    Why does dating seem so easy for other people but not me?

    There are some fairly obvious things to remember about dating. First, you won't meet many potential dates in your own home. Get out. Do something. If it's interesting and interesting people are doing it, so much the better. If there's an excuse to talk to people in there, even better. Find...

    COVID COVID-19 Coronavirus Containment Efforts

    Re: That video of Dr. Amy Acton. I really need to learn sign language. The person doing the signs seems to know things that nobody else in the vid is aware of.

    Physics Career path forward for a physics autodidact?

    Nuclear does have such need. Sadly, nuclear is not itself in much demand with the exception of a very few countries. The USA, for example, has not built a new reactor in quite some time. Canada, my country, last finished a power reactor in the early 1990s. We built a reactor for isotopes, but...

    Optimizing Round-Off Accuracy in Source Spectrum Calculations

    So the sequences was the following. Data was provided for a parameter in a standardized situation. This was a source spectrum for a total volume of material. We needed the source spectrum per cubic meter. There are 100,016 cubic meters in the total volume. Simple division. So then I come...

    Star Trek: Picard -- anyone seen it yet?

    Dirk Gently game pretty close. I only disliked about three things in the entire first season. https://www.imdb.com/title/tt4047038/ And hey! There's a second season. I didn't know that until just now.

    Star Trek: Picard -- anyone seen it yet?

    I have occasionally liked individual episodes of TV shows. I can't think of a series where I liked every episode. There were, for example, several episodes of Star Trek Next Gen that I could enjoy. Picard gets a "virtual reality" wife and children on a doomed alien planet, that was pretty...

    B Is "ten" independent of the chosen number base?

    In binary, 10 is 2 in base-10. In ternary, 10 is 3 in base-10. So the full statement would be. There are 10 types of people. Those who understand binary, and those who don't. [Pause for the pained groan "yeah, binary 10 is 2" response.] And those who didn't expect this to be a joke about...

    B Is "ten" independent of the chosen number base?

    There are 10 kinds of people in the world. Those who understand binary, and those who do not.

    Star Trek: Picard -- anyone seen it yet?

    Now I've watched the first five episodes. Still saying meh. Still doing most of the things I detested in the first three episodes. But compared to what I say about most TV series... At least I'm not throwing stuff at my TV and yelling.

    Dark Forest Theory: Uncovering the Scary Answer to the Fermi Paradoxon

    The only thing missing from the OP's explanation is that the alien civilizations are drastically more advanced than we are. And the cost of the weapons they use is small. So, if one civilization among a large number has the characteristic of killing off rivals when they can, and hiding when...

    MCNP keff > 1.0 depletion question

    An F1 tally is current integrated over a surface. It gives you particles counted per particle started. You normalize it by using the number of particles started. You also need to tell MCNP the area of the surface, unless it's a very simple surface which it can calculate itself. You use the SD...

    Starting a molten salt reactor

    You are correct. Pump heat amounts to approximately 1 percent of full reactor power.
