What Can Frogs See That We Can't?

oritteropo says...

Hmm... now you've made me curious too. I have found a few interesting pages, but nothing specifically about frog vision apart from mentions that it's sensitive.


  • How Stuff Works has a How frogs work article.
  • The Whole Frog Project provides a virtual frog for high school biology students, based on MRI data, mechanical sectioning, and some software to allow visualising of the anatomical structures of the intact animal.
  • The UW Sea grant site has a frogs page with resources for kids + teachers that has an origami frog (among other things).


I'm not quite as sure about the single photon claim. I found a Physicsworld.com article from September 2012 talking about using a single rod cell from a frog eye being used as an extremely sensitive detector which is able to detect a single photon, but according to the original Usenet Physics FAQ (I cite an updated version hosted at math.ucr.edu) human retinas can also respond to a single photon, but have a neural filter to block the signal unless 5 to 9 photons arrive within less than 100 ms.

Also, I'm disappointed. I was hoping to learn about the optical/visual system of frogs.

Should've paid in pennies glued together to make penny pigs


i went to pay fines in pennies they wouldn't take them....I went and got quarters and when I came back they had found other warrants and threw me in the slammer for about ....15 mins. I was n the holding cell singing vespers and the Judge came in to see what the fusswas about...

They let me go and chuckled..

amonth later I'min the goodyear blimp to photograph the weddingof the pilot....Same judge went up in the gondola to perform the union...He did NOT remember me. Probably retarded.

Presentation Fight - IPad vs Surface

Sarzy says...

>> ^shuac:

Very true. And while all technology products are derivative of earlier products to some degree, I think Microsoft does more bandwagon-jumping than most. Let's look at the evidence.
Java, made by Sun. "Reimagined" by Microsoft.
Console gaming, made by Atari, Nintendo, Sega, Sony, et al. Microsoft gives us Xbox.
Online Music, pioneered by Napster, made legitimate by Apple. Microsoft gives us MSN Music.
MP3 player, pioneered by Rio, made super popular by Apple. Microsoft gives us Zune.
Internet search, pioneered by Archie in 1990, made insanely profitable by Google. Microsoft gives us MSN. And Live Search. And Bing.
Far as tablet computing goes, Microsoft actually has a much bigger history than Apple. I remember MS peddling tablets back in 2001 with XP. Trouble is, XP was never designed as a touch interface. Even as recent as 2008, Microsoft tried this strategy with the Origami.
The innovation Apple made is to take its smartphone OS (whose design is based on touch) and pull it up to the tablet rather than take a full-blown desktop OS and push it down. This is the idea Microsoft is copying with Surface and Windows 8.
Other than Kinect, which is an innovative product since it is more than merely a response to the Wii, I'm not sure Microsoft invented anything. Even its flagship Office suite is based on earlier software (WordStar, WordPerfect, dBase, Lotus 1-2-3). In fact, when Microsoft first licensed MS-DOS to IBM for a huge profit back in 1981, it was essentially QDOS, which they purchased outright from some guy for $50,000. Deal of the century.
You may say, "Well Apple didn't invent the MP3 player. Why aren't they guilty of copying too?"
They are. But Microsoft's history is rife with this sort of "me-too" thing in a way no other company's is. Let me distil my point into one sentence: How many companies are copying Microsoft's products?
To sum up: Microsoft is slim on innovation, fat on looking over the shoulders of the smart kids in class...>> ^Sarzy:

Microsoft never fails to innovate their name on someone else's product.

Yes, because the iPad was, of course, the first tablet ever.



Cool story bro.

No, seriously though, you do raise some interesting arguments. The only point I was trying to make is that it seems a bit reductionist to dismiss the Surface as merely an iPad clone, when it seems like Microsoft is legitimately trying to do some interesting things with it and Windows 8, rather than just jumping on the iPad bandwagon.
