There is an autistic man from a U.S communist party and he makes the point that if humans were blind then buildings would have no window or lights, so if you were the only human with bison you would have a disability. I thought up the alternative of imagine you had to quickly move across a space...

That's a good, interesting question to which there is not an easy answer because evolution as well as technological evolution can take different paths in isolation. Even with the absence of other technology in the 1920s it would be extremely hard to envision a time when people from all 4 corners...

I was unaware that digital cameras and night vision were the same concept, and i'll admit that I don't really understand how digital cameras work so I'm unlikely to gravitate towards them very quickly. I filled out my educational history on my profile so you could quite easily read that there...

Hi I have a cheap smart phone with a low quality camera when I go to take a picture there is what I would describe as like old television static appearing in front of the image as it appears on the phone screen (although what is beyond it can still be seen). I am wondering if this is just dust...

At School physics was perhaps my least favourite subject because it has quite a strong link to maths and I was bad at maths and couldn't get my head around it. Maths was my second least favourite because it mainly concerned itself with either pure numbers or someone called Billy wanting to know...
