Our modern concrete has not existed for "centuries"... Portland cement was invented about 150 years ago, and steel-reinforced concrete started being used just over 100 years ago.

A lot of concrete is used for making standardized "pre-molded" parts (blocks, panels, structural elements) and those can absolutely by made using a much slower process, stocked and then rapidly assembled during construction.

Here is an even more interesting question: if an ML algorithm can be considered conscious, do you even need to "run" it (whether on a computer or by a "group of people doing calculations by hand") for that consciousness

Keep in mind that surface gravity depends very much on density. The earth is pretty dense, having a core of mostly iron. Even a rocky planet can be a lot less dense if it's iron-poor, and so could have a reasonable surface gravity (b

Yes. At least in the case of American satellites. Basically all information produced by the US (federal) Government that is not classified is in the public domain.[1] There are all sorts of weaselly ways that companies and in some cases g

Why not? They "vanished" around the time that we "appeared", so there is no contradiction. Most recent evidence puts the earliest appearance of Homo Sapience between 300-500 Kya, perhaps even a bit more than 500 Kya. I

I'm really far from an expert on this, but I've read quite a lot on the subject and my understanding is that there is considerably more historical evidence for Gautama-the-Buddha being a single real person than for Jesus Christ, t

I'm not completely sure what it is you want to know, but basically there are two pieces to linux container tech (Docker and others). The first is a set of Linux kernel features that lets us isolate various aspects of processes in sep

This "expansion in perspective" leads me to an intersting speculation: If we could quantify the relative complexity of living organisms, we might find that the difference in complexity between the simplest ancient proto-bacteri

Take a look at the video "Inner life of a cell". It's a CGI visualization that shows the complexity of the molecular machinery in a cell. Even if you already have a good idea, this video is likely to expand your perspectiv

"Vested interest" doesn't have to be financial. They are not going to take away his Nobel price if it turns out that the expansion of the Universe is not accelerating, but nobody wants to spend the rest of their life saying &

Thanks for the heads-up. Although I'd like to evaluate the technical merits of this project independently of the political ideology of the people behind it, knowing this I won't be sending any money their way for "planets&qu

Oh yeah, toward the end of the article it does mention that... but those results by Adam Riess are unpublished , so it's just a spurious claim by a guy with a lot of vested interest for now.

Sorry, but the article you linked says nothing about "reversing the results" of the OP article, it is about the same research as the OP article... Which at best you might say reverses the results from the 90s which originally fou

Nice article, and this is certainly a topic that everyone should know a little about seeing how fundamental cement is to our civilization. But it left out something very important at the end there... steel reinforced concrete is fantastic

What you say has been "known since Aristotle" appears to be wrong. There is really no evidence that this ability, or any cognitive ability, is "unique to humans". Yes, humans have more of this ability to "recogniz

+1 for using jsonnet. An adequate language for this kind of task! (Here "adequate" is meant as high praise... too often the choice of config langauge isn't.)

As I understand it, with Purism, if you want to "pick it up in January" you'd better order it now! People have waited more than 3 months for theirs.

Actually, according to quantum physics, the world is functional. The Universe can be described by completely by a function (the universal wave function) and is completely time-reversible; you can run it forwards or backwards because it h

There seems to be some disagreement in the comments about relative salaries in Berlin and Canada. A tool I've been using to get a rough idea of salaries in different parts of the world is the GitLab compensation calculator: https:&#x

If this really was such an obscure but useful algorithm, someone should change the title of this post to help people find it in the future so it doesn't remain obscure (add "card drawing"?)

Pretty interesting. Probably right. So what's next? After flailing around for a while longer IBM will be up for sale. Who will be the buyer? That's easy: Microsoft!

This is a great story indeed, but I have to disagree with it in one respect. I do not think that Newton was the "last of the magicians" because I don't think you have to believe in a personal god in order to have the same se

It's a curious fact that although of course humans are mortal, and in theory corporations aren't, in practice there are only a very tiny percentage of corporations that have outlasted a typical human lifespan. In fact the average
