What’s it like to be a solid rocket booster? aimee whitcroft Mar 25


A question, no doubt, which has kept many of awake over those long, long nights.

And now, we have people to the rescue!

From the upcoming Special Edition Ascent: Commemorating Space Shuttle DVD/BluRay by NASA/Glenn a movie from the point of view of the Solid Rocket Booster with sound mixing and enhancement done by the folks at Skywalker Sound. The sound is all from the camera microphones and not fake or replaced with foley artist sound. The Skywalker sound folks just helped bring it out and make it more audible.

Sadly, and because we’re still dealing with the piffly not-entirely-realistically-modern internet, it can’t give you an idea of the temperature differentials (which would have killed you anyway, without the right gear*) or the utterly insane G-forces at play, but hell, it’s a start!

Now, hook up your best pair of headphones and enjoy the ride…

And then watch it again, but this time, only listening to it. It gets amazingly eery a coupla minutes in.


* And even then, I’m not sure…


Massive HT to the Terrible Fenemor for pointing this out to me this morning.

Stunning science imagery Pt I aimee whitcroft Feb 03


Presents for your visual systems today… And we’ll be presenting two different people who’re merging science and visuals in new, and quite effective, ways.

xkcd: Fourier

xkcd: Fourier

I know I have a previous post somewhere (probably on my old blog) about engineering photos as well, but I thought I’d start afresh.

So, first up (because I saw it first), is this fantastic imagery, generated by acoustics engineer Mark Fischer (article here).

Fourier Transform (FT) maths is normally used to analyse sound.  It has its limitations, however: it doesn’t handle more complex sounds very well, often turning elements into noise.

And a perfect example of these kind of complex sounds are the calls of whales and dolphins.  And birds.  So Fischer has begun using another method: wavelets.  This is great – not only does it give a far more accurate and detailed map of the sounds/elements in the calls, but the pictures are perdy.  Seriously.  So perdy, in fact, that he’s able to sell them as art.

Hooray for interdisciplinarianism.

Up next is this.  Again, one of those almost ‘duh’ moments, except you have to be a mathematician, a photograher, and a little bit on the artsy side to have the thought.

Still, it works.  Nikki Graziano overlays graphs and their corresponsing questions onto photographs she’s taken which illustrate the equation/graph in question.  Of course, the cool thing about being a mathematician is that she doesn’t need to draw the graph and then prowl the streets looking for an analogous image – instead, she’s able to take photos and then fit the maths to them.

Interesting stuff.  I continue to be unimpressed that I’m not one of Nature’s mathematicians…
