Will We Understand Everything There Is To Know?

I had a discussion earlier on a thread on Facebook concerning the future of humanity. Some people asserted that we will eventually understand every mystery of the universe – but will we truly?

Right now the human race is growing rapidly, both in population and in technology; both are equally scary. Will we grow to the point where sustainability is not feasible? Will we not be able to feed ourselves? The opposite end holds technology; will we be able to combat the rising problems of…

Notes from a Defense

I wrote this while my friend and colleague Marcela Ewert presented her work at her Ph.D. defense. She's been doing a lot of really cool work about how Arctic microbes make their living despite the temperature and salinity extremes found in the sea ice and in the snow that rests on it. Here's a link to some of the work included in her dissertation.

Jargon note: exopolysaccharides, also known as…

Drake Made A Little List

Here's a little something about the Drake Equation, based on the song "I've Got a Little List" from Gilbert and Sullivan's "The Mikado" (here's a rather good modern take on it by Opera Australia.)

To answer those who ask why there's no aliens around

I've got a little list

I've got a little list

Of factors that when multiplied say whether they're not…

Sing a Song of Spaceflight

I've been working on lyrics to a Gilbert and Sullivan pastiche about the Drake Equation, but it's going a bit slowly. In the meantime, here is my version of "Wild Rover", which I sang at our local Chantey Sing a while back (the Chantey Sing is a get-together where people take turns leading the group in singing old sailors' work songs and other nautical music.) As I explained to the folks there, these days the exploration of unknown…

Tiny Submarine

As you may know, the oceans of Europa are sequestered underneath a layer of ice which is probably ten or twenty kilometers thick. This makes them a little tricky to access, especially given the limited resources available to a logistically-feasible lander. So I was intrigued by this article about a highly miniaturized submersible vehicle that wouldn't require much energy to transport…

Scatter, Adapt and Remember

Last month I went to see a talk by Annalee Newitz of about her new book, Scatter, Adapt and Remember. In the talk, she went over some of Earth's previous mass extinctions and their notable survivors, and discussed how humanity might manage to make it through the next one, whatever its cause might be.

It was an excellent talk and it inspired me to write the…

La pregunta milenaria.


La pregunta milenaria.

        Tal vez desde que el ser humano es consciente de su propia conciencia se ha preguntado si está solo en este lugar que se llama universo, misma pregunta que hasta nuestros días prevalece. La ciencia actual, es consciente de que esta pregunta tardara mucho o durará por siempre sin contestar, pero sin perder la esperanza en tener una respuesta para…

Panspermia, the which came first, the chicken or the egg question?

Below is a comment I wrote on

The problem with panspermia is that if life on Earth came from some other location in outer space, where did it come before that and so on with no end. Water, the universally…

Always make a back up of what you write

Have you ever had an untested idea, which could be right or wrong, written meticulously about it on a webpage article and then have that page replaced by another purportedly back dated?  It happened to me quite curiously.  I'm sure of it because the posting service the webpage provided allowed for the user to re-edit the comment which I did several times revisiting the page.  Then one day, after a couple of weeks I visited the webpage again to see whether anyone had commented on my post and…

Self fixing space suits

Space suits ought to have a liquid within for self sealing punctures from inside them just like the sealant I use in the wheel air chambers for my own motorbike's wheels.  I have not had a puncture in years. The sealant I use can handle pencil width holes.  I mean the sealant that you place inside a deflated new wheel chamber before inflating it, not the sealant used after a puncture. …

Mutual Inspiration

  I've been thinking a lot lately on how science and science fiction continually inspire each other. Science comes out with a new discovery that revolutionizes the way we view things, science fiction takes that idea and runs with it. The converse is true, too! Doubly so!

Some examples:

The Submarine - American inventor Simon Lake had been captivated by the idea of undersea travel and exploration ever since he read Jules Verne’s Twenty Thousand…
