Okay so here are some answers to some questions :)
Where are you going
on holiday?
À France! To a little campsite near the town of
Vic-sur-Aisne in the north east about an hour and a half away from Paris. We’re
staying in a mobile home for a week and we’re going to Disney, as both James
and I want to relieve our childhood.
What games do you
play?
I’m not really a computer game type of person, although I do
have a few guilty pleasures from childhood such as crash bandicoot, spyro and
anything sims. Also pokemon. I get very competitive at board games, to the
point where quite a few people refuse to play monopoly with me anymore, as my
strategies are too ruthless. Another couple of favourite boards games are logo
(a game where you have to identify logos and answer questions about brands),
and articulate (a game in which you have to describe and guess words in a set
time).
What’s James doing?
Currently he’s led on my bed, eating biscuits and watching
me type this. However, I assume that you’re referring to what he does with his
life in general. He works as a senior administrator for a training company (basically
he’s the office gossip/holdertogetherer) . He spends a lot of his free time
volunteering for the British Red Cross, helping people in their hour of need.
Also, he’s nice to me some times.
What is your
favourite mathy thing and explain it to us?
My favourite area of mathematics is cryptography and coding
theory, which is basically the maths which keeps all your personal information
safe when paying for stuff online. I would explain it to you, but unfortunately
it’s far too broad an area mathematics to explain. So instead I’ll attempt to
explain a formula which actually made me question my life. I’m guessing you all
know what pi is (you know the 3.14 the ratio of the circumference to the
diameter of a circle), I’m not sure if you know what e (Euler’s number). This
is what it equals:
Which is approximately 2.72 and irrational like pi.
Also, I’m not sure if you’ll know what I is (as in the
irrational number), but it’s given by the square root of -1
So this is all well and good, but what’s exciting about
that. Well it’s when you combine e, i and pi you get interesting results. Be
prepared to be amazed.
Wait what? These seemingly unrelated number when combined in a very specific way equal -1. What?!
Yeah.
What’s your little
niece doing?
You know just living the hard life of a baby. Eating,
drinking, pooping, crying and sleeping. Also, not just pooing, but projectile
pooing at James’ mother, who needless to say, nearly screamed down. It was the
pure look of joy on my niece’s face compared to her nan’s reaction which I just
couldn’t but laugh at. Also, does anyone know why babies clothes have pockets?
I mean what is a baby going to need a pocket for? They can’t even coordinate
their own limbs yet, but they’ve got a handy place to store bits and pieces if
they so desire. But yeah, Elsie is a cutie, and I love being an Auntie.
Whould you like to be
Queen?
I’d like to be a princess, but what girl wouldn’t
want to be at some point in their life? I don’t think I would want to be a
Queen though – far too many efforts to give. James says he wants to be in the
band Queen on piano because Queen is the best band that has been, continues and
will ever be in the whole entire multi-verse. James just likes Queen a little
bit.

ReplyDelete(I don't know Japanese, but it is a Queen reference)
I'm currently studying for a communications systems exam, which means that I am very much aware that e to the j pi = -1. Also, that V/2(exp(jwt+Th)+exp(-(jwt+Th)))=V cos(wt+Th), which is very useful.
Is calling root -1 'j' an engineering thing or a your specific maths teacher thing?
DeleteI've noticed that we use j in physics and i in maths, here. Not sure why.
