AI Thread Summary
Electron Ptychography Imaging is a groundbreaking microscopy technique that eliminates the need for lenses, enabling the creation of ultra-high-resolution images. This method reconstructs images from electron waves scattered by samples, overcoming limitations associated with traditional microscopy, such as blurriness from glass lenses and visible light wavelengths. It has the potential to image live cells without causing damage, opening new avenues in biological research. The technique may also influence the adaptation of electron microscopy methods to x-ray imaging. Overall, Electron Ptychography Imaging represents a significant advancement in imaging technology with diverse applications.

Looking forward to all the applications this will be used in!

A new microscopy method that ditches lenses altogether could create the highest-resolution images ever seen. The system reconstructs an image from the electron waves scattered by a sample, and has no fundamental experimental limits imposed by constraints like blurry glass or wavelengths of visible light. It can even be used to image live cells without harming them.

That's awesome!
 
This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
