hope and happiness

tis the day to reflect on the past year.  

days are long, but years are short. 

i hope you all have learned some good lessons, shared some insights, had hearty moments of laughter, and pushed yourselves beyond what you think you are capable of.   and i hope that next year will be fulfilling.



i dont know why, but i've been motivated to do spring cleaning today.  my seasons are all messed up.

the courage of our questions

carl sagan remains a constant source of inspiration.  here he is teaching a class of young students about the cosmos.   it's interesting to remember back at how lessons and talks were given before the digital days of power point presentations. 

near the end of this video, carl says "there are in fact 100 billion galaxies, each of which contain something like a 100 billion stars....we find that we live on an insignificant planet, of a humdrum star, lost in a galaxy, tucked away in some forgotten corner of a universe, in which there are far more galaxies than people."  


"we make our world significant by the courage of our questions and the depth of our answers."

yes.

christmas sting

this is the first christmas day that my skin is stinging from a sunburn.   yesterday's trip to the beach was wonderfully warm and sunny - just wish i had applied a second round of sun block!

the world continues

hello everyone.   nice to write to you a few days after the solstice, a few days after the date some people feared the world would end.  i'd like to say "i told you so," but mostly i'm just happy that i wont be receiving ridiculous emails anymore (after having received them steadily for the last THREE years) or witnessing young students i talk to about science genuinely fearful because they heard some adults talking about this nonsense. 

my cynical side reminds me that it's just a matter of time before these easily-influenced people latch onto the next doomsday scare-for-all.   my optimistic side hopes those people will remember this non-event and believe in trusted sources of information instead of believing in silly rumours that dont make sense.   please trust me, the so-called planet niburu does not exist

anyway, here is a beautiful photograph of the mayan pyramid, el castillo, located at chichén itzá in the yucatán peninsula of mexico.  orion is there, peaking brightly behind the illuminated clouds.

yum!

a cloudy night observing

the consolation prize of a cloudy night at the observatory is usually a gorgeous sunset.

here is a very interesting short film (11 min).   the technique is interesting and the story is surprising.  nicely done!

AAO planning day

i'm up at siding spring observatory for a quick two-night data collection frenzy.   unfortunately, we're under a thick blanket of clouds, so not much data has actually been collected :(  instead, i'll show you some photos from the australian astronomical observatory's "planning day" that was held up here a couple weeks ago. 

the big 4m telescope lives in there.


several people from the astronomy side and from the engineering side of the operation gave short talks to highlight their work, science, and upgrades to all the facilities.  it was cool to sit on the dome floor next to the beast while listening to everyone speak.


a few instruments that manipulate the light collected by the telescope mirror live in a cage under the telescope at the cassegrain focus.


it was there that i found this note, in permanent market on metal: good luck :)


this black thing is the 2df instrument that usually sits way atop the prime focus cage at the end of the telescope when i'm observing.  (you can watch a beautiful video of 2df at work here)


there are many other telescopes at siding spring observatory.   this building is where the 2.3m telescope lives.  the entire building rotates around so that the opening on the top faces the same direction as the telescope points.  astronomers have to be careful though, because the bathroom is located outside the dome, and they can easily get disoriented if the dome spins while they are doing their business in the middle of the night!


this is the 2.3-meter telescope that lives within the square building.


and this is the ancient little computer that one uses to change filters for one of the instruments. 




for dinner at the AAO planning day, we traveled ~15 minutes north of coonabarabran to an aboslutely gorgeous winery.  





of course we set up some small telescopes, and enjoyed looking at the sun through solar filters.


unfortunately, thick clouds covered the night sky.  we enjoyed a wine tasting after the meal, and watched as a spectacular lightning storm performed all around us.

mote of dust

carl sagan is an author i often go back and reread.  his COSMOS series, written with ann druyan and steven soter, has made an impact on many people i know.   his "pale blue dot" monologue provides a chilling perspective on our special place in the universe.  





From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity — in all this vastness — there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we’ve ever known.

pythagorean visualization

remember learning that relation about a triangle with a right angle: A squared plus B squared equals C squared?  i think a lot of people can rattle that off off right behind E equals M c squared.  

the relation actually refers to the area inside the squares whose sides are the lengths of the edges of a right triangle. 

a little visualization goes a long way to understanding the popular phrase, eh?!

NASA johnson style

this gangnam style parody is equal parts embarrassing, entertaining, and awesome. it was made by the student's of NASA's johnson space center, as an educational outreach tool. 

also note that the woman and two men wearing blue body suits are actual astronauts:  Tracy Caldwell Dyson, Mike Massimino and Clay Anderson.   



the gift

during the build up of the holiday season, it doent get much sweeter than this :)

a long week

this nicely illustrates my week.

i'm happy for the weekend!

twinkle, twinkle: the new version

remember the new version of twinkle, twinkle little star that i wrote for science in the pub a couple months ago?

here's a video reminder





i'm showing it again, because several people have asked me to provide the lyrics.  so, here you go!




twinkle, twinkle little star
how i wonder what you are

opaque ball of hot, dense gas
million times our planet's mass
looking small because you're far
you really are a super star

fusing atoms in your core
hydrogen, helium, carbon and more
with such power you shine here
twinkling through our atmosphere

shining like a cosmic czar
i'm finding out just what you are

the largest stars glow hot and blue
supernova when they're through
or form a black hole or neutron star
outcomes that are quite bizarre

the smallest ones burn cool and slow
still too hot to visit though
most have planets zooming 'round
home to life we have not found

our sun's average as stars go
formed 5 billion years ago
half way through its life so far
twinkle on our mother star

twinkle, twinkle little star
now i know just what you are

saturn is cool

thanks to the bad astronomer, phil plait, i have just spent quite a bit of time enjoying entertaining videos by charlie mcdonnell.  charlie is a twenty-something british guy with a lot of hobbies, talents, and interest in science, which he likes to share through clever youtube videos he makes. 

here's a recent one about saturn, the floating planet with a death star moon :)

space whale

if you stare into the sky
on a clear winter night

when the starts are aligned
and the magic is right,

you may catch a glimpse
of the space whale's flight,

as he sings his song with
celestial might...

anti-stress for free

i wish this installation was located in my neighborhood!   italian artist, biancoshock, posted squares of bubble wrap - those little plastic pockets of air that create so much relief and enjoyment when popped.   he cut the bubble wrap into squares and listed the approximate time it would take to pop the full sheet.   so fun.   perfect for late trains!

cheetahs on the edge

what a beautiful animal the cheetah is.  this big cat is the fastest animal on land, running nearly 70 miles per hour in short bursts.

a recent study has investigated why bigger and bigger animals dont run faster and faster.     studying various types of lizards, the study found that lizards ran faster as they got bigger, but only to a certain point.   “Larger lizards’ legs can no longer support their body weight, and they have to change their style of running, making them slower," the study found.

the cheetah has achieved the right balance of weight, agility and strength, and it's amazing to watch.   just look how steady its head remains while running so fast...!
