What else can I help you with?
Do electrons have negative mass?
No. There is really no such thing as negative mass. Even antimatter has mass, which is always a positive (that is, greater-than-zero) quantity. There is, however, the concept of effective mass or apparent mass, which can be negative. When an object is submerged in water, its apparent weight is reduced by an amount equivalent to the weight of water it displaces. For example, if a 10-pound rock is dropped into a bucket of water and displaces one pound of water, the effective weight of the rock under water is nine pounds. But what if you submerge something much less dense than a rock -- say, your little brother's head -- in the bucket? Okay, forget that. Let's says a big ball of Styrofoam, instead. (Not as eco-friendly but less violent.) In that case, the weight of the water displaced by the ball will be far greater than the actual weight of the ball, so when you subtract the weight of the water from the weight of the ball, you'll get a negative number. In other words, the effective weight of the ball under water will be negative, and the ball will tend to rise. It will fight your efforts to submerge it, much as your brother would if you submerged his head (but for reasons other than mere buoyancy).
What is an operator in quantum mechanics?
In the dirac view of quantum mechanics, operators are the center of analysis. An operator is some mathematical operation that acts on the wavefunction (psi) which returns an observable. Lets look at some examples: say psi=exp(ik(dot)r)*exp(iomega*t) (which is the case for a free particle) the momentum operator is the -ihbar gradiant applying this to our psi- we get hbar k. This is called the observable. perhaps more familiar the energy operator which would likewise return hbar omega. Now doesn't that look familiar! Interestingly enough, these two examples point out that the conservation of momentum and energy stem from the laws of physics being invariant, regardless of position and time.
What is a QFT robust-control toolbox?
It is a special tool box available with matlab 5.0 for designing QFT controller
What does QFT stand for?
There are a few acronyms see link below.
How is quantum field theory (QFT) affected by the curvature of spacetime?
Quantum field theory (QFT) is impacted by the curvature of spacetime through the concept of curved spacetime in general relativity. In curved spacetime, the behavior of quantum fields is influenced by the curvature, leading to modifications in the way particles interact and propagate. This interaction between QFT and curved spacetime is crucial for understanding the dynamics of particles in the presence of gravitational fields.
How many 35qft in one meter?
No idea what a qft is but 1 metre = 0.094 lots of 3 feet.
What are the solutions provided by Schwartz in his Quantum Field Theory (QFT) book?
Schwartz provides solutions to problems in Quantum Field Theory (QFT) by using mathematical techniques and physical principles to describe the behavior of particles and fields at the quantum level. These solutions help to understand and predict the interactions of particles and fields in the universe.
How much of an acre is 13004 qft?
One acre has 43,560 square feet. Divide the number of square feet by that and you get the number of acres. This gives you an answer of .298 acres.
What is wave particle duality of light?
The theoretical wave particle duality of light states that a particle of light (a photon) exerts the characteristics of a wave and of a particle. This is a consequence of the nature of light; a single 'unit' of light comprises of a photon and an electromagnetic field, which can consequently exert either (or both) the characteristics of a wave and the characteristics of a particle. Heisenberg's principle of uncertainty is, therefore, applicable to light 'packets', and indicates that either the momentum or the position of the particle will be measured less accurately as the accuracy of the other increases.It is considered a paradox. Einstein first proposed that Planck's 'Quanta' should also be applied to light. It was strongly resisted, but he eventually won his Nobel Prize for it. It is often misunderstood. Photon particles have only ever actually been observed at short ranges and with short life. They are however also assumed to travel from distant stars, which came back to bite Einstein as particle conservation is one of the obstacles for Unification of QFT with Relativity. Energy is wave oscillation, and particles are focussed oscillation, (and/or 'spin') seen as 'corpuscles'. They also behave and 'group' in a 'wave like' way at a macro scale, Youngs twin slip experiment, the wave ahead of the earths bow shock are waves consisting of many billions of particles, similar to the surface of the sea.
What is the significance of the optical theorem in quantum field theory (QFT)?
The optical theorem in quantum field theory is significant because it relates the probability of scattering processes to the total cross-section of particles interacting with each other. This theorem helps in understanding and predicting the behavior of particles in quantum field theory, providing valuable insights into the fundamental interactions of particles at the quantum level.
What is bio entanglement physics?
Bio entanglement physics - or theory (BET) - has it's roots in Quantum Field Theory. QFT is the idea, proven to a large degree, that if you wiggle a particle on this side of the galaxy, it's tied-pair-partner (very hard to describe in laymans' terms, sorry) will mirror that movement on the other side of the galaxy; at the same time. Einstein had great trouble with this, because it breaks the boundaries of the General Theory of Relativity, or E=mc2. He and two other well known physicists set up experiments to disprove the notion, and ended up proving it instead! The reason I bring these up is that QFT implies that information can, regardless of it's size or length, travel beyond the speed of light; indeed, instantly. BET attempts to utilise this information and understanding to prove that there is a link between living beings. In much the same way that fish - all at the same time - change direction in a school with no understanding of why the same direction was chosen by all the fish at once. The actions happen multiples of times faster than the bioelectrical pathways would allow. Or why you are thinking about someone and the phone rings; and it's the person you were thinking of. It goes further still. REGs, or random event generators, measure the frequency of the Earth's atmosphere. The Earth vibrates at a particular frequency which increases or decreases over patches of high energy intensity, like a large lightning storm, earthquake area.....or Tokyo! These REGs also picked up serious frequency fluctuations worldwide around events like Sept 11 2001, Katrina, Aceh Tsunami and the Iraq invasion. It appears that when human emotions are aligned, on a larger than normal scale, that the atmospheric frequency of the Earth changes - but more research is needed to entirely prove it. The evidence to date, however, is quite compelling. So this is BET in a nutshell - the desire to prove conscious interconnectedness. Aaron Sice - www.aaronsice.com.au
What tests are used to screen for TB?
Besides culturing in the laboratory, the two most common types of tests to screen for exposure to this disease are the Mantoux PPD tuberculin skin test, which is generally considered more reliable, and the older TB tine test, which is now rarely used
