    There are some vendors that have a good variety of IMX sensors boards. Usually labelled Board Level MIPI camera, some with usable v4l drivers.

    I have worked half of my life in both fundamental and applied science, I know how this work. In particular you can refuse jobs you deem unethical. Why not funding energy transition…

    Oh yes, they had some of the best climate scientists back then. It’s somewhat a scale up of what the tobacco industry did, same strategies, etc

    When I was doing my phd, around 2 decades ago, I was often going to the library’s compactus to fish for a Phys Rev from the 80s. Back then papers were sparse and expensive. But the…

    It’s how gauge theories work: - fermions (charges) are in the fundamental representation of the gauge group, here SU(3) so 3 Colors - bosons are in the adjoint représentation, for …

    agreed, when you start needing the the hodge star, diff form loose quite a lot of their interest. i'd add it's quite nice in string theories for RR fields and coupling to D-branes,…

    from a theoretical physicist point of view, i find GA don't add much to the standard tooling ppl use, i.e. Lie algebras, Clifford and (sometimes) differential forms. while it's alw…

    Well congratulations, you just stated the equivalence principle that led Einstein to GR (you need special relativity and a bit of maths and you’re there)!

    I’m doing a bit of BREP for GIS and even in 2D with line segments only the problem is really non-trivial, a lot of edge (pun intended) cases to take care of. Type system helps enor…

    The beauty and power of the Noether Theorem is what pushed me to theoretical physics. I consider it one of mankind’s greatest achievement.

    i used MIPI sensors on jetson, and while the drivers were provided by the manufacturer we wrote a a python/c++ library based on V4L2 to acquire images
