<p>Most people are aware of the fact that computers work using strings of
0s and 1s. But how do you write numbers using only those two symbols?</p><p><a href="https://plus.maths.org/content/maths-minute-binary-numbers" target="_blank">read more</a></p>https://plus.maths.org/content/maths-minute-binary-numbers#commentsbinary numbernumber systemThu, 07 Aug 2014 10:55:47 +0000mf3446150 at https://plus.maths.org/contentPlay to win with Nim

<p>In the game of Nim one player always has a winning strategy — it depends on an unusual way of adding numbers.</p>
</div>
</div>
</div>
<p>Some games are all about luck. Your winning chance depends on the
roll of a die or the cards you've been dealt. But there are
other games that are only about strategy: if you play cleverly, you're
guaranteed to win. </p>
<p>A great example of this is the ancient gam of Nim. Whatever the
state of the game, there is a winning strategy for one of the two
players. And a very cute form of addition tells you which of the two
players it is.</p><p><a href="https://plus.maths.org/content/play-win-nim" target="_blank">read more</a></p>https://plus.maths.org/content/play-win-nim#commentsbinary numbercreativitygame theorynimstrategyMon, 21 Jul 2014 10:18:30 +0000mf3446134 at https://plus.maths.org/contentColouring by numbers

<p>How does a computer understand the colours to be displayed on the monitor's screen? It's all about red, green and blue and numbers written in a special way.</p>

It's International Year of Astronomy and all eyes are on Galileo Galilei, whose astronomical observations 400 years ago revolutionised our understanding of the Universe. But few people know that Galileo wasn't the first to build a telescope and turn it on the stars.

<p><i>It's International Year of Astronomy and all eyes are on Galileo Galilei, whose astronomical observations 400 years ago revolutionised our understanding of the Universe. But few people know that Galileo wasn't the first to build a telescope and turn it on the stars.

bothered to publish his results.
