Andy Resnick replied to the thread The Secrets of Prof. Verschure's Rosetta Stones.Carbonatite, Fen complex. The Fen Complex experienced pluri-metasomatic processes consisting of at least two main phases of... -
Andy Resnick replied to the thread The Secrets of Prof. Verschure's Rosetta Stones.Carbonatite, Fen complex. This sample displays a transition from, on one side carbonatite, then, moving from left to right, an apparent... -
Andy Resnick replied to the thread The Secrets of Prof. Verschure's Rosetta Stones.Carbonatite, Fen Complex. This sample could be classified as Alvikite, but the real interest I have is in the bands of color that... -
Andy Resnick replied to the thread Random Photos.Really excellent photos- both compositionally and technically (exposure, etc)- thanks for posting! -
Andy Resnick replied to the thread The Secrets of Prof. Verschure's Rosetta Stones.Another altered carbonatite: Altered carbonatite. A veinlet of carbonatite intrudes into an existing carbonatite pluton, bisecting a... -
Andy Resnick replied to the thread Undergrad Can somebody explain this: Planck's Law in action.Yes, but the amount of energy radiated by the wire will be much lower than the sun. The amount of energy you need to absorb to protect... -
Andy Resnick replied to the thread Undergrad Can somebody explain this: Planck's Law in action.Interesting question- one I had not thought of. First, confined plasmas have a variety of radiation emission mechanisms, not just... -
Andy Resnick replied to the thread The Secrets of Prof. Verschure's Rosetta Stones.Carbonatite, Fen Complex. This sample has a significant amount of apatite, generally arranged either in aggregations of elongated... -
Andy Resnick replied to the thread Undergrad Why use Stefan's Law to measure temperature?.Well.... if you know the emissivity, then I would agree that a commercial IR detector/camera can hit that 5% accuracy. The problem is... -
Andy Resnick replied to the thread Undergrad Why use Stefan's Law to measure temperature?.But that's sort of my point- without any 'ground truth' data, it's not possible to accurately determine the temperature of an unknown...
