You can still opt out, just fill out a declaration that you don't have a TV. It can be done online in two minutes (it must be repeated every year tho). The difference is that before it was basically opt-in, with spotty enforcement, and

Wouldn't it be the smell of space suits and space stations, rather than space itself? I don't think astronauts have tried to breath the few particles in the vacuum.

Not true, but you still need a pretty big one. In order to resolve a 50cm object 238k miles away (average Moon distance) at visible light wavelengths you need a telescope with a diameter of 500 meters. In order to resolve some details on su

The ESO observatory in Paranal has its own electricity power plant, both natural gas and - recently - solar. Computers: multiple TB of data per day will be generated and will need to be archived, backed up, and made easily accessible. Every

The segments themselves are 100% modular and you could tile an US state with them. The main problem is engineering: the whole thing needs to behave like a single object, turning 360 degrees and moving between horizon and zenith (horizontal

More than temperature, the main problem is the atmosphere. Hubble can see a lot of infrared, and also ultraviolet, because it is in space. Ground-based IR telescopes are somewhat limited, and UV is non-existent.

Mostly size. Ordinary shooting stars are grain-of-sand sized, and what you see is actually the superheated air that they displace coming in at 10+ km/s. Something slightly bigger, like a rock a few cm wide, can cause a blinding firebal

Probably a satellite in low-earth orbit. They only take a few minutes to go from one horizon to the other. Since it is very bright, I am guessing it is the ISS. Update: Iceland is too far north (64°N) to see the ISS (max 51.6°N). Too bad.

Interesting. I am Italian and I had no idea. From the sound of it, these tourist-specialized trains will be a small niche. To be fair, trains are already heavily used for domestic tourism, in addition to personal or business travel. Most bi

Photons travel at the speed of light, and at that speed, any "subjective" time is zero. In Einstein's theory of special relativity, the faster you go, the slower your proper time appears to an external observer. At the speed

Short answer: no. Except maybe for picking up a word here and there. Reading Latin is somewhat easier, except for poetry, where the word order is completely hopeless. Source: I am Italian. Edit: most Italians study Latin in high school, but

Yes, any QWidget instance can be used directly in the layout. If then you want to reference it, the best option is to use the tuple syntax to assign it a name: (widget, 'name'). Check the slider example out (slider.py), it does ex

If you look in the tutorial, there is also a ___ (three underscores) magic widget for special layouts :) I can see the difference between one and three, but between two and three it becomes difficult :)

'result' and 'Enter numbers:' are exactly the same thing - two QT labels. The example code just changes the first one's text. If you run the code, you'll see it by yourself. PyQt is not really difficult, just b

No, you have to manually update widgets assigning them their new value (strings, and for labels also lists and dicts). I will think about such a feature but I have no experience with such dynamic frameworks :)

Quit is a built-in class, because is very common. There are also Yes, No, Ok and Cancel builtins. You could do the same writing ['Quit'] and binding it a function that quits the program. Binding is done using QT's signals&#x2
