Suffice it to say that my level of coffee-making care doesn’t really compete.

I’m an eclectic coffee drinker; I like espresso but also enjoy a really good cup of American coffee, and I prefer coffee black but am willing to adulterate it with milk if I suspect the quality is not going to be that high. (Sugar under no circumstances.) For the past few years I’ve relied on the lowest-effort method I know of that is guaranteed to produce a good cup: freshly-ground dark roast beans, placed in a simple cone filter and hot water poured right in. Practically instant coffee, but a result that can be as good as the beans allow.

But I’d like to start mixing more espresso into my home coffee experience, so I’m in the market for a new espresso machine. If I were a physicist of means, I might go for a work of art like the Elektra Micro Casa Lever on right. Or would I? This is a spring-action lever machine, which is to be contrasted with the manual levers, not to mention the automatics and super-automatics, and then there’s the matter of boilers, switches, heat exchangers … a complete mess. The pumps are certainly elegant, but I’d also like something that is functional and doesn’t require constant pampering. So I am in the unusual position of being frozen with indecision about what kind of espresso machine to get. Any opinions out there?

The ground rules here are:

1. There’s no such thing as right or wrong; different people have different tastes, for which different approaches are appropriate.
2. Answers with specific comparisons of advantages and disadvantages are more useful than simple insistence on truth.

I do understand that this is the internet and rules are unlikely to be followed, but I feel I should try.

Obviously not all advice on such a topic is too be trusted. The Engineer’s Guide to Drinks thread featured a sobering (as it were) number of people who think a “martini” should just be chilled gin rather than a proper cocktail, and were proud to admit it in public! So caveat lector. And if you want to talk about something other than coffee, be our guest.

That’s a slightly crazy Martini — 2:1 gin to vermouth. I think the pendulum has swung too far towards “dry,” but please.

Look at it! It’s fantastic! And when you cut it open:

Even better! And guess what? It’s deeeeeelicious. Slightly crispy like an asian pear, but reminiscent of a kiwi.

Where have you been all my life, dragon fruit?!?!? Certainly not in mainstream US grocery stores.

Many thanks to my hosts at the DARK Cosmology Center in Copenhagen for introducing me to this wonder food.

Doesn’t that word conjure up the majesty of space exploration? The triumph of human drive and ingenuity?

Or perhaps, it makes you think of an automated laser-guided milking machine?

Seriously. Wrap your mind around that. “Automated laser-guided milking machine”.

Cow walks in when it decides it’s ready to be milked. Sensors read a tag around the cow’s neck to determine if the cow is indeed ready to be milked. If so, the machine launches a veritable Pink Floyd Lasarium around the udder, locating the teats, which are then cleaned and hooked up to the milking units. Sensors then disconnect when the milk flow drops, and the cow goes on its way.

Lasers and cows. Two fine things that I never thought I’d see together.

For the many international CV readers, today is the US’s Independence Day celebration, which is in large part an excuse to bar-b-que meat products, blow up fireworks, and drink beer. If you’re tuning in from abroad, you are probable sober enough to read Daniel’s upcoming post on gravitational waves. For the rest of the drunken US crew, you can probably handle the Muppets.

PS. While we’re talking beer, I must recommend the current Full Sail Limited Edition L.T.D. (Recipe No. 3), sold in bottles with the pale blue label. Seriously. Try some.

I never thought the phrase “External Fuel Tank” could sound so, well, dirty.

Picture below the fold to protect the children. (From the always entertaining CakeWrecks).

“We’re going to split the bill,” said the organizer at my friend’s ninth grade birthday party. I didn’t think much of it until I ended up paying $40 for a $10 entrée. I felt cheated because I didn’t order a drink like most others. I was afraid to ruin the party mood, so I concealed my own anger, and that ended up ruining the night for me.

Now, I almost have sympathy; if you’ve ever gone to dinner with a collection of scientists, you’ll find that their vaunted mathematical skills tend to whither under the pressure of calculating tax and tip, and the person who volunteers to collect the money often ends up chipping in extra to cover the shortfall. But Mr. Talwalkar goes far, far overboard, devising an elaborate scheme by which everyone in the party receives emails ahead of time informing them that they will be strictly limited in the menu options once they reach the restaurant. It’s a common syndrome among people with something of a quantitative bent; fixating on the relationship between the money they are paying and the tangible goods in front of them in the form of food and drink, they completely discount the goods associated with having a good time in a social atmosphere and not worrying too much about who had how many bites out of which appetizer.

Admittedly, this guy probably gets more enjoyment out of solving a game theory problem and enforcing conformity with his rules than he would by relaxing and telling stories at dinner. That’s why you have to choose your dining companions carefully.

Our holiday season is filled with the joyful noise of loved ones asking “Would you like some bacon with that?”

One of the great things about being a physicist, it turns out, is the travel. I’ve had the opportunity to travel all over the world, including to some destinations that I might not otherwise have put on the must-see list. In fact I am at one right now, along with Robin and our five month old, Ian.

We’re in Taipei, Taiwan, at a joint UC Davis – Taiwan workshop somewhat grandly titled “From the LHC to the Universe”. The participants are just from UC Davis and Taiwan universities including National Taiwan University, Academia Sinica, and National Tsing Hua University. The workshop grew out of the fact that there are strong ties between the Davis faculty and that of NTU, especially in the area of particle theory. Our present dean, Winston Ko, a particle experimentalist, is from Taiwan, as is one of our recently retired but still very active particle theorists, Ling-Lie Chau. A number of the former postdocs and students of our theory group leader Jack Gunion are now at NTU, as is one of his close collaborators George Hou. And so the idea for this workshop was born, to further strengthen the ties between the particle phyiscs and cosmology groups at the two institutions, hopefully leading to more collaboration.

Perhaps the most striking thing I’ve found about Taiwan is the absolutely amazing friendliness, generosity, and hospitality of the people. Our NTU hosts have set the bar very high in terms of the organization of the meeting, our local accomodations, and events like the fantastic 10-course banquet we had last night atop Taipei 101, presently the tallest building in the world.

Wherever we travel, we love to eat, and the food here in Taiwan is superb. On Saturday we ate at the unpretentious but world-famous dumpling restaurant, Din Tai Fung. The service was amazing – for example, when I went to change little Ian’s diaper they set up a special changing station for me and stood there to assist me! For a battle-hardened parent of a five month old, this was incredible,
but it happened at the next restaurant at which we ate too!

Later in the day Saturday we ate on the street at the Shilin Night Market. It was a tough choice, and very inexpensive. We found a stall where you take a basket, and put into it lots of different food items on skewers, which they subsequently grill for you with a delicious garlicky sauce. Just grab a couple of what we call “walking around beers” and you are set.

Wherever we go, the sight of little Ian in the front pack inevitably brings smiles to people’s faces, who, with little hesitation, come straight over to coo at him and elicit smiles (and mostly he obliges). Clearly the sight of a western baby is a novelty here, and, of course, he’s pretty cute anyway.

Traveling with a five-month-old is a challenge: probably most of you reading this think we’re nuts to take him half way around the world…and you are probably right. But we’ve gotten along fairly well, hiring a baby sitter here who watches him in a back room of the physics department library. He’s gotten pretty fussy a lot of the time, partly due to jet lag, but he does that at home too!

Taiwan has a rich and turbulent history, right up to the present day. In fact, the day we arrived, the first non-Kuomintang president of the country, Chen Shui-bian (elected in 2000 and re-elected by a slim margin in 2004), was indicted for embezzling millions of dollars. A few days later, for the first time in decades, direct flights and shipments began between Taiwan and the mainland. The economic crisis is taking its toll on industry here, with people debating the relative merits of reducing pay or reducing hours (furloughs).

Our only regret is that we don’t have more time to see all there is to see on this beautiful island! We return home tomorrow, but hope to be back here some day.
