Martian Clock

A Mars Clock with a novel elegant "Martian" hand movement. See it ticking your local Earth time at

[Martian Clock @Mars_Clock]

The best clocks to tell time on Mars. They work for Earth too, and use standard seconds only. At the stroke of the hour, all 3 hands point to that hour. See them at https://t.co/0xb5aFF90P . Desktop clocks can be downloaded from there (Java 7+ required). Paper published by AstTI.

@stuey_beef I don't think Labour would win an SV vote -- Conservatives and Restores would back the Reform candidate for an easy Reform win.

@lefineder During the Eemian interglacial. A lot of attention should be paid to the Eemian as a harbinger of where our current interglacial is going. Those people utilized fire, so check for fire-related technology and massive uncontrolled forest burnings in Europe and Asia.

@AucklandIsland Your ID is appropriate as I've always said climate change nuts should be sent off to the Auckland Islands, so they wouldn't frighten school kids anymore.

@SpringerMath The question is whether math has an independent existence, even though it has no matter or energy. Math reduces to ones and zeroes in its basic form, and constructive math uses that to make working computer algorithms. "I build, therefore I am" could be math's credo of existence.

@memcculloch Photons don't "move" at all, they just jump from emission to impact. They experience no time or spatial dimensions. Since we do, we map their manifold to ours and get some crazy things like the double slit problem, to which the answer is that the photon goes thru *neither* slit.

[Martian Clock @Mars_Clock]

@memcculloch Yes, "dark matter" in practice is just the difference between the Standard Theory and the observations. The same as "entropy" plays in thermodynamics. There is no need to model the difference as some kind of "matter", when it could have a dimensional cause, or anything unknown.

@DrPhiltill The speed of a brain is majorly size-dependent because neuron signals don't have far to go in tiny bug brains -- thus a fly sees us as slow dinos. If galaxies have brains (big if) they might fit your model, but hard to chat to them when they take 100K years to complete a thought.

@MendlovitzMark I was watching from New Zealand and around 10PM NZ time (=3AM Wisconsin time), the margin flipped from +4% Trump to 0.5% Biden, in a single flash. I told my wife "they are stealing it".

@brivael I would compare Elon Musk with Edison ("genius is 5% inspiration and 95% perspiration") and not with Einstein. However, if Elon Musk builds a Star-Trek-like warp drive, then he will be the new Einstein.

@elonmusk frightening road.

@esrtweet My background is similar to yours, retired now, but I reckon I hit Gödel's limit a few times when iteration hit self-referential loops. Pretty hard to give an example when it involves screeds of code. But recursion is the heart of Gödel's limit and it's not that uncommon.

@The_Anglo_Saxon Very well picked, the Auckland Islands are an underutilised resource.

[Martian Clock @Mars_Clock]

@WatcherGuru Andrew Jackson was right.

[Martian Clock @Mars_Clock]

@Andr3jH Right, but first you need to accelerate to that speed. That would take a long time -- accelerating at 1G for 1 year would bring you to the self-seen undilated speed of light (C) -- so to reach a self-seen speed of 2200xC would take a loooong time. I prefer warp speed, sigh.

@bumbadum14 I once received a zero on a math exam question (the exam had only 6 questions) even though I gave the correct answer. The professor had simply failed to follow my line of analysis. So I protested but to no avail, but I figured he'd give it back in the "roundabouts" -- and he did!

[Martian Clock @Mars_Clock]

@MattKingNorth @kaiviti_cam Wow, really wishing for that thumbs-down icon for this post.

@lefineder The "traditional date for the fall of the Western Roman Empire" is just that -- tradition. On the ground, the Empire with all its structures continued, but with a German emperor and mix of Roman-German population. To zero out their soldiery, as this chart does, is absurd.

@caffeineworship @JulietMosesNZ "Goldstein" is a common name, I've known one. Perhaps she does too and it was just a common slip. Can't be important.

[Martian Clock @Mars_Clock]

@rainey_iii @beffjezos @elonmusk Incorrect, because you "take" only a galaxy with "one civilization of us" as your sample. You don't accept a galaxy without "us" as a sample. That's called a "selection effect" and a "biased sample" and it totally invalidates your probabilistic argument.

@cruelsardaukar The Italian cities were abandoned when their aqueducts were destroyed. No water = no people. This isn't hard.
