They are emitted 180 degrees apart, and have nothing to do with alpha interactions from Americium. Completely different decay process.
This also has nothing to do with conservation of momentum, alpha decays cause the nucleus to recoil slightly, but since the atomic weight of the remaining nucleus is much larger than the alpha prticle, it doesn't move much. Photons have energy, hv, but by definition, no mass; i.e. no momentum.
These photons would go thru the ccd and would be very unlikely to show a blip.
But a chunk of cerium-doped sodium iodide would make nice flashes for the camera.
Obviously you had no idea what you were doing in high school, or have learned anything about it since, and you're giving HIM shit about not knowing advanced physics?
Make sure the trajectory can't be followed back to your house; and use a big enough, expanding round that he will question whether or not to even call the cops.
... like Chernobyl was the Graphite Reactor in Oak Ridge, (My hometown) and the production reactors at Hanford. These were build-as-fast-as-possible-to-save-the-world designs, built during wartime, and seriously contaminated the planet, even during relatively problem free operation. There is still an ongoing effort to remediate the Hanford site, and some areas are (radiologically)inaccessable to humans to this day. But the Graphite Reactor has Historic Register status.
But, nothing good comes without a price. The legacy of 'Nuclear' in general is inextricably linked to the atomic weapons that drove the development of reactor design. We didn't spend billions of 1940 era dollars to light our houses, we did it to blow the fuck out of whoever pisses us off enough. If it hadn't taken longer than it did, we would have used them in Europe, with everyones blessing, (at the time) because we didn't yet have an appreciation, or even definition of, 'fallout'.
We learned about reactor design, and built in safety systems to prevent most problems, and learned to put a shell around the core to contain most of the forseeable crap. I am unsure how a modern reactor shell would hold up to the series of errors involved in the Chernobly disaster, however. Three Mile Island vented some gases, but was relatively insignificant, even tho the core was laying in a lump of slag at the bottom.
The public, as a whole, only remembers the big events, even if the story is only partially true, from a certain viewpoint, and no other. In a war, the winner generally gets to write the history books. Politicians score points anyway they think they can; latch onto a popular cause, a newsworthy topic, or belief and make it their own. Wring it for all it's worth.
Nuclear power became a topic of protest for mostly political reasons; people seem to only see it from extreme viewpoints, and the older, entrenched politicians found it hard to counter the mushroom-cloud mentality that was the nuclear movement in the late seventies. At that time, there were tens of thousands more nukes pointed at us than there are today, so no one liked nuclear anything.
I've always read SF, and many potantial outcomes of human society have been written. Even with nuclear power, we will eventually use enough energy that we will have to cool our planet, or the seas will boil, just from our energy usage. This won't happen for a long time, but it happens before the sun goes out. Of course, some enterprising individual will make a fortune beaming the heat off as infrared, but I digress...
Chernobyl (remember Chernobyl?) was a really bad industrial accident. If we improve designs (google pebble bed reactor) and have better oversight of operations, we can use nuclear power to eliminate power problems for good. Excess capacity could make hydrogen, and if there enough excess power, we could form gasoline. (a bitch, but doable) We just need to get our shit together.
I've seen more than one 'news' story that was written with a slant that made no sense in the context of the other news I had read that day... the same regurgitated wire crap... but slanted differently than the standard polarized crap we call news.
I try to read enough different viewpoints to make sense of the original story, somewhere in the middle, rather than the right and left slants of the mainstream news outlets.
Occasionally, I'll see one that is directed in such a way to make me think, "Why bend it in THAT direction?".
... enough energy for your Entropy to equal infinity.
This does NOT make YOU God, however.
If the second coming ever happens, God is going to be so busy, with the troubles of his own flock, and of course, twits like you.
Me, I'm hoping there's enough of my corpse left for the Valkiries to carry me back to Valhalla, to spend Eternity drinking and whoring with Thor and that bunch; I'm sure Heaven would be fucking boring.
...to see that all those ICBMs that were aimed at us in the cold war were junk? They're cherry-picking the good ones to sell; I guess the bad ones would have blown up on the pad, instead.
...Seems to be the only country that gives a fuck about civillian casulties; me, I'd kill a shitload of 'em just to make people realize that I'm serious.
Boy, wouldn't that give the liberals shit fits...
The middle east would make a great spa for all the obese americans... after we killed all the towelheads, of course...
..Gllgle seems to actually mean 'dont be evil' when they say it.
The difference between 'business mogul' and psychopath is in the metaphor given by Zorg in Fifth Element: 'If I break a glass, these worker bots have something to do.'
Politicians always need their Eurasia to be the reason they're fucking you so hard.
High gas prices serve to piss off who, at what, exactly? Think harder. (not too hard. that way lies paranoia...)
(BTW...if the car companies own part of the oil companies, does that mean they'll make more fuel efficient cars?)
Megalomania fits the politician viewpoint much more accurately; the biggest difference in a megalomaniac and a psychopath is in scale and area of effect; a politician can fuck over large numbers of people; your average psychopath doesn't have control over millions of people. The real drag is that people like that are drawn to jobs like that.
What we as a society need, is a national draft of random americans to be government employees; that way, no one is there long enough to be corrupt. Use the same list as jury pools; that keeps the list clear of crackheads and the like, (not that crackheads are neccessairly bad people...) but at least the confusion will prevent the large corporations from owning ALL the legislation...
I completely agree here:
replace the op-amps, replace capacitors, and use thick-ass cable to the speakers.
mainstream manufacturers are using the cheapest components available that meet spec; good mylar,teflon,or polyester caps are measurably better than ceramic,in the audio realm; and I always use thick, rope-lay, fine-stranded speaker wire.
Just not silver speaker wire, or $10 capacitors.
The amp I finished last week was dc to 250Mhz bandwidth for buffering PMT's. 90dB SNR at 200MHz. The bitch was the jitter spec; less than 50pS fwhm. That took most of the time.
.. Of electronics I buy; the main amp in my car I bought for ~$150, put in ~$50 in better transistors, and a few critical resistors, and have a really nice amp, until it overheats. The watercooling project is next, I guess.
The thing in the article that pegged my bullshit detector is the 'audible difference' in capacitors. I design high frequency pulse amplifiers, and at subnanosecond risetimes, capacitors act pretty awful. but in the audio range, there is no way to hear the difference in a good quality capacitor. Below 1MHz there isn't enough difference to measure. You might hear the difference between a low quality, floor swwepings quality z5u capacitor at 20kHz, an a high quality silver mica cap, but I seriously doubt it.
P-channel mosfets are more expensive than N channel mosfets; If you look at the parts in any car amp, the P-channel parts are the lowest rated; replacing them is an easy way to improve the capabilities of an amp. but you have to upgrade the power supply as well, usually to take advantage of the improvement.
And replacing the resistors in the signal path with metal film, if they're not already, is an audible improvement.
Replacing the capacitors, with no design check, will result in shit blowing up, just as specified. Inrush current is a bitch. Replacing the output caps on a power supply board with larger ones is not a good idea; the lead inductance is a design constraint. The need to go in the same holes.
Also, FRED diodes are soft recovery, with no ringing. Schottky diodes ring like a bitch, and are why fred's were developed.
If you add capacitance to a switching power supply, do it at the circuit you want to help out, not at the power supply. The resistance of the wire going to the circuit board will damp the inrush current to the additional capacitance. 1 ohm of wire makes a huge difference in the surge current when you turn it on.
If I spent $10 on a capacitor, I guess I'd say I could hear it too...

Hope you also posted this on Groklaw...
Runs on everything, fits on my usb stick, Still fun after 10 (?) years...
My thoughts exactly...
Yeah, you are correct about the momentum thing; I forgot about Compton...Been awhile.
But, you still got the equation wrong:
A simple method to derive the expression for the momentum of a photon is given below.
from special relativity
DE = Dmc2
momentum = p = (E / c2)(v)
but v = c, therefore p = E / c
since E = hf = h (c / l),
p = (hc / l) / c
p = h / l
I still think you're a twit.
we were talking about Alpha decays.
They are emitted 180 degrees apart, and have nothing to do with alpha interactions from Americium. Completely different decay process.
This also has nothing to do with conservation of momentum, alpha decays cause the nucleus to recoil slightly, but since the atomic weight of the remaining nucleus is much larger than the alpha prticle, it doesn't move much. Photons have energy, hv, but by definition, no mass; i.e. no momentum.

When asshats like this win, we all lose
There is no text here. See? It says so...
Eventually, we will have to use energy to lose the C part of the CO2 back to a solid form.
Otherwise, we will eventually see major effects on the population, especially people with compromised breathing, the elderly, etc.
So, what we need now is a carbon nanotube weaver that runs on atmospheric CO2, and use THAT to build our space elevator with, as well as spacecraft.
Hell, carbon nanotube fiber, held together with crystalline carbon as epoxy. (that seems like a General Products hull, doesn't it?)
Now we just have to invent something like that BEFORE we all die horribly.
Anyone know how much co2 it takes to kill you?
So, just to inject some 'reason' into this flamefest,
What about Mars?
It's polar icecaps are melting at about the same rate as ours, and over roughly the same time period.
Are our Greenhouse gases spreading that far?
Or maybe, the Sun warmed slightly, warming both planets at the same time, over the same period?
Flame On!!
