at my judo class i get to touch women's boobies and have them straddling me and their ass in my face
all for free too
all for free too
I just woke up.I had a dream where I was outside a dilapidated church.Seems like it was in mexico or something because it was a white stucco building and rounded architecture.
Anyway ...all the windows were broken and I could see inside.
All I could see was snakes...Tons sand tons of snakes ...so many that they were floating on top of each other.Slithering in and out of the windows and doors...
Some of them were huge like trees but there was also small ones.
I could see at the top of the building a small window that had flames coming from it and the flames were growing.
So I decided that someone must have set the church on fire.
I watched the fire spread for a while but then I took off.

I touch women's breasts all the time when doing echocardiograms, its just tissue, I dont see the big deal, of course Im in a wholly professional mindset when I do them.

I had a dream a lil while ago that I made a thread on EF about now that spring is here that its time for slurpies from 7-11 and discussing the various flavors. Dont know what freud would say about that, I had some other interesting thread topics that I dreamed about but I cant remember them.

There was a recent paper claiming to demonstrate the indivisibility of
photons in a beam splitter experiment (the remote "wave collapse"
upon "measurement" of "photon" in one of the detectors).
1. J.J. Thorn, M.S. Neel, V.W. Donato, G.S. Bergreen, R.E. Davies, M. Beck
"Observing the quantum behavior of light in an undergraduate laboratory"
Am. J. Phys., Vol. 72, No. 9, 1210-1219 (2004).
Experiment Home Page
The authors claim to violate "classicality" by 377 standard deviations,
which is by far the largest violation ever for this type of experiment.
The setup is an archetype of quantum mystery: A single photon arrives at
a 50:50 beam splitter. One could verify that the two photon wave packet
branches (after the beam splitter) interfere nearly perfectly, yet if
one places a photodetector in each path, only one of the two detectors
will trigger in each try. As Feynman put it - "In reality, it contains
the only mystery." How does "it" do it? The answer is -- "it" doesn't
do "it" and the mysterious appearance is no more than a magic trick.
Unlike the earlier well known variants of this experiment ([2],[3]),
the present one describes the setup in sufficient detail that the
sleight of hand can be spotted. The setup is sketched below, but
you should get the paper since I will refer to figure and formula
numbers there.
Code:
G photon Source TR photon PBS T
DG <---------- [PDC] ----------------\----------> DT
|
| R
V
DRThe PDC Source generates two photons, G and TR. The G photon is used
as a "gate" photon, meaning that the trigger of its detector DG defines
the time windows (of 2.5ns centered around the DG trigger) in which
to count the events on the detectors DT and DG, which detect the
photons in the Transmitted and Reflected beams (wave packets). The
"quantum" effect they wish to show is that after a detector, say,
DT triggers, the other detector DR will not trigger. That would
demonstrate the "indivisibility" of the photon and a "collapse"
of the remote wave packet at DR location as soon as the photon
was "found" at the location DT.
In order to quantify the violation of classicality, [1] defines
a coefficient g2 which is a normalized probability of joint
trigger of DT and DR (within the windows defined by DG trigger)
and is given via:
.... g2 = P(GTR) / [P(GT)*P(GR)] ... (1)
or in terms of the (ideal) counts as:
.... g2 = N(GTR)*N(G) / [N(GT)*N(GR)] ... (2)
where the N(GTR) is count of triple trigger, the N(GT) of double
triggers DG and DT, etc. The classical prediction is that g2>=1
(the equality g2=1 would hold for a perfectly steady laser source,
the "coherent light"). This inequality is eq (AJP.3). The quantum
"prediction" (eq AJP.8,13) is that for a single photon state TR,
the g2=0. The paper claims they obtained g2=0.0177 +/- 0.0026.
The accidental (background) coincidences alone would yield
g2a=0.0164, so that the g2-g2a is just 0.0013, well within the
std deviation 0.0026 from the quantum prediction. Perfection.
The two tiny, little clouds in this paradise of experimental
and theoretical perfection are:
a) while there is a QED prediction of g2=0, it is not for this
kind of detection setup (that's a separate story which we could
pursue later), and
b) the experiment doesn't show that (2) yields g2=0, since they
didn't measure at all the actual triple coincidence N(GTR) but
just a small part of it.
Let's see what was the sleight of hand in (b). We can look at the
coincident detections scheme as sampling of the EM fields T and R
where the sampling time windows are defined by the triggers of
gate DG. Here we had sampling window of 2.5ns and they measured
around 100,000 counts/sec on DG (and 8000 c/s on DT+DR). Thus
the sampled EM field represents just 0.25 ms out of each second.
The classical prediction g2>=1 applies for either continuous or
sampled measurements, provided the samples of GT and GR are
taken from the same position in the EM stream. For the coincidences
GT and GR, [1] does seem to select the properly matching sampling
windows since they tuned the GT and GR coincidence units (TAC/SCA,
see AJP p.1215-1216, sect C, Fig 5) to maximize each rate (they
don't give unfortunately any actual counts used for computing via
(2) their final results in AJP, Table I, but we'll grant them this).
Now, one would expect, that obtaining the sequence of properly
aligned GT and GR samples (say a sequence of length N(G) of
0's and 1's), one would extract the triple coincidence count
N(GTR) by simply adding 1 to N(GTR), whenever both GT and
GR contain 1 for the same position in the bit array.
But no, that's not what [1] does. For "mysterious" reasons
they add a third, separate coincidence unit (AJP.Fig 5; GTR)
which they tune on its own to extract its own separate sample
of EM fields. That alone is a gigantic loophole, a secret pocket
in the magicians sleeve. If the sampling windows GT and GR for
the new GTR unit are different enough from the earlier GT/GR
windows (e.g. shifted by just 1.25 ns in opposite directions),
the classical prediction via (2) will also be g2=0 (just background).
And as they're about to finish they pause at the door, with
'and by the way' look say "There is one last trick used in setting
up this threefold coincidence unit." where they explain how they
switch optical fibers, from DR to DG, then tune to G+T to stand
in for R+T coincidences, because they say "we expect an absence
of coincidences between T and R" (p 1216). Well, funny they
should mention it, since after all this, somehow, I am also
beginning to expect the absence of any GTR coincidences.
Also, unlike the GT and GR units which operated in START/STOP
TAC mode the GTR unit operated in START GATE mode, where a
separate pulse from DG is required to enable the acceptance
of DT and DR signals (here the DT was used as START and DR as
STOP input to TAC/SCA, see fig 5, while in the other two units
G was used for SATRT and T or R for STOP). It surely is getting
curioser and curioser, all these seeming redundancies with all
their little differences.
The experiment [3] also had a 3rd GTR unit with its own tuning,
but they didn't give any details at all. The AJP authors [1] give
only the qualitative sketch, but no figures on the T and R sampling
window positions for GTR unit (e.g. relative to those from GT and
GR units) were available from the chief author. Since the classical
prediction is sensitive to the sampling window positions, and can
easily produce via (2) anything from g2=0 to g2>1, just by changing
the GTR windows, this is a critical bit of data the experimenters
should provide, at least mention how they checked it and what
the windows were.
Of course, after that section, I was about ready to drop it
as yet another phony 'quantum magic show'. Then I noticed
at the end they give part numbers for their TAC/SCA units,
(p1218, Appendix C): ORTEC TAC/SCA 567. The data sheet for
the model 567 lists the required delay of 10ns for the START
(which was here DT signal, see AJP.Fig 5) from the START GATE
signal (which was here DG signal) in order for START to get
accepted. But the AJP.Fig 5, and the several places in the
text give their delay line between DG and DT as 6 ns. That
means when DG triggers at t0, 6ns later (+/- 1.25ns) the
DT will trigger (if at all), but the TAC will ignore it
since it won't be ready yet, and for another 4ns. Then,
at t0+10ns the TAC is finally enabled, but without START
no event will be registered. The "GTR" coincidence rate
will be close to accidental background (slightly above
since if the real T doesn't trip DT and the subsequent
background DT hits at t0+10, then the DG trigger, which
is now more likely than background, at t0+12ns will
allow the registration). And that is exactly the g2 they
claim (other papers claim much smaller violations and
only on subtracted data, not the raw data, which is how
it should be, the "nonclassicality" as the Quantum Otpics
term of art, not anything nonclassical for real).
So, as described in [1], the GTR unit settings will cut off
almost all genuine GTR coincidences, yielding the "perfect"
g2. I did ask the chief experimenter about the 10ns delay
and the inconsistency. Oh, he knew it all along, and they have
actually used the proper delay (and not the 6ns as stated the
paper), but the paper was too long for such details. Lemme see,
they wrote the paper and the AJP told them to shorten it to such
and such length. Now, say, the six of them sweated for a day
editing the text, and just had it at about the right length,
except for 5 extra characters. Now, having cut out all they could
think of, they sit at the table wondering, vot to do? Then suddenly
a lightening strikes and they notice that if they were to replace
the delay they actually used (say 15ns, or anything above 11.5,
thus 2+ digit anyway) with 6 ns they could shorten the text by
10 characters. Great, let's do it, and so they edit the paper,
replacing the "real" delay of say 15ns with the fake delay of 6ns.
Yep, that's how the real delay which was actually and truly greater
than 10ns must have become the 6ns reported in the paper in 10 places.
Very plausible - it was the paper length that did it.
And my correspondent ended his reply with: "If I say I measured
triple coincidences (or lack thereof) then I did. Period. End of
discussion." Yes, Sir. Jahwol, Herr Professor.

Cool Samoth, I have to read it later and work it out in my head. I need to slow down when Im reading technical stuff like that. Takes me a long time to digest something like that.
You know you should start a thread in mindbodyspirit with more articles like this that you think would be a good read for someone at lower levels like myself, physics for dummies you could call it LOL
Itll give me something to do when the board gets real slow, entertain me!!!!

Okay. "I've been alive forever and I wrote the very first song. I put the words and the melodies together, I am music and I write the songs. I write the songs that make the whole world sing, I write the songs of love and special things. I write the songs that make the young girls cry, I write the songs, I write the songs." Now I feel better.

Here's a guy you want teaching your kids. Dr. Thomas Perls, the director of the New England Centenarian Study at Boston University Medical School, told a conference in Brisbane, Australia, that he donates blood regularly because one of the key reasons why females outlive males is menstruation adding that iron loss inhibits the growth of free radicals that age cells. Dr. Tom also said, "I menstruate -- but only every eight weeks." (News Limited)

Once upon a time, there was an island where all the feelings and sentiments lived; Happiness, Sadness, Knowledge and all the others, including Love.
One day, it was announced to all of the feelings that the island was going to sink to the bottom of the ocean. So, all the feelings prepared their boats to leave. Love was the only one that stayed to the end. She wanted to cherish the island paradise until the last possible moment.
When the island was almost totally under, Love decided it was time to leave. She began looking for someone to ask for help. Just then, Richness was passing by in a grand boat. Love asked, "Richness, Can I come with you on your boat?" Richness answered, "I'm sorry but there is a lot of silver and gold on my boat and there would be no room for you anywhere."
Then, Love decided to ask Vanity for help, who was passing in a beautiful vessel. Love cried out, "Vanity, help me please."
"I can't help you," Vanity said, "You are all wet and will damage my beautiful boat."
Next, Love saw Sadness passing by. Love said, "Sadness, please let me go with you."
Sadness answered, "Love, I'm sorry but I just need to be alone now." Then, Love saw Happiness. Love cried out, "Happiness, please take me with you."
But, Happiness was so overjoyed, that he didn't hear Love calling to him. Love began to cry.
She then heard a voice say, "Come, Love, I will take you with me." It was an elder. Love felt so blessed and overjoyed that she forgot to ask the elder his name. When they arrived on land, the elder went on his way. Love realized how much she owed the elder. Love looked for Knowledge and asked, "Who was the elder that helped me?"
"It was Time," Knowledge answered. Love asked, "But, why did Time help me, when no one else would?".
Knowledge smiled and answered, "Because only Time is capable of understanding how great Love is."

one time i was walking in on the land. I could smell all the wonderful smells!!! then a swarm of bees came swarming at me. I freaked out "i think those fucking things that buzzzzzzzz" are scarry..... so i just got an adrenilen rush. I said AAAAA shit ... and ran. until they caught me. I was like oh no, fuck help me Yea! I yelled that out loud.. And all of the sudden this guy said what the fuck is wrong with you?? and i opend my eyes .I guess i had been night night and siad some stuff out load....and i was setting next to my cell phone that was set on vibrate. it was setting next to me buzzing.. "I guess it sounded like bees , I realized I had fell asleep.. I looked around and everyone was staring at me. because i was a sleep yelling all the shit like oh fuck aahh and stuff.... So i freaked out and got up so fast than I Knocked the offering plate on the ground and farted.
and all the old people got up and said halaluya!! but when i did it. i wet myslef and had to go home and change.. .... he ha he ha heee hawww i said as i ran out of the chruch..!!!

The word is used in chem and historical physics. In physics, the ether was the 'stuff' all around us that allowed propagation of electromagnetic waves (light), before science realized that it does not need a medium to propagate. The term became obsolete around the 1920's or so, near the birth of quantum mechanics and general relativity, with the famous Michaelson-Morley experiment (involving mirrors and timing light and stuff).
In chem, ether is two alkyl groups connected by an oxygen. And it smells funny. It's usually used as a solvent at the university orgo-level.
