A motorcycle is made, almost entirely, from empty space.


Me: Can we drive the bikes home ourselves?
Instructor: Sure, just... drive carefully.
Me: Sure thing
(5 minutes later)
Me: Woooooooo!!!

I can't wait to sit on a bike again! After conversations with several people "in the know", I've decided not to buy one in Denmark until I return from Australia, though. The money I'd save by buying it in autumn would be spent on storage and insurance anyhow.

Currently, my two biggest concerns about the trip are:

Selling my apartment
We had an estate agent out on wednesday, and he was confident he'd be able to sell it at full price. I hope he can do it quickly too! He was recomended to me because he sold another one in my area in three weeks. I've got my fingers crossed!

Finding, ferrying, and selling a bike in Oceania
I have no clue about the used motorcycle market in Adelaide.
I have no clue if it's convenient to ship it to New Zealand, or whether I should sell it and buy another one there.
I have no clue about the used motorcycle market in New Zealand.
I have no clue about how to sell it in either place.
I'm gonna mail my aussie contacts and see if they can help me get some information.

This thursday I'm playing a small private concert for a few people, showcasing some of the songs I've been working on. This is gonna be exciting, as most of them I haven't played for anyone before. At least one professional musician will be there, so I'm a bit nervous about it. I think I have some good material though, I just hope I can convince them of that!

This is an old one (like, decades old, but really well made considering.) but it is worth a watch anyway. Always nice to get your mind blown away by the awesomeness of the universe. This universe is so empty that the average amount of mass is pretty much zero. Funny that we find ourselves important when in reality we are no more than a byproduct of the big bang. One guy put it beautifully, except he was refferring to people, not mass:

It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.

For the nitpickers (Everyone else stay away, I'm about to go off on a rant!):
He made an error in his understanding of infinity though. Something less than one infinity can still be infinite in itself.
How many whole numbers exists (positive and negative)? An infinite amount.

How many whole positive numbers exist? Half as many as above, but still an infinite amount.
There are degrees of infinity, but all of them are still infinite. Bubbles of infinity within infinity.
The point still remains, though, that the average amount of mass in the universe for any given space is practically zero. Even inside the atoms of relatively dense material like uranium! This really makes my mind hurt, though, so I take some comfort in the fact that all the empty space is filled with energy. That way, I don't have to feel alone.
Hello, neutrino
