FOUR CENTURIES of ATOMIC THEORY an Overview

FOUR CENTURIES of ATOMIC THEORY an Overview

It might seem oddly perverse to give a lecture entitled “Four Centuries of Atomic Theory” at a symposium entitled “200 Years of Atoms in Chemistry.” No one questions, of course, that the 19th- and 20thcenturies were the heyday of chemical atomism and historians of chemistry have long agreed that Dalton’s work was the starting point for our current quanti ...

A Consideration of Babylonian Astronomy Within the Historiography of Science

A Consideration of Babylonian Astronomy Within the Historiography of Science

This paper traces the reception of Babylonian astronomy into the history of science, beginning in early to mid twentieth century when cuneiform astronomical sources became available to the scholarly public. The dominant positivism in philosophy of science of this time influenced criteria employed in defining and demarcating science by historians, resulti ...

PLANET: Massively Parallel Learning of Tree Ensembles with Mapreduce

PLANET: Massively Parallel Learning of Tree Ensembles with Mapreduce

Classification and regression tree learning on massive datasets is a common data mining task at Google, yet many state of the art tree learning algorithms require training data to reside in memory on a single machine. While more scalable implementations of tree learning have been proposed, they typically require specialized parallel computing architectur ...

The History of Ancient Astronomy: Problems and Methods

The History of Ancient Astronomy: Problems and Methods

In the following pages an attempt is made to offer a survey of the present state of the history of ancient astronomy by pointing out relationships with various other problems in the history of ancient civilization and particularly by enumerating problems for further research which merit our interest not only because they constitute gaps in our knowledge ...

Philosophy of Science: an Overview for Educators

Philosophy of Science: an Overview for Educators

From the point of view of knowledge (or epistemologically), science is a method of inquiry about the things and structures in the world. Conceived of as a social human activity, science is an important institution or practice Constitutive of the modern world. Science has been heralded for much of the good in the world and much of its progress. It has als ...

Our Powerful Sun

Our Powerful Sun

Eight planets and their moons, tens of thousands of asteroids, and trillions of comets revolve around the sun. One of these is our Earth, orbiting the sun at an average distance of about 92,960,000 miles (149,600,000 kilometers). The sun is a huge, glowing ball that provides light, heat, and other energy to our Earth. But our beneficial space neighbor is ...

Scaling the Earth: a Sensitivity Analysis of Terrestrial Exoplanetary Interior Models

Scaling the Earth: a Sensitivity Analysis of Terrestrial Exoplanetary Interior Models

An exoplanet’s structure and composition are first-order controls of the planet’s habitability. We explore which aspects of bulk terrestrial planet composition and interior structure affect the chief observables of an exoplanet: its mass and radius. We apply these perturbations to the Earth, the planet we know best. Using the mineral physics toolkit Burn ...

From 3D Models to 3D Prints: an Overview of the Processing Pipeline

From 3D Models to 3D Prints: an Overview of the Processing Pipeline

Due to the wide diffusion of 3D printing technologies, geometric algorithms for Additive Manufacturing are being invented at an impressive speed. Each single step, in particular along the Process Planning pipeline, can now count on dozens of methods that prepare the 3D model for fabrication, while analysing and optimizing geometry and machine instruction ...

Atmospheric Physics Lab Work Evaporation

Atmospheric Physics Lab Work Evaporation

In the first part of this experiment, the relationship between wind speed and evaporation is investigated. We measure the evaporation under idealized conditions using a small wind tunnel. We then compare our results from the experiment with calculated values for the evaporation over the sea. In the second part of the experiment, we have a look at the win ...
