It used to be that most of the scientists from US universities I met at international physics conferences or summer schools were green card holders or recent immigrants. There were hardly any american born ones. Did that change in the last 20 years or does the show slightly misrepresent that ratio.
I am asking because in his way Sheldon reminds me of some Russian physicists I used to know.

that I used for my paper 15 years ago. It is on a tape, that is somewhere in a drawer, that I have no tape drive for. On the other hand, the LaTeX file and the C and FORTRAN programs I used to evaluate and create the data and write the paper are still on a hard drive that is running on a computer in my network and I can access it right now. I probably can*t compile the the program without change (was written for Solaris and DEC machines) and maybe not even run LaTeX on it without getting some of the included styles, but still it is there.
Since my work was in theoretical physics and numerical the loss of the raw data is probably not as bad as long as you still have the software, but I guess for an experimental physicist the problems would be much greater to keep the massive amount of data they sometimes have and if lost to reproduce the data.

the nvidia-settings tool to set up 4 monitors on my GTX670, there is no problem with speed and I get hw accelerated 3d on every screen. The driver is NVidia's 310.19. I used the TwinView Option on the Layout selection screen and could put the monitors into the wanted configuration with the GUI. I can move windows between the monitors and xfce gives me panels on the separate monitors.
The screen section in the xorg.conf looks like this:
Section "Screen"
        Identifier "Screen0"
        Device "Device0"
        Monitor "Monitor0"
        DefaultDepth 24
        Option "TwinView" "0"
        Option "Stereo" "0"
        Option "nvidiaXineramaInfoOrder" "DFP-0"
        Option "metamodes" "DFP-0: nvidia-auto-select +0+0, DFP-1: 1920x1200 +1920+1080, DFP-3: nvidia-auto-select +1920+0, DFP-4: nvidia-auto-select +0+1080; DFP-1: 1920x1200 +0+0; DFP-1: 1920x1200 +0+0"
        SubSection "Display"
                Depth 24
        EndSubSection
EndSection

and the server layout:

Section "ServerLayout"
        Identifier "Layout0"
        Screen 0 "Screen0" 0 0
        InputDevice "Keyboard0" "CoreKeyboard"
        InputDevice "Mouse0" "CorePointer"
        Option "Xinerama" "0"
EndSection

if you forget part of the energy-momentum tensor when you transform your coordinates from a stationary into a moving frame of reference.
Special relativity really cannot "clash" with the Lorentz force law, because it is based on the Lorentz invariance of Maxwell's equations. I think a "paradox" like this keeps coming up ever so often in discussions of special relativity, form people who don't understand it. I just don't see how PRL can accept such a paper.
I admit it would make a nice problem for a physics test, but not much more.

I saw the camera on NHK World and it is not what you may think is camera sized. It is a big cube with about 1 m sides. It also includes a small optical camera, so that you get a composite of the visual picture and the gamma radiation distribution. It is supposed to be used to check the buildings in contaminated areas and see where the radioaktive material is located.

Isn't it the purpose of the patent system to make those inventions available for research in exchange for a monopoly?

and I run Linux on all of them.

They already did that for the last world cup.
You had to register for your ticket and you could not give it away. So they could check if you are the person that ordered the ticket. I don't remember if they already had a chip in the ticket, but when you can check the serial number against a database, you really don't need a chip.
