Are you kidding me? Sideways scroll with no way to use my scroll wheel? It's choppy and unreadable scrolling using the scrollbar, and using the right arrow is just too slow.

Just a hint shift+scroll wheel in a lot of cases will scroll horizontally.

What the... Something is wrong with me. I've been paid to work with computers for about 16 years, and somehow I did not know this. Heh.

Thank you! :)

Somewhere between Jupiter and Saturn, I had to resort to $(".essay").each(function(i){console.log($(this).text())}); to read the fun little text snippets. I like how it got fairly philosophical—everything eventually turns to philosophy if you are stranded out in space. Thanks for putting this together; it was a nice take on the perspective of our universe.

And here's the output of that command for those interested:

As I was scrolling through I started to notice a really nice, subtle star background pattern that wasn't moving. I thought that was a really nice touch. And then I touched my monitor and, turns out, it was just dust. There's a metaphor there but I have no idea what it is.

3. Correct, and not knowing anything about the author I would venture that the reason is that he uses imperial in his everyday life, and thus it has been a concession to the wider world to do this in metric, for which I am grateful :-) Citation for "lowercase m for meters": http://physics.nist.gov/Pubs/SP811/sec06.html

I'm American, so I use imperial units in my everyday life. I'm also a (bio)chemist, so I do use metric units about as often as I do imperial units. While I might be slightly biased ("M" is molarity gosh dangit), I don't think I would confuse "M" for "meters (m)" simply because I use imperial units in my everyday life. I bring this up simply because I've seen a few comments over the past few days to the tone of "imper…

There is at least one reason for me that metric is vastly superior as a way to describe the world than the UK or US version of Imperial: the relationship between mass, volume and length is trivially easy to understand.

A small cube of 1cm represents 1cm³, which is also 1mL which is also 1g of water.

So a cube just 10cm across contains 1000cm³, or exactly 1 Litre and weighs exactly 1kg (of water).

It's easy to grasps and visually/physically see the relationship between these fundamental units.

Relationships to other fundamental units is also greatly simplified: the Newton is the mount of force needed to accelerate 1kg to 1m/s²; the Joule is the amount of energy needed to move 1kg by 1m or moving 1A through 1Ω, ...

Not all units are so cleanly expressed in terms of other units, but, at least for the everyday ones, the kg, Litre and metre, the relationship is easy to understand.

To me, Imperial measurements are confusing. It's even worse considering how food recipes are described in terms of cups (a unit of volume) rather than weight.

Getting a cup of dry pasta is not going to give me the same amount of pasta depending on the shape of the pasta I'm trying to cook. Try getting a cup of spaghetti.

Imperial units also have a simple relationship between mass and volume. In the US, a pint's a pound the world around, and in the world around the US, a pint of water is a pound and a quarter, and in some of those places that rhymes.

(One fluid ounce — either kind — of water weights approximately one ounce.)

Don't know if I should be embarrassed or proud that I manually scrolled all the way past Uranus before giving up!
