Photo: Dwingeloo Radio Observatory

Snapped on my first trip outside Amsterdam in the Netherlands, this is Dwingeloo Radio Observatory.  Constructed in the 1950s, it has a diameter of 25 meters which at the time made it the largest radio telescope in the world.  These days it’s no longer used for research and instead just by amateur radio enthusiasts, but it’s still located right by ASTRON, the headquarters for astronomy research in the Netherlands near the village of Dwingeloo.

Honestly I will be out at ASTRON so many times over the next few years I don’t feel obliged to give a full tour yet (already scheduled to go out twice next month, once for a full week!), but I thought it was a rather nice bit of scientific history to find hiding in a remote corner of Holland.

Dutch Culture Shock

Whenever you move to a new country it turns out many people are rather curious about the state of your culture shock.  Some have even asked me if I have much thanks to my travel/ Hungarian background, and the answer is of course a few things have popped up though I’m not going to be weirded out by, say, the existence of trams or that the plugs are different.  I mean I wanted to move here because it would be different!

That said, here are a few things that I’ve noticed are rather different in the Netherlands- and a few that actually I expected to be problems that really aren’t… Continue reading

Why I Love America


Wall Street, New York, New York

On the 235th anniversary of the founding of my country, I would like to say a few words about a few things big and small that I love about America.  I have been all around the world, but amazing as much of it is there is nothing like leaving your home to appreciate just what it is that makes it so wonderful.

As Seen in Astronomy Magazine

I just accomplished an old dream of mine: I went to my local bookstore, found the July 2011 Astronomy magazine on the rack, and purchased a copy that has an article written by me in it.  Just like that.

Ok, well not quite just like that- I sent the query article about a year ago, had to write and then do some changes on the thing, and then paid attention to other things until my parents wrote to me a few weeks ago saying a few issues of Astronomy and a rather nice check had arrived at their house (the issues were unfortunately waterlogged a little en route hence me buying new ones, but I would’ve wanted to go buy one myself anyway for novelty purposes).  But for someone who read the magazine religiously as a young teenager- seriously, they fell apart!- it’s honestly jarring to look at my own words there and how professional they look.  Strange thing to quip, it’s not like I want a hundred thousand people to read something that looked bad, but I suppose this is the advantage of editors who know better than you.

So if you have a moment over the next few days pop over to your own bookstore, library, or Nook and check out the Astronomy July 2011 issue.  My article is on page 50, “Visit Northern California’s Top Astronomy Sites.”  (Yep, an astronomy travel article- gotta write what you know!) I’m rather proud of it, though it makes me wonder which kid reading my words over and over will be the competition a decade from now…

Fall Preview: An American Astronomer in Amsterdam

This post is primarily supposed to be a statement that I will be moving to Amsterdam in September to start an Astronomy PhD, but because I can’t just make a statement when there’s a good story to be had I will instead begin in Beijing, China about two months ago. Continue reading

Tracking the Mountain Gorillas

About 4 million years ago, a monkey-like creature lived in the heart of Africa that would be known as the common ancestor of gorillas, chimpanzees, and humans. Having such a close common ancestor so recently in terms of evolution is like sharing a grandparent- humans and gorillas share over 98% of the same DNA, making us genetic cousins really. Estranged perhaps, but no one closer in terms of relatives. Continue reading

Masai Mara Safari


Posted from Jinja, Uganda- the source of the Nile!!!

The Masai Mara is essentially the Kenyan Serengeti- all that divides the two is an arbitrary line and a multi-hour journey via Nairobi unless you are some sort of non-human animal. Amazing stuff out there though, and here is a small fraction of what we saw-

Not one but two gigantic lion prides, and a lioness who was busy stalking her prey until the safari trucks cut in front of her (illegal but unfortunately common around here). I’ve never posted a picture of a male lion before though and this guy was so wonderfully lazy I can’t resist!

A hyena and a bunch of baboons and Maribu storks (closely related to their cousin in Europe who winter down here) checking out the food near a hotel’s compost heap. Not exactly natural, sure, but I love seeing multiple species together so here we are!

A cheetah panting in the midday sun as you surely would if YOU had to wear a winter coat in the middle of summer.  Such a beautiful creature, we were so lucky to get so close and share some time together (though he spent most of the time panting like a dog…).

The Masai Mara has th most giant hippo pools I have seen in my life.  You rarely see them out of the water in other parks because like us they can sunburn, but here it appears to be no issue.

This guy excited me because after this point new species are always exciting- a hyrax! This is doubly exciting actually because this rat-looking thing is actually the closest related relative to an elephant- I know, what?!- so they’re rather neat to see in order to contemplate the strangeness of evolution.  After all, whatever strange beast thought to give us the elephant gave us the hyrax, and what kind of world would we be in without that?

A bona-fide zebra crossing.  I really crack myself up sometimes.Last but not least, a whole mess of Masai giraffes.  We saw about 12 in this herd, two fighting each other and the rest just cruising through the underbrush with their heads sticking up like periscopes.  I’d never seen anything like it and that’s the great thing about safaris, you never run out of amazing things to see!

Safari-ing in Ngorongoro Crater


About 2 million years ago any of our ancestors who were in northern Tanzania were in for one hell of a fright when the then-tallest mountain in Africa- yes, taller than Killimanjaro- collapsed in on itself in a monstrous explosion that left behind a caldera with 100 meter walls all around and 100 square miles in the middle (yes, I’m mixing units, but it’s easier to remember this way). Today the bottom of the crater attracts animals from the nearby Serengeti and beyond and allegedly has the highest concentration of predators in Africa- in short, a safari well worth doing!

Photo: What Science Looks Like

I’m not sure if this is one of those things that only a mother could love, but my M.S. thesis (“An Extended Study on the Effects of Incorrect Coordinates on Surface Detector Timing”) is submitted and will be defended next week. This fellow, alias “Figure 6,” is the most colorful and hence cutest of the graphs.

Yes, I just called a bunch of Gaussian distributions cute.  Shut up!

For anyone who actually wants an explanation here, what I basically did for my M.S. thesis was take GPS units similar to those in the Pierre Auger Observatory and test to see what would happen if the position got increasingly wrong on them.  In addition to position data a GPS unit also gets timing from satellites, making them a very accurate clock, and accurate timing is exactly what you need when you’re trying to track a shower of particles hitting the ground at nearly the speed of light.  Literally every nanosecond counts!

Normally in the field we just set the position to make the timing data more accurate (because the GPS won’t have to worry about finding where it is and what time it is with each cosmic ray strike), but sometimes that’s off for a myriad of reasons.  So the above graph is the product of modeling that: one GPS “clock” was allowed to find the correct position/time and the other was given an increasingly incorrect position, and the difference between the two tells you what happens when you actually have an incorrect position in the field.  Then when you add up all those differences over the time it took to collect the data (five days was typical, with one data point each second) and plot the distribution, you discover that the higher you go the quicker you receive the signal.  Just what you’d expect when a GPS is getting signals from overhead satellites really: when you go higher up you’ll receive the signal just a little bit quicker.

And that, ladies and gents, is what science looks like.  Thank you, I’ll be here all week.

Journey into the High Andes

It’s impossible to be in the shadow of the tallest mountains of the Americas and not succumb to the urge to go explore them.  So on Thanksgiving Day I did just that, going on a day trip from Mendoza up toward the Chilean border. Continue reading
