here you are about thermal diffusivity of graphene measured with a non contact method http://iopscience.iop.org/article/10.1088/0022-3727/48/46/465501

Because neutrino's flavour eigenstates are superpositions of mass eigentates, a zero-mass eigenstate is not in contradiction with observation since the neutrino of a any given flavour would experience mass and time flowing due to mass acquired from the superposition of two massive and one massless states. Because probability of transitions depends only on ...

The displacement of 7.44° is clearly wrong. It is inconceivable that a torsion pendulum with a period of around 50 - 100 seconds could be displaced by such a large amount through the attraction of a couple of 2 kg masses. I have to conclude that other factors (air currents?), not gravity, were the cause of the displacement you observed. You really need to ...

High speed winds are accompanied by reduced air pressure So high pressure from inside the house pushes roof to low pressure and gets blown away.

Charged antimatter particles are stored using electric and magnetic fields in near vacuum conditions. (Near-vacuum conditions can be created on Earth) Anti-hydrogen is stored by exploiting its magnetic properties. (While neutral, it still has spin magnetic moment. The storage is done using strong superconducting magnets.) Antiparticles are easier to store ...

According to http://www.scienceinschool.org/2014/issue28/planck, All you need to calculate Planck's constant is Four LEDs emitting coloured light – one each of red, orange, green and blue. Choose LEDs w Four LEDs emitting coloured light – one each of red, orange, green and blue. Choose LEDs with a clear, colourless casing surrounding the LED, so that ...

A classic method of measuring focal length is with an interferometer rather than by imaging. This is because you can determine movement in conjugate points very precisely. For example, using the interferometer you can: Locate the front and back surfaces of the lens and measure their optical thickness by measuring the translation of the interferometer ...

First, you should be aware that while normal racers need a good deal of downforce, it is used to increase tire friction and allow tighter turns. The Bloodhound, by contrast, is not intended to turn at all when at speed - ideally the driver would never turn the steering wheel. It just gets out on the track, gets up to speed, clocks the necessary distance, ...

Here are some ideas to be considered: What was the position of the source, microphones and starter at the beginning of the experiment? To get a reasonable data the source should be already moving when passing the first microphone. Do you have a signal long enough (in time) Fourier analysis to be precise? Did you try that on more frequencies? If you don't ...

in my opinion, the concept of Planck Units sorta settles what "constants" might meaningfully vary from those that it doesn't matter because we wouldn't know the difference. express everything in terms of Planck Units. then $c, \hbar, G, \epsilon_0,$ and $k_B$ do not even exist to vary. they are all $1$ except (from convention) $\epsilon_0 = \frac{1}{4 ... 2 Charge is a conserved quantity. If the incoming photon on a molecule is of the appropriate energy , an electron can be kicked from a low energy level to a higher energy level .Since the charge of the photon is zero , the molecule remains neutral. If the energy of the photon is high enough the electron gets kicked out, the molecule becomes positively ... 4 I'd recommend testing with dye, indeed, but the usual wisdom is that a fluid near its boundaries moves approximately as those boundaries move: so, for example, if you're modeling a big parking lot during a hurricane, the wisdom says that the proper boundary condition for the wind speed on the pavement is to set it to zero, and let the simulation form its own ... 1 What they actually measure is the amount of charge produced as these particles interact with the material of the detector. From that and a understanding of how charged particles interact with the detector (PDF link) they deduce it's kinetic energy (with some degree of ambiguity at times). To get momentum you pair the energy measurement with either some kind ... 0 In addition to the physical constraints on size, one has to consider the fact that the parts of any machines will degrade. When comparing a conventional machine to the brain, you need to consider the self repair and also the fact that the system is supposed to be copied to produce the next generation. The system has to be reproducible from scratch. If you ... 3 Although it isn't possible to answer your question, as the Human brain doesn't evolve its physical appearance in short time spans comparable to Moore's Law, I found some information that may help with the gist of your question. There are many differences between the human brain and a computer that make a comparison between their potentials difficult. ... 2 The rate of temperature is obviously just the rate of solvent loss due to evaporation multiplied by the latent heat of vapourisation. The trouble is that I doubt there is any way of estimating the rate of solvent loss without actually doing the experiment. It will be dependent on lots of parameters related to the geometry of your apparatus e.g. bubble size. ... 0 Air viscosity is not enough to be noticed by moving mosquito. But for it's wings air viscosity is important thing, not because their size, but speed. 14 Moore's law from the Wikipedia article: Moore's law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years (since the invention of integrated circuits). His prediction concerned the rate at which the density of transistors in circuits increased with time. So I'm not sure it makes sense to ... 0 Just imagine yourself shrunk down to the size of an insect. The air would "feel" the same but because of your mass and because you have no special organs to grip surfaces, you would feel constantly thrown around by tornado level winds caused by the swing of a regular sized human's hand. Insects are specially designed to handle these frequent gusts of wind so ... 0 An oscillating magnetic field always induces an oscillating electric field. So, the "magnetic field oscillating at radio frequency" is just shorthand for a radiofrequency electromagnetic field: both electric and magnetic fields are present. I believe the manual chooses to emphasize the magnetic field because it is the magnetic field that couples directly ... 22 What you need to compare when looking at bodies of different sizes and asking how the forces relate, is in general, the Reynolds Number as you included in your question. This is defined as: $$Re = \frac{u L}{\nu}$$ where$u$is the fluid velocity,$L$is a representative length scale and$\nu\$ is the kinematic viscosity of the fluid. This can also be ...

Your thought about feeling the water viscosity seems along the right lines, with the small modification that flight is easier to insects than swimming is to humans. One consideration, though, is an entity's limbs and their capacity to influence personal position: Insect legs and antenna may feel less rheological resistance and drag in air than ours would ...

Viscosity of air will be same for both fly and human. In the case of flies, from the point of view of the fly, it would seem to it that the viscous force is very high as it keeps the fly afloat. In case of humans, such viscous forces are negligible. So we don't notice it. If you want to scale up the insect flying "experience" to the human level, think about ...
