Resistance is futile!

By the conservation of the momentum, the two created particles will separate each other by going away from each other so the total momentum is still zero.

Collide is the correct word for this. When two pool balls are colliding, what prevent them to penetrate each other is the electromagnetic force which maintain the integrity of each ball and they interact by this mean. A collision is an interaction when two things are close enough from each other.

Funny!

Fortran is a scientific programming language. You are an engineer, seems clear enough why you are not using Fortran. Any explanations needed?

The energy of a photon is characterized by its wavelength. In a laser, the wavelength is constant. You have a large amount of photons which are coherent but at an almost single wavelength. When the article is talking about 1 MeV, it falsely interprets this as if the laser is emitting a single photon at 1 MeV. That is not what happen. It emits many photons in coherence which the sum of energy of all the individual photons will reach 1 MeV or more. Each photon cannot create an electron-positron pair and all photons collectively cannot create an electron-positron pair.

A 1 MeV photon would be a gamma ray photon and it is not true at all, your laser doesn't change its wavelenght as more more "energy" is emitted. In fact, we should instead talk about the power of the laser rather than its energy. The power being the amount of energy emitted by unit of time.

However, if you take into account the probability for natural disasters in the SF area, you may end even with Detroit. This article is misleading because it considers the criminality as the only threat to decide to which extent a city is dangerous or not. That's not fair.

He could have leaked the plot to the USA in exchange of hospitality from the USA. ;-)

Well, did NSA actually knew or not about Heartbleed? Anyone can prove NSA was aware of the bug and did nothing to protect USA from a third party's threat?

Not completely true. Many want to be competent, however nobody wants to pay what this competency worth. You have to invest a lot of time to become competent and at the end, it must pay otherwise you are better to do something else. There is a lot of well paid jobs which don't require the efforts you need to put on something to become competent.

Well, businessmen are not actually a good measure of anything. So, quoting Watson doesn't mean anything and doesn't prove anything neither. You cannot extract a law from these quotes.

Cochlear implants are not restoring hearing as an hearing person believes it is. I have a friend with two deaf daughters and both of them are having cochlear implants since they are young and they cannot communicate normally even with cochlear implants. Many people believe the cochlear implants are correcting the audition like glasses are correcting vision. The correction glasses can be made to exactly compensate for the vision defect. The cochlear implants cannot be adjusted to compensate the hearing loss exactly.

Unfortunately, most comments on /. are just uninformed comments and an occasion for many people to just bash against deaf people. Really sad this subject has been published on /. I never thought people were so narrow minded here.

You don't know what you are talking about, really. You surely don't deserve 5 mod points.

I believe your description is grossly exagerated. In this world, deaf people are second class citizen, no doubt. This culture is just trying to counter balance the effect to be considered everyday of your life as a second zone citizen. It can be understood that some of them don't want to let go everything that was build around them to compensate for the handicap. This is a normal and perfectly understandable reaction. What I don't understand is why are you so angry against deaf people?

Most people without any hearing loss do not understand how deeply this handicap affect people in everyway in their life. Most of the time people are staring at them as if they are idiots because they didn't understand what was said and so on. As soon as you are shrinking the community, these people who are left behind are becoming completely isolated and left alone.

Deafness affect the relations you can have with others because it affects the communication unlike many other handicaps which do not affect communication but are restricting physical activities.

Sharing among deaf people is also an important part of pain relief.

I would like you to prove your point that deaf people are considering themselves as superior to hearing people. I have never seen that in my whole life and many of my relatives are deaf or hearing impaired. This kind of assertion needs some kind of serious backing. You are attacking a whole community without anything else to offer than your own mind. My experience proves me otherwise.

Survive for what? If we are stupid enough to wipe out ourselves from this planet, there is no point to try to survive elsewhere. That's for one. For two, survival in a such hostile environment means draining Earth ressoures for only a bunch of people. That's even more stupid than point one. Three, survival of the specie means sending more than two dozen of guys and gals on Mars. As soon as they will breed they will become genetically retarded and vulnerable to many diseases.

That survival thing is just a wet dream in the head of people without a clue about what is going on.
