Curiosity

Constellations

Had a bit of a wobbly today. How unlike me, Mr. keep all your emotions in check – Mr. Vulcan – Mr. emotions are illogical and apply all your will power to keep the oceanic currents that surge through your mind under control. And a wobbly from a completely unexpected direction too.

I’ve been excited about the Mars Curiosity landing for years, more so in current months as the noise leading up to today’s landing has intensified. I’ve followed most of the commentary about the complexity and engineering magic required to put an SUV sized scientific laboratory on Mars. About the 7 minute dance from orbit where nobody will know if the lander made it. I’ve listened to the discussions about the most sophisticated parachute in the known universe, about the impossible manoeuvres of the sky-crane as it deploys the lander and then flies off, blind, to crash as far from the landing site as possible. The incredible set of mechanical dependancies, a thousand unbroken links required to see the mission through to a successful outcome.

Now we are on the brink of this mighty endeavour. Men and woman are congregating from around the world to bear witness of this triumph of the very best the human spirit and our quest for exploration has to offer. In celebration I’ve booked out half an hour in my diary to watch the live stream, to see history at its finest in the making.

With joy in my heart I donned my constellation cufflinks this morning and headed off to work where … nobody knew about Curiosity but worse, so much worse … nobody seemed to care. I am surrounded on all sides by people who can tell me, in excruciating detail, what happened in any number of horrific reality TV shows. I tried explaining the landing to a few people and got a slightly incredulous “why is this strange person telling me this” look. I looked around me and suddenly wondered how it come to this. How did I manage to squander a lifetime’s love of science for this. Where did that thirteen year old boy go who used to voraciously read his way through the astronomy and science section of the public library? The teenager who was accepted into quite a prestigious astrophysics program and then listened to his teachers and family to do something else because nobody would be able to sustain a family on what a scientist made? My engineering grandfather thought engineering would be a good profession, as did my aptitude tests, and so I muddled through a year of chemical engineering before realising that – although I loved the maths and the science, I couldn’t work for the rest of my life watching fluids flow through pipes or in the bowels of some big smelly refinery. Medicine. That was a noble profession, who didnt like helping people they said – and it would be intellectually stimulating; You could make a real go of that with your academic honours and the doors to any university wide open. And so I did … until 4 years in I realised I wouldn’t be able to externalise the sickness and the suffering; I wouldn’t be able to walk away at the end of the day and go home to my family with a clear mind. I finished my degree, my poor long suffering father would have wept had I changed careers again, and while I was ticking that particular life box I started a computer company to make money … because I was sick of waitering jobs I was good at computers and programming.

One thing led to another, I met a girl, she got pregnant, we had a beautiful son, got married, and suddenly we had bills and medical aid to pay for. I stuck with computers because I could help pay those bills and buy formula and nappies and toys and the odd cheap self-catering family holiday. Now I’m twenty years out of school, have two beautiful boys, am still stuck in computers because they pay the bills and the rent and the school fees and the medical aid. in my spare time I escape into my head and create worlds there. Science fiction is my poison and my passion; I love writing and I know enough hard science to get a pass from the critics – and somehow, inspiring my readers feels like I’m repaying what I’ve squandered in poor life choices.

But today was hard. Today I’m both celebrating life and the human spirit and privately chocking back the tears because it is such an amazingly important day, and nobody cared, and I’m trying to figure out how I got from there to here.

Arthur C. Clarke Died today

Today is a very sad day indeed; Arthur C. Clarke died at the age of 90. Author of books like 2001: A Space Odyssey, Childhood’s End and Rendezvous with Rama – Clarke was one of the most influential authors from my early childhood onwards.

Some of my favourite quotes:

  • “Any sufficiently advanced technology is indistinguishable from magic.”
  • “If we have learned one thing from the history of invention and discovery, it is that, in the long run – and often in the short one – the most daring prophecies seem laughably conservative.”
  • “Somewhere in me is a curiosity sensor. I want to know what’s over the next hill. You know, people can live longer without food than without information. Without information, you’d go crazy”

And in his famous 10 word story:

“God said, ‘Cancel Program GENESIS.’ The universe ceased to exist.”

His vision and optimism about the continuance of our species will be sorely missed.

The Universe Is 13.73 Billion Years Old

CaptainCarrot writes “Phil Plait, aka The Bad Astronomer has summarized for his readers the new results released by NASA from the Wilkinson Microwave Anisotropy Probe (WMAP), which has been surveying the 3K microwave radiation left over from the Big Bang. Some of the most interesting results: The age of the universe is now known to unprecedented accuracy: 13.73 billion years old, +/- 120 million. Spacetime is flat to within a 2% error margin. And ordinary matter and energy account for only 4.62% of the universe’s total. Plait’s comment on the age result: ‘Some people might say it doesn’t look a day over 6000 years. They’re wrong.‘”

Researchers discover gene that blocks HIV

A team of researchers at the University of Alberta has discovered a gene that is able to block HIV, and in turn prevent the onset of AIDS.Stephen Barr, a molecular virologist in the Department of Medical Microbiology and Immunology, says his team has identified a gene called TRIM22 that can block HIV infection in a cell culture by preventing the assembly of the virus.”When we put this gene in cells, it prevents the assembly of the HIV virus,” said Barr, a postdoctoral fellow. “This means the virus cannot get out of the cells to infect other cells, thereby blocking the spread of the virus.”

Microsoft WorldWide Telescope in Action

Witness the power of the fully operational Microsoft WorldWide Telescope, as Roy Gould and Curtis Wong walks the audience at TED through this stunning software effort. Some experts say that the WorldWide Telescope, which puts together terabytes of information from telescopes all over the world to make a seamless rendition of the entire known Universe, will change the way we—the normal humans—understand the cosmos. After seeing it in action, I agree:

Microsoft’s Worldwide Telescope

Several days ago we wrote about something extraordinary that Robert Scoble said was coming from Microsoft and it was going to be announced on February 27th. When he saw a live demo of it at a recent visit to Redmond, he said it was enough to make his eyes well up with tears. TechCrunch is now speculating that this extraordinary something from Microsoft is a WorldWide Telescope. The desktop software would be available for Windows users and would allow them, as Michael Arrington says, to “pan around the nighttime sky and zoom as far in to any one area as the data will allow.  Microsoft is said to be tapping the Hubble Telescope as well as ten or so earthbound telescopes around the world for data. When you find an area you like, you can switch to a number of different views such as infrared and non-visible light.”

This would be wonderful for people who are interested in astronomy but don’t necessarily have the time or the access to the real thing.  I will be very interested to see how this stacks up against Google Sky or other desktop software like Stellerium.

U of MI Produces Strongest Laser Ever

I wonder if you can attach these to sharks?

eldavojohn writes “Weighing in at a mere 20 billion trillion watts per square centimeter and containing a measly 300 terawatts of power, the University of Michigan has broken a record with a 1.3-micron speck wide laser. It’s about two orders of magnitude higher than any other laser in the world and can perform for 30 femtoseconds once every ten seconds — some of the researchers speculate it is the most powerful laser in the universe. ‘If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam made in a University of Michigan laboratory … To achieve this beam, the research team added another amplifier to the HERCULES laser system, which previously operated at 50 terawatts. HERCULES is a titanium-sapphire laser that takes up several rooms at U-M’s Center for Ultrafast Optical Science. Light fed into it bounces like a pinball off a series of mirrors and other optical elements. It gets stretched, energized, squeezed and focused along the way.’” And … cue the evil chortling.

I guess this goes towards the comments on my last posting.  It isn’t easy to build a big fence around a marine environment and protect the bits on the inside.  Marine environments are complex inter-dependant ecosystems; anyone who’s owned a marine tank will testify to how hard it is to keep everything running happily.
