The Most Brilliant Science Graphic I Have Ever Seen January 5, 2012

The below link takes you to an absolutely fantastic interactive demonstration of the relative size of everything. Everything. Stop reading this and go look at it, when it finishes loading, move the blue blob at the bottom of the screen left and right.

The Relative_scale_of_everything

The raw web link is:


The web page says scale_of_the_universe but it should be relative_scale_of_everything_in_the_universe. Did you go look at it? NO!?! If it’s because you have seen it before then fair enough – otherwise stop reading this stupid blog and Look At It! NOW! GO ON!!!

Yes, I do think it is good.

I have to thank Neil Chandler for his tweet about this web page which led me to look at it. Neil and I talked about relative sizes of things in the pub towards the end of last year, in one of the Oracle London Beers sessions. I think it was Neil himself who suggested we should convert MB, GB and TB into time to get a real feel for the size of data we are talking about, you know, when we chuck the phrases GB and TB around with abandon. Think of 1KB as a second. A small amount of time for what is now regarded as a small amount of data – This blog so far is around 1.2kb of letters. Given this scale:

1KB = 1 second. About the time it takes to blink 5, possibly 6 times, as fast as you can.
1MB = Just under 17 minutes. Time enough to cook fish fingers and chips from scratch.
1GB = 11 and a half days. 1KB->1GB is 1 second -> 1.5 weeks.
1TB = Just under 32 years. Yes, from birth to old enough to see your first returning computer fad.
1PB = pretty much all of known human history, cave paintings and Egyptian pyramids excepting, as the Phoenicians invented writing about 1150BC ago.

The wonderful thing about the web page this blog is about is that you can scan in and out and see the relative sizes of things, step by step, nice and slowly. Like how small our sun is compared to proper big ones and how the Earth is maybe not quite as small compared to Saturn as you thought. At the other end of the scale, how small a HIV virus is and how it compares to the pits in a CD and the tiniest of transistors on a silicon chip. I’m particularly struck by the size of DNA compared to a human red blood cell, as in how relatively large DNA is. Red blood cells are pretty big cells and yet all human cells (except, ahem, red blood cells) have 3.2 billion letters of DNA in each and every one of them. That’s some packaging, as cells have a lot of other stuff in there too.
{NB, do remember that the zooming in and out is logarithmic and not linear, so things that are close to each other in the graphic are more different than first appears, especially when the image becomes large and in effect covers a wide part of the screen}

Down at the sub-atomic scale there are a fair number of gaps, where one graphic is pretty much off the scale before the next one resolves from a dot to anything discernable, but that is what it’s like down that end of things. Besides. It’s so small it’s hard to “look around” as there is nothing small enough (like, lightwaves went by several orders of magnitude ago) to look around with.

My one criticism? It’s a shame Blue Whale did not make it into the show :-)

I actually had flashbacks looking at this web page. I remember, back in the mid-70′s I think, going to the cinema. Back then, you still had ‘B’ shows, a short film, cartoon or something before the main event. I no longer have a clue what the main event was, but the ‘B’ movie fascinated me. I think it started with a boy fishing next to a pond and it zoomed in to a mosquito on his arm, then into the skin and through the layers of tissue to blood vessels, to a blood cell… you get the idea, eventually to an atom. Some of the “zooming in” where it swapped between real footage was poor but it was 1970 or so and we knew no better. It then quickly zoomed back out to the boy, then to an aerial view of the field, out to birds-eye… satellite-like…the earth… solar system… I think it stopped at milky way. I wish I knew what that documentary was called or how to find it on the web…

{Update, see comments. Someone links to the film. I know I looked for this film a few years back and I did have a quick look again before I posted this message. I did not immediately find it but someone else did, in 10 seconds via Google. Shows how rubbish I am at using web searches…}
