The uncertainties in the computed values result principally from scaling errors in the Faraday polarization rotation angle and from horizontal gradients in the ionosphere; they typically total less than 卤600 electrons/cm. A number of concentration profiles are shown and are compared with direct probe...
The article discusses research on rocky planets called super-earths that was conducted by Guillaume Morard of the Institute of Mineralogy and Physics of Condensed Matter in Paris France, and which found that the super-earths may be completely solid and may not be suitable for human life since th...
What is an example of a subatomic particle? Is a proton a subatomic particle? What particles are outside the nucleus of the atom? What is the charge of an up quark? What subatomic particles (protons, neutrons, and/or electrons) are found in the shells (orbits)? What subatomic particle ...
In January 2019, NASA captured an image of Antarctica’s Brunt Ice Shelf as it neared a substantial break that will release an iceberg twice the size of New York City. The crack, at the top right of the image, is called the “Halloween crack,” as it first appeared in October 2016...
[…] I am planning to have a conductor to the center of the mass of atoms. There would be one atom that makes contact, we wouldn’t even have to see it. Well, the balls, the atoms by the time we get thorugh all the electrons actually have the same… we find with the electron ...
In this he attributed certain nebular spectral lines to a primitive type of atom which he named nebulium. This he imagined to consist ofa small central massive positively charged nucleus with four electrons travelling around it on the same circular orbit. He was thus enabled to account for ...
Dozens of comets are discovered every year. A great majority are tiny iceballs in unfavorable orbits that never rise above magnitude +10 and are thus of little interest to backyard observers. A couple of times a year, a comet might reach magnitude +6 to +10 and become a fine binocular ob...
The Orion G4 has issues, also. The pixels are enormous, best suited to a big scope. The read noise is 7 electrons, which is a lot these days. It's a good camera for $500, but a good camera costs more than that. The 533 I recommended (good pixel size, low read noi...
the elements can be logically organized into a periodic table based on their physical properties. Substances in the same column on the table tend to have similar properties. This follows because elements in a vertical column have the same outer electron structures. These outermost electrons determine...
