“The firmness of a boiled egg can be adjusted at will through the cooking time. Some decisions are, however, irrevocable – a hard-boiled egg can never be reconverted into a soft-boiled one. There would be less annoyance at the breakfast table if we could simply switch back and forth between the different degrees of firmness of the egg.
Similar issues arise in the making of structural materials such as metals and alloys. The materials properties are set once and for all during production. This forces …

To me a solar cell is kind of like a Lamborghini: difficult to acquire, difficult to maintain, and unless you’re extremely lucky, only semi-functional. Today’s solar cells only convert a small percentage of the energy from the sun into electricity, and that’s before they get dirty.  “It’s challenging to get high efficiencies of conversion. For example, the basic single junction solar cell is fundamentally limited to an efficiency of 30 percent. So, if you made a perfect solar cell, the highest efficiency would be 30 percent. Currently, manufacturing cells with anything near that …

“Nature shows us a beauty that exceeds our imagination. On the other hand, it contains a strength that is sometimes frightening. The forms of nature are unique and cannot be reproduced. This endows them with mysterious beauty and makes them fascinating to us”.

I’m a big fan of sitting down in chairs, and like many Americans, I do it for hours at a time.  Don’t get me wrong, I don’t mind laying down or standing up, or sitting cross-legged on the floor – those positions are nice and everything. …

Remember watching the “clap on! clap off!” commercials back in the day? I always thought that the idea that you could turn out the lights by clapping was pretty fantastic.  The idea seemed so fantastic, it would cause me to clap my hands in excitement and plunge myself into darkness.  No, I’m kidding – I’ve actually never been in a situation where “clap on! clap off!” was installed, but I bet it made a lot of people’s lives better. When it’s tough to get up, it’s nice to be able to alter your environment without walking over …

Let’s assume for a moment that you are the Pope (because hey, this is the Internet and we can pretty much assume anything that suits our purposes, right?)  Okay, so let’s say your Holiness wants to head out of the Vatican and take a brief vacation at a villa that the Church happens to own on the Italian Sea Coast.  The ride out there shouldn’t be much of  problem danger-wise, because everybody knows that the “Popemobile” is bulletproof and “thicker than a 300 page novel” (Verrico).  But what if someone wants to cause trouble …

You don’t dance on a bee hive and sprint headlong into the house chased by a swarm of angry bees without developing a healthy respect for the sanctity of apidae habitat.  I didn’t mean to dance on the hive; I was only four years old and I had no idea it was even there until eighteen million bees erupted out of what I had thought was an innocuous stone-ringed mound of dirt.  The fact that such a small earthen bump could house that many insects is a testament to the …

Water.  The universal solvent. H2O.
It’s refreshing and highly necessary, but water in the wrong place at the wrong time can cause catastrophic problems in buildings.  It’s easy to envision the kind of damage inflicted by a flood, or by ten feet of snow on a roof designed to support six, or even by corrosion caused by salty ocean water at the seashore.  But the reason we wrap our buildings in fancy hi-tech paper and smear them with liquid waterproofing has more to do with the insidious effects of water vapor and intra-wall condensation.  …

Never have I felt even the slightest desire to slurp down an oyster.  Not once have I looked said bivalve in the eye*, so to speak, and been able to overcome my not inconsiderable revulsion long enough to taste one.  It seems however, that I’m in the minority; many of my dearest friends are completely mad for oysters and eat them in copious quantities whenever they can get their hands on them. 
I bring this up because tasting good (to other people, at least) is a positive characteristic of oysters.  Another positive …

 
Life is funny sometimes.  Just yesterday I was talking to a coworker about this crazy book I’m reading that I may have mentioned in a previous post called The Singularity is Near by Ray Kurzweil, in which the author posits that we are moving towards a world where our technology and biology fuse to become indistinguishable, and now today I’m writing about solar cells powered by bioluminescent jellyfish.  Let me also say that I’d much rather write about jellyfish than swim with them; they navigate the sea in creepy pulsing motions and some of them …

 
My apologies to bird lovers, but it can’t be denied that our feathered friends are somewhat lacking in gray matter.  To put it bluntly: birds are dumb.  They’re good at certain things like flying and pecking and saying “ca-caw!” but they have tiny brains.  The reason this becomes important in an architectural context is that you can’t reason with a bird.  You can’t say, “hey, maybe you should think about the fact that a lot of the openings you’re trying to fly into are actually filled with glass, and when you …
