This is pretty much the level of my driving ability.

The 19lb alloy RC10 now makes sense!

If i could drive a billet block around I would.

Cool, but useless. A goldfish has no memory, virtually no intelligence, and no use for terrestrial mobility.

Put an octopus in there, you might have something!

True, we'd all like to think that goldfish is actually doing something, but what it's mostly seeing from the inside of that tank is its reflection.

The image-mapping is interesting, but it's a case of technology imparting a false sense of intelligence upon a fish that is otherwise clueless as to what's going on.

This could've been so much more compelling if it was done with a rat.

Pretty sure a rat would have drowned

But it would've been compelling for awhile.

Not that I'm championing goldfish but that 3 second memory thing is not accurate. An octopus though yeah would be a bit scary. That's all we need cyborg cephalopods.

Not necessarily. Can fill the tank with oxygenated fluorocarbon liquid and the mouse wouldn't drown.

This was one of the pics in my chem book from college:




On the gold fish....in the pet store they tell you not to tap the glass on the tank because it scares the b'jeezus out of the fish. Imagine what that fish must've been going through in the fish tank on wheels. As the tank shook from moving the fish's instincts told it to flee....which just cause the tank to move more....which caused the fish to want to flee more....etc.

It's not even 3 seconds. They have ZERO object permanence; as soon as something is removed from their sensory perception, it ceases to exist to them. By comparison, domestic cats have approximately 16 hours of of object permanence memory. A human being's can be for life, if the memory has enough significance to be stored as permanent (although object permanence doesn't begin to manifest in the human brain until about 10-12 months of age).

Remember, short term memories are chemical, while long-term are a physical change in the brain.

Memory is different from behavioral modification studies like

Scientists found that fish trained to respond to certain sounds in captivity still reacted months later when they heard them in the wild.

in which the permanent memory is forced by repetition (often extreme).

I'm pretty much the same way Once I close this webpage you all cease to exist

what's the 100g weight in the bottom of the beaker for?

True...even flatworms have a very basic immediate memory of what stimulus causes a negative reaction vs. a positive one. That's not an indication of intelligence, of course.

Mice float.
