Note to NIST about gold Au typos The Thermal Expansion of Pure Metals

Hello, I was looking at The Thermal Expansion of Pure Metals: Copper, Gold, Aluminum, Nickel, and Iron at It has a spreadsheet.  In the “Au data” sheet There is a temperature 38136.  I think that ought to be 381.36. The value for 157 centigrade, 37.3417?  Should it be 0.00373417? The value at 34.6 centigrade,

Notes related to A MEMS Resonant Lorentz-Force Magnetometer with Both Structural Topology Optimization and Parametric Pumping for Q-Factor Enhancement

A MEMS Resonant Lorentz-Force Magnetometer with Both Structural Topology Optimization and Parametric Pumping for Q-Factor Enhancement at Yuan, Life has been interesting lately. I get to work on some of the most interesting questions. Just now I am tracing down some laser wakefield capillary tube x-ray sources. The laser diode groups seem to have gotten

Comment on Video Demonstrating Convection, and approaches to understanding and visualizing

How to demonstrate convection at The simple materials are good, but you, yourself, did not explain what you were expecting, where the students and demonstrators were supposed to focus their attention. You said (don’t use purple shirt) and for this short video, why did you not go change your shirt and record it again? Or,

Comment on Making Petrified Lightning – application to solar system colonization, global needs and new industries

TheBackyardScientist,  Making Petrified Lightning …with electricity? at 3D printing metal. You can use metal or glass powders, control the current, and randomly choose next points – probably run on Arduino. You have all the skills and stuff mostly. Maybe someone already suggested. You might invent a way for YouTube viewers to work together, combine
