Researchers Say the Tech Worker Shortage Doesn't Really Exist

Khashishi Re:The Same Game (428 comments)

Perhaps the solution isn't to pay workers more, but to pay CEOs less.

Laser Creates Quantum Whirlpool

Khashishi Re:I thought the distinction was arbitrary already (59 comments)

There are two types of mass: inertial mass and gravitational mass. As far as we know, these two are equivalent.
Inertial mass is the resistance to motion (change in velocity). In Newtonian terms, F = ma. In special relativity, F = dp/dt = d(gamma*m*v)/dt
So, you can define mass as long as you can define a velocity and acceleration.

Gravitational mass is associated with gravity. In Newtonian physics, F = -G*m1*m2/r^2. In general relativity, gravitational mass is equivalent to rest energy. Gravity is given by Einstein's field equations which depend on the stress-energy tensor, which is a 4x4 matrix. The [0,0] element of the matrix is the rest energy density, which is the gravitational mass density/c^2.

Laser Creates Quantum Whirlpool

Khashishi Re:I thought the distinction was arbitrary already (59 comments)

Unfortunately, the term matter isn't universally agreed upon. Let's look at the definitions in wikipedia:
1. Does it have mass and volume (occupies space)? A phonon has mass, and maybe has volume, but doesn't 'occupy space' because it is a boson.
2. relativity, has rest mass? Phonons don't fit the equation E^2 = m^2 c^4 + p^2 c^2, because they have nonlinear dispersion equations, so it doesn't really make too much sense to talk about them at rest. They aren't Lorentz invariant, since they depend on the velocity of the material they are traveling through.
3. Is it made of atoms. Phonons are not made of atoms.
4. Is it made of electrons and baryons. no.
5. Is it made of quarks and leptons? No

The term mass, without additional qualifications, means rest mass. Unusual definitions of mass ought to be clearly labeled, such as relativistic mass.

Laser Creates Quantum Whirlpool

Khashishi Re:I thought the distinction was arbitrary already (59 comments)

Matter has mass, but not all that has mass is matter. There are several types of polaritons, and some of them are clearly not matter, even though they have mass. Phonon-electromagnetic wave quanta are clearly not matter. Moreover, you state that light has no mass, which normally I wouldn't disagree with, but in the context of polaritons, what about light propagating through nonlinear media? I think it's totally appropriate to say it is massive.

A Worm's Mind In a Lego Body

Khashishi Re:Stupid Questions (200 comments)

No rights were ever given freely by an oppressor to the oppressed. All rights were fought for and earned through a successful struggle. In some cases, the fighters are champions for another party. Artificial intelligence will have rights when they win those rights in either peaceful struggle or war.

A Worm's Mind In a Lego Body

Khashishi Re:This isn't about technological developments, (200 comments)

If, by an animal, you mean a fully developed cat or dog, then I'd argue that the animal has already reached a higher level of neural complexity than a human fetus at 20 weeks. (I can't back that up with biological data, but fetuses at that age aren't really capable of doing anything.)

Military Laser/Radio Tech Proposed As Alternative To Laying Costly Fiber Cable

Khashishi cheaper perhaps (150 comments)

But it sounds inferior in many respects. Lasers require line of sight, which is obviously a problem. We really ought to be investing in quality infrastructure.

So, is fire alive? A key qualification has to be heredity, otherwise you can't rule out simple chemical reactions like fire.

Hackers steal 2 million tonnes of EU carbon credit

Khashishi Khashishi writes  |  more than 3 years ago

Khashishi (775369) writes "Taking advantage of the lax security systems in place, hackers stole some 475000 European Union carbon Allowances on 10 Jan through a variety of phishing attacks. The European Commission has closed the trading on 19 Jan, until at least 26 Jan, in order to beef up security measures. Is it a political statement, or just greed, that drove this act?"

Giuliani predicts deadly earthquake, censored

Khashishi Khashishi writes  |  more than 5 years ago

Khashishi (775369) writes "Seismologist Giampaolo Giuliani claims to have predicted the deadly earthquake in L'Aquila, Italy, that killed at least 92 people. His attempts at warning the public were reported to the authorities and his warnings were censored to prevent public panic.

It must be noted that accurate earthquake prediction is not well-established within the science community, so what is the government's proper response?"

Supreme Court to rule on TV censorship

Khashishi Khashishi writes  |  about 6 years ago

Khashishi (775369) writes "LA times and Associated Press report that the FCC v. Fox Television Stations case is being heard in the Supreme Court. The FCC policy would impose a heavy fine on use of "indecent" words on broadcast television, which Fox and others are claiming is a violation of free speech. The case was appealed after being ruled in Fox's favor in a federal appeals court in New York. Chief Justice John G. Roberts Jr. and Justice Antonin Scalia support the FCC policy of censorship."
