Antara einstein and newton, yg mana korang vote

how's that so?


okay now moving on... yg you cakap pasal euclidan tu , telah mengingatkan saya pada Euclid seorang mathematician Greek , kan? so apa philosophy di sebalik pernyataan you tadi tu?
it is interesting indeed.

mase einstein publish Annus Mirabilis papers mase tu dia tak terkenal lagi, ramai saintis still ragu2 theory dia... However, in May 1919, a team led by British astronomer Arthur Stanley Eddington claimed to have confirmed Einstein's prediction of gravitational deflection of starlight by the Sun while photographing a solar eclipse in Sobral, northern Brazil, and Príncipe. On 7 November 1919, leading British newspaper The Times printed a banner headline that read: "Revolution in Science – New Theory of the Universe – Newtonian Ideas Overthrown". cian newton ideas dia kena overthrown hehe... cuma pikiran einstein ni terlalu genius in cara berfikir

memang betul... tesla memang hebat dari segi invention.. dia banyak buat revolution in electrical, ac current, wireless, ac motor.... "The man who invented the twentieth century"... tapi pelik la dia mcm tak terkenal je hehe

Philosophy d sebalik Euclid?
Ade ke aku ckp ape2 psl philosophy?

We realise yg Euclid ni famous ngan axiom geometry die... Zaman2 die dulu, org bru nk explore the nature of space, and apparently, nk explore bende2 abstrak mcm ni, kite kene observe sekeliling.. Then only can we draw out the laws that govern things that are happening around us...

And so Euclid put axioms yg menjadi asas kepada theorem2 yg lain... And based on theorem2 ni, Newton formulated his Laws of Motion that take into account the flow of time... So klu tgk link ni, apparently, Newton's Laws of Motion must take place in Euclidean space!

And since Euclid formulates axiom die based on observation kt sekeliling (that is, on Earth), Newtonian Physics then must be valid on Earth... Since kite baru bina bende2 on Earth, aku ckp engineering kite Euclidean...  

So in short, tiap kali org ckp psl Euclidean, we have to keep in mind Euclidean space...



Later in relativity, we have to not that space around earth is not really Euclidean. However, Euclidean approximation still applies. And hence Newtonian Mechanics still applies. Imagine klu kite kene construct bangunan kt black hole (which is impossible), kite xkn dpt gune F=ma lagik....

ahahaha... sampai cmtu skali....

Kene ingat yg Newton xdela salah super...

Klu bace paper die, Principia Mathematica, muke surat awal lagi die dh kate yg 'space is constant, time flows at constant rate'... Psl mse tu die xtau lagi... Klu buku tu publish sekarang, Prof fizik bace muke surat tu je, terus Newton dpt F...


Tp klu tengok citer die, Newton start pening lepas die buat gravitation. Die ramal yg bintang2 sume mesti bekumpul kt 1 tempat klu gravitation tu wujud... And die yakin gravitation wujud... N die dh expect yg universe ni expand supaye bintang2 x jatuh antara satu same lain... Tp klu universe expand, space is no longer constant, n 1 buku Principia die salah...

Last2.... 'Bia r orang lain plak terangkan... Dh beruban2 aku buat bende ni.... Pening daaaa.....'



So Newton jumpe tukang tilik... Tukang tilik tu kate.... 'Akan lahir seorang kerani yg akan musnahkan sume teorem2 kamu.....'

Newton mengamuk, pastu die bunuh tukang tilik ni.... N die bunuh sume ahli fizik mse tu, supaye xde org yg boleh lawan hukum2 die.... Die publish buku die cepat2....

Ngarut je....

tapi ada jugak yg cakap einstein punya idea relativity adalah lanjutan  daripada idea mamat ni Henri POincare .....so? cam ner ni u all

~ connection connection James Burke!

Apparently, Special Relativity boleh dikatakan bukn datang dr Einstein.

Long have been physicists startled with the result of Maxwell: speed of light is constant. Since sume ahli fizik percaye kt Newton, diorg hanye anggap bende ni sebagai 'mainan' mathematica equation. One of them would be Lorentz, yg telah propose Lorentz Transformation. Die predict bende ni dulu...

N seorang ahli fizik dr Australia (x ingat nme) juge dh jumpe E=mc^2 as a result of Lorentz Transformation, long before Einstein published his work. And once again, scientist society anggap ni sebagai mainan equation...

What Einstein did was jadikan speed of light is constant sebagai 1 teori asas... So sume bende yg follow postulate ni based on theory ni... And also, ahli fizik mule percaye teori ni based on Michelson-Morley experiment, which indirectly found that the speed of light is a constant... So Einstein yg dpt nme....



But, for General Relativity, it came mainly from him. General Relativity started from 'free falling frames are inertial frame', which sounds more like relativity...

i guess the method adopted on conducting the Morley's guy  experiment could be interesting. But then, it was Einstein who proposed that the distortion of 'light' from the stars / celestial objects  exerted by the gravitational pull when it reached the eye of an observer on Earth, should also be taken into account as to locate the  whatever / ? location of the stars? - and this is what i found interesting...he connects two elements together, associating one another , and was able to clearly defined the interaction between the two that make this u know incredibly prudent and you know interesting.

aku_EnSeM

Yea...

really, the idea of distortion of light came from his principle of equivalence...

physic

einstein pernah kata...ahli physics yang teragung selapas newton ialah Maxwell...

aku_EnSeM

ye ek...

mungkin psl Newton ni ayah kepade particle, n Maxwell plak ayah kepade field theory...

However, it is accepted yg ahli fizik plg berpengaruh sepanjang zaman adalah......... jeng jeng jeng....
1. Isaac Newton
2. Albert Einstein
3. Stephen Hawking

stephen hawking ni dari lahir ke dia ni lumpuh... tapi buku dia pasal SPACE AND TIME  tu kau ada? dengar cite buku tu penah ranking jualan terbanyak seketika dulu

aku_EnSeM

owh, aku ade buku die.. dlm buku tu pun die citer cmne die leh dpt penyakit tu..

basically, doktor suspect die ade penyakit tu mse first year die kt uni... die sihat je sebelum tu, comel lg...

then, klu xsilap, mse die nk buat PhD, bdn die start lumpuh...
