An astronomical-optics researcher whose active optics methods use controlled elastic deformation to produce accurate optical surfaces. A mirror can be polished while stressed and then released into a desired aspheric shape; related methods change curvature during use. His work connects elasticity calculations with telescope and spectrograph construction, reducing fabrication errors while keeping optical designs relatively simple.[ref]

P. de Bernardis coauthored maps of cosmic microwave background temperature variations at four observing frequencies. Their angular power spectrum peaked near multipole , supporting a spatially flat cosmological model within the paper's cold dark matter interpretation.[ref]

J. M. Dziedzic coauthored an optical trapping experiment in which a single laser beam held dielectric particles in water. The observed size range extended from approximately nm to micrometres, illustrating the range of objects accessible to optical tweezers.[ref]
Observation of a single-beam gradient force optical trap for dielectric particles by Arthur Ashkin and others. Optics Letters 11 (1986), pp. 288–290: printed author J. M. Dziedzic and abstract reporting single-beam trapping and particle-size range.
J. Aasi coauthored the LIGO instrument paper describing its advanced detectors. Their -km Michelson interferometer arms use optical cavities to increase interaction with gravitational waves; improved isolation, suspended mirrors and optical design reduce competing sources of noise.[ref]
Advanced LIGO by J. Aasi and others. Abstract and detector configuration; the collaboration standard reference identifies the published instrument paper as J. Aasi et al. (2015).
B. P. Abbott coauthored the collaborative analyses of GW150914. Fitting general relativity waveforms to LIGO data constrained the properties of the merging binary black hole.[ref]
Properties of the Binary Black Hole Merger GW150914 by B. P. Abbott and others. Author list and abstract: coherent analysis across the detector network using compact-binary waveform models and inferred source parameters.
A companion study converted detector control-loop signals into gravitational wave strain, with an optomechanical response model and independent checks of its measurement uncertainty.[ref]Calibration of the Advanced LIGO detectors for the discovery of the binary black-hole merger GW150914 by B. P. Abbott and others. Author list and abstract: time-domain calibration filters, optomechanical/feedback response and validation with radiation-pressure actuation.
Masahiro Kito contributed to establishing p-type semiconductor behavior in magnesium-doped gallium nitride. Hiroshi Amano's account credits Kito with Hall effect measurements after low-energy electron beam treatment, providing stronger evidence for the conduction type than the initial hot-probe test.[ref]

A theoretical physicist whose work relates flavor symmetry to patterns of neutrino oscillations. His 2008 analysis asked which finite groups can enforce a particular mixing pattern independently of arbitrary interaction strengths. This turns a proposed pattern of quantum mixing into a constraint on a model’s symmetry, rather than adjusting each matrix entry separately.[ref]

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
