Thanks Again !

I have a stack of Wireless World magazines from the late 20s and early 30s that used to belong to my grandfather. I'm not sure if they are in good enough shape to scan but they really do need preserved before time takes its toll on the paper. Maybe set up a camera mount and photograph each page?

Better to use flatbed scanner

There's a great app for the iphone called CamScanner, which takes a photo of a page and then processes it. The result is typically almost indistinguishable from a high quality scan.

Unfortunately, it doesn't, especially if you zoom image. Better to use good flatbed and software with auto-adjustment of black/white levels (e.g. VueScan). Additionally, you will need to set up descreening at 125 lpi.

It would be a very great thing if they could be scanned and made available. Like other people, I think a flatbed scanner is the way to go.

This looks like an interesting article. Can you scan and post the rest of it?

Historical Physics Papers

 

[DF96]

Many of those articles are from the period in the 1980s when WW saw itself as an alternative physics magazine. Not mainstream science. Some might even turn out to be true, but that will come via the conventional route of peer reviewed proper papers not popular ramblings.

As a general rule anything about physics published in EW in that era is fruitcake stuff that nobody else woud publish. Ignore.

 

[Conrad Hoffman]

A flatbed is best, but can be slow. When I want decent quality but have no time I use a dSLR and shoot two pages at a time. Use a 100W (equiv) or larger 5500K compact florescent in a cheap metal reflector, one on each side of the magazine. I can go through a substantial magazine in very little time this way.

You are being too generous. I remember photocopying some of those and hanging them outside my office door. My students would read them, laugh hysterically, and then give me funny looks. My favorite was the fellow who tried showing that electrons didn't exist.

 

[astouffer]

Maybe when the weather cools down a bit and things get less busy I'll start scanning some. Hope the copyright police don't come after me

What do you think of this reference listed on this NASA website?
16. Muller,R.A., "The Cosmic Background Radiation and the new Aether Drift", In Scientific American, Vol. 238, N. 5, p. 64-74, (May 1978).

NASA - Warp Drive When - Annotated Bibliography

Are the people who write for Scientific American also sinners?

COBE took care of that.

claims the CMBR experiments prove there's such thing as an absolute velocity. One thing most knee jerk Einstein worshipers haven't considered is that Hubble's theory came after SRT. When SRT was first published, they believed in some sort of steady state universe.

Look, even Discover magazine has commited blasphemy!

Note mistake # 16 Mistake in the introduction of the cosmological constant (the “biggest blunder”)

 

[DF96]

I am not an astrophysicist, neither am I a "knee jerk Einstein worshiper", but I can't see anywhere in that COBE article where absolute velocity is claimed.

So Einstein made mistakes. Einstein was human. Humans make mistakes. And your point is?

Perhaps you are unable to distinguish between the process of science, advancing knowledge by correcting mistakes, and the blind following of gurus followed by toppling them off their perch when a new guru comes along (as favoured by the arts and politics).

No it doesn't. Did you bother to actually read it?
