What It's Like to Lead a Symphony Orchestra
Roberto Diaz: Leadership, of course, first and foremost, is about interrelationships with people. Certainly as a leader of an institution, being able to read people’s emotional needs or body language on any given situation is incredibly important.
As principle violist of the National Symphony in Washington or in the Philadelphia Orchestra, managing a section of twelve unbelievably talented and accomplished viola players and how this section related, not only to the rest of the stringed section but to the orchestra; and being, in a sense, the representative of the viola section in front of the music director, and when you add to that the fact that, on any given moment in a concert, the conductor may ask for something that’s a little bit different than what was rehearsed, how do you translate a gesture into leading a group musically in a certain direction?
So there are all sorts of unrehearsed, unstudied, unplanned decisions, and you do it with body language and you do it with emotional connection to the folks around you, and I think that all of those qualities that one has to develop and those skills that one has to develop come in extremely handy - with faculty, with board members, with staff, with students, with parents, with friends, with volunteers and the outside world, in representing the institution to the outside world.
Being able to read people’s emotions and people’s body language is something that, certainly, you have to develop these skills. There’s no question about it. Otherwise you miss tremendous opportunities and you probably have to spend a fair amount of time doing some repairs or damage control for things that could have been easily avoided.

Roberto Diaz, former first chair of the National Symphony Orchestra, explains how exactly you go about bringing 80 to 100 musicians together in one synchronized, improvisational team.
Why self-control makes your life better, and how to get more of it.

- Research demonstrates that people with higher levels of self-control are happier over both the short and long run.
- Higher levels of self-control are correlated with educational, occupational, and social success.
- It was found that the people with the greatest levels of self-control avoid temptation rather than resist it at every turn.
Ready your Schrödinger's Cat Jokes.
- For a time, quantum computing was more theory than fact.
- That's starting to change.
- New quantum computer designs look like they might be scalable.
Quantum computing has existed in theory since the 1980's. It's slowly making its way into fact, the latest of which can be seen in a paper published in Nature called, "Deterministic teleportation of a quantum gate between two logical qubits."
To ensure that we're all familiar with a few basic terms: in electronics, a 'logic gate' is something that takes in one or more than one binary inputs and produces a single binary output. To put it in reductive terms: if you produce information that goes into a chip in your computer as a '0,' the logic gate is what sends it out the other side as a '1.'
A quantum gate means that the '1' in question here can — roughly speaking — go back through the gate and become a '0' once again. But that's not quite the whole of it.
A qubit is a single unit of quantum information. To continue with our simple analogy: you don't have to think about computers producing a string of information that is either a zero or a one. A quantum computer can do both, simultaneously. But that can only happen if you build a functional quantum gate.
That's why the results of the study from the folks at The Yale Quantum Institute saying that they were able to create a quantum gate with a "process fidelity" of 79% is so striking. It could very well spell the beginning of the pathway towards realistic quantum computing.
The team went about doing this through using a superconducting microwave cavity to create a data qubit — that is, they used a device that operates a bit like a organ pipe or a music box but for microwave frequencies. They paired that data qubit with a transmon — that is, a superconducting qubit that isn't as sensitive to quantum noise as it otherwise could be, which is a good thing, because noise can destroy information stored in a quantum state. The two are then connected through a process called a 'quantum bus.'
That process translates into a quantum property being able to be sent from one location to the other without any interaction between the two through something called a teleported CNOT gate, which is the 'official' name for a quantum gate. Single qubits made the leap from one side of the gate to the other with a high degree of accuracy.
Above: encoded qubits and 'CNOT Truth table,' i.e., the read-out.
The team then entangled these bits of information as a way of further proving that they were literally transporting the qubit from one place to somewhere else. They then analyzed the space between the quantum points to determine that something that doesn't follow the classical definition of physics occurred.
They conclude by noting that "... the teleported gate … uses relatively modest elements, all of which are part of the standard toolbox for quantum computation in general. Therefore ... progress to improve any of the elements will directly increase gate performance."
In other words: they did something simple and did it well. And that the only forward here is up. And down. At the same time.
These modern-day hermits can sometimes spend decades without ever leaving their apartments.
- A hikikomori is a type of person in Japan who locks themselves away in their bedrooms, sometimes for years.
- This is a relatively new phenomenon in Japan, likely due to rigid social customs and high expectations for academic and business success.
- Many believe hikikomori to be a result of how Japan interprets and handles mental health issues.
