Nice. Thank goodness the animator didn't start right from the very beginning of the photon's life, as it takes around 170,000 years for a photon to travel from the core to the Sun's surface.

My favorite remains:

A photon walks into a hotel and checks in. "Do you want a hand with your luggage?" asks the receptionist. "No thanks", replies the photon, "I'm travelling light".

Lasers have a pretty amazing attribute where you can use a wavelength that is only absorbed by certain materials, leaving all other materials entirely untouched by the photons (as they have a very high reflectivity or transmission index for the wavelength).

No idea whats going on with this system, but its possible they are using a colour that is optimised for maximal paint absorption (heats up the paint the most), whilst at the same time maximal metal reflection (doesnt transfer any energy into the metal).

Source: telecom engineer (I work with lasers...)

Neat. Does the entire system *draw* 1kw, or does the beam actually deliver 1kw (seems unlikely)? Either way, it must require massive off-camera cooling equipment. I've seen arrays of LEDs used for welding before and that was impressive.

It must be a prototype because the company that makes it doesn't list this model, and don't give much information on the models they do list. And, of course, it doesn't look remotely practical, awesome as it is.

edit:

After a bit more reading, maybe it does emit 1000 watts. Also, look at this thing from their webpage:

http://www.nortonsandblasting.com/images/lasr-backpack_unit1web.jpg

That is a straight up proton accelerator if I've ever seen one (okay, maybe photons, but close enough) and I damn well want one. I promise to use it responsibly and never cross the streams.

I think color could be achieved by having the ionization at a different frequency so it produces photons on a colored wavelength.

What I want to know is:
1) does it fry the flesh from your skeleton if you stick your hand in the middle?
and
2) how long until we can get lightsabers?

I'm in total agreement with @MichaelL. Strictly speaking, this is definitely not an optical illusion by virtue of the fact that it is not an illusion.

You're just seeing objective reality the way nature is presenting it to the universe and the same way everyone else sees it. It would only be an optical illusion if it physically existed one way but your eyes/brain perceived it a different way.


It'd be like turning on a light in a dark room and declaring it an optical illusion that everything is illuminated because the photons from the light source are making everything look bright, but in reality it's all dark, so: optical illusion. "The room is being incorrectly perceived because it's actually dark, but you're perceiving it as bright."

Yeah, no.

Interesting talk that I enjoyed a great deal, though I wonder if that was more for the quality of his delivery rather than the material.
It was interesting to learn about reality being wave-based and our perception is that of the particle. e.g the EM wave that is light we see as particles we call photons.
Also I do believe Dawkins was there at the end asking a question.

Have a friend who made a few jaw-dropping star trek fight space scenes, complete with custom ships, phasers and photon torpedoes striking shields and cutting/ripping through hulls. All done in paint. I could not believe it. To this day I can't imagine how he did it. Of course he was a teen with perfect vision, so props to this guy too!

Suns rays hitting us are 30,000 years old??? It's actually only 8 minutes.

EDIT: some google searches are saying the 30K is including the time it takes for a photon to LEAVE the sun...uhm..OK I guess

EDIT2: oops, was commenting to a different video that was displayed after this video. my bad...and it's too late for me to delete this, oh well..might as well share what video I was commenting to: http://youtu.be/lLoQftUMPmY

> block the signal unless 5 to 9 photons arrive within less than 100 ms

This is true. My own system (as new) was 8 photons at 80ms. I installed the tweaking kit from NewEye and have been running around set to 3 photons and 200ms lately and.. it's a trip. Anything beyond the Selsky border of 3 photons and 150ms will show you aura (around healthy people anyway) so I am seeing aura almost every time at 3/200. I have to scale back when driving.

The SIGINT side of this all is still completely overlooked. You can copy every bit coming from fibers without anyone noticing it in either end. Hell, you can't see it happening between two closest nodes... All you see is a slight drop in the signal levels as few photons are separated from the original stream and then amplified before it's sent thru the same network as regular traffic.

> soon to be replaced by 3D printed lost wax casting

In 2026, the first molten metal inkjet with > 500 dpi spatial resolution is created. Metals are transported as tiny balls and then fused with high power photonics. No matter what is created, it ends up as a single crystal of metal.

There are no absolute logical principles <---- including that one. This is simply another way of describing the problem of induction and under determination. Like so many philosophical arguments you have attacked my position based upon the language it was described in and not due to its underlying thought process. This has resulted in a fallacy. Language merely conveys knowledge, it does not in an of itself contain it (and excellent example incidentally of what I was talking about).

Your argument eats itself. If there aren't any absolute laws of logic (including that one), then there are no rules period, and thus no logic. If there is no such thing as logic then I could say "The cucumber faints west in the umbrage" and it would be an entirely valid response to anything you say. Yet you continue to make absolute statements like:

"All principles (save the observation "thinking exists") can only ever derived by induction."

"This is the case because one can never know for certain if any or all of ones experiences are fabrications"

"you can't ever be certain about any judgement one makes about the universe or anything in it because one cannot observe an exhaustive perspective"

The sea cucumber faints west in the umbrage, my friend.

All principles (save the observation "thinking exists") can only ever derived by induction. This is the case because one can never know for certain if any or all of ones experiences are fabrications, and furthermore that they never encompass all possible variables/possibilities. To put it another way, you can't ever be certain about any judgement one makes about the universe or anything in it because one cannot observe an exhaustive perspective (i.e. all of time and space for the thing in question). Thus there may always exist an example that could falsify your assumption. e.g. if I inducted that all swans are white because I had only ever seen white swans I would ultimately be incorrect as black swans can be observed to exist. Unless you can verify the entirety of existence across time there might always exist and experience/example to falsify any objective assertion. (you could be a brain in a jar, you can't prove 100% that your not)

No, I can't 100 percent prove I am not actually a circus peanut dreaming I'm a man, but it doesn't matter what I can prove to you. What matters is what is true. You have absolute freedom to live in total denial of reality if you want to, but reality isn't what we dictate it is. Just because you have no way of figuring it out doesn't mean no one does. The one who does have it figured out is God, because He created it. Because He is God He can make us absolutely certain of who He is and what He wants from us, transcending all physical or mental rationale.

^ Pardon me? Did you even read what I wrote by way of explanation for that? What part of "everything is permitted" even remotely precludes me (or anyone) from anything, let alone arguing against Christianity?!?!?

If everything is permitted then it is equally valid not to permit, which means you have no argument. Your way isn't better than any other way according to your logic so all that you can argue is that you prefer it.

What I felt I'd explained fairly clearly was the idea that the only demonstrable moral authority was yourself, or to put it another way that there are no moral authorities to be found anywhere else but within peoples minds.
Even if God himself speaks to you directly, that is an experience reducible only to the mind because ALL EXPERIENCES WITHIN HUMAN CONCEPTION OCCUR IN or at best VIA THE MIND!

I can't prove God exists to you, but He can. God isn't hiding from you; He has been knocking on your door your entire life. It's your choice whether you want to open the door, but you are going to meet Him one day regardless of what you choose.

Nothing has ever happened to any human being anywhere that was not experienced entirely in the mind (notice I didn't say "brain" ). When you see a chair you don't see the photons of light hitting your retina, you see something your mind made up to be representative (at best) of whatever phenomenon your eyes detected.

With that in mind (<- mind lol), "everything is permitted". The universe will continue on, unmoved by our moralities (or lack of). Only other humans will cry or rejoice at your actions and only within the sovereignty of your own mind will you find an irrefutable and absolute moral judge...

I was created before I had a mind. The Universe has a beginning, it was created, and the Creator is the judge.

Apart from all the same major dates for festivals and holy days (25th dec etc.),

The Catholics borrowed those from the Pagans..you won't find those in the bible.

the entire symbology of dieing on a cross for three days then being resurrected, the "last supper" with 12 disciples, 3 wise men from the east bearing gifts. etc. etc.

Sources?

I'd have more time for the Christian counter argument that the Mithraists stole this stuff from them if the same themes, dates and symoblogy didn't pop up in ancient cultures going back a few 1000 years over and over and over. The list of Messianic figures with the above characteristics in western folklore & myth is so long its almost a joke! & naturally is no co-incidence as they are describing the movement of the heavens (specifically the sun) by way of allegory. Speaking of which..

Let's see some sources..

But then the Catholic Church did it level best to suppress and destroy any trace of Gnosticism through the ages so its no surprise to me that you're not entirely familiar with it. (most people haven't even heard of it and those that do tend to be under the misapprehension that its a Christian thing (again understandable under the circumstances))

I know exactly what it is and I am very familar with it.

I'll come with you a little on that one. Before Rex Mundi (Jehova) showed up to fk everything up for them the Kabbalistic (and essentially Pagan) Jews possessed great wisdom and insight. Naturally not all of this was lost! (though after Solomon passed it would appear a regrettably large amount was)

Abraham is the father of the Jewish people and he worshiped the LORD.

I'm not sure I even want to grace that with a response. How could you possibly know what came from the mouth of God to a man 2000 years ago? If you say "because it says in the bible" please don't expect a sensible reply (I'm happy to fight non-sense with none-sense)

Because I know Him personally and His Spirit lives within me.

^This one amused be greatly. I would say Buddhism & Zoroastranism were clearly superior for exactly that reason but that's not what I think you were alluding to? I assume you were suggesting that certain parts of the whole Jesus shebang could only have come from Jesus/God/Holy spirit because he made himself the centre of attention?

To be a Christian is to have a personal relationship with Jesus Christ. Therefore there is no Christianity without Him. He is the only way to know God:

John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

He wasn't pointing to Himself, He was pointing to God.

This is why I make a very distinct separation between the "Jesus" and the "Christ". Christ (or anointed one) goes back at least to Egypt. Horus is clearly "Christ" by basically any sensible measure I can think of, and by "Christ" I mean the "Sun of God" i.e. the freaking Sun.

This also forms the basis for an "as above so below" parable/allegory for the spiritual journey to enlightenment. You can find your way to heaven and God via the "Sun of God's" wisdom. No Miracle performing hippie Jew's were required before and I fail to see how sprouting the same fundamental idea just with a figurehead for a disenfranchised Jewish noble family anchored to everything helps?

You do realize that the word son and the word sun, in hebrew or in egyptian, aren't even remotely similar don't you? The word Christ does mean the anointed one, that is what the Messiah is. Jesus *is* the Christ. In regards to Horus being Christ, and a lot of other things you said, please take a look at this:

http://conspiracies.skepticproject.com/articles/zeitgeist/part-one/#horus

Are there some pearl's of Jesus's wisdom I missed? Thus far I have yet to come across anything that didn't strike me as either a rewording of things wise men had preached for 1000's of years previously, or a power play by an unscrupulous or deluded individual.

Read the gospel of John and pray to God and ask Him to help you understand it.

I happen to know its hotly contested even to this day but lets for the sake of this just take it as a given. When I said "at best a fabrication" it was because I consider the historical figure to be an impostor and a fraud. If anyone was a "true" messiah then John the Baptist and moreover Simon Magus are far better contenders but then that's a colossal can of worms I'm not sure I can be bothered to open at the moment.

John the baptist said he wasn't the Messiah and Simon was outdone by Philip.

I'll just say in summary that I am of the opinion that Mr. Ben Yosef and his crew were plotting to return the house of David to power but largely failed in the end as the Roman establishment usurped most of the legacy they tried to create (though not entirely).

The missing part of this theory is the explanation for the empty tomb.

Either way they worshiped and championed a being (Psychological archetype) which I feel I have little choice but to call Satan i.e. the God of Abraham. This alone is a pretty major indictment for me and any historic figure that puts said "being" at the center of their belief system will garner my suspicion.

How can the God that appeared to Abraham be anything but malevolent if the accounts in the Torah and Quran are accurate?

The quran isn't accurate, but if you read the Old Testament without humanistic glasses on, you'll find it was the humans who were malevolent and God was who long suffering with them.

@ shinyblurry

This had already turned into an essay and I didn't want to take up even more room by quoting you verbatim so I've tried to break it down to save space.



1. "Except that?"

As for the other bits

A. "The earliest records of Mithraism bear no similarity to Christianity at all....."

Apart from all the same major dates for festivals and holy days (25th dec etc.), the entire symbology of dieing on a cross for three days then being resurrected, the "last supper" with 12 disciples, 3 wise men from the east bearing gifts. etc. etc.

Speaking of which............

Pagan & Gnostic traditions are deeply intertwined to the point where one could consider many examples to be one and the same. Mithraism would be one such example. Pagan just means many Gods/worship of nature & archetypes in the human psyche. Mithraism fulfils this definition but it also fulfils the Gnostic one i.e. it teaches that one finds god of and within oneself, not as an external force, or indeed a force which is separate from oneself.

But then the Catholic Church did it level best to suppress and destroy any trace of Gnosticism through the ages so its no surprise to me that you're not entirely familiar with it. (most people haven't even heard of it and those that do tend to be under the misapprehension that its a Christian thing (again understandable under the circumstances))


B. "Actually, they came from a progressive revelation of Judiasm which preceeded all of that."

I'll come with you a little on that one. Before Rex Mundi (Jehova) showed up to fk everything up for them the Kabbalistic (and essentially Pagan) Jews possessed great wisdom and insight. Naturally not all of this was lost! (though after Solomon passed it would appear a regrettably large amount was)


C. "What Jesus did not teach that came from Judiasm was wholly His and entirely unique, and they came from the mouth of God Himself."


I'm not sure I even want to grace that with a response. How could you possibly know what came from the mouth of God to a man 2000 years ago? If you say "because it says in the bible" please don't expect a sensible reply (I'm happy to fight non-sense with none-sense)


D. "The difference is Jesus Himself. You could take buddha out of buddhism, or zoroaster out of zoroastrianism and you would still have something. Without Jesus there is no Christianity."

^This one amused be greatly. I would say Buddhism & Zoroastranism were clearly superior for exactly that reason but that's not what I think you were alluding to?

E. "The Jesus myth theory isn't taken seriously by even skeptical bible scholars. There is more evidence for the existence of Jesus Christ than for Alexander the Great."

I happen to know its hotly contested even to this day but lets for the sake of this just take it as a given. When I said "at best a fabrication" it was because I consider the historical figure to be an impostor and a fraud.

How can the God that appeared to Abraham be anything but malevolent if the accounts in the Torah and Quran are accurate?

(I hope that made sense towards the end, getting very late & tired here...)

^ You can make all of that make sense by simply shifting your epistemological position to the only ones which truly make sense i.e. phenomenology &/or perspectivism.

To rephrase that in less impenetrable terms:
"Materialism" (or in your case I assume "Scientific Materialism") that is to say 'matter is primary', from a philosophers POV is a deeply flawed assumption. Flawed because there appears to be not one experience in human history that did not occur entirely within the mind.
When one see's say a Dog, one only ever experiences the images and sensations occurring within ones mind. You don't see the photons hitting your retina, only the way your mind as interpreted the data.

However the opposite position "Idealism" (mind is primary) is also fundamentally flawed in the exact opposite way. If our minds are the only "real" things then where exactly are they? And how do we even derive logic and reason if there is not something outside of ourselves which it describes? etc. etc.

Philosophers like Husserl, Heidegger and Sartre' got around this by defining a new category, "phenomena". We know for certain that "phenomena" exist in some sense because we experience them, the categories of mind and matter then become secondary properties, both only existing as definitions we apply retrospectively to experiences. i.e. stuff happens and then our brains kick in and say "that happened because of X because in the past X has preceded similar experiences" or "that thing looks like other examples of Y so is probably Y".

The problem then is that this appears to come no closer to telling us what is objectively happening in the universe, it's more like linguistic/logical housekeeping. The phenomenologists and existentialists did a superb job of clearing away all of the old invalid baggage about how we try to describe things, but they did little or nothing to solve the problem of Kants "nouminal world" (i.e. the "real" stuff that we are experiencing by simulation in our minds).

Its stumped philosophers for centuries as we don't appear to have any way to ever get at this "nouminal" or "real" world we naturally assume must exist in some way. But....

I reckon ultimately one of the first western philosophers in history nailed the way out 3000 or so years ago. Pythagoras said "all is number" and due to the work of Euler, Riemann and Fourier in particular I think we can now make it stick. (yeh its turning into an essay sorry )

Without wishing to go deep into a subject you could spend half your life on; Fourier transforms are involved in signal processing. It is a mathematical means by which spatio-temporal signals (e.g. the vibration of a string or the movement of a record needle) can be converted with no meaningful loss of information into frequency (analog) or binary (digital) forms and back again.

Mathematically speaking there is no reason to regard the "signal" as any less "real" whether it is in frequency form or spatio-temporal form. It is the same "signal", it can be converted 100% either direction.

So then here's the biggie: Is there any reason why we could not regard instrumental mathematical numbers and operations (i.e. the stuff we write down and practice as "mathematics") and the phenomena in the universe they appear to describe. I.e. when we use man made mathematical equations to describe and model the behavior of "phenomena" we experience like say Physicists do, could we suggest that we are using a form of Fourier transform? And moreover that this indicates an Ontological (existing objectively outside of yourself) aspect to the mathematical "signals".

Or to put it another way, is mathematics itself really real?

The Reimann sphere and Eulers formula provide a mathematical basis to describe the entirety of known existence in purely mathematical terms, but they indicate that pure ontological mathematics itself is more primary than anything we ever experience. It suggests infact that we ourselves are ultimately reducible to Ontological mathematical phenomena (what Leibniz called "Monads").

What we think of as "reality" could then perhaps be regarded as non dimensional (enfolded) mathematics interacting in such a way as to create the experience of a dimensional (unfolded) universe of extension (such as ours).

(R = distance between two points)
Enfolded universe: R=0
Unfolded universe: R>0

Neither is more "real", they are simply different perspectives from which Ontological mathematics can observe itself.

"Reality": R>=0

I've explained parts of that poorly sorry. Its an immense subject and can be tackedled from many different (often completely incompatible) paradigms. I hope at the very lest I have perhaps demonstrated that the Holographic universe theory could have legs if we combine the advances of scientific exploration (i.e. study of matter) with those of Philosophy and neuroscience (i.e. study of mind & reason itself). The latest big theory doing the rounds with neuroscience is that the mind/consciousness is a fractal phenomenon, which plays into what I've been discussing here more than you might think.

Then again maybe you just wrote me off as a crackpot within the first few lines "lawl" etc..
