    book `Einstein's E = mc² Generalized'  recently published  in  from New York, USA 

Dear Sir

                I have pleasure in informing you that the book

`Einstein's E = mc²  Generalized' ,    www.AjayOnLine.us

 has been published from New York , USA by Raider Pub. Int.
In this book 102 years old E=mc² has been generalized
The basis of discussion is PEER REVIEW articles published in International Journals and presented in International Conference in USA and ENGLAND                                            

 Silent features of book Einstein's E = mc² Generalized',   

 5^th Chapter contains  45  FAQs  and concrete  based upon first Four Chapter.

             Available on Amazon.com   Price USD   7.9

 http://www.amazon.com/Einsteins-Mc2-Generalized-Ajay-Sharma/dp/1934360228/ref=sr_1_1/103-6624673-6380637?ie=UTF8&s=books&qid=1190733223&sr=1-1 

               
                                                Scientific support

 (i)    The subject matter discussed in the    book

                `Einstein's E = mc² Generalized',    www.AjayOnLine.us

 has been presented by the author in international conferences in the USA and ENGLAND in 2005-06 and has been published in PEER REVIEW INTERNATIONAL JOURNALS of research. In past FIVE YEARS  this work has been accepted for presentation over SIXTY International Conferences , all over the world.

        (ii)   In past 5 years this work has been accepted for presentation in more than 60 international conferences all over the world.

(iii)               The theme of the work is that Einstein's mathematical derivation of E=mc² as given by the legend in his September 1905 paper is inadequate. It implies that Einstein's this derivation of Sep. 1905 is true under Special Conditions not in general.

(iv)              Under some conditions Einstein's  Sep 1905 derivation predicts

Mass of body after emission of light energy

                        = Mass of body before emission of light energy + positive quantity

                   M_a    =   M_b   + 0.004L/cv – L/c²       ( v<<<c)

         (vi)  Hence more generalized equation DE = Ac²Dm has been suggested, here A is coefficient of proportionality like many others existing in physics, since days of Aristotle, Newton etc.

            (v)  It starts news discussion on the basic science.  DE = Ac²Dm is very useful in understanding the pre-Big Bang origin of the universe besides many other phenomena elaborated in the book.

                               CHAPTERS IN BOOK    Einstein's E=mc2 Generalized

Chapter 1. Physics and its Founders pages 1-42

 Chapter 2. Einstein Suggested or Speculated ∆E =∆mc² from ∆L =∆mc² pages 43-115

 Chapter 3. The Kinetic Energy, Relativistic Kinetic Energy and Rest Mass Energy pages 116-164

 Chapter 4. Derivation and Applications of the Generalized Form of Mass-Energy  Equation pages165-239

 Chapter 5. All in One: Questions and Answers (contains 45 questions and answers based upon previous chapters of book)

pages 240-298

A little known verse of the Bible reads:
And he made a molten sea, ten cubits from the one brim
to the other: it was round all about, and his height was
five cubits: and a line of thirty cubits did compass it
about. (I Kings 7, 23).. (pi=3?)
- http://www-groups.dcs.st-and.ac.uk -

Feynman:
The question of how to calculate the numerical value of
the fine structure constant from theory was one of the most
outstandingly difficult problems in mathematical physics
for the greater part of the 20th century.
There is a general connection of the quantum coupling constants
with pi which was anticipated by R.P. Feynman
- http://www.maths.qmul.ac.uk/~jgg/page5.html -

G. Novak:
How many equations could anyone write for the origins of pi"
In fact, it is the origins of pie that physicists are analyzing.
When physicists don't have anything else to do, they write
relativity equations. It's a welfare system for physicists.

Fundamental constant seems anything but
(Variation in this constant would have deep implications)
. 24 November 2007
Magazine issue 2631

A ROW over the apparent wandering ways of one of the universe's fundamental
constants has been fuelled by claims that a crucial study on one side of the
debate suffered from "basic flaws".

The story began in 1998 when John Webb of the University of New South Wales
(UNSW) in Sydney, Australia, claimed that alpha, a constant which determines
how matter and photons interact, was smaller 12 billion years ago than it is
today. His finding was based on measurements of the frequencies at which
interstellar gas clouds appeared to absorb light emitted from very bright
objects known as quasars when the universe was young.

Variation in this constant over time would have deep implications,
and some physicists say it points to the existence of the extra
dimensions required by string theory.

[http://www.newscientist.com/channel/fundamentals/mg19626314.500-fundamental-constant-seems-anything-but.html]

From one of Feynman's books:

"Immediately you would like to know where this number for a coupling comes from:
is it related to pi or perhaps to the base of natural logarithms? Nobody knows.
It's one of the greatest damn mysteries of physics: a magic number that comes
to us with no understanding by man. You might say the "hand of God" wrote that
number, and "we don't know how He pushed his pencil." We know what kind of a
dance to do experimentally to measure this number very accurately, but we don't
know what kind of dance to do on the computer to make this number come out,
without putting it in secretly!

Length - Evolution from Measurement Standard to a Fundamental Constant

The modern length standard has evolved over a period of 200 years which has
brought it to a point where it can be continually improved without the
necessity of changing its definition. We may suspect that the developers of
the first length standard were as unprepared to predict present day developments
as we are to predict the advances that will be made in the next century.
Such developments will, no doubt, cause great excitement for those who make
precision measurements.

boleh tau apa saja soal dari usm itb dan berpa kali sih ujian seleksi
nya dan kapan sih bagian sumatera

Maksudnya paradox, barangkali, adalah sebuah fenomena yang belum
terjawab dengan pengetahuan yang ada atau kalau dilihat dari
pendekatan sisi tertentu saja. IMHO, karena saya cuma pemerhati
fisika.

Dalam matematika, ada paradox kuno yaitu Achiles paradox itu lho yang
kalau dipikir2 Achiles tidak akan pernah menyusul seekor kura-kura
dalam balap lari. Soalnya di setiap titik Achiles mencapai, si kura-
kura pasti sudah berlalu dari titik itu.

Lama sekali berabad-abad jawabannya tidak ketemu.  Bahkan paradox itu
jadi contoh kasus keterbatasan pemikiran teoretis terhadap kenyataan.
Setelah ada konsep limit, paradox itu terjawab sudah.

Salam,

bukanlah masalah kelemahan dalam ilmu Fisika, tapi ilmu Fisika itu
mengajarkan kita berpikir secara luas dan divergen dengan
mempertimbangkan segala peluang yang tidak atau mungkin.

assalamu'alaikum wr wb
maaf ni sebelumnya,karena tidak bisa sepenuhnya menjawab
pertanyaan saudara (belum sempat menghitung atau membuat
persamaannya). tapi setahu saya (kalu tidak salah ni..)
luas penampang plat berpengaruh pada nilai Q (muatan)
total, distibusi muatan homogen/tidak pada plat,seperti
pada hukum Gauss to?ya berarti berpengaruh juga terhadap
nilai medan listrik.
lalu buku yang mungkin bisa jadi referensi
"Electromagnetics Fields" karya Wangsness (saya lupa nama
depan dan tengahnya).ini mrpk buku diktat mata kuliah
"listrik magnet" saya.
sekian semoga bisa sedikit membantu...
wassalamu'alikum wr wb

yesi_fisika06_ugm

boleh tau apa saja soal dari usm itb dan berpa kali sih ujian seleksi
nya dan kapan sih bagian sumatera

Bukannya kita memiliki keterbatasan akal, sesuatu yang kita ketahui
dalam akal berpikir kita sebenarnyakan hanya sedikit. Paradox itu
adalh contoh dari ketebatasan akal kita. Paradox itu justru seperti
gunung es dari teori yang telah di bangun. Jadi paradox itu
menunjukkan ketidakkonsistenan dari teori yang telah di bangun. Dan
pada kenyataannya, paradox itu tidak bisa di eksperimenkan. bahkan
mustahil di wujudkan secara eksperimen.
So dengan adanya paradox berarti kita menjelaskan kelemahan dari teori
yang dibangun itu.
Mohon penjelasannya?

Assalam, wr,wb
semoga kesehatan dan kesejahteraan selalu menyertai kita
mau bertanya kepada semua rekan MFI:seperti kita ketahui besaran pokok
fisika adalah besaran yang satuannya telah ditetapkan terlebih dahulu.
atau besaran yang satuannya berdiri sendiri alias tidak tergantung
pada satu atau lebih dari besaran lain, terdiri dari 7 macam, salah

Ttg paradox kucing Schroedinger,no paradox there.The problem is the paradigm
used in seeing nature.Most things we know about nature are theories.The facts
are information we can get directly.Even electron is a theory,a very good
theory.

Definisi terkini meter, kilogram, detik,
dan-kawan-kawannya

Meter didefinisikan sebagai "panjang lintasan yang
ditempuh cahaya di dalam vakum selama selang waktu
1/(299 792 458) detik".

Jadi, meter sebagai satuan SI utk besaran-fisis
panjang TIDAK didefinisikan sebagai "laju per satuan
waktu", yang diambil-secara-lugu-dan-paksa dari
persamaan x=v/t.

Demikian pula dengan satuan ampere. Satuan ini
didefinisikan sebagai "Arus tetap, yang dipertahankan
untuk tetap mengalir pada dua batang penghantar
sejajar dengan panjang tak terhingga dan dengan luas
penampang yang dapat diabaikan dan terpisahkan sejauh
satu meter dalam vakum, yang akan menghasilkan gaya
antara kedua batang penghantar sebesar 2x10^(-7) N/m".

Jadi, ampere sebagai satuan SI utk besaran-fisis arus
listrik TIDAK didefinisikan sebagai "muatan per satuan
waktu", yang diambil-secara-lugu-dan-paksa dari
persamaan I=q/t.


Bila ingin mengetahui lebih mendalam ttg Besaran dan
Satuan, cobalah ke

Demikian jawaban singkat dari saya. Bila ada yg
keliru, silakan dikoreksi...

Salam,

Maxwell Demon Paradox: Selesai oleh Bennett dengan Information
Erasure-nya. (literatur tentang ini banyak banget: Coba lihat buku Le
Bellac, Gisin, atau Nielsen & Chuang ... dan buku-2 lain yang bicara
quantum computation and information)

Einstein Podolosky Rosen (EPR) "Paradox" ternyata tidak paradox:
Silahkan baca "Quantum Theory, Concepts and Methods" by Asher Peres
bab 6, dan EPR bisa di experiment-kan (see Aspect Experiment)

.. paradox yang lain-lain-nya? saya gak tahu status-nya, maklum cuma
dua di atas yang bersinggungan dengan wilayah kerja saya

:-)

PS: Jangan buru-buru menilai kalau yang terlihat seperti paradox itu
gak bisa di experiment kan ...

Assalam, wr,wb
semoga kesehatan dan kesejahteraan selalu menyertai kita
mau bertanya kepada semua rekan MFI:seperti kita ketahui besaran pokok
fisika adalah besaran yang satuannya telah ditetapkan terlebih dahulu.
atau besaran yang satuannya berdiri sendiri alias tidak tergantung
pada satu atau lebih dari besaran lain, terdiri dari 7 macam, salah
satunya adalah kuat arus listrik satuannya ampere, tapi kuat arus
listrik adalah banyaknya muatan per waktu, yang saya tanyakan:
1. bagaimana asalusul nya sehingga besaran pokok ada 7 macam
2. mengapa yang dimasukan besaran pokok tidak muatan (Q) dengan satuan
Coulumb, tapi malah kuat arus listrik yang satuannya diturunkan dari
besaran pokok waktu
terimakasih sebelumnya, kami mengharapkan jawabannya
wassalam

Hampir semua (kalau tidak semuanya) yang disebut paradoks itu terbagi
dua macam:

1) sesuatu yang berlawanan dengan intuisi/persepsi kita.  Twin paradox
termasuk tipe seperti ini.

2) sesuatu yang tidak dapat diuji secara eksperimen.  Kucing
Schrodinger termasuk tipe seperti ini.

Mari kita kembali ke dasar:

Fisika adalah ilmu yang mendeskripsikan alam secara kuantitatif.
Buang segala persepsi/intusi/akal sehat dan biarkan EKSPERIMEN yang
menentukan apakah suatu teori/konsep benar atau tidak.

Itu yang penting:  Prediksi teori yang dikonfirmasi eksperimen.

Physics is NOT a spectator activity.

Who cares about the twin paradox, general relativity has provided us
methods to accurately determine our position in space with GPS technology.

Who cares about Schrodinger's cat, quantum mechanics has provided us
many technological advances and breakthrough at such unimaginable level.

Please don't waste your time puzzling yourself about all sort of
paradoxes or philosophical debates.  Raise your sleeve, perform
calculations, do experiments, take measurements, analyze your data,
and see by your own eyes how physics can describe nature.  That's how
physicist DO physics.

Kalau lebih banyak fisikawan kita yang mau melakukan apa yang saya
sebut diatas dibandingkan ribut soal paradoks atau filosofi, fisika di
Indonesia akan jauh lebih maju.
