21st June 2010Sun DataI love information like this, and I love to see it manifested in the real world, right above my head. Dundee is just about on the same latitude as Perth ((The only adjustments needed to make this accurate for Perth would be to add a couple of minutes to all the times to accommodate for Perth's more westerly longitude.)), so this table is good enough for me. Check it out, and have a look at the data for where you live at various months. Today (as this is posted) in Perth, we will have 17 hours, 44 minutes and 36 seconds of ...

I hope life's not like that. I hope I'll always have a longer day to look forward to ((Or at least I hope to live without knowing that there are no longer days to come.)). Perhaps that hope is enough. I've decided that May is ...

10th June 2010MythfuckstersN.B. I could be completely misunderstanding this, and I could be completely wrong. I was drinking, after all. Mythbusters has frustrated me again. A few months ago I pointed out an inaccuracy in a previous episode. If my post was not sufficiently clear, my point was that a single car going 100 mph has double the total energy of 2 cars going at 50 mph, and not the same, as Jamie Hyneman had asserted. In an episode which I watched a few days ago, "Mythssion Control", I was delighted and rather pleased with myself when the program mentioned that 'the fans' had ...

About Wilf's Blog
I'm a mathematician, but apart from that, I'm a fairly normal guy. I used to write a blog - this blog. I write (wrote) about whatever is on my mind. It can get quite personal sometimes.
