What is your perspective on the origin of consciousness? Do you beleive that science can make reasonable considerations on what the origin of consciousness is?

I've seen it on this.
I want to learn to use newer math resources better. I am 54 and when I went to college calculators were just being marketed.

I want to learn more on using my TI-82

I'm curious about the origins of mystic gems like quartz & topaz. Are these stones found in the ground that way, or are they treated?

but smaller. Presumably their muscle is alot more efficient than ours. (even more efficient than that of those hard working romans ;) ) Is there an advantage to humans becoming weaker? Is it an unwanted side effect of intelligence - that our bodies become less important and therefore are able to deteriorate whilst we remain viable?
If so, in 100,000 years, will all humans be confined to wheelchairs?

I know that if the class has two outer limits, e.g. !-3 then you just add the two limits and divide by 2, but if you have one without and upper limit, e.g. 60+ how would you work out the mid point?

Not the best place to ask, I realize... but I am wondering if any 'psychics' (those with a heightened sensitivity to intelligences without traditional interfaces like bodies and such), especially those in the city, experience a strange phenomenon in the energy spectrum of the strange organism we call the city?

I don't mean muderers or terrorists, or anything like that. I mean, we are in a time where tectonic movement is speeding up (extremely slowly, though), faults have greater tension building because they cannot release minor quakes, the Earth's magnetic field is due to reverse, we are due for a new iceage, more violent volcanic activity more often, greenhouse gasses being realesed not by just human activity, but by all living things (not helped by shortage of plants to provide oxygen and get rid of CO2).
And on top of all that, the Yellowstone Supervolcanoe [which erupted last almost exactly 7000 (or 70,000- I don't remember exact)] erupts every 7000 (or 70,000-I'm not sure which) years.
I'm not asking if humanity can survive it if it all happened at once- I'm asking how bad is the danger and will any life at all survive it the world unleashes it all at once.
I'm not saying that it will happen all at once-it probably will be spread out over the next 1500/3000 years. What will happen?

like eye and hair color, and propensity to disease, do you think it's possible that luck itself is somehow encoded into one's DNA? could people be born lucky, naturally attracting favorable events? just a thought

What would the people who buy organic goods be surprised that farmers/producers can use on compost, the land, the crop?

If you have good reason there are other non organic substances you can use in certified organic farming. What are these? Have you used them?

Is organic, really organic?

This seems to be an increasingly large gap in my education. Thorough explanations appreciated instead of cryptic one-line explanations.
