begins with counting on the hands. Imaging experiments, in which people's brains are monitored as they calculate, point to the same region as a primitive number processor.

If this neurological calculator has indeed been bequeathed by evolution, then traces of it should be found in other species. In making his argument, Dehaene draws on experiments over the last few decades suggesting that even rats have a rudimentary number sense. The animals were taught to press lever A four times and then lever B to get food, or to press lever A when they heard a two-tone sequence and lever B when they heard an eight-tone sequence. (To insure that the rats were responding to the number of signals and not just to their duration, the two-tone sequence sometimes lasted longer than the eight-tone one.)

Even more striking were later experiments in which rats were first trained to associate lever A with two tones and lever B with four tones. Then they were taught to associate A with two flashes of light and B with four flashes. If the rats heard two tones and saw two flashes they learned to push B, not A. They seemed to have comprehended the notion that two plus two equals four.

The rats were not precise. Trained to press one lever four times, they often pressed it five or six times, expecting to be rewarded just the same, or they confused a seven-tone sequence with an eight-tone one. But the experiments support the notion of a primitive neurological number processor, even in rodents.

In other experiments, chimpanzees seemed to learn simple arithmetic. Given a choice between one tray with a pile of three chocolate chips and another pile of four and a second tray with piles of two and three chips, they chose the first tray with the most candy. But when the totals on the trays differed by only one chip, the chimps were less likely to make the discrimination. The number sense is approximate, not exact. More recent experiments on infants, using Mickey Mouse toys instead of chocolate chips, found signs of the same kind of rough numerical ability in babies less than 5 months old.

Dehaene says this instinct is innate, as singing is for songbirds or spinning webs is for spiders. Numbers are not Platonic ideals but neurological creations, artifacts of the way the brain parses the world. In that sense they are like colors. Red apples are not inherently red. They reflect light at wavelengths that the brain, as it was wired by evolution, interprets as red.

While people are born with an understanding of the rudiments of arithmetic, he contends, going beyond that requires learning and creativity. Multiplication, division, and the whole superstructure of higher mathematics -- from algebra and trigonometry, to calculus, fractal geometry, and beyond -- are a beautiful improvisation, the work of human culture.

The ability to weave simple ideas, like two plus two equals four, into the tapestries of higher mathematics, he suggests, is not unlike the human skill for language. People take a relatively small collection of words and, using a few simple rules of grammar and syntax, create literature.

At the University of California at Berkeley, Lakoff, a linguist and cognitive scientist, and Nunez, a developmental psychologist, contend that the source of mathematics lies not just in the brain but in the human body and the physical world. People favor number systems based on 10 because they have 10 fingers and 10 toes. But that is just the beginning of the story.

Driven by a built-in number sense, the theory goes, primitive people explored the wonders of counting by playing with their fingers or putting rocks in a pile. But they found that counting could also be thought of as taking steps along a line to measure distance. That metaphor eventually allowed for the invention of more abstract concepts. Walk one way and you get the positive integers; walk the other way and you get the negative integers. The starting point is zero.

Multiplication by a positive number can be thought of as stretching; multiplying by a negative number makes something shrink.

Lakoff and Nunez call these "grounding metaphors." In inventing mathematics, they contend, people also used "linking metaphors" to connect two sets of ideas. The sequence of numbers can be mapped onto the notion of a line. Now numbers are not fingers or rocks but points. Put two lines together at right angles and you get what mathematicians call a Cartesian plane, a two-dimensional graph that opens up a whole new arena to play in.

And so, floor by floor, the tower of mathematics is built. "Students never learn that mathematics is a creative endeavor," Lakoff said in a recent interview. "Mathematics is more glorious because it is humanly constructed." There is no such thing as pure mathematics or pure thought, he said -- they are physical activities.

That does not mean that mathematics is a relativistic free-for-all. The most basic mathematical inventions are rooted in the brain and body. Even mathematicians' loftier elaborations are tested against the universe. Of the infinite range of mathematical creations, scientists keep those that help them explain and predict reality. Mathematicians savor the others as ends in themselves, like paintings or symphonies.

But many scientists and mathematicians still doubt that evolution -- biological or cultural -- can adequately explain why mathematics works so well in describing the fundamental laws of the universe.

"Our ability to discover, and describe mathematically, Newton's equations has no immediate survival value," said Dr. Paul Davies, professor of mathematical physics at the University of Adelaide, in Australia. "This point has even greater force when it comes to, say, quantum mechanics. The reason people find it hard to understand quantum physics is precisely because there is no survival value in being able to do so."

The reason mathematics is so effective, he says, remains a deep mystery. "No feature of this uncanny 'tuning' of the human mind to the workings of nature is more striking than mathematics," he wrote in "The Mind of God: The Scientific Basis for a Rational World" (Simon & Schuster, 1992).

Some hold out vague hopes that the mystery might be solved if humans ever encounter an alien civilization. If mathematics is indeed universal and eternal, the theory goes, then the aliens would understand concepts like pi, the ratio of a circle's circumference to its diameter. The Platonists' assume that there is "pi in the sky," as the British astronomer John Barrow said in a book by that name (Oxford University Press, 1992).

The anti-Platonists say there is no reason to believe the aliens would understand mathematical inventions from Earth. "The Platonist claim that every intelligence must produce prime numbers, pi and the continuum hypothesis is an example of simple anthropomorphism," Hersh said.

But if earthlings were utterly baffled by extraterrestrial mathematics, would the anti-Platonists have proved their point? Not necessarily.

"Alien intelligences may be so far advanced that their math would simply be too hard for us to grasp," Davies said. "The calculus would have baffled Pythagoras, but with suitable tuition he would have accepted it."

But what if the humans and the aliens could communicate mathematically? Would that decide the issue in favor of the Platonists? Not really.

"If the alien species had evolved in an environment similar to ours -- say, a world composed of distinct, movable objects -- then most likely its brain would have incorporated, through natural selection, the same regularities about the external world as we have," Dehaene said. "Thus, it would have a very similar arithmetic and geometry.

"But now, suppose that the alien species has evolved in a radically different environment, like a fluid world," he continued. "Then knowledge of movable objects would not be essential to its survival, while knowledge of fluid mechanics, vortices, etc., would be. I believe that this hypothetical species would have internalized in its brain regularities strikingly different from ours. Hence it would have radically different mathematics."

And so the argument continues to churn.

Several years ago, the French mathematician Alain Connes, arguing for the Platonists, and the French neurobiologist Jean-Pierre Changeux, taking the opposite side, tried to settle the matter with a debate. The result, translated and edited by M.B. DeBevoise, was the book "Conversations on Mind, Matter, and Mathematics" (Princeton University Press, 1995).

Ranging over a vast field of topics including relativity, quantum mechanics, neurobiology, topology, game theory, information theory, and non-Euclidean geometry, the two reached the end of their discussion with no resolution.

The best they could do was to agree to disagree.

Answer 2

Universal mathematic laws are constants of the known universe like 1+1 = 2. They did not evolve, they were discovered, and our understanding of them evolved. Laws like E=mc squared existed since moments after the big bang. There just weren’t any creatures around to observe them. This is similar to the old question if a tree falls in the woods and there is no one there to hear the sound, will it still make a sound? In the physical and real universe it will make a sound, since physics is independent of the observer. In the concept of thought where the observer is the center of the universe then nothing happens unless there is an observer to observe it.

Math is, it is just there, and it has been there since there was an Universe. Now inside a black hole, moments before the big bang, or when traveling faster than the speed of light the laws of nature, physics, and math no longer apply. In that case then new math would have to be developed to explain what is happening. Of course since black holes do exist that math, if there is a math that can explain, what is happening on the inside of the black hole is already there inside the black hole.

We cannot observe that math because it is unable to make contact with our universe. Every black hole has a radius called the Event Horizon. For information to pass beyond the event horizon it would have to exceed the speed of light and since it can’t we don’t receive it. That’s why all black holes are decently shrouded in event horizons so we cannot see the break down of physics and modern math.

Answer 3

Interesting question!

The best analogy I can come up with is the thought that before Newton came about, people on Earth used to just float through the air... they weren't held down to the ground because gravity hadn't yet been discovered.

Asinine thinking? Of course. Gravity existed before Newton, it merely hadn't been discovered. Mathematics is the same way. Universal mathematical laws have always been in existence, also just waiting to be discovered.

I wasn't there, but my guess would be mathematical laws pre-date the Big Bang. They haven't evolved in the least... they've always been there, just waiting for some bright being to figure out they've been there.

Answer 4

Choas theory is one answer. What we understand mathematically has arisen with no mathematical calculation: its a feedback loop, of variable stability, continually adding to itself, and branching in a million directions. Everything is part of one event, which science calls a singularity.

The Big Bang is conjecture, because events before the Planck time cannot be extrapolated from the laws of physics (its too hot). The singularity is empirically and mathematically derived, and thus the beginning of the story science can tell.

The 3 dimensions we can discern (and millions of others we can't) are relationships between pieces of stable energy called particles, with charges 1, -1, 2, -2, 3 and -3. Their random arrangements vary in stability. It is the chaotic destruction of the unstable that leaves us with the order we see. The way quarks and electrons, or dimensions interact can be understood with mathematics. But they don't do maths. Only a brain can understand. The laws of maths are all simple. Underlying the most complex organism is a set of simple relationships. Calculus, for example, is a (very clever) derivation of addition.

Answer 5

Mathematics are the product of an observer. Before measurements were taken and qualities and quantities were compared, there was no mathematics.Mathematics are the result of a mind existing that has sufficient anayltical power to ask questions and attempt to make predictions based on available data.

Math is not a force or power like light or gravity. Math is what we use to try to comprehend things.

Math is really just another language.

Answer 6

if you're talking about physical laws such as gravitation and electromagnetism, i'm not sure there is a definitive theory as to "why" they are the way they are. it just happened that way. mathematics is simply a tool we have invented to describe our observations of these natural forces, so "mathematical laws" didnt really evolve, they were just changed by humans as we learned more about the universe.

Answer 7

the universe does not follow mathematical rules, man made teh math so he could better understand the universe. math is a language, just like ABC. but math is the language of engineeering, it allows us to "build things" without killing anyone, it allows astronauts to have a planet to land on then they get there, and we can put those numbers to many uses, and learn many things without leaving our desk, spending any money, or killing anyone in the process.

math is math, from adding up the shopping list to calculating the fuel requirements for interplanetary travel...its all there from 0-9. its how we apply those numbers which makes them do work for us, so we dont have to!

Answer 8

slightly pretentious are we? How do you recognize what rules go beyond the universe? The rules of the two good judgment and physics are ultimately in line with theory and assumption. you're saying the truths are absolute. Supposing in the seventh or 8th measurement, it fairly is real that 2+2 = 5? I doubt that any God exists. yet whilst one did, that God would not be limited via any rules that govern us. AS for Nigel Bovey - eliminate the assumptions, misconceptions and falsehoods - and you're left with lavatory paper coated in vast words he would not comprehend the meaning of!

Answer 9

I think tuthutop is on to something! The laws exist outside of the physical universe as they are laws, or principles. Though maybe their effect make be seen in the physical!

Does that make them ethereal? Bit beyond my contemplation.

Answer 10

I don't think that mathematics are considered to be part of the physical universe. They have simply been found to accurately describe it.

Answer 11

Mathamatics is the purest of all sciences because it has no base, it was derived from nothing. All other sciences derive certain basic principles using mathamical principles (manly calculus) making them to be ipso facto derived from mathamatics.
