Some months ago I posted about a possible breakthrough in the study of physics. Some physicists in Europe had collected data at the New Bern accelerator that indicated that certain subatomic particles called neutrinos had been measured to be travelling at speeds that were slightly faster than the speed of light. Of course if this were proved to be true it would put into serious controversy (once again) Einsteinís Theory of Special Relativity on the limits of cosmic speed that was theorized in 1905, proved mathematically and by experiment some years later, and generally accepted by the physics community over the past century.

Well in this morningís paper I read that follow-up tests indicated that a possible technical malfunction of timing instruments (sounds like a Boyer ignition failure) likely flawed the suspect measurements made last September. So is Einsteinís Theory still in tact? Only time will tell. Since the theory of relativity deals with phenomena that most of us mortals canít comprehend, we can still revel in the marvels of Newtonian physics that affect our Brit bikes on a daily basisÖ. Yes things like velocity, acceleration, inertia, friction, airflow are still safe.

See if we can get our resident physicist, Lannis, to weigh in on this one.

What say oh learned one?

If I ride my bike with the light of, it has a certain speed.
When I ride it with the lights on, the force of the light, sent forward must have a reaction force facing backward (one of Newtons laws).
Even so my bike does not slow down with the lights on.
Is that prove that Newton was wrong?

Good thing, because the brake light, facing backward, would have a reacting force forward, speeding up the bike...

crazy

If someone's going to come up with a completely new theory about how things work, it has to leave all the stuff we can actually SEE intact.

Back before Galileo, people who though that the sun moved around the earth had come up with incredibly complex theories to explain observed planetary motion ("epicycles"). Once we came up with gravity and "earth moves around the sun", suddenly it ALSO explained planetary motion and a lot of other things.

So for hundreds of years, Newtonian mechanics explained everything we could see and measure. Then (as we started to be able to see and measure things that were much more large and much more small), there were phenomena related to molecular motion, and the speed of light, that Newtonian physics couldn't explain. So Max Planck and Albert Einstein and a bunch of other smart guys, around the turn of the last century, came up with Quantum Mechanics and General and Special Relativity that DID explain the bending of light around gravitational fields, and explained particle tunnelling where a particle is Here and then it's THERE and it never was in between the two points (and we use those facts to build lasers and electronics these days).

But there's more to come - there's still things that Quantum Mechanics and Relativity don't explain, like how Gravity works and why the universe acts like there's way more mass around than we can see or measure. BUT - and this is a big But with prickly bosons and hot quasars on it - any theory that we come up with to enhance or replace what we have MUST also still explain the things we can see and measure.

And NOT (like cold fusion or faster-than-light thingies) just be amazing Popular Science results that get everyone excited and make a fortune for the guy who "discovered" it, before it's found to be bogus.

So - trust but verify, says I ...

OK, I admit it, I'm addicted to brake fluid.

But I can stop any time I want.

Does this mean that if I'm traveling faster than the speed of light and turn my headlight on I"ll be out driving it?

Mr Mike lad, who knows about that law that states, as soon as the time comes along for a good Bimble with your mates, it starts bloody raining mad

Friday I saw 18c and Clear Blue sky, today it's cold and raining, just perfick for the Pioneer on the morrow mad Then you see, Monday and back to the Hell Hole, it'll be 18c and bone dry. Don't it make ya sick mad


I'm from the SOUTH, the Deep South

well...

As long as nobody's violatin' the NATURAL law around here, then I'm not going to get all wound up about anything...

Personally speakin'.

I saw a Thai person in town the other day, in a skirt and high heels, that I believe was violating a LOT of "Natural Laws" ..... shocked

Here's the deal on pressure washers, chain saws, weed whackers, outboard motors ect. Find a place that will sell you "non ethanol" gas and use only that stuff. I fill up two 5 gallon cans a couple times a year. When I used ethanol laced gas I took apart every single carb on all my gas powered things every spring....sometimes twice a year. I never do it now. My pressure washer was purchased in 1988 and it still starts on the second pull every time. My Mongomery Wards roto- tiller started on the second pull this year. Both have the original spark plugs.

On the more complicated stuff I am in awe that Einstein was able to figure that time was indeed a variable and light speed constant(among other things) and explain it with simple examples. Proving it mathmatically and with real experiments took another 10-15 years. Galileo, Newton, Michelson and Morley, Planck and the rest of that crowd were certainly out in front of the curve.

When I took physics back in the sixties, "quantun mechanics" was an obscure chapter that we skipped over.
