There is much speculation by some, as to how the flight computer aboard the Apollo missions managed to get men to the moon when it had just a tiny fraction of the computing power of something like a modern smartphone. But this is quite misleading as there was not one solitary computer controlling the Apollo craft, there were 4 computers and no fancy touch screens, GUI’s or other things in a typical computer of today to waste resources on. The first of the 4 computers was the Saturn Launch Vehicle Digital Computer or LVDC, this got the rocket from the …

For all of the celebrations surrounding the first manned lunar landing of Apollo 11 in 1969, what is forgotten today is just how close they and the other Apollo missions flew to the edge of disaster. Apollo 11 came within seconds of aborting the landing because they had over shot the landing area and were running low on fuel. This was only one of several issues with the Apollo missions that arose that could have led to the loss of the mission and crew, though as it turned out only Apollo 13 came close to this happening.

The painting “Nude, Green Leaves and Bust” by Pablo Picasso became the most expensive in the world when it sold for $106M at Christie’s in New York in 2010. However, if you had a copy, a fake, one that looked identical but was not the original, it would be worth a tiny fraction of that, maybe the cost of the materials required to make it plus a bit for it aesthetic value.

What would happen, if one day you woke up and time no longer existed?,  I’m not talking about stopping time or what we may think is the definition of time. I mean no time, no flow from past to present to future, no entropy, just now. No clocks or calendars, no hours, minutes, seconds, days, years, millennia, aeons just … now.

Now, everything in your life, all your memories of your past and what is …
