What does an IQ of 70 entail, cognitively, emotionally, etc.?

Posted: 27 Dec 2015 05:46 PM PST

I began watching Making a Murderer on Netflix and was shocked to hear that the protagonist of the documentary had a documented IQ of 70. Realizing that my assumptions about that are probably all wrong, I'm wondering: what, if anything, does such a thing tell us about a person?

Does sending a text to someone in a stadium full of people take longer to deliver due to the mass amount of devices being used in such a concentrated area?

For example, I sent a text on my iPhone today to my sister, who was at a football game. I noticed it took a bit longer to say "delivered", when usually it's nearly instantaneous.

Since all matter has a gravitational pull, would antimatter have a reverse gravitational "push?"

How long does it take for a large, non-spherical object in space to become spherical?

Let's say an object with about the same mass as say, the Earth, but in the shape of a cube. I assume it would turn into a sphere, but on what timescale?

If I derivate a function and then integrate it information is lost, why?

Example :

y= x2 + 2

y' = 2x

∫ 2x dx = x2 + c

Why can't we know if c is 2 or 6 or 7383738?

How long does DNA last in blood in conditions that aren't ideal?

Posted: 26 Dec 2015 09:22 PM PST

I've learned the "6.8 million years in ideal conditions", but for something like crime scene investigation, how long could DNA last in blood in conditions that aren't ideal, i.e. weather, heat, moisture, etc.

Best case scenario vs. worst case scenario would be appreciated.
