Precisely.
This is not my first attempt at a blog, last year, when I went to Canada/USA Mathcamp, I tried to keep up a blog for the 4 weeks I was there, and I was like HOLY SMOKES I FEEL MOTIVATED TO DO MY FIRST POST and then after that I went into a bit of decline, failing to keep a regular schedule. In the end I started writing longer posts to make up for my lack of a posting schedule (and lack of pictures in previous posts). After I returned to Singapore I just failed a lot and nothing happened.
In one of the posts I did mention something about Hadamard matrices, and somebody (whom I looked up on the internets and found that he was a professor) offered to give me some materials on Hadamard matrices, and then I replied a few days later. Apparently I was too slow because he didnt reply. Q_Q makes me sad. I feel like I've wasted some kind of opportunity. [In any case I have tagged this post with lots of relevant tags so if you are anywhere out there, Mr Will Orrick please do drop by :) ]
My blog is still fail. I seem to run out of motivation quickly when trying to write a blog. For some reason all I feel like doing is the occasional random post on something I happen to think of.
Oh, and I applied for the Integrated Boarding Programme, so with any luck I'll be in boarding school (looking for one more person to share a 4-person room with).
Swine flu was kinda scary at first, but now it seems to have calmed down a bit, hopefully nothing else will happen.

Arthur Ganson is awesome. A must watch ^^. Personally I like the one with the cat and the chair.
I run out of motivation here.

To me blog is like more for interesting stuff or for venting out sorrows and anger. Well, you can see me spamming my wordpress :P
ReplyDeleteSo sad D:
ReplyDeleteI prefer writing about stuff that is interesting and happy yay, though I might complain occasionally.
Unfortunately interesting stuff dosen't happen that often.
Hi,
ReplyDeleteI just found your blog again. Sorry for not checking back at your old blog. That was rather inconsiderate of me.
I remember you had asked about the proof that Hadamard matrices come only in sizes 1, 2, or multiples of 4. Did you ever work that one out?
There have been a few books written about Hadamard matrices, but I would imagine only the most recent ones are still in print, and they may not be the best starting points anyway. You've seen the Wikipedia article on Hadamard matrices? If not, you might take a look. I'm not very fond of that article, despite having contributed some things to it. (Not that it's bad, just a little bit disjointed. Also rather incomplete.) Mathworld has a decent article, but it's also not terribly complete.
There's a construction due to Paley that, in some sense, is our richest source of Hadamard matrices. Wikipedia has an article on that too. I included a couple of detailed examples in that article in the hope that a mathematically motivated, but not necessarily professional reader would be able to follow it. If you're still interested in following this up, have a look. I'd be very interested in any suggestions about how to make the article more readable.
There are some other nice little puzzles about Hadamard matrices that I could suggest, if you think you might be interested.
