Numeracy

Who remembers the Weekly Photo Project on G+ This image was created for the word simplicity.  It also works for numeracy.

WPP 2015 - Week 08 - Simplicity / Minimalism

Binary

There is nothing simpler in the computer world than binary.  Either something is on (1) or off (0).  The image illustrated is 1 + 1 = 2.  To understand this numbering system you need to look at each column from the right and double the number. so column 1 (the rightmost) = 1, column 2 = 2, column 3 = 4 and column 4 = 8.  So if column 4 has a one then it equals 8 and if column 2 has a 1 then it equals 2.  To get the value of the binary sequence you simply add the numbers together.  So in the picture you have 0 + 0 + 2 + 0 = 2.  If it had been written as 1010 then it would be 8 + 0 + 2 + 0 = 10.  This as simple as it gets and is the way that all computers run their programmed instructions.  EVERYTHING is either 1 or 0, on or off.  It doesn't get any simpler than that :)



Wind up

This car looks like it might be spring powered...  Judging by the size of the key it must be a big spring too. Qualifies for On this day as I took it a short time ago



White night

Five years ago Penny and I went to white night in Melbourne.  We got there at about 4am in the morning in an attempt to miss the crowds (Overnight they estimate that they had 500,000 visitors to the city).  We saw these three acting up for the cameras in the waterwall of the NGV.  Hopefully we can have big events like this in the future.
