1. In a paper “On the Atomic Weight of Thallium,” presented to the Royal Society June 18, 1872, after describing a balance with which I was enabled to perform weighings of apparatus &c. in a vacuum, I noted a peculiarity in relation to the effect of heat in diminishing the apparent weight of bodies. I said, “That a hot body should appear to be lighter than a cold one has been considered as arising from the film of air or aqueous vapour condensed upon or adhering to the surface of the colder… Expand
The Wave Theory of Heat: A Forgotten Stage in the Transition from the Caloric Theory to Thermodynamics
R E S EAR C H on thermal "black-body" radiation played an essential role in the origin of the quantum theory at the beginning of the twentieth century. This is a well-known fact, but historians ofExpand
The pressure of light: The strange case of the vacillating ‘crucial experiment’
DOES A BEAM of light carry a momentum and hence exert a pressure on any absorbing or reflecting body on which it falls? This straightforward question seems to admit of a straightforward decisionExpand
Experimental and Computational Observation of Radiometric Forces on a Plate
.Reynolds also took part in the experiments conducted by Schuster 7 that turned up the first experimental evidence of gas forces being the dominant cause of the radiometric effect. In thisExpand
Thermophoretic Force Measurements using a nano-Newton Thrust Stand
Thermophoresis is a rarefied gas phenomenon characterized by the migration of particles in a fluid with a macro level temperature gradient. This particle migration occurs in the direction of the heatExpand
William Crookes and the quest for absolute vacuum in the 1870s
Summary This essay examines the technical evolution and scientific context of William Crookes's effort to achieve an absolute vacuum in the 1870s. Prior to late 1876, along with interrogation of theExpand
An Experimental and Numerical Study of the Final Zero-Flow Thermal Transpiration Stage
By just applying a temperature difference to a micro-system filled with rarefied gas, it is possible to engender a displacement or a compression of the gas in the temperature gradient direction. ThisExpand
Photophoresis of aerosol particles with nonuniform gas–surface accommodation in the free molecular regime
Abstract The problem of calculating the photophoretic force acting on an aerosol particle, with nonuniform distributions of accommodation coefficients over the particle's surface in a rarifiedExpand
Experimental and Computational Observation of Radiometric Forces on a Plate (Postprint)
Abstract : The radiometric force on several configurations of heated plates placed in a stagnant gas is examined experimentally on a high resolution thrust stand and numerically using the directExpand
Experimental and Computational Study of Area and Perimeter Contributions to Radiometer Forces
The relative contribution to the radiometric force of the area and perimeter of the vane is studied experimentally and numerically. Experimentally, a circular vane, a low‐aspect rectangular vane, andExpand
Microstructure actuation and gas sensing by the Knudsen thermal force
The generation of forces and moments on structures immersed in rarefied non-isothermal gas flows has received limited practical implementation since first being discovered over a century ago. TheExpand
