AI Thread Summary
The discussion revolves around three experiments exploring motor skills, eye dominance, and color perception. In the first experiment, participants found it easier to rotate their non-dominant leg while writing with their dominant hand, suggesting that tasks involving opposite sides of the body may be more coordinated. The second experiment aimed to determine eye dominance based on handedness, but results were inconclusive for some, indicating a potential complexity in the relationship between handedness and eye dominance. The third experiment involved staring at a red dot, after which participants reported seeing a bluish circle, attributed to the concept of complementary colors, where red and blue are opposites. This phenomenon occurs because the red cones in the eyes become fatigued, leading to the perception of the complementary color. The discussion highlights the need for clearer explanations of these observations, particularly in relation to neurological and physiological principles.

Experiment 1:

Rotate your dominant leg clockwise and use your dominant hand to write the number 8 on a piece of paper. Do the same thing except rotate the other leg. What are the results and why?

I kknow that its easier to do the second scenario but how can I explain it? All I can think of is that two parts are controlled by opposite sides of the body...help? Why is it easier?

Experiment 2:

can u predict right or left eye dominance based on handedness? The experiments makes u hold a pencil up to a corner of the room, then u close each eye, and when you close your eye, once u open it, the one in which the pencil moves more is dominant.

My results were inconclusive but I don't know how to explain it

Experiment 3:

Stare at a red dot on a piece of paper for about 20 seconds. Turn the paper over, what do you see, and why?

I saw a bluish circle and I think its because I used all the red cones so I used the ones i have left, but why is it blue and how do I explain the rest of it?

help with this is greatly appreciated, the sooner the better, my lab book is due monday november 17 at 12:40 pm EST, so please...hurry

Look on the web for a circle diagram that depicts the complementary colors, red and blue are opposites..

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
