If you’re reading this you must be using some sort of computer. Most of us have an idea about the origins of our modern computer units, but sometimes explaining the lineage of these machines leads only up to the first design. The big question is - how did we get all the way to a computing machine? We could not have gone from fire or the wheel straight to iTunes, right? What’s responsible for the giant leaps and bounds in technology that make our life what it is today? The process of science, that’s how!
So, who's up for grabbing lunch in Tokyo today?
Yes, Tokyo, Japan. Well, today this may not be a possibility, but scientists are working on new plane designs that could make this lunch date a distinct possibility.
Why can’t we stop thinking?
Try to stop thinking for five seconds.
Okay, now you’re just reading this and not-stopping-your-thoughts!!
So why can’t we stop thinking? Well, this is the handiwork of our old friend, evolution.

Ah sleep, so peaceful!
So, why do we sleep?
Well, first of all every animal with a brain sleeps. A lot of really important things happen while we are off in dreamy dream land. Sleep is when the body gets a chance to repair and process things. This allows our brain to be refreshed and our cells (throughout the body) to get repaired, an important part of how wounds heal!
In 1977 NASA launched Voyager 1 and 2, two probes boldly going where no spacecraft had gone before! After 35 years of zipping through space these ultimate inanimate explorers still work and are still communicating with us! The Voyager program has been a vital source of information used by astronomers in understanding more about our own cosmic back yard.
400 years ago lead was harnessed to wood and thus pencils were born! Today, most pencils are made of graphite surrounded by a wooden shell. The average pencil can draw a line for about 35 miles! If you're not drawing 35 mile long lines you could be writing words, about 45,000 words is the average life span of a graphite pencil.
