Imagine the following:
MD: "We will implant this device. It costs $20,000 but it will keep you alive for maybe another 20 years."
Patient: "How much if I take it without software?"
MD: "Huh, it comes with software, that's an essential part of it."
Patient: "Trust me, I'll get it from TBP. You can find anything there nowadays."
MD: "Sure... $19,500 it is then."
A few weeks later in a small article in a newspaper:
"Man found dead with USB cable plugged in abdomen. Was apparently trying to download software on pacemaker but ended up installing "Dance Dance Revolution". Neighbors reported loud tap dancing around 3 AM that morning."
And a few months later:
"Nominated for Darwin Award: When software piracy goes too far."
And another flaw in your comparison is comparing US coal figures with world wide wind figures. You thus exclude the highly lethal coal mines in such countries like Russia and China, which probably also have more flexible safety regulations in building and maintaining wind turbines. You also only counted direct death among miners, but fail to account for induced premature deaths by the various diseases that breathing dust for years inflicts (4000 cases of 'black lung' per year in the USA alone!).
I don't think people have to be told that working on a 100m+ pole in windy conditions is dangerous. Just as they know that mining is very dangerous. What they need to be told is the risks they get exposed to by coal.
Which would turn the great camera into a waste of money...
Do you really think the camera would still be great after they added such a back, with all the buttons, screen(s),...? Where would they put the battery? The room where the film used to go might suffice; but remember that a lot of electronics has to be fitted as well (add at least 5mm to the back of your camera). Never mind the control lines between the release and sensor. You are replacing a passive film with an active sensor that can't be "on" at all times, but needs to be activated just before an exposure starts and stop as soon the exposure end.
If it would be feasible to produce a back that fits the old film bay it would probably still be extremely expensive when compared to a DSLR. Remember, if this is more expensive than a DSLR no one, probably not even you, will buy it. Honestly, would you do a $1000+ investment (and that is a really optimistic price) on a camera that will not come close to the functionality and ergonomics of a modern camera?
Sorry to destroy your dream, but if you want a good digital camera stop revolving in nostalgia and buy a DSLR and get acquainted with it. You don't have to use all the bells and whistles on them. Otherwise, keep buying film to use with your great old one. Hey, maybe you could even do both...
The reasons that this might work for Hasselblad are: their system is modular, it is designed for this and their optics are so expensive that if you invested heavily into it, this back is probably cheaper than switching to the H system. And they have a very loyal following...
The 1783 eruption of the Laki fissure system was mostly basaltic in nature. Little ash was produced, mostly in phreatomagmatic explosions in the first few days. A similar eruption would be bad, but ash wouldn't be the biggest problem.
One of the biggest problems with this ash cloud was an anomalous wind situation and no rain over Europe. Would this eruption have occurred in normal conditions, flight restrictions wouldn't have affected Europe, except for maybe northern Scandinavia. This situation is unlikely to stay in place for 2 years.
The impact of this rather small eruption is so big because of rare conditions and a desire of authorities to err on the safe side induced by the great difficulties of detecting and estimating the effects of a thinning ash cloud. As reports turn out that a cargo plane here in Belgium got damaged on a short regional flight (Google translation), some might say authorities might not have been careful enough.
Even without reverting to scientific notation or a new SI-prefix they can go down to 0.001 yN before anyone starts to complain. That's 3 orders of magnitude beyond what they claim to be able to measure "soon" and 5 beyond what they did.
And besides that, popular press doesn't seem to have problems with reverting to "100 million billions of bytes or kilometers", so why not "millionths of yN". It's not as if anyone still has a feel for these numbers beyond "peta" or "femto"... except for the scientists that run into them.
Could be pretty soon then... You don't get free bags here (Belgium) anymore in super markets. You can get 1c bags made of corn, which are fully biodegradable. The process starts often before you get home... 10c will get you a proper reusable bag. Needless to say that you aren't inclined to throw those away. When this started I ended up forgetting my bags often, so now I have a stash of 20+ bags lying in my car...
You calculated the kinetic energy of a mass of water moving forward at 30kph. In a wave water is not moving forward at the wave speed, but rather gently in an elliptic trajectory. I gather you used 10m as amplitude and not crest to through height.
The energy flux of waves is given by the formula which you can find on this wikipedia page. A 20m (crest to through) wave with a period of 10s over a lenght of 50m gives you 20MW of wave energy. Still a lot, but almost 2 orders of magnitude less than 1GW.
Not quite right (check the date of the article before you cite it):
Colgan Air Flight 3407 with 50 fatalities (happened a month after the article was posted)
Also, those 80.000 deaths are (mostly) accidental, just as those 50 were accidental. The theater is about the non-accidental ones... It is not about preventing accidents but attacks. I still disagree with it, but if you start comparing accidental deaths to non-accidental you won't convince any policy makers. It is hard enough if you make sense...
But of course, the core of your post still stands. Air travel is very safe compared to other forms of transportation.
Indeed, as an astrophotographer I can say his images are high quality and I'm sure the comparison with Hubble is not his own. We know better than that... I use an even simpler setup (Losmandy GM-8, Canon 300mm f/2.8 Lens or 20cm Newtonian f/4.5 and modified Canon 20D camera) and even those images get compared to Hubble by people. That setup cost me less than 5k euros.
Hubble is about science, astrophotography as you get to see it is about "pretty pictures". We get as much sciene return as a casual wildlife photographer... By accident we may discover something (and we all dream of it...). Hubble press releases are "pretty pictures" as well; but usually distilled from valuable scientific data.
There are a lot of amateurs contributing to science, but you don't get too see much of them. Tom Boles for example has discovered over 120 supernova's (from Britain) and has been featured in the media (BBC). And he's picked a hot subject. Many others monitor asteroids, variable stars, faint comets and will never get noticed by a news channel...
His and astrophotographers' work is important though to popularize science. I myself got started by seeing images of the sky in books. Now I'm making them myself...
You are correct. The size estimate based on the assumption that it is a natural object is 90-190m, depending on the albedo. It is derived of the absolute magnitude (22.453). If it is a man made object, it is a lot smaller that that, probably smaller than 20m and in the size range of the 3rd stage of a Saturn V. A radar was scheduled to ping the object this morning and more information should follow soon...
An impact of a 100m object would be bad on a local scale, but not earth-crushing. Evacuating the affected area in 2 days would be near impossible if it were a densely populated area.
And I don't get why anyone would trust something as important as their money to a company.
If a Google data center burns down, there's a pretty good chance you won't even notice it. If your server burns, you will. Just like if a bank building burns down, you probably won't even notice it, but if your mattress does, you will.
If you don't trust Google to keep their noses out of your data, encrypt it.
But with a true HUD you wouldn't need to read a map. It would simply draw the next few hundreds of meters of your route on your windshield over what you see through your windshield. No more glancing at screens, just look where you are supposed to be going and see the traffic at the same time. Maybe it could add a bit of helpful information such as street names, but you have to avoid clutter, just as with any interface. But for more information; like a digital map, you would still have to look at a lcd-screen, preferably when traffic allows you to.
Maybe you should take a look at the entire land mass and start wailing. All major ice caps in the world are losing mass. Some places are gaining mass, but the sum is negative.
Possession laws in general are dubious to start with, but at least with, for example, drugs, people aren't trying to buy sugar and ending up with heroin, or having people just wander by and stick five kilos of cocaine under the seat of their car.
Oh, but that does happen. All to often drugs are hidden in goods, luggage or vehicles known to go to a certain location. Pray it doesn't happen to you, cause when you get caught in for example: Morocco, you are in hell. That one got out alive, although in very bad shape. If it happens in Singapore, you probably end up dancing on air.
In many last names with more than 2 words, the second isn't capitalized. For example Van den Berghe (from the mountain), Van den Heuvel (from the hill), Van den Eijnde. I haven't met any Flemish people with this kind of name which were all capitalized. Foreigners with these names (mostly Americans) seem to have capitalized all words.
This works well, until the teacher supplies clocks that have been tampered with to induce a 10% systematic error. You get to guess how many correct values of g turned up in that experiment... And who passed it.
Add: British Museum, Science Museum (London), Museo del Prado, Museo Nacional Centro de Arte Reina SofÃa (Madrid) and quite a lot of others (most Belgian museums I visited allow it as well) to the list that do allow photography. You're not allowed to use a flash or tripod at nearly any museum though, so bring a good lens and a sensitive camera.
The only museum that I visited in recent years that didn't allow photography was the Doge's Palace in Venice. It was allowed in the San Marco church though. I believe the prohibition of photography in a museum is only a cheap trick to sell more prints in the museum shop. But honestly, if the museum has to be scared of photographers taking better pictures without a tripod and decent light equipment, then their material sucks.
From the Wikipedia article you can get that the coupe Veyron does (and the convertible won't be far off):
0-100 km/h in 2.46s
100-200 km/h in 4.8s
200-300 km/h in 9.4s
300-400 km/h in 33s
I wouldn't say it drops off quickly after reaching 100. It does the 200-300km/h jump faster than my new car will do 0-100km/h... Keep in mind that the difference in kinetic energy between 300km/h and 200km/h is 5 times larger than between 100km/h and 0. It's performance is stunning and saying it becomes "slow" after 100 is like saying orbiting around the Earth in a Space Shuttle is dull after the launch. If you want to prove me wrong I'd accept a ride with a Veyron...
Oh, and that main straight on the VW Ehra-Lessien test track really is only 8.9km (or 5.5 miles for the metric disabled). You can measure this yourself with Google Earth or Google Maps.
I put my manual on my mp3 player as an audiobook, disguised as a Britney Spears track, amid 75 hours of contemporary brainnumbing popular music (mostly Britney Spears). I won't take out a plane, but it will be fun to see the brains turn to goo and leak out of TSA employees' ears (profided I hit those who have one)...

So are Relativity and Quantum Mechanics.
You say "theory" as if it's a bad thing, while it's the highest you can hope to achieve in science.
