Comment No, and No (Score 1) 278

However if you used relativity it would always be right for any situation we have managed to encounter or create.

"No" # 1 - quantum world

"No" # 2 - black holes

There is no reason to assume that relativity is right everywhere. Saying it "would always be right" is unscientific, in the extreme.

though your Wikipedia reference doesn't really support your claim

Well, since you were the one to say that freight trains had priority over passenger trains, how about you support your claim.

but in much of Europe, the passenger trains do have right of way, even if they're running late

And in Canada (where I worked for CP Rail some decades back). It surprised me that the U.S. operated differently.

In the US, slow cargo trains have right-of-way, slowing down passenger trains.

Not quite. Passenger trains have priority, and only lose it when they run late and even then, it is not that freight has priority over passenger service but that it does not have to yield to passenger trains. It would be more accurate to say it becomes "first come, first served". Kind of like if you reserve a table, they hold it for you for a few minutes after the time you set, then it becomes available to all.

Comment Maintenance for all trains is high (Score 2) 195

Railways have the highest fixed costs of any transportation system. 25%, I was told 30 years ago when I worked on one.

High fixed, low variable cost. So adding one freight car = dirt cheap. Going one mph faster on a curve = very expensive, due to increased wear on rails, road bed, etc.

There is also the not small problem of grade. Trains dislike hills, with a grade over 1% being excessive to them. Cars routinely handle ten times this.

Grades dictate routes. The only way around this is tunnels & bridges. Either way, cost per mile for a track is much higher than for a road. With costs born by one company, rather than all of us.

It is a fundamental problem, that leads to the division of bulk (slow) hauling = railways, people & fast hauling = trucks/cars.

Submission + - The Search for a Fifth Force of Nature (bbc.com)

Jonathan Salinas writes: They're really beginning to consider killing SUSY because they are seeing that it has produced no concrete experimental evidence when it should have already. This sounds like quite the farce of force, but at least it's opening a path to the next step in uncovering the truth.

From the article: http://www.bbc.com/news/scienc...
"According to the simplest versions of the theory, supersymmetric particles should have been discovered at the LHC by now...Next year will be an important year for SUSY. The LHC will be smashing atoms together at almost twice the energy it did in its first run. Even those who are still strong advocates of SUSY, such as Cern's revered professor of theoretical physics, John Ellis, agree that if LHC scientists do not find super particles in the LHC's second run, it might be time for the hospital patient to be moved to the mortuary.

One of the alternative models being considered is the composite Higgs theory: "The composite Higgs theory also solves the fine tuning problem, albeit less elegantly and, just as with SUSY, there is no experimental evidence for it. It supposes that the Higgs is not a fundamental particle, but is instead made up of other fundamental particles bound together by a hitherto unseen fifth force of nature. This is similar to what is already known to happen with the strong nuclear force, which binds quarks together to produce nuclear particles like protons and neutrons."

Comment The biggest problem (Score -1, Troll) 188

The biggest problem is not that the Higgs field/boson/theory is wrong. Nor that BICEP2 is wrong.

The biggest problem is that physicists do not want a new theory. Everyone gets paid and paid well to keep doing the usual stuff -- CMB, inflation, Big Bang, String Theory, smashing particles together and looking for the oldest star.

Physicists prefer stuff known to be wrong over stuff that might be right.

Comment The worst kind of anecdote (Score 1) 377

Your's is the worst kind of anecdote -- non-typical usage.

You rented a car for a week so:
(1) you wanted to have fun driving around...in a battery-weighted car
(2) you were not going to be spending one to two hours a day in rush hour traffic...that a Prius was designed for
(3) because you were going to be doing more than typical amounts of highway driving...that a Prius is neutered by

Three strikes, your anecdote is out.
