another very famous example of the importance of resonance in history is the tacoma narrows bridge
http://en.wikipedia.org/wiki/Tacoma_Narrows_Bridge
when the bridge was built back in the 40s. when the wind goes up to certain level, it creates the exact right frequency of the bridge itself, causing the whole bridge to vibrate in a wave motion. and one day, the bridge finally collapsed. it was not due to especially strong wind (magnitude), it's due to the specific speed of the wind passing through the bridge (frequency). here's the video

For those of you on CL old enough (like me) to remember it, not only this LF-A commercial, but all of the similiar ones about glasses breaking under harmonic-vibration stress go back to the original "Is it live, or is it Memorex?" commercials of decades ago. The object, of course, was to prove that the high-quality Memorex tapes were so accurate they could recapture the voice of a professional opera singer and use it to shatter glasses the same way.

More about the science of the ad, they had a USC technical consultant:

Brilliant marketing....Brilliant.
I really like how it contrasts the old glass commerical on the LS engine.
Only issue I have is, Japanese cars often get labeled "Rice burners" for a reason.....shattering glass because it is really loud is cool....but going faster than the class is supposed to belong in is something that Lexus should be focusing on.
Brilliant marketing none-the-less

I am in love. I am going to have to own this master piece in my life time. I made up my mind. I don't care what people say about this car. My eyes kinda tear up everytime I look at these videos and feel funny in my tummy. If you call me a fan boy, so be it. I have no problem with that. Yes, I am that crazy about this car.

Just me, I like the LFA, but who thinks the engine whines more than roars? The "start up" sound that you can download from Lexus, it sounds as if some metal is rattling on startup. Did not sound particular "aggressive" on any of the sounds, accelerating or decelerating...
Then again, if you can go to 60 in less than 3.5s, who cares about the whining...

well, to back up a little bit, i can see how some people don't appreciate the sound. they like more of the deep roar muscle car sound, like from the amg. but if i have the choice, i would prefer f1 high rev high pitch sound any day. it just sounds so extreme and "into you" imho. well, i guess that's part of the reason why i love to redline my m3

Very true, and most people don't ever get to hear the sounds of exotics to appreciate the 'whine' vs 'roar' of an engine.

Quote: 1 SICKLEX
TORRANCE, Calif. (June 2, 2010)-It's a dramatic moment. In an ultra-modern audio studio, a Pearl White Lexus LFA supercar faces its challenger: a lone crystal champagne flute on a pedestal alongside a sleek amplifier. The vehicle's keyless ignition is engaged, and its rear wheels start spinning on a dynamometer. The engine roars louder and louder, the speedometer clicks past 150, 160, 170 mph. That's when the glass quivers and shimmies until – kshhh! – the flute shatters in gorgeous slow motion.
In this latest commercial from Lexus, which begins airing today, the LFA's signature engine sound achieves a feat reserved for virtuoso performers. The unique sound of 552-horsepower engine, which helps the vehicle reach top speeds in excess of 200 mph, shatters the glass without the use of CGI or camera tricks.
"The glass is actually broken by the precision sound of the vehicle," said Dave Nordstrom, vice president of marketing for Lexus. "We wanted to show just how deep our pursuit of perfection and commitment to innovation goes. The LFA was designed to deliver its own unique exhaust note, and this illustrates that beautifully."
The Signature Sound
Lexus worked with a team of engineers to enhance the acoustics of the LFA's 4.8L engine by meticulously tuning its multi-stage exhaust system. From the elegant, yet understated idle rumble to the goosebump-worthy wail of the high-revving V10 engine, the LFA was deliberately engineered to deliver a sound unlike that of any other road car.
After studying the unmistakable soundtrack generated by Formula 1 cars at maximum revs, the team created the signature LFA sound beginning by emphasizing the secondary combustion frequency of the engine and then introducing primary, secondary and tertiary firing harmonics.
The note is so unique that Lexus has even created an LFA ringtone that can be downloaded for free athttp://www.lexus-lfa.com (click "Digital Premium").
The Glass Test
For the commercial titled "Pitch," Lexus employed a renowned physicist from a leading university to help determine which type of champagne glasses have the same frequency as the LFA's revving engine. (The pitch of the glass needed to precisely match the pitch of the engine in order for the flute to shatter.) Lexus racecar driver Scott Pruett then "drove" on the dynamometer until the engine revved to 7,000-9,000 rpm-creating just the right frequency of vibration to break the glass. And, yes, the entire crew wore earplugs during filming.
It's not the first time Lexus has used champagne glasses in an ad. Now an almost iconic expression of the brand's pursuit of perfection and pioneering innovation, they were originally used in the brand's launch commercial in 1989. In one of the most memorable TV spots in history, the new LS sedan revved to high RPMs as a pyramid of champagne glasses was carefully stacked on the car's hood. As the speedometer approached top speeds, champagne was poured into the top glass and elegantly flowed into the glasses below-without spilling a drop or razing the pyramid.
Most recently, in a 2006 commercial, the ground-breaking park assist feature on the LS 460 was engaged to dramatically and precisely parallel park the vehicle between two giant pyramids of champagne glasses-without touching a glass.
"Pitch" can be viewed at YouTube.com/lexusvehicles. It will air primarily on cable television and during sporting events such as the 2010 Major League Baseball All-Star Game and the USGA U.S. Open Championship. A 3-D version of the spot will play in theaters beginning July 2 to coincide with the debut of a 3-D summer blockbuster.

the statements above seem to match what I said at the beginning of the thread before the trash talking started. We have people who dont understand physics as much as they favor Lexus . I never detracted from the LFA. All I did was to respond in that it looks cool but its not as difficult as you might think.
SO I obviously dont need a physics lesson from anyone on this forum. Some of you guys may need to brush up resonance and amplitude wave energy facts. Seems like we don't retain info as much as we like to discredit others.
Again thanks for the laugh.
PS My buddy ,who teaches at Harvard med school ,and I just has a laugh reading these responses. Thanks again for the laugh

I8ABMR,
Everyone in this thread was responding to your initial statements saying that the glass breakage was caused by an amplified sound vs resonance. You said
However I have asked for folks to knock off the personal comments and your posts / edited / re-edited posts above clearly attempt to continue earlier arguments that we need to end now. I'm going to ask you to exit this thread please.
