So exactly how can 1+1 be = 1? This is how!

If u're reading this post with no idea why the title is abt 1+1=1, read two posts down....

Get the question now? Ok, so now let me explain to you the theory behind 1+1=1, it may sounds boring to some(u can change channel now, come back 5 mins later), or it may sounds awfully familiar to others. So everyone knows computers work in 1s and 0s, but have u considered how the millions, billions or even trillionsss of 1s never add up to form a 2 or smth bigger? (Come on, computer uses maths too, u dun expect them to form words with 1s and 0s rite?)

In order to simplify operations and stamp out distortions in signals, computers are designed to read only 1s and 0s, think of it as a yes or no thing. So the 1+1 here is no exactly your numerical 1. In order to ensure the smooth operation of computers, laws and guidelines are drawn up, just like how we keep ourselves from self-destructing.

So Boolean came up with a set of 'laws' which governs how these digital signals are read, in his 'laws', he said that 1+1 should rather be read as 1 AND 1 and the answer will still be 1 since there's no 2 in digital code. Think of it as a yes and yes answer, since it can only be yes or no, yes and yes is still yes. This set of 'laws' he calls them the Boolean algebra or Boolean Logic. Thus the word in the blank should actually be the word Logic. Lame right? After writing all these, I also find myself at the extreme end of lameness.

For those who up to now have no idea wad mi previous was all about, a general translation means 'Engineers are boring ppl, because we only study, I'm an engineer, that's why i'm so boring. I write here now becoz i know no one understands wad i write.'

Something interesting to share about wad happened in NUS, today they were giving out condoms in Arts to advocate prevention of AIDS(not advocating liberal sex!). They put up some survey results which I happened to read abt, it says 49% of NUS students are sexually active, but 40% of NUS students do not practice safe sex. By some simple math, that makes 20% of NUS students are in danger of contracting AIDS or any other sexually transmitted disease. It could jolly well mean the person sitting next to u in tutorial class or lecture could be in this danger zone, or worst the person sitting on that exact toilet bowl u just sat on. AIDS dun spread like that, but some STDs do spread from toilet bowls, i think. So to all those *ahem* ppl out there, all the Greenpeace and Co. ppl will not complain abt too many condoms destroying the Earth, pls feel free to use them.
