moonvilla concept

157617

Here are 3 fun designs (via notcot):

-Tree Trunk Garden House.
- Beijing Noodle Restaurant design
- Moonvilla Concept (as seen above. more pictures)

The Moonvilla has an outer shell/screen that revolves with the sun to regulate the climate inside. Neat. Although I wouldn’t want to be around when the motor is on the blink. Having said that, there is cleverly a little underground level built into the design.

There are no stairs. Due to the lack of gravity on the moon, people can leap from floor to floor!

and now back to our home…

The American Museum of Natural History has prepared a video in the vein of Charles & Ray Eames’ Powers of Ten which lets you see our planet’s size relative to the universe. The Museum’s is scientifically accurate — based on data compiled by their astrophysicists.

It’s nice to watch in full screen (at high quality, if your computer can handle it [mine can't!]).

there’s no ice cream on the moon

Alan Bean, of Apollo 12, on returning to Earth:

Since that time I have not complained about the weather one single time. I’m glad there is weather. I’ve not complained about traffic. I’m glad there’s people around. One of the things I did when I got home, I went down to shopping centres, and I’d just go around there, get an ice cream cone or something and just watch the people go by, and think “Boy, we’re lucky to be here, why do people complain about the Earth?”. We are living in the garden of Eden!

I just saw the documentary In the Shadow of the Moon (2007) on TV. In my experience it’s rare to see the Apollo astronauts’ stories so personally and compellingly told as in this film. They, as talking heads, tell you the little details that in other contexts are crowded out in favour of cliché and sensationalism (ironically lessening the excitement), but whose inclusion here make the movie special.

The documentary also makes use of materials and footage that was unreleased for 30 years. There’s some cracking imagery.

The movie seems to be online in its entirety on YouTube.

Notes from a Hadron Collider

The author Bill Bryson has an article in the Times’ science supplement to explain where the CERN team currently are with the Large Hadron Collider.

Three other mighty detectors are arrayed around the LHC perimeter, all of them complex and wonderful and calibrated to find various puffs of quantum liveliness. It is hard not to be struck by the inverse relationship between the tininess of what the physicists are looking for and the costly massiveness of the equipment needed to find it. I ask Virdee if it can possibly be worth investing so much money and brainpower in a search for obscure and evanescent particles.

He smiles, but instantly says: “Yes. Undoubtedly. You know, a little over a century ago when the electron was discovered nobody saw it as having any practical applications. It was just an interesting addition to the sum of human knowledge. But that bit of knowledge was what made the electronics industry possible. Imagine a world without electronics. It is impossible to know where discoveries we make here might lead, but you can be certain that one day people will be glad we made the effort.”

a glorious doom

What a thrilling concept theoretical physicist/cosmologist Paul Davies entertains: A no-going-back approach to Mars exploration.

A round trip to Mars would be demanding of many resources and put astronauts in twice as much mortal danger (probably more than twice — taking off from barren Mars would be no walk in the park) than if they only had to risk their lives once, on the way over. Therefore: send people to live on Mars until they die.

I would envisage probably four people would go in the first instance. But a one-way mission to Mars would not just be a one-off exercise. They would be trailblazers. It would be the first step to establishing a permanent human presence on another world. Although they would go without the expectation of returning, they would have the expectation that sooner or later they would be joined by others and that this Mars base would grow and eventually become a permanent Mars colony that might take hundreds of years to establish.

Who would be so unhinged, who would have supportive enough underpants, to do such a thing? Well it’s hardly unheard of, argues Davies. Take those who first explored antarctica.

These people often went knowing that there was a high probability that they would not come back, and that if they didn’t come back, they were going to their deaths. I’m not suggesting that going to Mars necessarily means an instant death, but it may mean a premature death, it may mean your life expectancy is shortened by a little bit. But as I said, people attempt that risk in all sorts of other walks of life.

And what I have in mind is not just four miserable people sitting around on the martian surface waiting to die, (laughter) but that they would actually be doing useful job work. Of course, your accommodations would be cramped. People have said to me: it would be horrible living in these conditions. And my answer is, it’s not as bad as Guantanamo Bay.

It’s not as bad as Guantanamo Bay, folks!

How to fund such an ongoing operation, anyway? Selling television rights is one idea Davies reckons would be highly lucritive:

How do we pay for all of this? Given that NASA’s not going to do this, I think that ultimately this would have to be an international collaboration or some sort of commercial venture. Nobody is going to set up a permanent presence on Mars without having some sort of commercial arrangement. The discoveries that would be made by people working on Mars would have to be patented, there would have to be a cash flow that would pay for this. Imagine the TV rights – think of what people pay for football rights – I mean, huge sums of money. So a spectacular like this, a real life soap opera from another planet, I would think would be worth a lot of money. We can have more ambitious ideas about Mars Funds and long-term land titles and so on. Instead of selling worthless bits of land on Earth, with a time scale of some decades for their use, we’d have to extend that to some centuries. But there would be people prepared to do that.

Imagine the psychological pressure — “get good ratings or you’re dead!”. Ok so it would probably never come to that. But I like Davies’ ideas. You can read more of them at astrobio (via neatorama).

This story of such a large-scale challenge appeals to me at the moment especially because I’ve been trying to think of a way to put myself on a career trajectory that could lead to exciting places, even if things to start modestly.

I suppose if I were to try to draw a lesson from the above article it would be that grand challenges sometimes demand immodest beginnings, daring ideas… and balls so massive that only zero-gravity would make them managable.

NASA melts Martian ice with warmth of heart

If that title was unexpectedly romantic then it was perfect.

NASA, it transpires, has for the past 50 years enlisted not just calculating concept artists in its ranks, but also artists employed to document the human experience that is attached to NASA’s
monumental missions.

John Walker of the National Gallery of Art quickly agreed to help, arguing that artists could “probe for the inner meaning and emotional impact of events which may change the destiny of our race.”

The results of this stunning collaboration between scientists and artists are collected in NASA/ART: 50 Years of Exploration, by James Dean and Bertram Ulrich, published by Abrams Books.

alone

David Stone titled this painting “A Handful of Emeralds” after hearing astronaut John Young describe the stars as “a handful of emeralds thrown across the sky.” He tried to express the magnificent, revolutionary solitude experienced by an astronaut adrift in a manned maneuvering unit, staring out at the void of space.

Discover magazine has a selection of images from the book, with descriptions.

Thousands of years ago, Mars and Earth probably presented similar primative environments so if life existed on earth, then we can legitimately consider the hypothesis that it could also have developed on Mars.

making space perceptible

v21-580x435

The above picture demonstrates in colour the amount of detail that is now attainable with the upgraded Hubble telescope (right) by comparison with what it was capable of before (left). Both images depict the Butterfly Nebula. More comparison pictures at universetoday.

Human eyes are not capable of appreciating the many shades of light of which images taken of Space are composed. That’s why photos taken by telescopes, such as the recently upgraded Hubble space telescope, are literally photoshopped before they reach the press and the public eye — to convert the invisible shades of light to colours within the humanly-perceptible spectrum.

Slate has reprised an article from 2005 in which this process is described:

First, they put the image into a file format appropriate for media. That means that the data from the FITS files, which show a range of about 65,000 shades of grey, must be squeezed into a standard JPEG or TIFF file, with only 256 shades. This process is counterintuitively called “stretching” the data and must be done carefully to preserve important features and enhance details in the finished product.

Then each grey-scale image is assigned a color. In reality, each shot already represents a color—the wavelength of light captured by the filter when that picture was taken. But in some cases the images represent colors that we wouldn’t be able to see. (The Spitzer, for example, registers the infrared spectrum.) To create a composite image that has the full range of colors seen by the human eye, an astronomer picks one image and makes it red, picks another and makes it blue, and completes the set by coloring a third image green. When he overlays the three images, one on top of the other, they produce a full-color picture. (Televisions and computer monitors create color in the same way.)

Venus the Spoilsport

Systemic (a blog mostly concerned with extrasolar planets) has a nice entry which charts how our perception of Venus has changed in recent history.

Venus used to be thought possibly habitable, if extremely humid. Greg of Systemic posts the opening paragraph of Ray Bradbury’s 1950 short story The Long Rain, which paints an imagined picture of Venus:

The rain continued. It was a hard rain, a perpetual rain, a sweating and steaming rain; it was a mizzle, a downpour, a fountain, a whipping at the eyes, an undertow at the ankles; it was a rain to drown all rains and the memory of rains. It came by the pound and the ton, it hacked at the jungle and cut the trees like scissors and shaved the grass and tunneled the soil and molted the bushes. It shrank men’s hands into the hands of wrinkled apes; it rained a solid glassy rain, and it never stopped.

Roger Ebert on God

Take infinity. We know there must be an infinite number of numbers, because how could there be a Last Number? The more interesting puzzle is, how did there come to be a First Number, and why do many mammals other than man know how to count, at least a little? I don’t believe the universe counts. Counting is a mental exercise, and mathematics is useful to the degree it helps us describe and understand the universe, and work within it in useful ways. A Last Number is not important; only the impossibility of one.

Quantum theory is now discussing instantaneous connections between two entangled quantum objects such an electrons. This phenomenon has been observed in laboratory experiments and scientists believe they have proven it takes place. They’re not talking about faster than the speed of light. Speed has nothing to do with it. The entangled objects somehow communicate instantaneously at a distance. If that is true, distance has no meaning. Light years have no meaning. Space has no meaning.

In a sense, the entangled objects are not even communicating. They are the same thing. At the “quantum level,” and I don’t know what that means and cannot visualize it, everything that there is may be actually or theoretically linked. All is one. Sun, moon, stars, rain, you, me, everything. All one. If this is so, then Buddhism must have been a quantum theory all along.

Nixon’s undelivered moon disaster speech

Nixon’s speech writer prepared a speech for the event that Buzz Aldrin and Neil Armstrong wouldn’t be able to return to earth after landing on the Moon. The speech is rather positive despite the morbid circumstances it describes.

Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace.

These brave men, Neil Armstrong and Edwin Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice.

These two men are laying down their lives in mankind’s most noble goal: the search for truth and understanding.

They will be mourned by their families and friends; they will be mourned by their nation; they will be mourned by the people of the world; they will be mourned by a Mother Earth that dared send two of her sons into the unknown.

In their exploration, they stirred the people of the world to feel as one; in their sacrifice, they bind more tightly the brotherhood of man.

In ancient days, men looked at stars and saw their heroes in the constellations. In modern times, we do much the same, but our heroes are epic men of flesh and blood.

Others will follow, and surely find their way home. Man’s search will not be denied. But these men were the first, and they will remain the foremost in our hearts.

For every human being who looks up at the moon in the nights to come will know that there is some corner of another world that is forever mankind.

not everything is a poem

but these are two by Walt Whitman:

Are you the new person drawn toward me?
To begin with, take warning, I am surely far different from what you suppose;
Do you suppose you will find in me your ideal?
Do you think it so easy to have me become your lover?
Do you think the friendship of me would be unalloy’d satisfaction?
Do you think I am trusty and faithful?
Do you see no further than this façade, this smooth and tolerant manner of me?
Do you suppose yourself advancing on real ground toward a real heroic man?
Have you no thought, O dreamer, that it may be all maya, illusion?

Here are some excerpts from Whitman’s rather long “Song of Myself” (yes I am butchering it to extract my favourite parts, but it is 52 verses long; read the whole thing here if you’re interested):

I celebrate myself, and sing myself,
And what I assume you shall assume,
For every atom belonging to me as good belongs to you.

I loafe and invite my soul,
I lean and loafe at my ease observing a spear of summer grass.

My tongue, every atom of my blood, form’d from this soil, this air,
Born here of parents born here from parents the same, and their parents the same,
I, now thirty-seven years old in perfect health begin,
Hoping to cease not till death.

Have you reckon’d a thousand acres much? have you reckon’d the earth much?
Have you practis’d so long to learn to read?
Have you felt so proud to get at the meaning of poems?

Stop this day and night with me and you shall possess the origin of all poems,
You shall possess the good of the earth and sun, (there are millions of suns left,)
You shall no longer take things at second or third hand, nor look through the eyes of the dead, nor feed on the spectres in books,
You shall not look through my eyes either, nor take things from me,
You shall listen to all sides and filter them from your self.

Tenderly will I use you curling grass,
It may be you transpire from the breasts of young men,
It may be if I had known them I would have loved them,
It may be you are from old people, or from offspring taken soon out of their mothers’ laps,
And here you are the mothers’ laps.

This grass is very dark to be from the white heads of old mothers,
Darker than the colorless beards of old men,
Dark to come from under the faint red roofs of mouths.

I dote on myself, there is that lot of me and all so luscious,
Each moment and whatever happens thrills me with joy,
I cannot tell how my ankles bend, nor whence the cause of my faintest wish,
Nor the cause of the friendship I emit, nor the cause of the friendship I take again.

That I walk up my stoop, I pause to consider if it really be,
A morning-glory at my window satisfies me more than the metaphysics of books.

To behold the day-break!
The little light fades the immense and diaphanous shadows,
The air tastes good to my palate.

I believe a leaf of grass is no less than the journey-work of the stars,
And the pismire is equally perfect, and a grain of sand, and the egg of the wren,
And the tree-toad is a chef-d’œuvre for the highest,
And the running blackberry would adorn the parlors of heaven,
And the narrowest hinge in my hand puts to scorn all machinery,
And the cow crunching with depress’d head surpasses any statue,
And a mouse is miracle enough to stagger sextillions of infidels.

I find I incorporate gneiss, coal, long-threaded moss, fruits, grains, esculent roots,
And am stucco’d with quadrupeds and birds all over,
And have distanced what is behind me for good reasons,
But call any thing back again when I desire it.

These are really the thoughts of all men in all ages and lands, they are not original with me,
If they are not yours as much as mine they are nothing, or next to nothing,
If they are not the riddle and the untying of the riddle they are nothing,
If they are not just as close as they are distant they are nothing.

This is the grass that grows wherever the land is and the water is,
This the common air that bathes the globe.

My lovers suffocate me,
Crowding my lips, thick in the pores of my skin,
Jostling me through streets and public halls, coming naked to me at night,
Crying by day Ahoy! from the rocks of the river, swinging and chirping over my head,
Calling my name from flower-beds, vines, tangled underbrush,
Lighting on every moment of my life,
Bussing my body with soft balsamic busses,
Noiselessly passing handfuls out of their hearts and giving them to be mine.

And I say to mankind, Be not curious about God,
For I who am curious about each am not curious about God,
(No array of terms can say how much I am at peace about God and about death.)

I hear and behold God in every object, yet understand God not in the least,
Nor do I understand who there can be more wonderful than myself.

Why should I wish to see God better than this day?
I see something of God each hour of the twenty-four, and each moment then,
In the faces of men and women I see God, and in my own face in the glass,
I find letters from God dropt in the street, and every one is sign’d by God’s name,
And I leave them where they are, for I know that wheresoe’er I go,
Others will punctually come for ever and ever.

And as to you Corpse I think you are good manure, but that does not offend me,
I smell the white roses sweet-scented and growing,
I reach to the leafy lips, I reach to the polish’d breasts of melons.

And as to you Life I reckon you are the leavings of many deaths,
(No doubt I have died myself ten thousand times before.)

I hear you whispering there O stars of heaven,
O suns—O grass of graves—O perpetual transfers and promotions,
If you do not say any thing how can I say any thing?

I bequeath myself to the dirt to grow from the grass I love,
If you want me again look for me under your boot-soles.

You will hardly know who I am or what I mean,
But I shall be good health to you nevertheless,
And filter and fibre your blood.

Failing to fetch me at first keep encouraged,
Missing me one place search another,
I stop somewhere waiting for you.

Read the whole poem here.

Planet X and the “Wow!” signal

I wish that were the title of a film, but it’s merely a summation of my favourite stories from this NewScientist article: 13 things that do not make sense .

Also interesting was the question raised by homeopathy research (a field the concept of which I didn’t really understand before reading their summary here):

MADELEINE Ennis, a pharmacologist at Queen’s University, Belfast, was the scourge of homeopathy. She railed against its claims that a chemical remedy could be diluted to the point where a sample was unlikely to contain a single molecule of anything but water, and yet still have a healing effect. Until, that is, she set out to prove once and for all that homeopathy was bunkum.

In her most recent paper, Ennis describes how her team looked at the effects of ultra-dilute solutions of histamine on human white blood cells involved in inflammation. These “basophils” release histamine when the cells are under attack. Once released, the histamine stops them releasing any more. The study, replicated in four different labs, found that homeopathic solutions – so dilute that they probably didn’t contain a single histamine molecule – worked just like histamine. Ennis might not be happy with the homeopaths’ claims, but she admits that an effect cannot be ruled out.

So how could it happen? Homeopaths prepare their remedies by dissolving things like charcoal, deadly nightshade or spider venom in ethanol, and then diluting this “mother tincture” in water again and again. No matter what the level of dilution, homeopaths claim, the original remedy leaves some kind of imprint on the water molecules. Thus, however dilute the solution becomes, it is still imbued with the properties of the remedy.

You can understand why Ennis remains sceptical. And it remains true that no homeopathic remedy has ever been shown to work in a large randomised placebo-controlled clinical trial. But the Belfast study (Inflammation Research, vol 53, p 181) suggests that something is going on. “We are,” Ennis says in her paper, “unable to explain our findings and are reporting them to encourage others to investigate this phenomenon.” If the results turn out to be real, she says, the implications are profound: we may have to rewrite physics and chemistry.
