The debate whether math is created or discovered goes back at least 2400 years to Plato. He fell on the side of discovering eternally existing ideas.
The suspect the full spectrum of mathis a combination of both. Some of the more complicated proofs sound more like engineering.

Mandlebrot magnificiation blurs out when you use single-precision floating point. Double precession gets you about another 25 powers of two. I'd go for 128-bit precision to really explore Mandelbrot. Its rarely implemented in hardware or software. http://en.wikipedia.org/wiki/Q...

I dislike the two-sytem status quo too.

At least show both parties are conscious and not unwilling. But I ma not sure how to avoid falsifying consent, say of a stoned person. This app probably just kicks the stone sone the road a little.

If someone loses their employment becasue this app is misused to punish someone, is the author liable? Common carriers are generally immune to the content passed through them. ISPs are partially immune. But DRM, drug trades, underage porn without due dilligence can get them in trouble. But what about software authors?

Electromagnetic force created chemical bonds and the illusion of substance in normal matter. Even though normal matter is 99.9999% "empty", EM chemical bonds keeps solids and liquids from interpenetrating each other. Since dark matter doesnt seem to have EM chemical bonds, it just difuses through the general emptiness of normal matter. It just may make us feel a little heavier than were really are from just normal matter.

To get likely first use age. Another example. oldest clothing evidence is about 30K years. But lice genetics points to clothing lice evolved about 70K years ago.

Disney documentatary about orphaned boy chimp adopted by a male adult (unusual). They used stones to crack open nuts. It is not an easy skill to learn. They did not reshape the stones. This suggests stone tools used many million years earlier than than this.

He proposes urban living, nuclear power, and GMO, to chargin of faux-liberals.

Various googled websites calculate fossil fuel usage for every citizen int he developed world is equivalent to the labor of between 100 to 200 slaves in the old days. (not including their upkeep) Granted a lot of this is wasted in our luxurious "suburban plantation" lifestyle. But could a standard of living be kept in fossil fuel free society?

It means more work to design new courses, more certifications, and more areas of evaluation. Since teachers are a major part of system, you have to get them to buy in.

The most famous induced earthquakes was Rocky Flats outside of Denver in 1965. It was a waste injection well like these fracking-waste wells. Colorado also has had M5 quakes from agricultural salt water injection in the west near Rangley and coal methane waste injection south near Trinidad.

Quakes may be associated witht loading or drainign of large water dams. The 2008 Sichuan China quake could have been one of these.

Geothermal energy projects sometimes have induced quakes. Most geothermal project inject water for heating.

Must take a vacation from screens now and then.

It just that these are played in computer cafes rather than at home.

Heavy veido game use is an issue for some young men in the USA.

The 2011 quake that clobbered the nuclear reactors in Japan was three historic faults going off at once and one of the largest quakes in recorded history- a rare M9 quake. Although there was a Tsunami seawall and nuclear shutdown systems, they had not designed for this large an earthquake.

Ditto the 2008 China Sichuan quake- it broke several nearby faults, resulting in a unexepctedly large quake. Neither China nor Japan had seen quakes this large in these areas in over a thousand years of recorded history.

So USGS seismologists are rightly concerned whether this could happen in the US.
