Analogija-razno

OdgovorNapisal/-a kuzma2 » To Mar 21, 2006 7:54 pm

Michael Fremer,
Cornell ‘69, Senior
Contributing Editor
to Stereophile. As
a Cornell alumnus
we will roll out the
Big Red Carpet.
Michael was a DJ
here on WVBRAM
until he was shown the door in 1965 for
being Howard Stern before Howard Stern. He
returned to the radio in Boston in 1973 on
the legendary “* form” rock station WBCNFM
until he was fired there too, for the same
reason. He went on to stand-up comedy and
later co-wrote and voiced an animated film
“Animalympics,” with Gilda Radner, Billy
Crystal and Harry Shearer. Later he supervised
the Academy Award nominated soundtrack to
the sci-fi feature film “Tron.”
The introduction of the compact disc so upset
him that he dropped everything to campaign
against it. Thus began a twenty plus year
writing career. In addition to writing for
Stereophile, Fremer has written for The New
York Times, The San Francisco Chronicle, and
many other magazines and newspapers.
He can be found online at www.ultimateavmag.
com where he has a blog and writes A/V
reviews and on his own music review website
www.musicangle.com.
Michael will speak about his obsession
with vinyl long playing records and explain
why it is currently making a comeback,
especially among young musicians who
insist on releasing their music on vinyl
and among an “enlightened” segment
of college students. He promises to be
funny and outrageous but not to the point
of being shown the door at Cornell again.
LIVING ANALOG THE RETURN OF VINYL RECORDS IN THE IPOD AGE

Michael Fremer, Cornell ‘69
Senior Contributing Editor to Stereophile
Sponsored by the Carl Becker House and the Office of the Dean of Students.

Kaj mislijo najstniki o vinilu:


SOURCE: http://www.physorg.com/news64807495.html

VIA: http://www.digg.com/technology/Teens_co ... ior_to_CDs

"A Canadian scientist says teens who used to view CDs as superior to
older vinyl records now consider vinyl superior to the newer format.

David Hayes of the Ontario Institute for Studies in Education at the
University of Toronto says the growing popularity of vinyl might be a
form of resistance against the music industry's corporate taste-makers.

While conducting research for his Ph.D. dissertation, Hayes was
surprised to discover the young music enthusiasts he was interviewing
were fans of vinyl.

"This made me wonder why they were interested in something that is, for
all intents and purposes, a dead medium," he said, noting the teenagers
had switched from buying CDs to collecting LPs, often seeking obscure
recordings.

Hayes research subjects said they liked the visual appeal of LP jackets
and the challenge of seeking hard-to-find releases.

In yet another turnaround, teens overwhelmingly insisted the sound
quality of LPs was superior to that of modern formats. They
characterized LPs and the LP artists of the past as more authentic than
the barrage of youth-oriented music being aggressively marketed to them
today."

Hayes detailed his research in the February issue of Popular Music and
Society.

AW test Kuzma StabiS/StogiS

OdgovorNapisal/-a ak » Sr Maj 03, 2006 11:42 am

Živijo,

med branjem članka v AW (link iz Kuzminih novosti) sem opazil...

"Brass magnet spindle weight is $99.00"....Brass magnet spindle...brass magnet...magnet....

A je to kak "upgrade" uteži, da je not udelan magnet? Ker pri mojem clampu nisem še nikoli čutil kakega magnetnega delovanja.

Hmmm...krožnik je pa iz česa? Moral bi biti iz materiala, ki vsebuje kar precej železa, da bi magnet prijel, še posebno na razdalji, ki jo povzorča tisti črni dušilni material in plošča....če je krožnik Alu, potem magnet itak nima tam kaj dosti iskat...

Noja, morda gre pa za tipkarko napačo... 8)

Umetniki včasih po svoje razumejo in si razložijo fiziko.Tekst ,ki opisuje neke stvari ni ravno najbolj natančen.

Hvala , jih bom opozoril!

PS: Sicer je pa gravitacija tudi neke vrste magnetno polje, a ne?

Ups, to pa ne :shock: ...gravitacija je gravitacija (in jo povzroča masa objektov), magnetno polje je pa magnetno polje in ima bolj malo veze z maso ali gravitacijo.

Je pa verjetno res, da ima clamp enak učinek če je zadosti težak, ali pa če je magneten (samo da bi tak potreboval fero-magneten material na krožniku).

No, tukaj se lahko uporabi poleg klasične Newtonove teorije še marsikaj drugega, ampak tukaj ni mesto za to. Seveda sem bolj mislil, da je efekt privlačnih sil podoben in ne nastanek.

Efekt gravitacije je poznan, tako kot samega magnetizma, samih vzrokov pa še ni čisto razloženo in tukaj pride v poštev mogoče Einsteinova teorija, ki tudi zajema vpliv enega masnega polja na drugega, kjer pa seveda masa kot taka lahko izgine ob gibanju a sile še vedno ostanejo, ki se privlačijo.Kaj se zgodi z gravitacijo, ko masa potuje s svetlobno hitrostjo,....

Malce bolj za hec:

Skratka, mogoče se ob vrtenju clampa zaradi magnetnega polja motorja inducira neka napetost v clampu, ki povzroči magnetno polje, ki inducira napetost v T deli subšasije, ki zopet povzroči sile, ki lahko malce privdignejo clamp ali ga pritegnejo zaradi nasprotnih sil magnetih polj.

No , ampak ker gramofon deluje po klasični fiziki pustimo to in vsekakor imam rad čim manj zunanjih magnetnih polj okrog odjemne doze.

Evo na American Wired je že popravljeno- seveda je sedaj clamp postal le "weight" brez "magnetic". Hvala za pomoč.

Zaradi vrtenja rotorja se v klampu ne more inucirati nič, ker se tudi klamp vrti (oziroma čisto malo zaostaja za vrtenjem magnetnega polja-slip)
Skratka, naredilo so napako in jo tudi že popravili, ostalo so zgolj bajke.

vrtenje klampa seka silnice motorja, katere se ne vrtijo z klampom, ampak okrog ohišja motorja.....

No dajmo to debato raje nadaljevati pod avdio ne"resnostmi".

Michael Fremer je izdal DVD, kjer prikazuje nastavitve gramofona, ročic in odjemnih doz. Za začetnike in tiste, ki bi se radi naučili nekaj več, si preberite kaj je napisano o tem v Positive Feedback:
