Re: Forum Migration

Thanks for all your hard work. +1 on this feature request: how do I get to the current comic page from the forum? - "xkcd" in the banner doesn't appear to be a link (IE11) The old forums had a useful clicky link thingy that went to the xkcd front page (with the current comic) if you clicke...

Are there any words which are their own definition? I thought of "self-explanatory" but that's kind of the opposite.

Sesquipedalian is pretty close to its own definition.

Re: Oscilloscope Stray Signals

Anyone know of a light-duty free compiler for Python? Python is interpreted rather than compiled (well, there is a compile step, but it's hidden from you). There are many free distributions. The simplest one is at http://www.python.org. Free distributions with more bells and whistles are available ...

Re: 1446: "Landing"

More interesting news from Philae - it bounced multiple times! The sensors detected 3 landings, at 15:33, 17:26 and 17:33 UTC. Notice that nearly two hours passed after the first bounce. Given the microgravity, how high a bounce would that be? Could it be instead a sensor malfunction, or a pad not ...

Re: What-If 0109: "Into the Blue"

not the earth, but the laser would recoil. which just means it wil smash into the earth at c (since it had infinite acceleration) and hilarity ensues. That's a fair point - I implicitly assumed the laser was securely bolted to the Earth and treated the whole laser+Earth system as a rigid body. In r...

Re: What-If 0109: "Into the Blue"

I'm no physicist, but wouldn't space's curvature mean that if you pointed it forward, eventually the laser beam would hit you in the back of the head? Assuming you stood there for the billions of years it took for that to happen. No. Curved space isn't the same as closed space. Think of a sheet of ...

Re: 1384: Krypton

Swing and a miss, Randall.

But I'd much rather read a comic that tries and occasionally fails than a comic that endlessly recycles punch lines about, say, cats that love lasagna.

Re: 1338: "Land Mammals"

What other Mammals do we keep as livestock and/or pets? Llamas, donkeys, buffalo, etc. Do zoo animals count? Would all the mammals in the world's zoos add up to enough to a square? I am guessing the top-center one is dogs. We keep more dogs than cats, right? I gotta think more people are dog people...

Re: Gravity and work done

There are various approaches to this idea in physics textbooks. One that I find helpful comes from the Matter and Interactions physics 1 sequence. The gist: think of the gravitational potential energy between the climber and the Earth as a property of the climber-Earth system. It has no meaning atta...
