Today we've launched our book "Atlas of Fourier Transforms". It has been a two year passion project led by Miti Shah, a student in our lab. It is uniquely comprehensive and suitable as a coffee table book or advanced research reference. The full pitch is on Kickstarter.

"Quantum mechanics is just thermodynamics in imaginary time." It sounds like a hand-wavy, quasi-philosophical statement. But with a brief dive into the relationship(s) between hyperbolic and parabolic PDEs, it becomes possible to formalize it mathematically. (1/16)

1. Hot off the press! Our paper “Indirect measurement of atomic magneto-optical rotation via Hilbert transform” doi.org/10.1088/1361-6… In this thread I shall explain how useful Hilbert transforms are for processing laser absorption spectra

Hi, I’m David Brückner David Brückner. I’ll take you through how cells in a tissue can use information distributed by biochemical gradients to make decisions, and how we can measure such positional information. x.com/EpiMechFC/stat…

Here is my collection of cheap and open optics/photonics/positioner so far: OpenFlexure OpenUC2 Low-cost, open-source XYZ nanopositioner for high-precision analytical applications Open Photonics: An integrated approach for building a 3D-printed motorized rotation stage system

Where is the optical axis? Finding it can be critical to building microscopes. Here's the back reflections at ~15cm from a collimated ~1mm⌀ 532nm laser aligned into the back of Nikon 40x0.95 air objective. Radially symmetric/concentric interference rings indicate good alignment.

This paper demonstrates for the first time that the molten salt can be a media to synthesize quantum dots. This paper also presents the first luminescent colloidal GaAs quantum dot. Redox chemistry is a powerful tool to achieve this nice materials! science.org/doi/10.1126/sc…

One of the most badass Fig. 1 I have ever seen. (and the reference cited is his own lab notebook)

Some exciting results to share! The MagLOV and related proteins from Andrew York and Maria del Mar Ingaramo are quantum. We measured 4% optically detected magnetic resonance contrast in living bacterial cells at room temperature. biorxiv.org/content/10.110…

Speaking of mathematical consistency. While you want a physical theory to be mathematically consistent, it's not necessary for it to be useful. The standard model without the Higgs eg violates unitary beyond a certain energy. That's not consistent. It's still a useful theory to

A first-order, disorder-driven, superconductor–insulator phase transition is demonstrated. This is in contrast with the usually observed second-order transition and highlights the role of Coulomb interactions between preformed Cooper pairs. nature.com/articles/s4156…

You might think our daily life is still far from the world of quantum, atoms and electrons, but sota security CMOS camera is not that far from counting single photons (read noise ~< 0.3 electron rms). When you do it's called a quanta image sensor (QIS), and you can resolve single

If you tell me in 2015 that in 10 years we'll be talking to AI in an online FDTD simulation to help setting up the model, and run & get results within 30 seconds, I'd ask what you were smoking give me some of that cope. (not sponsored by flexcompute. The AI assistant is still

ÅNGSTRÖM-RESOLUTION IMAGING OF CELL-SURFACE GLYCANS  🧬🎨🍬 The glycocalyx, our cells' sugar coat, holds secrets in immunology, cancer, viral infections, and more. Visualizing its molecular architecture was impossible… until now. #glycotime #microscopy biorxiv.org/content/10.110…

A lens can perform the Fourier transform! 🔍 This is the 4F system: the first lens converts an image into its frequency components, and the second lens reconstructs it. By adding an aperture at the Fourier plane, we can filter out high frequencies. #Optics #Physics #b3d

🔥Super excited to share our latest work out now in Science Magazine science.org/doi/10.1126/sc… This paper describes the discovery of "glycosyrin" a small molecule produced by the bacterial pathogen P. syringae to manipulate glycobiology inside host plants during infection.🧵1/20
