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. Since 2009, I can add photolithography for the semiconductor industry to that, or at least a tiny bit of a particular aspect of it. Although I do not have a formal medical background, I think I'm fairly skilled in spotting pseudoscientific nonsense that is touted by commercial websites and subsequently finds its way into health-related Wikipedia articles.

Contributions

This section is horribly incomplete and out-of-date.

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.

Older contributions

For historical reasons 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
