Tim Keller on The Reason for God
Question: What inspired you to write “The Reason for God”?
Keller: The fundamental argument of “The Reason for God” is that it makes more sense of life to believe in God than not to believe in God. [There’s] a lot of things out there that we see, and if there is a God, I believe that makes more sense of the things we see than if you say there is no God. So, it’s actually an argument for what I believe. And it came out of the fact that I moved to New York City 20 years ago, I was surrounded by people who didn’t believe in God or Christianity and they said, “Why should I believe it?” and I just had a dialog with them and it’s really a book that simply summarizes all those conversations. The second book, “The Prodigal God” is the essence of the model of ministry we have at Redeemer which sees both moralism and you might say relativism as being antithetical to the gospel and that the Gospel of Jesus Christ is “I’m saved by sheer grace and therefore I want to live in a way that pleases God, but I’m doing it out of a sense of gratitude for God’s grace, not as a way of putting God in a position where he has to bless me.” So, we put it like this in “The Prodigal God.” Religion is, I obey therefore God accepts me, and the gospel is I’m accepted through what Jesus Christ has done on the cross, therefore I obey. So, in religion, I’m obeying out of fear that God is going to reject me and in order to feel good about myself, whereas in the gospel, I’m obeying out of gratitude and joy, not to get things from God, but just to get God delight in him and nearness to him and it brings a humility because it’s all an act of grace, it’s all a function of grace. And so, in “The Prodigal God,” we’re bringing that fundamental model to people as to what it means to be a Christian and why it makes us different in the city.

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.
