In real life, my name is Han-Kwang Nienhuys. I have a background in physics and chemical physics, more specifically time-resolved spectroscopy and lasers. I know a few things about Netherlands and Sweden. Most of my professional scientific writing is in English, hence the en-5 level. For subjects not related to (chemical) physics, time-resolved spectroscopy, and lasers, I am an en-3.

I am mostly active here rather than in Dutch Wikipedia since I want my specialistic knowledge to be available to an audience that is as large as possible. Most Dutch people can read English, but the converse is not the case.

[edit] Contributions

Pet articles:

• Template:nutritionalvalue - I'm slowly adding nutritional data to food-related articles.
• Winemaking
• Laser-related: Chirped pulse amplification, prism compressor, EN 207, Femtosecond pulse shaping, Terahertz time-domain spectroscopy, Laser safety
• Optics-related: Triangular prism (optics)
• Physics: Poynting vector
• Misc: Potato cyst nematode
• Transfer-matrix method (optics)

Furthermore, I try to keep an eye on linkspam and evident (scientific) nonsense.

[edit] Older contributions

Some of the articles I contributed to in a time (2004) when it was very easy to add relevant new content to stubs and missing articles:

• Lasers: Laser, List of lasers, Nd-YAG laser, Ti-sapphire laser, dye laser, Laser safety
• Spectroscopy: Absorbance, Electromagnetic spectroscopy, Electron spin resonance, Molar absorptivity, Nuclear magnetic resonance, Spectroscopy, Spectrophotometry, Time-resolved spectroscopy, Transmittance
• Physics: Nonlinear optics, Speed of light
• Chemistry: Recrystallization, Supersaturation
• Mathematics: Eigenfunction, Orthogonal functions, Kramers-Kronig relations
• Sweden: Allemansrätten, Lund, Image:Lunds domkyrka.jpg
• Netherlands: Gouda cheese
• Color vision: Color, Gamma correction, Gamut, International Commission on Illumination, Image:Gamut.tar.gz, Image:Cie chromaticity diagram wavelength.png
• Miscellaneous science/technology: Binaural recording, Microphone, Microwave oven, Microwaving
