Thanks, mapman! I am back!! |
At least they are for me.

"When the laser beam is over a “land” the full reflected signal is registered by the photodetector for that short period of time."
Are you certain about that claim, professor? What if it is only 1/3 of the reflected signal? What happens to the remainder 2/3 of the reflected signal?

Hmmmm....April 1 was on Monday. Did somebody get a belated memo? |
So Geoff, Vanadium Dioxide nanoparticles in the thin plastic? |
Someone said on a blog that red visible and IR wavelength light could be absorbed by vanadium dioxide impregnated films. Exposed camera film might work, as claimed by some. |
Since blu-ray players use 405 nm lasers, lemon yellow should take out the invisible and visible light in that range.
|
Phytochromes have nearly perfect absorption characteristics for absorbing both Violet/UV and Red/IR bandwidths. The lambda max is substantially greater in the Red/IR region than that in the Violet/UV region. |
Well, some combination of yellow mixed with an organic compound that absorbs UV light bandwidths. There are plenty of organic dyes that absorb in that region (UV). I used to work with them in Advanced Photochemistry Research as an undergraduate. |
Reading comprehension is helpful; believing what one can Google is not helpful. Go look at a UV-Vis absorption spectrum for phytochromes. Then re-read my post.
|
As a guy having a Ph.D. in Biophysics from Harvard, I find it nice being marginalized by one who is not.
|
I never advise anyone on how to do their reporting. Something called a first amendment (to the extent moderated by the powers that be here) is in play..
|
Nope. It doesn't show the relevant region in the near and far UV.
|
Geoff, discussing NDM with you is..well..how can I say it? Interesting? |
Geoff, NDM is good...but not the panacea you claim. There will always be a better mouse trap, as your own empirical research-driven products demonstrate.
|
And I only bring up phytochromes for their unique special properties, not as a substitute for NDM. It’s the geek in me. Like MG, I couldn’t care less about the mechanism whereby NDM works. |
@glupson: have you tried NDM? |
It’s now clear to me that one must wake up pretty early to beat Geoff to posting here. |
Here is my room hit list for Friday morning at AXPONA 2019: 16-Aster: Shelter 384: Schiit 354: Fern & Roby 362: ATC/Lone Mountain Audio 442-444: Glenn Poor/Technics 452: Aesthetix 478: CPT A/V; Emerald Physics 552: Xact Audio 546: Linear Tube Audio 606: Linear Tube Audio 652: CAT 670: Benchmark Media Systems 696: Linear Tube Audio 1429: Sanders Sound Systems 1440: Durand Tonearms & Evolution Acoustics 1480: AGD Productions 8415: Linear Tube Audio 8470: Etymotic Research 9424: Mag-Lev Audio Hope to see some of you in the rooms!

I forgot one: 1010: Machina Dynamica
|
You might want to check. I don't think Room 101 has a bathroom.

I must have had too many cups of coffee today. I meant to say:
“Uber, the NICELY padded walls in that room are actually acoustic room treatments.”

☝🏻 Creepy stalker alert! 😂 |
If there is a worm in the bathtub, then you should ask for a different room.. |

Geoff classifies his jokes for my benefit. |
We can discuss cables here, if you want. In fact, I just affixed two NDM thingies to my DAC output IC’s going to my Teo Audio Liquid Pre passive preamp. Huge boost in inner detail and space from my ATC SCM20-2 active monitors..
I can’t wait to affix a few NDM thingies to my analog turntable platters.. |
If you attach a single NDM thingy to each ear lobe, then be prepared to be blown away with the improvement in SQ of your audio system.
|
Not if you’re one of the worms.. |
Somebody wake up Geoff. The men’s NCAA game is over. VA won. |
I disagree about the ease of leaving a Harvard program. Some graduate student in a Harvard Chinese History PhD graduate studies program could not find a “real world” job. So he simply stayed in graduate school as a teaching assistant. In that program for at least 23 years... |
I perceive no secret passwords, nor do I acknowledge that females cannot participate.

|
I was wondering how that penultimate post would be addressed to avoid becoming the death knell of this thread.
|
Why am I sensing a feedback loop here? |
Harvard Press? Humph..fake news |
|
As I said, I’m without words.. |
☝🏻 +1 for clarity, @glupson
This thread leads “recent activity” in the forum! |
This thread is quickly being pulled into a black hole..
|
As impossible as it might sound, this thread has made me less intelligent. |
Glupson, you are correct. Editorial accuracy matters. By all digital players, I think Geoff was attempting to capture all conventional CD, DVD, Blu-ray and related players. |

“>>>>That’s weird. I see some of my posts here dated as far back as 2002. Were those posts really mine and if so were they legal?”
I see that now. But A’gon must have discounted those earlier contributions. |
Anybody else tried NDM? Please chime in now before this thread loses all relevancy.. |
I may need to order a second NDM kit before the crush of new orders hits Geoff’s site. (And before the obligatory price increase hits the product.) |
Glupson, who made you A’gon scribe and editor?! “Come On, Man!” |
It’s the average Joe’s who decide Nobel prizes. |

@celander I’ve been no. 1 here for ten years. I kind doubt I’ll be going anywhere, ol buddy.

OMG, consider the ramifications of mapman’s suggestion:
Geoff sends NDM sample off to Stereophile for review —> Stereophile gives NDM a rave review —> Geoff slammed with NDM orders —> Geoff sets up his own NDM blog/vlog site to support the NDM sales —> Geoff never posts on the A’gon forums again. [Insert “My Pillow” commercial background music here..]
We will miss ya, ol’ buddy! 😥 |
