Саг хугасаа

(Саг-һээ шэлжэн эльгээгдэбэ)

Саг хугасаа үнгэрһэн, модоо, ерээдүй[1][2][3][4][5][6] гэһэн гурбан хэмжээсэтэй байха ба тэдэгээрэй хоорондо үрнэжэ бай үйлэ ябадалай үргэлжэлхэ хугасаанай хэмжүүр болодог.[3][7][8] Эртэһээ нааша саг хугасаанай тухай ойлголтонь шажан болоод шэнжэлхэ ухаанай гол шухала һэдэб асуудалай нэгэ байһанаар ерэһэн болоод бүхыл һалбарида хэрэглэхэдэ тохиромжотой байдалаар тодорхойложо ерэһэн болобошье эрдэмтэд үнэндээ тодорхойлжо шадаагүйл байна. Тиимэ болобошье бизнес, үйлэдбэрилэл, спорт, шэнжэлхэ ухаан мүн уралигай һалбаринуудта өөр өөрын гэһэн саг хугасаа хэмжэхэ системые хэрэглэдэг. Гэхэдээ зарим энгиин эргэлзээгүй тодорхойлолтонууд байдаг “саг хугасаанай нэгэ эгшэндэ бүхы зүйл гансал удаа тохёолдодог” “саг хугасаае сагаар хэмжэдэг” гэхэ мэтэ.[3][7][8][8][9][10][11][12][13]

Олон алдартай философууд, гүн ухаантануудай дунда саг хугасаанай тухай хоёр илгаатай үзэл баримталал байдаг. Нэгэниинь “саг хугасаа бол оршолон юртэмсын бүтэсын үндэһэн хэһэг болоод бэе дааһан зүйл юм”. Исаак Ньютон энэ үзэлтэй һанал ниилэдэг байһан болоод заримдаа “Ньютоной саг хугасаа” гэжэ нэрэлдэг байгаа.[14][15] Үүнэй эсэргүү үзэл һанаань “саг хугасаа бол ямар нэгэн үйлэ ябадал, объектһоо хамааралтай зүйл бэшэ, ямар нэгэн зүйлын урасхал баһа бэшэ болоод харин үйлэ ябадалые жэшэжэ харисуулжа дэһэ дараалалда оруулжа байдаг хүнэй оюун ухаан сэдьхэхын бүтэсэ (оронзай ба тоо дугаартай хамта) юм” гэһэн байдаг. Готтфрид Лайбниц[16] ба Иммануил Кантын[17][18] энэ хоёрдохи үзэл һанаанай дагуу саг хугасаа бол ямар нэгэн үйлэ ябадал бэшэ мүн ямар нэгэн зүйл бэшэ, тиимэһээ энэнь хэмжэжэ болохогүй, аялжа болохогүй зүйл юм.

Саг хугасаа бол Олон уласай нэгэжын системын үндэһэн долоон физикэ хэмжүүрэй нэгэн юм. Саг хугасаагаар бусад хэмжэгдэхүүные тодорхойлодог. Жэшээлбэл: үнсэг хурдан, тодорхой хугасаанда хэжэ бай эргэлтын тоогоор тодорхойлогдодог. Саг хугасаанай үйлэдэлэй тодорхойлолто, шудалжа хэмжэжэ бай саг хугасаае тодорхой стандартаар тогтооһон өөр нэгэ дабтамжатай саг хугасаагаар хэмжэхэ шаардалга гараһан ба эндэһээ “секундые” хэрэглэхэ болоо. Энэ нэгэжэнь шэнжэлхэ ухаанай шудалгаа шэнжэлгээ болон үдэр тутамай амидаралда маша үргэн хэрэглэгдэдэг. Саг хугасаанай үйлэдэлэй тодорхойлолтонь тооложо хэмжэжэ болодоггүй саг хугасаа гэжэ нэрэлэгдэдэг зүйл гэһэн ойлголтые халажа энэ бол урдан үнгэрдэг, тооложо хэмжэжэ болодог зүйл гэһэн ойлголтые бии болгоһон. Оршолон юртэмсын үргэлжэлһэн саг хугасаанай шудалгаа шэнжэлгээнь саг хугасаан доторхи оронзайн талаархи асуудалые гаргажа ерэһэн ба энэ асуултань байгаалиин шэнжэлхэ ухаанай шэглэлые шудалжа бай оюутадай һуури ажал болодог байна.

Саг хугасаанай хэмжэлтые эрдэмтэд болон технологиин туһаламжатай тодорхойлжо навигаци болон одон орон шудалал ухаанай һуури болоһон. Мүсэлигтэ үйлэ ябадалнууд болон хүдэлөөниинь саг хугасаанай стандарт нэгэжэ байдалаар хэрэглэгдэжэ ерэһэн. Жэшээлбэл: тэнгэри дэхи наранай хүдэлөөн, һарын байрлалга хэлбэри, дүүжин һабалуурын һаблалта мүн зүрхэнэй сохилто зэрэг. Оршон үедэ олон уласай сагай нэгэжэнь “секунда” юм. Секундань цезиин атомай сасаруулха сасарагай үргэлжэлхэ хугасаанаар тодорхойлогдодог. Саг хугасаа мүн ниигэмдэ ехээхэнаша холбогдолтой, “саг бол алтан” гэһэн зүйр үгэнь үдэр хоногой үргэлжэлхэ хугасаа хизгаартай, хүмүүнэй амидарха хугасаашье мүн хизгаартай гэдэгые анхааруулжа байдаг.

We use time to place events in sequence one after the other, and we use time to compare how long events last... Among philosophers of physics, the most popular short answer to the question "What is physical time?" is that it is not a substance or object but rather a special system of relations among instantaneous events. This working definition is offered by Adolf Grünbaum who applies the contemporary mathematical theory of continuity to physical processes, and he says time is a linear continuum of instants and is a distinguished one-dimensional sub-space of four-dimensional spacetime.”

To paraphrase: Absolute, true, and mathematical time, from its own nature, passes equably without relation to anything external, and thus without reference to any change or way of measuring of time (e.g., the hour, day, month, or year).”

The Internet Encyclopedia of Philosophy. 2011-04-09 үдэртэ хандаһан. “First of all, Leibniz finds the idea that space and time might be substances or substance-like absurd (see, for example, "Correspondence with Clarke," Leibniz's Fourth Paper, §8ff). In short, an empty space would be a substance with no properties; it will be a substance that even God cannot modify or destroy.... That is, space and time are internal or intrinsic features of the complete concepts of things, not extrinsic.... Leibniz's view has two major implications. First, there is no absolute location in either space or time; location is always the situation of an object or event relative to other objects and events. Second, space and time are not in themselves real (that is, not substances). Space and time are, rather, ideal. Space and time are just metaphysically illegitimate ways of perceiving certain virtual relations between substances. They are phenomena or, strictly speaking, illusions (although they are illusions that are well-founded upon the internal properties of substances).... It is sometimes convenient to think of space and time as something "out there," over and above the entities and their relations to each other, but this convenience must not be confused with reality. Space is nothing but the order of co-existent objects; time nothing but the order of successive events. This is usually called a relational theory of space and time.”

Space and time do not exist in and of themselves, but in some sense are the product of the way we represent things. The[y] are ideal, though not in the sense in which Leibniz thought they are ideal (figments of the imagination). The ideality of space is its mind-dependence: it is only a condition of sensibility.... Kant concluded "absolute space is not an object of outer sensation; it is rather a fundamental concept which first of all makes possible all such outer sensation."...Much of the argumentation pertaining to space is applicable, mutatis mutandis, to time, so I will not rehearse the arguments. As space is the form of outer intuition, so time is the form of inner intuition.... Kant claimed that time is real, it is "the real form of inner intuition."”

The Internet Encyclopedia of Philosophy. 2011-04-09 үдэртэ хандаһан. “Time, Kant argues, is also necessary as a form or condition of our intuitions of objects. The idea of time itself cannot be gathered from experience because succession and simultaneity of objects, the phenomena that would indicate the passage of time, would be impossible to represent if we did not already possess the capacity to represent objects in time.... Another way to put the point is to say that the fact that the mind of the knower makes the a priori contribution does not mean that space and time or the categories are mere figments of the imagination. Kant is an empirical realist about the world we experience; we can know objects as they appear to us. He gives a robust defense of science and the study of the natural world from his argument about the mind's role in making nature. All discursive, rational beings must conceive of the physical world as spatially and temporally unified, he argues.”
