How to See Without Needing Your Glasses

Deceptive Shadows

"Look at this people Eric" Street photography-like a boss

westy says...

could just shoot with a smaller digital camera and then Photoshop it to look the same , but then I guess it would not be as "artistic" that way.

not that I have anything against shooting with film , but its pretty inconveneant and if your end product can be achieved without using film might as well not use it if your going to inconvenance yourself why not go to the exstreem ? why stop at a film camara why not use a pinhole camera , why not stop and paint every person ?

I can see a justification for using film is that you like the random artefacts and inherent qualities , but again you can achieve those qualities using Photoshop only with the advantage of full artistic control.

What a year on Earth really looks like

honkeytonk73 says...

The Earth is actually flat and resting upon pillars. Covered in a blanket of night with pinholes which we know as the stars. The sun is a flaming chariot. The fast moving dots against the blanket are the various gods moving about. We are at the center of existence because we are special... and it all was created in the span of a few days a mere 6000 years ago. At that point humanity spawned from a single male, and a female clone spawned from a rib bone. Soon after the 'lesser' female was tempted by a talking snake into eating an apple she was told not to. Of course then.. shit hits the fan. You listen to God or you get your ass whooped. Now.. don't ask me about how two individuals spawned a whole species... as obviously their offspring would have had to procreate with each other, or with their mother to get the first few generations going in full swing.

Perfectly plausible start to all existence if you ask me... not this fancy schmancy science stuff. Hmph!

Transparent Laptop Screen

bmacs27 says...

Dude, that's so annoying, the glare, it pains me. Also, does that mean that people behind the screen can see what you're doing? Does anyone consider the usefulness of the stuff they make?

As for the glasses, you are right, it would be difficult to focus both on the image plane, as well as the objects at a distance. One possibility would be to put an artificial aperture over the eye in order to create a "Maxwellian View". In other words, you can make the eye more like a perfect pinhole camera creating theoretically infinite depth of field. The only problem with that solution is that you lose a lot of light, and would need a very bright display (not to mention a very bright world, if you would also like to continue seeing that).

Man in the Box: Facebook Abuse

Payback says...

I haven't joined Facebook because I'm not narcissistic. I meet my friends in the real world, keep aquaintances at arms length, and use web-enabled pinhole cameras to spy on my ex's, just like my daddy did.

Best bits from the Century's Longest Total Solar Eclipse

Diogenes says...

this eclipse was really a huge letdown for me... and video reportings like this actually have me scratching my head and wondering what the hell happened...

july 22nd - from 8am to 10:30am i was near the top of taiwan's 2nd highest mountain, hshuehshan or snow mountain (3886m), avidly watching for this phenomenon on a very bright and nearly cloudless day

i literally saw very little to nothing -- i know, i know... even people here in taiwan are posting photos and saying the 'sky dimmed noticeably' ... but i noticed no dimming whatsoever, and could only see a very slight after-image-type of bright 'elipse' layered over a small part of the sun if i quickly glanced away and back (don't worry, i was wearing some nice polarizing sunglasses)

i took many digital photos and video throughout this period and they also show nothing special, but perhaps that was simply my camera or settings (though i tinkered with all possible settings including time lapse

the only other indication i had that 'something' was occurring was in my holding up a pinhole card to the sun and casting its shadow onto another piece of white card i would set on the ground - even though this showed that something was obscuring the sun, there was no visible dimming whatsoever to the 'not-quite' naked eye

anyway, very disappointing results for something that i thought i had carefully anticipated and planned for

Ask Astronaut Greg Chamitoff: Hallucinations?

honkeytonk73 says...

Another few questions ...

"Have you tried poking pinholes in the cloak of night to make new stars?"

"When the ISS orbits around the edge of the Earth... what does it look like on the other side? Lots of hanging tree roots? Is the Earth really supported by pillars as stated in the Bible?"

"Can you see God's big castle floating in the clouds above Earth's surface? Any flying people with wings, talking snakes, or lush gardens?"

Emergency Eyeglasses

You better do it the octopus way!

As promised, here is the transcript, to the best of my transcripting abilities. I've shrunk the text size to keep it from being any more gigantic than it has to be. Copy and paste it if it's too small to read.

It's interesting when people speak of areas of evolution for which we have no explanations. All the fundamental concepts of the evolutionary process are understood at least at some fundamental level. Now, are there gaps? Not gaps in the sense that people think. People, now, speak of gaps, for example, in the record. You know... we don't have fossils from before the Camrbian Explosion, but so what? The record is complete; it's not complete by means of fossils. You see in Darwin's time the only way to reconstruct evolutionary history was by studying fossils, by comparative anatomy, comparative embryology, biogeography. It was 150 years ago; science has advanced tremendously. We can now reconstruct evolutionary history with much more powerful methods; the methods of molecular biology, by looking at DNA, by looking at proteins and with these methods we have reconstructed the record completely. We can go back to the organisms, a group of organisms, called LUCA ('L' 'U' 'C' 'A') for the Last Universal Common Ancestor. We can find the common ancestors of all animals, common ancestors of all plants, of all fungi, of all bacteria. We can find the... we can reconstruct the histories of the common ancestors of plants and animals and fungi and bacteria going back to the very beginning. We don't know all the details, because who wants to know all the details? If you are studying the Rocky Mountains, you don't want to have, necessarily, a map where every st.. every tree and every rock is there. If you want to know the details of a particular area within the Rocky Mountains you can go there and study as much as you want and find every little rock, every little leaf, every little tree, every little plant there. The same with evolution. We can now look at any area of evolutionary history and we can understand it with as much detail as we wish. The methods of molecular biology are so powerful, are so quantitative, and also so redundant, we can study anything we want with as much detail as we want. Now there another way in which the people who propose.. propound intelligent design speak of as... about, um... you know, gaps in the record. How did the eye come about? Well we understand now at the genetic level [unintelligible], we actually understand that at almost every other level, they make the unwarranted and erroneous assumption that if something is complex, and every part depends on every other part, that it could not have come about by evolution. It's like a watch. It does not help to have one little piece, or the other piece, or the other piece. You have to have them all or you don't have a watch, but that's not so with organisms. So we have in mollusks today, these are snails and clams and so.. and squids, we have an example.. an example of eyes which go from the simplest to the most complex. I'm going to speak about eyes because the eye is one example they use, unless you have everything, unless you have the cornea and the lense and the retina and the... and the optical nerve, having one part of this alone doesn't help. Well in mollusks, and in some mollusks called limpids, they have something that you can call eyes. They're just a few pigmented cells linked to single neurons, nerve cells, which carry the information to the primitive brain of these creatures. Just a few pigmented cells. Then we have mollusks which have more pigmented cells and some of them forming a kind of cup which allows to detect the direction of the light. Then we have what are called pinhole eyes which are this cup, still a little more extreme and a little more sensitive-to-light cells, and more nerve cells, and then you have... we have animals, still speaking about mollusks, which have just simple refractive lense as well as the sensitive... light-sensitive cells which eventually in advanced organisms they advanced to the... gave rise to the retina. And you go all the way to octopus and squids which have an eye very much like ours: has cornea, has a lense, has a retina, has muscles to move it, has a.. a optic nerve. Curiously enough the eye of the squid is better than ours in that we have a substantial imperfection that they don't have. For historical reason, that's for evolutionary history of how the human eye came about, the neurons that register the signals in the retina are inside the eye. So for those signals to go to the brain, these nerve cells get collected in the optic nerve, the optic nerve has to cross the retina so we have a blind spot. Now squids and octopuses have the nerve cells connected to what is the retina from the outside. So they collect into what is the optic nerve and they send the signal to the brain without having any blindspot. Well the... the point I am making is that there are complex organs and functions that we may not know in detail, but any time we investigate one of those we discover the details. And it's again, I'm going to put it bluntly, blasphemous to try to think of a God who is there waiting for something from time to time to come and intervene: "now I'm going to make an eye". Primitive organisms don't have eyes so God waited a few thousand million years - 2 and a half, 3 thousand million years - in order to have organisms with eyes, then later on did this and that. This is what the theologans in the old times called the "God of the gaps". Heresy, trying to justify God to account for things we don't know. You know, fill in the gaps. For things we don't know and aren't knowlegable by scientific research... we have science, we should do scientific research. We should not be putting this God as an engineer that is trying to fix little things from time to time. What sort of vision of God is that? Moreover there is another problem and it is that the implication of intelligent design is that God is a very, very bad engineer. Think of the example that I was telling you a moment ago, of the human eye. I mean, an engineer that could have designed an eye with the optic nerve having to cross the retina would be fired. You better do it the octopus way. An engineer that would have designed the human jaw would be fired. Our jaw is not big enough for all our teeth, so we have to pull the... the... the wisdom teeth and very often have to straighten the others and the orthodontists make a very good living straightening the teeth because we have too many teeth, too large for our jaw. An engineer that would have designed the jaw that is not big for the teeth would be fired. God making these trivial, obvious mistake in a universe of design. Well their God does these things, certainly not mine. I don't want to have to worship a God that did this... um, not smart enough to do as well as a human engineer.
