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.
shift+scroll appears to scroll me back and forth in my browser history (Using FF).
I've always used alt+scroll for horizontal scrolling.

Edit: doesn't seem to work on the linked page

Yep it doesn't. So actually, on chrome, without an autoscroll extension, there is no way to scroll that page (apart from the with the right cursor button, which is way to slow to actually be valid) on a normal desktop pc. Happy new world.
shift + mousewheel works for me in chrome (windows 7 and osx)
you can click in the scroll bar. It is fast enough. Better than holding the right button.
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! :)

Sorry you have a shitty computer, or OS, or both.
And the main reason why we have web standards is that it should not matter how "shitty" your device is to access content on the web comfortably.
This web page uses a native OS scroll. Nothing to do with web standards.
I think it was designed for a Macbook's excellent trackpad. That said, I can see how it would be really difficult to scroll without one.
This broke the "two finger right sweep" to return to the previous page (HN). I had to touch the back button on Safari. Felt horrible about that ...
I think that is Apple's mistake. I have to go into settings and turn the two finger pref/next pages to three, three finger spaces swipe to four just to avoid the problem you described.

And why the hell don't they enable "tab to all controls" by default?

Yes, still, I only "use" this feature by mistake.

especially because it's too easy to make it when scrolling up

Using a trackpad would mean I'm hunched over my laptop trying to destroy my back and neck further than I already have. Designing websites specifically for anti-ergonomic use cases is unwise.
Designing for one thing that's really good in a world of things that are average, isn't the best strategy. Reminds me of "Designed for IE6" and look where that got us.
I just clicked and held the middle mouse button to move to the right smoothly.
I kind of felt that the slowness of using the right arrow to scroll was kind of the point. Even holding it down, you're moving significantly faster than light. And it still takes an age to get anywhere.
My scroll wheel has sideway tilt.

However I just used the navigation icons on the top.

There are no navigation icons showing for me: FireFox 11.0
It is actually far too fast, several times the speed of light. If you really wanted to realize how vast and empty space is, you should make it scroll slower.
I think sticking to the speed of light for scrolling transitions would put things even more into perspective (though make the content a little harder to reach haha).
But if you make it realistic - have you thought of the actual size of those letters?
shift + scroll wheel works okay, but really, it should have been scrolling vertically. horizontal scrolling doesn't really add anything to the site but inconvenience for the viewer.
I just held down my right arrow key.
Try tilting your mouse 90 degrees then scroll the wheel towards the left.
Middle-click on empty space, move the mouse slightly right (or further, depending on the desired speed).
Annoying but I've just noticed there are icons to 'quick scroll'
The icons are the planetary symbols - e.g. the "female" symbol for Venus, the "male" symbol for Mars, and so on.
This is very cool - I love demonstrations like this that show the scale of incomprehensible scales. It's always fascinating.
I agree. This was a beautiful illustration of our solar system. I especially liked the running narrative. ;-)
But this should not use the subjunctive, because he has indeed drawn an image using the scale of the Moon being one pixel wide. This shows it's possible, and hence the subjunctive is inappropriate.
That's not really correct. Even if we assume that this is no longer a hypothetical/counterfactual case, then the correct grammar is to use the present tense ("This is the moon as one pixel"). But, in this case, it still is counterfactual. This is really short for "If the moon were only [the size of] a single pixel", a statement which we know is not correct.

You're probably confusing this with the rule surrounding verifiable facts (ie, "I asked John if he was happy").

(comment deleted)
Quoting from the Wikipedia page:

    Subjunctive forms of verbs are typically used to
    express various states of unreality such as wish,
    emotion, possibility, judgment, opinion, necessity,
    or action that has not yet occurred.
The action has occurred, it is not an unreality. It seems to me that using the subjunctive would be inappropriate.

And yes, perhaps using the present tense would be more appropriate. Certainly I would have used something like:

    The solar system plotted on a scale where the Moon is one pixel.
My comment still stands - the subjunctive is inappropriate. Saying it should be still something else does not make that less true.

<Shrug /> It's the interwebs, people will write what they like, and declare that nothing is right, and nothing is wrong, it's all OK. In that case telling someone to use the subjunctive seems doubly inappropriate.

https://xkcd.com/386/

English is not my native language, but using "was" sounds pretty weird to me. In latin languages, when a sentence starts with "if" and the verb is in a past tense form, it must be the subjunctive form of the past tense. I remember in primary school they teach the past of the subjunctive with "if" before all the pronouns. Don't know how they teach the past of the subjunctive in English though.
I tried to use the scrollbar to scroll but I never landed on anything but empty space. While it did perfectly show off the vastness and emptiness of the universe, it probably was not the intended result.
Quote: "Sorry, Humanity," says Evolution. "What with all the jaguars trying to eat you, the parasites in your fur, and the never-ending need for a decent steak, I was a little busy. I didn’t exactly have time to come up with a way to conceive of vast stretches of nothingness."
I feel like it's not the vastness we can't comprehend, it's the relation between such "tiny" planets and such big distances that's hard to grasp. You can't zoom out or else you stop seeing the planets, you can't zoom in or else the map gets even larger.
To wrap my mind around it, I try to imagine astronomical objects as everyday objects. For example, if Sun was a base-ball in my hand, the earth would be a mote of dust some throwable distance away. My favorite one is: if Sun was the size of a grain of sand, the nearest start would be another grain of sand 30 kms away!
I cheated :)
I used the warp drive console at the top. "Engage"
Nit: kM -> km; meters are abbreviated 'm', usually.
Since this story seems to be nit territory, another one: 'm' is not an abbreviation, but a symbol. That's why you don't write a dot after it.
1. Nice.

2. Obligatory question - how many working hours were just lost?

3. Why on earth would you use capital M for meters? I really hope I will not look really dumb in a minute, but I immediately knew something was wrong, but it actually took my quite some time to recognize it.

"Why on earth..." I see what you did there.

But seriously, I don't think I've ever heard of using M for meters.

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

Great link! That's my goto for correcting people's units problems. Such a fantastic resource.
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 "imperial sucks" and "imperial is clearly inferior."

To me, I only see using imperial units as an advantage. As Americans, the metric system is already hammered into our heads in grammar school anyways. Some might see it as Americans being uninformed or accustomed to antiquated methods, but I see it as Americans being able to speak two languages (at least the Americans I'm most familiar with).

"Imperial" in USA is actually not the same as "imperial" in the UK. There are slight differences between all units, but a significant difference with volume. A US gallon and a UK gallon are different by about 25%.

The US "imperial" vs UK "imerial" is why during WW2 the Allies (USA, UK, France etc.) used metric. Cause there's only one cenimeter. (Very important when you're making bullets)./

I think that most common infantry bullets in allied side were .30in (7.62mm) and .45in (11.43mm) and to some degree 9mm. So yes, to some extent you are right, but note that caliber is inch based
I only see using imperial units as an advantage

Out of genuine curiosity, what's the advantage from your point of view, other than being able to communicate to other people who use the same system, at the cost of not being understood by everyone else?

(What I heard in the UK during the supermarket transition to metric a decade ago: imperial uses fractions, which is a useful to grasp for learning children, etc. But I'm surely misquoting so don't worry about this argument)

I am asking because I only come across the imperial system when watching Mythbusters or reading a book about the Space Shuttle, or someone tells me their weight in stones, which always leaves me rather puzzled.

This is just out of curiosity, I'm not trying to work anyone up.

> Out of genuine curiosity, what's the advantage from your point of view, other than being able to communicate to other people who use the same system, at the cost of not being understood by everyone else?

The metric system is 10 based, which makes it trivial to measure and convert: 1000mm = 100cm = 1m. This becomes even more important when you are talking about volume or any ^3 dimension.

I have lived in the US for 15 years and even today, I'm unable to convert fl oz. to any kind of mass measure without getting a headache along the way.

> Out of genuine curiosity, what's the advantage from your point of view, other than being able to communicate to other people who use the same system, at the cost of not being understood by everyone else?

What other advantage, you ask? Well, I'd say that there is none. I was merely trying to convey that being fluent in both imperial and metric is better than being fluent in only metric. As long as it doesn't hurt me (which imperial doesn't) the more skill-sets I have, the better!

I hope you better see where I'm coming from now. You didn't work me up though, and I also didn't mean to work anyone up either. :)

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.

  > the relationship between mass, volume and length is trivially easy to understand.
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.)

> In the US, a pint's a pound the world around

Having been born and raised in the US, I have never heard this before.

Presumably you are referring to a pint of water?

(Then again we never learned pints anyway, so meh)

a pint's a pound the world around

I always wondered if butter was the basis for standard units. There's something rather wonderful about that idea to me.

Perhaps they sort-of knew that both l (lower-case L) and L were acceptable for litres and thought case-insensitivity applies to all metric units.
The sole advantages of imperial units over metric units is that they are easier and faster to say.

50 miles is a ton less syllables than 50 'kilometers' an inch is much easier to say than '2 centimetres'

What would immensely improve the metric system would be recognised, single-syllable slang words for every measurement unit. A lot of native-metric-english speakers try, they say 'mil' for millilitres, they say 'kays' for kilometres, but you're still left with either awkward decimal points or excessive syllables.

I am 'one point eight three metres' tall, or 'one hundred and eighty three centimetres'. Or I am 'six feet'. Guess which gets used most?

The curse of the metric is the endless tongue-twisters.

Compare equivalent accuracy. "one hundred and eighty three centimetres" is not noticeably more complex than "five feet seven and a half inches". And you have the option of "eighteen decimeters" if that's the level of accuracy you want - try inventing an intermediate unit on the fly with imperial.
But you wouldn't go down to a half-inch, and there is a shortcut - '5 foot 7'. I'm not referring to accurate measurements, but the sort of day-to-day, rounded off measurements that pepper our daily speech.

If I said a decimeter to any of my friends, they would have no idea what I was talking about.

> there is a shortcut - '5 foot 7'

You can say "1 meter 83", and people do.

> If I said a decimeter to any of my friends, they would have no idea what I was talking about.

Well, mine would - and any who didn't could easily figure it out. If you're willing to memorize all the random names the imperial units have, you can afford to remember "deci".

Since we're talking about astronomy, both imperial and metric units are "wrong" and domain specific units should be used instead.

Unit of length should be astronomical units (abbrev. au, formerly AU), the mean distance between earth and the sun. If talking about distances in stellar scale, it should be parsec ("parallax second"), the distance from which an 1 au object can be seen at 1 arc second apparent size (and sin x = x is assumed because x is small).

Unit of mass is usually solar masses. In some special cases earth masses or jupiter masses.

Unit of density is either number of atoms in m^3 or other big volume when talking about interstellar medium or kg/m^3 when talking about planets or stars.

Unit of time is usually measured in years.

When you use solar masses, years and astronomical units, Kepler's 3rd law is reduced to: (m1+m2)period^2 = semi-major-axis^3 and the gravitational constant G = 4 * pi^2 (and thus it's cancelled out from G(m1+m2) * P^2 = 4 * pi^2 * a^3).

I definitely would have liked to see the distance in astronomical units and a verbal description of the distance ie. (5 million kilometers, not 5000000 km). Humans are really bad at understanding big numbers, any means of helping to understand that would be useful.

Looks like the author changed it to 'km'.
The units in the intro screen are still kM, though.
Nice way to see that my computer monitor is very dirty.
Really neat. I enjoyed scrolling to earth. After that it became painful.

Thankfully, the solution was easy:

Open Chrome Inspector Console:

$('.essay').css({ left: '20px', marginBottom: '15px', maxWidth: '600px', position: 'relative' });

$('#bigspace').css('left','inherit');

I just used the shortcut buttons at the top. Your solution is more fun. :)
Neat comparison. But it would be nice if there was something on the initial screen that suggested scrolling. I just thought that a black page locked Safari.
I had to come read the comments to figure out why I was just seeing a black screen that wasn't scrollable. Sideways scrolling? Really? There's a reason no one uses it.
We usually put lengths along an X axis when graphing, I believe this is why horizontal scrolling was used.

We also tend to think of our planets in order from left to right from the sun.

If this was about ocean depth, vertical scrolling might be more analogous.

But its all subjective of course.

I have previously wandered along the scale model of the solar system on the St Kilda beach in Melbourne. Yesterday I did the same with the scale model in Bonn. In both cases I only got as far as Uranus.

It was interesting along the way to verify Kepler's relationship between the orbital period and the distance. Saturn takes about 30 years to go around, and is about 30^(2/3) ~ 10 times the distance. Jupiter takes about 12 years to go around and is about 12^(2/3) ~ 5.2 the distance.

Standing by the plinth with the Earth and the Moon, looking back at the Sun, then forward to Mars, and not being able to see Jupiter really does give a true sense of the scale.

Not to diminish this effort, but getting out and walking the distances make a difference.

When I was a kid I wanted to make such a scale model. I think I calculated sizes with Earth = 1 inch, and the distances made the mind boggle. Using a pixel as a unit of measure was pure genius, it makes the model so much more manageable without detracting from the overall grand scale.
There's a scale model of the solar system spread out over hundreds of kilometres across New South Wales, with the Sun at Siding Spring Observatory.
If the moon WERE only 1 pixel...you know...because it's not. :)

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.

I can imagine a dead pixel would be like your spaceship.
dead pixel,

its stars are specks

of dust

You haven't been compelled to touch the dust on your monitor until you thought they were stars.
And then you realize the dust is made of stars...
And stars, dust. And we are all star-stuff, each of us.

None of the ancestor comments are in the spirit of HN. They're much closer to the kind of comments found on Reddit.

See:

"The most important principle on HN, though, is to make thoughtful comments. Thoughtful in both senses: both civil and substantial.

The test for substance is a lot like it is for links. Does your comment teach us anything?

All of that dust was stars, once :)
Thanks for including Pluto (technically not a planet but still one in my mind).
If one's going to include Pluto it would be nice to have Ceres, which was also cruelly stripped of its planetary status.
I remember Bill Nye doing this in one episode. He had the earth as a golf ball, I think? He was running around a soccer field showing the planets. And he drove miles away to show where Pluto would be.

Edit: this episode! https://www.youtube.com/watch?v=gRIVwGwdxI8#t=250

Edit2: nope, this one (guess he liked this trick lol) https://www.youtube.com/watch?v=A_OWnlS56rE#t=325 Pluto is only 100 meters away, but Alpha Centauri is 700 km away!

Actually, in that one, the earth was the size of the ball of a ball-point pen.

The sun was the size of a soccer ball.

Nicely done! I've always wanted to build something like this, and have never gotten around to it. I can't imagine it would have ended up as good as this.
At the 10 million km mark, it says "that was about 10 million kM (621310 mi) just now. Either "mi" is a unit other than miles or the math is wrong (10 million km is about 6.2 million miles).

I'm not a native speaker, but I had the impression this shift to "were" happens less in the UK than in the US. Is that so?
I speak British English and it's more a matter of register for me. If I'm writing something formal I'll use the subjunctive, if I'm talking to friends I'll just stick with the indicative.

If I saw someone write "it is necessary that he goes" in a paper it would stick out as strange to me, likewise if I heard someone say "it is necessary that he go" it would sound overly formal and a bit stilted.

So really, you can use either and be understood perfectly well. It only seems to annoy prescriptivists, and I would say one has a moral obligation to annoy prescriptivists anyway.

> one has a moral obligation to annoy prescriptivists anyway

And that's a cause I can really get behind.

> one has a moral obligation to annoy prescriptivists anyway.

Challenge accepted! (See above.)

"was" sounds correct to me (US), but everyone learns a slightly different language model.
somewhere along the way when I was young I learned "were" and I almost wish I hadn't haha. here in the northeast/midatlantic the majority of people use "was". it's only a slight nuisance now :) and i'm not even a native speaker. can't imagine how english teachers and actual writers and such feel about it.
Use of the subjunctive mood is slowly declining, especially in the UK. We often smooth out the difference by inserting a "should" or "might". E.g. "It's important that you (should) be on time."
Yes! One of my pet peeves (philosophy major).
Peeves make TERRIBLE pets. Set them free; you'll be glad you did.
They came back, so they're truly mine.
Descriptive linguistics doesn't mean "whatever anyone says is correct and it should go." This ain't 'nam, there are rules, and you can still run afoul of them. The basic tenet of descriptivism is that, as people who study linguistic patterns as a science, we can't make a value judgment about a certain set of rules or what a person "should use". However, I think it's generally accepted that we try to strive for some common set of agreed upon linguistic rules when trying to formally communicate on the Internet, and many would claim that the subjunctive mood would fall into that.

I saw a really good write-up about this before and wish I could find it :(

EDIT: This one's not it, but it's very similar: http://motivatedgrammar.wordpress.com/2011/11/07/descriptivi...

No disrespect intended, but this is yet another example of the inverse correlation between grammatical knowledge and enthusiasm for pouncing on grammar mistakes.

In Standard English, this use of the subjunctive mood is optional, not required.
