Two has many properties in mathematics. An integer is called even if it is divisible by 2. For integers written in a numeral system based on an even number, such as decimal and hexadecimal, divisibility by 2 is easily tested by merely looking at the one's place digit. If it's even, then the whole number is even. In particular, when written in the decimal system, all multiples of 2 will end in 0, 2, 4, 6, or 8.
Two is the smallest and the first prime number, and the only even one (for this reason it is sometimes called in a famous example of mathematicians’ 'huomour', "the odd(est) prime").
Two is the first Sophie Germain prime, the first factorial prime, the first Lucas prime, and the first Smarandache-Wellin prime. It is an Eisenstein prime with no imaginary part and real part of the form 3n - 1.
It is also a Stern prime, a Pell number, and a Markov number, appearing in infinitely many solutions to the Markov Diophantine equation involving odd-indexed Pell numbers.
It is the third Fibonacci number, and the third and fifth Perrin numbers.
Despite being a prime, two is also a highly composite number, because it has more divisors than the number one. The next highly composite number is four.
Meanwhile in the year 2CE, Wang Mang began a programme of personal aggrandisement, restoring marquess titles to past imperial princes and introducing a pension system for retired officials, while placing restrictions on the Emperor's mother, Consort Wei, and other members of the Wei clan.
Which may explain why they were so revolting the following year.
But, as we all no doubt remember, the most important thing about 2 is that “two can be as bad as one. It's the loneliest number since the number one”

Christ-on-a-bike!!!!
Who'd have thoght the internet could be so dull?
Just like the Des Lynam version of the popular TV game show, your countdown is in need of an added 'something' to give it interest :-)
Except the number of hits per hour on the blog actually DECREASES after YOU'VE posted.
