Jets’ DB Revis Said Best Ever

first_imgFLORHAM PARK, N.J. — Brandon Marshall has seen enough of Darrelle Revis to declare him the best cornerback in NFL history.Yep, that’s right. Move over Deion Sanders. You, too, Mike Haynes. Champ Bailey and Rod Woodson? Nope. Marshall thinks his New York Jets teammate tops them all.“I have been around great ones, practiced against Champ Bailey, Peanut Tillman,” Marshall said on ESPN’s First Take. “Played against some great guys. I didn’t play against Deion, but Revis is the best in the league.”Then came the headline-making — and eyebrow-raising — money part of the quote: “Ever.”Marshall reiterated his comments after training camp practice later in the day, praising Revis’ approach on the field — in games and at practice.“Now, I never got a chance to go against Champ in his prime. I’ve always practiced against him,” said Marshall, who was teammates with Bailey in Denver from 2006-09. “Darrelle’s really good at what he does. He’s excellent at what he does. He’s a technician. He’s really crafty, and he’s really smart. He works hard.”It’s a bold statement by Marshall, who’s entering his first season with the Jets but has faced Revis several times. One of the early highlights of training camp this summer has been watching Revis and Marshall go up against each other in 1-on-1 drills.“It’s a great compliment from Brandon,” Revis said. “Played against him through our whole careers and we’ve had some battles. He’s won some battles when we played against each other in the past and I’ve won some. I think it’s just a mutual respect that we have for each other. Now we’re teammates, and I never thought we’d be teammates in my wildest dreams.“Now we get to compete against each other and I’m glad he’s on my team because I don’t have to look across the huddle and see that it’s Brandon Marshall.”Revis certainly has the credentials to be in the conversation. He’s a six-time Pro Bowl selection and a four-time All-Pro pick, and his catchy nickname — “Revis Island” — is a tribute to the way he shuts down opposing wide receivers, stranding them downfield and out of the play.“It’s an honor,” Revis said of Marshall’s comments. “I mean, I don’t really have that many words for it. I know it’s an honor and I appreciate it. People see your body of work and what you’ve done, and I’ve still got a lot of ways to go.”Seattle’s Richard Sherman, Arizona’s Patrick Peterson and Cleveland’s Joe Haden are all often mentioned along with Revis as the top cornerbacks today.Jets coach Todd Bowles was an NFL safety for eight years, and has been coaching in the league since 2000, so he has seen a lot of great players come and go — some all the way to the Pro Football Hall of Fame.“When I was growing up, Mike Haynes was one of the best I’ve ever seen,” Bowles said. “But you can argue Deion, Revis, you can argue Sherman, Peterson. It all depends on who you’re playing with and who you’re going against. It’s all relative.”But, in Bowles’ mind, Sanders still holds the title of “best cornerback ever.” At least, for now.“You’ve got to go through a career and then get put in the Hall of Fame and measure it that way,” Bowles said. “The things that Deion was able to do as a player — punt returning, kick returning, offense and the speed he had, the awareness he had — that’s hard to be matched, in any era. Mike Haynes was before that, and I thought Mike was the best that ever played and he doesn’t get talked about.“It’s a good barbershop argument.”Revis, feeling the love from Marshall, offered high praise to the playmaking wide receiver who has 773 catches for 9,771 yards and 65 touchdowns in nine seasons.“If there can be another Megatron, it would be him,” Revis said, referring to Detroit’s Calvin Johnson. “I would put those two, (Marshall) and Calvin Johnson, in the same category of big, tall receivers, 6-5, 230-plus, and can run like a (smaller) skill player.”Oh, and when asked what he thought of Marshall’s statement that Revis is the best ever, fellow cornerback Antonio Cromartie didn’t hesitate.“True statement,” he said. Even better than Sanders? “True statement,” Cromartie repeated with a big smile.(DENNIS WASZAK Jr., AP Sports Writer)TweetPinShare0 Shareslast_img read more

Gyroscopes unexplained acceleration may be due to modified inertia

first_img Explore further Experimental evidence adds to the likelihood of the existence of supersolids, an exotic phase of matter According to the model, in order to conserve momentum, the gyroscope attempts to move with the ring by accelerating in the same direction. For clockwise rotations, the gyroscope should accelerate at a rate of about 2.67 x 10-8 times the acceleration of the ring. For counterclockwise rotations, the gyroscope should accelerate only about half that much.This model’s predictions closely match Tajmar’s observations, in which the gyroscope’s acceleration was about 3 x 10-8 times that of the ring for clockwise rotations, and half that for counterclockwise ones. MiHsC does not have any adjustable parameters, so it agrees with the observations without being numerically tuned.McCulloch’s model can also explain why the counterclockwise acceleration is smaller than the clockwise one. As the gyroscope starts to spin with the ring, it changes movement relative to the fixed stars. When in the northern hemisphere (where the experiment was performed), this effect causes a greater acceleration when rotating clockwise. But the model predicts that, when performing the experiment in the southern hemisphere, the gyroscope should accelerate more when rotating counterclockwise than clockwise, while still following the ring’s rotation.“Inertial mass has not been well understood and has been assumed to be the same as gravitational mass (the Equivalence Principle, EP),” McCulloch explained. “If MiHsC is correct, then the EP is only an approximation (the small deviation from the EP due to MiHsC could not have been detected in torsion balance experiments, as I explain in the Discussion of my paper). As a result there may be implications for General Relativity since this assumes the EP is true (and therefore also implications for low-acceleration phenomena like the orbits of stars at the edge of galaxies). Inertia is important practically since it determines the sensitivity of an object’s motion to outside forces.”As McCulloch explains, the Tajmar effect is closely related to another odd observation: the unexplained acceleration of some spacecraft. For instance, when interplanetary probes fly by the (spinning) Earth, some of them undergo unexplained jumps in velocity. In a previous paper, McCulloch showed that the MiHsC model agrees fairly well with these flyby anomalies if a spacecraft’s acceleration is determined relative to all the particles of matter in the spinning Earth. He also showed that the model could explain the Pioneer anomaly: as the two Pioneer spacecraft flew out of the Solar System, they slowed down more than predicted, which can be attributed to the spacecrafts’ small decrease of inertial mass, which increased their acceleration toward the Sun.In the current paper, McCulloch suggests a way to test his model’s validity for explaining the Tajmar effect. His model predicts that reducing the mass of the rotating ring by a factor of 10,000 would result in a decrease of the effect with distance. He hopes that Tajmar’s group will try this test with lighter rings using their existing equipment. If McCulloch’s model holds up, it could potentially prove useful.“Once the cause of something is known, then it may be controllable,” he said. “The control of inertia could be useful. For example: Can we generate Unruh radiation to change the inertial mass of an object and thereby move it? I have discussed this possibility in previous papers (e.g., EPL, 90, 29001).” ( — When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why. The anomalous acceleration was discovered in 2007 by Martin Tajmar at the Space Propulsion group at the Austrian Institute of Technology in Seibersdorf, Austria. So far, the effect has only been observed in this one laboratory. Since then, scientists have been looking for an explanation for the so-called Tajmar effect. Copyright 2011 All rights reserved.

DOI: 10.1209/0295-5075/95/39002 Citation: Gyroscope’s unexplained acceleration may be due to modified inertia (2011, July 26) retrieved 18 August 2019 from In a recent study, Michael McCulloch of the University of Plymouth in the UK has shown that a model that he previously proposed can predict the small unexplained acceleration. His results are published in a recent issue of Europhysics Letters.“[Laser gyroscopes] work by sending light around a circle in both directions, and then measuring the interference of the two opposing light waves,” McCulloch told “When the gyro is spun/accelerated, the interference pattern changes detectably.” Commercial laser gyroscopes that operate this way are currently used in aircraft and missiles for orientation and stabilization.In this study, McCulloch suggests that the gyroscope’s observed acceleration stems from a change in its inertial mass and an attempt to conserve momentum with respect to a supercooled rotating ring. Tajmar’s experiments used rings that were cooled to 5K and made of a variety of materials, such as niobium, aluminum, stainless steel, and TEFLON.McCulloch proposes that the gyroscope’s inertial mass is determined by surrounding Unruh radiation that is modified by a Hubble-scale Casimir effect. In the model, the Unruh radiation is generated by the gyroscope’s acceleration relative to every other mass in the universe, such as the fixed stars in the sky and the cold rotating rings. The Hubble-scale Casimir effect is an effect in quantum field theory that, in this case, prohibits the generation of longer Unruh waves, and so indirectly affects the gyroscope’s inertial mass. McCulloch calls this model “modified inertia due to a Hubble-scale Casimir effect” (MiHsC) or simply “quantized inertia.” When the gyroscope is at room temperature, it is surrounded by short-wavelength Unruh radiation, and its inertial mass is close to its gravitational mass. When its surroundings are cooled, the gyroscope’s inertia becomes more sensitive to the small accelerations of the fixed stars. The wavelengths of the Unruh radiation become longer, and are prohibited by the Hubble-scale Casimir effect, causing the gyroscope’s inertial mass to decrease to less than its gravitational mass. However, when the supercooled ring begins to rotate, the ring’s larger accelerations cause the Unruh waves to shorten so that fewer waves are prohibited, and the gyroscope’s inertial mass increases.last_img read more
