Again, if you think this is antigravity, then so is a hot air balloon.

(Hmm... if you coated the inside surface with a light, airtight polymer, could even a muumuu be converted into a viable antigravity system then?!)

You mean Bat Boy (or whatever) really couldn't fly like he did in the X-Men prequel?

Bummer. LOL

Yes, MM, this is well known. But sound can only move very very tiny and light objects. AND it has to be REALLY LOUD. And you need reflectors (like in a box) and a pure single frequency tone to reflect the sound wave to make a standing wave.

"Has anyone read this?"

Like you're really considering doing so?! LOL

You just want someone to summarize/condense it for you so you don't have to bother.

Lazy, lazy, lazy.

"Hacking Matter: Levitating Chairs, Quantum Mirages, and the Infinite Weirdness of Programmable Atoms?"

It's serious science speculation. You wouldn't like it.

Always time for Monty Python. :)

Supposedly the latter.

Marilyn claims that she wants to update and inform the science fiction crowd (both readers and authors) concerning science news. Because, I guess, she thinks we don't or won't follow such news on our own anyway. So she has several science threads ongoing here in SF.

I really think it's all because she knows the people over in the Science forum would soon rip her to shreds if she posted this kind of crap over there.

Or worse... ignore her completely.

Concerning Spam...

>>>> cue Monty Python

and now for clarification ... is this thread topic supposed to be taken seriously?
Or is it a scientific discussion being held on an Amazon SF forum page?

Lol Ronald thanks for understanding.

Not to worry, Marsheena. This whole thread concerns a (fundamental misunderstanding of a) scientific topic, so it's presence in this, the science fiction forum, constitutes spam of a sort. LOL

Posted on Dec 25, 2012, 3:03:04 PM PST
sorry about the spam.

she is spamming.

RE: "He's my best friend: Book 1- Young Love"

What does this have to do with the topic - or anything else, for that matter?

Nothing beats a reliable, and fashionably Persian, flying carpet

*** Suggestion when cleaning your flying carpet ... never hand beat it like a common floor rug... ... I recommend investing in a high end carpet steaming system... much like a Bissell, Hoover or a Stanley Steamer..

Where's my hot-air balloon? ;)

Sigh. This only deals with moving electrons through materials. It says 'effective mass' because they think they can move the electrons more quickly using the right material. Accelerating an electron faster MAKES IT SEEM as if it has lower mass. It doesn't really have lower mass. That's what 'effective' means. They are making it REACT faster than it normally would.

It has implications for faster switches and circuits, and (though the article does NOT say the following, and here is a true speculative statement), perhaps it may help someday to create high temperature superconductors.

It as NOTHING to do with gravity. Zippo. Not even remotely.

Ronald Craig says:
"No relation to anti-gravity (yet)"

Or ever. Magnetism is not antigravity. You still don't get it, do you?

"THIS may be closer to anti-gravity ..."

No. It's about reducing the *effective mass* of electrons to zero. It has to do with semiconductors and "may pave the way for faster electronic devices and detectors and functional materials with a strong electrical response in the infrared regime."

Nothing at all about antigravity. (So what if you have zero-effective-mass electrons? What about the mass of the protons and neutrons in the atoms composing the object you want to have floating about using your antigravity? D'uh. Think!)

"MAGNONICS" IS AN EXTENSION OF SPINTRONICS AND RELATED TO HELIX MAGNETISM
No relation to anti-gravity (yet), but still an interesting discovery.

http://nextbigfuture.com/2012/12/metamaterials-can-reduce-electrons.html
METAMATERIALS CAN REDUCE ELECTRONS' EFFECTIVE MASS TO NEARLY ZERO
"... materials to manipulate electromagnetic waves and fields in previously impossible ways." THIS may be closer to anti-gravity ...

Exactly. My post on p. 13, from November 2009:

"Magnetic levitation is only anti-gravity in the same way that Balloon Boy's flying saucer was."

(Refers to that hoax about the kid floating away in that homemade balloon.)

20 forum pages and three years on and I'd put good money on Marilyn still not understanding this basic distinction. Oh well.

Granted, my physics is more than rusty,but aren't they different forces? Isn't gravity related to mass and magnetics has to do with the quantum property of magnetic materials? I mean, it strikes me as tantamount to saying air pressure is anti gravity because planes fly.

It is now. Thanks.

Yes, one guy from the army claimed to have been posted to guard a flying saucer as it rested on the ground then said that it flew off at impossible acceleration. real science fiction there.
