The Team That's Indifferent To Your REBUKING...😅🤣

7/100 days of productivity - life update

Hello everyone, I have gone offline for past few days... I have had family business to sort out. Honestly it was difficult, but most of it went well! A lot of long lasting family issues got resolved in the past few days, and it was a breath of fresh air! That being said - I have received news regarding my housing and financial situation that are... less than pleasant to hear. Fortunately, they won't impact me or my studies right now, but I have to plan for the future. So focusing on that is my objective as of right now. The next three months of my life are going to be extremely difficult, and I will have to correspond with people who... were horrible to me both in the past and right now, but I can manage. That means I will be extremely busy... That's why I've decided to rest for this weekend! So yeah. Thank you to anyone who decides to read this! Take care-

i hate this fucking "i'm just a girl" brand of feminism bc it is so easy for young women in their 20s who are afraid of big changes and personal growth to revert to depending on their gender and the associated fragility of it so that they can make it through life when really they're just trapping themselves in a position where they cannot and will not grow out of that fear.

Taking a slight tangent from classical optics, I decided to delve more into non-linear optics.

As someone who never had to use Gaussian form of Maxwell's equations, never used Tensors, and had never used Einsteins notation for summation; let me just say the algebra of the book proved to be a hard nut to crack!

What am I learning about? Anisotropy! Who knew that the direction at which you observe/propagate through a material such as a crystal plays a role in the material properties you will experience!!

I still don't believe you can determine eigenvalues and eigenvectors for an arbitrary 3x3 permittivity matrix (I need to use numerical examples to really see it) and that there exists rotational matricies that let us make the math all neat and proper.

But, slowly and with growing pains, I am continuing to slowly tread the waters of this fascinating topic!

sometimes you run into something that just overturns your understanding and builds a new, more coherent picture. this is one of them.

they taught us about diffraction theory at uni - Fresnel, Fraunhofer all of that, we did experiments with lasers - but it never occurred to me to analyse lenses in terms of diffraction. it makes so much sense now! i was never entirely satisfied by the ray approximation to light, so seeing what's really going on in the lightfield and how you can use a diffraction plate as a lens, with each ring contributing higher order Fourier terms to the image, is like. crazy cool.
