Think Tank
22.03.04 at 13:57:40
 
On my way to work in a morning, I travel on the train.  A company called METRO produce a free paper for train travellers. In the back, they have crosswords and quizzes but produce 3 different questions everyday in the Think Tank.
Last Thursday, there was a question printed, which I thought may be slightly relevant to topics posted on this site in the last few months.  I nearly got it right, I was on the right lines.
I will post the answer when I get a few answers/guesses from members, to see if they can get it.
The question is as follows:

It has 30 billion parts and its total storage capacity is around 4 million megabytes (4 terabytes).  Its distributed network handles 86 million bits of data every day via electric signals synchronised by a data bus that operates at a frequency of 40Hz.  It processes 100,000-pixel images in focus at 25 frames/sec in 2 million colours.  What is it?

I'm afraid that patience is wrong, and that it IS the Human Brain.  Grin

These extracts are taken from the official World Medical Journals, so I wouldn't doubt or question their theories as incorrect! Roll Eyes

It also proves that the human eye DOES ONLY see ~24/25 fps as that is the maximum the brain can detects and acknowledges. Grin

If you enjoy these brain teasers so much, I will ask FalconFly if it would be ok for me to post some more up for members to 'exercise their thoughts'. 

Nice try everyone, most of you were on the right track.

I think my answer was more cryptic than your question then. Have I mistranslated neuron?  Grin

It was sooooooooo easy! The 25 fps made me think about the eye... but then again.. the eye can't store anything...  Roll Eyes (well, the retina latency... ehm, another story)

And patience actually approved the numbers, didn't denied them. Am I missing something?

I still suggest, that we then limit the Framerates to 25fps in every Game and on every Display Device then...

...and await the onstorm of pissed-off Gamers (since we just made about every Game on earth unplayable) Wink

Falcon's right! That would be terrible. I think the keyword here is focus. Maybe the eye can follow 25 focused images per second. But it requires a lot more for a liquid motion.

Hey, janskjaer - do you live in the U.K.? ???

The FREE METRO paper is also on public transport in my city (Newcastle Upon Tyne - U.K.). Wink

Just wondering? Tongue

Sigh!  Undecided

As I mentioned in another topic, the reason games are using 60fps a second is as a 'buffer conditioner'.

60fps wrapped around the 25fps the brain takes in, makes these frames look smoother and faster as the eye takes them in.  Simply running a game with 25fps, doesn't provide the smooth transition between each frame swap, as 40 or 50 frames would.

Anyway, Micha, here's a double-challenge: "It disappears when you speak its name; what is it?"

I quoted the riddle from memory. The 2nd challenge is to discover the movie I extracted this riddle from...  Tongue

About the eye thingie: let's clarify this once and for all.

There is a nifty demo in FastVoodoo... I forgot which version -- 4.0 GE (XP), I think! Try it and then tell me 30 FPS are sufficient.

There's also an explanation there (about the brain taking a heavy load to interpolate between images at low FPS).
