They try it, the problem is that you can compare mass better than you can count molecules. So one of the approaches is, to manufacture a Si sphere as perfect as possible and calculate the mass from the radius and the properties of Si crysta

Is there a good discussion site for books like this? ( Since I will probably not read anything, let alone the entire book before it is vanished from the HN frontpage.)

There are two types of reports, fraudulent ones and real ones. The fraudulent ones will come from everywhere, while the real reports come only from pirate infested harbors. Therefore just subtract the mean report density and what remains sh

Well, first of all radiation is a entirely man made disaster, unlike a tsunami. And additionally I think that your wikipedia quote is a nice example, first no acute radiation syndrome fatalities is a nice statement, it is also true for th

The constraints of Fukushima and Chernobyl are vastly different. First of all, in Chernobyl the surrounding infrastructure was not destroyed. Second, they had an open reactor in Chernobyl, so it was immediately clear that they need to build

Looks interesting, just to take it for a quick spin I tested it with a small set of bookmarks. [1] Then I deactivated noScript and Disconnect and reactivated them individually. (Screenshots at http://imgur.com/a/fRrnp

Given how very SHOCKED!1! German politicians react, one could get the impression that they honestly believed the NSA would only spy on the lower classes.

Wait, shell code does not mean "here we inject machine code, that arbitrarily happens to spawn a shell" and instead means "here we launch a shell"? How did I miss that.

The analogy I was thinking of, is the situation where we find a alien computer, running a twisted raytracing doom. In which a Imp is hunted by hordes of humans with chainsaws. At some point we would probably have a bug compatible C version

Yes, it is a great answer. But someone did make this point, and deleted his comment. And I thought, that this is a interesting detail, which should not be lost for the discussion. Edit:Grammar.

Actually I am a Kantian idealist, who experienced QFT calculations. On the other hand, I have no first hand experience of a proton. So yes, I stand corrected. But empiricism dictates, that the experiment is correct and the theory is just a

The deleted answer was actually a great point, it was basically a nitpick on the first sentence of David Z's answer. A proton is really made of quantum fields. The problem with this statement is, that a observed object is said

Well, there is charge conservation as well as lepton number conservation. So at the vertex a (electron) neutrino can couple to a W+ and a e-, since the lepton number of the neutrino is 1 and the reaction products do not have a total charge.

If the neutrinos have enough energy, then they can just produce a lepton-anti-lepton pair. But for low energies the simplest process is creation of a virtual W pair, that annihilates to two photons. Trying to explain a bit, because of the

The size is not only determined by the underlying physics, but also by the environment. So there can be a arms race of size, the predator needs to be roughly the same size as its pray, so the larger pray has a evolutionary advantage which g

The OS on the air gapped system is not that important, since you don't have to deal with regular internet threats, and anybody who wants to attack you will use 0-days anyhow. But I think that the air gapped computer should have a diffe

I am actually not sure what a good explanation would be. The problem is to a large part, that the particle explanation for high energy physics offers no good analogy. ( You will often hear that a photon is exchanged between interacting part

Somehow I find this presentation reassuring. It mainly suggests to me, that the NSA/GHCQ has to do 'honest' traffic analysis, implying that they did not break any of the crypto primitives used in Tor.

This is a great demo. However I wonder, with one flywheel, they should only be able to rotate the individual robots along a single plane? ( And I am somewhat curious, what collective motion of more than one robot looks like. )
