No face shield, no dark glass with welding? I wonder how cloudy his eye lenses are going to be and how many holes he's gonna burn in his retinas...

Ah--not tears then--detachments.
Sad to hear---

But--lasers and retina scarring---it's a real thing.

Superb use of a laser---and glad it worked. The mechanism of it working, if I recall correctly, is the burning and scarring of the retinas that have detached "scars" them down onto the the back of the eyeball again...

It's how they stuck my dad's retinas back on after they both detached. He spent the rest of his life staring hard at things in public and when asked what he was doing he would say "I'm trying to make the lasers come back out."

I thought lasers ...were bad for retinas...

Hell yeah, I want to promote this but people on the Sift don't give a rat's ass about good music unfortunately.

Definite The Fall, Mark E. Smith vibe, which I like but sorta hate because come on man! Don't copy Mark E. Smith he'll stick his smoke in your retina and pour scotch down the hole!! But the discordant krautrock vibe... I am always up for krautrock rehashes lol, when they're jamming reminds me of some of my old bands

Bad catnip trip? Look at the irises. Poor thing's retinas must be getting fried.

I think my work's 15" MBP (Retina; early 2013) has that NVIDIA crash problem (e.g., a Kernel panic from last year but never saw them again], display freezes [think I can get out of it if I put it to sleep and wake it up, but need to retry it for the next crash to confirm], but it is SO rare that it crashes.

They have without doubt some of the most quality engineered laptops on the planet. I have a Macbook and my wife has an Asus Macbook clone (straight down to the silver-polish finish). And yes, hers cost less and has a dedicated GPU so she could play games on it (if she had any interest in games) but the Macbook is lighter, keeps the battery charged longer, has a much more beautiful display (Retina vs Full Hd), is much more comfortable to type with, and the touchpad is just freaking heaven to use. I now hate having to use touchpads on any Windows laptop, even my bootcamped Mac!

And you hit the nail on the head about using the right tool for the right job--I work with video as part of my job sometimes and I don't think I can ever go back to video editing on a Windows machine. I can do it easier and faster on an OSX device.

I think also the initial outward simplicity of Mac operating systems makes them ideal for people who don't want to or don't have time to become "computer people" and worry about dealing with downloading the latest drivers or all of the other BS that you need to constantly deal with on a Windows machine. I especially wish my dad, who is constant calling me and my brother for help with his PC, would just switch over to a Mac as it would solve probably 95% of the issues he calls us about.

Ok so, Judge me with your opinions here...
But, I knew all this, intuitively.

I knew what was happening. I understood the persistence of vision as a given phenomenon. I can actually induce this persistence of vision on things as I look at them. Slowing down and increasing this persistence. Not a great amount, but I can do it enough to observe it. This means I can look at any normal object and move my head slowly to the side and watch the image degrade on my retina as I move my direction of vision to the side.

Now Destin, immediately saw this as a trick that fooled the mind into believing the image was a solid. But I wasn't fooled. Why wasn't I fooled? HAve I just been exposed to this before, and my mind is telling me the truth, thus negating the illusion?

I've seen similar tricks like this before, like on a wheel, to create an image, but if I concentrate I can see and immediately comprehend what is happening. I can stare long enough to break up the image and loose the illusion, and then have it come back.

I hope I'm making sense here.
So what I want to know, is, "does everyone have or not have, see or not see as I do?" I assumed we all did. So much so, that I've never had a question in my mind as to how this worked or that it was a trick.

Tell me I'm crazy, that's fine. But I'm interested in what other people are perceiving.

A collision with two cars head on with a combined impact speed of 200km/h is not actually equivalent to this test at all. If you do the math you actually work out that two cars each travelling at 100km/h hitting head on generate the same forces on their occupants as a single car hitting a fixed barrier at 100km/h. (reference, sadly light on mathematical proof)

The 5th gear test at 193km/h resulted in occupant deceleration of 400g (100g is survivable, although you can expect injuries such as detached retina, and I have heard of someone surviving 179g). Robert Kubica's accident resulted in a peak g-force reading of 75g.

I think they approximate it by measuring the shape of the everything by shining light through. The shape of the cornea, lens, and retina and how projections through it render on the retina.

fixed.
The combined destructive/creative forces of nature can really produce some retina shattering beauty.
I've never seen anything nearly as gorgeous as a rift volcano in full eruption.
13 more points and I'll definitely give this *quality

From http://aveugles.org/felix-impressionne/ this was filmed at the summer camp of the Fondation des Aveugles du Québec (Quebec Foundation for the Blind). (and therefore *canada)

Felix was born 3 months premature and his retinas detached due to oxygen toxicity at birth, and at first they were unsure if he would ever talk... so his family is very happy that he has turned out to have such a talent for music.

Felix loves BB King, of course, but also Les Colocs, Bernard Adamus, Stromae, Robert Johnson and Eddie Lang. He takes advantage of the summer camps to bring his guitar and put on a show.

It also says some other stuff about how the camp provides opportunities for blind children like Felix, and they hope he continues to flourish through music.

Resolution isn't really relevant. Standard def tv is more realistic than the latest video games even at 4k.

Pre rendered photo real cgi has been around for several years now, but one of the hardest challenges are human faces, because we have evolved to spot incredibly subtle signs within faces. Look up the Uncanny Valley.

To answer your question directly, the human eye can basically detect ~300 dpi at reading length (hence Apple marketing "retina" screens)
