Question about Israel ... Well... A picture I found and curious who the guy is...was in a well-known members sig too

[웃 910]

So I was just looking through a friend of mines pictures on Facebook. We went to the same middle and high school. He's been living in Israel the last several years.

Then I clicked on one of his friends profiles (was a random guy that was tagged in his pic). He is also living in Israel. Was just scrolling through some of the pics.

Then I came across this picture in the dudes album:

I recognized immediately that this same picture was in Scandal's profile. I went to confirm and this pic has always been in Scan's signature:

Obviously they are the same person. So I am wondering who the guy is? Or at least what does that say in Hebrew?

I always thought it was Scandal's son! Anyone have any clue?

Thanks for that link, I notes the photo on Scandals sig too and kinda wondered who he was.

With the unreasonable laundry list of demands to gain his freedom..... it's not looking good.

I think in Hebrew, scandal's siggy states "Free Gilad Shalit"--scandal may be friends with Shalit's dad (speculative only).

[Harpa Timsah 13,258]

Gilad Shalit is an Israeli soldier being held captive by Hamas (for about 5 years now). He is only 22/23 now, so he was 18 when he was captured. He was captured in Israel by Hamas people digging tunnels under the border and popping up on the other side.

The first photo says "I, too, am waiting for Gilad."

The second is "Release Gilad." The last four letters in both photos is the same, if you notice... they say Gilad, and are sort of like G (i) L A D (Hebrew doesn't have a lot of vowels).

Here is more info - but google will get you far. http://news.bbc.co.uk/2/hi/middle_east/6238858.stm

Where is Scandal?

[_Simpson_ 250]

Have there been any reports that he is still alive?

[_Simpson_ 250]

Read the article and as of 2009 it looks like he is still alive.

Scandal was good for dodging questions on here and that was about it. I rocked his world in god only knows how many threads and all he did was run for cover.

Scandal was/is the smartest guy I have ever met. He was a walking encyclopedia. Very well rounded in all subjects. It is rare to have a Ph.D. level of knowledge in mathematics, science, and history. But he seemed to.

I'll give you the benefit of the doubt and say you are really smart. But even close to as smart as Scandal --->

He was a complete genius.

Show me a post of yours that looks anything remotely close to this:

Hal - the weather in Chicago was pretty amazing yesterday, wasn't it? It was almost pitch darkness at 11AM yesterday, looked like the end of the world!

Regarding the change in density of atmosphere (not just C02, but all the atmospheric gases) at lower altitudes as compared to higher ones -this is accommodated by a single continuous model with one fluid regime. The mass and momentum continuity expressions allow for a non-constant fluid density. As I said before, it's the divergence which must be zero in an incompressible flow. There can be (and is) a non-zero convection term.

Bill, you are quite right at higher and higher elevations when you get to a rarified atmosphere at some point the fluid regime cannot be modeled as an Eulerian flow and needs to be tracked as particulates using statistical mechanics.

Like any model, N-S makes assumptions about where it is being employed. If those assumptions no longer hold true, the model is not appropriate. What I presume people do when looking at problems that span the lower atmosphere to higher regions is to do an asymptotic matching between N-S based solutions below and statistical mechanics ones above.

Since there appears to be some genuine interest here regarding N-S, here's a brief laymans overview of its significance and meaning.

There are 2 key assumptions behind it: (1) a "fluid" consists of particles. The particle sizes and the inter-particle distances are much smaller than the spatial dimensions of the solution space. Hence, molecules of H2O or CO2 or N2 are much smaller than vessels containing them or over which they flow (beer bottles, centrifuge tubes, bathtubs, airfoils, turbines, oceans, atmospheres).

(2) The basic conservation principles of physics: conservation of mass, of momentum, of angular momentum (for rotating flows), of energy, and of enthalpy apply.

Due to (1), we assume an averaging approach is valid. We can take a volume of space (imagine a cube 1cmX1cmX1cm) and consider all the fluid within that cube, and flowing through the surfaces of the cube. If you now take the limit (mathematically) and shrink that cube down to an infinitesimal size, that is the idealized fluid "particle". And the model will hold true as long as the fluid properties are smoothly continuous at the scale of that particle.

Due to (2), we can now write down balance equations.

Conservation of mass is a simple statement that you can't make something out of nothing. Hence if you have a closed system, no matter how the fluid moves about the total mass must be constant. Or if it's not a closed system, then the total mass at a given moment must equal the mass that was there an instant ago + the mas that was transferred into the bounding surface of the system - the mass that transferred out through the bounding surface. Let's apply that very principle to each of the infinitesimal elements we defined in (1). Each little tiny cube will have its own mass transfer balance. And then we'll sum up (i.e. integrate) over all the little tiny cubes.

So let's express mathematically the rate of change of fluid momentum to the convective flows across the surface:

First term is time-rate of change of "stuff" (density) inside the fluid volume. Second term is the convection - the rate of "drift" of "stuff" over the membrane of the surface. It's literally the rate of change (vector spatial derivative) of the velocity vector of the fluid (v) as that "current" drags stuff in and out of our little box. Clearly, the sum of the two must be identically zero - that's conservation of mass.

We can do a similar thing for momentum conservation. Newton's second law tells us that applied force is related to the accelaration, F=ma. But 'a' (acceleration) is the change in velocity, dv/dt. And in fact (m * dv/dt) is really more generally d(mv)/dt (since the mass density is not always constant), which is dp/dt (where p= momentum = mv). So the more general statement of Newton's second law is F= dp/dt , the applied force is equal to the change in momentum.

When you "plug in" F=dp/dt into the convective model for an infinitesimal volume, you get:

The first term is the time rate of change of momentum (the mass 'm' is now normalized as the density per unit volume rho).

The second term is the convective term, just as before in the mass balance, where we have the fluid velocity v 'dragging' momentum in and out over the bounding surface. The 'vv' expression is a tensor product - since these are both vectors. Finally, 'Q' is the applied external force, the famous 'F' of Newton's F=ma. It is both a generalized external body force (e.g. gravity), and any inter-particle forces (e.g. frictional viscosity) between neighboring fluid particles.

Since p is a vector quantity, so in 3 dimensions we have 3 separate balance equations, one in each dimension. (The momentum in a closed system along each of x,y,z axes must be independently conserved). Thus the equation above is really 3 separate scalar equations all expressed as a single vector equation.

We now have 4 independent variables to be solved for - the density rho, and the velocity components in each dimension (for Cartesian coordinates, typically expressed as u,v,w). These variables are in fact field functions, they vary over the continuum. I.w u is u(x,y,z,t).

And we have 4 equations (one mass balance, 3 momentum balance).

Consequently we should be able to integrate and solve for the 4 field functions, assuming suitable initial and boundary values. Note that until here the system is first-order (we have only first derivatives in time and space, no second derivatives).

However -- the missing step is 'Q'. We need to account for fluid viscosity. In 'simple' Netownian fluids, we have a linear stress/strain relationship. Consequently Q becomes a term that associates a constant viscosity and a second order derivative of the velocity field.

But in other settings things get more complex, and we cannot solve mass/momentum balance on their own, but rather need to introduce the energy equation to be able to get a complete solution for all field variables.

As I said, I'm recalling this from 20 years ago, plus quick Google hits. I may be off on some statements, but generally it's the outline.

N-S is a system of coupled non-linear PDEs (Partial differential equations) in space and time. The equations are solved (usually numerically, in some rare cases closed form solutions exist for simple geometries) to provide the key field functions of interest - density and velocity fields.

The equations Bill provided at the top are N-S expressed in a particular spherical coordinate system suitable for climate studies of Earth. That's why you get the trig expressions appearing, it's due to using (r, theta, phi) coordinates rather than Cartesian (x,y,z).

N-S is fascinating because of the non-linearity and tight coupling of the equations.

Other famous PDE systems such as Schrodinger's Equation (in Quantum Mechanics) or Black-Scholes (in option pricing theory) and even Maxwell's Equations (in Electromagnetism) also have their own inherent beauty. But in my (very limited) knowledge of all of these, Navier-Stokes are by far the biggest ###### to solve numerically.

Enough!

I never said he wasn't smart, I said he dodged questions time after time ...especially in regards to Israel. Soffyia is no dummy by any standards, yet we have seen her do the same thing.

Without a doubt, Brother Scandal is one extremely sharp fella.

AJ outed me, and directed me to this thread.

I'll deal with him later

Meanwhile, I'll answer some of the questions and points raised here.

Obviously they are the same person. So I am wondering who the guy is? Or at least what does that say in Hebrew?

I always thought it was Scandal's son! Anyone have any clue?

No, he's not my son. He's Gilad Shalit, as others have noted.

I think in Hebrew, scandal's siggy states "Free Gilad Shalit"--scandal may be friends with Shalit's dad (speculative only).

No, I don't know anyone in the Shalit family personally. They do come from Nahariya, just north of where I lived in Israel, in Haifa. The whole country feels an affinity for the Shalit family and their ordeal. It cuts across the political and religious spectrum in Israel. The closest thing in recent American history I can think of might be the death of Pat Tillman to friendly fire.

Gilad Shalit is an Israeli soldier being held captive by Hamas (for about 5 years now). He is only 22/23 now, so he was 18 when he was captured. He was captured in Israel by Hamas people digging tunnels under the border and popping up on the other side.

Where is Scandal?

I'm around, I just gave up on VJ. Too much inanity, much too much nastiness, and most of all too many mods shutting down the parts I most enjoyed. Closing the IEA thread was the last straw. If this is the kind of site Ewok and the mods want to have, they can have it. I have no use for it.

Wow, LI

That's all very nice of you to say. I think I handle my own intellectually, though not even close to genius. I do appreciate and enjoy (respectful) debate about a wide variety of subjects. That part of VJ was always fun for me.

Without a doubt, Brother Scandal is one extremely sharp fella.

Thanks Mark.

LI, Bishop - the good vibes are mutual. I hope all is well with you and yours.

He has a mancrush on you. The least you could do is reciprocate.

What if I did my best Meatloaf imitation and told that "I want you, I need you, but there ain't no way I'm ever gonna love you..."

That might just turn him on even more.
