### Cuba Turns On Submarine Internet Cable

### Parent Questions Mandatory High School Chemistry

You are wrong on numerous levels. I'm guessing that you forgot that Pi is not a real number, it's an estimation.

Pi is a real number, but it isn't rational. Maybe that's what you were going for here.

You seem to have forgotten what a "Theorem" is as well and hell, you used the word!. Wtf? There are numerous types of "Math" that we simply can not prove true or untrue. We still use them, because to the best of our knowledge things work in a specific way.

You need to look up the meaning of a mathematical theorem: A statement that has been proven on the basis of previously established statements, such as other theorems, and previously accepted statements, such as axioms.

A theorem is a not the same as a scientific theory, even though the words sound similar. You might have intended to talk about axioms, which are a set of given restraints for a particular mathematical system.

Since the above is true, Math "is" science. Your second statement in bold is a fallacy so just plain old wrong. No wonder you posted anonymously.

There are two schools of thought of the question of "Is math a science?"

1. (1) The mathematical method follows a similar pattern to the scientific method, so it is science (or a least science-like).
2. (2) Math is the pursuit of interesting descriptions of possiblities. Mathematical 'theories' are interesting or uninteresting, not right or wrong.

I follow the second school and I think most other mathematicians do as well.

### Ask Slashdot: Best On-Site Backup Plan?

Give your mom a box of backups and ask her to hold on to it, it is "stuff you made" She'll never get rid of it. and if the house catches fire, it will be the first thing she grabs when she runs out.

### Are Data Centers Finally Ready For DC Power?

440VAC 3 phase is not common in the US. 480VAC is common in the US. 380VDC is a common intermediate voltage for switching power supplies. This means that a 380VDC input supply can be made using a relatively small mod to an existing supply.

### GPS Maker TomTom Submits Your Speed Data To Police

Real-time traffic information. Cool feature. It is not included in the GPS signal (just as you said), but is instead delivered using one of several other formats (FM radio, for instance).

You are correct. But I have used an 8-track cassette :)

### Kodachrome Takes Its Final Bow Today

Re:Bring back 8 track (262 comments)

This is a lot off-topic, but: 8-track studio recording was the hot thing in the late fifties when the Ampex 5285 and other multi-track studio records came out. Multi-track analog recorders remained very popular until digital multi-track started to replace the old analog units in the mid/late 1990's. Those studio 8-track machines do not have much in common with the continuous loop cassettes we also call 8 tracks. From a technology standpoint, Kodachrome has just as much reason to still be around as the 8-track cassette - none. From a nostalgia standpoint, maybe there's room for both.

### Students Banned From Bringing Pencils To School

How common is this? (426 comments)

I also have graphite under the skin on one finger from the same sort of accident. I wonder how comon it is.

### Google Patent Proposes \$2 Fee To Skip Commercials

Broadcast television is still free, over the air, and have always had commercials (in the case of PBS stations more subtle, but still there). I don't remember anyone promising me that cable would eliminate commercials. Provide better and more reliable picture quality and add choice, yes, but not change the actual programming delivered.

### UPS Setup For a Small/Mid-Size Company?

Re:Have you tested the UPS lately? (260 comments)

FM-200 is not Halon, it is the Dupont brand name for a non ozone depleting Halon replacement - heptafluoropropane. Still yet, the deployment works exactly as you describe.

### AT&T Sues Verizon Over "Map For That" Ads

I wish Sprint phones would roam at EVDO speeds on the VZW network like it did on the (former) Alltel network. Not gonna happen, but it would be nice.

### AT&T Sues Verizon Over "Map For That" Ads

This is not true. That red map is the VZW 3G (EVDO and not just 1xRTT) network just as they claim. They have basically upgraded their entire network to EVDO.

### People Prefer Angry-Faced Cars

When I read the post about letting the Beetle in, I just assumed they were talking about one of the old school "Herbie the Love Bug" Type I Beetles. Those are rare now and easy to wave in to a line of traffic. The New Beetle on the other hand is just another car in a sea of commuters to me.
